10 Jahre differenzierte Grundbodenbearbeitung im Ökologischen Landbau. Auswirkungen auf die Besiedlung mit Collembolen
Provedor de dados: 21
Autores: Bassemir, Ursula K.
During 10 years a crop rotation schedule consisting of different crops (green fallow; intercrop: winter wheat; peas; intercrop: winter rye; summer barley) was combined with three different tillage techniques (plough, inverting to 30 cm depth, intensive; two-layer plough, inverting to 15 cm depth and loosening to 30 cm depth, reduced inverting; layer cultivator, loosening to 30 cm depth, conservation tillage). First results show a significant effect of crop on springtails. There is no significant effect of tillage techniques, although there is a tendency in slightly increased population density of springtails by using plough and layer cultivator. Further detailed results will be reported elsewhere.

100% local and organic: closing the protein gap for poultry  in the ICOPP Project
Provedor de dados: 21
Autores: Nelder, Rebecca; Smith, Jo; Clements, Ruth; Pearce, Bruce.
A key challenge in improving the sustainability of organic poultry production is meeting the required levels of nutrients from locally sourced organic feeds. 100% organic diets for monogastrics will become compulsory in the EU from 1st January 2015. The ICOPP project brings together knowledge, from 10 EU countries, of local feeds for monogastrics and their wider impact on growth, health and welfare and the environment to identify feeding strategies which comply with organic principles. This poster will report on feeding trials carried out with broilers in the  UK by FAI and ORC to investigate the impact of algae, peas and lupins on broiler performance and welfare.

100% Organic Feed for Pigs – Results of Feed Trials in the UK
Provedor de dados: 21
Autores: Smith, Jo; Gerrard, Catherine L.; Nelder, Rebecca; Clements, Ruth; Pearce, Bruce; Zaralis, Konstantinos.
Current regulations for organic pig and poultry production systems permit feed ingredients of non-organic origin, primarily due to concerns that a 100 % organic diet would be unable to meet the demand for the essential amino acids lysine and methionine. 100 % organic diets for monogastrics will become compulsory in the EU from 1st January 2015, and so there is an urgent need to develop economically profitable feeding strategies based on organic feed across Europe. Feeding trials carried out with Gloucester old spot pigs in the UK found that there was no significant difference in the weight gains across the diets until the last week of the trial when there a significant difference in weight increase for the male pigs on the bean diet. This suggests that a...

100% Organic Feed for Poultry – Results of Feed Trials in the UK
Provedor de dados: 21
Autores: Gerrard, Catherine L.; Smith, Jo; Nelder, Rebecca; Clements, Ruth; Pearce, Bruce; Bright, Ashleigh.
Current regulations for organic monogastric production systems permit feed ingredients of non-organic origin, primarily due to concerns about meeting the demand for the essential amino acids methionine and lysine. However, 100 % organic diets will become compulsory in the EU from 1st January 2015, so there is a need to develop feeds which will supply the required level of nutrients and support high animal health and welfare. This paper reports on feeding trials carried out with broilers in the UK to investigate the impact of three 100 % organic diets: a control diet with globally sourced ingredients, a diet based on locally sourced (i.e. within Europe) organic ingredients, and a diet based on locally sourced organic ingredients and algae. The results of...

100%-Biofütterung mit Rapskuchen und heimischen Körnerleguminosen bei der Fütterung von Legehennen verschiedener Herkünfte
Provedor de dados: 21
Autores: Rahmann, Gerold; Holle, Romana; Andresen, B; Andresen, C.J.
Rations of 100% organic and local origin were tested. Up to 18% of thermally proc-essed rape cake was fed in different rations to two groups of laying hens. Faba beans, Vicia sativa and blue lupines were used as protein supplements to create a feeding ration. High vicine and covicine contents, especially in Vicia sativa, led to a refusal of some food rations. No ration has been found suitable for daily use. Chicken fed with a rape cake ration laid eggs with a positive fatty acid pattern, which is favourable for human diets.

10-year interdisciplinary monitoring of organic stocklass, vegetable rotations at Warwick-HRI, Kirton, South Lincolnshire, UK
Provedor de dados: 21
Autores: Schmutz, U; Rayns, F; Sumpton, P.
Interdisciplinary monitoring of an organic stockless farming system has been carried out over ten years on a fertile silty clay loam in the main vegetable production area of the UK. The results draw together economic outcomes with agronomy, soil science and agro-ecology. Organic management has been used at the Kirton research site since conversion of a 3.2 ha unit in 1997. There is great variability in crop yields and marketing results but overall a successful ongoing vegetable production system has been established. Soil fertility, weeds, pests and diseases have been managed successfully without imports of animal manures or green waste compost. Production costs are well controlled and marketable yields are good. However, because the site is a research...

15 years of research in organic food systems in Denmark – effects on the sector and society
Provedor de dados: 21
Autores: Rasmussen, I.A.; Halberg, N.
An analysis of the effect of 15 years of research in organic food systems in Denmark showed that it has had a high impact on the development of the sector. There are three main reasons: First of all, the content of research programs and the funded projects have been closely aligned with the needs of the industry as expressed by farmers, advisors and organizations. Second, many of the projects have had close contact to advisors and farmers securing continuous dissemination resulting in rapid application of results. Third, due to the close contact between researchers and users the research design has been adapted to ensure that treatments to be tested are as relevant and practical as possible, without compromising the scientific standards. Besides the...

15Nitrogen transfer from legumes to neighbouring plants in multi-species grassland
Provedor de dados: 21
Autores: Pirhofer-Walzl, K.; Høgh-Jensen, H.; Rasmussen, J.; Rasmussen, J.; Søegaard, K.; Eriksen, J.
This study investigates the N transfer from legumes to  neighbouring plants, grasses, legumes and herbs in a temperate grassland. In a field experiment white clover  (Trifolium repens), red clover (Trifolium pratense) and lucerne (Medicago sativa) were leaf-labelled with 15N enriched urea. The 15N tracer was measured in above-ground plant tissue of eight neighbouring plants in two subsequent harvests in 2008. The three legumes donated 15N to all neighbouring plants, of which grasses, white and red clover were strong receivers. Results show that N transfer increases with N application and from the 1st to the 2nd cut.

15Nitrogen uptake from shallow- versus deep-rooted plants in multi-species mixtures and monoculture grassland
Provedor de dados: 21
Autores: Pirhofer-Walzl, K.; Høgh-Jensen, H.; Rasmussen, J.; Rasmussen, J.; Søegaard, K.; Eriksen, J.
Only few studies have explored the importance of functional diversity in temperate agricultural grasslands in relation to nitrogen (N) uptake. This study investigates the consequence of growing deep-rooted plants together with grass-clover mixtures in terms of N uptake efficiency from deep soil layers. The objective was to compare the N uptake of the shallow-rooted grassland species Lolium perenne and Trifolium repens; and the deep-rooted species Cichorium intybus and Medicago sativa in monocultures and mixtures. We hypothesized that growing deep-rooted plant species in mixture with shallow-rooted species increases the N uptake from deep soil layers partly through competition. A 15N tracer study was carried out with 15N enriched ammonium-sulphate placed at...

Autores: Wolf, Dipl.-Ing. agr. D.; Hirte, Dr. K.; Schüler, Dr. C.; Heß, Prof. Dr. J.
For the understanding of ecological agriculture, knowledge of its roots is essential.  Actual literature about this topic does not cover the history of ecological agriculture in  East Germany especially if chronological development and individual motivation are  seen as mutual dependent. The ecological organisation Gäa e.V. was founded in the  GDR in 1989. Its origins were oppositional environmental groups working within the  East German church. It developed own principles based on individual experience with  unique aspects. It has established and integrated well in the German ecological agriculture  structure after the reunification and the changed political background as an  authentic representative of and for the East German ecological agriculture scene.

Autores: Bachinger, Johann; Bloch, Ralf; Reckling, Moritz; Stein-Bachinger, Karin.
Acht Felder der Versuchsstation des ZALF in Müncheberg in Nordostdeutschland wurden 1993 als Modellbetrieb mit einer Leguminosen-betonten Fruchtfolge auf Ökologischen Landbau umgestellt. Je Feld wurde 1995 ein Monitoringversuch mit je  5 Ernte- bzw. Beprobungsparzellen angelegt. Neben Ernteerhebungen erfolgte eine jährliche Krumenbeprobung zur Untersuchung der Entwicklung der Gehalte an organischem Kohlenstoff (Corg) und Stickstoff (Norg) sowie der P- und K-Verfügbarkeit. Eine deutliche Zunahme der Corg-Gehalte zeigte sich nur auf den Flächen mit Texturklasse Sand. Dagegen stiegen die Norg-Gehalte auch auf den besseren Böden, allerdings in geringerem Maße, an. Die P-Verfügbarkeit pegelte sich nach einem anfänglichen Rückgang auf Werte der Versorgungsstufe...

Provedor de dados: 21
Autores: Reckling, Moritz; Döring, Thomas F.; Bloch, Ralf; Stein-Bachinger, Karin; Bachinger, Johann.
Auf dem Modellbetrieb für Ökolandbau in Müncheberg wurden von 1993 bis 2013 Feldversuche zur Ermittlung der Ertragsstabilität von zwei Körnerleguminosen (Schmalblättrige Lupine und Futtererbse), Wintergetreide (Roggen und Weizen), Hafer und Silomais durchgeführt. Zwei orthogonale Datensätze wurden genutzt um die temporären Ertragsschwankungen der Einzelkulturen zu vergleichen. Beide Körnerleguminosen zeigten die geringste Ertragsstabilität von allen untersuchten Kulturen. Dies war sowohl für varianzbasierte als auch für regressionsbasierte Stabilitätsparameter der Fall. Gründe für die geringe Ertragsstabilität sind unzureichend bekannt. Es müssen Strategien für das Management entwickelt werden, um mit den großen Schwankungen umzugehen.

2011 Approaches for organic food and feed authentication
Provedor de dados: 21
Autores: van Ruth, S.M.; Alewijn, M.; Tres, A.; van der Veer, G.
People’s growing awareness of health, environment and animal welfare has led to an increased public interest in the quality of foods and food production systems. This in turn boosted organic production. Due to higher production costs, organic produce tends to retail at a higher price than their conventional counterparts. As a consequence of the premium price, organic produce is susceptible to fraud. Fair competition between producers and sustained consumer confidence favour organic production, and it requires regular confirmatory assessments of the identity of organic produce in addition to administrative controls.     Traditional analytical strategies for guaranteeing quality and uncovering adulteration have relied on the determination of the amount of a...

Autores: James, K.; Akyüz, M.; Niggli, U.; Ramprasad, V.; Chable, V.
Recent developments in organic farming and consumption show dynamic growth in markets; new uptake of Organic Agriculture by farmers, however, has been slow. Hindrances appear to be production problems or lack of trust by the farmers that organic methods can solve farming problems, such as fertilization, plant protection, animal health, efficient use of workforce, marketing diversity etc. While in some cases those problems can be solved through learning existing and regionally practiced methods, innovations are imperative to make organic farming competitive and a viable alternative farming system.

Farming since 1983, Vehbi Ersoz always thought there were some problems with the conventional farming methods. Using a different pesticide for each varmint and a different fertilizer for each missing substance in the soil made him question the function and procedures in conventional agriculture. Favoring a more holistic perspective in agriculture, he tried many methods to enrich the soil and increase the soil microorganisms, which in turn do the actual work. In his region he brought many leading and innovative techniques to life. Some of them are greenhouse farming, organic farming, biodynamic agriculture and Shumei method of agriculture. As a side benefit of applying many different techniques, he discovered that methods applied in one philosophy, may in...

Autores: Cisilino, Federica; Madau, Fabio A.
This paper presents some results from a wider research on economic and environmental sustainability of organic farming. It aims to compare organic and conventional farming in order to identify some of the main differences between those groups of farms that participated in the official Farm Accountancy Data Network (FADN)-2003. The study is organized in two sections. The first part, after a brief literature review of the most recent statistical methodologies applied to identify the two similar groups of farms, presents some key economic variables (production, costs and revenues) and the most widely-used structural, economic and balance sheet indexes.  The second part describes findings from a case study on the Italian fruit-growing sector.  A non-parametric...

Organic Animal Farming (OAF) systems hold a major part in Organic Agriculture (OA). Alternative protein crops are essential in the development of OAF in order to substitute technically and economically non-acceptable protein sources in Organic Animal feeding.   A study, aiming to compare white lupine (Lupinus albus cv Multitalia) and fava bean (Vicia faba cv Vesuvio) crops, was undertaken in Central Greece. The study compared the two plant species under organic or conventional management regimes in terms of quantity and quality produced. There were no productivity or quality differences between the regimes.

A comparison between organic and integrated apple production: First results after 5 years of observation
Provedor de dados: 21
Autores: Kreuzwieser, Andreas; Kelderer, Markus.
Organic apple production is of increasing commercial importance throughout Europe, but  especially in South Tyrol where about 25% of the whole European organic apple crop is  produced.  In organic apple production, producers face the challenge of choosing varieties that are  both in demand and also resistant to the main pests and diseases. Every now and then,  the question arises, if yields, losses and profitability are different in integrated and organic  orchards and in how great are the differences between single apple varieties.  In 1999 the Laimburg Research Centre started a field trial to observe the effects of  different cultivation methods on 18 apple varieties in a randomised block design. In the first  four years of production, significant...

A comparison of energy use in organic and conventional agriculture in Spain
Provedor de dados: 21
Autores: Alonso, Antonio M.; González, Rodrigo; Foraster, Laia; Guzmán, Gloria I.; García, Roberto.
The current situation of worldwide concern over the emission of greenhouse gases and its effect on the climate demands an evaluation, from the perspective of energy efficiency and more specifically of non-renewable energy sources, of tendencies for change in the management of agricultural systems that have arisen in recent years. This article uses energy balances to evaluate the contribution of organic agriculture to the increase in the energy efficiency of Spanish agriculture. The results show the higher nonrenewable energy efficiency (NREE) and the lower use of nonrenewable energy (NRE) in organic systems compared with conventional ones. Nevertheless, agricultural systems in general could still improve their energy efficiency.

One of the primary challenges of our time is develop sustainable farming systems that can feed the world with minimal environmental impact. Some studies argue that organic farming systems are best because these have minimal impact on the environment and are positive for biodiversity. Others argue that no-tillage systems are better because such systems save energy and preserve soil structure and quality. A third group argues that conventional farming systems are best because yield per hectare is highest. However, so far, systematic comparisons of major arable production systems are rare and often it is difficult to compare the advantages and disadvantages of farming systems in a systematic way due to differences in soil/site characteristics and management....

Autores: Tabaglio, Prof. Vincenzo; Gavazzi, Dott. Carolina; Nervo, Dott. Giuseppe.
A four-year field trial (2004-2007) was carried out to compare performances of organic and conventional farming systems in the Po Valley (Northern Italy). Four vegetable crops were grown in the sequence: 2004 – processing tomato; 2005 – bean followed by savoy cabbage; 2006 – processing tomato; and 2007 – zucchini. The experimental design was a split-plot with four replicates, the management system being the main factor (OF, organic farming vs. CF, conventional farming) with the rate of nitrogen fertilisation as the secondary factor. N efficiency of the organic fertilizers was assumed as being 50-75%). In all four of the years studied, the two farming systems did not show significant differences in marketable yields for any vegetable crops. The reduction in...

A comparison of soil properties under organic and conventional farming in Australia
Provedor de dados: 21
Autores: Nachimuthu, Gunasekhar; Kristiansen, Paul; Lockwood, Peter; Guppy, Chris.
Organic farming is an alternative to conventional farming for providing sustainable crops with high export demand. This review analyses research findings on organic farming in Australia, with an emphasis on soil health. Several reports have indicated that organic farm management generally improves soil physical properties in Australia and elsewhere. Although low nitrogen (N) availability can constrain yields, organic farmers can improve N supply through legume green manures. Plant available phosphorus (P) is a more serious limiting factor in organic farming, particularly in Australia with naturally low P levels. Phosphorus is less easily replaced in the soil than N, and there is a need for alternate sources of organic-certified P and methods to enhance P...

A  COMPARISON OF STRATEGIES FOR WEED MANAGEMENT IN NATURE FARMING
Provedor de dados: 21
Autores: Sangakkara, U.R.; Amerasekera, P.; Bandaranayake, P.R.S.D.
Weeds are a major problem in organic or Nature Farming systems and mechanical methods are generally used for weed control. However either mulching or growing crop in-between rows of the principal crop offers scope as a means of protecting soil and suppressing weeds. Field studies thus evaluated the impact of either a mulch or growing two intercrops as possible management strategies for controlling weeds of vegetables grown in major and minor seasons of the tropics under a Nature Farming regime. All three strategies controlled weed numbers, their biomass and increased crop yields. However the least beneficial impact was from the dead leaf mulch, while the highest degree of weed control and increments in crop yields was with the green manure intercrop. The...

A Conceptual Framework for Soil management and its effect on Soil Biodiversity in Organic and Low Input Farming
Provedor de dados: 21
Autores: Koopmans, Dr. C.J.; Smeding, Dr. F.W.
Learning how to manage beneficial soil biological processes may be a key step towards developing sustainable agricultural systems. We designed a conceptual framework linking soil management practices to important soil-life groups and soil fertility services like nutrient cycling, soil structure and disease suppression. We selected a necessary parameter set to gain insight between management, soil life and soil support services. The findings help to develop management practices that optimise yields, soil fertility and  biodiversity in organic farming.

A critique of methodologies for the comparison of organic and conventional farming systems
Provedor de dados: 21
Autores: Lee, Howard; Fowler, Susan.
This paper was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).  A review is presented of comparative studies of organic and conventional farming systems, with a special focus upon economic criteria. The different categories of comparison methodologies are critically reviewed. Conclusions are that classic experimentation has a valuable part to play but that more qualitative assessment can also be useful and should be encouraged. Careful allowance should be made for major background differences in management when comparing financial profitability. Longer term case studies, which try to monitor organic systems in their own right, should also be encouraged.

A deductive approach to animal health planning in organic dairy farming: Method description

Autores: Selle, Margret; Hoischen-Taubner, Susanne; Sundrum, Albert.
Organic farming is often directly associated with an enhanced level of animal health and welfare. However, in spite of ongoing efforts in the fields of animal science, the animal health status in organic dairy farming does not in all respect meet consumers’ expectations. Reasons are manifold and differ considerably between farms as do the multi-factorial production diseases. Success of animal health planning highly depends on a sound diagnostic procedure at farm level and farmers’ intrinsic motivation to improve the animal health status. Both aspects are essential preconditions for the identification and implementation of the most appropriate farm-specific management measures.  The aim of this paper is to introduce a participatory and farm-centric...

A discussion of norms for S supply in organic farming based on content in forage and ruminant performance in Norway
Provedor de dados: 21
Autores: Hansen, Sissel; Bakken, Anne Kjersti.
The content of sulphur (S) in grassland on 27 Norwegian organic farms with dairy or sheep production was investigated in 2001 and 2002. The forage content of S was below the norms (2 g S kg DM-1) for both plants and animals in a large proportion of the samples. The average S content in forage at dairy farms was 1.4 g S kg DM-1 and at sheep farms 1.5 g. Even on grasslands with low plant S content (&lt;1 g S kg DM-1), S-fertilization did not increase yields and increased the plants’ S content only very slightly. No indications of S deficiency were observed on the dairy farms. For one sheep farm with a forage S content of 1.1 ± 0.1g S kg DM-1, brittle and short winter wool was reported.

A four-year comparison of two organic dairy systems
Provedor de dados: 21
Autores: Weller, Mr Richard.
Two organic systems were studied, the first based on self-sufficiency (SS) and the feeding of high-forage diets, and the second on purchased concentrates (PC) and maximising milk output. The growing of both concentrate and forage feeds in the SS system reduced the stocking density. Feeding high-forage diets increased the proportion of milk produced from forage but decreased the energy concentration of the ration, leading to lower milk persistency, reduced milk protein in early lactation and reduced pregnancy rates. In the PC system importing feed increased the stocking density but also increased the ‘farm-gate’ nutrient surpluses.

A framework for assessing crop production from rotations
Provedor de dados: 21
Autores: Topp, Cairistiona F E; Doyle, Chris J; Watson, Christine A.
This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).  Organic farming systems rely on the management of biological cycles for the provision of nutrients, which are crucial to maximising the production from the system. Rotations based on the use of grass-legume leys are central to the concept of organic farming systems, because they have the potential to support both animal production, and a subsequent, exploitative, arable cropping phase. A major challenge in organic farming is managing the supply of nitrogen, since it has a key role in governing both productivity and environmental impact. Hence, within a rotational system, there is a need to understand the complex interactions that are...

Provedor de dados: 21
Autores: Thatcher, A; Petrovski, K; Holmes, C; Dowson, K; Kelly, T; McLeod, K.
Mastitis in two herds managed as a comparison between organic and conventional dairy farming systems was monitored for 4 years utilising regular bacterial culture of milk samples, individual and bulk somatic cell counts and observation by farm staff. The objective was to develop strategies for the control of mastitis in organic cows without the use of antibiotics. The herds showed differences in clinical mastitis incidence, subclinical mastitis prevalence and bulk milk somatic cell count. Despite these differences, the level of mastitis in the organic herd remained manageable.

Autores: Mata, Macarena; Garrido, Marisol; Longhurst, Phil; Seaton, Roger.
This paper was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).  The regulation for the assessment of the conversion to organic farming establishes the use of soil/produce pollution and the type of agricultural practices as indicators of performance. However, these indicators don’t reflect the complexity of the soil ecosystem and soil health. Therefore, complementary indicators were sought (soil biostructure and field capacity), and a specific three-steps method for the assessment and monitoring of soil health during the conversion process was developed.

Manufacturing and also maintenance and repair energy demand is hard to find, there are only few research data available and this data seems no to be very reliable. Manufacturing energy damand can be calculated by estimating the mean tractor usage and calculating the manufacturing energy per consumed fuel liter. In this way it is easy to estimate the manufacturing energy, because it can be calculated with the liter/ha figures.

A methodological framework for analysing landscape dynamics in relation to organic farming

Since the mid-1980’ies Danish agriculture has been subject to a growing conversion into organic farming. Today roughly 6% of the cultivated land is farmed organically. Consequently, organic farming has a growing impact on the Danish agricultural landscape.  It is generally expected that conversion to organic farming leads to landscapes with a rich and diverse nature. However, for organic farming in Denmark there exist no specific rules or guidelines concerning conservation and/or improvement of nature values at landscape scale. A positive effect of organic farming techniques on nature content within cultivated fields is relatively well documented.

A model analysis on nitrate leaching under different soil and climate conditions and use of catch crops
Provedor de dados: 21
Autores: Pedersen, Anders; Stoumann Jensen, Lars; Thorup-Kristensen, Kristian.
The use of crops and catch crops with deep rooting can strongly improve the possibility of retaining nitrate-N that will otherwise be leached to the deeper soil layers and end up in the surrounding environment. But will it always be an advantage for the farmer to  grow a catch crop? This will depend on factors such as soil mineral nitrogen level, soil water holding capacity, winter precipitation, rooting depth and N demand of the scceeding crop. These factors interact, and it can be very difficult for farmers or advisors to use this information to decide whether growing a catch crop will be beneficial. To analyse the effect of catch crops under different Danish soil and precipitation conditions, we used the soil, plant and atmosphere model Daisy.

The main challenge for organic farmers, millers and bakers is to fulfill consumers’ expectations of providing healthy and safe products. The quality of organic grain can be modulated by agronomic modifications on genotypes, crop management, crop rotation and soil fertility, but the milling process and finally the baking process are also key factors in producing bread of high baking quality, nutritional value, taste and flavour. Nitrogen (N) is a key nutrient in achieving acceptable yield levels of sufficient bread-making quality, but previous results have shown that organic wheat tends to have lower protein content, dough mixing tolerance and loaf volume.

A New Approach to Humus Balancing in Organic Farming
Provedor de dados: 21
Autores: Brock, Christopher; Hoyer, Uta; Leithold, Günther; Hülsbergen, Kurt-Jürgen.
Humus balances provide a profitable approach for humus dynamics assessment in farming practice. Nevertheless, there is a clear demand for methodological adaptation.     This article presents a new approach to humus balancing using reproducible algorithms for the estimation of balance coefficients. Humus balance coefficients for crops and organic fertilizers are estimated according to a bipartite algorithm. Humus demand  is calculated on the basis of crop yields referring to the nitrogen household in the plant-soil system. Humus supply is derived from organic matter input with plant material and fertilizers. The new approach facilitates the adaptation of the method to new situations.

Autores: Vedie, Hélène; Berry, Dominique; Leclerc, Blaise; Grébert, David; Lhôte, Jean-Michel.
The effect of controlled traffic with permanent crop beds was compared to mouldboard ploughing in France for organic vegetable production. Four trials were carried out over a period of three to seven years at four sites with different pedo-climatic conditions. Variable results were obtained, depending on soil type (susceptibility to compaction), tillage machinery type, vegetable type (root or not, grown from seed or transplant) and weed development. However, permanent crop beds with controlled traffic generally improved biological activity and reduced labour demand.

A new engineering method is proposed to understand extrudate expansion and extrusion operation parameters for starch based food extrusion cooking process through dimensional analysis principle, i.e. Buckingham pi theorem. Three dimensionless groups, i.e. pump efficiency, water content and temperature, are suggested to describe the extrudate expansion. Using the three dimensionless groups, an equation is derived to express the extrudate expansion. The model has been used to correlate the experimental data for whole wheat flour and fish feed extrusion cooking. The average deviations of the correlation are respectively 5.9% and 9% for the whole wheat flour and the fish feed extrusion. An alternative 4-coefficient equation is also suggested from the 3...

A New Incarnation- The Role of the Organic Growers  Association in Changing the Production and Marketing  of Organic Produce
Provedor de dados: 21
Autores: Frost, David; Wacher, Carolyn.
Although there is a widespread assumption that organic farming developed in response to the intensification of agriculture in the second half of the twentieth century, a number of scholars have sought to show that the origins of the movement date to the 1920s and 1930s. They argue that that there is continuity in the development of the organic movement and that the ideals and values of the early organicists are the origin of current organic farming discourse. A detailed history of the organic movement indicates however, that a number of social movements converged to contribute to its development. Particular cultural and socio- demographic changes in the last three decades of the twentieth century produced a new ex-urban organic movement with a new organic...

The prairie ecosystem that occupied most of the North American continent has been mostly converted into agricultural farmland.  The looming global scarcity of fossil fuels has spurred interest in producing ethanol from corn (Zea mays) but legitimate objections remain to the idea of supporting this vision.  The purpose of this study was to initiate a prairie restoration on marginal soil of a 16.2 ha. farm in southeastern Minnesota and to determine which restoration procedure (only native grass species versus a mixture of grasses and forbes) was most effective for the establishment of prairie on the land that may yield biomass for biofuels.  We planted 11.4Kg./ha. of grasses on 4.7 ha. and 0.70Kg./ha. of forbs on 3.2 ha., in June 2007.  An evaluation of...

A non-chemical method for monitoring adult olive weevil populations in Tadla-Azilal plain in Morocco
Provedor de dados: 21
Autores: EL JIATI, Abdelazize.
The olive weevil becomes one of the major olive pests in Tadla-Azilal in Morocco. The chemical control is expensive and of low efficiency. Its application at night complicates the task for olive growers. An alternative non-chemical method has been developed using polyester fiber as a trap. It has a high efficiency, low cost and might be advised to organic olive farmers.

Autores: Clarke, Dr Sarah M.; Hinchsliffe, Miss Kay E.; Haigh, Miss Zoe; Jones, Dr Hannah; Pearce, Dr Bruce; Wolfe, Prof Martin S; Thomas, Dr Jane.
A participatory research methodology was used to compare the performance of UK wheat varieties under organic conditions. Plots of three breadmaking winter wheat varieties (Hereward, Solstice and Xi19) and a mixture (1:1:1) of the varieties were grown at 19 UK farms in two seasons (2003/04 and 2004/05). Meas-urements were taken of growth habit, yield and grain quality. Grain yields in both seasons showed significant site by variety interactions, although the variation among sites was greater than among varieties in both instances. Wheat grown at Western sites was significantly shorter and higher-yielding than that grown at Eastern sites in 2003/04 but significantly taller in 2004/05. As with grain yield, greater variation among site than variety was found...

Farmer participation was essential in developing a uniquely useful set of wheat variety trials data on a wide range of organic farms over two years. Although the trials were successful, it became clear that some of the participating farmers felt there were some limitations in the process. These included a lack of ownership in the project and a concern for more researcher help. It was clear that a greater time in-vestment was needed at the start of the project to help with farmer understanding and ownership. De-spite the negative comments, farmers appreciated their involvement, particularly in contrasting their own views and information with that from the wider scene.  Farmer participation is essential for systems-level research and this project helped to...

Autores: Nuutila, Jaakko.
The Finnish Government has set development goals for organic food chain. Following the actions presented in this paper, it is possible to develop the organics in the Finnish food chain holistically and comprehensively to reach the goals. The increase in production and consumption will have proven positive impact to the wellbeing of people, nature and animals. Arctic and safety features of Finnish food will enhance the export possibilities of organic food to partly correct the current negative trade balance. The development is possible when organic values are incorporated to the Finnish food chain supported by the Nordic welfare model.

A Policy Impact Model for Organic Farming in Switzerland
Provedor de dados: 21
Autores: Sanders, Juern; Lampkin, Nicolas; Midmore, Peter; Stolze, Matthias.
Although organic farming has expanded significantly in Europe in the last decade, a sectoral policy model is still missing that is able to analyse the impact of policy measures on organic farming. The use of programming models in the form of a sector-consistent farm group model seems to be a promising model approach, whereas applied general equilibrium models are regarded as less promising. An example is given for a policy impact model for organic farming. The bottom-up structure of this type of model makes it possible to analyse the impact of policy measures on farm incomes and volumes of production of organic and conventional farms at farm, regional and sectoral level.

A PRACTICE APPLICABLE MODEL FOR THE ASSESSMENT OF MANAGEMENT IMPACT ON ORGANIC MATTER IN ARABLE SOILS
Provedor de dados: 21
Autores: Brock, Christopher; Leithold, Günter.
We present the HU-MOD-2 model for the assessment of management impact on organic matter levels in arable soils. The model aims at optimal applicability as a management support tool in framing practice and therefore requires only easily available input data. In validation, the tool proved to be capable of giving a rough estimate on soil organic matter changes in arable soils. Taking into account the low demand for input data, the modeling error seems tolerable for a practice applicable decision support tool.

A semiotic polyocular framework for multidisciplinary research in relation to multifunctional farming and rural development
Provedor de dados: 21
Autores: Noe, Egon; Alrøe, Hugo Fjelsted; Langvad, Anne Mette Sørensen.
The concept of multifunctional farming rises out of a problematization of the role of agriculture in society and, in particular, in relation to rural development. Hitherto multifunctional farming has primarily been used as a notion on the relationship between agriculture and society concerning the range of commodity and non-commodity goods that farms provide for society. But the agro-economic achievements together with societal development have led to a point where praxis is questioned and discourse potentially reopened. In an indirect way, the notion of multifunctionality reflects, that aspects not captured by the distinction between commodity and non-commodity need to be reintroduced.  This paper offers a new framework (theoretical and methodical)...

Provedor de dados: 21
Autores: Thatcher, A.; Petrovski, K.; Shadbolt, N.; Martin, N.
Mastitis in two herds managed as a comparison between organic and conventional dairy farming systems was monitored for 9 years utilising regular bacterial culture of milk samples, individual and bulk somatic cell counts and observation by farm staff. The most important isolates in pure cultures were coagulase-negative staphylococci, Staphylococcus aureus, Streptococcus uberis, and Bacillus spp. Positive cultures were generally not associated with subclinical mastitis. The objective was to develop strategies for the control of mastitis in organic cows without the use of antibiotics. Within a set of key control measures, two management strategies were trialled, one of which reduced the prevalence of subclinical mastitis to very low levels.

Local adaptations of the IPCC methodology (http://www.ipcc.ch) are applied in different countries. They include a combination of theoretical, experimental and simulation methods for evaluating the activity and factors indicated N2O emission. The N2O emission from agricultural soil is considered an important source both for environmental impact and non-industrial losses of nitrogen (Petersen, Olesen, 2002). In this study a multifactorial approach, based on dynamic modelling, is used at a farm/field level to estimate N2O emission from grassland. For this purpose an algorithm for modeling of gaseous N2O emission was developed and analyzed.

The concept of sustainability is widely used in agriculture. There i, however, a large variability in the interpretation of the meaning of sustainability. The broad understanding in conjunction with the complexity of livestock farming calls for a systems approach.  In this paper different interpretation of sustainable agriculture id described and discussed. It is concluded that sustainable agriculture has a major normative dimension and obviously has different meanings for different groups in society. Using sustainability in a system describing concept, one has to be very aware of the normative dimension.

A territorial approach to organic farming: the case of eco-regions in Austria
Provedor de dados: 21
Autores: Schermer, Markus.
The ongoing changes from an agricultural to a rural society require from farmers to define their position new. Organic agriculture provides a value system which is well accepted by non-agricultural rural stakeholders and can therefore be a potential starting point for territorial sustainable development. In Aus-tria the approach of eco-regions (Bioregioen) provides such an approach. The paper gives some preliminary results on the preconditions necessary for the establishment of such an approach building on the results of an ongoing national project. Furthermore different strategies how to position the organic agenda within the framework of various regional development strategies are discussed.

Provedor de dados: 21
Autores: Rosenfeld, Simon; Parzies, Heiko; Grando, Stefania; Ceccarelli, Salvatore.
In a decentralized and participatory plant breeding (PPB) program, in contrast to conventional plant breeding, farmers select from a large number of genotypes over a number of cycles in several locations. As selection is for location-specific adaptation a PPB program based on, for example, four stages of selection, generates large, unbalanced data sets. With common spreadsheet software it is not possible, or it is at least very cumbersome to extract all the information, particularly the one that is related to genotype x environment (GE) interactions. Therefore, there is a need for an information system that makes it as easy as possible to retrieve and compare data over all given factors in the PPB-program. Due to a lack of education and financial resources...

ABILITY OF COMMERCIALLY AVAILABLE SOYBEAN BRADYRHIZOBIA INOCULANTS FOR COOL GROWING CONDITIONS IN CENTRAL EUROPE
Provedor de dados: 21
Autores: Zimmer, Stephanie; Messmer, Monika; Haase, Thorsten; Mindermann, Anke; Schulz, Hannes; Wilbois, Klaus-Peter; Hess, Jürgen.
In Central Europe the inoculation of soybean (Glycine max (L.) Merr.) with different Bradyrhizobia inoculants has led to unsatisfying nodulation results under low temperature conditions. The aim of this study was to test the capacity of commercially available inoculants under cool growing conditions in Central Europe. In 2011 and 2012 four Bradyrhizobia inoculants were tested on three early soybean varieties in a field trial in Germany. The number of nodules, yield and protein content were assessed. Two years data showed a successful nodulation of Product 4, Product 3 and Product 2 while Product 1 cannot be recommended. Independently of soybean variety, all of the three successful inoculants can be advised regarding grain yield. Protein content and protein...

Ability of new durum wheat pure lines to meet yield stability and quality requirements in low input and organic systems
Provedor de dados: 21
Autores: Colomb, B.; Desclaux, D.; Debaeke, P.; Justes, E.; Burger, P.
Low-input production schemes adopted in organic or conventional farms require crop varieties that combine good product quality and high yield stability under non optimal environmental conditions (Gooding et al., 1999). These traits are not yet found among the durum wheat genotypes available in France. Consequently the cultivation of this crop is hardly successful in stockless organic farms in southern France, which are characterised by very low nitrogen resources. Some hopes emerged with the identification of new durum wheat pure lines with a high grain protein content in breeding experiments conducted near Montpellier in 2001 and 2002. The aim of the present work was to confirm and elucidate the origin of the enhanced protein performance of these new...

Provedor de dados: 21
Autores: Huber, Julia; Siegel, Thomas; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
The increasing demand for bioenergy and the combination of agricultural production with conservation has made agroforestry to a sustainable land-management option. Aboveground woody biomass plays a decisive role considering the economic value of the agroforestry systems as well as the carbon storage. With the objective to study aboveground woody biomass production of agroforestry systems with different cultivation methods (organic/ integrated), short rotation plantations of different tree species were established 2009 and coppiced in 2012. The studied tree species were black alder (Alnus glutinosa), black locust (Robinia pseudoacacia), poplar “Max 3”, (Populus maximowiczii x Populus nigra) and willow “Inger” (Salix triandra x Salix viminalis).

In order to assess the risk of the use of recycled phosphorus (P) fertilisers for organic farming, the potential accumulation of heavy metals in soil after a 200-year fertilizer application equivalent to 11 kg P ha-1 yr-1 was calculated in a mass balance approach. Both fertilizers currently allowed in organic farming and recycled P fertilizers were regarded. For heavy metals, four scenarios with two soil pH levels (pH 5 and pH 7) and two precipitation excess levels (F 0.1 and F 0.3 m yr-1) were calculated. Recycled P fertilizers like struvite, meat- and bone meal, ashes, sewage sludge and digestate, as well as phosphate rock and triple superphosphate had a higher P content and a lower heavy metal-to-P ratio than composts. Consequently, compost application...

To describe spatial heterogeneity of crop properties, non-destructive methods can be helpful in capturing whole field data sets. This paper shows examples of different sensor methods that have been evaluated to measure biomass and legume content in legume-grass mixtures. Biomass has been estimated using vegetation indices (NDVI, SR, EVI and REIP) calculated from spectral reflectance measurements in greenhouse experiments. The index REIP has been used to identify species composition as well. Furthermore, biomass values can be derived from ultra sonic measurements of sward heights. To quantify legume contents in short term leys, which is important for forage quality and nitrogen flows, image analysis tools have been used in different experi-ments with good...

Abundance of naturally occurring entomopathogenic nematodes and establishment of inoculated Steinernema feltiae in an organic cropping system
Provedor de dados: 21
Autores: Nielsen, Otto; Philipsen, Holger.
The abundance of entomopathogenic nematodes and soil dwelling stages of plant specific insects was studied in an organic cropping system for two years. In addition was the survival of an inoculated strain of Steinernema feltiae studied. The abundance of naturally occurring entomopathogenic nematodes was in general at a low level throughout the observation period (0-26 % positive samples). Inoculated S. feltiae established well when pea was grown in the same or in the following year whereas the nematodes were less able or unable to establish in the other crops (cabbage, carrots, barley, alfalfa/clover). The successful establishment of nematodes, and the abundance in general, correlated well with the presence of plant specific insects.

Autores: Ertem, A.; Menon, M.K.; Bernet, T.
The global Organic market for food has expanded to upwards of US$ 60 billion in consumer purchases annually. However, the market is concentrated in only a few countries, mostly in Europe and North America, and the global market share is far below 1%. We need further developments if the aspirations of the Organic World to provide solutions to global challenges are to be realized. The market and the attractiveness of Organic products on the market are changing, so that we need to adapt. The positioning of Organic products in the various markets, the responses of the Organic Sector to upcoming concerns, the transparency of processes and products, and the reporting of impacts are issues to which marketers need to be up to date.

In recent years the institutional framework of the organic certification system has step by step become a more formal and state run system. Our research shows that al-though the majority of the farmers accept the system, they are not convinced of its cost-benefit relationship. Farmers prefer a more association- and advice-oriented control of the organic certification process.

The aim of this study was to establish the degree of the acceptance of organic food production and food in the Finnish food chain. The organic food system in Finland is poorly developed and one of the many reasons is that the food chain stakeholders are not committed and do not share common objectives for organic food and its production. A survey was carried among 1527 respondents from agriculture, industry, retail, catering and consumers to establish their opinions on safety and healthiness of organic food, and ecology and ethicality of organic production as well as the support that their own environment provided to their opinions. The results show that all environments are very positive for all four attributes. The best support for positive opinions on...

Arable plants are becoming increasingly rare in today's cultural landscape and belong to the most endangered plant species in Luxemburg. Their main threat is the intensification of agriculture, where high usage of pesticides and fertilizer, better seed cleaning methods and the abandonment of marginal yield sites all negatively affect arable plant communities. Another factor is the loss of (potential) habitat due to the expansion of settlements and subsequent loss of agricultural lands. The dire situation calls for urgent action. Within the framework of the bachelor thesis of the first author, a concept for the protection of arable plants in Luxembourg was developed. The  following article describes and discusses the four most promising applied approaches...

This report was presented at the UK Organic Research 2002 Conference. Much research on animal health and welfare assumes that animals passively endure the pathogens, diet, and environmental conditions that come their way. Natural selection however has honed behavioural strategies for optimising health. Some of these involve the selection of ‘medicines’ to modulate health. Although it is not yet known to what extent domestic species retain the ability to self-medicate, it is vital that researchers acknowledge the potential role such behaviour might play when designing research protocols

To ensure the seed quality and the perfect storage place &amp; methods, women hold the vast knowledge. They decide the quantity and variety of seed to be saved and the method of preservation. Seed selection by women is a continuous activity. Working in the fields, they observe the plants and decide which seeds to select. They identify plants of good quality on the basis of size, grain formation and their resistance to pests and insects. Here a woman looks at the seed...

Acquiring plant features with optical sensing devices in an organic strip-cropping system
Provedor de dados: 21
Autores: Krus, Anne; van Apeldoorn, Dirk; Valero, Constantino; Ramirez, José Juan.
There is an increasing market for organic agriculture (Golijan &amp; Popovi\vs, 2016). However, the lack of attention for biodiversity and soil fertility of current practices is a pressing issue. The SUREVEG project (CORE Organic Cofund, 2018) therefore looks at strip-cropping in organic production and its implementation in intensive farming to improve soil fertility and biodiversity throughout Europe. The aim is to enhance resilience (Wojtkowski, 2008), system sustainability, local nutrient recycling, and soil carbon storage (Wang, Li &amp; Alva, 2010) among others. To counteract the additional labour of a multi-crop system, a robotic tool is proposed, which will operate upside down suspended from a wide-span mobile carriage. Within the project framework,...

By heating up carbohydrate-rich food, like cereals and potatoes, Acrylamide (AA), a  probably carcinogen food ingredient, will be created due to a reaction of free Asparagine  (Asn) and reducing sugar within the Maillard-Reaction. Up to now two opportunities  to decrease AA are discussed. Firstly by changing technological food processing  steps e.g. receipt modifications and secondly by plant production e.g. finding species  and cultivars low in the content of precursors of AA. For cereals, free Asn is the limiting  factor for formation of AA. By investigations of conventionally produced wheat-,  spelt- and rye samples differences were found in the amount of Asn both in species  and cultivars. It was assumed that these differences could also be found in...

The EU has put innovation at the heart of its strategy for achieving smart, sustainable and inclusive growth. In comparison with earlier EU research policy, the focus has shifted from research for its own sake to innovation with tangible impact. Putting ideas into practice has become the central goal of Horizon 2020, the EU's Framework Programme for Research &amp; Innovation for 2014-2020. This evolution also affects Europe's food and farming sector. Innovation support will be strengthened in the EU’s Common Agricultural Policy (CAP). Among the different measures that are foreseen in the CAP for 2014-2020 is the creation of a European Innovation Partnership for Agricultural Productivity and Sustainability (EIP) that should close the gap between research...

Autores: Leach, Katharine; Barker, Zoe; Maggs, Clare; Sedgwick, Anouska; Whay, Helen; Bell, Nick; Main, David.
Sixty-seven organic producers were among 189 dairy farmers completing the “Healthy Feet Project” in the UK. This aimed to reduce lameness in dairy herds by implementing existing knowledge. Participants received input at two levels: monitoring alone, or monitoring with extra support through a single veterinary advisory visit, annual visits from a trained non-veterinary facilitator and materials and contacts to encourage change. On average lameness on organic farms reduced by 12 percentage points over the three year period. On the farms achieving the greatest reduction,the most common changes were improvements to tracks and cubicle comfort, and more frequent footbathing or foot trimming. Practices to improve foot cleanliness, such as more frequent removal of...

The world’s biological diversity is eroding. This concerns in particular the entire agri-cultural diversity of genes, species and their agrarian ecosystems, the resource base for food. With species becoming extinct, mankind is jeopardised. With climate change becoming reality, genetic resources are getting a new value as they are of vital impor-tance for adaptation. This calls for a revision of present conservation approaches. Emphasis has to be placed on in-situ conservation in order to allow a maximum of species conserved and to enable species adaptation to environmental change.

Adapted vs. conventional cattle genotypes: sustainability for organic and low input dairy production systems
Provedor de dados: 21
Autores: Zollitsch, Werner; Ferris, Conrad; Sairanen, Auvo; Rinne, Marketta; Steinwidder, Andreas; Horn, Marco; Moorby, Jon; Vestergaard, Mogens.
Dairy cow strains arising from conventional breeding programmes are frequently perceived as unsuitable for organic and low input milk production systems. While farmers have identified a number of breeds and strains as being ‘adapted’ to organic and low input systems, there is often little scientific evidence to indicate that these breeds are more appropriate than conventional genotypes.  Thus the purpose of this study is to examine the response of different dairy genotypes (i.e. "conventional" versus "adapted") to an undersupply with nutrients and energy, which is a characteristic of low input systems with limited dietary supplementation and to provide information on the metabolic response of dairy cows to such dietary restrictions.

Adding more value to added-value. An exploration of consumers’ perceptions of improved animal welfare standards in organic production processes
Provedor de dados: 21
Autores: Marian, Livia; Krystallis Krontalis, Athanasios.
Recent studies reveal that consumers respond favourably to “organic plus” products with additional ethical attributes. The aim of the current study is to explore whether consumers would notice and value further improvements in the animal welfare standards than those imposed by the organic regulation. The results of a qualitative concept test reveal positive attitudes towards the proposed production process. The discussions about fewer standards being sufficient or about options “in-between” conventional and organic standards indicate that the difference in production processes is noticed, yet it is probably valued less than expected. The added attributes need to be thoroughly considered when developing and marketing “organic plus” products, as their effect...

Addressing the specific needs of organic farming in the New EU Member States by the Rural Development Programmes 2007-2013
Provedor de dados: 21
Autores: Slabe, Anamarija; Häring, Anna Maria; Hrabalova, Andrea.
In all New EU Member States (NMS) and Candidate Countries (CCs) there is a lack of support measures for organic farming, other than area pay-ments, and there is no coherent policy for organic farming in general. The most significant problem areas are the general policy environment, underde-veloped marketing and processing, an almost total lack of information measures, insufficient and inap-propriate organic production capacity, and a lack of training and advisory services. The latest EU regula-tion on support for rural development provides a framework for a variety of measures to assist the development of organic farming and is therefore an important instrument for policy-makers, together with national action plans for organic farming.

Administration of Silver Fir (Abies alba Mill.) to goats and its potential to control gastro-intestinal parasites
Provedor de dados: 21
Autores: Heckendorn, F.; Giebler-Schubert, F.; Walkenhorst, M.; Fertig, O.; Hamburger, M.; Potterat, O.; Valle-Zárate, A.
Gastrointestinal nematodes (GIN) substantially impact on goat health. Because of the widespread development of GIN, resistant to allopathic drugs, further research into alternative parasite control methods is required [1]. Silver fir, Abies alba MILL (SF), is traditionally used by Swiss farmers in order to control GIN infections of goats but also to improve animal welfare. A survey among goat farmers revealed that goat farmers use SF in winter during a period of approximately five months. The SF-ration per animal and day differ between approximately 8.2 g dry matter (DM) to 600 g DM [2].    As there is scientific evidence neither for an anthelmintic potential nor for the feed intake and milk performance of SF, we conducted a study with 30 goats. For a 20...

Autores: Hattam, Caroline E.; Holloway, Garth J.
Adoption of organic production and subsequent entry into the organic market is examined using Mexican avocado producers as a case study. Probit analysis of a sample of 183 small-scale (&lt;15ha) producers from Michoacán suggests that adoption is positively influenced by management and economic factors (e.g. production costs per hectare and making inputs), but also by social factors (e.g. membership of a producers’ association). Experience in agriculture has a significant but negative effect. Effective policy design must be therefore be aware of both the economic and social complexities surrounding adoption decisions.

Advances in weed management for organic cereal production in southeast Australia
Provedor de dados: 21
Autores: Burnett, Viv; Enshaw, Tim; Sutherland, Steve.
Organic cereal production in southeast Australia is challenging for producers due to a range of e of influences such as weeds and low soil available phosphorus. Two experiments were conducted on a certified organic property at Berrigan NSW during 2001-2003 to investigate ‘within crop’ weed management and forage crop management for weed control. Sowing later using a short season wheat cultivar did not affect yield and reduced (P&lt;0.05) levels of annual ryegrass (Lolium rigidum Gaud.). Incorporating a forage crop into the rotation prior to sowing a cereal resulted in improved (P&lt;0.05) weed management for the cereal crop, in comparison to retaining annual pasture. There were no differences between forage treatments in weed management in the following...

Bangladesh is one of the most densely populated countries in the world with more than 160 million people with a very small territory of 147,570 square kilometers (BBS, 2011). To ensure food production for the huge population, the term ‘green revolution’ was appeared in 1960s with the concept of ‘grow more food’. For this, introduction of High Yielding Varieties (HYV), as well as chemical fertilizers, pesticides and ground water extraction were undertaken. As a result, food self sufficiency have achieved within a very short time. At the same time, soil fertility as well as soil health maintenance totally been ignored. The use of chemical fertilizers and pesticides is increasing over the years in Bangladesh (Table 1). BARC (2001) showed that soil organic...

Afgrøde og ukrudt konkurrerer om kvælstof
Provedor de dados: 21
Autores: Petersen, J.; Eskesen, K.
Udbringningsmetoden for gylle påvirker konkurrencen mellem afgrøde og ukrudt om tilført kvælstof. Ved bredspredning af gødningen kan ukrudtet optage en betydelig del af den tilførte gødning, og dermed bliver ukrudtet en konkurrent til afgrøden. Forholdet i ukrudt/afgrøde konkurrencen om den tilførte gødning kan forskydes til afgrødens fordel ved direkte nedfældning af gødningen.    I dette års forsøg undersøges hvilken betydning afstanden mellem kornrækken og gødningsstrengen har for konkurrence mellem afgrøde og ukrudt om tilført kvælstof. Der er udvalgt en vårsæds-mark med en høj naturlig ukrudtsbestand. Den lille parcelstørrelse (30?40 cm) skyldes, at den tilførte gylle er tilsat isotopmærket kvælstof.

Aggressivität von Fusarium avenaceum, Fusarium solani f. sp pisi und Mycosphaerella pinodes auf Wintererbsen (Pisum sativum L.) unter kontrollierten Bedingungen
Provedor de dados: 21
Autores: Šišić, Adnan; Bacanovic, Jelena; Bruns, Christian; Finckh, Maria R.
Climate change scenarios exhibit a definite warming trend (Schröter et al. 2005), and it will have an impact on crop management strategies. Increase in winter precipitation and higher temperatures favour soil borne pathogens and can lead to an increase in survival rate and to more rapid population buildup (Chakraborty et al. 2000). In recent years, one of the main reasons for declining production of summer pea in organic farming in Germany are foot and root rot pathogens (Pflughöft 2008). On the other hand, predicted increase in winter temperatures is expected to favour winter pea over summer pea varieties. The hope is also, that winter peas are less susceptible to root rot as summer peas. However, few data are available. The present study was carried out...

Farmers who are interested to rear calves together with the dairy cows during the first weeks of life are confronted with problems of poor milk let-down during machine milking. Therefore it was investigated whether 3 calf-associated stimuli were capable to enhance milkability of the cows. In this contribution, the effect of the stimulations during milking on heart rate (HR) and agitation (rumination, posture of the head and behaviour during udder preparation)are presented. Olfactory (calf hair), tactile (teat massage) and acoustic(recorded calf calls)stimulation were tested on 15 dairy cows with permanent contact to their calves and 22 control cows. All cows were milked twice daily. Stimulation tests were conducted in 3 consecutive weeks during day 25–51...

Agricultural influences on carbon emissions and sequestration
Provedor de dados: 21
Autores: Ball, Andrew S; Pretty, Jules N.
This report was presented at the UK Organic Research 2002 Conference. Agricultural systems contribute to carbon emissions through several mechanisms: the direct use of fossil fuels in farm operations, the indirect use of embodied energy in inputs that are energy intensive to manufacture (e.g. fertilizers), and the cultivation of soils resulting in the loss of soil organic matter. However agriculture can also sequester carbon when organic matter accumulates in the soil or above-ground woody biomass acts as a permanent sink or is used as an energy source that substitutes for fossil fuels. The latest empirical data on agricultural carbon emissions and carbon sequestration opportunities in agricultural systems are reviewed and the necessary land use and...

Agricultural phosphorus losses and eutrophication in Nordic-Baltic countries
Provedor de dados: 21
Autores: Ekholm, Petri.
The P losses from agriculture are controlled by natural characteristics, agricultural practices and national and international agricultural as well as agri-environmental policies. To reduce the P losses the measures should be targeted at the areas and activities that are responsible for the highest actual losses of bioavailable P. The response of an aquatic ecosystem to agricultural activities is a result of complex interactions between physical, chemical and biological processes.

Agriculture and bio based economy a driver of rural transformation and livelihood?
Provedor de dados: 21
Autores: Noe, Egon.
The structures of rural communities are formed by the past development of agriculture. Industrialized agriculture does not need rural communities anymore, and are some cases even in conflict with the rural communities. The profits made by of agricultural activities have increasingly been mowed from rural to urban areas. Some sees rural development completely decoupled form agriculture; other sees bio economy as a potential revitalization of rural livelihood. This paper addresses the question under which condition agriculture and bio based economy can be a driver for revitalization for rural livelihood. This analysis is drawing on a range of different case studies of agricultural activities that have made a difference to the mainstream development. The main...

Agro forestry systems and food security among smallholder farmers of the Brazilian Amazon: A strategy for environmental global crisis
Provedor de dados: 21
Autores: Abreu, Dr. Santiago de Lucimar; Watanabe, Dr. Maria Aico.
The Amazon is known for its environmental importance for the climatic equilibrium, for its abundance and richness in biodiversity and its preservation is important to reduce global heating. Nevertheless, little research has analysed the possible positive role of the local farm population for environmental conservation. The paper investigates the possibility to conciliate the environmental conservation with the small farming expansion in the Amazon, to build agrobiodiversity, and at the same time improve food security. This social practice consequently would contribute to the reduction of deforestation and could thus falsify the old diagnosis of incriminating the poor farmers for forest and soil destruction. The study was conducted by the Associação de...

Agrobiodiversity is essential for coping with climate change
Provedor de dados: 21
Autores: Kotschi, Johannes.
Agricultural biodiversity and climate change are rarely discussed in the same context. However, there are close mutual links. Biodiversity is reduced through climate change and – at the same time – is a strategic resource for coping with its consequences: The entirety of plants, animals and microorganisms in agricultural ecosystems and their genetic diversity represent the re-source base for food.   With genetic resources gaining a new quality, present conservation approaches have to be re-vised. Instead of ex-situ conservation in gene banks a broader concept has to be envisaged which emphasises farmer conservation and is complemented by gene banks. The reason is twofold:    As future needs are unknown, a maximum of genetic resources has to be conserved at...

ABSTRACT  While classical research focuses to problem solving, design is a problem- prevention methodology, and is suitable for multi- and and interdisciplinary research teams with the vision of how to improve the agricultural sustainability. Since organic agriculture is based on the holistic approach and is also problem-prevention oriented in that it refrains from certain inputs and practices, design is an interesting methodology that could be applied more often in organic agriculture.     1. Introduction, the need to redesign agricultural systems  The demand for a more careful stewardship of a-biotic and biotic resources is central to the philosophy of sustainable development.

Agroecology and Social Sciences. In the perspectives of multidisiplinarity
Provedor de dados: 21
Autores: Noe, Egon; Alrøe, Hugo Fjelsted.
In our presentation we will focus on agroecology and the problems of sustainable agroecosystems regulation, by including a multiperspectival approach (Alrøe and Noe 2011) and a social systems theoretical perspective, based primarily on theories of Niklas Luhmann, Bruno Latour, and Charles Peirce. We will address two main challenges raised by our view on agroecology, the epistemological challenge of how to observe agroecosystems as a whole, and the ontological challenge of how to understand the existence of agroecosystems independently of perspectives.

Agroecology education and research programs are gaining prominence in universities. This emerging field provides an appropriate and convenient platform for bringing organic farming into academia. Agroecology deals with complex systems, uncertainty, and the future. Examples from organic farming and local food systems often provide valuable examples of applications of the principles of ecology in designing a sustainable agriculture. The agroecology MSc program in the NOVA network is a successful example of how organic farming can be brought into university programs, and how interdisciplinary education and research can tap into a regional faculty in agriculture.

Agroforestry Options in Northwest Vietnam
Provedor de dados: 21
Autores: Hoa, Thi Do; Whitney, Cory W.; Luedeling, Eike.
The mountainous northwest of Vietnam is home for the majority of the country’s ethnic minorities. Poverty and food insecurity are common in the region, increasing population and land scarcity have induced the expansion of agricultural areas and consequent decline of land productivity due to soil erosion and land degradation. Local farmers have begun to practice agroforestry through the introduction of high value trees into traditional cropping systems with various combinations of timber, fruit, nut forage trees and annual crops. However, because of inherent production risks and many remaining uncertainties, assessing the long-term performance of agroforestry has remained challenging. We simulated prospective system benefits of agroforestry options by...

Agronomic and economic evaluation of weed management methods in organic herb and vegetable production systems
Provedor de dados: 21
Autores: Kristiansen, Mr P; Sindel, Dr B; Jessop, Dr R.
Weed management is reported to be a major constraint in organic agriculture. Organic growers also report a lack of information about non-chemical weed control. A series of field trials was conducted in lettuce (Lactuca sativa L.) and echinacea (Echinacea purpurea (L.) Moench) crops to evaluate a range of weed control methods commonly used in organic herb and vegetable production systems. The criteria for evaluating the methods were weed growth, crop yield and cost effectiveness.    Hand weeding, tillage and organic mulches (hay and pelletised paper) were effective to very effective at suppressing weeds. In general, good weed suppression was correlated with good crop yields; however, crop yields were reduced by tillage and paper mulch. Deducting the cost of...

Agronomic and environmental factors explaining Grain Protein Content variability in organic winter wheat
Provedor de dados: 21
Autores: Casagrande, Marion; David, Christophe; Etienne, Catherine; Makowski, David; Valantin-Morison, Muriel; Jeuffroy, Marie-Hélène.
A regional agronomic diagnosis was implemented to identify factors responsible for low values of Grain Protein Content (GPC) in a network of 35 organic winter wheat fields in South-Eastern France. The influence of water nutrition, radiation and temperature, weed density at flowering, nitrogen (N) status of crop at flowering and variety type were studied. Two statistical methods were used successively: classical linear regression and a mixing model approach based on a weighted sum of all possible linear combinations of explanatory variables. GPC was significantly related to variety type, crop N status and weed density. An analysis of variance showed that weed density was related to soil type and nitrogen supply.

Agronomic options for the management of phosphorus in Australian rain-fed organic broadacre farming systems
Provedor de dados: 21
Autores: Penfold, Mr. Chris; McNeill, Dr. Ann.
The paper is an overview of strategies for agronomic management of P in organic broad-acre farming systems within the Australian rain-fed cereal/livestock belt. It concludes that to raise and maintain adequate plant-available P in these systems the importation of organic manures or composts from off-farm will be required, although the immediate issue may be access to economically viable sources.  Improving the P-use efficiency of the system by incorporating species into rotation or intercropping systems that are able to access P from less soluble sources has been a successful strategy elsewhere in the world and deserves further research effort in Australia. Agronomic management to maximise quantity and quality of pasture and crop plant residues undoubtedly...

As environmental and agronomic conditions are heterogeneous between and within locations, diversity within varieties or crop populations should increase adaptability to the changing and variable range of growing environments. The additional pressure of plant genetic diversity loss, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity and ensuring a “wider adaptation” capacity for crop varieties (Döring et al., 2011). A winter wheat (Triticum aestivum L.) CCP was created by intercrossing 20 varieties in 2001, through collaboration with the Elm Farm Research Centre and the John Innes Institute. In 2005, a seed batch of the F4 was equally...

This work suggests that Soil Surface Balance is a robust indicator to compare the performances of organic agriculture with those of conventional agriculture, even strictly following the rules of rational and optimised application of fertilisers. The results of long term nitrogen budget calculation brought us to seriously reconsider the relevance of the need to increase crop yields, and more broadly to reconsider cropping patterns and production systems. In terms of policy levers for mitigating nitrogen contamination of water resources, only the shift to organic farming provides a possible way to reconcile agricultural production and water quality.   Further, this view points out the need for specific measures to encourage more mixed farming approach to...

In 2009/2010, eight durum wheat cultivars were compared in organic and conventional cropping system in two different locations of south - central Italy. A huge dataset was evaluated, including quality and agronomic traits.   As expected, grain protein content revealed to be the real Achille’s heel for organic productions, seen as average values were not far from the Italian national standard for durum wheat minimum value of protein content (11.5 %). Anyway, values lower than expected were obtained also in conventional management. Protein quality of organically produced grain was as good as the conventional one. No Deoxynivalenol (DON) contamination was recorded in organic durum wheat even in environments where significant DON levels (although clearly lower...

The general ecological mechanisms that determine the interactions between availability of re-sources (nutrients, water) and synthesis of defence related secondary metabolites in the plants will be presented. In short, under normal conditions in nature, where growth is limited by a relatively constant availability of nitrogen at a moderate level, plants strike a balance between defence and growth. They use a fraction of resources such as carbohydrate, N and S to reach a genetically determined normal level of defence mechanisms, which will prevent or quickly overcome most types of infections. If the local availability of nitrogen happens to increase (e.g. from decomposition of animal faeces), the growth rate increases, and the balance shifts. The...

Provedor de dados: 21
Autores: Weselek, Axel; Ehmann, Andrea; Zikeli, Sabine; Lewandowski, Iris; Högy, Petra.
Agrophotovoltaik (APV) ermöglicht die simultane Produktion von Nahrungsmitteln und Strom auf derselben Fläche, indem die Solarmodule etwa sechs Meter über der landwirtschaftlichen Fläche montiert sind. In der vorliegenden Studie wurden die Auswirkungen von APV auf die ökologische Produktion von Kleegras und Winterweizen sowie verschiedene mikroklimatische Parameter untersucht. Infolge veränderter mikroklimatischer Bedingungen und einer Reduktion der photosynthetisch aktiven Strahlung, kam es zu einer Abnahme der landwirtschaftlichen Erträge.

Aim of the breeding research in LIB-SP3 and the methods to  be used
Provedor de dados: 21
Autores: Merks, Jan.
‘Low input’ pig production systems are usually characterised by smaller herd size, more space per animal, lower capital investment, often outdoor management, provision of bedding, greater labour requirement and focus on animal welfare. Examples of ‘low input’ pig production systems are “Iberico” in Spain, “Neuland” pigs in Germany, “Scharrelvarkens” in The Netherlands, “Natura Farm” in Switzerland, “Label Rouge” in France and “Freedom Food” in United Kingdom.  Organic pig production systems have similar characteristics to those described for ‘low input systems’ above. However, organic farming standards prescribe e.g. low stocking densities, access to outdoor runs, restrict the level of ‘bought in, non-organic’ feeds etc, which usually results in higher...

Against the background of a high prevalence of respiratory diseases among the workers with the housing of fattening pigs as well as conspicuous negative pulmonary results among the fattening pigs it will be necessary to determine within the framework of an interdisciplinary cooperating project the impact of and hazards for humans, animals and the environment wherever it occurred in fattening pig facilities. To achieve this research has been carried out in representative systems of housing fattening pigs especially taking into account organic systems with the use of straw in deep litter or minimal litter systems in comparison to conventional systems, where the straw was used as on occupation material. In correspondence with the current discussion in the...

Autores: Kasterine, Alexander; Bolwig, Simon.
The organic sector is addressing climate change through a number of initiatives including label-ling, and in the case of one UK certifier in 2007, a proposed restriction on organic certification for products that are airfreighted to market. The International Trade Centre and the Danish Insti-tute for International Studies examined the economic impact in Africa of banning certification for airfreighted products.   The study based on interviews with UK importers, retailers, African exporters and organic smallholders showed that a ban could have serious local economic impact in some of the poor-est rural communities in the world. A minimum of 21,500 livelihoods would be compromised. Women, youth and small producers would be hardest hit and several...

Akkumulation von Schadstoffen in europäischen Böden durch alternative Phosphordünger
Provedor de dados: 21
Autores: Weissengruber, Lina; Friedel, Jürgen K.; Möller, Kurt.
Der Vorsorgewert wurde nur von Cr überschritten. Es zeigt sich, dass das Verhältnis von Schadstoff zu Phosphor eine wichtige Rolle spielt. Von Düngern mit einem geringen P-Gehalt, wie den Komposten, muss eine größere Menge ausgebracht werden, was in dieser Berechnung zu einer höheren Schadstoffanreicherung führte. Grüngutkompost hatte das höchste Akkumulationspotenzial für alle Schwermetalle, nur bei Cadmium wurde er von Triplesuperphosphat übertroffen. Vermutlich ist die atmosphärische Schermetallbelastung von Grünschnitt in Städten und entlang von Straßen besonders hoch und konzentriert sich im Kompost. Die Schadstoffgehalte der Dünger können, je nach Ausgangssubstraten, unterschiedlich sein. Als Phosphordünger eingesetzt, hatten Struvite, Fleisch- und...

Within the EU funded project ORGAP a toolbox was developed for the evaluation of  the European as well as national action plans fror Organics food and farming. Recommendations  and a resource manual for policy makers and stakeholders were  published, based on the analysis of national Organic Action Plans as well as stakeholder  and expert consultation. The analysis showed that several EU member states  have emphasised the need to balance supply-push policies with more market-focused  demand-pull policies. An integrated approach is required through the formulation of  multi-functional Organic Action Plans (OAPs), which also adress the dual roles of  organic farming to provide public goods and satisfy consumer demand.

Autores: Baldinger, Lisa.
Common vetch (Vicia sativa L.) seeds are rich in protein and have shown stable yields under organic cultivation, but contain considerable amounts of anti-nutritional factors (ANFs). Based on reports about reducing ANFs in faba beans (Vicia faba L.) by germination, a 50:50 mixture of  erminated common vetch seeds and wheat was offered to laying hens. Voluntary intake of the germinated grains was 20% of total feed intake, which was not affected by treatment. Despite germinated grains replacing part of the laying hen feed, egg production and body weight of the hens did not differ.

Aquaculture is becoming more important for human consumption. Sustainable aquaculture procedures came up as an alternative, due to the negative environmental  impacts of conventional aquaculture procedures. Nonetheless, little is known about consumer segments for sustainable aquaculture and their preferences. Overall, participants paid a lot of attention on the declaration of origin; specifically fish products from Germany or Denmark were preferred along with local products. Consumers are  generally supporting a sustainable production. However, communication claims and labelling schemes should be improved to reach consumer acceptance.

In organic farming the ambitious claims in enhancing and keeping animal health are often not realised. The implementation of animal health plans should clear this deficit effectively. Experiences with British and Danish herd health plans showed that the acceptance of plans is an essential part for its successful transfer into practice. But anyhow, this aspect has not been regarded sufficiently. To avoid similar mistakes like done in former institution tests a social study is integrated into German projects that deal with the implementation of animal health plans in poultry, dairy, and pig hus-bandry. To get more information about the acceptance, the study requires farmers’ attitudes to herd health plans, the motivation to animal health and financial and...

Autores: Willems, H.; Kreuzer, M.; Leiber, F.
A total of 110 lambs of the breeds Engadine Sheep and Valaisian Black Nose Sheep were fattened on one lowland and three different alpine pasture types. The experiment was conducted in two consecutive years and lasted for 9 weeks of grazing in each year. Immediately afterwards, the lambs were slaughtered.  Perirenal adipose tissue and the Longissimus dorsi muscle were analysed for fatty acid composition. The lambs on the lowland pasture had the lowest proportions of linoleic and α-linolenic acid in the lipid fraction of these tissues. Additionally, there was a clear differentiation in these proportions when lambs grazed different alpine vegetation types. This was related to the content of phenolic compounds rather than the fatty acid contents of the swards,...

Altering the composition of ruminant-derived foods for improved human health
Provedor de dados: 21
Autores: Shingfield, Kevin J.; Viitala, Sirja; Leskinen, Heidi; Vilkki, Johanna.
Nutritional regulation of milk and meat fatty acid composition has been the subject of  intense research during the last few decades. Considerable progress has been made  towards understanding the role of diet on enhancing the nutritional value of ruminantderived  foods while more recent studies have attempted to elucidate the molecular  mechanisms underlying the changes in milk and tissue lipid fatty acid composition in  ruminants. Diet is the major environmental factor influencing the CLA content of  ruminant milk whilst the effects of genotype, stage of lactation and parity are  relatively minor (Palmquist el al. 2005). Concentrations of CLA in ruminant meat are  dependent on diet, gender, slaughter weight and breed with evidence of variable  enrichment...

Alternative Fütterungskonzepte für Geflügel und Schweine  im Biolandbau
Provedor de dados: 21
Autores: Früh, Barbara; Leiber, Florian; Spengler Neff, Anet; Dierauer, Hansueli.
Alternative Fütterungskonzepte für hohe Leistungen im Biolandbau sind eine Herausforderung. Kurz- und mittelfristig fokussieren die Alternativen eine Äquivalenz zur konventionellen Fütterungspraxis.  Hierfür benötigt die Schweizer Biolandwirtschaft mehr Ackerflächen, um hochwertige Eiweissfuttermittel ökologisch und nachhaltig produzieren zu können. Partiell können Nebenprodukte die Eigenversorgung erhöhen. Langfristig muss der Biolandbau aus dem konventionellen Sog der Leistungssteigerung in der Tierhaltung aussteigen. Das bedingt eigene Leistungs-, Qualitäts-, Markt- und andere Konsumentenansprüche, damit der Markt für tierische Produkte weiter an Bedeutung gewinnen kann.

Alternative Protein sources in poultry nutrition
Provedor de dados: 21
Autores: Steenfeldt, Sanna; Lübeck, Mette; Engberg, Ricarda M.
The supply of protein and essential amino acids will undoubtedly be a great challenge for European poultry nutritionists when the transition to 100% organic feed ingredients for organic poultry production becomes reality. To avoid costly and energy consuming oversea transports connected to the import of soya beans, much research effort has focussed on the exploitation of alternative locally grown protein sources to increase the sustainability of organic production systems. Besides the cultivation of protein crops like legumes (peas, lupin, and faba been) and seeds (sunflower, rapeseed), new approaches including the feeding of protein concentrates from green biomass obtained by bio-refinement are discussed. At present, many of the alternative protein...

Increasing number of stockless organic farms give reason to search for new forms of clover-grass (CG) utilization in order to maintain or increase soil fertility and productivity. A quantitative study was carried out among 93 organic farms to identify different forms of CG utilization and their assets and drawbacks on organic farms.  Different ways of CG transfer such as direct transfer (cut &amp; carry) and indirect transfer stockless farms. In addition, seven farms were interviewed about their experiences  with CG transfer practices. The farmers rate CG transfer mainly positive, since it may partially compensate the negative effects on soil fertility through the missing manure on stockless organic farms.

Autores: Parveaud, Claude-Eric; Gomez, Christelle; Chovelon, Marc; Lambion, Jérôme; Dagostin, Silvia; Pertot, Ilaria.
The objective of the UE-funded program REPCO (FP6) was to identify new alternatives to copper fungicides in organic farming. Two pathogens have been considered: grapevine downy mildew (Plasmopara viticola) and apple scab (Venturia inaequalis). Research on grapevine was carried out by GRAB (Avignon, France) and FEM-IASMA (San Michele all’Adige, Italy). Trials were carried out under natural conditions in order to test reduced doses of copper and copper-free alternatives. Five-year trials proved that copper is the best fungicide. However, the use of new low copper rate formulations and the association of copper-free alternatives with reduced doses of copper or with reduced number of copper applications (limited to the most susceptible grapevine growth stages)...

Though amaranth has been studied intensively for its exceptional nutritional properties, little has been reported about its capacity for fighting poverty, securing food supplies, turning migrations, or its impact on the environment and the prospect for improvement of living conditions of those farmers cultivating amaranth. This paper addresses possibilities and limitations that Mexican small-scale farmers are facing to enhance sustainable livelihoods in the amaranth value chain. The study reveals that amaranth, as an alternative crop and livelihood, is perhaps one of the most complete endogenous natural resources that small-scale farmers have to combat the above-mentioned problems. The study identified several local and regional barriers for increasing the...

The exclusive use of organically produced animal feedstuffs is fixed in the EU-VO 2092/91 for the year 2011. In organic farming the input of crystalline amino acids is not allowed. So the requirement of amino acids must be satisfied by the protein rich feed components. Therefore, the amino acid composition was determined in different grain legumes and some cereals. The results were compared with standard values of the literature.

Perennial weeds like Rumex spp. and Cirsium arvense are still difficult to control in organic farming systems. The presented results were part of a cooperative project within the Federal Organic Farming Scheme (BÖL) dealing with the control of perennial weeds. Aim of the project was to evaluate present strategies for controlling perennial weeds in organically managed farms and to determine new recommendations. A nation-wide survey of over 150 organic farmers in Germany showed, that ca. 30 % of the arable land is infested with the Canadian thistle (Cirsium arvense). Most of the farmers (n=140) have problems with C. arvense as well as Rumex spp. and/or Agropyron repens. The impact of soil tillage and crop rotation on controlling C. arvense in organic farming...

Ampferkontrolle mittels Heissdampfinjektion
Provedor de dados: 21
Autores: Latsch, Roy; Sauter, Joachim; Kaeser, Alexandra.
A control method for broad-leaved dock (Rumex obtusifolius) with hot steam was tested in grasslands in Switzerland. More than 700 plants were treated with a mixture of hot water and steam at a temperature of 120°C and a pressure of 30 bar. The aim was to identify an optimum heating time, so that the plant mortality rate was more than 80 %. The necessary diesel and water consumption for the heating were measured.   The success of the method is strongly related to the soil moisture. The results show, that the intended mortality rate of 80 % at a soil moisture of 30 % can be realized at a calculated heating time of 30 seconds. For this treatment 2.4 litre of water and 0.046 litre of diesel were needed.

An agronomic approach to yield comparisons between conventional and organic cropping systems
Provedor de dados: 21
Autores: Neuhoff, Daniel.
This paper discusses some relevant agronomic aspects related to the productivity of organic farming systems (OFS). In a first step some key requirements to ensure the validity of comparative studies including the consideration of rotation yields and the use of representative amounts of organic inputs are defined. A main chapter is dedicated to the potential of biological nitrogen fixation to substitute mineral nitrogen, which currently covers an estimated third of the total nitrogen input to agricultural field with increasing tendency. To bring forward OA as a sustainable method of food production with high process quality, it is suggested to focus rather on a large scale organic vegetable and fruit production than on global supply of calories and protein.

AN ALTERNATIVE APPROACH TO PLANT HEALTH: THE PROCEDURAL CONCEPT APPLIED TO COMMON BEAN SEED SYSTEMS
Provedor de dados: 21
Autores: Klaedtke, Stephanie; Stassart, Pierre; Chable, Véronique.
Pathogen-free seed is one strategy to protect plants and prevent the introduction and spread of dangerous pests.   While this strategy reduces damage to crops and delays the global spread of pathogens, it may also be regarded as an overly reductionist approach to plant health disfavoring the resilience of cropping systems. Rather than defining plant health as an objective entity, a procedural concept consisting of a set of rules for debate in order to incorporate different viewpoints on the continua between naturalist and normativist approaches, negative and positive definitions, reductionism and holism and functionality and resilience has been proposed. In the ongoing research project presented here, the questions suggested are applied to the case of...

An ancient compound rediscovered: perspectives of aphid control in organic hop growing by the use of quassia products
Provedor de dados: 21
Autores: Weihrauch, Florian; Eckert, Markus; Engelhard, Bernhard.
In the first three decades of the 20th century, quassia extract was widely used in hop growing as a chemical agent to control Phorodon humuli and other insect pests. In the first years of the 21st century this compound was rediscovered by German organic hop growers. In nine efficacy trials conducted in five field seasons, quassia products proved to be effective control agents for P. humuli in organically grown aroma cultivars. As the best method of application a systemic variant was developed by painting a suspension of quassia extract to the bines. This method proved not only to be very effective but was also best from an environmental point of view as sprayed quassia extracts had side effects on non-target organisms. As an optimal systemic application...

An Approach to Organic Plant Breeding of Cabbage and Cauliflower
Provedor de dados: 21
Autores: Chable, Dr Véronique.
Plant breeding activity has to be considered in the context of the agricultural system. The organic agriculture (OA) is more than a way of production: it is consistent with an ethics of the place and role of the man in the nature. Working for OA means to prefer a holistic approach with a ecological vision of the plant and animal in their environment to an analytic approach with a biochemical vision of the living beings.  The variety plays at least two roles in the organic way of production: (i) an ecological adaptation of the crop and the keeping of the environment equilibrium in the planting, (ii) a valorisation of products from a soil and a savoir-faire. Moreover, the breeders have to take in account the respect of the natural crossing barriers and the...

AN EVALUATION OF SELECTED SOIL PROPERTIES AND THEIR EFFECT ON THE BIOLOGICAL ACTIVITY OF SOILS IN ORGANIC FARMING IN THE CZECH REPUBLIC
Provedor de dados: 21
Autores: Sarapatka, Prof. Dr. Borivoj; Pokorny, Assoc. Prof. Ing. Eduard; Hejatkova, Ing. Kvetuse; Matlova, Ing. Vera; Krskova, Dr. Milena.
Abstract - In our research we have evaluated a series of soil indicators to determine the correlation between individual soil properties in organic farming. Regression analysis has proven that the biological activity of the soil on organically farmed areas (grasslands) as expressed by respiration is mainly influenced by the bulk density, moisture, porosity, humus content, the proportion of cation exchange capacity and total nitrogen content. The multiple regressions have proven the important dependency of basal respiration to the moisture, bulk density and total nitrogen. The supply of organic matter to the soil environment, thus greatly influences the studied soil biological activity. Similar dependences were visible in the results of both conventional...

A former study in the Danish primary schools has shown that there is an association between organic school food policies and indicators (proxies) for healthy eating among children when (school food coordinators) statements on indicators (proxies) for healthy eating are used as variable. This project continue to search for the above signs of associations but involving also a “bottom” level (pupils) perspective in addition to the “top” level (school food coordinators) in the previous study.    The project is to study the following hypothesis: organic food service praxis/policy (POP) is associated with praxis/policies for healthier eating in Danish school food service. In other words if organic procurement policies and the resulting praxis in schools can help...

An integrated study of the development of organic rice cultivation in the Camargue (France)-
Provedor de dados: 21
Autores: Mouret, J.C.; Hammond, R.; Dreyfus, F.; Desclaux, D.; Marnotte, P.; Mesléard, F.
In the Camargue, rice and durum wheat are associated in rotations that have an ambivalent ecological impact: on the one hand, these two crops contribute to the preservation of the surrounding ecosystem, while on the other hand, when cropped intensively, they can threaten the ecological equilibrium of this protected area. In this context, organic agriculture would seem to be an alternative adopted by a certain number of producers and processors. However, the pioneers of this practice encounter numerous problems, both agronomic and economic. The study presented here aims: to construct a pluridisciplinary approach to analyse the conditions of the development of organic cereal cultivation in the Camargue: to identify the principal factors that limit the...

The proposed paper takes outset in the findings of a research review on trust in management literature (Rittenhofer 2012) conducted within a transdisciplinary research project MULTI-TRUST. The paper takes outset in the following findings: there is no consensus on trust in management research; the creation and maintenance of trust is seriously underresearched; trust research on the role of culture is only emerging; trust is seriously under-theorized; an interdisciplinary conceptualization of trust is lacking. Finally, existing understandings of trust originate from 20th century philosophy and sociology that do not capture complexity, transformations and changes such as “cosmopolitanization” or ‘globalization from within’, as it relies on ‘a priori science...

An investigation into the relationship between preceding break crops and weed populations in barley crops in organic ley/arable rotations
Provedor de dados: 21
Autores: Litterick, Audrey M; Watson, Christine A; Robson, Melissa C.
This report was presented at the UK Organic Research 2002 Conference. The relationship between weed populations and cereal crops following nine organic break crops was investigated in field trials in Warwickshire, Aberdeenshire and Ceredigion in 2001. Weed biodiversity was high on all sites and varied between sites in terms of species present. Severity of weed infestation differed significantly between sites and between cereals following different break crops. The impact of break crop species on the incidence and severity of the weed burden in the following cereal is discussed in relation to the field trials at the three sites.

AN ORGANIC AGRICULTURE MODEL FOR TURKEY
Provedor de dados: 21
Autores: Aslan, Bulut; Demir, A. Yonca.
Organic farming presents a solution to socio-economic, environmental and health problems caused by conventional food production methods. In this paper, we propose a linear programming model to plan Turkey’s organic food production. Specifically, we want to find how many hectares of each food type should be planted in each municipality of Turkey so that the whole population consumes organic foods only. The model incorporates transportation between regions while identifying any missing or excess foods. We also describe the data requirements of the model and discuss data availability. Results on an aggregate (small) model are promising.

An Overview of Phytosanitary Risk Aspects of Composting by Organic Farmers
Provedor de dados: 21
Autores: Termorshuizen, Aad J.; Blok, Wim J.
Usage of compost in agriculture always brings about the risk of introducing plant pathogens. By proper composting, resulting in high temperatures during the thermophilic phase, compost can be applied safely. Organic farmers often prefer to compost organic residues themselves. The advantage of such an approach is that no material of foreign origin is introduced, but a drawback is the smaller scale of composting, which brings about greater phytosanitary risks. These risks can be dealt with by increasing the composting duration and by proper turning of the compost heap. If only organic residues from farms are composted, this usually results in low-quality composts because of the low lignin contents. Therefore, addition of materials that are high in lignin,...

An overview on the role and potential of forage production on lowland organic livestock farms
Provedor de dados: 21
Autores: Weller, Richard F; Jones, Evan L.
This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).  This paper outlines some of the factors influencing the level of forage production on organic lowland farms. Optimal forage production is achieved by maintaining soil fertility, providing a balance between N-fixing and N-demanding crops and producing sufficient quantities of quality feed to meet the requirements of the organic livestock enterprise. A key objective for organic systems is to increase the efficiency of forage production by improving the nutrient input/output balance of the wholefarm system. Improving forage quality reduces the requirement for external feed sources, leading to increased self-sufficiency in the wholefarm system....

Anaerobic digestion as a tool to eliminate animal parasites and weed seeds
Provedor de dados: 21
Autores: Johansen, Anders; Hansen, Christian M.; Andreasen, Christian; Carlsgart, Josefine; Nielsen, Henrik Bangsø; Roepstorff, Allan.
Anaerobic digestion of residual materials from animals and  crops offers an opportunity to simultaneously produce bioenergy and plant fertilizers at single farms and in farm communities where input substrate materials and resulting digested residues are shared among member farms. A surplus benefit from this praxis may be the suppressing of propagules from harmful biological pest like animal parasites, pathogens, and weed seeds. In the BIOCONCENS project (http://www.icrofs.dk/Sider/Forskning/foejoIII_bioconcens.html) batch experiments were performed, where survival of six species of weeds and the pigs large roundworm Ascaris suum (non-embryonated eggs) was assessed under conditions similar to biogas plants managed at meso- (37°C) and thermophilic (50°C)...

Anaerobic digestion for closing the loop of a biorefinery for organic farming: Production of biogas and organic fertilizer from process residues
Provedor de dados: 21
Autores: Fernandez, Maria Santamaria; Ytting, Nanna Karkov; Lübeck, Mette; Uellendahl, Hinrich.
The availability of organic animal feed for monogastric animals and organic fertilizer is in many regions a limiting factor for the further spread of animal breeding and crop cultivation in organic farming. The production of these two commodities is the main target of a green biorefinery concept based on regionally organically grown grass biomass, called Organofinery. Anaerobic digestion of the residual streams after protein separation for the organic feed product is a key process to extract both the energetic and the nutritional value of the residual biomass in the biorefinery. Biogas potentials of the residual streams from the processing of red clover and clover grass (press cake obtained from screw pressing to produce green juice and brown juice after...

Anaerobic digestion of manure - consequences for plant production
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Johansen, A.; Pommeresche, R.; Riley, H.
Organic farming systems are today dependent upon fossil energy. Another challenge are soil nutrient concentrations, which may be depleted with time even in animal husbandry systems (Løes &amp; Øgaard 2001). Anaerobic digestion (AD) of animal manure may produce biogas to replace fossil fuels, and reduce methane (CH4) emissions during manure storage. Co-digestion of substrates rich in energy increases the economic viability of the biogas plant, and off-farm substrates such as fish silage or household waste may add nutrients to the farming system. AD may also ease manure handling, while reducing the amount of weed seeds and animal pathogens. A reduced proportion of easily degraded C in the AD-manure may however impact the soil fauna/microflora and humus...

Organic Agriculture is especially affected by the increasing spread of stem rust in rye (Puccinia graminis f. sp. secalis) because there is a lack of resistant cultivars in Germany. To analyze the virulence situation of rye stem rust, 71 single-pustule-isolates were established and 30 of those were tested with a differential set consisting of 19 lines. The isolates could be classified into 22 different pathotypes. Only seven pathotypes could be found more than once. Most of the isolates showed a complexity of five virulences. In a preliminary analysis a Simpson index of 0,98 was found indicating a high level of diversity of German stem rust populations. Nine of 19 tested lines reacted fully resistant in seedling stage. In 2011, 70 and 30 rye populations,...

Analyse des Energieeinsatzes und der Energieeffizienz bei der Futtererzeugung in der Milchviehhaltung
Provedor de dados: 21
Autores: Frank, Helmut; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
Fodder production requires the highest energy input in dairy farming. Taking the  organic and conventional dairy farms from the project “climate effects of land use systems – evaluations on pilot farms” as an example we analyse the energy input for producing different fodder types and the influence of feeding strategies in Southern Germany. The results show that grazing is the most energy efficient form of feeding, followed by fresh grass and silage. Hay requires the highest energy input per unit forage energy. Maize silage has a lower energy input due to high yields. The higher the part of roughage in the ration the lower is the energy input for production of the ration.

An optimal supply of dairy cows with energy and nutritive substances is just as important for the organic as it is for the conventional milk production. The current project examined if in organic rural economy the feeding meets the required demand. In the trial period from 10 Nov. 2001 till 17 Oct.2003 data of the milk performance test were gathered for 11 capacity control days. The energy and nutritive substance made a silage food capacity of 17 -24 kg milk per cow and day possible, so a milk capacity of 8157 kg milk per cow and year could be realized. A suspected shortage of nitrogen based on the low milk urea concentration caused by the normal milk protein concentration could not be confirmed. The result of the capacity control showed that only     76 %...

The aim of this study is to analyze alternative options of a Common Agricultural Policy  (CAP) after 2013 and their consequences for farms in Austria. Projections about the  development of agricultural markets are based on OECD-FAO forecasts. Using these  price projections, three alternative policy scenarios have been developed for a period  beyond 2013, which are compared with a baseline scenario. The three policy scenarios  encompass different assumptions on specific measures in the dairy sector and  higher modulation (13% versus the existing rate of 5%) as well as budget cuts in the  first pillar of CAP of 30% and 50%, respectively. All the scenarios have been analyzed  with the farm optimization system FAMOS, which differentiates among 5.796 typical...

The objective of this paper is to analyse and define the field conditions close to the crop plants of sugar beet (Beta vulgaris L.). The aim is to use this study for the choice and development of new physical weeding methods to target weeds at individual plant scale level. It was found that the close to crop area is like a ring structure, comprising an area between an inner- and outer-circle around the sugar beet seedling. Physical weeding should not be applied to the area within the inner circle.  The radius of the inner circle increases with the appearance of young beet leaves during the growth season. It was also found, that no weeds were germinating within 1 cm around individual sugar beet seedlings. Therefore this distance should be added to the...

Differences between the EU Regulation (EEC) 2092/91 and selected private as well as governmental organic standards were analysed as part of an EU-funded research project on the revision of this regulation. Most of the differences were found in the following areas: conversion, fertilising, animal feeding, veterinary treatment and animal husbandry. Many differences have specific justifications, influenced by specific national or regional circumstances or policy framework. The variations between the EU Regulation, governmental and private-sector standards do not concern basic requirements; i.e. there is a general agreement on the main general principles of organic agriculture within the EU. A certain regional flexibility can be justified.

Autores: KAZIMIERCZAK, RENATA; JABŁOŃSKA , PAULINA; REMBIAŁKOWSKA, EWA.
Organic food is produced in accordance with strictly defined rules, established by the European Union legislation. Thanks to this is considered to be safer and healthier than produced conventionally. Many studies show that organic products, especially vegetables, fruits and preserves contained more dry matter, vitamin C, vitamin B group, total sugar, indispensable amino acids and mineral compounds. At the same time organic plant products usually have been in general better evaluated in terms of taste and smell than conventional food. The aim of this study was to analyze the assortment of beetroot juice from organic and conventional stores in Warsaw, Poland and consumer sensory evaluation of selected products.

Analysis of regulatory framework and standards applied to organic wine-making in Europe
Provedor de dados: 21
Autores: Jonis, Monique; Monnier, Marie Christine; Micheloni, Cristina; Schmid, Otto; Hoffman, Uwe.
Because wines (of grapes) were excluded from the scope of EC Regulation 2092/91 (annex 6, concerning processing organic food, does not apply to wine) concerning organic farming, up till now there is no legal definition for organic wines at European level, but only rules for organic grapes production. This project: ORWINE, is aiming to help the UE commission to develop a legislative framework for the transformation of organic grapes into organic wine. This would allow replacing the current definition “wine made from organically grown grapes” by “organic wines”. One of the first tasks of this project is a description of the regulatory framework applied to EU organic wine-making. Legal public and private standards for wine processing are taken in...

Downy mildew is one of the most important grape diseases world-wide. The pathogen is a genetically highly diversified organism with a high capacity of adaptation. A monitoring of changes in population structure of P. viticola subjected to new copper replacing products or strategies, studied and developed within REPCO (Replacement of Copper Fungicides in Organic Production of Grapevine and Apple in Europe) is important for assessing selection pressure which could lead to a reduction of efficacy of these new measures. Therefore P. viticola lesions collected on untreated and treated vines were analyzed by means of microsatellite markers. No significant differences in the populations structure were determined among untreated and treated populations, indicating...

Autores: Simeone, F.C.; van Ruth, Saskia.
A growing consumers’ awareness of human health’s risks, environmental fragility, and animal welfare has boosted organic production of foods. Due to their high production costs, however, organic products tend to retail at a higher prices than their non-organic counterparts. This premium price exposes organic products to fraud and counterfeiting, which, in addition to administrative controls, call for confirmatory assessments of the organic identity. Authentication of organic products is a complex task, which requires the identification, quantification, and distribution analysis of multiple compounds which are considered discriminators (i.e., fingerprints) between organic and non-organic products. Unlike conventional analytical methods, in fact, identifying,...

Rural development in China has been a huge success: from hunger to self-sufficiency to food donor in only a few decades. This fast growth of agricultural production, however, came at a cost – which consequently stresses the natural resources, pollutes environment and increases income inequality between poor and rich. Now, Chinese authorities seek other ways than conventional agriculture to continue high productivity, but without causing degradation of natural resources and environment to fulfil the needs for safe nutrition of a growing society.   Ecological or organic agriculture is suggested to be a modern and promising alternative that has a sound record of adapting food safety and natural harmony.  Within this context, the main questions of this...

Anbau der Blauen Lupine (Lupinus angustifolius) mit  unterschiedlichen Reihenabständen und Bewertung der  Futterqualität mittels NIRS
Provedor de dados: 21
Autores: Böhm, Herwart; Aulrich, Karen.
Blue lupins have become more important in animal feeding due to increasing organic  animal husbandry. They have a low starch content, a high protein content and the best  protein quality of the home-grown grain legumes. The feed quality of blue lupins can  be analysed by NIRS very quickly and cost-efficiently. Weed infestation in pure stands  of blue lupin is often a problem. Mixed cropping systems are a good alternative for  weed suppression, but the yield percentage of blue lupins in mixed cultivation is low.  Weed infestation can be reduced by hoeing. Therefore the cultivation of blue lupins  with the possibility of hoeing in the wider row distances (25.0 cm, 37.5 cm), were  compared to 12.5 cm row distance (only currying).

Two varieties of peas and two species of cereals have been tested sole and inter-cropped during three years with respect to yield and weed competition on a fruitful soil in saxony. A randomized complete block design with four replications was used. Yield of grain was highest with sole cropped spring wheat and lowest with a variety of pea. Intercropping of peas with wheat or barley did not increase total grain yield signifi-cantly compared to the pure stands of cereals. In mixed crops grain yield of pea seed was low at harvest and weed competition was only slightly enhanced. Nitrogen yield was highest with sole cropped peas.

Mischanbausysteme bieten aufgrund ihrer höheren Biodiversität auch eine höhere Pufferkapazität gegen biotischen und abiotischen Stress und weisen durch gute Ausnutzung von Standraum und Standebene eine höhere Konkurrenzkraft gegen Unkraut auf als Reinanbausysteme. Zudem kommt es zu Synergismen bei der Nährstoffaufnahme und bei der Standfestigkeit (Aufhammer, 1999; Rauber, 2001). Besonders in Systemen mit limitiertem Betriebsmittelinput, wie dem ökologischen Landbau sind diese Bestandseigenschaften interessant. Die Koppelproduktion einer Ölsaat, z.

Anbau von Raps mit Kleeuntersaat im ökologischen Landbau
Provedor de dados: 21
Autores: Paulsen, Hans Marten; Böhm, Herwart; Stuckert, Peter; Ulverich, Jürgen.
Im ökologischen Landbau ist der Anbau von Raps aufgrund des Schädlingsbefalls mit einem hohen Risiko behaftet (Petterson et. al. 2002; Haas u. Kramer, 1995). Weiterhin stellt Raps als stark stickstoff- (N) -zehrende Kultur hohe Ansprüche an die Vorfrucht und an die organische Düngung (Gruber, 2001; Mayer et. al., 2001; Loges u. Böhm, 2001). Er konkurriert aus diesem Grund im ökologischen Landbau mit Weizen um den Platz in der Fruchtfolge. Für die N-Versorgung der Nachfrucht erscheint es daher günstig, im Raps eine Kleeuntersaat zu etablieren. Es wurden verschiedene Verfahren des Rapsanbaus erprobt.    Eine Weisskleeuntersaat zwischen den Reihen trug im ersten Versuchsjahr weder meßbar zu einer Verbesserung der N-Versorgung von Winterraps bei, noch konnte...

Der Anbau von Wintererbsen wird seit eingen Jahren als Alternative zum Anbau der Sommerformen diskutiert. Die derzeitig verfügbareb Sorten sind durch sehr unterschiedliche Wuchstypen chrakterisiert. Empfehlungen für die Sortenwahl werden für unterschiedliche Standortbedingungen benötigt. Das Thünen-Institut für Ökologischen Landbau führt seit 2012/13 Sortenversuche durch, abhängig vom Wuchstyp in Reinsaat und/oder Gemengeanbau. Die Ergebnisse von zwei Anbaujahren zeigen, dass nur wenige Sorten eine ausreichende Winterhärte aufweisen. Normalblättrige Sorten benötigen einen Partner, um die Standfestigkeit hinsichtlich einer guten Beerntbarkeit zu erhöhen. Beide Wuchstypen, halbblattlose und normalblättrige Sorten haben das Potential für hohe Erträge.

In einem zweijährigen Feldversuch, auf je vier bayerischen Standorten, wurden daher drei alte Braugersten im Vergleich zu dem aktuellen Braugerstensortiment hinsichtlich ihrer Anbaueignung für den ökologischen Landbau geprüft.  Alle modernen Sortenerzielten im Vergleich zu den drei alten Sorten mit einer Ausnahme höhere Erträge und zeichneten sich durch wesentlich bessere Brauqualitäten aus. Zwar wiesen zwei der drei alten Sorten die im ökologischen Landbau gewünschten Eigenschaften einer größeren Pflanzenlänge und höher Massenbildung in der Anfangsentwicklung als die modernen Braugersten auf: ein geringerer...

Because of the interdiction of chemical seed treatment, smut resistance is a main demand for cultivation of winter barley in organic farming. A comparison of common high yielding varieties with those chosen particularly with regard to good smut-resistance or tolerance showed no significant differences in field performance under the conditions of organic farming. Main criteria were the yield of grain and the content of protein and most important amino acids for animal nutrition (Cystine, Lysine, Me-thionine, Threonine, Tryptophan). Besides this the degree of shading weeds was estimated by means of measuring leaf areas and lengths of stalks. The leaf area proved to be the main factor. The availability of smut resistant or tolerant varieties out of organic...

Autores: Kautz, Dr. Timo; Köpke, Prof. Dr. Ulrich.
The aim of this study was to gain experience in the organic cultivation of artichokes  (Cynara scolymus L.) under the condition of the temperate climate of the Lower Rhine  Bay. The effects of reducing the number of buds by removing bastard branches on the  yield of two cultivars were tested in a field experiment. Cultivar ‘Imperial Star’ yielded  up to 10.31 t FM / ha, for cultivar ‘JW 109’ the yield was up to 7.63 t FM / ha. In both  cultivars, removing bastard branches resulted in higher bud weight, whereas total yield  per ha was reduced.

Autores: Pommer, G.
Crop rotations of organic farms without livestock were compared on three sites for three years in three replications. The crop rotations consisted of a kernel legume and two cereals. Different distances in the rows of kernel legumes and various ways of intercropping after them should improve the yield of cereals. Within the kernel legumes peas (5.5 tons/ha) and faba beans (5.2 tons/ha) had high, lupins (2.5 tons/ha) low yields. The following crop winter wheat reached high yields (6.0 tons/ha) with no differences depending on the species of kernel legumes, their distances in rows or the variations in intercropping. The same occured with winter rye but on much lower yield level (4.0 tons/ha). It was not possible to improve the yield of cereals through...

Cropping spring barley, long varieties with vigorous growth are desired in organic farming expecting better regulation of weeds. Six old varieties were compared to three modern varieties in a field trial during 2010 and 2011 nearby Freising, Bavaria. The modern varieties were the recommended varieties for Bavaria at beginning of the trial. Higher crop yields were determined for modern varieties with limitation for one of these varieties. The malt quality of the modern varieties was considerably better than for the old varieties. Vigorous growth and plant length was higher for all and for five of the six old in comparison to modern varieties, respectively. But no differences in weed pressure could be measured due to successful mechanical weed control....

Agriculture and biodiversity are closely connected. Especially the soil ecosystem is crucial in this relation. Earthworms are seen as good indicators for the health and functioning of the soil. Beneath different biodiversity measurese earthworm ecological group data is analysed to assess soil biodiversity, fertility and capability to deliver ecosystem services. However this kind of data is compositional and needs a special statistical treatment. New available methods for this purpose were applied to data from the BIOBIO project (www.biobio-indicator.org) to gain better understanding of the complex relationship between earthworms, agricultural management and environment.

Potato is affected by numerous diseases. Among those diseases, late blight (Phytophthora infestans) and rhizoctonia (Rhizoctonia solani) have a strong economic impact. Organic farming doesn’t have efficient protection products to control those diseases and to guarantee yield and production quality. Furthermore, we observe that organic food chain propose the same cultivars as the traditional food chain and those cultivars are generally susceptible to late blight. Regarding to the trials managed to propose new cultivars to Swiss cultivars recommendation list, there are numerous new cultivars with interesting resistance profile. Among 141 cultivars tested, 30 could be proposed to the organic food chain. Indeed, those cultivars are less susceptible to late...

Autores: Reents, Dr. H. J.; Egerer, Johanna; Hermann, A.
Green manure legumes are a necessary element of organic crop rotations. However,  they are able to propagate nematodes especially Meloidogyne and Paratylenchus  species. The results of a pot experiment showed that plant species of the genera  Pisum, Vicia, Trifolium had a higher propagation rate of Meloidogyne hapla than salad  Latuca sativa while plant species of the genera Medicago and Melilotus were less  susceptible to infestation of nematodes. It is concluded that crop rotation management  especially in vegetable production has to consider the different susceptibility of the  legumes and further research has to test more species and varieties.

Ziel der Untersuchung war es, Informationen über Biobetriebe mit Pferdeangeboten zu gewinnen. Hierzu wurden Fragebögen von 58 Betrieben aus ganz Deutschland ausgewertet. 12 dieser Betriebe lieferten zusätzliche ökonomische Kenndaten. Die 58 Betriebe waren im Durchschnitt 66 ha groß, insgesamt wurden 1.670 Pferde gehalten. 49 Betriebe hielten Pensionspferde, 37 machten Reitangebote mit eigenen Pferden (28 Betriebe Kombinationen). Die Pferdehaltung trug zur Hälfte des landwirtschaftlichen Einkommens bei. Die Deckungsbeiträge je Pferd waren höher bei den Reiterhöfen als bei den Pensionsbetrieben (262 vs. 163 € im Monat). Insgesamt scheint die Pferdehaltung eine interessante Einkommensalternative für Biobetriebe zu sein.

Although the demand for organic products in Germany continues to increase, there is  still a gap in supplied quantities. This issue is also valid for organic potatoes. The  paper presents an estimate of the price elasticity of supply for organic potatoes in  Germany using a Nerlovian model, where the output is a function of expected price,  output in terms of area adjustment and further exogenous variables. The results indicate  a short-run elasticity of 0.22, suggesting that organic potato farmers are highly  unresponsive to price changes on a temporary basis. However, in the long-run farmers  react highly responsive to price changes with an elasticity of 1.86. It shows that  price incentives can be effective in promoting organic potato production,...

Animal dietary intervention study of effect of organic vs conventional food production methods on health and well – being of rats
Provedor de dados: 21
Autores: Rembiałkowska, prof. Ewa.
According to the research studies conducted during last 20 years the wholesomeness and nutritive value of the organically produced crops is often higher than of conventional plant products. Organic crops contain less harmful substances (e.g. pesticide residues, nitrates) and more desirable compounds (e.g. vitamin C, flavonoids) than conventional ones.      However, the impact of the organic food consumption on animal and human health and well being still remains almost unknown. Small experimental mammals fed organically showed in some experiments better health and fertility parameters, but much more research studies are needed in order to broaden our knowledge.     Therefore a dietary intervention study on rats will be conducted at Warsaw Agricultural...

Animal manure for biogas production - what happens to the soil?
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Johansen , Anders; Pommeresche, Reidun; Riley, Hugh.
Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. This is of concern because organic matter in the slurry is converted to methane, which escapes the on-farm carbon cycle. In 2010, a study of this question was initiated on the organic research farm in Tingvoll, Norway. So far, a biogas plant has been built, producing anaerobically digested slurry to be compared with undigested slurry in perennial ley and arable crops. Effects on crop yields, soil fauna, microbial communities, soil structure, organic matter and nutrient concentrations are measured.

Animal welfare and food safety: danger, risk and the distribution of responsibility
Provedor de dados: 21
Autores: Kijlstra, Prof.Dr. Aize; Bos, Dr. Bram.
Increased animal welfare may pose risks for public health, such as increased bacterial, viral or parasitic infections or an increased level of environmental contaminants in the food product. Examples include Campylobacter in organic boilers, Toxoplasma in pigs and poultry meat and Mycobacterium paratuberculosis in milk. Concerning environmental contaminants it is known that free-foraging laying hens will produce eggs that contain higher dioxin levels than hens kept in cages. Furthermore, outdoor chickens are considered to play an important role in the case of Avian flu outbreaks. This review indicates that it is possible to tackle each of the issues mentioned. Risk management is not only a responsibility of the government, but also should be divided...

This study aimed to investigate self-establishment potential, ability of biological nitrogen fixation (BNF), of seven annual self-reseeding legumes and their short–term pre-crop effect on succeeding zucchini and lettuce crops. Results are presented from field experiment in Apulia region, South of Italy, where the self-reseeding legumes were screened during two cropping cycles.  For the first cropping cycle (2005-2006) preliminary results suggested that Trifolium spp. performed better than Medicago spp. Among the seven species, five were more suitable to the site’s conditions.  T. angustifolium and M. polymorpha gave the best results. T. angustifolium...

Autores: Al-Bitar, Lina; Wehbé, Elias; Ayoub, Mohamed; Jamea, Mostafa.
Biological Nitrogen fixation (BNF) should be the most important means for N supply in organic agriculture. This study aimed at assessing the effect of fifteen legume cultivars on subsequent crops in three consecutive growing seasons to identify the most efficient and suitable ones as building crops in rotation programs under Mediterranean environment. T. subterraneum cv. York and T. glanduliferum cv. Prima, induced the best effects on wheat, particularly on total biomass, number of grains, dry matter production and increased yield by 670% and 567% respectively more than the control.

Autores: Weedon, Odette; Lanvers, J.; Wersebeckmann, V.; Purwien, T.; Heinrich, Sven; Finckh, Maria R.
Evolutionary breeding through the introduction of composite cross populations (CCPs)encourages intra-specific diversity and increases diversity in the agricultural landscape. Increased genetic diversity in crops may help to buffer both biotic and abiotic stresses and will play an increasingly important role in unpredictable climatic conditions become more unpredictable (Østergård et al. 2009). A number of CC winter wheat populations, commercial varieties and CCP line selections were tested at the University of Kassel, under differing N input levels in order to test past adaptation and suitability to differing fertilisation levels. The CCPs have been managed since 2005 under both organic and conventional conditions without conscious selection.  Genetically...

Provedor de dados: 21
Autores: Hoffmann, Lena; Hörning, Bernhard; Barth, Kerstin.
Ziel der Studie war die Erhebung von Erfahrungen aus der Praxis mit muttergebundener Aufzucht bei Milchschafen. Es wurden 11 Leitfadengestützte Experteninterviews geführt. Die Betriebe unterschieden sich in ihren Aufzuchtmethoden vor allem durch Beginn des Melkens (Spanne 1. - 56. Tag nach der Geburt), Anzahl Melkungen am Tag (1 oder 2), Dauer des Kontakts zwischen Mutterschafen und Lämmern (ganz- oder halbtags), sowie der Dauer der Säugeperiode (45 - 183 Tage), bei z.T. sehr unterschiedlichen Kombinationen. Die Betriebsleiter waren trotz der reduzierten Milchmenge zufrieden mit ihren Aufzuchtmethoden.

Auf Grundlage von Interviews mit 16 laufenden Projekten im deutschsprachigen Raum sowie der Literatur wird ein Überblick über Alternativen für die ökologische Geflügelzucht gegeben. Bisherige Feldprüfungen von Hybridherkünften ergaben keine optimale Herkunft. Eine Zucht spezieller Ökohybriden durch die Zuchtunternehmen erscheint mittelfristig unrealistisch. Die Leistungen von Rassehühnern können gesteigert werden durch Selektion innerhalb der Rasse oder durch Kreuzungen (mit anderen Rasse- oder mit Hybridhühnern). Im Beitrag werden jeweils entsprechende Beispiele vorgestellt.

Ansätze zur Landschaftsentwicklung durch Landwirtschaft – das Beispiel Marbachstal/ Kassel
Provedor de dados: 21
Autores: van Elsen, Thomas.
As a diverse landscape is no longer automatically produced by agriculture, the development of landscape may become a new challenge for organic farms, and for the integration of agriculture and nature development, too. The perception of the landscape can be the basis to create a process of landscape development instead of carrying out a single landscape plan. The example of a newly founded organic landscape and gardening farm in the Marbach Valley (Kassel) describes the first steps how to develop a dialogue between people from outside the farm (people engaged in nature conservation, local authorities), the farmer and the landscape. Two seminars were carried out as a first encounter – a social process in order to appreciate values of landscape and nature,...

Die anhaltende Gefährdung zahlreicher Arten der Segetalflora ist in Deutschland gut dokumentiert. Neben Schutzbemühungen gibt es neuerdings auch Überlegungen und Initiativen zur Ansiedlung gefährdeter Ackerwildkräuter. Flächen mit ökologischem Getreidebau eignen sich hierfür aufgrund reduzierter Stickstoffdüngung und des Verzichts auf Unkrautvernichtungsmittel grundsätzlich. Von 2007 bis 2011 wurde auf einer Fläche eines Bio-Betriebs auf dem südlichen Frankenjura ein Tastversuch zur Wiederansiedlung von sieben gefährdeten Segetalarten durchgeführt. Der Zusammenhang zwischen Keimraten im Labor und der Etablierung im Feld war gering und von Art zu Art verschieden.

Autores: Katakam, KIran Kumar; Thapa, Sundar; Meyling, Nicholai V.; Dalsgaard, Anders; Roepstorff, Allan; Thamsborg, Stig Milan.
The rising demand for pigs produced in organic farming systems, which require access to outdoor areas and associated increased risk of gastrointestinal nematode infections, is creating growing interest in alternative control strategies. Also development of anthelminthic resistance due to extensive use of anthelmintics is a concern in intensive pig production. Use of chitin-degrading microfungi is one of the options. Extensive research has been conducted on biological control of plant pathogenic nematodes using such fungi, and some fungal species are commercially available for plant protection. In contrast, there are only limited laboratory studies conducted on eggs from nematodes which are animal parasites. The aim of present study is to investigate the...

The maintenance of a beneficial bacteria balance in the gut is important to increase the animal’s resistance to diseases. Nitrite may kill gut pathogens representing a non-immune defence mechanism. Nitrite can be derived from dietary nitrate that is reduced under the acidic conditions of the oral cavity.   An in vivo study was designed in order to establish the antimicrobial effects of dietary nitrate on the gut microbiota and on the health of 96 weaning piglets. The pigs were fed a diet containing high levels of nitrate (15 mg/kg feed and 150 mg/kg feed) and then challenged with Salmonella enterica serovar typhimurium. Changes of the intestinal microbiota composition were assessed by analysing the stomach and jejunum contents from all the pigs.   Results...

Anvendelse af falsk såbed, blindharvning og flammebehandling i højværdiafgrøder
Provedor de dados: 21
Autores: Melander, Senior scientist Bo.
På baggrund af nærværende undersøgelse med såløg har det ikke været muligt at påvise væsentlige forskelle mellem blindharvning og flammebehandling anvendt 1-2 dage før løgenes fremspiring. Da blindharvning er en betydelig billigere og mere miljøvenlig metode end flammebehandling, vil det være relevant yderligere at undersøge mulighederne for at anvende blindharvning i højværdiafgrøder.    Undersøgelserne viste også, at tidspunktet for blindharvning godt kan foregå 4-6 dage før fremspiring frem for 1-2 dage før, uden at effekterne mod ukrudt derved svækkes væsentligt. Tidligere blindharvning kan være ønskeligt i øverligt såede kulturer som såløg og -porre for at mindske risikoen for at skade kulturfrøenes kimstængler.     Falsk såbed anvendt i såløg havde...

I enfaktorielle forsøg anvendes oftest metoder, som sikrer, at alle par af forsøgsled kan sammenlignes med den samme (og bedst mulige) sikkerhed, mens man i flerfaktorielle forsøg oftest anvender metoder, som sikrer, at de mest interessante effekter (hoved- og/eller vekselvirkninger) kan estimeres bedst muligt. Artiklen viser tre eksempler på anvendelse af ufuldstændige blokforsøg: 1) Sortsforsøg i ærter (enfaktoriel), 2) Frøavlsforsøg med strandsvingel...

Anwendung einer an Möhren und Weizen standardisierten Biokristallisation  auf Äpfel und Aloe vera
Provedor de dados: 21
Autores: Kahl, J.; Busscher, N.; Mergardt, G.; Ploeger, A.
The biocrystallization method was standardised on carrot and wheat. With the standardised  method samples from different farming systems could be successfully discriminated.  For this paper, we investigated to what degree the standardised method  can be adapted to other product classes like apples or Aloe vera. We found, that the  sample preparation procedures must be developed for each new product whereas the  conditions for the steps evaporation and crystallization as well as the evaluation of the  patterns could be directly transferred. The variability as well as the factors of influence  could be compared to those found on carrot and wheat samples.

Autores: Witten, Stephanie; Ritteser, Carolin; Grashorn, Michael; Aulrich, Karen.
Knowledge of the precaecal (pc) crude protein (CP) and amino acid (AA) digestibility can be used in formulation of poultry diets. The pc CP and AA digestibility can differ between various feedstuffs as well as between batches of the same feedstuff. Thus, table values can provide misleading information. However, they are generally used because there is no standard method to predict the actual pc CP and AA digestibility. Thus, the aim of the study was to evaluate the use of an in vitro multi-enzyme assay to predict the pc digestibility of CP and AA in broiler chicken.  The adapted in vitro multi-enzyme assay provides good estimates for the pc CP and AA digestibility of single feedstuffs for broiler chicken. Further calibrations with in vivo results are...

Der Ökologische Landbau bietet große Chancen für den Schutz und die Erhöhung der Biodiversität. Im Rahmen des Pilotprojektes "Landwirtschaft für die Artenvielfalt" wurde ein neuer Naturschutzstandard entwickelt, der auch für Vermarktungszwecke genutzt werden kann. Die meisten Betriebe erreichten den Naturschutzstandard auf Grundlage ihrer praxisüblichen Bewirtschaftung inkl. der Umsetzung konkreter Naturschutzmaßnahmen, die sie aus rund 70 Maßnahmenvarianten wählen können. Defizite traten bei den kleinräumig effektiven Maßnahmen auf. Durch eine naturschutzfachliche Beratung werden die Akzeptanz bei den Landwirten und die Wirksamkeit für die biologische Vielfalt verbessert.

Apfelschorfbekämpfung 2001 unter besonderer Berücksichtigung der Berostung
Provedor de dados: 21
Autores: Zimmer, Jürgen.
Im Jahr 2000 konnte überall eine sehr starke Berostung an 'Elstar', 'Jonagold' und anderen Apfelsorten festgestellt werden. Die starke Qualitätsminderung durch Berostung trat jedoch nicht nur in der ökologischern Apfelproduktion sondern auch bei integriert wirtschaftenden Obstbaubetrieben auf. Bei der Ursachensuche wurde häufig Schwefelkalk im Zusammenhang mit Berostung erwähnt. Die Erfahrungen mit Schwefelkalk, die in vielen Versuchen an der Staatlichen lehr- und Versuchsanstalt Ahrweiler gewonnen wurden, deuteten jedoch nicht auf ein starkes Berostungspotential des Schwefelkalkes hin. Jedoch ist der pH-Wert von Schwefelkalk sehr hoch und liegt bei einem Wert von über 12. Alkalische Spritzbrüher werden im Allgemeinen als berostungsfördernd betrachtet. Um...

Autores: Gutzwiller, Andreas; Stoll, Peter.
Fusarium head blight and the contamination of cereals with the Fusarium toxins deoxynivalenol (DON) and zearalenone is more prevalent when fields are not tilled in order to conserve the soil structure. DON impairs the feed intake and the growth rate of young pigs, whereas both, DON and zearalenone affect the fertility of sows. In two feeding trials using a total of 220 weaner pigs the hypothesis was tested that apple pomace alleviates the negative effects of Fusarium toxins. The two experiments had a 2 x 2 factorial design: Fusarium contaminated and uncontaminated wheat, and 8 % apple pomace and no pomace in the diet. In both trials, the animals receiving the mycotoxin contaminated diets without pomace gained less weight than the pigs receiving either...

Apparent N Balance in Organic and Conventional Low Input Cropping Systems
Provedor de dados: 21
Autores: Boldrini, Arianna; Benincasa, Paolo; Tosti, Giacomo; Tei, Francesco; Guiducci, Marcello.
The determination of nutrient surplus is one of the indicators of potential N losses from the agricultural system to the environment. An experiment was started in 1998 in Central Italy to evaluate the soil surface N balance of an organic and a conventional low input cropping system over a long term crop rotation. Results at the end of a 6-year crop rotation showed an estimated N surplus in organic system 1.3-2 times higher than in conventional system while N content in the top soil was not different in the two systems, so that organic system should have involved a higher N loss from that soil layer.

Apple and Pear Cultivars for Organic Production in a Cool Climate
Provedor de dados: 21
Autores: Røen, Dag; Hjeltnes, Stein Harald; Jaastad, Gunnhild.
Only early ripening cultivars of apples and pears may be grown successfully in the short and rather  cool growth season of the fruit producing areas of Norway. Due to a combination of high yield, good  fruit quality and scab resistance, the Swedish cultivar ‘Aroma’ is recommended as major cultivar for  organic apple production today. ’Philip’ is recommended as cultivar for organic pear production.  During 5 years 21 apple cultivars and 15 pear cultivars have been tested in organic orchards in  comparison with ‘Aroma’ and ‘Philip’. Several cultivars in the trial are promising for use in organic  production.

Apple scab control with grapefruit seed extract: no alternative to chemical fungicides
Provedor de dados: 21
Autores: Spitaler, Renate; Marschall, Klaus; Zidorn, Christian; Kelderer, Markus; Zelger, Roland; Stuppner, Hermann.
The growth inhibiting effect of four commercially available grapefruit seed extracts  on the causal organism of apple scab  Venturia inaequalis was tested. Germination of  the conidia of Venturia inaequalis was pronouncedly inhibited by all tested extracts.  The commercial products were analyzed by high pressure liquid chromatography and  thin layer chromatography. All samples contained at least one preserving agent.  These substances were identified as either benzethonium chloride, benzalkonium  chloride, methyl parabene or propyl parabene. Freshly prepared extracts from seeds  of grapefruits (Citrus paradisi) did not inhibit the germination of Venturia inaequalis. It  was therefore concluded that the antifungal effect of grapefruit seed extracts is...

Application of phenology models for Climate Services
Provedor de dados: 21
Autores: Felber, Raphael; Stöckli, Sibylle; Calanca, Pierluigi.
Global warming is expected to accelerate the development of plants and insects leading to earlier occurrence of phenological stages than under today’s climate. This can alter the exposure of plants to extreme climate events and further change the synchrony between host plants and pest insects. Assessing the implications of earlier development for the exposure to risks is necessary to inform adaptation.  In this contribution we present an analysis of potential impacts of climate change on (i) the risk of early frost in apple orchards and damages to apple fruits due to critically high temperatures, (ii) the time of apple picking, and (iii) the potential of damages caused by the codling moth (Cydia pomonella L.), for three different apple cultivars in...

Crop competition is a key component of an integrated approach to weed management.  Variation in competitive ability and competitive traits have been identified in many other crop species, however little work has been done on oats.    Trials were carried out over four years at one organic site with five husked and three naked oat varieties.  Mid-season Leaf Area Index (LAI) and tillering ability were identified as weed suppressive traits using path analysis.  Differences in weed tolerance were found among varieties.  Trade-offs may exist between competitive traits and yield potential which could be optimised by limiting competitive traits later in the season.  Selection of competitive traits with high heritability, whilst minimising yield penalties, could...

The AnM practices in peanut production included three steps. The three letters, A, n and M, showed the shapes of the section-cross of the ridge at the three steps of different growth stages of the peanut crop. First, the peanut seeds were sown a little deeper than usual, about 8 cm, in the ridge to induce the extra-elongation of the hypocotyl. When the seeds were sown, the cross-section of the ridge looked like the letter “A”. The second, the hypocotyls elongated more than usual were exposed to light and dry air by removing the soil away around the young seedlings just after the emergence. At this time, the cross-section of the ridge looked like the letter “n”. The third, at the middle growth stages, soils on the both sides of ridge were earthed up to...

Provedor de dados: 21
Autores: Fleck, M.
Since 1998 RODELIKA is officially registered as a newly bred carrot variety. It had been developed by positive mass-selection over a 13 year period, based on an old-established variety within a farm based biodynamic system. The goal was a fine root with good health and a focus on taste and ability of maturation. Thus a selection-scheme in organoleptic characteristics sweetness and aroma was created. Numerous investigations demonstrate the very high inner quality of RODELIKA. Property rights of this open-pollinated variety are held by the charitable association Kultursaat eV as a common heritage.

Although the European organic agriculture movement was founded by Rudolf Steiner and Hans Mueller in the years between 1924 and 1940, it was not until the 1980s that pest management researchers began to develop strategies to control pests in organic systems. Today, insect pest management in organic agriculture involves the adoption of scientificallybased and ecologically sound strategies as specified by international and national organic production standards. These include a ban on synthetic insecticides and, more recently, on genetically modified organisms (GMOs). The first phase of an insect pest management program for organic systems is the adoption of cultural practices including diverse crop rotation, enhancement of soil quality by incorporation of...

Apricot susceptibility to blossom brown rot (Monilinia spp.) and leaf rust (Tranzschelia spp.) under low-input production system
Provedor de dados: 21
Autores: Parveaud, Claude-Eric; Broquaire, Jean-Michel; Mercier, Vincent; Gomez, Christelle; Brun, Laurent; Clauzel, Guy; Guillermin, Armand; Audergon, Jean-Marc.
Production regularity in organic apricot orchards is highly constrained by blossom brown rot caused by Monilinia spp. infections on flowers. Leaf rust (Tranzschelia spp.) development can induce early defoliation, which is detrimental to tree vigour and yield. Copper-based treatments are partially efficient against both diseases but their negative environmental impact should be considered. The choice of cultivars according to disease susceptibility criterions is a key-step towards low-input production systems.  This poster presents the susceptibilities to blossom brown rot and leaf rust of 16 apricot cultivars observed during 5 years in two sites.

The working time requirement for different methods of biogas production forms the basis for a full cost calculation as well as for the planning of working capacities in biogas plant management. The aim of this study is to quantify the time requirement under different conditions. An ergonomic analysis was carried out for ten biogas model plants which differed in terms of gas utilisation and installed capacity as well as of substrate usage (energy feedstock and mass) and plant size. The results of the model calculations yielded a total working time requirement of between 679 and 2,140 MPh/year for the ten model plants from an electrical output of 75 kW to a gas supply of 700 m3 under normal conditions. The time required for feeding a plant increases in...

As existing figures on working-time requirements for outdoor runs in cattle husbandry are often out of date or insufficiently detailed for individual use and in particular as few reliable work-economics data are available for ecological forms of farming, figures on working-time requirements and influencing variables for dung removal and spreading of litter in outdoor runs in cattle and pig farming were recorded as a subproject within the framework of the KTBL-KU 2005 project. This report presents the results for dairy cattle husbandry. The calculations are based on an outdoor run area of 6 m2 per cow. Each outdoor run cleaning operation takes between 0.1 and 1.3 MPmin per cow, depending on the method used and the herd size. If the run is spread with...

Autores: Heitkämper, Katja; Mager, Kerstin; Schick, Matthias.
Obwohl die Haltung von Kleinwiederkäuern in den letzten Jahren immer mehr an Bedeutung gewonnen hat, gibt es bisher, insbesondere im Bereich der Milchgewinnung, nur wenige arbeitswirtschaftliche Kennzahlen für die Haltung von Schafen und Ziegen und deren Aufzucht. Insbesondere Schafmilch ist schon seit einiger Zeit als wichtige Alternative zu Kuhmilch bekannt. Es ist daher wichtig im Bereich der Kleinwiederkäuer Verfahrensdaten und arbeitswirtschaftliche Kennzahlen zur Verfügung stellen zu können.   Das Ziel der vorgesehenen Untersuchung liegt in der Erfassung, Aufbereitung, Auswertung und Bereitstellung von arbeitswirtschaftlichen Kennzahlen sowie der Beschreibung zeitgemässer Produktionsverfahren im Bereich der Kleinwiederkäuerhaltung.

Autores: Schrade, Sabine; Keck, Margret; Schick, Matthias.
There was a lack of up-to-date statistics on the working time requirements in suckler  cattle farming under Swiss production conditions. A combination of final and causal  methods for recording working time was used to determine working-time input and  working-time requirements, to survey influence variables and draw up working-time  models using a model calculation system. The total working time spent on suckler  cattle farming varied between 28 and 120 hours per cow per year, with an average of  66 hours per cow per year. Over half of this time was spent on routine work, 20 % on  management work, 19 % on other non-daily work and 3 % on direct marketing, animal  care and animal handling, respectively. The larger the herd size, the lower the time  spent on...

Der Arbeitszeitbedarf für Legehennen in Bodenhaltung unterscheidet sich kaum von dem in der Volierenhaltung: Gesamtarbeitszeitbedarf und Verteilung auf die einzelnen Arbeitsgänge sind annähernd gleich. Der größte Arbeitszeitbedarf liegt mit einem Anteil von 53 % bei der Produktgewinnung. Die Betriebsführung macht einen Anteil von 17% am Gesamtarbeitszeitbedarf aus. Bei beiden Arbeiten handelt es sich um tägliche, meist mit hohem manuellem Aufwand verbundene Tätigkeiten. Produktgewinnung, Betriebsführung, Fütterung und Auslaufbewirtschaftung summieren sich auf 92 % des Arbeitszeitbedarfs. Einfluss auf den Arbeitszeitbedarf haben vor allem die Bestandsgröße und der Anteil an manuellen Tätigkeiten.

ARBUSCULAR MYCORRHIZA OF WINTER WHEAT UNDER DIFFERENT DURATION OF ORGANIC FARMING
Provedor de dados: 21
Autores: Gollner, Manfred; Friedel, Jürgen; Freyer, Bernhard.
The effect of continuous organic farming (OF) on the arbuscular mycorrhizal fungi (AMF) of winter wheat (Triticum aestivum) was investigated in a greenhouse pot trial. Representative soil samples were taken from 5 farms in the “Weinviertel” region, northeast of Vienna, Austria. On each farm three sites with a different duration of OF were selected for soil sampling; wheat was used as test plant. The mycorrhizal colonization (MC), root length density (RD) and the mycorrhizal colonized root length density (MD) were evaluated for the wheat roots. The majority of the wheat plants indicated an increasing MC and MD with increasing duration of OF. Based on our results we assume that a conversion period from conventional to OF of approximately 15 years is needed...

Are consumers willing to pay a price premium for specific organic logos?
Provedor de dados: 21
Autores: Janssen, Meike; Hamm, Ulrich.
Since July 2010, prepacked organic food produced in the EU must be labelled with the new mandatory EU logo for organic food. However, there is a long tradition of voluntary organic certification logos in most European countries. In this paper we analyse the willingness-to pay (WTP) of European consumers for products with different voluntary organic certification logos to make recommendations for actors in the organic sector. Data was collected by means of choice experiments with 1,997 consumers of organic food in five EU countries, based on which a number of random parameter logit models were estimated. According to our results, there were great differences between the tested logos regarding the price premium that consumers were willing to pay compared to...

Provedor de dados: 21
Autores: Kristensen, Hanne L.; Kidmose, Ulla; Dresbøll, Dorte Bodin; Thorup-Kristensen, Kristian.
Differences in nutrient availability and methods of pest management may affect crop growth and product quality. The question is whether conventional and organic cropping systems, which differ clearly in strategies for nutrient and pest management, influence the harvest and sensory quality of the products? With the aim to elucidate this question, lettuce and onion were grown in a conventional and three organic cropping systems with increasing levels of nutrient re-cycling and use of intercrops for natural pest management in the period of 2007-2009. The conventional and first organic system relied fully on external inputs in the form of NPK or liquid manure for nutrient management, respectively. In the second organic system, low external inputs of liquid...

To evaluate the effects of homeopathics on clinical mastitis cows and herd udder health this investigation was conducted in a Brandenburg bio-dyn herd of about 300 cows in two phases using a randomized doubleblind control trial design. After the first part in July 2002 the results preliminarily were evaluated and then the whole concept due to unsatisfying results was adapted. In Phase 1 a number of 121 clinical mastitis cases with 137 affected quarters matched the including criteria, in Phase 2 the number was 126 cows with 148 quarters. These animals were allocated to a code number which classified the case to Verum (n=65 and n=60) or placebo group (n=56 and n=66).

Are Organic Consumers Healthier than Others?
Provedor de dados: 21
Autores: Krarup, Signe; Christensen, Tove; Denver, Sigrid.
Recent research results indicate that organic consumers have a healthier diet than other consumers. This suggests that there might be a positive relationship between organic consumption and a healthy lifestyle. One aim of an ongoing research project is to analyse whether consumers with a high organic consumption have a higher interest in nutrition and a healthy living than other consumers. In order to test whether such a causal relationship exists, purchase data from Danish households are combined with information on these households’ perception of organic food and their health concerns.

Are organically grown apples tastier and healthier? A comparative field study using conventional and alternative methods to measure fruit quality
Provedor de dados: 21
Autores: Weibel, F.P.; Bickel, R.; Leuthold, S.; Alfoeldi, T.
Since 1994 important supermarket chains in Switzerland successfully sell apples from verified organic production. However, in supermarkets customers often ask whether there are, apart from a more environmentally friendly production, objective arguments of inner fruit quality that justify the higher prices of organic apples.     In a field study with the ‘Golden Delicious’ cultivar, we harvested fruits of 5 pairs of organic/integrated fruit farms. The orchards within the pairs were less than 1 km from each other and were similar in micro climate, soil conditions and planting system. Maximum distance between the pairs was 180 km. To measure inner fruit quality we investigated at the beginning and at the end of cold storage (i) standard parameters (firmness,...

Are soil biological properties and microbial community structure altered by organic farm management?
Provedor de dados: 21
Autores: Stark, Dr C.H.
Environmental conditions and farm management practices have a considerable impact on soil biota, affecting nutrient cycling processes and ecosystem functioning. Understanding how management practices influence soil fertility and agricultural productivity is essential to improve the sustainability of agroecosystems. The effect of farming history on microbial soil properties was assessed by analysing soil samples from two organic and conventionally managed sites. Cmic and Nmic, enzyme activities, bacterial community composition (PCR-DGGE) and total numbers of fungi and bacteria (soil dilution plating) were determined. Results suggested that organic farming practices did not have a clear positive effect on soil microbial biomass and activity; distinct...

Are the motives of recent adopters in line with the conventionalisation hypothesis?
Provedor de dados: 21
Autores: Best, Henning.
To contribute to the discussion on the con-ventionalisation hypothesis, empirical data on mo-tives for the conversion to organic farming by recent adopters is analysed. The results indicate that the preferences and attitudes of the new organic farmers contradict the conventionalisation scenario: (1) Com-pared to conventional farmers, the new adopters have lower preferences for high yields, market prices and easy control of weed and pests, but higher prefer-ences for receiving subsidies and not using chemicals. (2) Environmental concern has an effect on the odds of an adoption of organic farming. Thus, new organic farmers significantly differ in their preferences and attitudes from conventional farmers – they hold a less productivist, relatively alternative...

„Are the organic consumer labels conveying the right message?“
Provedor de dados: 21
Autores: Richter, Toralf.
When supporting the organic sector, the specific needs of retailers and processors have to be taken into account, because these actors bear similar risks and higher costs by conversion to organic products like farmers.    Therefore projects should be supported which reduce the transaction cost of organic food processing, wholesaling and retailing and provide information (e.g. access to more valuable market information/data) and services.    Consumer communication has to be focussed on credibility, emotions and more on consequences of buying organic food as to transport just technical aspects of standards.

Aroma-active secondary oxidation products of butter
Provedor de dados: 21
Autores: Mallia, Silvia; Escher, Felix; Rehberger, Brita; Schlichtherle-Cerny, Hedwig.
Butter contains vitamins, minerals and unsaturated lipids, such as polyunsaturated fatty acids (PUFA) and conjugated linoleic acids (CLAs). However the oxidative stability and consequently the shelf-life of milk products are inversely correlated with their PUFA and CLA content.  The objective of this study is the evaluation of the oxidative stability and sensory quality of PUFA/CLA-enriched butter versus conventional butter, with both types of butter being produced at ALP. For this purpose, new chemical and sensory-based methods will be developed, as well holistic complementary methods.  This paper focuses on a preliminary study achieved using conventional butter, subjected to a long storage and to oxygen and light exposure, to develop a gas chromatography...

In two experiments it was investigated which factors to what extent determine the fatty acid composition milk when cows are grazing high alpine pastures. The influences of altitude per se, of alpine forage quality, of concentrate-free diet type and of the overall grazing effect were separated by the experimental design. The most important factor which significantly elevated the concentrations of CLA, α-linolenic acid (ALA) and n-3 PUFA in milk fat was found to be the alpine diet type, i.e. the feeding of roughage-only (as well hay as pasture of as well lowland as alpine origin) with omission of concentrates and maize. Additionally a clear positive effect of the forage quality of alpine pastures on ALA concentration in milk fat was found. The latter effect...

One of the aims of organic farming is the protection of biodiversity. In the EU FP7 project BioBio, we studied the effect of organic farming on species numbers at farm level on 169 randomly selected organic and non-organic farms with mostly low to medium intensity in ten European regions. Using a preferential sampling scheme based on habitat mapping, numbers of plants, earthworms, spiders and bees were assessed at farm level. A global analysis across the ten regions shows that organic farms have significantly higher numbers of plant and bee species than non-organic farms. The effect of organic farming on earthworm and spider species numbers are also positive but insignificant. The effects in absolute terms are small and much smaller than the variation...

Nowadays only eight percent of the cultivated field area is used for organic farming. The Ministry of Agriculture and Forestry has published the guidelines for the program of organic farming to diversify the supply and the consumption of organic food. The aim is to increase organically arable land to 20% by the year 2020.The demand of organic fertilizer products is strongly increasing. Interest in forestry by-products (ash, bark, zero fiber, etc.) for use in organic production has recently been exceptionally high. For example, development of pelleted fertilizers with zero fiber, ash and a nitrogen-containing fertilizer material is in progress.The ash fertilizer contains many valuable nutrients in fairly optimal ratios: these include phosphorus, potassium,...

Aspects of phosphorous fertilisation in organic farming
Provedor de dados: 21
Autores: Schnug, E; Haneklaus, S; Kratz, S; Fan, X.
Balanced fertilisation is essential for a considerate use of limited phosphorus (P) resources and for sustainability in organic farming. Plant available soil P levels will decrease and soil fertility will diminish when using P sources with limited P availability such as rock phosphates, bone and bone meals. An in situ digestion with a combination product of elemental S and rock phosphate enhanced significantly the solubility of non water-soluble P sources. In addition to the problem of insufficient solubility, mineral P sources can be contaminated with toxic heavy metals such as Cd  0.1–92.3 mg kg-1) and U (&lt;LLD - 481 mg kg-1) from their source. Farmyard manure and slurry may contain up to 953/727 and 376/132 mg kg-1 Zn and Cu, respectively.

In an organic fattening trial 62 pigs of the genotype (PixHa)x(DuxGLR) were divided into 2 groups which were fed during finishing period with a ration containing soy prod-ucts or farm grown grain legumes, respectively. The Methionin deficit of the second group did not affect negatively the fattening performance, whereas lean meat content decreased significantly. In spite of lower feed costs of the second group the profitabil-ity was lower.

Aspekte der Mast- und Schlachtleistung von Schweinen unterschiedlicher Genotypen in Freilandmast auf dem Fruchtfolgeglied Kleegras
Provedor de dados: 21
Autores: Weißmann, Friedrich.
Die ökologische Schweinehaltung ist zur Zeit nur wenig entwickelt. Die Gründe liegen vor allem in Unwägbarkeiten der Erzeugung sowohl in der Ferkelerzeugung als auch in der Schweinemast. Das ist insofern bedauerlich, als sich der Markt für ökologisch erzeugtes Schweinefleisch durch erfolgverheißende Prognosen auszeichnet (Branscheid und Weißmann, 2002). Ein wesentliches Problemfeld in der ökologischen Schweinemast besteht in der nicht ausreichend bearbeiteten Interaktion von betrieblicher Futtergrundlage und genetischer Herkunft der Masttiere im Hinblick auf die ökonomisch erfolgreiche Erzeugung marktfähiger Schlachtkörper- und Fleischqualitäten (= Schlachtleistung) mit der folgenden Begründung:  Derzeit stehen keine explizit für die ökologische...

Presprouting of seed tubers is a measure that is often recommended for organic potato growing. In on-farm field experiments the effect of presprouting was evaluated with respect to virus infection, yield and weed infestation. The effect of presprouting on yield was largely dependent on the year and on the late blight severity. Weeds were not affected significantly by presprouting. In most experiments virus incidence was higher in presprouted potatoes. Presprouting also had a suppressive effect on undesired regrowth after haulm destruction.

Assessing climate change impacts on fruit plant and pest phenology and their synchrony: the case of apple and codling moth
Provedor de dados: 21
Autores: Felber, Raphael; Stöckli, Sibylle; Calanca, Pierluigi.
Temperature is a main climatic driver of plant phenology and the dominant abiotic factor directly affecting insect pests. Global warming is therefore expected to accelerate the development of plants and insects alike. In the case of multivoltine pest species, it was shown that higher temperatures lead to the appearance of additional generations toward the end of the warm season (Stöckli et al., 2012), which also has implications for pest management. The same effect was shown for the timing of flowering termination of apple trees (Stöckli and Samietz, 2015), the time when a pest can attack a fruit. In practice, however, much would depend on whether plant and pest phenology remain synchronized or not.    Focusing on Switzerland, in this contribution we...

Autores: Hamm, Ulrich; Wild, Sandra.
This paper presents and comments the results of sales experiments on newly developed organic meat products. The main goal of a research study was to examine the issue of consumer acceptance of organic sausage products with no curing agents. The sales experiment lasted over 12 weeks and was run in six supermarkets offering several variants of organic sausages of which three were produced without curing agents and therefore looked different to the variants produced with nitrite. The results allow an analysis of the consumer acceptance for organic meat products produced with and without curing agents as well as a description of the influence of the introduction of organic sausage variants without nitrite on the share of total sales of organic and conventional...

Assessing nutrient and sediment transport for Water Framework Directive  purposes using the SWAT model - a case study in SW Finland
Provedor de dados: 21
Autores: Bärlund, Ilona; Kirkkala, Teija; Kämäri, Juha.
The ecological status of lake Pyhäjärvi, located in south-western Finland, may be classified as moderate due to its elevated nutrient concentrations and algal biomass production. Thus, the Yläneenjoki river basin, accounting for &gt;50% of the total phosphorus loading to the lake, was chosen as the Finnish test catchment in the Benchmark models for the Water Framework Directive project. One aim of the project was to test the suitability of models like the catchment scale model SWAT for the assessment of nutrient and sediment transport and management options needed to meet the surface water quality requirements.

Assessing organic food quality: Is it better for you?
Provedor de dados: 21
Autores: Heaton, Shane.
This report was presented at the UK Organic Research 2002 Conference. Any attempt to answer the question ‘is organic food better for you?’ requires an assessment of the safety, nutritional content and biological value aspects of food quality. Previous reviews have been unable to reach definitive conclusions after failing to ensure only valid comparisons are considered. When methodologically flawed studies are screened out and a complete assessment of nutritional quality is made, collectively, the available evidence supports the hypothesis that organically produced food is superior in terms of safety, nutritional content and nutritional value to that produced non-organically. More research is needed provide to more data further investigating the trends seen...

Autores: Gubanova, Tatiana; Escalante, Cesar; Lohr, Luanne; Park, Timothy.
This project develops price forecasting models to guide organic commodity marketing decisions.  Forecasting models for organic commodity prices at the farm level are specified and tested using a comprehensive national farm price series data set collected for organic commodities in the United States.  A framework for testing the predictive ability of competing models using conditional predictive ability is developed.  Forecast performance is evaluated using the root mean squared error (RMSE) and mean absolute error (MAE) for point forecast comparison along with tests for market timing ability of the forecasting model.

Autores: Shepherd, Mark; Hatley, Damian; Gosling, Paul.
This report was presented at the UK Organic Research 2002 Conference. Soil structure was assessed in over 90 fields (organic and conventionally farmed) covering mixed, stockless and pasture farming systems. A combination of spade and an objective scoring system based on the degree of aggregation and porosity was able to detect differences between fields. On average, in the fields sampled, topsoil structure was slightly better on the organic farms though, even on the conventional fields, structure was unlikely to limit crop growth.

Assessing the public goods provided by organic agriculture: lessons learned from practice
Provedor de dados: 21
Autores: Smith, Laurence; Padel, Susanne; Pearce, Bruce; Lampkin, Nic; Gerrard, Catherine L; Woodward, Lawrence; Fowler, Sue; Measures, Mark.
The role of farms as providers of public goods has long been recognised, and measuring performance in this area is of increasing interest to policy makers, in light of the approaching Common Agricultural Policy reform. The Organic Research Centre has been working on this topic in recent years, through the development of sustainability assessment tools. The latest outcome from this process is a ‘Public Goods’ assessment tool, developed through a Natural England funded project which aimed to evaluate the benefits accruing from organic management and entering into an Organic Entry Level Stewardship (OELS) agreement. This paper describes the development of the Public Goods (PG) tool, and what has been learned in the process.

Assessing the risk from mycotoxins for the organic food chain: results from Organic HACCP-project and other research
Provedor de dados: 21
Autores: Wyss, Gabriela.
Introduction:  Mycotoxins are toxic compounds produced by the secondary metabolism of toxic moulds in the Aspergillus, Penicillium and Fusarium genera occurring in food commodities and foodstuffs. The range and potency of mycotoxins make this group of naturally occurring toxins an ongoing animal health hazard and a constant risk for contamination of the food supply.    Mycotoxicoses are diseases caused by exposure to foods or feeds contaminated with mycotoxins. Mycotoxins exhibit a variety of biological effects in animals, such as liver and kidney toxicity, central nervous system effects or estrogenic effects. There are differences between animals with regard to the susceptibility towards different mycotoxins. Poultry secrete mycotoxins relatively fast...

Assessing the role of the research in the transition to organic farming by using the Actor Network Theory: lessons from two case studies in France and Bulgaria
Provedor de dados: 21
Autores: Quiédeville, Sylvain; Slavova, Petya; Touzard, Jean-Marc; Barjolle, Dominique.
This paper explores the potential of Actor Network Theory (ANT) in understanding how the process of interaction and translation between human and non-human actors contribute to the development, adoption and diffusion of science-based innovations linked to the transition to organic farming. The study relies on two case studies, the French Camargue case covering a range of technical and social innovations, and the case from Bulgaria focusing on the development of a technical and product innovation, i.e. a veterinary product for organic beekeeping. The paper shows the limitations of classical approaches in studying innovations since they underestimate the role of heterogeneous actors, their status, and how they interact with each other. We argue that focusing...

During this presentation the CoreOrganic2 project ProPIG was introduced and methods to assess animal welfare and environmental impact were presented. Furthermore some examples were given and models to relate animal welfare and environmental impact were discussed. It was concluded that selected aspects of animal welfare and environmental impact can be assessed on farm, however, it remains to discuss how to relate them to each other- a concrete hypothesis and specific, measureable outcomes are required. The high influence of management makes the variation within systems larger than across systems, allowing to identify solutions.

Autores: Hovmøller, M.S.; Pinnschmidt, H.; Willas, J.; Østergård, H.
Disease assessment is the basis for describing disease resistance characteristics of commercial varieties in national variety lists for all crops where disease is considered a problem. It is well known that ‘disease’ in a specific situation depends on a whole range of interacting hosts, pathogens and environmental conditions. However, the biological complexity conflicts with the wish to express disease resistance characteristics of a variety as a single score per disease. This problem will be illustrated by basic dynamics of growth and senescence of both host and pathogen over time. Disease expressed in terms of absolute diseased leaf area, disease relative to total leaf area or green leaf area will be discussed in general. Two particular problems in...

A long-term field study was used to compare soil nitrogen and phosphorous status, and soil aggregate stability in organic and conventional cropping systems.  Two rotations were tested: a grain only and a grain-alfalfa hay rotation.  The organic systems had a lower nitrate leaching potential than the same rotations under conventional management.  After 13 years, one organic system (the grain-alfalfa; no manure return) is suffering serious soil P depletion. However, the grain only and the grain-alfalfa with manure return to land systems had soil P levels similar to the prairie grass control treatment and showed no signs of P deficiency.

One of the keystones of the organic orchard is the cultivar choice as one element of pest and disease control. However, few exhaustive data sets concerning the cultivar susceptibility to pests and diseases are available for growers. In order to identify cultivars adapted to organic production methods, the susceptibility to scab, aphids and powdery mildew and the agronomic properties of 36 cultivars were assessed in four French sites under different pedo-climatic conditions. Different levels of susceptibility to scab were observed for 23 scab Vf-resistant and 13 other cultivars.

Assessment of tillage systems in organic farming: influence of soil structure on microbial biomass. First results
Provedor de dados: 21
Autores: Vian, Jean François; Peigné, Joséphine; Chaussod, Rémi; Roger-Estrade, Jean.
Soil tillage modifies environmental conditions of soil microorganisms and their ability to release nitrogen. We compare the influence of reduced tillage (RT) and mouldboard ploughing (MP) on the soil microbial functioning in organic farming. In order to connect soil structure generated by these tillage systems on the soil microbial biomass we adopt a particular sampling scheme based on the morphological characterisation of the soil structure by the description of the soil profile. This method reveals the influence of soil structure on soil microbial biomass and allows a more precise assessment of the impact of tillage managements on the soil microbial functioning.

Low external inputs agriculture does not automatically confer on traditional farmers the status of organic farming. This study assessed traditional agricultural practices for compliance with organic practices in Nigeria. Information was obtained from 177 crop farmers in 6 states of 3 agricultural zones in Nigeria, while frequency counts, percentages, mean, and PPMC were used to analyse the data. The result shows that majority were male (69.0%), the mean in years for; age (47.7), formal education (10.5), farming experience (26.5), and farm size (5.8) in hectares with average monthly income of N30,485.76 and most (52.0%) had access to extension service fortnightly.

Assessment of two modern milk farms (low input versus high external input) in Switzerland focused on sustainability and resilience criteria
Provedor de dados: 21
Autores: Schmid, Otto; Näf, Philippe.
In many countries there is a trend in milk production to either maximize the milk yield with high inputs and modern milking technology or to choose a low external input strategy with emphasis on grazing. What about the sustainability and resilience of such types of farms? In this paper a comparison of two modern milk farms in the same region and village in Switzerland with similar climatic conditions and new free-range stables has been made. Both farms are run collectively. Farm A is a non-organic milk farm (integrated production) with milk robot machinery and high input of feed concentrates for milk production without using pasture but with a concrete outdoor run. Farm B is an organic milk farm with consequent low input milk production with full pasture...

Associating wheat crop and undersown forage legumes in organic agriculture: Incidence of forage legumes species
Provedor de dados: 21
Autores: Celette, Florian; Goulevant, Gael; Amosse, Camille; David, Christophe.
One of the key issues of organic arable systems is to increase use of N2 fixation from legume plants while enhancing autonomy by the limitation of off-farm inputs. Wheat yield in organic agriculture is generally low and variable. Grain yield and protein content are strongly affected by N deficiency and weed competition (Casagrande et al., 2009). Previous research had clearly demonstrated the benefits of forage legumes to improve N balance and preserve weed infestation (den Hollander et al., 2007). Several authors highlighted the interest of crop mixtures combining cereal and legumes to provide higher overall productivity, enhance ecological services and improve economical profitability (Malezieux et al., 2008). Nevertheless, previous research also...

Association mapping for barley traits related to organic farming
Provedor de dados: 21
Autores: Backes, G.; Kristensen, K.; Østergård, H.
In context of a larger project dealing with the traits of barley that are related to organic farming (BAR-OF), we performed an association mapping in order to dertermine the genetic loci linked with the respective traits. In two subsequent years (2002 and 2003), we used field results from 96 barley lines and varieties, partially overlapping between the years. The lines/varieties were grown on three Dansih locations (Flakkebjerg, Foulum and Jyndevad). For Foulum and Flakkebjerg, we observed both fields grown under organic and conventional regime; for Jyndevad only fields cultivated under organic conditions were ecploited. Neither in the organic nor in the conventional fields; diseases were controlled chemically. In the resulting five environments per year,...

Association Mapping for Common Bunt Resistance in Wheat
Provedor de dados: 21
Autores: Steffan, Philipp; Borgen, Anders; Backes, Gunter; Rasmussen, Søren K.
Common bunt, caused by Tilletia caries and T. foetida, is a fungal disease of wheat world wide. Infection, occurring via seed borne teliospores, is generally controlled by the application of seed treatments prior to sowing. Farming systems like organic agriculture with a very limited range of organic seed treatments available rely heavily on common bunt resistance genes within wheat. In the framework of the BIOBREED project an association study in winter wheat was conducted, aiming at the identification of genetic loci linked to resistance towards common bunt in wheat.  152 European wheat cultivars were phenotyped for their resistance reaction for the two consecutive years 2011/12 at Agrologica research station at Mariager. Infection was scored as percent...

Associations between pig leg health and lean meat growth in commercial organic herds
Provedor de dados: 21
Autores: Wallenbeck, A.; Eliasson, C.; Alarik, M.
Sustainable development of organic pig production needs to include both animal welfare and productivity aspects. Knowledge about associations between animal welfare and productivity could be a key for constructive, long-term development of organic as well as conventional pig production systems. Poor leg health is considered a central animal welfare issue in organic pig production in Sweden. The preliminary results presented in this paper indicate that pigs in organic herds with more severe leg problems have poorer lean meat growth. However, the majority of the lame pigs had milder forms of leg problems, which were not found to be associated with lean meat growth.

Essential oils can have an impact on pollen beetle (Meligethes spp.). Lavender oil (Lavendula angustifolia) showed the highest repellency value in a previous laboratory study (Mauchline et al., 2005). However, lavender oil is one of the most expensive essential oils – a fact that could seriously hamper on-farm implementation of this strategy. To find a cheaper essential oil with comparable efficacy to lavender oil, we compared the essential oils of Mentha arvensis, Eucalyptus globulus, Melaleuca alternifolia, Citrus sinensis, Citrus paradisi, Citrus limon, Juniperus mexicana, Abies sibirica, Illicium verum, Gaultheria procumbens, Cymbopogon flexuosus, Syzygium aromaticum, and Litsea cubeba using a Y-tube-olfactometer.

Attitudes and decision making amongst Scottish organic farmers
Provedor de dados: 21
Autores: Bayliss, Caroline; Clay, Tony.
The number of organic farmers in Scotland increased dramatically in the period between 1997 and 2000, from 120 in 1997 to approximately 600 at the end of 2000; a five fold increase. Currently the outlook for organic farming in Scotland appears positive, despite recent publicity about farmers leaving the sector. Market prospects for all organic commodities are buoyant and there are increased Scottish Executive Organic Aid Scheme (OAS) maintenance payments in the offing. But what do Scotland’s organic producers really think about the system, which has them, tied in for at least five years?  In June 2004, a representative group of Scottish organic farmers in the South of Scotland was surveyed to determine how many intended to continue farming organically once...

Autores: Vidal, Stefan; Mävers, Frauke; Brandl, Michael; Przyklenk, Michael; Schumann, Mario; Patel, Anant.
Soil dwelling pest species are difficult to control because of their cryptic life style and their unpredictable distribution belowground. The efficacy of biological control agents is limited, mainly because of low rhizosphere competence. Here we propose to use a strategy where pest are attracted to killing agents instead of bringing killing agents to the pest. We developed capsules emitting carbon-dioxide which are combined with an specific isolate of an entomopathogenic fungus or Neem. The principle of an attract &amp; kill strategy takes advantage of the behaviour of soil dwelling larvae which use CO2 for locating their host plants. Components used for the production of the capsules are just contain biologically derived substances and therefore do not...

Apple fruit moth, Argyresthia conjugella Zell. (Lepidoptera: Argyresthiidae), is the most important  pest of apples in Scandinavia. In years when its primary host, rowan (Sorbus aucuparia L.), has little  or no berries for egglaying, female A. conjugella fly into apple orchards to lay their eggs. In some  years the entire apple crop can be destroyed. Volatiles from apples and rowan have been collected  and identified. In GC-EAD tests females have responded to several compounds found in both  rowan and apple. Some of these compounds were used in field trapping tests during 2002, and a  mixture of two compounds trapped significantly more females and males compared to control traps.  However, field trapping results from 2003 indicate that the two-compound...

As livestock farming in general, organic livestock farming contributes to emissions of ammonia, odour and particulate matter. Especially for yards and free ventilated housings there is only little knowledge on the magnitude of emissions. This often complicates authorization processes for constructing new or altering existing housings.  Main issues of the workshop are: requirements in authorization processes, measures to reduce emissions and emission measurement standards. Ongoing projects are presented and their relevance as well as knowledge gaps for organic farming are discussed.

In organic laying hens husbandry it is desirable that the animals cover a proportion of their daily fodder intake by foraging in the outside run, e.g. by grazing. So far, however, few studies have investigated the factors which influence herbage intake of laying hens. In the present experiment we analysed the foraging behaviour of laying hens in the outside run at different conditions of sward botanical composition and of percentage ground cover of vegetation. The animals were taken to pasture on monocultures and a mixed plot of fourteen grassland plant species for three levels of period of stay in a rotational grazing system. By means of point sampling, we recorded scratching, plant pecking and ground pecking. Our results indicate that the factor plant...

The aim of the present study was to evaluate the transfer of learning of the professional training course “Ausbildung zum Weidepraktiker”. An online questionnaire (17 questions) was developed and sent out to alumni of the course. A return rate of 48 % was achieved. The results show that a number of the studied key aspects of the course were already implemented by the participants before visiting the training. Actions implemented because of the professional training were these which required expert knowledge. More than 70 % of the participant believed that the training motivated them to optimise their pasture management and 67 % rated the training´s benefit for agricultural practice as excellent. The majority of the alumni believed that there should be a...

Autores: Géneau, Céline; Schlatter, Christian; Daniel, Claudia.
Pollen beetles (Meligethes sp.) are important pests in oilseed rape (Brassica napus).  In our study we wanted to determine which landscape structures have an influence on pollen beetle population in early spring. The dynamics of pollen beetle population and  the damages on rape were studied on field scale level with 100 sampling points per field and on landscape scale level with 18 organic oilseed rape fields which differed by  the complexity of the surrounding landscapes. The number of pollen beetle was strongly correlated with the distance to a forest. At the beginning of the flight period more pollen beetles were found close to the forest, later they migrated to the rest of the field. In addition, agricultural practices appeared to be determinant for...

Shading with nets of 2 m and 3 m width respectively, which reduce the photosynthetic  active radiation by 74%, lead to successful fruit thinning of apple trees. In field trials,  three days of shading reduced fruits per 100 flower clusters to a satisfactory extent for  Golden Delicious (if shading occurred after 19, 26 and 33 days after full bloom  (DAFB)) and Topaz (if shading occurred after 19 and 26 DAFB). For Elstar, seven  days shading at 25 DAFB resulted in a good thinning effect. However, practicability of  the method in commercial orchards has to be improved.

Autores: Clever, Michael.
Thinning trials with lime sulphur in comparison to other products were carried out for 4 years in an ‘Elstar orchard’ at the OVB Jork in Northern Germany. Beside the yield, the influence on fruit size, colour, russet-ting and return bloom of treated trees were observed. Mechanic thinning was too strong and had other negative effects. Thinning with potato meal and coconut soap had no effect. Organic oil (Telmion) reduced the yield between 0 and 20%. Lime sulphur reduced the yield 0 – 40% in comparison of the concentration and the number of applications. There were great fluctuations from year to year. In conclusion lime sulphur gives the best results, but the variation from year to year is not acceptable for a practical advising in the northern area of...

Ausfallkosten durch Eutererkrankungen und Lahmheiten auf  ökologisch wirtschaftenden Milchviehbetrieben in Deutschland
Provedor de dados: 21
Autores: Hoischen-Taubner, Susanne; Krieger, Margret; Sundrum, Albert.
Production diseases have severe economic impacts in dairy farms. Financial losses due to culling, decreased productivity, discarded milk as well as costs for treatment  and labour efforts are failure costs related to the occurrence of production diseases. To support decision making regarding herd health measures, failure costs caused by clinical and subclinical mastitis as well as mild and severe lameness were assessed on 60 organic dairy farms in Germany. Failure costs varied substantially between  farms. Decision-making in terms of animal health requires a farm specific calculation of failure costs to enable the identification of those measures that provide the best  cost-benefit relationship.

Approximately 13 % of the total greenhouse gas emissions in Germany are caused by agricultural practices. From an environmental and economic point of view, gaseous N losses as well as nitrate leaching to groundwater play, a significant role. The aim of the present study is to analyze abiotic environmental effects of organic and conventional all-arable farming at a highly productive site in Northern Germany. Two different organic crop rotations with 25% vs. 40% legumes and no application of external N-fertilizers were compared over a two-year period to a typical site specific conventional rotation at an average mineral fertilser input of 195 kg N ha-1 a-1. For gas flux measurement, the closed-chamber method was applied. Nitrate leaching was measured by...

Autores: Walther, Bernd; Pelz, Dr. Hans-Joachim.
Cyclic vole species, particularly the Water vole (Arvicola terrestris), cause substantial agricultural damage throughout their wide geographical range. In organic pomiculture synthetic pesticides are not allowed. Trapping and fumigation remain the only applicable measures for managing voles but require a lot of time and personal skills. The success of using these methods is reduced by the fast recolonisation of the empty areas. To stop the permanent overground immigration of voles a mechanical barrier system was developed and tested in enclosures and at two study sites in Baden-Wuerttemberg and Rhineland-Palatinate between October 2002 and October 2003. The barrier, consisting of a low fence of whire mesh or polyolefin foil, reached 20 cm below and 30 cm...

Autores: Darnhofer, Ika; Eder, Michael; Schmid, Johann; Schneeberger, Walter.
The end of the first five-year contract period of the Austrian Agri-environmental Program (ÖPUL) caused a number of farmers to opt out of the measure organic farming at the end of 1999 and in the following years. A survey was made in 2003 to explore the reasons for reverting to conventional farming. The three most important reasons were the high cost of organic grain for feed, the lack of price premia for organic products (mostly beef and milk) and the frequency of changes in organic standards. Most respondents operate grassland-based dairy farms in Alpine regions. The average size of the farms opting out was 12,0 ha.

Autores: Scheller, Edwin; Cuendet, Catherine; Müller, Jens; Werren, Dagmar.
Fazit: Es gibt einen Austausch bzw. Kreislauf von Aminosäuren und Proteinen zwischen dem Boden, Pflanzen und der Atmosphäre. Blütenpollen dominieren im Frühling die Proteingehalte in den erdnahnen Luftschichten, während in der übrigen Jahreszeit Böden und Pflanzen die Hauptquellen zu sein scheinen. Aminosäuren und Proteine der erdnahen Luftschichten werden durch Tau und Regen auf die Pflanzen und die Böden wieder niedergeschlagen. In der Luft werden sie von Mensch und Tiereingeatmet oder über die Schleimhäute aufgenommen. In einem Ökosystem besteht ein Stoffaustausch über die erdnahen Luftschichten zwischen den einzelnen Kompartimenten, über deren Bedeutung für Mensch, Tier und Pflanzenwachstum wir noch sehr wenig wissen.

Autores: Hein, Waltraud; Waschl, Hermann.
In this project, located at Winklhof, a comparison between organic and conventional farming is done. The field trial combines a crop rotation with two levels of fertilisation intensities (one is 1.0 LU ha- and the other is 1.8 LU ha-1). The fertilisation-systems are stable-manure and liquid manure, the treatments were done organically. The aim of this project is to find out which production system is better for the environment in spite of crop yield, product quality and leaching losses. The last parameter was measured in lysimeters. A high amount of yearly precipitation could account the high amount of seepage water. Consequently the leaching losses of both production systems could be compared.

Farms in the EU receive considerable support via the Common Agricultural Policy. Support to organic and conventional farms are analysed covering a wide range of different support measures of the Common Agricultural Policy. Results show that the design of the Common Market Organisations can pose a disadvantage to organic farming systems, even though developments of the last two CAP Reforms (year 1992 and 2000) and the latest reform (2003) have reduced the discrimination of extensive farming systems and provide an opportunity to design suited measures to meet part of the needs of organic farms.

Autores: Böhm, Herwart.
Futterleguminosen weisen in Blättern hohe Eiweiß- und Aminosäuren¬gehalte auf und könnten somit bei der Erreichung der 100%-Öko-Füttreung einen wesentlichen Beitrag leisten. Neben der Futterleguminosenart und der Sorte kann auch die Nutzungsfrequenz einen Einfluss haben. Hierzu werden am Thünen-Institut für ökologischen Landbau am Standort Trenthorst Feldversuche durchgeführt. Erste Ergebnisse zeigen, dass der Gesamtertrag bei höherer Nutzungsfrequenz zwar abnimmt, dafür jedoch der Blattanteil signifikant erhöht wird. Die Zielgrößen Blattertrag als auch Rohproteinertrag der Blattmasse liegen in beiden Nutzungssystemen auf gleichem Niveau.

Die nachhaltige Erhaltung und Steigerung der Bodenfruchtbarkeit ist für ökologisch wirtschaftende Betriebe von höchster Bedeutung. Im Ökologischen Landbau hängt das Niveau der Bodenfruchtbarkeit – abgesehen von den kaum zu beeinflussenden standörtlichen Gegebenheiten – sehr von der Leistungsfähigkeit der Leguminosen ab. Vor allem durch ihre Fähigkeit, Luftstickstoff zu binden und diesen für ihr eigenes Wachstum sowie für die Folgekulturen verfügbar zu machen, bilden Leguminosen die Grundlage der Bodenfruchtbarkeit im Ökologischen Landbau. In der Konsequenz bedeutet dies, dass Beeinträchtigungen der Leistungsfähigkeit der Leguminosen nicht nur deren eigenen Ertrag sondern auch die Leistungsfähigkeit der gesamten Fruchtfolge am Standort begrenzen.

At the biodynamic farm Juchowo, 7 pairs of dairy cows from 2 breeds (Holstein (HF) and Brown Swiss (BS)) were milk sampled in summer and in winter. Cows are grazed in summer and fed hay in winter. Differences in the milk fatty acid profile were evaluated for effects of month (fodder), breed and individual cows. The most important way to improve the FA quality is through grazing of fresh grass. Therefor milk from grass based systems should be preferred. Overall breed effects were small, but there are still possibilities present to select individual cows to get an improved FA quality profile in terms of CLA, n-3 FA and delta-9-desaturase activity.

The definition of reference flow can introduce a bias between organic and conventional farming systems. We strongly encourage to include definition of reference flow calculation, choice of algorithm for energy calculation as well as choice of energy content of milk in the  communication of any results.

Auswirkungen der Beregnung von Kartoffeln in Abhängigkeit der Stallmistdüngung auf den Ertrag, die Qualität sowie die Verarbeitungseignung zu Pommes frites und Chips
Provedor de dados: 21
Autores: Krause, Tanja; Böhm, Herwart; Loges, Ralf; Taube, Friedrich; Haase, Norbert U.
Ökologisch erzeugte Kartoffeln, die zur Verarbeitung zu Pommes frites oder Chips genutzt werden sollen, müssen besondere Qualitätseigenschaften aufweisen. So wird beispielsweise ein mittlerer bis hoher Stärkegehalt bei gleichzeitig niedrigen Gehalten an reduzierenden Zuckern gefordert. Um den von der verarbeitenden Industrie geforderten Qualitätsansprüchen gerecht zu werden, ist neben einer ausgewogenen Düngung gerade auf leichten Böden auch eine ausreichende Wasserversorgung entscheidend, die oft nur über Beregnung sichergestellt werden kann. Unter den Fragestellungen, ob organischer Dünger (Stallmist) durch die Beregnung besser von den Verarbeitungskartoffeln ausgenutzt werden kann und inwiefern Ertragsstruktur und die Qualitätsparameter von...

Auswirkungen der Einbindung einer Biogasanlage in ein ökologisches Betriebssystem
Provedor de dados: 21
Autores: Helbig, Susann; Grass, Rüdiger; Hülsbergen, Kurt-Jürgen.
Biogas plants gain increasing circulation in organic agriculture. Among systems engi-neering effects on matter cycles, soil, plants and environment particularly depend on the integration of the biogas plant into the farming system. Ecological effects should already be taken into consideration in the planning stage. Therefore appropriate tools are required.  In this contribution ecological effects of changing an organic cash crop farming system into a biogas system are shown by using an established modelling approach. Starting from an existing cash crop farm a biogas-scenario was developed which includes e. g. structural adaptations of the cultivation system and crop rotation, the use of internal products and manuring. The biogas plant was conceived as a...

Auswirkungen der Einführung einer „ökoeffizienten Weidemilchproduktion“ auf die Feldvogelbestände des ökologisch bewirtschafteten Lindhofs
Provedor de dados: 21
Autores: Neumann, Helge.
Die Ergebnisse eines Langzeit-Monitorings der Feldvogelbestände auf dem ökologisch bewirtschaftetem Lindhof in Norddeutschland zeigen, dass die Vogelbestände im Anschluss an die Einführung einer Milchviehhaltung mit kleegrasbasierter Portionsweide zurückgegangen sind. Ausgleichende Effekte lassen sich womöglich dadurch erzielen, dass große Schläge geteilt und parallel für die Kleegrasweide und den Anbau von Marktfrüchten genutzt werden.

Autores: Offermann, Dr. Frank; Sanders, Dr. Jürn; Nieberg, Dr. Hiltrud.
The 2003 CAP reform has a strong influence on the financial performance of organic  and conventional farming by decoupling direct payments and reducing price support.  This paper aims to identify and assess the impact of the CAP reform on the relative  profitability and production structure of organic farms in Germany. The statistical  analysis of FADN data from the years 2003/04 and 2006/07 suggests that differences  in payments from the first pillar decreased as a result of the reform, affecting positively  the relative profitability of organic farms. A survey among German organic farmers  revealed however that only a minority attributes changes in profits to the CAP reform  and decoupling, respectively. This suggests that organic farmers still require...

Auswirkungen der Fermentation biogener Rückstände in Biogasanlagen auf Flächenproduktivität und Umweltverträglichkeit im ökologischen Landbau bei viehloser Wirtschaftsweise
Provedor de dados: 21
Autores: Stinner, Walter; Möller, Kurt; Leithold, Günter.
Problemstellung/Ziele:Analog zur Entwicklung im konventionellen Landbau ist auch  im Ökologischen Landbau eine zunehmende Tendenz zu viehloser Wirtschaftsweise  festzustellen. Viehlose Betriebe können auf die Vorteile des Kleegrasanbaues (N-Versorgung,   Unkrautbekämpfung) kaum verzichten. Üblicherweise wird der Aufwuchs  gemulcht und auf der Fläche belassen, ebenso die übrigen Rest- und Koppelprodukte  (Stroh von Getreide und Körnerleguminosen, Zwischenfruchtaufwüchse, u.ä.). Damit  können erhebliche N-Verluste verbunden sein, zum Einen als Ammoniakfreisetzungen  beim Abbau des Kleegrasmulches (u.a. ANDREN, 1987), zum Anderen durch Minderleistungen  der Stickstofffixierung gemulchter Bestände, die mineralisierten Stickstoff  aufnehmen und dabei die eigene...

This paper analyses the impacts of the 2003 CAP reform on organic farms, combining an extensive survey of organic farmers in several EU member states with a farm modelling approach based on the European Farm Accountancy Data network. The results highlight that income effects will depend strongly on individual national imple-mentation of the 2003 CAP reform, and will often differ by farm type. In general, the impact will be more beneficial to organic farms in countries that have opted for full, rather than partial, decoupling, and in countries which have implemented the Single Farm Payment on the basis of regional payment rates rather than on the basis of historical, individual farm references.

Autores: Barth, Dr. Kerstin; Schneider, Regula; Roth, Béatrice; Hillmann, Dr. Edna.
The introduction of mother-bonded calf rearing into organic dairy farming faces some  problems. Regarding the cow, the disturbed milk ejection seems to be the most important  one. We compared two groups of cows, which had permanent (Kp, n=11) or temporarily  (Kt,n=13) contact to their calves until the 90th day p.p. with cows separated  from their offspring within 24 h after calving (Ko, n=24). Since suckling following the  machine milking strongly influences milk ejection, the Kt-cows were allowed to meet  their calves 15 minutes before the usual milking times (milking interval 10:14 hours) in  a separated area. Milk flow curves were recorded at the 6th day after calving and  afterwards every fortnight at least until the 90th day of lactation. At the same...

The current experiment was conducted to specify the effect of different diets on the quality of pork with emphasis on the intramuscular fat content in the M. longissimus. The results confirm the preliminary conclusions of a former experiment that it is possible to affect the amount of intramuscular fat content by a feeding strategy adapted to the organic framework conditions without increasing the overall fat content of the carcass.

Ziel der Arbeit ist es, die Auswirkungen von Sortenmischungen bei unterschiedlicher Nährstoffversorgung auf Backqualität, Ertrag und Krankheitsbefall im Ökologischen Landbau zu überprüfen.   Die Ergebnisse der Versuche legen nahe, daß Interaktionen zwischen Standortbedingungen, Jahr und Sorte sehr groß sind aber insgesamt die Mischungen die Backqualität nicht beeinträchtigen. Die Datenbasis ist aber für die Formulierung von Empfehlungen nicht  breit genug. Um den Einfluß von Standortfaktoren und Mischungen auf Krankheitsbefall, v.a. Fusariosen, Backqualität und Mykotoxin-belastung zu quantifizieren wurden für 2002/2003 Praxisversuche an 12 Standorten mit Reinbeständen und Mischungen angelegt.

In this study the lying down behaviour of sows was analyzed to find out whether there are differences in the amount of crushed piglets per litter when sows show varying  lying down behaviour. The lying down behaviour of the sows, litter size, number of stillborn piglets and number of dead piglets and cause of death during the weaning  period were recorded. The data was collected on seven organic farms in Austria and on two agricultural research stations. It was shown that animals that lie down slowly  crush fewer piglets than sows that let their hind quarter drop quickly to the floor.

Despite the increase in organic cropland, knowledge on the impact of organic farming on soil-derived nitrous oxide (N2O) and methane (CH4) emissions is rather limited. To improve the knowledge base, N2O and CH4 fluxes were investigated in a 571 day lasting cropping sequence in the “DOK” field trial. Two organic and two non-organic farming systems and an unfertilized control were chosen. For the whole monitoring, the two organic systems combined emitted 40% less N2O than the two non-organic ones cumulated on area-scale. Yield-scaled cumulated N2O emissions were nearly 10% lower for the organic systems combined, despite the yield gap of 27%. We found that besides N input, management induced soil quality properties drive differences in N2O emissions between...

Autores: Lobsiger, Martin; Mosimann, Eric; Jeangros, Bernard; Lüscher, Andreas.
The consequences of a late closing date in autumn on pasture performance in spring are mostly unknown under Mid-European climatic conditions. An experiment on two sites in the Swiss lowlands showed that a delay of the closing date from early October to late November reduced spring yield by 50% (238-821 kg DM/ha) in early April and 18% (556-986 kg DM/ha) in Mai. This reduction of spring yield was particularly high (up to 75%) if the residual herbage mass before winter was below 300-500 kg DM/ha. On the other hand residual herbage mass above this threshold did not increase spring yield considerably. Thus, the utilisation of pasture in late autumn is recommended, if conditions are favourable and if grazing does not reduce the residual herbage mass below...

Organic farming has expanded rapidly in Europe during the last decade. In view of the agricultural policy trends, the current socio-political climate and a continuously growing demand for organic products, a further expansion of organic farming seems likely. In view of these prospects, the objective of this study is to provide a quantitative assessment of the impacts of a significant expansion of organic farming in the European Union on agricultural production, markets and the environment. Using and extending the EU-wide agricultural sector model CAPRI, different policy scenarios for a conversion of organic farming to 20 % of the agricultural area in the EU are analysed. The results indicate that such an expansion has a significant effect on several...

Autores: Probst, Johanna Karolina; Spengler Neff, Anet; Leiber, Florian; Kreuzer, Michael; Hillmann, Edna.
Die arbeitsextensive Mutterkuhhaltung hat in den letzten Jahren in der Schweiz erheblich zugenommen. Der direkte Kontakt zwischen Mensch und Tier, wie er bei der Haltung von Michkühen durch das tägliche Melken stattfindet, ist in der Mutterkuhhaltung um ein vielfaches vermindert. Eine Folge davon sind oftmals sehr scheue Tiere, die nicht selten ein aggressives Verhalten gegenüber dem Menschen zeigen. Einige Studien haben bereits gezeigt, dass eine taktile Behandlung durch den Menschen das Wohlbefinden der Tiere und gleichzeitig den Umgang mit den Menschen verbessern kann (siehe z.B.: Krohn et al., 2001, Lensink et al., 2000). In der vorliegenden Studie sollten junger Kälber aus der Mutterkuhhaltung einer taktilen Behandlung unterzogen werden. Die...

Die integrierte Biogaserzeugung in Ökobetrieben zieht vielerlei agronomische Auswirkungen auf das gesamte Betriebssystem nach sich. Herkömmliche Wirtschaftlichkeitsanalysen vernachlässigen jedoch das ökonomische Potential dieser Effekte. Dieser Beitrag verfolgt daher einen ganzheitlichen Bewertungsansatz, der diese monetären Zusatzleistungen mit einbezieht. Modellsimulationen ökologischer Fruchtfolgesysteme, die insbesondere eine veränderte Stickstoff-Effizienz berücksichtigen, zeigen mögliche Ertragssteigerungen der Marktfrüchte und eine verbesserte Wirtschaftlichkeit des Ackerbaus durch die integrierte anaerobe Vergärung sowohl in viehlosen als auch in viehhaltenden Ökobetrieben auf.

In a field experiment at the Experimental Farm for Organic Farming in Northern Germany, the effect of sulphur application in the form of MgSO4 to a red clover-grass mixture was measured in the year 2011. At the beginning of the vegetation period in the spring plots were fertilised with 30 and 60 kg S ha-1. The sulphur fertilisation resulted in significantly higher fresh weight and dry matter yields and otherwise in a lower dry matter content as compared to an unfertilised treatment. The content of crude protein and sulphur were significantly increased by sulphur application. The N/S-ratios in the fertilised plots showed values below the threshold of 15 for an adequate supply of sulphur. The N-withdrawals added up over the three cuts increased in the...

Autores: Böhm, Herwart.
Due to the high nitrogen requirements, oil seed rape should be cultivated after rye-grass-clover mixtures (Böhm 2007). But in this case oil seed rape is in competition with wheat, because wheat has a high N-requirement as well. So, the crop rotation must be organized in another way, so that there is no competition between oil seed rape and wheat. In two-year field trials at the experimental farm of the Institute of Organic Farming (FAL) in Trenthorst the hypothesis was tested, whether oil seed rape with an undersown white clover is a better preceding crop to wheat compared to oil seed rape without underseed. Additionally, the yield was compared to “wheat after ryegrass-clover mixture”. The results showed a higher yield of wheat after oil seed rape with...

The reduction of soil tillage intensity is of special interest for organic farmers. To study the influence of reduced tillage on soil properties and weed vegetation field plots were set up in 1992 on the FAM Research farm in southern Germany. From 1999 till 2002 weed vegetation was recorded including soil seed bank, plant density, number of flowering plants and biomass. Reduced tillage intensity did not influence the weed population dymamics but did influence the species composition. Elymus repens, Apera spica-venti and Poa annua were promoted by a tillage regime that omitted deep ploughing in four of seven years. The cultivation of grass/ley mixtures plays an important role in crop rotations of organic farming systems e.g. as part of the weed management....

It is the aim of the present study with 93 organic fattening pigs of varying Duroc gene portion (0 %, 25 %, 50 %, and 75 %) to deduce the optimal Duroc gene percentage.  Increasing Duroc gene portions resulted in an impaired feed conversion ratio, decreasing lean meat content, and increasing intramuscular fat content. It is concluded that in a carcass quality based marketing system Duroc gene percentage should not exceed 50 %, whereas already 25 % Duroc gene portion significantly promotes meat quality. Only for marketing systems very strictly based on meat quality Duroc gene portion should have 75 % due to a significant promotion of intramuscular fat content.

The aim of the present study including 190 organic fattening pigs of varying Duroc gene portion (0 %, 25 %, 50 %, and 75 %) was to analyze various meat and fat quality characteristics in order to deduce the optimal Duroc gene percentage in relation to different marketing goals. Increasing Duroc gene portions resulted (i) in increasing intramuscular fat contents, (ii) in improved meat quality characteristics (sensory properties, pH, electrical conductivity), (iii) in slightly increasing levels of saturated fatty acids, and (iv) in decreasing levels of mono-unsaturated fatty acids. It is concluded that Duroc gen portion should exceed 50 % only in marketing systems with a payment system including meat quality criteria.

Autores: Schneider, Regina; Heiles, Eberhard; Salzeder , Georg; Wiesinger, Klaus; Schmidt, Martin; Urbatzka, Peer.
In Fruchtfolgen im ökologischen Landbau wirken sich Unterschiede bei Anteil, Nutzung und Art der Leguminosen verschieden stark auf die nachfolgenden Marktfrüchte aus. Deren Erträge werden durch das Betriebssystem (viehhaltend oder viehlos) und die Position der Marktfrucht nach der Leguminose beeinflusst. Zur Untersuchung der Auswirkungen wurden seit 1998 im oberbayerischen Puch fünf verschiedene Fruchtfolgen angebaut und auf Ertrag und Produktivität geprüft.   Bei der Produktivität zeigten sich deutliche Unterschiede, auch davon abhängig ob die Leguminosen in die Bewertung einbezogen wurden. Der ausschließliche Anbau von Marktfrüchten mit einer Körnerleguminose statt Kleegras führte zu deutlichen Mindererträgen der folgenden Marktfrüchte. Die höchste...

Infections with diseases like black scurf (Rhizoctonia solani) and common scab (Strep-tomyces scabies) cause tuber blemishes. In addition, black scurf has an adverse impact on tuber yield, size and shape. The aim of the study was to assess the effect of combinations of main and catch crops on tuber yield, quality and sanitary status. The tested variants were: var. 1: pea without a catch crop apart from volunteer peas, var. 2: pea with a catch crop consisting of white mustard, California bluebell and volunteer peas, var. 3: oat without a catch crop, var. 4: oat with an underseed of white clover. Although in the variants tested no significant difference was achieved for tuber yield, disease occurrence and degree of infection with black scurf and common scab,...

Fodder legumes, like lucerne, make a significant contribution to a positive humus balance and nitrogen supply on organic farms. To determine the required lucerne percentage to meet these targets, several shares of lucerne were modelled on the basis of empirical data of an eight-field crop rotation. The lower limit for ensuring optimum humus and nitrogen supply in this rotation was approximately 17 % lucerne. The calculation of the data was performed with the agricultural software REPRO.

The effect of different preceding crops and fertilisation systems on winter wheat yieldand quality was assessed in a long-term field experiment in Eastern Austria. Winter wheat following a 2-years lucerne crop had lower yield but higher protein content than winter wheat following peas. Lucerne green manure use in a stockless system increased yield and protein content of a subsequent wheat crop compared to a livestock-keeping system with removal of the lucerne crop for fodder use. Wheat following peas that had received farmyard manure in the livestock-keeping system only, showed higher yield than in the stockless system but no differences in protein content. Likewise, an additional compost fertilisation in the stockless system increased yield of wheat...

Provedor de dados: 21
Autores: Gollner, Manfred; Friedel, Jürgen; Freyer, Bernhard; Hampl, Ulrich.
Problemstellung/Ziele:Die arbuskuläre Mykorrhiza ist eine Symbiose zwischen dem Grossteil der landwirtschaftlichen Kulturpflanzen und bodenbürtigen Pilzen. Der heterotrophe Pilz erhält Assimilate von der autotrophen Pflanze, als Gegenleistung fördert der Pilz die Nährstoffaufnahme in die Pflanze und erhöht die Resistenz gegenüber phytopathogenen Mikroorganismen, die in einer Wachstumssteigerung der Pflanze resultieren können. In zahlreichen Untersuchungen wurde festgestellt, dass mechanische Bodenbearbeitung das Besiedelungspotenzial von landwirtschaftlichen Kulturpflanzen durch arbuskuläre Mykorrhizapilze (AMP) vermindert und die Effizienz des Myzels der AMP bei der Aufnahme von Phosphor mit steigender Intensität der Bodenbearbeitung abnimmt.

Short rotation alley cropping can affect biodiversity and ecosystem services. Thus the epigeic fauna was investigated in different distances from a strip with short rotation poplar cultivation at two sites in Bavaria. An increase of carabid beetle diversity on field-scale was noted due to the appearance of adapted carabid species inside the strip, however with no distinct correlation between distance from poplar strip and carabid species diversity. Slug activity density decreased with increasing distance.

Autores: Bacanovic, Jelena; Šišić, Adnan; Bruns, Christian; Finckh, Maria R.
Foot rot is an important limiting factor in pea production in Germany (Pflughöft, 2008). The disease is caused by a pathogen complex consisting of Ascochyta complex pathogens (Mycospharella pinodes, Phoma medicaginis and Ascochyta pisi) and Fusarium spp. However, little is known about the specificity of single pathogens of the complex and their impact on plant performance. In order to address this problem pot experiments with five isolates each of Fusarium solani f.sp pisi, Fusarium avenaceum and Mycosphaerella pinodes were carried out in controlled conditions. Three weeks after sowing and inoculation disease symptoms were assessed and plant growth parameters measured. All pathogens caused root discoloration and development of disease symptoms on pea...

Autores: Johns, Julia; Mück, Ulrich; Knierim, Ute.
Auf 36 Betrieben wurden Auswirkungen von Herdencharakteristika, Haltungs- und Managementbedingungen auf hornbedingte Schäden bei behornten Milchkühen im Laufstall analysiert. Nach univariabler Vorselektion von potenziellen Einflussfaktoren wurden multiple lineare Regressionsmodelle angewandt. Im Grundsatz nahmen hornbedingte Schäden/Tier mit steigendem Behornungsgrad zu. Dennoch gab es auch voll behornte Herden mit sehr wenigen Schäden/Tier. Die Bedeutung der Rasse, des Fütterungs- und Eingliederungsmanagements für die Prävention hornbedingter Schäden wurde unterstrichen. Diese Faktoren zeigten häufiger einen Einfluss auf die Tiere als haltungsbezogene Aspekte.

The earthworm fauna was investigated in 2011, 2013 und 2015 on two organically managed fields of agroforestry systems in Bavaria with poplar strips established in 2009. The abundance and biomass of earthworms in the field surrounding the poplar strip were more affected by different agricultural management measures and weather conditions than by the poplar strip itself. At one site the abundance of endogeic species in the soil of the poplar strip increased while the total biomass and the abundance of Lumbricus species (almost exclusively the anecic species Lumbricus  terrestris) decreased. In addition, at the same site in 2015 a lower total earthworm biomass was detected up to 10 m into the adjacent field, due to a low abundance of Lumbricus species....

During the pre-slaughter period cattle experience novel environment and procedures causing reduced welfare and stress. This period involves a number of critical  situations: loading, transport, unloading, meeting unfamiliar animals, fixation. Therefore, stress is an inevitable consequence of transporting animals from a farm to the abattoir. In Switzerland, the first farmer recently started with a stress reducing cattle slaughter method within a pilot project: the slaughtering via gunshot on farm. Only the carcass has to be transported. Usually direct marketing farmers are transporting single animals to the next small-scale slaughterhouse. Therefore those two slaughter methods were compared regarding stress related parameters. Slaughtering always took place...

Using biomass from intercrops as feedstock for biogas production makes it possible to produce renewable energy without compromising food production. In order that using intercrops for biogas and fertilizing with liquid digestate is sustainable, it must be secured that this practice does not have adverse effects on soil fertility. Two-year randomised field experiments were conducted on two different soil types near Bruck/Leitha (A). On chernozem soil, soil pH and composition of the cation exchange complex were hardly influenced by liquid digestate. Also on a parachernozem with pH 5.9 short-term effects of liquid digestate were small due to the low salt content and high C/N ratio of the digestate. Nevertheless the distinct increase in soil K content shows...

Authenticity tests of organic products (Golden Delicious and Elstar) applying sensory analysis
Provedor de dados: 21
Autores: Ploeger, Prof. Dr. Angelika; Roeger, Monika; Weibel, Dr. Franco.
In the governmental funded project BÖL-02OE170/F, apple samples from different farming systems (organic and conventional) were differentiated and classified by sensory evaluation. Samples from farm pairs derived from geographical neighbouring locations. Each farm pair consisted of one farm producing apples according to organic land use system and one producing conventionally. Factors of influence as growing conditions, climate, soil and harvest time were comparable within each pair.  For sensory evaluation, a descriptive analysis panel was trained according ISO-standards of descriptive analysis. The quantitative descriptive analysis method (QDA) enables to show a complete product profile with all sensory characteristics of a product as well as their...

Autores: Kahl, J.; Birlouez, I.; Busscher, N.; Ploeger, A.
Consumer demand for healthy, safe and high quality food is increasing. Against this  background, the demand for organically grown food has been growing rapidly. Organic  farming contains the whole food chain from field to fork. An analyse system to optimise  the process needs to be established (QualityAnalysisCriticalControlPoint). The aim  of the transnational CORE-Organic QACCP project is a chain analysis which addresses  the link between farm and fork and backwards from fork to farm. The objective is  to improve product related quality management in farming and processing. The results  presented here are dealing with food authenticity on farm level through biocrystallization  measurements and food safety through pesticide residue and nitrate...

Authentizität von Milch und Fisch – Erkennung von Bioprodukten im Labor
Provedor de dados: 21
Autores: Molkentin, Joachim.
Die Nachfrage nach Bio-Lebensmitteln ist in Deutschland in den letzten Jahren stetig gestiegen. So erhöhte sich der Absatz von Bio-Trinkmilch in 2007 im Vergleich zum Vorjahr erneut um 34 %. Aufgrund sporadisch resultierender Lieferengpässe bei Bio-Milch aber auch der erheblichen Handelspreisdifferenz – wie z. B. insbesondere bei Bio-Lachs – besteht ein potenzielles Risiko der Falschdeklaration konventioneller Produkte als Bio-Ware.  Zum Schutz von Verbrauchern wie auch Erzeugern werden daher Verfahren zur Überprüfung der Kennzeichnung benötigt, die – in Ergänzung der betrieblichen Kontrollen – im Zweifelsfall eine Unterscheidung ökologisch und konventionell erzeugter Lebensmittel auf Ebene des Einzelhandels erlauben.

Autores: Staub, S.; Brell, S.
Weed management without herbicides in production of field vegetables is very time consuming and therefore costly. After every mechanical treatment a weeding by hand is necessary for a satisfactory weed control. To minimize the weeding automatic  steering systems connected to a shifting frame can support the mechanical weeding by making it more precise and reducing the remaining weeds in the row. Field studies in the year 2016 showed advantages and disadvantages of the systems.

Autumn applications of sulphur – a new approach to control the pear leaf blister  mite Eriophyes pyri
Provedor de dados: 21
Autores: Daniel, Claudia; Linder, Christian; Wyss, Eric.
The pear leaf blister mite can cause severe damages to pear trees. By their hidden way of living inside  the leaf blisters, the mites are protected from plant protection agents. Until now, oil treatments  in early spring, when the mites leave their hibernation sites and invade the young leaves, are the  only possibility to control these mites. Because of the low temperatures during this period (February/  March) the efficacy of pesticides is often not reliable. The aim of this study was to assess the effects  of sulphur applied after harvest at the time, when mites are leaving the blisters and migrate to  the hibernation sites. The treatments were applied shortly after harvest to benefit from the mild temperatures  in September. Visual controls in...

Backqualität von Winterweizen in Bio- und Extenso Prüfungen
Provedor de dados: 21
Autores: Kleijer, Dr. G.
Winter wheat trials have been carried out from 2002 to 2007 under extensive or organic  conditions. The results of baking quality analyses have been compared for the  same varieties, cultivated under both conditions during the same year. Rheological  analyses generally show lower results for the varieties cultivated under organic conditions  when baking tests result nearly identical in both networks. Wet gluten is an  important baking quality parameter for the users. The percentage of wet gluten is not  correlated with the gluten index, the extensographe energy or the points obtained by  the baking tests. This parameter alone cannot be used for determination of the baking  quality.

Bait sprays against the European cherry fruit fly Rhagoletis cerasi: Status Quo &amp; Perspectives
Provedor de dados: 21
Autores: Köppler, K.; Kaffer, T.; Vogt, H.
Bait spray experiments against Rhagoletis cerasi were carried out in 2005 to 2007. The  main principle of this method is to use food (e.g. sugar and proteins) as baits for the flies  with small amounts of insecticides, which is applied on parts of the cherry tree. Main focus  was aimed at laboratory and field cage experiments using the commercial GF-120  Naturalyte Fruit Fly BaitTM with the insecticide spinosad, which is registered against North  American cherry fruit fly species in the US and Canada. Furthermore, additional bait spray  formulations as alternatives to GF-120 were used to define the right food bait quality for a  high attractiveness and low reproduction ability. Beyond, the negative effect on  reproduction of flies for azadirachtin (neem)...

In 2005 initial experiments were carried out to control Rhagoletis cerasi with bait sprays. We used GF-120  fruit fly bait which contains Spinosad and NeemAzal®-T/S mixed in a sugar-yeast hydrolysate solution. 30 ml  of bait sprays were applied on single cherry trees in field cages, where we released a defined number of  cherry fruit flies. One experiment with GF-120 resulted in a reduction of fruit infestation of 96 % compared  with the control. In other trials with GF-120 and Neem bait the effect on the cherry fruit fly population was  monitored. After 24 hours GF-120 in a 5 % and 20 % solution led to a high reduction of flies (efficacy 85 %),  whereas NeemAzal®-T/S in a 5 %, 10 %, and 20 % solution only resulted in efficacies between 34 % and  42 %.

Balancing fertilization strategy with crop requirements in organic greenhouse cultivation of sweet pepper
Provedor de dados: 21
Autores: Cuijpers, W.J.M.; Voogt, W.; Koopmans, C.J.
An on-farm field trial was set up in an organic greenhouse in order to balance the N-uptake by a sweet pepper crop and the mineralization of the organic fertilizers was applied. The effects of six fertilizer treatments were compared regarding yield, nutrient availability and mineral balance. Application of high levels of compost turned out to be favourable in order to reduce surplusses of available-N on the short term. On the long term, such high levels of compost are unfavourable as a high pool of mineralizable-N in the soil organic matter restricts the possiblities for precise fertilization adapted to plant uptake. Application of lower levels of farm yard manure in combination with additional fertilization with feathermeal turned out to be a good...

Balancing soil organic matter in organic agriculture - a theoretical approach
Provedor de dados: 21
Autores: Brock, Dipl.geogr. Christopher; Leithold, Prof.Dr. Günter.
Soil organic matter (SOM) balances can assist sustainable organic matter management. Still, existing methods need to be revised, especially when applied in organic farming. A basic problem is the linear concept which seemingly does not reflect the effective dynamic.  Furthermore the relevance of SOM is dependent on the cultivation system and cultivation intensity, respectively. The importance of SOM as a nutrient source increases with diminishment of cultivation intensity, i.e. synthetic fertilizer application. Here turnover of organic matter becomes the key factor for nutrient supply.  Correspondingly, a higher SOM reproduction level that promotes increased SOM content and/or turnover should be an objective in organic farming.  Soil organic matter...

Band-steaming for intra-row weed control
Provedor de dados: 21
Autores: Melander, Bo; Heisel, Torben; Jørgensen, Martin Heide.
Steaming the soil prior to crop sowing has the potential of eliminating weed seedling emergence completely. Thus, steaming might be a perspective technique for intra-row weed control in non-herbicidal row crops of high value, where manual weeding can be very laborious. This paper presents some preliminary results with the effects of steaming on weed seedling emergence. The work is part of a joint project involving both biological and technical aspects of steaming. The overall objective is to develop an applicable technique for applying steam in bands corresponding to the intra-row area of a row crop. Band-steaming is expected to use much less energy as compared to current steaming techniques for arable usage.

Barriers for developing more robust organic arable farming systems in practice
Provedor de dados: 21
Autores: Noe, E.; Sørensen, P.; Melander, B.; Olesen, J.E.; Fog, E.
There is a gap between the scientific idea of robust and economically viable organic arable farming systems with optimized crop rotations for nutrient and pest management and how these systems look like in practice. In order to explore this gap, we visited and interviewed ten organic arable farms in Denmark. Our main findings are: 1) Organic arable farming operates in a very dynamic and changing environment in terms of prizing and market opportunities, and the main focus of the farm managements was the coping strategy within this changing environment; 2) The farming systems were continuously changing and developing, buying and renting more land, changing manure agreements and other forms of cooperation and arrangements; 3) Short term profit was paid much...

Barriers to the adoption of organic agriculture An investigation using the Theory of Planned Behaviour
Provedor de dados: 21
Autores: Hattam, Caroline.
Certified organic production by small-scale farmers in developing countries is increasingly promoted as an opportunity to access a growing and dynamic market while at the same time, enhance productivity and improve incomes. Nevertheless, adoption has been slow. The economics literature suggests profitability is the main constraint; however, the sustainable agriculture literature is inconclusive and considers attitudes of significant importance. As ecological behaviour is susceptible to a wide range of influences beyond an individual’s control, environmental attitude alone is often a poor predictor of behaviour (Kaiser et al., 1999). The Theory of Planned Behaviour (Ajzen, 1985) is therefore promoted for studies in the ecological domain as in addition to...

Basic results in biological control of the European Cherry Fruit Fly Rhagoletis cerasi L. (Diptera: Tephritidae) with entomopathogenic nematodes
Provedor de dados: 21
Autores: Köppler, Kirsten; Peters, Arne; Vogt, Heidrun.
In 2002 and 2003, within the ‚Bundesprogramm Ökologischer Landbau’, initial experiments to control  the European cherry fruit fly Rhagoletis cerasi were carried out under laboratory, semi-field and  field conditions with several entomopathogenic nematode species and strains. In the laboratory the  efficacy of nematodes against R. cerasi larvae, pupae and adults was examined. To characterize  the controlling potential, different nematode dosages, exposure temperatures and substrates were  tested in cell wells, petri dishes and plastic boxes. In the semi-field experiments plastic fruit boxes,  filled with soil, were used. In the field tests R. cerasi-larvae and nematodes were released in defined  areas in a cherry orchard of the institute. For evaluation of...

Bäuerliche Experimente in Kuba und ihre Bedeutung  für eine nachhaltige Landwirtschaft
Provedor de dados: 21
Autores: Leitgeb, Friedrich; Kummer, Susanne; Vogl, Christian R.
This paper aims to examine farmers’ perception on the contribution of farmers’ experiments to sustainable agriculture. Field research was conducted in Cuba and comprised semi-structured interviews with 72 farmers. Most Cuban farmers experimented with locally available resources. According to the farmers’ perception, resources, topics and methods were ecologically compatible and involved little risks. Through experimenting the respondents felt, that they increased the production and the degree of self-sufficiency. Farmers ensured that experiments contributed to improve the local farming system and thereby supported the sustainable development of agriculture.

Autores: Hermann, J.; Behrendt, S.; Kusche, Daniel.
The farm effect, reported in more than 40 studies, is associated with the more wellknown hygiene hypothesis. In particular the early consumption of untreated milk in a  human's life may, besides genetic predisposition, impact the immune system of children and may prevent atopic diseases in their whole lifespan. Due to the special role of untreated milk, the question was answered, which milk causes a remarkable farm effect. There is evidence for differences between effects of treatment degrees of milk as well as its organic and conventional origin. These findings were evaluated before the background of organic agriculture by comprehensively reviewing existing interdisciplinary literature including medicinal studies and by conducting an expert interview.

Beating the economies of scale through local food
Provedor de dados: 21
Autores: Dvortsin, Leo.
Often local and organic food producers and their supply chains face two main challenges: high logistical costs and complex distribution, and estab-lishing lasting relations with the consumers. Conven-tional supply chains drive the costs down through benefits of economies of scale and have therefore a competitive advantage over the small initiatives. At the same time the conventional supermarket chains are part of a bigger food system and cannot efficiently meet changing consumer demands. This creates a window of opportunity for the local and organic food enterprises such as the Dutch Willem&amp;Drees case study shows. In order to seize this opportunity new ways of cooperation and communications are needed. This means creation of short food supply chains...

Beauveria bassiana strain ATCC 74040 (Naturalis®), a valuable tool for the control of the cherry fruit fly (Rhagoletis cerasi)
Provedor de dados: 21
Autores: Ladurner, E.; Benuzzi, M.; Fiorentini, F.; Franceschini, S.
Naturalis® is a bioinsecticide based on living conidiospores of the naturally occuring  Beauveria bassiana strain ATCC 74040. The entomopathogenic fungus acts primarily by  contact: once attached to the insect’s cuticle, the conidiospores germinate producing  penetration hyphae, which enter and proliferate inside the insect’s body. The fungus  invades and feeds on its host, causing its death due to dehydration and/or depletion of  nutrients. Several years of laboratory, semi-field and field studies showed that also Tephritid  flies (Ceratitis capitata, Rhagoletis cerasi, Bactrocera oleae) are susceptible to infection by  B. bassiana strain ATCC 74040. The results of efficacy trials conducted in 2004-05 are  reported. Naturalis was tested both alone and in...

Autores: Saastamoinen, Markku.
Choose of the bedding material is important especially in the Northern climate conditions, because  the horses are kept most part of the day and year indoors during their life. Especially, the effect of  the bedding material on the quality of the stable air is of great importance. Based on their  properties, it seems that peat and straw pellets are the most suitable beddings for horse stables. Also  pelleted newspaper seems to have a good potential as a bedding material.

Bedeutung der funktionellen Einheit für die Ökobilanzierung in der Landwirtschaft
Provedor de dados: 21
Autores: Guggenberger, T.; Herndl, M.
Life cycle assessment (LCA) gains increasingly in technical and legal importance. Research groups getting involved with this topic have to adhere to the technical standard. The definition of appropriate reference values, indicated as functional units, is of special importance in this concern. LCA is often derived from the industrial sector, where it is one-dimensionally treated via output of companies. In the agricultural sector at least the problem of land use management has additionally to be considered. This paper shows the development of a convenient solution for this purpose in agricultural consultancy.

In the experimental station of the Thünen-Institute of Organic Farming the dairy breeds Holstein-Friesian (SBT) and Red Holstein double usage (RBT) are kept in separate herds under identical conditions. By means of a material flow FARM-Model, designed with the life cycle assessment (LCA) and material flow software Umberto, an assessment from cradle to farm gate of standard environmental impact categories was undertaken. While the BH has a better environmental performance due to higher milk yields the results depend largely on used algorithms in the model. When benchmarking different farms in terms of environmental performance modeling uncertainty has to be taken into account.

In a field experiment at the Experimental Station for Organic Farming Kleinhohenheim the effect of stubble tillage has been assessed over a period of five years. Perennial weeds were effectively controlled by stubble tillage. Annual weeds were not affected when considering the above ground populations. Shallow ploughing revealed no better effect than the other implements tested. The results show that stubble tillage is very important for the control of perennial weeds in Organic Farming. A renaissance of the shallow plough appears not to be necessary.

Outside the breeding season, densities of raptors (in autumn and in winter), seed-eating birds (in autumn) and insect-eating birds (in autumn) were significantly higher on organic than on conventional plots. Organic fields more often held stubbles and/or green vegetation in the non-breeding season. On organic farms, carnivorous birds had significantly higher densities both on fields with stubbles and green vegetation. Granivorous birds had significantly higher densities on stubble fields and insectivorous birds had higher densities on fields covered by green vegetation. There was a signifi-cant positive correlation between density of seed mass and density of granivorous birds.

In a one-year study in Northern Germany, we analyzed the effects of unsown fallow strips and landscape heterogeneity on the segetal flora of organically managed sandy fields. Diversity of plants was higher in two/three-year-old fallow strips compared to reference sites tilled with winter rye. Concerning endangered species, this effect was more pronounced in fields that were in a small-scale than in a homogenous landscape, as the latter possibly featured less colonization potential.

Close seeding of field beans (Vicia faba) has been regarded for several years as an option in organic agriculture for the short-term introduction of nitrogen into production systems. At the same time faba bean potentially supplies nitrogen (N) to crops and soil by N2 fixation and nitrogen release when crop biomass is finally mulched. The main objective of this project was to investigate and develop a method of N-supply to meet the demand of broccoli using organic N-sources. Based on the results it can be stated that yield of broccoli significantly increased in the treatment intensive legume cropping plus fertilizer when compared to an intensive legume cropping without horngrist. However, upon inspection, it was revealed that marketable yields were even...

Autores: van der Heijden, Marcel; Wagg, Cameron; Lukasiewicz, Kasia; Olbrecht, Luise.
Grass-clover pastures form an essential part of organic farming systems. It is well known that nitrogen fixing bacteria play a key role in determining productivity of grass-clover pastures. Yet, the impact of other plant symbionts, such as arbuscular mycorrhizal (AM) fungi, on grass-clover is still poorly understood. Here we demonstrate that AM fungi enhanced red clover biomass and enabled red clover to coexist with grass. Moreover, the diversity of AM fungi in the soil promoted productivity of grass-clover mixtures. Inoculation experiments in a range of field soils with native AM fungi showed that addition of AM fungi promoted clover biomass in several (but not all) soils. This study shows that AM fungi can be important for clover establishment in pastures.

One consequence of the BSE-crisis is, that animal residue derived N-fertilisers used in organic horticulture are to be replaced. As an alternative plant derived N-fertilisers have been investigated. In an incubation experiment these fertilisers mineralised 40 to 60  % of the total N applied. Net N-mineralisation in the incubation experiment as well as plant N-utilisation in a pot experiment were closely related to the N-content of the fertilisers. Fertilisers increased the N-uptake of plants in any soil. Neither texture nor the content of Corg explained the observed differences in fertiliser use efficiency .

Beeinflusst die Bewirtschaftung das Vorkommen von Jakobskreuzkraut (Senecio jacobaea)?
Provedor de dados: 21
Autores: Suter, Matthias; Siegrist-Maag, Sandra; Luescher, Andreas.
Senecio jacobaea is a poisonous weed in grasslands of various countries (e.g. Great Britain, New Zealand, Central European states), and the further spread of the species into farmland must be prevented. Due to strong restrictions of curative measures, the prevention of S. jacobaea’s spread is of primary importance for organic farming. To assess the influence of management practice and site conditions on the occurrence of S. jacobaea, we conducted an on-farm survey in the northern and central part of Switzerland. Botanical assessments were carried out on grassland plots with S. jacobaea occurrence and on neighbour plots without S. jacobaea. For these plots, we analysed the soil nutrients and the details of management practice such as type and intensity of...

Beeinflussung der generativen Vermehrung von Rumex obtusifolius durch produktionstechnische Maßnahmen
Provedor de dados: 21
Autores: Pekrun, Carola; Hofrichter, Veit; Link, Johanna; Thymian, Frank; Thumm, Ulrich; Claupein, Wilhelm.
Rumex obtusifolius produces a large number of long living seeds. Therefore, all means to reduce seed production or establishment of seedlings from seeds are impor-tant. The data of this paper show that in grassland a high soil seed bank not necessar-ily leads to a high infestation with dock. There are options to interfere seed production and establishment of seedlings. The cutting regime may have an impact on seed production. Establishment of seedlings can be minimized by avoiding gaps in the vegetation canopy.

Bees as entomovectors and the biological control agent Gliocladium catenulatum J1446
Provedor de dados: 21
Autores: Muljar, Riin; Mänd, Marika.
There is a need for more environmentally friendly plant protection methods, since the increasing use of agrochemicals has led to pesticide residues and resistance problems in the control of Botryrtis cinerea. An alternative to chemical spraying is to use bees as entomovectors to disperse biological control agents. Prestop Mix is a biofungicide that contains spores of the parasitic fungus Gliocladium catenulatum J1446, which has been successfully used in the control of B. cinerea. In 2010 we conducted a field experiment to study the efficiency of using bees in dispersing G. catenulatum in Estonian conditions. The study was carried out in two strawberry plantations of Tartu County, strawberry varieties were `Sonata` and `Polka`. Honey bee hives were placed...

Autores: Hörning, B.; Aigner, S.; Aubel, E.; Schubbert, A.; Simantke, C.; Bussemas, R.; Trei, G.
Fazit:    Die gegenüber früheren Untersuchungen gestiegenen Bestandsgrößen weisen darauf hin, daß sich im ökologischen Landbau ein ähnlicher Strukturwandel wie in der konventionellen Landwirtschaft vollzieht (Wachstum und Spezialisierung). Die Auswertung zeigt ferner, daß die Betriebe zunehmend bemüht sind, bereits jetzt den zukünftigen Haltungsvorschriften der EU-Verordnung zu entsprechen. Fast alle Betriebe führen Weidegang durch und trotz der relativ geringen Bestandsgröße haben die meisten Betriebe bereits Laufställe; Auslaufmöglichkeiten fallen demgegenüber allerdings noch ab.

(Tagungsbeitrag Pferdenetzwerktagung, Avenches).  Das Equine Sarkoid ist der häufigste Hauttumor des Pferdes. Bisher gilt keine konservative The-rapie als ausreichend wirksam und nach chirurgischer Entfernung sind oft Rezidive zu beobach-ten. Schon seit vielen Jahren wird die Mistel in der Human- und Kleintiermedizin als begleiten-des Krebstherapeutikum erfolgreich eingesetzt. Erste Erfahrungen zeigen auch bei Hauttumoren des Pferdes Erfolge. Im Rahmen einer placebokontrollierten Blindstudie wird daher seit März 2004, im Nationalgestüt Avenches, das Mistelpräparat IscadorR zur primären Behandlung von Sarkoiden und zur postoperativen Prophylaxe gegen Rezidive auch beim Pferd geprüft.

Homeopathic remedies are means to an end. Success of treatment depends not only on the efficacy of remedies, but also on the prerequisite in terms of availability of  expertise and appropriateness of the treatment procedure. To assess the extent by which a lege-artis treatment concept in homeopathy is performed in treating mastitis, a study was conducted on 64 mainly organic farms in Germany, France and Spain. The study revealed that most farmers only had a poor level of awareness of the principles of homeopathy and made use of human products regularly without rededication by a  veterinarian or made use of forbidden substances. Treatments were accompanied by insufficient follow-up checks. Homeopathic treatment procedures were applied very  heterogeneously....

Autores: Langford, F; Rutherford, K; Sherwood, L; Jack, M; Haskell, M.
There is an increasing number of organic dairy farms in the UK. The aim of this study is to compare behaviour of dairy cows on organic and non-organic farms. Twenty organic and 20 non-organic farms throughout the UK were visited over two winters (2004/05 and 2005/06). Organic and non-organic farms were paired for housing type, herd size, milk production traits and location. The number of cows feeding was counted every fifteen minutes for 4.5 h after new feed was available post morning milking. Behaviour at the feed-face was recorded for 60 minutes and aggressive interactions between cows were quantified. Farm type had no effect on numbers of cows feeding. There were more interactions between cows feeding at open feed-faces compared to head-bale barriers....

Beisaat von Zwischenfrüchten als Möglichkeit zur Reduzierung der N-Auswaschung in Wintergetreide?
Provedor de dados: 21
Autores: Loges, Dr. Ralf; Mauscherning, Inken; Taube, Prof. Dr. Friedhelm.
In a field experiment the potential of mixtures of winter cereals and catch crops to reduce nitrate leaching was investigated. Pure winter wheat showed the highest N-losses (56 kg N ha-1). Compared to a control without a catch crop, winter rye and oilseed radish grown in pure stand or in mixture with a winter cereal reduced nitrate-leaching by 30 to 80 %. However, common vetch had a significant lower potential compared to the tested non-legume catch crops. Further investigations are needed to optimize the system with special regards to the concurrence between cereal and catch crop in autumn and in early spring.

Autores: Simon, Jochen; Stötzel, P.
Due to the increasing demand for organic dairy products and the running out of the transitional period of the EG-Regulation on Organic Farming 1804/1999 in the year 2010 many farmers must decide to build new barns. Two examples from Bavaria are given as a prospect of the conception and the development of barn buildings. The cow kennel of Küfner – Naiser is significant for its arrangement of two unroofed yards within the barn. The flat extensive roof planting of the Haneberg barn works as buffer for extreme changes of temperature. It is also remarkable for its sophisticated integra-tion of the existing building into the new conception.

Fusarium graminearum (FG) is the most prevalent Fusarium Head Blight (FHB)  fungus in Switzerland. In conventional agriculture, fungicides are used to reduce the  risk of FHB infection and mycotoxin contamination of wheat. As an alternative for  organic wheat production, we examined plant-based products that showed antifungal  effects from our previous late blight field trials. In bioassays, the effect of these  antifungal plant preparations (APP) was screened against FG. In 2006 and 2008, the  most active APP, Rheum palmatum, Frangula alnus and preparations of Galla  chinensis as well as a plant substance (PSX), were used as FHB control agents in  field trials with artificial FG infections.

Snow mold, caused by the fungal pathogen Microdochium nivale, is an important  seed-borne disease of various cereals and fodder plants, leading to reduced stands  after emergence. No agricultural measures are known to prevent snow mold, hence,  direct control measures are needed. For organic agriculture, seed dressing with plantbased  products could be an alternative. In contrast to spray treatments onto the crop,  the formulation and application of plant preparations onto seeds represents a greater  challenge in terms of adhesion, persistence, and lasting efficacy. In the current study,  three plant-based powders applied with two different seed coating materials were  tested for their efficacy against MN of wheat. Both adjuvants demonstrated equally...

Provedor de dados: 21
Autores: Hallmann, Johannes; Rau, Florian; Puffert, Markus.
The root-knot nematode Meloidogyne hapla is a major pest in organic farming causing severe damage especially on vegetables. Common practices such as high cropping frequencies of legumes and low frequencies of cereals in association with unsatisfactory weed control are assumed to be major factors for nematode build-up. Due to the broad host spectrum of M. hapla strategies solely based on crop rotation are often not sufficient in controlling the nematode. A series of field experiments was conducted to develop more efficient control strategies. Based on the results a recommendation for reducing high nematode densities was developed which is build on black fallow throughout the main vegetation period buffered by additional measures such as previously growth of...

Autores: Hallmann, Johannes; Klinger, Sonja; Rau, Florian.
Plant parasitic nematodes are an increasing threat to organic farming in Germany. Especially taxa with broad host spectra and high multiplication rates such as Meloidogyne hapla and Pratylenchus spp. can cause severe damage up to total loss of the crop. The control of these nematodes is extremely difficult. Resistant cultivars are not available and only few non-host crops are known. Weed control is another important issue as most weeds are excellent hosts. In 2003 and 2004 two on-farm trials aimed at controlling M. hapla and Pratylenchus spp. were conducted in Niedersachsen, Germany. Results from these trials can be summarized as follows. For M. hapla, best control was achieved with black fallow and maize in combination with weed control. Fodder radish...

Autores: Mayer, Jochen; Oberson, Astrid; Lüscher, Andreas; Frossard, Emmanuel; Hammelehle, Andreas.
We investigated the effect of organic versus conventional cropping systems on the below ground nitrogen inputs of Trifolium pratense L., its transfer to corresponding grass and the fate in the soil organic matter in the clover-grass ley of the DOK long term experiment, Switzerland. BGN tended to be largest in conventional and organic treatments with standard fertilisation and decreased with lower fertilisation intensity. The largest amount of clover N transferred to grass was observed in the minerally fertilised conventional treatment. Clover N derived from rhizodeposition was rapidly stabilised in all treatments to clay rich fractions and thus clover N will have a relatively low direct N contribution to subsequent nonlegumes.

Provedor de dados: 21
Autores: Riffel, Alexandra; Becker, Konstantin; Leithold, Günter.
Auf den Versuchsflächen des Gladbacherhofes wurde ein Schwefeldüngungssteigerungsversuch in einem Luzerne-Kleegrasbestand im 2. Hauptnutzungsjahr angelegt (Untersuchungsjahre 2012 und 2013). Die Untersuchung sollte zeigen, in welcher Höhe eine Schwefelgabe unter den gegebenen Standortbedingungen bemessen sein soll. Eine Schwefeldüngung mit Magnesiumsulfat bewirkte generell einen Anstieg der Trockenmassebildung. Das mathematische Optimum lag in beiden Untersuchungsjahren bei einer Düngermenge von 60 kg S ha-1.

Benchmarking as a means of improving the financial wellbeing of organic dairy farms
Provedor de dados: 21
Autores: Waterfield, William.
This report was presented at the UK Organic Research 2002 Conference. Benchmarking is an important management tool enabling the comparison of actual financial data on a similar basis. Currently there is little data available on the actual costs of farming to organic standards. Limited financial or incomplete management information tends to lead to poor decision taking. The objective of the exercise is to identify the practices, which lead to enhanced financial performance, either low costs of production or high levels of profitability. The identification of these most profitable practices enables informed decisions to be made about the way the farming business needs to change. The main problem areas include the collection of detailed information broken...

BENEFICIAL AND PEST INSECTS ASSOCIATED WITH TEN FLOWERING PLANT SPECIES GROWN IN QUÉBEC, CANADA
Provedor de dados: 21
Autores: Boisclair, Josée; Lefrançois, Élisabeth; Leblanc , Maryse; Grenier, Michèle; Lefebvre, Maxime; Richard, Geneviève.
Preventive measures are very important in organic agriculture to minimize pest problems. Conservation biological control is one preventive approach. It includes habitat manipulation through which the agroecosystem may be designed to encourage the activity of beneficial insects. The use of flowering strips is one way to do that. This 3-year study was performed on the Organic Agriculture Innovation Platform in Saint-Bruno-de-Montarville, Québec. Canada. It comprises data on insect abundance and composition on ten flowering plant species. Data are collected on beneficial insects such as coccinellid predators and predatory bugs. Are also included in this study observations and counts of insect pests which could also be attracted to this flowering plant species...

Beneficial Invertebrate Activity in Organic and Conventional Vegetable Fields in Eastern England
Provedor de dados: 21
Autores: Eyre, Dr M.D.; Labanowska-Bury, Ms D.; White, Mr R.; Leifert, Prof C.
Beneficial invertebrate activity was assessed in 2005 and 2006 in three organic and one conventional vegetable field using pitfall and pan traps. Data was generated from a total of 208 trapping sites in cauliflower, leek, cabbage, purple sprouting broccoli and calabrese crops and 80 sites in planted field margins. More activity of epigeal invertebrates was found in Brassica fields compared with leek fields and there was more in organic than conventional Brassica fields. Activity of useful invertebrate groups in the field margins decreased with vegetation development and there appears to be a need for management of margins in order to optimise activity of the most appropriate beneficial groups for the crop planted.

In 1997, Iowa State University established the first U.S. Land Grant University permanent faculty position in organic agriculture to assist farmers in the rapid expansion of organic production in that state. Research agendas, developed in consultation with organic farmers and processors, led to the establishment of the Neely-Kinyon Long-Term Agroecological Research (LTAR) site in Greenfield, Iowa, in 1998 to study the long-term effects of organic production in terms of yield and economic performance, in addition to other system effects. Over nine years of comparison, there was no significant difference in corn or soybean yields in the organic and conventional systems. Organic corn yields in the longest rotation (C-S-O/A-A) over a 9–yr period were 9914...

Autores: Häring, A. M.; Dabbert, S.; Offermann, F.; Nieberg, H.
Recent food scares have lead to a boom in demand for organic products and an increasing awareness of policy makers of the potential benefits of organic farming. However, policies specifically targeting organic farming support do not remain beyond dispute and a sound justification of these is in great demand. The potential specific contribution of organic farming to the achievement of some of the key objectives of the European Common Agricultural Policy, e.g. competitiveness of agriculture, farming income, food supply, food quality and minimisation of negative environmental impacts of agricultural production are discussed.   It is argued that organic farming can contribute to the objectives of the CAP, however, addressing the various objectives to different...

Presently the value of the organic food market in Germany is approximately 5.8 billion Euros and is growing, but this growth is not reflected in the number of organic farmers. In order to raise the number of organic farmers, organic extension plays an important role. The extension system of organic farming is partly linked to the conventional system; for example organic extensionists are employed by the Chamber of Agriculture. In addition to this, a separate organic extension system exists, organized by the organic farm associations. The key questions of the study are: how to reach conventional apprentices and farmers from the organic-extension point of view, and how to enhance their decision-making authority in terms of conversion. The overall goal is...

Berücksichtigung von Bodenvariabilität bei der Kalk-Ausbringung
Provedor de dados: 21
Autores: Kling, Charlotte.
In Brandenburg ist die räumliche Variabilität der kalkungsrelevanten Bodenparameter Textur, pH und Humus so groß, dass durch Beprobungen auf 3-5 ha Teilflächen gemäß den VDLUFA-Empfehlungen Unterschiede nur unzureichend erfasst werden. Dies bedingt bei pH-anspruchsvollen Kulturen, wie Luzerne und Kleearten, heterogene Bestände und einen geringeren Vorfruchtwert. Gerade im Ökolandbau ist es daher wichtig, kleinräumige pH bedingte Probleme zu erkennen und Methoden zu entwickeln, die ortsspezifisches Kalkmanagement ermöglichen.  Im Rahmen des EIP-Agri-Projektes „pH-BB: Präzise Kalkung in Brandenburg“ kommen zwei mobile Sensorplattformen auf einem ökologischen und zwei konventionellen Betrieben zum Einsatz.

Damit wird der ökologische Landbau zum Leitbild für einen „integrierten Naturschutz“. Diesem Anspruch stehen die ökologisch wirtschaftenden Betriebe grundsätzlich positiv gegenüber. Die Umsetzung kann als betriebliche Ausgestaltung des „integrierten Naturschutzes“ verstanden werden. Trotzdem ist der Erhalt gefährdeter Biotope auch im ökologischen Landbau kein kostenloses Koppelprodukt. Die Integration einer nutztiergebundenen Biotoppflege hat erhebliche Auswirkungen für einen...

Provedor de dados: 21
Autores: Herold, Jonas; Brügemann, Kerstin; König, Sven.
Ziel dieser Arbeit war es basierend auf Betriebscharakterisierungen Betriebstypen zu identifizieren, welche in späteren Untersuchungen genutzt werden sollen, um den allgemeingültigen Betriebseffekt durch einen "Betriebstypeneffekt" im Zuchtwertschätzmodell zu ersetzen, mit dem Ziel die Sicherheit der Zuchtwerte zu erhöhen. Die Charakterisierung beinhaltete Merkmale zu Betrieb, Stall, Weide, Herdenmanagement, Fütterung, Nachzucht, Fruchtbarkeitsmanagement, den verfügbaren Arbeitskräften und dem Tagesablauf sowie detaillierte Informationen zum Herdenmanager (Bildungsstand, Weiterbildung, etc.). Insgesamt wurden 20 DSN- und 9 HF-Betriebe analysiert.

Betriebseigenes versus zugekauftes Futter für Öko-Ferkel:  Unterschiedliche Fütterungsstrategien und ihre Auswirkungen
Provedor de dados: 21
Autores: Baldinger, Lisa; Bussemas, Ralf; Höinghaus, Kathrin; Renger, Anja; Weißmann, Friedrich.
Based on organic agriculture´s aim to produce as regionally and self-sufficient as possible, animal feeding should be mainly based on home-grown feedstuff. This poses  a special challenge in feeding of piglets, who require highly digestible diets and highquality protein. Therefore, a feeding trial was conducted to compare various singlephase, 100% organic feeding strategies for piglets before and after weaning, differing in the proportion of home-grown feeds. Each strategy consisted of one out of three concentrates and one out of two roughages. The type of roughage did not affect animal performance, but the concentrate with the highest proportion of home-grown  feed and accordingly lowest quality led to significantly slower growth, while the concentrate...

Betriebsindividuelle Entwicklung von Natur und Landschaft vor dem Hintergrund der Förderkulisse - Ein Diskussionsbeitrag
Provedor de dados: 21
Autores: Wolfart, Andreas; Fuchs, Nikolai.
The present, for all parties unsatisfying governmental grant system of agricultural nature protection should be adapted in the future individual farm approaches. Methods referring to this are already developed. Instead of invariable directions given all over the country, the applicants formulate actions exactly adjusted for the special locality and the individual farm. An accredited expert attests the conformity of the plan with the laws of nature protection. Consultation is a further topic for governmental granting. All granted actions are to be made transparent to the public. This enhances private-official networks as required by the European Agricultural Convention.

Provedor de dados: 21
Autores: Tichter, Arne; Sweers , Weert; Müller, Jürgen; Dittmann, Lisa; Brinkmann, Jan; March, Solveig; Isselstein, Johannes.
Die Erzeugung hochwertiger Grobfuttermittel spielt für die Rentabilität und Nachhaltigkeit der Milcherzeugung im ökologischen Landbau eine entscheidende Rolle. Grobfuttermittel beeinflussen die Gesundheit und Leistung des Milchviehs auf verschiedene Art und Weise. Zudem variieren die standörtlichen Bedingungen des Futterbaus sowie die avisierten Leistungsniveaus der Milchviehhaltung in der Praxis erheblich (Haas et al. 2001, Brinkmann &amp; Winckler 2005, Müller-Lindenlauf et al. 2010). Ziel dieser Untersuchung ist es, die Variabilität der betrieblichen Konzepte der Grobfuttererzeugung überregional zu analysieren und etwaige Strategietypen zu identifizieren, die für weitergehende Analysen und Beratungsempfehlungen eine objektivierte Grundlage bieten.

Betriebssystematische Aspekte zur Integration der nutztiergebundenen Biotoppflege in den ökologischen Landbau
Provedor de dados: 21
Autores: Rahmann, Gerold.
In Deutschland ist die Beweidung von verbuschten Kalkmagerrasen die ethologisch beste Form der Weidehaltung von Ziegen. Gehölze stellen eine wichtige Futtergrundlage für Ziegen dar, sind bei der ökologischen Ziegenhaltung den Tieren anzubieten und damit in die Richtlinien aufzunehmen.   Durch die Beweidung von gefährdeten Biotopen mit einem hohen Verbuschungsgrad kann wird nicht nur die Tiergerechtigkeit der Weidehaltung von Ziegen erhöht, sondern auch kostengünstiger Naturschutz betrieben. Die Pflegekosten konnten um die Hälfte reduziert werden. Die Biotopbeweidung als integraler Bestandteil des ökologischen Betriebes benötigt aber ein ausgeklügeltes Weide- und Herdenmanagement, da bei der Biotopbeweidung sowohl den naturschützerischen Vorgaben als auch...

Betriebswirtschaftlicher Vergleich des Mischfruchtanbaus von  Soja und Leindotter mit dem Reinanbau von Soja
Provedor de dados: 21
Autores: Froschhammer, Peter; Siegmeier, Torsten.
Soybean production in organic farming is characterized by widely fluctuating yields,which increase the risk for farmers. One approach to counteract this is a mixed cropping system of soybean and camelina. A two-year on-farm experiment showed,  that the labour- and directcosts free output for wide yield range of soya is higher in mixed cropping compared to soya monoculture. In seasons with a low soybean yield mixed cultivation can be more effective due to the compensation benefit of camelina.

Over the past 40 years, dairy cow breeding has led to very high yielding cows (more than doubled average annual milk yields in most dairying countries), but also to a deterioration in cow health, fertility and longevity (Pryce et al. (1999)). Consequently, many breeding organizations all over the world are seeking to include functional traits in their breeding programmes (Groen et al. (1997), Christensen et al. (1998)). A great amount of research is done on potential index traits for indirect selection for health traits (Groen et al. (1997)). The whole constitution of the animals is to some extent considered in Scandinavian breeding programmes using the epidemiological data of all herd book animals (Philipsson et al.

Provedor de dados: 21
Autores: Planner, Anna-Theresa; Koch, Robert; Degen, Barbara.
Schafwolle wird im Zierpflanzenanbau als organischer Dünger eingesetzt. Bei der Erzeugung von Frühjahrsblühern (Bellis perennis und Myosotis sylvatica) wurde die vollständige Bevorratungsdüngung mit Schafwollpellets in drei verschiedenen Größen und mit geschnittenem Schafwollvlies getestet. Mit einer Düngungshöhe von 6-10 kg Schafwolle/m³  bei B. perennis und 10 kg/m³ bei M. sylvatica konnten gute Pflanzenqualitäten erzielt werden. Düngung mit kleinen Pellets führte zum höchsten Nmin-Gehalt im Substrat und zum besten Pflanzenwachstum, welches durch die Messung von Frischmasse, Höhe und Durchmesser der Pflanzen ermittelt wurde. Pflanzengesundheit und Gesamteindruck wurden bei Düngung mit geschnittenem Schafwollvlies am besten bewertet.

Die gesellschaftlichen Kosten der Landwirtschaft sind von großer Bedeutung. Können diese gesellschaftlichen Kosten näher ökonomisch bestimmt werden? Inwiefern unterscheidet sich der Ökolandbau von der konventionellen Landwirtschaft in dieser Hinsicht? Im Rahmen einer Literaturanalyse wurden sieben Bereiche gesellschaftlicher Leistungen in Bezug auf diese Fragen analysiert. Die Analyse ergab, dass die gesellschaftlichen Kosten sehr hoch sind, aber dass sie sich mit der bestehenden Literatur nicht genau abschätzen lassen. Desweiteren schnitt der Ökolandbau in den Studien, die einen ökonomischen Vergleich der gesellschaftlichen Leistungen von Ökolandbau und konventioneller Landwirtschaft durchgeführt haben, besser ab.

Autores: Vormann, M.; von Borstel, U.; Leisen, E.
In order to produce high quality forages, the species composition of the grass sward is of special importance. A good measure for estimating the quality of grass swards is  the so-called mean Futterwertzahl of the sward by Klapp (1965) which is further referred to as Sward Quality Index (SQI). On 56 organic farms the average SQI of the farm has been calculated and the yield proportion of different species of the sward has been calculated for different regions of Northwest Germany. Within 22 organic farms  with grassland farming exclusively, a comparison of the milk yields (kg ECM/cow and year) and the mean SQI of the grassland has been calculated with special regard to  the concentrate rates fed to the cows. In tendency the results show lower SQI in farms...

Autores: Hirte, J.; Leifeld, J.; Oberholzer, H.-R.; Mayer, J.
Below ground carbon (BGC) inputs by agricultural plants into the soil are an important variable in soil carbon (C) modelling. The sources for BGC inputs are dead root biomass and C release by living roots (C rhizodeposition). Since management effects on BGC inputs are not profoundly understood, we address the following research questions in this research project: (i) What are the proportions of root biomass and C rhizodeposition of the total BGC input in the topsoil and subsoil under maize cultivation at different sites? (ii) Does long-term fertilization practice affect total root biomass, root distribution, shoot/root ratios, and C rhizodeposition of maize?

Autores: Pietsch, Gabriele; Hrbek, Regina; Schmutzer, Gerd; Friedel, Jürgen K.
We studied the effect of a mulching regime optimised with respect to nature conserva-tion on yield and nitrogen fixation rate of Lucerne. The first harvest was two weeks earlier and the second harvest was two weeks later than usual. At the first harvest in 2004, the shoot yield from the nature conservation variant was significantly lower than the yield from the usual treatment. At the second harvest date in 2004, there where no differences. The total nitrogen fixation in 2004 did not differ between the treatments. In 2005, both shoot yield and total nitrogen fixation showed no differences between the two variants as well. From this study it can be concluded that a displacement of mulching dates of Lucerne in most cases will have no significant effect on...

Beziehung von Blatt- und Fruchtbefall mit Braunfäule bei Freilandtomaten
Provedor de dados: 21
Autores: Butz, Andreas F.; Finckh, Maria R.
There is virtually no information available on the relationship between the reaction of tomatoes to Phytophthora infestans on leaves and fruits. Late blight and brown rot of tomatoes were assessed in outdoor conditions in 2005 on 15 tomato varieties and in 2006 for 41 varieties. Leaf disease expressed as area under the disease progress curve (AUDPC) and the proportion of healthy fruit of the total fruit were used as meas-ures. In 2005, the two varieties that were most susceptible to leaf blight produced the least healthy fruit while the most resistant variety produced the highest proportion of healthy fruit. However, for the varieties with more intermediate reactions to leaf blight there was great variation in the proportion of healthy fruit with an...

Beziehungen zwischen Rohprotein- und Aminosäuregehalten in ökologisch erzeugten Ackerbohnen (Vicia faba L.)
Provedor de dados: 21
Autores: Witten, Stephanie; Böhm, Herwart; Aulrich, Karen.
In der Fütterung monogastrischer Nutztiere spielt neben der ausreichenden Menge an Rohprotein (XP) auch die Proteinqualität eine entscheidende Rolle. Die Proteinqualität hängt maßgeblich vom Verhältnis der Aminosäuren (AS) untereinander ab. Ein negativer Einfluss steigender XP-Gehalte in verschiedenen Körnerleguminosen auf das AS-Muster ist bereits beschrieben worden (Schumacher et al. 2011, Wang et al. 2004). Da ein hoher XP-Gehalt ein wichtiges Kriterium bei der Sortenwahl ist, ist es von noch größerer Bedeutung, eine solche Abhängigkeit zu erkennen.  Ebenso wie in der Literatur beschrieben, nahm in dieser Stichprobe der Gehalt einiger essentieller AS tendenziell mit steigendem XP-Gehalt ab. Unter diesen befinden sich die in der Monogastrierfütterung...

Bi-cropping fodder maize in an existing (grass)clover sward
Provedor de dados: 21
Autores: Prins, U.; Eekeren, N. van; Oomen, G.J.M.
Organic cultivation of fodder maize is still considered to be difficult. Weed pressure, soil structure degradation during harvest and low nutrient efficiency are some of the common problems. Directly sowing maize in a (grass)clover sward using special-ized drilling machines can solve these problems. In a bi-cropping experiment under organic conditions we found similar yields as the reference treatment (ploughing) when the maize was sown in a clover sward, the roots of the remaining sward were cut one week after sowing and an additional fertiliser was applied.

Bicropping im ökologischen Winterweizenanbau - eine Alternative zum Anbausystem der „Weiten Reihe“?
Provedor de dados: 21
Autores: Neumann, Helge; Loges, Ralf; Taube, F.
Das "Weite Reihe"-System gilt als ein Verfahren zur ökologischen Produktion von Qualitätsweizen. Auf dem Versuchsgut für Ökologischen Landbau und extensive Landnutzungssysteme der Universität Kiel wurden in den Erntejahren 1999-2002 verschiedene Feldversuche zur Optimierung des Weite Reihe-Anbaus von Winterweizen durchgeführt (Variation von Reihenabstand, Weizensortentyp, Aussaatstärke, mechanischer Pflegeintensität, Untersaat). Im Anbaujahr 2001/02 kamen zusätzlich verschiedene Bicropping-Verfahren zum Einsatz, bei denen auf den Einsatz des Pfluges verzichtet wurde und die Weizenansaat direkt in einen Weißkleebestand erfolgte (verschiedene Techniken).  Die getesteten Weite Reihe-Systeme führten in allen vier Versuchsjahren zu Mindererträgen. Die weite...

Bicropping systems based on forage legumes undersown in winter cereals can  achieve yield and quality improvements with sufficient water supply during the main  growth phase, but fail under dry site conditions (continental climate, sandy soil). To  improve the N-supply without the risk of interspecific water and nutrient competition,  bicropping systems were developed with simultaneously or parallel intercropped nonhardy  grain legumes at in early sown winter cereals or oil seed rape. They were tested  in practice with on-farm experiments carried out in Brandenburg and Bavaria. Besides  a sufficient erosion protection, a significant N-input can be achieved with grain  legumes in autumn especially within rape and early sown winter cereals. But only  cereals...

Weed control in organic carrot production is time and cost intensive. There are several practicable techniques available for inter-row weed control, but the most sensitive area - ted by manual weeding. Weed regulation is usually done in uniform operations for one field, but weeds appear in a huge spatial variability, reflecting heterogeneous soil and climate conditions. Following the idea of precision farming, we developed a concept for camera-based weed detection, which displays the density as recommendation for  velocity adaptation for the driver. The system was tested against the usual weeding with one constant velocity in a field trial with randomized plots. By using the new  technology it was possible to increase the area performance by higher average...

Dem biologischen Landbau haftet das Image an, teure Produkte für eine begrenzte Käuferschicht zu produzieren. Allerdings definiert sich die biologische Landwirtschaft nicht als elitär, und trachtet nach fairen Beziehungen zwischen ProduzentInnen und KonsumentInnen.  Einen Beitrag zur Verständigung zwischen Produktion und Konsum leisten auch Initiativen einer „gemeinschaftlich getragenen Landwirtschaft“. Dabei werden Konsumentinnen und Konsumenten in unterschiedlicher Form an der Produktion beteiligt, sei es durch Gemüseabonnements oder durch die aktive Mitarbeit auf dem Feld. Allerdings hat sich gezeigt, dass auch diese Initiativen insbesondere eine gut gebildete und eher gut situierte Kundenschicht anziehen.   Die Frage ist, wie das Potential des...

Bio Suisse Bans Hybrid Cereals
Provedor de dados: 21
Autores: Arncken, Christine; Schmid, Otto.
On April 19th, 2006, the 100 delegates of Bio Suisse, the Swiss organic umbrella organization, voted to ban Hybrid varieties in organic cereals (except maize). This decision primarily concerns rye. Organic rye is grown on only 250 ha, about 20% of which is sown to hybrid varieties at present. About 60% of total organic demand is imported. Hybrid varieties of the other cereals are not yet being grown. The delegates decided that it is time to act now to send a signal to breeders and to the international organic community before the alternatives to hybrids vanish.

The accumulation of heavy metals in soils is a potential risk that may keep organic  farmers from using biowaste compost. As the ecological effects of metals are related  to mobile fractions rather than to total contents in the soil, we measured the total  (aqua regia extractable) heavy metal contents, the readily available water soluble and  the potentially bioavailable LiCl-extractable fraction of soil heavy metals in a field  experiment after ten years with total applications of 95, 175 and 255 t ha-1 biowaste  compost (fresh matter). Total soil contents of Cd, Cr, Cu, Ni and Pb in the compost  treatments were not significantly higher than in the unfertilized control.

Exotic potatoes other than S. tuberosum ssp. tuberosum cultivars may have a high  interest in terms of commercialization in Russia and in Europe. In Finland, on the  market there is already one potato cultivar called Blue Congo, which has a dark purple  skin also with a purple flesh. This clearly shows that potatoes even with considerably  irregular shape and completely exceptional flesh colour can have market potential.    Some potato species are known to have high protein content in tubers, which is also  important for need of production in developing countries.

Organic and low-input farming systems provide habitats for wildlife on farmland. The EU FP7 project BIOBIO has identified a core set of 23 indicators relating to the diversity of habitats, of species, of crops and of livestock. Management indicators capturing the pressure on biodiversity are also proposed.  The indicators were identified in an iterative process between scientists and stake-holders to make sure that they are not only scientifically sound but also practicable and attractive. They were tested in 12 case study regions on four major farm types. Allocating 0.25 % of the CAP budget to a farm scale biodiversity monitoring would allow to measure and analyse the indicators on 50,000 farms across Europe.

Provedor de dados: 21
Autores: Scheifele, Michael; Buegger, Franz; Fliessbach, Andreas; Mäder, Paul; Schulin, Rainer; Gattinger, Andreas.
Results  › Carbon mineralization rates were highest in maize straw and lowest in pyrochar amended soil.  › Pyrochar showed even lower CO2 fluxes than non-amended soil.  › Initial mineralization rates of maize straw and hydrochar were higher in soil M, whereas in Soil D the pyrochar was decomposed slightly faster.  › Hydrochar derived carbon was readily incorporated in the microbial biomass of both soils, pyrochar resisted nearly completely.  › Comparison of carbon pools CO2 , Cmic and Corg at day 12 and day 205 shows that a stabilsation of maize feedstock of more than a double could be achieved with HTC and far beyond that scale with pyrolysis.

One year after the conventional farm started the conversion process in 2002, a long term farming system monitoring was established in the Eastern region of Austria. The goal was to evaluate the performance of organic arable farming and its biotopes (flowering stripes, hedges and tree rows), and specifically their impact on biodiversity. After nine years organic farming we note a considerable increase of biodiversity in the arable fields and accompanying biotopes. Indicators applied were soil fauna, breeding birds as well as weeds. Space-time aspects, rotation and management measures as well as crop specific characteristics were influencing the development of species diversity. The development of diversity however is limited due to the intense farming in...

Biodiversität fördern und nutzen – Schädlingsbekämpfung im Kohlanbau
Provedor de dados: 21
Autores: Luka, Henryk.
In cabbage fields parasitoid wasps (Hymenoptera) use the eggs or larvae of pest butterflies and moths for their own reproduction, ultimately killing them. In this way these parasitoids play an important role in the biological plant protection strategy. An efficient way to promote this parasitoids in the crop field is to provide them with flower strips as well as companion plants, e.g. cornflower, that will provide them with food (nectar) and shelter. Between 2007 and 2010 we conducted experiments to test the olfactory attractiveness of different flowers as well as the influence of their nectar on the regulation of the cabbage moth (Mamestra brassicae) as well as on the lifespan and parasitation performance of its antagonists (egg and larval parasitoids).

Biodiversitätsbewertung in landwirtschaftlichen Ökobilanzen:  Eine Herausforderung
Provedor de dados: 21
Autores: Gabel, V.; Meier, Matthias Samuel; Stolze, Matthias; Köpke, Ulrich.
Within the last years the demand and use of Life Cycle Assessment (LCA) for calculating and comparing the ecological impacts of agricultural products has increased. In addition there is growing awareness that biodiversity impacts should be included in comprehensive LCAs. This has led to research efforts with the goal to develop and implement methods for biodiversity impact assessment. Especially for organic agriculture such a development is important because thus the often in literature described biodiversity differences between conventional and organic farming could be pictured. In a review, twenty-two different biodiversity impact assessment methods have been analyzed. Their suitability for the evaluation of agricultural  products was questioned....

This paper presents results of an on-farm biodiversity assessment of 45 organic arable farms in eastern Austria (region Weinviertel). The core of the assessment method consists of 99 parameters concerning agricultural practices and semi-natural habitats and their impacts on genetic diversity, habitat diversity and species diversity of eleven indicator species groups. For each farm, a biodiversity performance score was calculated ranging from 0 to 100 %, where 100 % would be reached with the highest possible scores for all parameters. The biodiversity assessment of the 45 organic arable farms revealed big between-farm differences in the biodiversity performance (16.8 to 50.6 %; Ø 32.8 ± 6.1 %). While 32 farms for example achieved biodiversity scores &gt; 40...

This presentation takes as its starting point the relationship between humans and global natural resources. Humans have always been dependent upon them. Only recently, however, has it become obvious that the demand for these natural resources and services is now approaching or exceeding their supply. Sustainability can be defined as using the natural resources we are dependent upon in the most efficient manner possible - also biodiversity.   Human activities have dramatically increased over the last approx. 60 years and these activities leave a fingerprint on many aspects of the Earth System. A large part of this fingerprint is the result of impacts caused by or related to agriculture.   The presentation presents a study in which an attempt is made to...

Biodiversity and economic incentives in agriculture : integrating bird fauna values into decision-making
Provedor de dados: 21
Autores: Miettinen, Antti; Huhtala, Anni.
Our optimal control model identifies economic reasons as to why several farmland bird populations have dramatically declined in modern agricultural landscapes. By integrating bird fauna values into decision-making on cereal crop choice, herbicide use and hunting bag size, we derive those economic instruments needed for enhancing biodiversity on farmland and reversing the decline of grey partridge (Perdix perdix) populations. Based on the Finnish data available, we illustrate how the optimal acreage subsidy for organically-grown rye areas, the herbicide tax rate and the grey partridge hunting licence fee could be estimated in monetary terms. The procedure to derive and value the first-best policy instruments is applicable for various components of...

This report was presented at the UK Organic Research 2002 Conference. The recent Curry Commission report recognised the need to provide incentives for the production of public goods in terms of the environment. This is a particular advantage for organic farming because its biodiversity benefit is no longer being seriously questioned and many, large NGOs have a positive policy attitude towards organic farming. However, to ensure a good deal for organic farming in any new development of agri-environment schemes, the organic sector needs to play a positive role, with careful consideration of all steps in the development of policy.

Autores: Simon, Sonja; Demmeler, Martin; Heißenhuber, Alois.
To satisfy national sustainability targets in Germany, both bioenergy and organic farming claim a growing area of farmland. Analyses with a land use model and ac-companying expert interviews show, how the competition for land is growing in certain regions. A restricted area potential for energy crops – even with an ever intensifying farming opposes targets for an increasing share of land for organic agriculture and nature conservation. Thus there is a need for policy action, to discuss and solve this goal conflict. An ongoing study currently develops strategies for two selected German regions for a more ecologically compatible bioenergy production.

Autores: Thomsen, MH; Tajoacha, N; Wu, C; Hovgaard, S; Houmøller, LP; Holm-Nielsen, JB; Thomsen, AB.
The most well-known way to produce bioethanol is by the enzymatic hydrolysis and fermentation of starch. In a new project “BioConcens” (2007) sponsored by DARCOF (DAnish Research Center for Organic Food and farming) one aim is to  develop a combined ethanol and biogas production for use in organic farming using starch containing biomass. Natural enzymes from cereals will be used for hydrolysis of starch to glucose in accordance with technology in brewing technology. Commercial enzymes are often produced from gene-modified organisms and will therefore not be used in the suggested organic context or process.

Bioethanol production from germinated grain by inherent  enzymes
Provedor de dados: 21
Autores: Kádár, Zsófia; Christensen, Anne Deen; Thomsen, Mette Hedegaard; Thomsen, Anne Belinda.
The malting in brewing process develops enzymes that are required to hydrolyze the complex starch in grain into simple fermentable sugars. These proceed the three following steps: Steeping encourages germination to start, germination prepares the conversion of the starch to sugars, and kilning stops the germination.  In this study, a method for bioethanol production from rye grain was developed by utilizing the inherent amylase activity from germination of the seed. Grain germination was performed in two steps (steeping, germination) under different conditions, where the effect of temperature, duration and humidity was examined on amylase activity and final ethanol yield. Commercial enzymes were used for reference experiments.  Simultaneous...

Autores: Seppänen, Mervi; Kontturi, Juha; Hartikainen, Helinä.
Selenium (Se) is an essential micronutrient for humans and animals which is circulated  to food chain via crop plants. Agronomic biofortification with Se is used in areas where  the soil Se content is low and Se deficiency causes health problems. Brassica species  are efficient in accumulation of soil Se and therefore an attractive choice of species for  biofortification. Se uptake and translocation was studied in B. rapa and B. napus in  field experiments applied with 0, 6 or 20 mg Se ha-1 as Na2SeO4 and foliar sprays of  30 mg Se ha-1 as Na2SeO4 or Na2SeO3. In addition, a HPLC-ICP-MS based method to  identify and quantify organic Se-compounds in seeds and meals was developed. High  concentration of Se accumulated in seeds (1.89 μg g-1) and after oil...

Organic agriculture is one sustainable alternative to avoid negative environmental effects often caused by conventional agriculture. The area for organic farming in Europe is increased rapidly in the last decades and Denmark is one of the top-ten countries in Europe as regards the organic share of the total cultivated area.  The production of bioenergy from local biological resources and the maintenance of soil fertility seem to have been opposing aims in organic agriculture. In organic farming, there is a strong effort to reduce the reliance on fossil fuels and decrease greenhouse gas emissions in organic agriculture.   Cheese whey is a by-product from the dairy industry, which has the highest market share of organic foods in Denmark. It generates...

Biofumigation - an alternative method to control late blight in organic potato production?
Provedor de dados: 21
Autores: Grabendorfer, Sebastian.
To control late blight in organic potato production currently copper fungicides are used. Due to problematic aspects of copper fungicides, it's necessary to develop alternative methods to control Phytophthora infestans. In this context also the use of cover crops and particularly the method biofumigation are discussed. Because there's barely literature about the effectiveness of biofumgiation in organic potato production, the method is evaluated with laboratory experiments and field trials. Brassicacea have the potential to inhibit in vitro the growth of P. infestans, but in an one year field experiment it wasn't possible to observe positive effects to late blight infestation and tuber yields.

Biofumigation auch gegen pflanzenparasitische Nematoden?
Provedor de dados: 21
Autores: Eder, Reinhard; Roth, Irma; Zinsstag, Christof; Koch, Walter.
Biofumigation refers to a biological method to reduce diseases, pests and weeds in  the soil which is suitable for organic production systems. Cruciferous plants with a  high level of Glucosinolates are grown for about two months in the field. To achieve  the biofumigation effect, the intercrop is mulched during full bloom and rapidly  incorporated into the soil. The Gluconisolates are converted during biological  degradation into volatile substances toxic for certain diseases or pests. Nematodes  are also sensitive to these substances and are reduced thereby. Besides using the  incorporation of fresh plant material, pellets made of dried cruciferous plants and sold  as fertilizer might be an alternative approach for nematode control. The pellets are...

Biofumigation im ökologischen Kartoffelanbau: Effekte auf Knollenertrag, Blattnekrosen und Unkrautwachstum
Provedor de dados: 21
Autores: Grabendorfer, Sebastian.
Biofumigation is discussed as a potential method of securing tuber yields in organic potato production. Brassicaceae with high contents of glucosinolates are cultivated as cover crops and incorporated into the soil to support the development of isothiocyanates. A pot experiment with soil from two biofumigation field trials was conducted to test biofumigation effects on potato tuber yields, potato leaf necrosis and weed growth. In the field trials different cover crops (Vicia sativa, Raphanus sativus and Brassica rapa) and a control without any cover crop were incorporated into the soil in autumn or spring. Before incorporation in spring soil of the field plots was taken to pots together with one potato tuber. Common cover crop effects could be observed,...

Biofumigation zur Bekämpfung von Verticillium dahliae
Provedor de dados: 21
Autores: Michel, Dr Vincent.
Cruciferous plants with high contents of glucosinolates can be used to control soilborne  diseases. During the degradation of such plants, the glucosinolates are  transformed into isothio- and thiocyanates. These molecules are volatile and toxic,  therefore, this method is called biofumigation. In this context, the efficacy of two brown  mustard (Brassica juncea) and one canola (Brassica napus) cultivars to reduce the  number of Verticillium dahliae microsclerotia was tested in pot trials. Verticillium  dahliae is the causal agent of verticillium wilt of a large number of important crops.  Microsclerotia are the surviving structures of V. dahliae in the soil. A strong decrease  of the number of microsclerotia was observed using the high...

Biogas and Organic Farming: Empirical evidence on   production structure and economics in Germany
Provedor de dados: 21
Autores: Anspach, Dipl.-Ing.agr. Victor; Möller, Prof. Dr. Detlev.
Biogas production has an increasing importance on organic farms in Germany. Biogas plants have the possibility to produce energy, soil fertility and positive returns on capital. Yet previously no studies on the structure, economic outcomes and internal benefits of biogas production on organic farms existed. Therefore in 2006 and 2007 an empirical study, designed as a census, has been carried out to investigate these questions. Based on the empirical study a simulation model was built to analyse the economic potential. The highest economic potential, particularly if organic food and energy production are to be accomplished, was found for biogas plants which are mainly residual-based and on a farm scale size. The construction of small but also low priced...

Auch wenn die Stromerzeugung durch anaerobe Vergärung während ihrer Pionierphase in Deutschland vorwiegend auf Ökobetrieben entwickelt wurde, expandierte die Biogasproduktion im Ökolandbau weit weniger stark als in der konventionellen Landwirtschaft. Neben vielerlei anderen Gründen scheint die schwierige wirtschaftliche Situation aufgrund spezieller Produktionsanforderungen die Hauptursache dafür zu sein. Daher analysiert dieser Beitrag die Rahmenbedingungen der ökologischen Biogasproduktion und seine monetären Auswirkungen auf die Produktionsökonomik.

Biogas in organic agriculture: Effects on yields, nutrient uptake and environmental parameters of the cropping system
Provedor de dados: 21
Autores: Möller, Kurt; Stinner, Walter; Leithold, Günter.
System effects of biogas fermentation in organic cropping systems with and without livestock (dairy farming) were investigated from 2002-2005. In both systems no differences in yields and nutrient uptake were detected in the legume crops. In the livestock-system non legume crops of the slurry system had no higher yields but a higher nitrogen uptake (6 %) than the stable manure system. Slurry-fermentation had no effect on yields and nitrogen uptake. The inclusion of crop residues in the fermentation system increased the nitrogen uptake about by 10 % and reduced the nitrate leaching potential by ca. 10 %. The inclusion of external substrates lead to a further increase in nitrogen yield of 10 %, but to no significant increase in dry matter yields....

Biogas in Organic Agriculture: Utopia, Dead-End or Role model? - A Synopsis
Provedor de dados: 21
Autores: Blumenstein, Benjamin; Siegmeier, Torsten; Möller, Detlev.
Present-day organic biogas production provokes controversy of its role between the poles of societal demands, principles of organic agriculture and economic constraints. By integrating multiple arguments on organic biogas in a meta-level, several future trends are identified. However, only one option seems reasonable, where anaerobic digestion on a confined scale, mainly based on residual substrate input, serves both energy and food security demands while enhancing the productivity of organic farming systems.

Biogas in stockless organic Farming:   Effects of Digestion of Clover/grass, Cover Crops and Crop Residues on Nitrogen Cycles and Crop Rotation Productivity
Provedor de dados: 21
Autores: Stinner, Walter; Möller, Dr. Kurt; Leithold, Prof. Dr. Günter.
A common practice in stockless organic farming systems is to leave the biomass from clover/grass-ley and crop residues in the field for their residual fertility effect. No farmyard manures for transfer of nutrients within the system are available. Clover/grass-ley biomass and crop residues represents an unexploited energy potential that could be harnessed by the digestion in biogas plants for production of methane, thus replacing ruminants by the biogas digester. In field trials by implementing a whole crop rotation comprehending six crops were carried out in 2002-2005 to evaluate whether the use of N could be improved by processing biomass described above in a biogas digester and using the effluents as a fertilizer, compared to general practice.  Results...

Biogas nutrient management in organic cropping - not only a nitrogen issue
Provedor de dados: 21
Autores: Gunnarsson, A.; Asp, H.
Nutrient imbalance, mainly due to low K and high Ca and/or Mg concentrations, was a plausible explanation for low growth response to digestate fertilisation by beetroot following harvested grass-clover biogas ley. To derive the full benefit of a transition to a biogas nutrient management (BG) system, extra nutrients except for N may need to be added, especially if digestate supply is divided between many crop positions in the rotation. This is probably of extra importance on sandy soils such as that used in this experiment.

Biogas on-farm: energy and material flow
Provedor de dados: 21
Autores: Schäfer, Winfried.
Objectives:   European countries are committed to reduce CO2 emission originating from fossil fuels. On-farm produced biogas may replace energy produced from fossil fuels and so contribute to achieve the target. Up to now only in Germany a greater number of on-farm biogas plants has been established. The data of these plants can be used to evaluate cost and benefit of on-farm biogas production in other European countries. This paper concerns the following questions: Which parameters of biogas plant construction and operation have an influence on profit and sustainability of biogas production on-farm?    Hypothesis:   A biogas plant integrated within a self-contained farm organism is economically more competitive and more sustainable than an industrial...

In organic farming systems without livestock some problems arise concerning the nitrogen management: On the one hand, there is a lack of transportable nitrogen fertilisers, on the other hand there is a potential for high losses with the usual management. The biological N2 fixation is decreased, when clover grass is mulched. If the biomass of intercrops and clover grass gets mineralised in autumn, it can be leached in winter.   In the trial referred to here, the impact of fermentation of biomass on some agricultural parameters like yield etc. are investigated within a crop-rotation of clover grass, potatoes, winter wheat, peas, winter wheat and summer wheat with undersown clover grass. Intercrops are sown after winter wheat and peas.   In the control...

Cover or catch crops have beneficial effects for soil, water, erosion, etc. If harvested, they also provide feedstock for biogas without competition for arable land. The latter also applies to clover grass ley or other residues on organic farms without ruminants and for manure. With an explorative approach, combining field experiments and data collection of practical implementation, we investigated achievable yields and identified recommendations for practical use. Gross energy yields of cover crops varied between 700 and 2000 m³ methane (CH4) ha-1 in Austria. The energy return on energy invested (EROI) ranges from 4 to 7, if biogas is upgraded and com¬pressed for biofuel use. Therefore, about 1000 m³ CH4 ha-1 are remaining as net energy yield from 4.5 t...

In 2004/05, a field experiment regarding the effect of crop rotations for biogas-production to yield and soil properties was established at the organic experimental station Viehhausen. The different aspect of energy and food production and soil protection of the 5 main crop rotations are explained. The wheat yield 2007-09 was affected by legume percentage in crop rotation, which means partly lower yields but higher protein. The biogas slurry manuring increases the protein content in general but better in rotations with legumes.

Glucosinolates are amino acid derived allelochemicals characteristic of plants of the order Capparales. These compounds are present in seeds of agriculturally common Brassica crops in varying quantities depending on the species (ref). The use of the remaining seed cake after oil extraction has traditionally been limited by the concentration of these compounds. However, the extraction of glucosinolates from seed meal is nowadays possible and it further contributes to an increased quality of the seed meal for feed (Sørensen et al., this conference). Glucosinolates are hydrolysed by endogenous enzymes (myrosinases; EC 3.2.1.147) and a number of compounds are produced depending on the parent glucosinolate and the environmental conditions.1 Among these...

The biological control of plant diseases by application of antagonistic microorganisms to  the plant phyllosphere is an alternative strategy to prevent the frequent treatment of plants  by pesticides. Microbiological antagonists can firstly interact directly against the pathogen  by releasing antimicrobial compounds and/or secondly induce the plant resistance of the  host plant by expression of pathogenesis-related proteins (PR proteins). The focus of our  study is on the interaction of the non-pathogenic bacterium Pseudomonas fluorescens Bk3  to the plant phyllosphere of Malus domestica cv. Holsteiner Cox. After application of P.  fluorescens Bk3 to the phyllosphere of M. domestica cv. Holsteiner Cox we observed  dramatic changes in the protein...

Biological control of kiwifruit and tomato bacterial pathogens
Provedor de dados: 21
Autores: Balestra, Dr Giorgio M.; Rossetti, Dr Antonio; Quattrucci, Dr Alessio.
Biocontrol of bacterial pathogens is effected by using cupric salts associate to appropriate agronomical practices such as seed certification, irrigation and fertilization.  In in vitro and in in vivo tests, aqueous extracts from Allium sativum and Ficus carica fruits reduce the survival and the damages (disease incidence and disease severity) caused by bacterial pathogens of kiwifruit (Pseudomonas syringae pv. syringae, Pseudomonas viridiflava) and of tomato (Pseudomonas syringae pv. tomato) plants. In vitro tests, both vegetal extracts show antimicrobial activity against all bacterial strains utilised at different concentrations (106 – 108 cfu ml-1). In vivo tests Allium sativum and Ficus carica extracts confirm their antimicrobial activity on P. s. pv....

Biological control of the cherry fruit fly, Rhagoletis cerasi L. (Diptera, Tephritidae)  by use of entomopathogenic nematodes: first experiences towards practical  implementation.
Provedor de dados: 21
Autores: Herz, Annette; Köppler, Kirsten; Vogt, Heidrun; Elias, Ellen; Peters, Arne; Katz, Peter.
The use of entomopathogenic nematodes (EPN) is a promising approach to control the cherry fruit  fly, Rhagoletis cerasi L.. We already demonstrated the high potential of EPN to infect larvae after  leaving the cherry for pupation in the soil in laboratory and field experiments. For practice, an application  technique is needed, that is both, grower- and EPN friendly. We tested a tractor mounted  spray boom for treatment under the canopy area. The achieved rate of EPN in the soil met the expectations.  The activity of EPN in soil samples was high after application, but dropped to 60% of the  initial activity within one week. Exact forecasting of larval drop from cherries is another major challenge.  To obtain basic data, we recorded the phenology of...

Autores: Hetebrügge, K.; Fieger-Metag, N.; Kienzle, J.; Bathon, H.; Zebitz, C.P.W.; Zimmer, J.
The release of Aphelinus mali HALD. from artificial rearing for the control of Woolly Apple Aphid (Eriosoma  lanigerum HAUSM.) was tested in field trials. The release of adults proved to be more suitable than the release  of cards with parasitized mummies as practised in the first trial. Setting free adult A. mali at the beginning of  June reduced the aphid population, though its efficiency was not high enough to prevent damage of the trees  totally. The practical applications of A. mali in early spring (after blossom) were not effective because climatic  conditions were not suitable enough. The fertility of A. mali depends on temperature and light intensity.  The application of Micula (rape oil) and T-S forte reduced the growth of the aphid population...

To identify the effective characters and their relative importance in improvement of BNF, two separate field experiments were conducted under irrigated and rain-fed organic managements of dry, Pannonian region of east Austria. The experiments were laid out in an α-lattice design with two replications and 18 genotypes (eight Iranian ecotypes and ten European cultivars). Plant height was positively and significantly correlated with leaf area index (LAI) and shoot dry matter (DM) under both conditions. Positive correlations were found between biological nitrogen fixation (BNF) and shoot DM (r = 0.61** and 0.87**, irrigated and rain-fed management, respectively). Regarding correlation coefficients, high yielding genotypes had taller plants and denser stands,...

Biological soil quality as a factor of efficient resource utilization in organic farming systems
Provedor de dados: 21
Autores: Fliessbach, A.; Mäder, P.
In 1978 the DOK long-term field experiment was installed at Therwil close to Basel comparing the farming systems „bio-Dynamic“, „bio-Organic“ and „(K)conventional“. In the first years of the trial, crop yield and feasibility of organic farming were investigated. Soils were analysed with respect to long-term effects on fertility and were evaluated in the view of farming effects on the environment. Today the interrelation of diversity and efficiency and the quality of organic products is the research focus. Long-term trials like the DOK-trial offer unique opportunities for this kind of research.  The DOK-trial compares the three systems mentioned above on the basis of the same intensity of organic fertilization (i.e. the same number of animals per area), the...

The aim of this study was to investigate the effect of way of tomatoes cultivation on content of both health promoting and toxic components representing by carotenoids (lycopene, β-carotene), vitamin C and glycoalkaloids (α-tomatine, dehydrotomatine). The levels of biologically active compounds were shown to be strongly affected by the degree of maturity of fruit and varied among system with various fertilizers. Slurry, organic fertilizer with high fertilization efficiency, is good alternative to mineral fertilization. Lower content of toxic glycoalkaloids was found in tomatoes from organic and combined “low input” farming. The differences were variety depended in some extent.

We investigated the virulence of three European isolates of the entomopathogenic fungus (EPF) Metarhizium anisopliae against three wireworm species which are important pests of arable crops and vegetables in Europe: Agriotes lineatus, A. obscurus and A. sputator. In laboratory experiments, up to 90 % of the wireworms were killed by the fungus, depending on the fungal isolate and the wireworm species. Speed of kill was generally low with first wireworms showing unambiguous signs of fungal disease after two to three weeks. Maximum mortality rates were reached after six to eight weeks post inoculation. The next steps of this investigation will be to determine the most suitable fungal isolate and the validation of the laboratory results under greenhouse and...

The greatly increased market share of organic food, has prompted increasing interest in investigating whether there are actual differences in the effects of organic and conventional food on health. Previous studies have focussed on composition analyses and have therefore not been able to provide definitive proof for differences between these two food production systems in terms of long-term impact on human health. Also the designs of some of these studies were inadequate to provide proof for definite composition differences. There are virtually no human dietary intervention and cohort studies, which can provide definite proof for potential health impacts.

Plasmopara viticola, the causai agent of grapevine downy mildew is very well adapted to its host pianI. Therefore it is very difficult to develop methods for the biological control which meet the requests of ecological viticulture. One of the possibilities for a biological control of grapevine downy mildew is the usage of the natural resistance potential of the European cultivars of Vitis vinifera, more exactly the induced resistance. Another way is the use of specific inhibitors which either stop the infection process or have an effect on the interaction of the pathogen with the host pianI. Whereas generai information about the resistance reactions in plants is available and the first results were also won for vine, the knowledge about inhibitors is very...

Farmers networks are a valuable instrument for research, development and innovation in organic agriculture. The last 15 years networks of pilot farms have been used in the Netherlands to improve farm performance for integrated and organic farming.  For organic agriculture the BIOM network was set up in 1998. Participating farmers improved their farm performance amongst others by a decrease of the hand labour for weed control and a reduction of the nutrient surpluses. The network also functioned as a facility for on-farm research on various topics. Additional effects of the close contacts between par-ticipants were a closer cooperation between farmers and an incentive for innovation

Energy production and energy use in organic agriculture (OA) need to be addressed in order to reduce the reliance on non-renewable fossil fuels and minimize greenhouse gas (GHG) emissions. Thus, there is an obligation to find consensus between the apparent opposing aims of renewable (bio) energy production and soil fertility in OA. This project aims at designing and evaluate a combined concept for biomass and bio-energy production in OA, while considering soil fertility.

Zusätzlich wurde der Alkaloidgehalt der Lupinen ermittelt, da dieser einen Einsatz der Biomasse in der Tierernährung verhindern kann. Die Ergebnisse zeigten Bioamsseerträge vo 3,6 bis 3,9 t Trockenmasse pro Hektar und Lupinenanteile von ca. 30% im Mittel. Der Alkaloidgehalt in den Lupinen wies eine Spannweite zwischen 0,7 und 2,5% in der Trockenmasse auf und war signifikant abhängig vom...

Biomonitoring der weiträumigen Verdriftung von Pestiziden mittels Baumrinde, Vegetation und Passivsammler
Provedor de dados: 21
Autores: Hofmann, Frieder; Kohlschütter, Niels; Bär, Johanna; Vögel, Rudolf; Kruse-Plaß, Maren.
Anlass für ein Biomonitoring zur weiträumigen Verfrachtung von Pestiziden über die Luft war die wiederholte und erhebliche Kontamination von Bio-Körnerfenchel mit zugelassenen, häufig applizierten Pflanzenschutzmitteln, die kilometerweit von den Fenchelflächen angewendet wurden. Zudem wurde für Glyphosat eine breite Belastung der Bevölkerung gemessen: 99,6% von über 2000 Probanden der bundesweiten Studie „Urinale 2015“.

Bio-PhytoPRE - ein Warn- und Prognosesystem zur Bekämpfung der Kraut und Knollenfäule im ökologischen Kartoffelanbau in der Schweiz
Provedor de dados: 21
Autores: Musa-Steenblock, Tomke; Forrer, Hans-Rudolf.
In organic potato production, copper fungicides are the only mean for an effective direct control of late blight. To avoid negative impacts of copper accumulation in the environment, intensive research is done to develop efficient copper free agents (CFA) and new strategies for disease prevention. However, the search for such CFA and strategies proves to be more difficult than expected. Therefore an abdication of copper products is not yet possible. To approach a copper free organic potato production, the Agroscope FAL Reckenholz is developing the Bio-PhytoPRE decision support system to assist Swiss organic potato producers to control late blight with reduced amounts of copper or CFA.

Biopore characterization with in situ endoscopy: Influence of earthworms on carbon and nitrogen contents
Provedor de dados: 21
Autores: Athmann, Miriam; Kautz, Timo; Huang, Ning; Köpke, Ulrich.
Biopores have been shown to be enriched with plant available nutrients as compared to the surrounding bulk soil and therefore are considered hot spots for the nutrient acquisition especially in the otherwise nutrient-poor subsoil. However, depending on their individual biography, i.e. colonization by plant roots or earthworms, different nutrient status can be assumed. In this study, individual biopores were characterized with respect to signs of earthworm passage using in situ endoscopy, a non-destructive technique for display of pore wall characteristics. Subsequent sampling and analysis of biopore linings and blockages revealed that only biopores with visible earthworm coatings had significantly higher C and N contents as compared to the surrounding bulk...

Bioporen: Ihre Bedeutung für das Wachstum der landwirtschaftlichen Kulturpflanzen
Provedor de dados: 21
Autores: Kautz, Timo; Athmann, Miriam; Köpke, Ulrich.
The subsoil (i.e. the soil beneath the ploughed soil layer) provides a large potential reservoir of nutrients for crops but the conditions for nutrient acquisition are generally adverse due tolow organic matter contents, low nutrient concentration in the soil solution, low microbial activity and high bulk density. However, the structural heterogeneity of the subsoil including biopores created by roots and earthworms requires a more detailed view on nutrient acquisition processes. First results from the DFG research unit ‘Crop Sequence and the Nutrient Acquisition from the Subsoil’ have shown that cultivation of perennial fodder crops with taproot systems can result in enhanced biopore density in the subsoil and increased root-length density of subsequent...

Biorefinery concept in organic agriculture: combined  bioethanol and biogas production
Provedor de dados: 21
Autores: Kádár, Zsófia; Oleskowicz-Popiel, Piotr; Schmidt, Jens Ejbye; Thomsen, Anne Belinda.
Organic agriculture is one sustainable alternative to avoid the negative environmental effects often caused by conventional agriculture. BioConcens is an interdisciplinary project aims at developing new biorefinery concept and processes for co-production of bioethanol, biogas and animal feed based on resources from organic agriculture (clover grass, straw) and associated food processing (whey). Bioenergy produced in organic agriculture can reduce its dependency of fossil fuels and decrease greenhouse-gas emission, and at the same time it is important that carbon and nutrients cycle are not influenced negatively. Biogas can be produced from any carbon rich waste/by-product, which can be further utilized in combined heat and power plant to produce heat and...

Biorefining of proteins from grass clover as an innovative solution to a truly sustainable organic production
Provedor de dados: 21
Autores: Fog, Erik; Ytting, Nanna Karkov; Lübeck, Mette.
To shape a common solution to challenges with low crop yields, proper protein supply and insufficient climate mitigation capacity, biorefining of protein feed from grassland crops for monogastric animals (including human) is introduced to the organic production system. Bio-refining using mechanical and natural fermentation techniques are compatible with the organic principles and standards. Crop yields from Danish field trials with alfalfa, clover and grass-clover mixtures demonstrate average yields around 12 tons dry matter per hectare yielding on average 700 kg extracted protein per hectare and 3000 to 6000 m3 methane per hectare. With these yields the profitability of biorefining of organic protein feed is calculated and shows a positive economic...

Biosafety data improving the regulation of Co-existence
Provedor de dados: 21
Autores: Boelt, B.
Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards. Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds. Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence.

In this paper we study the current prioritisation of poultry diseases in Finland using clustering to classify diseases based on their risk management profiles. On basis of the  clustering, three cluster types could be found: 1) Risk-based clusters, where the level of risk seems to be a common factor within the clusters; 2) Consequence-based  clusters, which have grave consequences and long history of risk management, but unclear probability; and 3) Unclear clusters, which show a wide variability in  probability and impacts within the clusters.

Provedor de dados: 21
Autores: Elmholt, Susanne; Munkholm, Lars J.; Debosz, Kasia; Schjønning, Per.
During the last decades Denmark has experienced a growing interest in low-input farming systems like organic farming. These systems rely on a high soil fertility to maintain nutrient availability and plant health. Soil aggregation contributes to this fertility, because it is crucial to soil porosity, aeration and infiltration of water. This paper reports a study of two pairs of differently managed, neighboring fields. The aim was to elucidate long-term effects of the different farming systems on physical and biological variables with influence on bonding and binding mechanisms of soil aggregation. Each pair consists of an organically grown dairy farm soil, based on a forage crop rotation system, including grass (Org-FCS(G)) and a conventionally managed...

Mittlerweile leben und ernähren sich fast 800.000 Menschen in der Bundesrepublik vegan. Doch ein veganes Lebensmittel auf dem Teller entsteht selten entlang einer durchweg veganen Produktionskette. Hier setzt die bio-vegane Landwirtschaft an, welche sich vom viehlosen Ackerbau abgrenzt. Bio-vegane Landwirte verzichten bewusst auf tierischer Bestandteile und Betriebsmittel. Merkmale sind Gründüngung, der Anbau von Zwischenfrüchten, eine weite Fruchtfolge sowie der vorbeugende Pflanzenschutz. Herausforderungen sehen die befragten Praktiker_innen in den Bereichen Pflanzenernährung, Beikrautdruck, Schädlinge und Krankheiten, Bodenstruktur sowie Ökonomie. Die Ergebnisse zeigen auch, dass Forschungs- und Beratungsbedarf besteht.

Bio-Weidehaltung bei Verwendung von automatischen Melksystemen (AMS) - Ergebnisse von Praxisbetrieben in Österreich
Provedor de dados: 21
Autores: Steinwidder, Andreas; Sturm, Michaela.
Die Kombination von Weidehaltung mit automatischen Melksystemen (AMS) stellt besondere Herausforderungen an das Betriebs-, Fütterungs- und Weidemanagement. In der vorliegenden Arbeit wurden Ergebnisse und Erfahrungen von 10 österreichischen Bio-AMSWeidebetrieben erfasst. Der Kuhbestand der Betriebe war mit 36 Kühen gering, die AMS-Auslastung lag im Mittel bei nur 44 % (26 bis 60 %). Die Betriebe stockten den Kuhbestand nach Umstellung auf AMS auf und reduzierten das Weideangebot leicht (-12 %), jedoch wurden hier große Streuungen festgestellt (-50 bis + 60 %). Bei der Entscheidung auf das AMS umzustellen waren arbeitswirtschaftliche Überlegungen wichtiger als ökonomische Gesichtspunkte. Die Melkfrequenz lag mit 2,4 Melkungen pro Kuh und Tag während der...

Black spot diseases in carrot
Provedor de dados: 21
Autores: Voorrips, Roeland E.; Zijlstra, Sierd; Köhl, Jürgen; Kastelein, Pieter.
An important problem in organic carrot production in the Netherlands is the occurrence of black spots during storage. Several different fungal pathogens cause similar symptoms, which are collectively known as black spot diseases. We identified Alternaria radicina, A. dauci and Rhexocercosporidium carotae (syn. Acrothecium carotae) as the most prevalent black spot pathogens. We developed laboratory test methods for resistance to A. radicina and R. carotae, and assessed resistance in a collection of cultivated varieties and more exotic material.

Black vine weevil and other wingless weevils: are there any effective conrol methods applicable in outdoor strawberry in Nordic countries?
Provedor de dados: 21
Autores: Lindqvist, Isa; Tuovinen, Tuomo.
The black vine weevil (Otiorhynchus sulcatus) is a common pest in Central Europe but rather new on outdoor crops in Finland. Spreading of enthomopathogenic nematodes against weevils by drip irrigation was tested at MTT during 2003-2004. The results proved that at least in small-scale use the nematodes were easily spread through the irrigation system into the field. We were not able to prove the efficiency of the nematodes against larvae because of too low level of both species populations in the experimental cages in the field.

Blattlaus- und Erbsenwicklerbefall in Wintererbsen-Reinsaaten: Ein Vergleich zu Sommererbsen-Reinsaaten und Wintererbsen-Mischsaaten
Provedor de dados: 21
Autores: Gronle, Annkathrin; Böhm, Herwart.
The infestation of peas by aphids and moths was assessed in winter pea sole crops and compared to spring pea sole and winter pea-triticale intercrops. The field experiments were conducted in Northern Germany in the growing seasons 2009-2011. The maximum number of pea aphids per plant and the percentage of attacked plants were lower in semi-leafless and normal-leafed winter pea sole crops than in semi-leafless spring peas. Pea moth larvae damaged 6-32 % of seeds in winter peas and 40-55 % of seeds in spring peas. Winter pea-triticale intercropping reduced the attack of pea aphids, whereas no beneficial effect of intercropping was observed concerning moth-damaged peas. Owing to the earlier maturity, winter peas were less susceptible to pea pest attacks than...

Autores: Hoischen-Taubner, Susanne; Sommer, Hendrik; Sundrum, Albert.
The nutrient supply of pigs and poultry in organic livestock farming suffers from a shortage of suitable home-grown protein sources. While clover-like legumes are widely used in cattle, the high levels of crude fiber restrict the use of these feedstuffs in the diet of monogastric animals. In the current study, comprehensive analyses were conducted with the focus on the leaf mass of clover-like legumes. The results revealed that in general leaf mass contained less fiber than the whole plant and on average high levels of protein and essential amino acids. However, values were severely affected among others by plant species, cut and time of harvest and thus varied considerably. Quality checks by analysis are required to make the potential of cloverlike...

Blue lupin as an alternative protein supplement for dairy cows fed grass silage-based diets
Provedor de dados: 21
Autores: Puhakka, L; Kokkonen, S; Jaakkola, S; Kokkonen, T; Vanhatalo, A.
We examined the effects of substituting rapeseed meal with blue lupin (Lupinus angustifolius) on production and metabolism of cows fed grass silage-based diets. The results show that dry matter (DM) intake and milk production increase when cereal grain is substituted with blue lupin (BL) but decrease when rapeseed meal (RSM) is replaced with BL. Owing to its high energy and protein content BL is a potential home-grown feed for supplementing forage-based dairy cow diets.

Provedor de dados: 21
Autores: Kramer, E.; Schiller, S.; Schulz, M.
One obstacle for the access of micro sized food enterprises to trading chains is the lack of IT based real-time specifications for produce, and to-date availability of information about management. To resolve this, a research project has established to develop an user-optimised, cloud-based enterprice resource planning (ERP) system that is tailored to suit the needs of such small enterprises. New functions such as reporting systems for food management and sustainability certification reports will be integrated. As a first result, an analysis showed that approx. 11 per cent of process based criteria of IFS and BRC certification can be mapped with to-date ERP systems, accentuating the need for this development.

Boar taint in very small organic entire male pigs - preliminary results
Provedor de dados: 21
Autores: Claudi-Magnussen, C.; Kongsted, A.G.
Very small entire male pigs can be part of a new concept of organic seasonal production of pigs. The concept includes outdoor production of small entire male pigs, very large female pigs and sows slaughtered after first litter. The entire males and the sows are slaughtered in the summer and the female pigs gilts in December. The purpose of the very small entire male pigs is to avoid castration and boar taint at the same time. In order to make the concept special regarding product quality and image, different crossbreeds are considered including a traditional Danish breed. Two seasons (2007 and 2008) are planned. Results of the 2007 season are presented.

Body Condition Scoring (BCS) zur Kontrolle von Fütterungsfehlern bei Milchkühen im Biolandbau im Hinblick auf Risiken für die Eutergesundheit
Provedor de dados: 21
Autores: Klocke, Peter; Dollinger, Julia; Ivemeyer, Silvia; Heil, Fritz.
Body Condition Scoring (BCS) is a simple method to control the energy supply of single dairy cows as well as for the entire herd. This is very important especially for organic herds due to limited resources of energy intake. Within an udder health pro-gramme regular BCS using a 5 point scale with 0.25 pt. steps is a good tool to detect feeding problems. The impact of fattened cows during dry time and meagre cows during lactation peak on metabolic health and fertility is known, but not the correlation between BCS and udder health. Within the extension programme “pro-Q” 530 dairy cows were scored at minimum twice during one lactation. The first time was 10 days before to 5 days after calving (BCS-1), the second time was in lactation up to day 100 (once or...

Boldness in fishes: A selection tool for aquaculture or a personality type with no apparent return?
Provedor de dados: 21
Autores: Skov, Peter V.
Behavioural and physiological results demonstrated that different emergence fractions of rainbow trout fry differed in certain characteristics. Early emerging fractions were more bold, they displayed more exploratory behaviour and recovered faster from startling compared to intermediate and late emerging fish. There were no differences in metabolic parameters of different emergence fractions, however, early emerging fractions had a smaller oxygen debt following chasing, and repaid it quicker. Early emerging fractions had a smaller cortisol response following a low water level challenge, but mobilization of glycogen stores did not differ between fractions. Early emerging fractions had a higher rate of weight loss in the face of starvation, probably linked...

Bombus terrestris as an entomovector for suppressing Botrytis cinerea in open field strawberry
Provedor de dados: 21
Autores: Mänd, Marika; Karise, Reet; Muljar, Riin.
Strawberry (Fragaria x ananassa) is a fruit crop grown worldwide, but diseases such as the grey mould Botrytis cinerea frequently limit its yield. Most of grey mould infection on the fruits is initiated during the flowering period. Use of foraging bees as disseminators of microbial control agents (MCAs) to flowers is known as entomovector technology. Many researchers have shown that bumble bees can efficiently vector MCAs; however, most studies have been conducted in greenhouse conditions.

Brassica cover crops for weed control in organic vegetable production
Provedor de dados: 21
Autores: Kristiansen, P.; Sindel, B.M.; Jessop, R.; Cerrai, D.
Cover crops (or green manures) are commonly used by organic vegetable growers for soil fertility building and other benefits including weed control. Brassica crops have been reported to control weeds in subsequent crops, usually attributed to the allelopathic effects of glucosinolates (GSL) in the brassica residues, although the effects are inconsistent. New brassica varieties with high GSL levels (Brassica juncea cv. Fumus and Raphanus sativus cv. Weedcheck) were tested in combination with mechanical weed control and another locally grown forage crop (Lolium multiflorum cv. Conquest) for their effects on weed growth during the pre-crop phase and subsequent weed and lettuce growth during the in-crop phase. The cover crops and bare fallow controlled weeds...

Brassica spp cover crop affects soil microbial activity, carbon and nitrogen nutrient dynamics
Provedor de dados: 21
Autores: Marinari, S.; Papp, R.; Marabottini, R.; Moscatelli, M.C.
A general positive effect of Brassica on soil microbial biomass and its activity was observed at all European sites in no tilled soil at both sampling date. Conversely, Brassica under tillage may produce a negative effect on biochemical properties after CC suppression. The effect of Brassica on C and N dynamics differed among the european sites when soil was tilled. These preliminary results establish the bases for the evaluation of the interaction between the pedoclimatic conditions and Brassica spp effect on soil properties.

Brassicas in sustainable production and organic farming
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian.
Brassica plant species show some characteristics in their use of plant nutrients which make them different from most other crops. These characteristics often make brassicas difficult to grow in low-input systems with limited nutrient availability, but at the same time they also make some brassica species valuable tools for reducing nitrate leaching losses and improving N management in farming systems. The paper presents experimental results on brassica crops as main crops and cover crops.

Extract from attached abstract:  ... results from the present study do not justify general utilization of HF sires from NZL to improve productivity and functional traits in grassland systems in Germany. Heterogeneous results were found with e.g. advantages for NZL_HF regarding health composites of feet and legs, but in contrast impaired udder health. The broad pool of German Holstein sires should be used to select specific sires for distinct environments and breeding goals, e.g. HF_DEU_P for grassland systems. Furthermore, the present study revealed genetic background for traits that are generally related to cattle husbandry and farm management, e.g. the welfare indicator THS.

Breeding and Production of Organic seeds, The Rijk Zwaan view
Provedor de dados: 21
Autores: Driessen, Ir. Ronald G.
Rijk Zwaan Seed Company offers organic vegetable seeds to the market. Breeding of varieties especially for the organic market has started, but only on a basic level. More knowledge and a more important market are needed to justify a higher input. In organic seed production many problems are encountered, espe-cially in seed production of biennial crops. Therefore much effort is put on improving the organic seed production of these crops, in cooperation with other companies, universities and institutes. Advanced seed treatments are needed to avoid seed borne pathogens. For further growth of the market for organic vegetable seeds, more knowledge, commit-ment in the whole organic chain and unambiguous regulations are needed.

Breeding apples with durable disease resistance
Provedor de dados: 21
Autores: Kellerhals, Markus; Kesper, Cornelia; Koller, Bernhard; Gessle, Cesare.
Apple cultivars with high fruit quality, good productivity and durable disease and pest resistance are highly required in ecological Fruit growing. In the past apple breeders mainly used single resistance genes giving good field resistance towards scab and mildew. They originate from wild species such as Malus floribunda 821, M. zumi and M. robusta. However, this type of resistance can be overcome by new pathogen races. Today the main emphasis is on the combination of functional different major resistance genes and the use of quantitative resistance to achieve durability. Molecular markers were developed which particularly permit the detection of major resistance genes. The combined presence of the target resistance genes in a seedling can be determined by...

Common bunt (Tilletia caries) is one of the most evastating plant diseases, and a particular problem for organic seed production. Organic farming aims at controlling pests and diseases with the use of biodiversity and resistance. However most organic wheat fields today are sown with monocultures of pure line varieties, and resistance to common bunt is rarely used, even this disease causes severe problems for seed producers and for farm saved seed, as infected seed lots are discarded because of contamination with bunt spores. To improve the system, organic wheat needs resistance to common bunt that is effective enough to prevent development of the disease over time.

Breeding for improved responsiveness to arbuscular mycorrhizal fungi in onion
Provedor de dados: 21
Autores: Galvan, Guillermo A.; Burger, Karin; Kuyper, Thom W.; Kik, Chris; Scholten, Olga E.
Arbuscular mycorrhizal fungi (AMF) play an important role in the uptake of nutrients and water from soil. Onions, Allium cepa L., are plants with a shallow root system. As a result, onion plants need a lot of fertiziler for their growth. Furthermore, onion plants are sensitive to drought. The aim of the current research project is to study the beneficial effect of mycorrhizal fungi on the growth and development of Allium species and to determine whether it is possible to improve onions for mycorrhizal responsiveness by means of breeding. Variation among Allium species and segregation observed in a interspecific tri-hybrid population indicate that selection and thus breeding for high responsiveness to AMF is possible.

Breeding for microbiome-mediated disease resistance
Provedor de dados: 21
Autores: Hohmann, Pierre; Wille, Lukas; Studer, Bruno; Bodenhausen, Natacha; Messmer, Monika.
Plant-associated microbial communities play a crucial role for the expression of various plant traits including disease resistance. Increasing evidence suggests that host genotype influences the composition and function of certain microbial key groups, which, in turn, effects how the plant reacts to environmental stresses. Several studies indicate that modern plant breeding may have selected against plant traits essential for hosting and supporting beneficial microbes. However, they also highlight the presence of an exploitable genetic base for the regulation of the rhizosphere microbiota.  We illustrate the concept of breeding for microbial symbioses with pea (Pisum sativum L.). Firstly, genotypic variation for the efficiency of a mycorrhizal symbiosis is...

Breeding for Mixed Cropping and Anthracnose Resistance of Lupins
Provedor de dados: 21
Autores: Arncken, Christine; Hohmann, Pierre; Messmer, Monika.
Introduction  In Switzerland, the organic sector has been trying to reduce the massive import of protein crops for feed by encouraging grain legume cultivation during the past years (Clerc et al, 2015). The main limiting factors of low yield stability and high weed pressure were successfully overcome through intercropping of peas and faba beans with barley and oats, respectively. Thus, the production of peas and faba beans grew continuously from 2010 to 2015 from 200t and 90t to 1170t and 560t, respectively (bioaktuell 2017). For more diversification of domestic grain legume cultivation and supply, FiBL has started field trials with blue (Lupinus angustifolius) and white lupins (L. albus) in 2014. The high risk of anthracnose, caused by the fungal agent...

Improving crop nitrogen use efficiency (NUE) is important to reducing the environmental impacts of agriculture, for both perennial and annual crops. This study tested winter wheat breeding lines developed in organic and conventional systems, historic wheat varieties and perennial wheat under organic management.  There were significant differences among selection categories and among genotypes. However, standard methods of measuring NUE may not be appropriate when the breeding objectives are to reduce N use.  Alternative methods of evaluating breeding materials, including regression analysis of grain protein deviation (GPD) and principal component analysis (PCA) were explored.  GPD was not found to discriminate well between genotypes in this study, but PCA...

The genotype by environment interaction study of broccoli,  amongst others  demonstrates that traits of a cultivar are sometimes ranked differently when grown in an organic production system compared to a conventional system. This has strong implications for breeding strategies. The breeders interviewed acknowledged that more attention on abiotic and biotic stress resistance in a broccoli breeding programme is needed which is in accordance with the farmers' varietal requirements. The first findings of the field trials show that cultivar performance is influenced by season and region, and differences in treatment (organic versus conventional management). The field trials showed that there are cultivars with broad adaptation such as "Green Goliath". These...

Plant associated soil microbes are known to play an important role in the expression and stability of certain plant traits such as nutrient use efficiency and disease resistance. Arbuscular mycorrhizal fungi (AMF) form one of the primary mutualistic plant-microbe symbioses. Besides known benefits such as improved nutrient mobilisation (mainly phosphorus and zinc) and tolerance against abiotic stresses (mainly drought), an increasing number of studies highlight a significant role of AMF in the mediation of disease resistances and priming mechanisms. Individual reports have shown enhanced levels of defence-related compounds (such as glucanases, chitinases and phenolics) in mycorrhizal plants, and there is first evidence of certain phytohormone pathways (in...

Breeding goats for organic production in Germany
Provedor de dados: 21
Autores: Rahmann, Gerold.
With only 120,000 females (year 2000), goat keeping is a niche activity in animal husbandry in Germany. Most of the goats (about 90%) are kept on part-time farms. The main reasons they are kept are as a hobby, for milk production and for landscape management; in many cases  it is a non-profit oriented activity. There are estimates (no official statistics exist) that 20,000 goats are milked and 10,000 are used in landscape management to avoid shrub succession on protected biotopes. In the year 2000 10% of the goats (12,000) were kept on organic farms but not all for economic reasons.    Because the dairy breeds in Germany (White and Brown German Alpine) are selected under intensive keeping conditions, breeding under the restrictions of organic farming is...

Autores: Nauta, Msc. W.J.; Saatkamp, Dr. H.; Baars, Dr. T.; Roep, Dr. D.
Abstract – Due to regulations organic farming is sub-jected to a different regime then conventional farm-ing. This results in different environments for ani-mals. The question is whether one overall breeding goal is sufficient to cover all different demands of organic farmers. A survey among 132 Dutch organic dairy farmers revealed that 55% of the farmers are specialized in milk production and 45% is running a multi-functional farm. The specialized milk production farms were significantly more intensive in farming compared to the multifunctional farms. Farmers from both strategies were also asked to value different breeding aspects of animals. In general farmers val-ued different aspects more or less the same: they wanted a robust, long living cow, with...

Organic strawberry production suffers from high yield losses caused by numerous fungal and bacterial diseases. Two of the most important diseases are the grey mould disease caused by Botrytis cinerea Pers. (teleomorph Botryotinia fuckeliana), and the bacterial angular leaf spot disease caused by Xanthomonas fragariae (Kennedy &amp; King). Beside cultivation methods and organic plant protection measures, the development of resistant cultivars seems to be the most promising strategy in order to improve the productivity in organic strawberry cultivation. Therefore, we established resistance tests to determine resistant and susceptible strawberry cultivars and breeding selections. In a first run, 40 different cultivars and selections were tested for their...

Breeding strategies for a spring barley pea mixed cropping system
Provedor de dados: 21
Autores: Haug, Benedikt; Messmer, Monika M.; Enjalbert, Jérôme; Goldringer, Isabelle; Forst, Emma; Mary-Huard, Tristan; Hohmann, Pierre.
Introduction and methods   Crop mixtures of cereals and legumes have received recent attention in the scope of climate change and local protein supply.   Cereal-legume mixtures are known to increase yield and yield stability compared with pure crops. Thus dedicated breeding strategies for mixed cropping might become necessary. As a model crop, we compared 32 current European spring pea (Pisum sativum L.) and 8 current spring barley (Hordeum vulgare L.) cultivars for their yield performance in mixed and pure stands, with pea as the focal species. Trials were done as an incomplete factorial design (Fig. 1) at two locations in  Switzerland with two replications (Fig. 2). We calculated variance components for the general and specific mixing ability (GMA and...

Breeding strategies in poultry for genetic adaptation to the organic environment
Provedor de dados: 21
Autores: Sørensen, Poul.
Regarding access to breeding material for laying hens to organic egg production the following can be concluded:  The breeding material available is genetically adapted to the cage systems. This cage adapted material has a shortcoming regarding behaviour in larger flocks that manifest in: too high tendency to feather pecking and cannibalism, and, independent of flock size, also to many mislaid eggs. Experiments has shown that feather pecking, cannibalism and nesting behaviour can be improved by selection. A search for alternative breeds/hybrids has not yet given the ideal "Organic hen". There seem to be a possibility for adaptation of laying bird to diets with lower crude protein that makes a production possible based on "home grown" crops even in Northern...

Bremia lactucae an Salat - Erarbeitung einer Entscheidungshilfe zur Sortenwahl
Provedor de dados: 21
Autores: Gärber, Ute; Idczak, Elke; Behrendt, Ulrike.
Erreger des Falschen Mehltaus an Salat ist der Pilz Bremia lactucae. Der Pilz besitzt eine hohe Variabilität und hat durch die Entwicklung neuer Rassen mehrfach die durch Züchtung erzielte Resistenz durchbrochen. Die Befallsgefahr hat insbesondere im ökologischen Anbau zugenommen, da direkte Regulierungsmaßnahmen fehlen. Die Entwicklung ständig neuer Erregerformen sowie das lokale Vorkommen einer Vielzahl an Erregerformen, erschweren dem Anbauer, die "richtige", resistente Sorte auszuwählen. Daher soll eine Methode erprobt werden, die es dem Anbauer ermöglicht, entsprechend der regionalen Anbausituation die Sorten auszuwählen, für die im Feld eine nur geringe Anfälligkeit zu erwarten ist.

Provedor de dados: 21
Autores: Francis, Charles; Nicolaysen, Anna Marie; Morse, Suzanne; Breland, Tor Arvid; Lieblein, Geir.
Bridging the large gap between science and experience of farmers is a crucial focus for educators who are intent on developing learning programs featuring phenomenology and practical experiences. Agroecology is emerging as an integrative and holistic approach to study agricultural and food systems. Understanding lessons learned from indigenous systems and the ecological principles on which they are built, focusing on the uniqueness of place in design and practice of farming, shifting from a discipline-specific to a holistic systems perspective, and integrating the human dimension into study of farming and food systems are all essential to building effective bridges between farmer experience and science as we practice this in university research and...

Students interested in achieving advanced education in agriculture and food systems using holistic, integrated approaches can find MSc programmes in Agroecology that meet such demand at universities such as UMB in Norway and ISARA in France. Many students now seek opportunities to pursue a PhD degree using a systems approach across disciplines. Interdisciplinary research in Agroecology is embraced by a dispersed group of researchers around the world, and few universities have their own capacity to offer adequate PhD courses and supervision for such interdisciplinary PhD training.  To design a new programme, we have established an international network of Agroecology researchers, advisors, and instructors from several universities in Europe, Africa, Asia...

BRIDGING THE GAP BETWEEN OLD AND NEW TECHNOLOGY: CONSIDERATION OF INDIGENOUS KNOWLEDGE IN MAIZE PESTS MANAGEMENT PRACTICES IN NIGERIA
Provedor de dados: 21
Autores: Meludu, Nkiru T.; Adesina, Jimoh B.
Conventional pests management practices are carried out mainly through extensive exposure to chemicals (pesticides) used in agricultural production. The overall ailing effects of these chemical based products to the environment and human health are some of the challenges which appeal to look for alternative farming practices that would minimize the use of pesticides in agricultural production. It is against this background that this study was carried out to determine the perception of the effectiveness of indigenous and organic maize pest management practices among maize farmers in Oyo state in order to bridge the gap between the old and new technology and determine the relationship that will enhance the development of ecological organic agriculture (EAO)....

Bridging the gap between scientific knowledge and practice: how can we assist organic farmers in sustaining wild bees and pollination on their farms?
Provedor de dados: 21
Autores: Langer, Vibeke.
Wild bees (bumblebees and solitary bees) are two important groups of wild pollinators in temperate zones, delivering pollination services to crops and wild plants. It is well documented that wild bees are declining nationally and regionally in Europe (Biesmeijer et al., 2006) threatening crop pollination estimated to 14 mia. euro/year. Wild bees are dependent on presence of high quality flower resources and on suitable nesting and overwintering sites locally (Strandberg et al., 2011). In the agricultural landscape, availability of these resources depend on land use, i.e. distribution between arable land and uncropped areas, crop distribution and management as well as quantity and quality of permanent grasslands, hedgerows, road verges, etc. Although...

Animal health status in organic dairy farming does not in all respect meet consumers’ expectations. Improvements are crucial to support consumers’ confidence and their willingness to pay premium prices. Considering animal health as an emergent property of the whole farm system the presented project aims to increase the implementation of evidence based measures and to improve practice of health management. This will be achieved by a multidisciplinary and participatory approach to develop farm specific solutions regarding preventive measures and appropriate treatment strategies.

Provedor de dados: 21
Autores: Vittersø, Researcher G.; Hegnes, Researcher A. W.; Jacobsen, Head of Research E.; Torjusen, Researcher H.
The point of departure for this paper is the observation that in spite of the public measures taken in order to increase the use of organic food in the out of home eating sector (the catering sector), there is little evidence that this sector has contributed to an overall increase in consumption of organic food. Our aim with this paper is not to discuss whether this is the case or not, but with an open mind we want to point at some factors or mechanisms that may explain the (lack of) connections between consumption of food within and outside of the home.

Bringing the principles of Organic Agriculture fully into practice can make organic the mainstream approach to sustainability

Autores: Gould, D.; Luttikholt, L.
The reality of the present world falls far short of the vision of a sustainable world: over-reliance on cheap, non-renewable energy, declining biodiversity, loss of fertile soils, rampant pollution, threatened water supplies, poverty and inequity. The Principles of Organic Agriculture encompass a broad vision of a better world, of social and environmental harmony. Only by considering all dimensions of sustainability – societal, ecological, economic, and cultural â€“ can we attain such a vision with a process of continuous improvements. By aspiring to best practices we take a path to an agriculture that can be sustained over the long term.

Bringt „Öko“ mehr Humus? Einschätzung der aktuellen Humusbilanzen der ökologisch und der  konventionell bewirtschafteten Ackerfläche in Deutschland
Provedor de dados: 21
Autores: Brock, Christopher; Leithold, Günter.
We calculated humus balances for organic and conventional cropland in Germany and compared them to each other in order to find out whether organic farming comprises a better humus reproduction than conventional farming, as commonly assumed. Applying a dynamic humus balance model that was parametrized based on data from agrostatistical reports we yielded comparable balances for the two farming systems. The reason was mainly a considerably lower stocking on organic farms, and the low N supply. However: a superior cropland structure brought the balance to the same level as with conventional agriculture despite of these factors. Due to shortcomings in model parametrization caused by the available data base, results may not be over-interpreted. Still, it can be...

Autores: Ferrante, Dr Valentina; Baroli, Dr Daniela; Lolli, Dr Susanna; Di Mauro, Dr Francesca.
Animal welfare, product quality and organic or niche production system rise to more and more interest. Organic farming has grown rapidly in European and Italian agriculture during the last decade. The aim of the trial was to compare five organic and five conventional broiler  farms from the productive, health and behavioural point of view. The productive performance showed that conventional broilers (CB) consumed significantly less feed then organic broilers (OB) and the first got a better FCR.. These different figures could be due to the different environment and life style. OB are more exposed to natural climate, they can move much more and then they increase feed consumption and FCR become worsen.  The different age at slaughter determined the...

Common bunt is infecting wheat seedling just after sowing, in the heterotrophic phase before seedling emergence. The seed per se is healthy at the time of sowing, but gets infected from spores resting on the seed surface.  Bechel et al. 1998 has shown that only a minor fraction of the spores of the the closely related bunt species T.contraversa in a seed lot end up in the flour, while the majority are removed during the cleaning of the seed before or during milling. However, little is known about the destiny of the spores during the cleaning process of seed intented for sowing.

Habitat quality of different arable crops for skylarks (Alauda arvensis) was analysed in  a three year field study on 12 organic farms in northern Germany. Grass clover,  spiked spring cereals (barley/spelt/wheat), winter wheat as well as grain legumes  (including mixtures) hold constant abundances of skylarks during the whole breeding  period. In spring oats, winter spelt and winter cereals with awn (barley/rye), however,  skylark densities decreased during the breeding time, which might be explained by  comparatively taller and/or denser vegetation structure of theses crops during  June/July. Crops showed no significant differences in maximum abundances of  skylarks. Concerning possible effects on breeding success, harrowing and/or hoeing  of cereals and...

Buchweizen: ein Futtermittel für Legehennen?
Provedor de dados: 21
Autores: Leiber, F.; Messikommer, R.; Meier, J.S.; Wenk, C.
Buckwheat (Fagopyrum esculentum) has a high ecological value due to the long and  intensive flowering as well as its favorable impact on soil fertility. In addition, as a  typical catch crop, it provides the possibility of a second harvest on arable land in  moderate European regions. However, in Europe demand for buckwheat kernels as  food is low. Therefore, the question arises whether cultivation of this plant could be  promoted by using it as animal feed. In the current experiment, the extent to which  buckwheat is consumed by laying hens was tested in conjunction with potential effects  on egg yield and quality. Three groups of laying hens (n=13 per group) were fed a  layer diet containing either 40% wheat, 40% hulled buckwheat or 40% crude buckwheat....

Interest in buckwheat has incresed due to it being a valuable raw material for functional food production. It has been reported to have general beneficial effects on health.    Buckwheat competes well with weeds and suffers little from other pests. This may be because buckwheat contains allelopathic compounds and its cultivation was observed to reduce weed biomass. Its soil nutritional requirements are low.

Water repellency index R was measured in a heavy clay and a sandy loam, used as arable land or buffer zone (BZ). Further, effect of management practise and ageing of BZs were studied. Water repellency was proved to be a common phenomenon on these soils. Harvesting and grazing increased water repellency as does ageing.Low water repellency is supposed to prevent preferential flows and provide evenly distributed water infiltration pattern through large soil volume, which favours nutrient retention.

While the built environment responds to the needs of adults, it is sufficient to shrink the built environment to children’s scale. At that point, the importance of the natural habitats of the city comes up to balance the difference of this scale. In this study, the relationship between children and the natural habitat is examined with a practice based on the permaculture strategies. Permaculture has different application areas. Although, rural areas are the most preferable space to implementation, to repair bonds, which are severed from nature by modern life, meaning also from earth, permaculture should be applied in urban areas.

The content of alfa-linolenic acid of the Finnish samples was among the highest compared with results from several international studies (reference value 57,0 %, Morris 2003). The composition of fatty acids, especially unsaturated fatty acids, reported in different studies varies considerably. This variation depends mainly on differences in the examined varieties and in industrial processing treatments.

Autores: Bloksma, Joke; Jansonius, Pieter Jans.
Die positive Korrelation zwischen einem hohen Kalziumgehalt in den Früchten und guter Qualität wird von der Literatur zusammengefasst. Die traditionellen Kalziumspritzungen sind nicht ideal (Synthetische Ursprung, Schalenberostung, Sonnebrand). Wir forschen nach Möglichkeiten für Obstbauern weniger abhängig zu sein von Kalziumchlorid und doch qualitatives Obst zu bekommen.  Bei unserer Beurteilung der Kulturmaßnahmen in Bio Obstbau ist der Kalziumgehalt der Früchte eines der Kriterien. Positiv in diesem Rahmen haben sich gezeigt: ein lebendiger Boden, Begrünung, besonders Klee, Begrenzung des Wuchsniveaus, gute Qualität Rosettenblätter, Früchte an der Basis des Triebes und Früchte mit viele Samen.

Calf rearing in organic dairy production
Provedor de dados: 21
Autores: Johnsen , Julie Føske; Ellingsen, Kristian; Grøndahl, Ann Margaret; Mejdell , Cecilie Marie.
Organic farmers utilize a wide variety of practices for suckling and separation of cows and calves, and experiences vary. This constitutes an important resource for finding and testing management practices that may improve animal  welfare and diminish stress at separation. Farmers’ increased awareness of their animals’ behaviours may  provide improvements in welfare and production in the years to come.

Campylobacter species distribution in outdoor pigs: Oral presentation O44
Provedor de dados: 21
Autores: Jensen, Annette Nygaard; Nielsen, Eva Møller.
A colony blot hybridization method with a digoxigenin-(DIG)labelled nucleotide probe was developed to enable Campylobacter jejuni species-specific identification of colonies present in minority. C. jejuni is the dominant cause of human cases of Campylobacteriosis. In contrast, C. coli is normally dominant in conventional pigs but it can be speculated that outdoor pigs host more C. jejuni due to a closer contact to the environment and wild-life where C. jejuni is pre-dominant. Since C. jejuni is considered more virulent to humans a potential shift towards C. jejuni in pigs may infer an importance to food safety. Individual pigs are often colonized with several Campylobacter strains. However, with conventional culturing techniques only few colonies are...

Autores: Fauriel, Joël; Bellon, Stéphane; Plénet, Daniel; Amiot, Marie-Jo.
Peach production in the Rhône-Alps region is increasingly challenged by mediterranean European regions. A possible regional strategy would consist in the development of qualification signs. A significant part of the peach production is already labelled (CCP, Red Label, Organic). How such labels relate with quality attributes at field level ? Can polyphenols be considered as an asset in a re-qualification process of peach production?     To contribute to these issues, we present preliminary results derived from field work in Rhône-Alps. The study was conducted on 12 orchards of yellow peach (cv Spring Lady) in farms. 10 orchards were managed according to the above mentioned specifications while 2 were cultivated without specifications.

Can ants control plant diseases?
Provedor de dados: 21
Autores: Offenberg, Joachim.
Ants are challenged with disease transmission and microbial hygiene due to a life in densely populated long-lived ant nests. To improve hygiene ants use different ways to reduce microbial growth. They groom their bodies with (i) antimicrobial excretions from their metapleural and poison glands, they (ii) associate with bacterial symbionts capable of producing antibiotics, or they (iv) eat microbial spores. These defenses extend beyond the individual ant, as ants may groom nest mates, food substrates or nesting material. Defenses may even extend beyond the nest and affect mutualistic partners. For example, ants in specialized myrmecophytic ant-plant interactions have been shown to reduce pathogen loads on their host plants. Here we tested if wood ants...

The paper explores whether an organic control system could include elements of an improvement standard as compared to the current minimum requirement standards. It is based on a review of rules of organic certification and of literature. The discussion explores whether an approach of agreeing individual improvement targets between operator and certification body could allow the consideration of some areas of the organic principles that are currently not audited in the form of minimal certification requirements. Such a system would allow the determination of whereof whether an operator is on the way to making improvements and strengthen operators’ responsibility.

Can higher legume diversity reduce clover soil fatigue?
Provedor de dados: 21
Autores: Søegaard, Karen; Møller, Kaare.
White clover soil fatigue is an increasing problem in Danish organic dairy farms. The clover cyst nematode (Heterodera trifolii) has been found to play a major role in the problem. Grassland legume species less readily attacked by H. trifolii and less favourable for its reproduction than white clover may offer possibilities for relieving the soil fatigue.    In 2005, screenings were made of nine grass-land legume species / varieties in a field with a rather high level of H. trifolii infestation, pre-cropped with grass/white clover, and in a field with a low infesta-tion level, pre-cropped with maize.    The species grouped in two: 1) White, red, alsike and kura clovers and lucerne had medium to high percentages of nematode attacks and numbers of nematodes...

Can managed grasslands enhance pollinators in intensively farmed areas?
Provedor de dados: 21
Autores: Dupont, Y.L.; Cong, W-F; Eriksen, J.
Wild flower strips is a common agri-environmental scheme used by farmers and land managers in order to improve biodiversity of pollinators. However, managed grasslands may also provide flower resources for flower visiting insects in agricultural landscapes. Botanically diverse grasslands on arable farms may support a range of wild pollinators, enhancing pollination services of crops. Intensively managed leys, on the other hand, typically contain only a few high-yielding, competitively strong species.     One of the aims of the Multiplant project (2014-2018) was to test perennial seed mixtures targeted for bio-energy, feed protein and biodiversity, in order to develop multi-functional seed mixtures for grasslands.

Autores: Kristensen, Hanne L.; Xie, Yue; Bavec, F.; von Fragstein, Peter; Campanelli, Gabriele; Ortolani, Livia; Canali, Stefano.
To secure a sustainable production of plant foods for the future, there is a need to develop new cropping systems. These systems should have reduced needs of external resources and reduced environmental impact, while product yields are maintained at high level. Therefore, field trials were performed in Italy, Slovenia, Germany and Denmark with the aim to study new organic cropping systems for production of vegetable crops; and the systems’ effect on labor and energy consumption and the risk of losing nitrate to the water environment. The cropping systems included an in-season living mulch to exploit ecosystem services by attracting beneficial insects, suppressing weeds, and taking up excess nitrogen during production of two high-value crops of leek and...

Policy support for organic farming in the UK is based in part on the ability of organic farming systems to deliver natural heritage benefi ts. Most UK research on the natural heritage benefi ts of organic farming has addressed lowland arable systems. A reanalysis of a subset of data from a MAFF-funded study of biodiversity in England and Wales suggests that organic systems in predominantly pastoral landscapes may show similar biodiversity benefi ts to ones in predominantly arable landscapes. Future research needs to address organically managed pastoral, hill and upland systems across the UK.

Can parasitic gastro-enteritis be used as an indicator of welfare in organic sheep?
Provedor de dados: 21
Autores: Gray, Douglas.
This report was presented at the UK Organic Research 2002 Conference.  Organic livestock standards are designed to deliver good animal welfare but without an objective means of assessing welfare, it is difficult to know if they succeed. Existing assessment systems largely assess environmental requirements, rather than looking at animal behaviour or health. Parasitic gastro-enteritis (PGE) is recognised as being one of the most difficult diseases to prevent in organic livestock production. Monitoring systems for PGE can be used by organic farmers in their decision-making and could be one aspect of assessing animal welfare, particularly in relation to sheep. Results are presented of studies on an experimental organic beef/sheep farm and on commercial organic...

Can Sweet Sorghum and Sweetpotato Ethanol Contribute to Self-Sufficiency of Small Farms?
Provedor de dados: 21
Autores: Bomford, Michael K.; Silvernail, Anthony F.
Sweet potato (Ipomoea batatas L.) and sweet sorghum (Sorghum bicolor L.) are promising crops for advanced biofuel production because they are better suited than corn (Zea mays L.) to low input production on small farms in the south. They can be considered advanced feedstocks only if lifecycle greenhouse gas emissions are less than 50% of basoline baseline emissions. Both sweet potato and sweet sorghum are multifunctional crops, with potential to simultaneously produce human food, animal feed, and biofuel feedstock. Kentucky State University is exploring the potential for organic production techniques and decentralized processing systems to reduce lifecycle greenhouse gas emissions of energy produced from these crops at a range of small farm scales.

Can water quality problems motivate conventional farmers to convert to organic farming?
Provedor de dados: 21
Autores: Vincent, Audrey; Fleury, Philippe.
Recently, the conservation of water resources has become a major issue because of the increasing problems of water pollutions by agriculture. In this context, organic farming (OF) is seen by some institutions as a promising solution for responding to this problem because of its regulation that prohibits the use of chemical fertilisers and pesticides. Recent policies in France have focussed on promoting OF development, especially in water catchments’ areas contaminated by pesticides. Our hypothesis is that the existence of a water quality problem locally can be a motivation for conventional farmers to convert to OF. This research is based on 65 farmers’ interviews (mainly conventional farmers and a few farmers who recently converted to OF) that were carried...

Can weed management in vegetable systems be improved by cover crop species mixture? Step 1: Screening of cover crop species and varieties
Provedor de dados: 21
Autores: Ranaldo, Marzia; Costanzo, Ambrogio; Carlesi, Stefano; Barberi, Paolo.
Cover crops are an essential strategy in organic and low input arable and vegetable production, especially regarding weed reduction and N use efficiency, but their establishment and development can be unstable. A viable option to enhance and stabilise the agroecosystem services provided by cover crops is to sow mixtures of species having different functionality. Such mixtures have been reported to increase productivity, stability, resilience and resource use efficiency of cover crop communities. Therefore, our hypothesis is that weed reduction can also be improved by cover crops mixtures. However, it is not yet clear how diversity drives these mechanisms in arable and vegetable systems in Mediterranean climates.

Capacity building and public awareness raising on Nitrates Directive in the countries aspiring to EU accession
Provedor de dados: 21
Autores: Znaor, Darko; Karyotis, Theodore.
The governments of the EU Member States have agreed to potentially enlarge the Union with seven South East European countries (Croatia, the Former Yugoslav Republic of Macedonia, Albania, Bosnia and Herzegovina, Montenegro, Serbia, Kosovo under UN Security Council Resolution 1244) and Turkey. However, these countries will be granted full member status only when all political, legislative and administrative requirements for membership are fulfilled. Transposition, implementation and enforcement of the EU Nitrate Directive (91/676/EC) is one of these requirements.    Many policy makers, farmers and consumers from the EU accession countries perceive the Nitrate Directive as a very demanding piece of legislation with little relevance for their countries....

Capacity of Deep Rooted Species to Take Up Water and  Nutrients from Deep Soil Layers
Provedor de dados: 21
Autores: Dresbøll, Dorte Bodin; Rasmussen, Camilla Ruø; Thorup-Kristensen, Kristensen.
Introduction  Agricultural cropping systems generally have a limited use of water and nutrients from the soil below 1m depth. However, several plant species have much deeper root systems, and if included in cropping systems, these would allow for exploitation of otherwise unused resources from deep soil layers. In a unique facility consisting of 12, 4m high ‘root towers’ we examined the root development and root activity in different soil layers of different biannual/perennial plant species.    Methods  Four plant species lucerne (Medicago sativa), rosinweed (Silphium integrifolium), intermediate wheatgrass (Thinopyrum intermedium), and dyers voad (Isatis tinctoria) were grown in soil in large rhizotrons (root towers) (4m×1.2m×0.6 m). Root growth was...

Carabid beetles (Carabidae) in agroecosystems - case study on the effects of conversion to organic farming and land structure
Provedor de dados: 21
Autores: Sarapatka, Bořivoj; Vesely, Milan.
Our research compared the effects of farming systems (conventional, conversion to organic farming, resp. organic farming) and land structures (ecotones) on carabid beetles in four experimental plots during a five-year crop rotation cycle. An important factor affecting the composition of carabid communities was the type of land fragmentation contributing to a faster colonization of fields from ecotones. The factor of agricultural management, organic farming, was also significant. In the final years of the experiment we noted changes in the species composition of the carabid communities compared with the first years of the experiment, with an increase in the preference of bigger carabid species. The abundance of large carabid species was much lower in...

Provedor de dados: 21
Autores: Jørgensen, Henry; Bach Knudsen, Knud Erik; Lauridsen, Charlotte.
Environmental as well as cultivation factors may greatly  influence the chemical composition of plants. The main factors affecting chemical composition of foodstuff is level and type of fertilizer (conventional and organic cultivation systems), location or soiltype and year of harvest. Organic foods are defined as products which are produced under controlled cultivation conditions characterized by the absence of synthetic fertilizers and  very restricted use of pesticides.   Dietary carbohydrates constitute a major fraction of most feedstuffs and can be divided according to glycosidic linkage into sugars (mono- and disaccharides), oligosaccharides, starch and non-starch polysaccharides (NSP). The bulk of disaccharides and starch will be broken  down by the...

Autores: Kauppinen, Tommi; Katajajuuri, Juha-Matti; Pesonen, Inkeri; Kurppa, Sirpa.
This paper identifies the primary consumer actions having an effect on carbon footprint, their relative importance and their sensitivity to consumer choice concerning food maintenance. Food maintenance (transportation, preservation and preparation of food) of a Finnish household produces annually 170 kilograms of CO2-equivalent per individual as an average which corresponds approximately 2 % of the greenhouse gas emissions of private consumption. Of transportation, preservation and preparation, we find the preservation as the most important source of greenhouse gas emissions.

Carbon sequestration in organic and conventional managed soils in the Netherlands
Provedor de dados: 21
Autores: Sukkel, Wijnand; van Geel, Willem; de Haan, Janjo.
Next to other important agronomic and ecological aspects, the organic matter sequestration in the soil plays an important role in the CO2 balance. Based on detailed farm registrations, the input of effective organic matter and the changes in carbon sequestration in the soil was calculated for a large number of organic and conventional farms in the Netherlands. Results show that both organic and conventional management resulted in a decrease of the pool of organic carbon in the soil. The average decrease for the conventional management was 401 kg ha-1 year-1 and for the organic management 261 kg ha-1 year-1. The input of effective organic matter in the soil was significantly higher in organic than in conventional farms. Animal manure was the main...

Carcass and meat quality of different pig genotypes in an organic extensive outdoor fatting system
Provedor de dados: 21
Autores: Weissmann, Friedrich; Fischer, Klaus; Biedermann, Günter.
Carcass, meat, and fat quality were evaluated of 37 castrates of 4 different genotypes [Pi*Du*GLR (10), Pi*AS (7), Du (10), Du*GLR (10)] kept on grass clover and fed with coarse meal made up of farm grown cereal and grain legumes without optimising the amount of amino acids and their relation to the energy content. Due to the energy surplus in the diet and in relation to the diminishing muscularity of the genotypes (corresponding to the above-mentioned sequence) lean meat contents were on a low level whereas intramuscular fat contents increased distinctly. Sensory meat quality was only at a medium level and did not differ noticeably between the genotypes. It is concluded that adipose carcasses associated with increased intramuscular fat contents do not...

Carcass quality of organic pork
Provedor de dados: 21
Autores: Sundrum, Albert.
According to the Council Regulation (EC) No 1804/1999), organic livestock production is intended to ensure quality production rather than maximising production. In organic pig production, the availability of limited amino acids is the first limiting factor and the main reason why the performance capacity is clearly diminished compared to conventional production. In order to compensate for the lower productivity, quality production is a conditio sine qua none. Possibilities to improve the quality of organic pork were investigated in different feeding trials. Results from a first trial in 1999 showed that diets based on organic cereals and home grown grain legumes (faba beans, peas and lupines) have the potential to produce pork with a high intramuscular fat...

Carrot or stick? – Would information concerning the economic value of nutrient losses, and their impact on food quality achieve greater environmental protection than regulation?
Provedor de dados: 21
Autores: Fowler, Susan M; Philipps, Lois; Watson, Christine A.
This report was presented at the UK Organic Research 2002 Conference. Organic standards have, since their origin (Soil Association 1967) required high standards of manure management, but in reality, these have not been implemented, possibly because of perceived costs of improved handling. However, a cost/benefit analysis of intermediate steps of nutrient conservation and manure handling may provide a practical solution, optimising retention of nutrients, financial and time inputs and environmental protection. Recent research on composting with conventional manures has quantified nutrient losses from heaps with different treatments (Parkinson et al, 2001). Financial and environmental costs and benefits of different management approaches are discussed.

Industrialised chicken production is far from organic agriculture prinicples. Still of interest is a more sustainable utilisation of by-products, e.g. hydrolysation of feathers for proteins, or extraction of food grade oil from chicken bones.

Provedor de dados: 21
Autores: Adler, Steffen A.; Løes, Anne-Kristin; Rommi, Katarina; Kambestad, G; Albrektsen, Thor-Erik.
During processing (packaging) of vegetables and potatoes, large proportions are sorted out due to minor damage or deviations from strict visual standards. Out-sorted products are poorly paid, and have a short shelf-life. Processing to increase the payment and shelf-life may support a more sustainable utilisation of these by-products. Conserving as silage is one option, which was  studied in the bioeconomy-project "CYCLE" (2013-2017). Other approaches are also discussed.

Catch Crops in Organic Farming Systems without Livestock Husbandry - Model Simulations
Provedor de dados: 21
Autores: Müller, Dr. Torsten; Magid, Dr. Jakob; Jensen, Dr. Lars Stoumann; Nielsen, Dr. Niels Erik; Thorup-Kristensen, Dr. Kristian.
During the last years, an increasing number of stockless farms in Europe converted to organic farming practice without re-establishing a livestock. Due to the lack of animal manure as a nutrient input, the relocation and the external input of nutrients is limited in those organic cropping systems. The introduction of a one-year green manure fallow in a 4-year crop rotation, including clover-grass mixtures as a green manure crop is the classical strategy to solve at least some of the problems related to the missing livestock. The development of new crop rotations, including an extended use of catch crops and annual green manure (legumes) may be another possibility avoiding the economical loss during the fallow year.   Modelling of the C and N turnover in...

Cation-anion balance in organic silage in relation to prevention of milk fever
Provedor de dados: 21
Autores: Henriksen, Britt I. F.
Studies of organic farms in Norway have documented that cows in organic herds are less prone to milk fever compared to the overall average incidence of milk fever in Norway. Milk fever occurs most frequently in high-yielding cows, fat cows and older cows. On average, cows on organic farms are lower yielding, but also older. Dry cow diets relatively high in the anion chloride (Cl–) and low in the cations potassium (K+) and sodium (Na+) can prevent milk fever. In organic farming no inorganic fertilisers are used. This may result in low content of K in the plants and with that a low content of K in the fodder. Often there also is greater diversity of plants (clover, herbs, “weeds”) in an organic meadow than in a conventional meadow. Plants vary in their...

Cattle production in agroforestry systems. An analysis on the role of intensification and dependence of subsidies
Provedor de dados: 21
Autores: Escribano, A.J.; Gaspar, P.; Mesias, F.J.; Rosas, J.P.; Escribano, M.
Extensive livestock production systems have faced socio-economic factors (such as the loss of profitability and competitiveness) that have led to modifications in their management and structure. The main changes have been the abandonment of grazing, the increase in the use of external feed, the abandonment of farms, and the intensification of the systems.  The dehesa is the consequence of human intervention in the natural Mediterranean forest. Due to this, the conservation of this ecosystem depends on the use of appropriate agricultural practices (Gaspar et al., 2007). Thus small changes in the production systems may have a great impact on its conservation and on the rural population. As consequence, the intensification of farms and the high prices of...

Cattle trampling reduces the risk of nitrate leaching in organic dairy rotations
Provedor de dados: 21
Autores: Lamandé, M.; Eriksen, J.; Krogh, P.H.; Jacobsen, O.H.
Organic dairy farming is characterized by grazing cows in contrast to Danish conventional farms where the majority of cows are kept indoors. Cattle trampling reduces the finer macroporosity in the top 5-10 cm of the soil. This causes a low infiltration capacity at the soil surface, giving a higher probability of macropore flow from the surface. Rapid water movement through macropores bypasses the soil matrix, reducing nitrate leaching. We investigated how three years of cattle trampling in organic grass-clover fields could influence the risk of nitrate leaching in the autumn. The experimental part of this study was situated in Denmark on a loamy sand within a long-term organic dairy crop rotation trial. Experimental plots were irrigated with a concentrated...

Cereal breeding strategies for organic and low-external-input crop production systems
Provedor de dados: 21
Autores: Acikgoz, Prof. Dr. Nazimi; Ilker, Dr. Emre.
Increasing trend in organic farming does not seem to have yet attracted the attention of many plant breeders. On the other side, in every cropping system, for every species, best performing cultivars are needed in each macro-ecology. Considering dif-ferent cropping systems, such as open or glasshouse production, main or second crop alternatives, plant breeders have to focus on the genotype-environment and genotype-input interactions.   Organic farming is in need of tailor-made genotypes for almost every crop. In fact, in the near future the same amount of organic registered cultivars will be needed as the conventional cultivars.  Conducting an immediate single or combined “seed-bed – pot – field test” might be a logical start to de-termine organic...

CERTCOST – Economic Analysis of Certification Systems for Organic Food and Farming at EU level
Provedor de dados: 21
Autores: Dabbert, Prof. Dr. Stephan; Lippert, Dr. Christian; Schulz, Ms. Tatjana; Zorn, Mr. Alexander.
With the ongoing growth of the organic sector and the spread of organic production across the EU, the field of organic certification has become a maze of competing labels and logos. This diversity reflects the specific conditions in different regions and countries, but can also lead to confusion for producers and consumers, as well as create a variety of costs. It is imperative to conduct a comprehensive economic analysis of the variety of existing certification systems and their impact on the internal European market for organic goods. This project proposes to combine the experience and knowledge of both researchers and SMEs to analyse the implementation of organic certification systems and to estimate all relevant expenditures or transaction costs for...

Certified Organic Forests &amp; Timber: the Hippocratic Opportunity
Provedor de dados: 21
Autores: Paull, John.
Organic farming was proposed in 1940 by Lord Northbourne as a response to chemical agriculture. Since then, organic agriculture has developed into an international A$50 billion industry with annual growth reported up to 30%. Currently it is one of the fastest growing food sectors with demand exceeding supply in many markets, and price premiums averaging 80% in Australia. With economic, and now environmental, incentives for planting trees, there is the opportunity, and even imperative, for a new silviculture category that embraces the precepts of organic agriculture. There are environmental, economic and ethical issues with carbon offset programmes that seek to reduce, or erase, the carbon footprint of an activity, while collaterally increasing the...

Autores: Escribano, A.J.; Gaspar, P.; Mesias, F.J.; Escribano, M.; Pulido, A.F.
The livestock sector must be redesigned in order to achieve food security sustainably. Several authors have argued that organic farming may contribute positively in this sense. However, the externalities of the organic livestock systems are influenced by several factors. Due to this, the aim of this paper is to shed light on the needs and perspective of the organic beef cattle farms located in the 'dehesa' ecosystem (SW Spain). For this purpose, we created the 'Feasibility of Success Index' (FSI) by using indicators that took into account the context of the extensive livestock systems located in the Mediterranean basin. Two groups of organic farms were analyzed: farms that sold calves at weaning age a conventional ones (Organic); farms that fattened and...

Challenges for avoiding and handling disease problems in organic herds
Provedor de dados: 21
Autores: Kijlstra, Prof. Dr. Aize.
Disease prevention in organic farming is based on the principles that an animal that is allowed to exhibit natural behaviour, that is not subjected to stress and that is fed optimal (organic) feed, will have a higher ability to cope with infectious insults than animals reared in a conventional manner. Less treatments would thus be necessary and if an animal would become diseased, alternative treatments instead of conventional drugs should be preferred. Homeopathy or phytotherapy are recommended according to the prevailing regulations. The presumptions mentioned above have not yet been substantiated by scientific evidence. No data are available showing that disease prevalence of animals held under organic conditions is lower than under conventional...

Challenges in organic egg-production related to the nutritional quality of foraging material and introduction of 100% organic feeding
Provedor de dados: 21
Autores: Steenfeldt, S.; Hammershøj, M.
Organc hens have daily access to foraging material and the quality are important for egg-production due to varying contents of amino acids (aa) and dietary fibres (Hammershøj and Steenfeldt, 2005; Steenfeldt et al., 2007). Supplying organic hens with appropriate amounts of protein and aa can become problematic with the introduction of 100% organic feed from 2012. The interest in growing protein sources nationally has increased in Denmark in consideration of the environment. Growing soybeans nationally would reduce import. Present hen genotypes used in organic egg-production have high nutrient-requirement, so using genotypes with lower protein-requirements could have some interesting perspectives.

Autores: Marshall, Athole H; Humphreys, Mervyn O.
This report was presented at the UK Organic Research 2002 Conference. The demand for organically produced forage seed is increasing rapidly as organic livestock farming expands. EU regulations stipulate that from 1 January 2004 organically produced seed must be used in organic production systems. The production of forage seed in an organically acceptable manner to meet the current Seed Certification standards is a significant challenge to the seed producer. Conventional systems of grass seed production use inorganic nitrogen applied at specific stages of crop development and appropriate use of herbicides to produce high quality seed, reduce weed content and minimise seed cleaning costs. The development of organically acceptable methods of weed control and...

Challenges in Transitioning to Organic Farming in West Bengal, India
Provedor de dados: 21
Autores: Brodt, Sonja; Schug, Donald.
This paper uses a case study of small-scale rice and vegetable producers in West Bengal, India to argue that some of the same infrastructural and technical roots to problems that plague small farmers attempting to use chemically-intensive farming methods also hinder their ability to fully convert to global-style organic farming. In particular, problems in accessing knowledge and technical inputs are likely to translate into difficulties in adopting and maintaining organic production practices. This case study raises the question of whether the global organic model, which is highly dependent on specialized, knowledge-intensive techniques and expensive inputs, offers a true alternative for the developing country context. A locally developed model based on...

Autores: Hallmann, Dr. Johannes; Buck, Holger; Rau, Florian; Daub, Dr. Matthias; Schütze, Dr. Wolfgang; Grosch, Dr. Rita; Schlathölter, Michaela.
Biofumigation is considered a promising nematode control alternative. In vitro tests  confirmed the high nematicidal properties of isothiocyanates, the driving compounds  of biofumigation. Its potential under temperate climate conditions was tested on a  commercial farm. The tested biofumigation treatments reduced population densities of  Pratylenchus spp. but had little effect on Meloidogyne hapla. The latter was most likely  due to the good status of the tested varieties. To further optimize the biofumigation  system non-host crops with high concentration of glucosinolates have to be selected.

Organic Participatory Guarantee Systems (PGS) may be on important contribution to Organic 3.0. The way that PGS systems are managed can be a major determinant of their success. In Northern Vietnam differing management of PGS systems can determine their level of social and ecological success, as well as the impressions of farmers and retailers. Nevertheless, more farmers’ groups are turning to individual management and this may have negative consequences for the future of PGS in the region.

Nine batches of cooked sliced emulsion type sausages, produced from organic meat with or without the use of nitrite, were packed under N2/CO2 (7:3) and vacuum, respectively, and stored at 8°C. During two weeks of storage, the microbiological quality was determined, as well as the sensory quality by using profile analysis. The spoilage flora consisted of lactic acid bacteria and Brochothrix thermosphacta, without clear evidence of an inhibitory effect of nitrite on the growth of these organisms. The sensory profile showed an increase of the sour and rancid aroma and flavour, in parallel to the growth of these microorganisms. These changes were more pronounced in the batches prepared without nitrite. Spots of red discolourations were occasionally observed...

Bioenergy production from local bioresources has a great potential. It is important to reduce dependency on fossil fuels and decrease green house gas emission in organic agriculture (OA). Both biogas and bioethanol can be produced in OA and significantly contribute to the sustainability of organic farms. Soil fertility is the basis for OA: it has been of concern that the fertility might decline if most of the organic residues were converted into energy and only effluent from anaerobic digestion process was recycled. However, by intelligent management of organic residues and crop rotation it is possible to avoid decrease of soil fertility and at the same time produce renewable energy.

Abstract from a DAFINET workshop:    For many years it has been known that the bacterial microflora in the gut of warm-blooded animals live in harmony with the host and exert various beneficial effects on the health by their metabolic activities. Hence, the gut microbiota has a high importance for the animal. In many studies from e.g. humans and the pig mapping of the bacterial flora from the gut have shown dominance by some specific bacterial groups, and this bacterial profile is termed as a ‘core microbiota’. For lower vertebrates like fish mapping of the bacterial flora in the gastrointestinal system is to date a relatively new research field and previous studies have mainly been done on bacterial species that can be cultured or by classical molecular...

Characteristics of Organic Pig Production and risk analysis concerning Toxoplasma infection
Provedor de dados: 21
Autores: Kijlstra, A.; Cornelissen, J.B.; Meerburg, B.G.
A short written questionnaire was used to study certain characteristics of the organic pig production chain in The Netherlands and the circumstances on the farm that might play a role in the transmission of Toxoplasma infection to the pigs. Of the 81 certified organic slaughter pig farmers present in the Netherlands in 2006, 52 responded to the questionnaire (64 % response).  The farms could be divided into two populations. One population was represented by small organic pig farms with a mean number of 55 slaughtered pigs per year. These farms covered 40% of the total number of investigated farms, but only represented 2.5 % of the total number of slaughtered pigs. The second population had a mean annual production of 1460 animals. Almost 95% of these...

Characteristics of spring barley varieties and crop diversity for  organic farming and variety testing
Provedor de dados: 21
Autores: Østergård, H.; Jensen, J.W.
Results from Danish spring barley variety trials including about 50-120 varieties and variety mixtures on three locations over three years under organic as well as conventional farming systems demonstrate the importance of genotype-environment interactions. This has implications for potential future organic VCU-testing; here results are shown for grain yield. Further, grain yield results from of six variety mixtures and their 14 component varieties indicate that variety mixtures may be less influenced by genotype-environment interactions compared to pure line varieties.

Characteristics of spring barley varieties for organic farming
Provedor de dados: 21
Autores: Østergård, Hanne.
Modern spring barley varieties have been developed with the aim of combining high productivity and standardised product quality under high-input conditions using pesticides for control of weeds, diseases and insects as well as heavy application of nutrient-rich and water-soluble inorganic fertilizers. In the organic growing system, biotic and abiotic stresses have to be overcome by growing the appropriate varieties and by practicing good farm management. The important spring barley traits to be considered in organic farming are related to the inherited viability and adaptation of plants to survive biotic and abiotic stresses and includes competitive ability (morphology, weed tolerance, growth rate, allelopathy), disease resistance (morphology, specific and...

CHARACTERISTICS OF VALUE BASED FOOD CHAIN IN ORGANIC SECTOR  (case studies from Slovenia)
Provedor de dados: 21
Autores: Prišenk, Jernej; Borec, Andreja.
In the literature the value based food chains express two main characteristics: business relationships among strategic partners interacting in the supply chain are based on a written set of values and food products are differentiated from similar food products based on product attributes such as food quality, safety, and/or functionality along with environmental and social attributes (Stevenson, 2009). To verify the first part of the definition the analysis of two organic food chains where carried out. For the analysis of business relationships and food quality communication in the food chain two different methodological approaches were used. For collecting the input data a semi-structured interviews with various stakeholders were performed. The results of...

Die Resistenzzüchtung gegenüber Weizenflugbrand (Ustilago tritici) hat in den letzten Jahren aufgrund der Ausdehnung des ökologischen Landbaus, der eine Bekämpfung mittels chemischer Saatgutbeizung nicht zulässt, zunehmend an Bedeutung gewonnen. Ziel eines im Rahmen des „Bundesprogramm Ökologischer Landbau“ geförderten Projektes war es daher, Resistenzen im deutschen Weizensortiment, als Basis für eine direkte Nutzung dieser Sorten im ökologischen Anbau bzw. als Ausgangspunkt für eine gezielte Resistenzzüchtung, zu identifizieren.

Attack with common bunt (Tilletia caries) is a potential threat to wheat production in organic farming. The situation may even become worse if (in agreement with EU-legislation) only organically produced seed is used in organic farming. The targeted use of resistant varieties could be a way to alleviate the problem. However, knowledge regarding bunt resistance of wheat varieties on the one hand and aggressiveness in populations of the bunt pathogen on the other hand is still insufficient. In the frame of a federal research programme for organic farming (BÖL),30 winter wheat varieties and breeding lines were studied at five different locations using spores of local origin in order to assess the natural level of resistance (WÄCHTER et al. 2004).

Autores: Athmann, Miriam; Kautz, Timo; Köpke, Ulrich.
More information on root growth in biopores is needed for quantifying nutrient acquisition from the subsoil. The article presents an approach for using in situ endoscopy in biopores that allowed to quantify root-soil contact and detect differences in root morphology and orientation between mallow (Malva sylvestris L.) and spring wheat (Triticum aestivum L.). While 85 % of all wheat roots entered the biopores laterally from the bulk soil, mallow roots in biopores grew predominantly (69 %) with vertical orientation and established contact to the pore wall predominantly via lateral roots. The current status and future perspectives of the method are discussed.

One of the key issues in organic vegetable production in comparison to conventional production is the approach to soil and soil fertility, as is expressed in the regulations on permitted fertilizers and soil amendments. Vegetable crops are characterized by high nutrient contents and high production levels and consequently require high inputs of nutrients, mainly nitrogen and potassium. Furthermore, the cropping period of most vegetable crops is rather short in comparison to arable crops. The current fertilization strategy in practice is characterized by a base dressing of animal manure or compost, and top dressings that are applied throughout the growing season, using a variety of additional fertilizers like keratins (feather-, horn- and hair meal) or...

Biopores have been shown to be enriched with plant available nutrients as compared to the surrounding bulk soil and therefore are considered hot spots for the nutrient acquisition especially in the otherwise nutrient-poor subsoil. As a result of colonization of biopores by earthworms, pore walls are enriched with nutrients. In this study, a first attempt was made to assess the influence of earthworm abundance on both structural pore wall characteristics as assessed with in situ endoscopy and on pore wall C and N contents. Higher earthworm density resulted in higher N contents and significantly higher C contents in biopore walls as compared to the surrounding bulk soil, regardless whether they showed visible earthworm coatings.

Quantitative sector models are an essential tool to forecast the sector-wide economic effects of agricultural policies. However, to cover ecological effects with economic sector models is still a methodological challenge. This poster describes a promising approach, which is currently implemented at the Research Institute of Organic Agriculture (FiBL) to meet this challenge.  CH-FARMIS is a sector consistent farm group model, which is able to forecast economic impacts of policies on farm, regional and sector-level. In a flexible way, CH-FARMIS is able to split up the farm sector in farm groups according to various characteristics (region, farming system, farm type, etc.).

Chicory Grows Roots Below 3 m Is That Beneficial under Water Stress?
Provedor de dados: 21
Autores: Rasmussen, Camilla Ruø; Dresbøll, Dorte Bodin; Thorup-Kristensen, Kristian.
Introduction  Water scarcity is a major limitation to crop production worldwide. Deep-rooted crops can potentially allow exploitation of water that more shallow rooted crops cannot access. Several agricultural crops grow roots of several meters depth within a growing season, and thereby get access to water originating from wet season surplus precipitation stored in the soil. The aim of this study was to test the hypotheses 1) that chicory roots can grow below 3 m within a growing season and 2) that chicory shifts its water uptake downwards when the top soil dries out.    Materials and Methods  Chicory (Cichorium intybus L. cv Chicoree Zoom F1) was grown in 4 m tall rhizotrons in monoculture under dry or wet conditions and intercropped with either ryegrass...

A century ago, China’s sustainable agricultural practices were documented and praised by US Professor of Agriculture, Franklin King, for the successful stewardship of agricultural land over four millennia. Over the past decade, Australia and China have converted more land to organic agriculture than any other of the 160 countries reporting organic agriculture statistics (for Australia, 4.3 m newly converted hectares, and for China, 1.8 m hectares). Australia accounts for about a third of the world’s certified organic agriculture hectares. China’s ‘economic miracle’ has been at the great cost of environmental degradation. There is a role for the development of organic agriculture in China to help achieve a clean green future. Added to this, consumers want...

Carbon offset programmes are creating a new breed of forester. These are retail carbon offsetters who respond to opportunities to offset the carbon footprint of their lifestyle, for example travel, by paying for tree planting. This new cohort of de facto foresters act out of their green values and/or ecological awareness. However since modern silviculture is chemically based, the obverse of their carbon offsetting, is pesticide onsetting - consequently their “solution” is at best dirty green. Forestry standards, FSC, PEFC and SFI, are all very weak standards and allow pesticides and fertilizers. IFOAM previously rejected the adoption of an Organic Forestry Standard. Nevertheless, two organic certifiers have such standards: Debio and Naturland. The entry of...

Climate effects of recycled fertilizers and biochar: emissions of nitrous oxide, methane and ammonia in a field experiment
Provedor de dados: 21
Autores: Norah, Efosa; Krause, Hans-Martin; Bünemann, Else K.; Hüppi, Roman; Häni, Christoph; Six, Johan.
Background  Nitrogen (N) fertilizers are essential for crop production. Farmyard manure and slurry traditionally constitute about half of the total N inputs into crop production in Switzerland. Recycled fertilizers such as biogas slurry, liquid digestates and compost enable simultaneous energy production and closing of nutrient cycles. There is evidence that recycled fertilizers can help to increase N use efficiencies and to improve N supply in organic farming. Biochar amendment has shown a potential to mitigate soil greenhouse gas (GHG) emissions, in particular nitrous oxide (N2O) emissions. Here, we combine one of the liquid recycled fertilizer treatments with biochar. In a 2.5-years on-farm experiment, we quantify GHG emissions and further gaseous...

Closing nutrient cycles in Dutch organic farming: an explorative scenario study of agronomic consequences
Provedor de dados: 21
Autores: van de Ven, Gerrie; Bos, Jules.
Given the principles of organic agriculture, nutrient cycling in Dutch organic farming can be characterised as imperfect, mainly because of large imports of nutrients from conventional agriculture and from abroad. Recently, research has been initiated into the perspectives for better closing nutrient cycles by intensifying the exchange of (by-)products between organic farming sectors. The linear programming model was developed to quantify under different scenarios the agronomic consequences of further closing nutrient cycles in terms of changes in land use and exchange of (by-)products.   Better closing of nutrient cycles requires an increase in the proportion of Dutch feed ingredients in animal diets, an increase in the proportion of feed and leguminous...

Clover content and yield of swards on organic farms - maintenance and estimation
Provedor de dados: 21
Autores: Nykänen, A.; Leinonen, P.; Väisänen, J.
Grassland production based on legumes is an essential part of the productivity and economy of the organic farming systems. The clover content is an important factor in organic grassland management to optimize the yield, feed value and pre-crop effect of ley.    The ley yield and clover content of one-, two- and three-year-old leys were determined on eight organic farms in 1998. Two-year-old leys produced the highest (6500 kg/ha dm) and three-year-old leys (4900 kg/ha dm) the lowest yields, with no significant differences between one- and two-year-old leys. The clover content (20-80 % of dm) diminished to the same extent as the yields.     Because the ley samples from the organic farms gave strong evidence of decreasing yield level and clover content in the...

Clover fatigue - a reason for precaution in organic farming?
Provedor de dados: 21
Autores: Serikstad, Grete Lene; de Boer, A.; Magnusson, C.
Different species of fungi and nematodes cause clover fatigue. The literature review shows that there is a lack of knowledge about the status of clover fatigue in Norway. Samples from fields with clover/grass ley on organic farms in Norway demonstrated the presence of plant parasitic nematodes (Serikstad and De Boer 2013).   High densities of fungi and nematodes can impair the growth of legumes. Intensive use of clover in organic farming systems and a warmer climate are factors that indicate a need for attention to increased occurrence of diseases and pests in clover (Brandsæter et al. 2006). Problems with growing legumes will influence the nitrogen supply and economy in organic farming negatively.

Development of organic plant breeding and seed production will have a valuable impact on organic plant production. Breeding of plant material adapted for organic agriculture is crucial in order to cope with stresses such as climate change, weeds and seed borne diseases. Conventional varieties may not meet the specific needs of organic agriculture. The use of plant material adapted to conditions of organic agriculture will have a positive effect on the productivity and sustainability of organic crop production.

Cocoa agroforestry a bridge for sustainable organic cocoa production
Provedor de dados: 21
Autores: Nunoo, Isaac; Owusu, Victor; Darko Obiri, Beatrice.
In Ghana cocoa constitute about 85 percent of the foreign export earnings from agriculture and also the main source of the wealth to over 800,000 people of the forest regions. Cocoa naturally requires shade which offers farmers agronomic, economic, cultural and ecological benefits.   The promotion and adoption of hybrid cocoa varieties is causing a drift from shaded cocoa to the no shade. The study evaluated the impact shade levels had on the yield of cocoa under the different cocoa agroforestry systems in Ghana. Research data were collected from 200 cocoa farmers in the Sefwi Wiawso district by means of multistage sampling technique through household structured interviews and focus group discussions. Both descriptive statistics and yield curve model were...

Cocoa agroforestry systems vs. monocultures under conventional and organic management - results from tropical Bolivia
Provedor de dados: 21
Autores: Andres, Christian; Milz, Joachim; Seidel, Renate; Trujillo, German; Alcon, Freddy; Weibel, Franco; Schneider, Monika.
Cocoa is one of the most important export commodities for many developing countries and provides income for millions of smallholders. The expansion of cocoa production has resulted in habitat destruction, biodiversity loss, and soil degradation. The prevalent cocoa production systems worldwide are conventional monoculture full sun systems. Agroforestry systems are argued to be a viable strategy for sustainable cocoa production. However, data-based information on advantages and limitations of different cocoa production systems is limited. Pairwise comparisons on the long-term performance of cocoa monocultures and agroforestry systems under conventional and organic management are inexistent.  FiBL is pioneering to fill this knowledge gap with a unique...

Cocoa is a crucial export commodity for many developing countries and provides income for millions of smallholders. However, cocoa cultivation has resulted in habitat destruction, biodiversity loss and soil degradation. While much of the world’s cocoa is produced in arguably unsustainable full-sun monoculture systems, shaded agroforestry systems may be an alternative for sustainable cocoa production. However, data-based information on advantages and limitations of different cocoa production systems are limited and pairwise comparisons on the long-term performance of cocoa monocultures and agroforestry systems under conventional and organic management are literally inexistent.

Cocoa Yield in Bolivian On-Farm Trials 2010-2013 – Monitoring Outstanding Farmers and Comparing Clones and Sites
Provedor de dados: 21
Autores: Andres, Christian; Perez, Eucebio; Alcon, Freddy; Choque, Romero; Trujillo, German; Milz, Joachim; Schneider, Monika.
Cocoa (Theobroma cacao L.) trees have a lifespan of up to 100 years in their natural environment, the lower strata of tropical alluvial forests. Sustainability of global cocoa production is at stake due to the deterioration of soil fertility, high losses due to pests and diseases (P&amp;D) and old tree stock. Producing cocoa in shaded, low input agroforestry systems offers a potential solution for achieving long-term productivity and sustainability. However, shade-tolerant cocoa clones are needed which are productive and resistant to P&amp;D, as well as meeting the quality standards requested by the industry. In Bolivia, the cocoa mirid (Monalonion dissimulatum) and the novel disease Frosty Pod Rot (“Monilia” Moniliophthora roreri) are among the most...

Codigestion of manure and organic waste at centralized biogas plants: Process imbalances and limitations
Provedor de dados: 21
Autores: Nielsen, Henrik Bangsø; Angelidaki, Irini.
The present study focuses on process inhibitions in Danish centralized biogas plants. Collection of data from the plants and a number of interviews showed that inhibitions occur frequently. High concentrations of ammonia, long chain fatty acids or other inhibitory compounds, and foaming in prestorage tanks are well known causes of inhibition. These problems mainly occurs due to: 1) inadequate knowledge about the waste composition and 2) its degradation characteristics, 3) inadequate process surveillance especially with regard to volatile fatty acids and 4) insufficient pre-storage capacity causing inexpedient mixing of the different waste products in the pre-storage tanks.

Co-existence in maize supply chains in Spain and Switzerland
Provedor de dados: 21
Autores: Oehen, Bernadette; Costa-Font, Montserrat; Morgner, Marion; Gil, José  M.; Stolze, Matthias.
The debate about co-existence usually focuses on the situation of neighbouring farms. Organic producers take the position that co-existence affects the whole supply chain. Therefore, this paper compares the maize grain supply chains in Switzerland and Spain in order to identify which factors influence the segregation of genetically modified (GM) maize from non-GM maize, and discusses how organic production copes with the challenge of GM maize. Considerable differences exist between Spain and Switzerland with regard to grain maize as a component of animal feed. In Spain, where GM maize is grown, it is the feed industry that defines standards in the supply chains. Since the trading co-operatives are unable to supply GM-free maize, independent and separate...

Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards.  Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds.   Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence in the supply chain of propagated seed. With the increasing area of GM-crop production as well as in the number of crops in which GM-varieties are available the need for guidelines to ensure coexistence are becoming increasingly essential....

Collembola’s role in regulating mass fluxes in soil and the effects of contrasting life histories
Provedor de dados: 21
Autores: Larsen, Thomas; Krogh, Paul Henning; Magid, Jakob; Hobbie, Erik; Marc, Ventura.
The study determined metabolic rates and elemental pools for two Collembola species with contrasting life histories. The fittest of the two species, P. minuta, excreted the equivalent of 10–12% of the elemental body content per day, and P. armata 7–10%. Most elements are lost to excretion (CO2 and N-waste). These figures in combination with stoichiometry and life histories indicate that the cost of P. minuta’s better fitness is a requirement for a higher quality diet than P. armata. The data produced in this study can be used to estimate the collembolan contribution to C and N fluxes in the soil.

Coloured mulch as a weed control technology and yield booster for summer savory
Provedor de dados: 21
Autores: Walker, R L; Svoboda, K; Booth, E J; Walker, K C.
An investigation into the effect of coloured mulch technology as a technique to control weeds when growing the essential oil plant, summer savory (Satureja hortensis) was made. As well as weed control, the effects on the production of crop biomass and essential oil content and quality were also considered. The mulch treatments produced significantly more biomass than either of the control treatments (which used no mulch either with or without herbicide). The white mulch treatment produced the greatest biomass, closely followed by the red mulch treatment. The blue mulch treatment was third in ranking, although not significantly greater than the black mulch. Estimates of the quantity of essential oil produced by each treatment followed a similar trend to...

Combination of different methods for direct control of Vicia hirsuta in winter wheat
Provedor de dados: 21
Autores: Lukashyk, Pavel; Koepke, Ulrich.
Combinations of three different direct methods for controlling Vicia hirsuta (kainite application, flame weeding and harrowing) were investigated in field experiments. They were based on different strategies at early growth stages of V. hirsuta and standardised harrowing at late growth stages. The highest efficacy of kainite application and flame weeding was achieved at the one leaf stage of V. hirsuta. Winter wheat regeneration from damage caused by both kainite and thermal control was satisfactory when treatments were applied at early growth stages (GS 23). Vicia hirsuta plants that survived kainite application or flame weeding were successfully controlled by repeated harrowing at later crop growth stages; crop growth was not affected. Seed production of...

There is a lack of results on the advantages and limitations of combining different crop diversification strategies both in time and space, which makes it difficult for famers and advisers to find relevant information for the transition towards more diversified cropping systems. A network of ten field experiments (diverIMPACTS project) was built across seven European countries, covering a range of pedo-climatic conditions and different farming systems: arable and vegetable systems under both conventional and organic management. Each field experiment tests one or several diversified cropping systems, which combine  three  diversification strategies with low input practices. These diversified cropping systems are compared to reference systems, which are less...

Autores: Sugimoto, Hideki; Takuya, Araki; Masahiro, Morokuma; Hossain, Shaikh Tanveer.
The combined application of oil cake and rice bran into the soil surface was found useful for weed control in our previous pot study. The present study was undertaken to evaluate the performance of white clover (Trifolium repens L.) while incorporated in the paddy field and effects of combined fertilizer on weed control and rice yield.  A plot was divided into two parts i.e. white clover incorporated and not incorporated. The nitrogen content of the incorporated white clover was 12.5 gm-2. Chemical fertilizer and combined fertilizer plots were compared with non-fertilizer conditions. The mixed ratio of combined fertilizer was oil cake 1.35 and rice bran 1.0. Combined fertilizer was applied to the soil surface, and chemical fertilizer was mixed in the soil....

Combined energy and feed production by thermophilic digestion of manure, grass and maize silage
Provedor de dados: 21
Autores: Falconi, S; Møller, Henrik B.; Ward, A.
By anaerobic digestion of crops and manure it is possible to produce energy, organic fertilizers and good quality feed with a high content of amino acids. This can be one solution to solve the problems concerning the competition between food and energy crops. At the same time, the production of energy by anaerobic digestion limits the use of fossil fuels.   In this study the productive performance of maize and grass silage in terms of biogas and CH4 yield was analysed. The variation of amino acids content of these crops and of cattle and pig manure by anaerobic digestion was studied also.

Combined production of broilers and fruits
Provedor de dados: 21
Autores: Lindhard Pedersen, H.; Olsen, A.; Pedersen, B.; Korsgaard, M.; Horsted, K.
Combined production of broilers and fruit trees is a subject often discussed in organic fruit  production in Denmark. Very little research has been carried out on this type of production  system. In organic production in Denmark, nearly no pesticides are allowed, so the need  for alternative pest control is large. Apple sawfly (Hoplocampa testudinea) and pear midge  (Contarinia pyrivora) cause big crop losses in apples and pears respectively, in unsprayed  organic fruit production. Both insects infest fruitlets and cause these to drop prematurely  after which the pests pupate in the topsoil. In the present experiment a research orchard  with the varieties ‘Discovery’ and ‘Conference’ were used as outdoor area for broilers to  minimise the population of...

Combining Ethological Thinking and Epidemiological Knowledge to Enhance the Naturalness of Organic Livestock Systems
Provedor de dados: 21
Autores: Vaarst, M.; Roderick, S.; Lund, V.; Lockeretz, W.
Organic livestock farming places strong emphasis on conditions that allow animals to exhibit behavioural needs. This involves the provision of a natural environment and, in particular, outdoor conditions and a reliance on natural forages. Such environments also allow animals to be effectively integrated into crop production. However, there are potential disease risks associated with these conditions, with control options being partly limited by restrictions on chemoprophylactic measures. Examples from dairy and poultry production demonstrate how a basic understanding of ethology and a knowledge of disease epidemiology can enhance the welfare of animals whilst satisfying the ecological objectives of organic farming. Existing epidemiological models and...

Provedor de dados: 21
Autores: Wiedenhoeft, Mary; Porter, Paul; Dehaan, Robert; Francis, Charles.
To understand multiple dimensions and connections in today’s complex farming systems, it is essential to move beyond the narrow disciplinary focus found in most university agriculture courses and learn from farmers who are intimately integrated with farm decisions. In many ways, the classical agriculture department is a human construct developed for our convenience, and as such it scarcely represents an ecological structure operating on farms. To adequately delve into the mechanisms of crop/weed, crop/animal, product/market, and myriad other interactions involved in agriculture, it is essential that we draw on methods from the biophysical and social sciences to help us understand the human activity system that is farming. For more than a decade, we have...

Combining Luhmann and Actor-Network Theory to see Farm Enterprises as Self-organizing Systems
Provedor de dados: 21
Autores: Noe, Egon; Alrøe, Hugo Fjelsted.
From a rural, sociological point of view no social theories have so far been able to grasp the ontological complexity and special character of a farm enterprise as an entity in a really satisfying way. The contention of this paper is that a combination of Luhmann’s theory of social systems and actor-network theory (ANT) of Latour, Callon, and Law offers a new and radical framework for understanding a farm as a self-organizing, heterogeneous system.     Luhmann’s theory offers an approach to understand a farm as a self-organizing system (operating in meaning) that must produce and reproduce itself through demarcation from the surrounding world by selection of meaning. The meaning of the system is expressed through the goals, values, and the logic of the...

Combining on-farm, participatory research methodologies with modelling in order to create a regionally based organic agriculture in Holland
Provedor de dados: 21
Autores: Prins, Udo; de Wit, Jan; Nauta, Wytze.
Like conventional farming, organic agriculture in the Netherlands is highly specialized. Both livestock and arable farmers have optimised production independent of each other which has led to a high use of external inputs from conventional agriculture (manure and other fertilisers and straw) and feedstuffs (mainly concentrate feed) from abroad. This situation conflicts with important principles of organic agriculture such as a balance between livestock and arable farming, closing nutrient cycles and regionally based production. In an attempt to find solutions for this dilemma, the Louis Bolk Institute (LBI) started with a series of projects called “Partner Farms” in which the LBI cooperated closely with leading edge farmers (Wit et al, 2003). In these...

Autores: Baiamonte, I; Moneta, E; Raffo, A; D'Aloise, A; Nardo, N; Kelderer, M; Lardschneider, E; Paoletti, F.
In the organic production only organic fertilizers can be used to supply the soil with nitrogen. The mineralization of these products is slow causing a problem with the nitrogen supply when the demands of the plants is high.  Italy is the main producer of organic apples in Europe (about 42,000 MT on 115,000 MT in 2006). More then 60% of  the organic apples produced in Italy are grown in Alto Adige region (North-East of Italy). In this region problems with nitrogen supply to apple plants in spring are common. In  spring the demand of nitrogen of the apple trees in Alto Adige is high, but the weather conditions are often bad and the temperature of the soil is slow. In these conditions the mineralization of the organic fertilizers starts slowly, the trees own...

Common bunt resistant wheat composite cross populations
Provedor de dados: 21
Autores: Steffan, Philipp; Borgen, Anders; Backes, Gunter; Rasmussen, Søren K.
Utilising diverse populations instead of single line varieties is expected to lead to a number of advantages in cereal production. These include reduced epidemics of plant diseases, improved weed competition and better exploitation of soil nutrients, resulting in improved yield stability. However, a number of challenges must be met before diverse wheat populations can be introduced into commercial wheat production: one of these is the development of breeding technologies based on mass selection which enable breeders and farmers to improve specific traits in populations and maintain diversity at the same time.  BIOBREED is a project started in Denmark in 2011 to meet these challenges for wheat population breeding. The project is focusing on the development...

They say that sustainable development has been around for about 20 years and not very much progress has been achieved. However, this view may refer to difficulties in identifying sustainable developments in everyday business activities without particularly visible publicity. Currently, new serious activity towards sustainable food systems, starting from retailing, processing industries and farmers as well as other food system actors seem to strive to connect the supply chains for sustainable food. This paper makes use of the notion of ‘social rhizomes’ structured as different networks to identify sustainable developments in actors’ lived experience. Furthermore, the notion of connectivity, as the ability to activate heterogenous ideas, persons, materials...

Communicating trust? The role of Facebook for establishing producer-consumer relations
Provedor de dados: 21
Autores: Schermer, Markus; Furtschegger, Christoph.
Values-based supply chains depend highly on consumer trust. Consumers expect that they can be trusted to (for instance) comply with certain production standards, contribute protecting the environment, secure that producers receive a fair price or that ways of transportation are shortened and an added-value for the region is achieved. Particularly in direct marketing, with (at least potentially) interpersonal exchange relationships between producers and consumers, trust in these attributes is highly developed and distinctively strong. However, while values-based food systems like organic food still experience an ongoing and unbroken popularity, they enter increasingly larger and extended market structures in which the direct contact between producers and...

Communication of ethical values in organic farming
Provedor de dados: 21
Autores: Zander, Katrin; Hamm, Ulrich.
Due to globalisation and growing anonymity of trade with organic products, farmers in Europe are under pressure to lower their production standards in order to keep up with world-wide competition. On the other hand consumers increasingly criticise food products which were produced under unsatisfactory social and environmental conditions. A literature review indicates that consumers are willing to pay an additional premium for ethical values in organic production regarding social, environmental and economic concerns. This creates possibilities to differentiate from the organic mass markets by providing and communicating ethical values. So far, not much is known about which ethical values and arguments are comprehensible and important to organic consumers...

Community financing in the German organic food sector: a key for sustainable food systems?
Provedor de dados: 21
Autores: Behrendt, Gerlinde; Peter, Sarah; Sterly, Simone; Häring, Anna Maria.
The rise of socially responsible and impact investing funds provides evidence for an increased interest private investors have in combining their financial and ethical concerns. At the same time, citizens increasingly engage in food networks and take on a vital role in the governance of agri-food systems. These developments might benefit farms and firms which are committed to sustainable food and seek funding. Through different community financing models, they can involve citizens who aim to support the development of a more sustainable food system.  This contribution presents case study evidence on community financing in the German organic food sector and discusses the role it can play in food system transformation.

Autores: Friis Pedersen, Susanne.
Norway covers an abundant wilderness, only three % of the land are cultivated. The last ten years the eagerness to form and join Community supported Agriculture, CSA, has boomed. The initiative is supported by NGOs and authorities. A literature survey shows what makes the Norwegian experience special and what is common with other urban efforts. The survey focuses on sustainability in household and lifestyle. Hypothesis was that organic agriculture is a way for sustainability and furthermore a goal set by authorities and peoples organizations. Most important conclusions where that CSA indeed makes a step forward to sustainability even though some questions and conflicts of interests may appear.

The over-simplification of modern intensive agro-ecosystems in terms of cultivated biodiversity had dramatically increased their vulnerability to stresses and perturbations. In order to create and use a higher specific and genetic diversity several community management seed systems (or “Seed Houses”) are being currently set up in France. In this country where most farmers are used to buying commercial seeds, these initiatives are considered innovative. They also raise several issues such as: how to obtain, improve and conserve adapted plant genetic resources? How farmers’ communities can organise themselves to produce and exchange seeds amongst their members? Which procedures, which quality thresholds, which skills and which tools must be developed?

Regarding stocking rate levels, no significant differences were observed among groups. By contrast, significant differences among the three types of farms regarding racial structure (p &lt;0.05). Similarly, significant differences were found (p &lt;0.1) in relation to farm's area, cattle's reproductive management and performance.    The study highlights the similarity between conventional and organic cattle production in Extremadura. This fact could allow a smooth transition of conventional farms to the organic production model.

Comparative analysis of conventional and organic farming systems: Diversity and abundance of farmland birds
Provedor de dados: 21
Autores: Neumann, Helge; Loges, Ralf; Taube, Friedhelm.
A comparative study on the abundance of breeding birds and wintering birds was carried out over the period 2005-2007 in conventionally and organically managed arable fields in Northern Germany. Birds were surveyed on 40 (breeding season) and 35 (non-breeding season) pairs of fields (conventional/organic), which were selected with regard to similar field sizes, comparable boundary structures (hedges, shrubs) and representative crop rotations. Averaged over three years of investigation, skylarks (Alauda arvensis) and, less distinct, pheasants (Phasianus colchicus) occurred more often on organic fields. In contrast, yellow wagtails (Motacilla flava) showed higher abundances on conventional fields in one year. The diversity of farmland bird species was not...

Comparative analysis of conventional and organic farming systems: Nitrogen surpluses and nitrogen losses
Provedor de dados: 21
Autores: Kelm, Dr. Michael; Loges, Dr. Ralf; Taube, Prof. Dr. Friedhelm.
Nutrient management is a key factor for both economic viability and environmental performance of farming systems. On 32 representative conventional and organic farms in Northern Germany, nutrient management was analyzed in the interdisciplinary monitoring project “COMPASS”. Organic farms had significantly lower nitrogen (N) surpluses compared with conventional farms. The majority of organic farms had very low or even negative N surpluses, indicating insufficient N supply in the cropping system. Nitrogen leaching, however, was too high in many cases on both conventional and organic farms. Strategies for a more targeted nutrient supply in organic farming need to be developed and implemented.

Comparative analysis of the impacts of marketing instruments on the organic market in Austria, the United Kingdom and Germany
Provedor de dados: 21
Autores: Zenner, S.; Foster, C.; Padel, S.; Wirthgen, B.
Conclusions:    This paper provides a comparative analysis of the impacts of the marketing instruments: The price-level can be identified as an important factor for further development. To promote sustained consumer demand, the premium price-level should be closer to the conventional price, although consumers are willing to pay some premium. Organic produce is associated with healthy food, which may appeal to consumers interested in healthy nutrition. Nevertheless, producers, processors and retailers of organic food should bear in mind general trends in food consumption and create organic food with lifestyle-oriented design. In future, supermarkets will become the main retail outlets for organic produce. In order to compete with larger, mainstream...

Comparative environmental assessment of three systems for organic pig production in Denmark
Provedor de dados: 21
Autores: Halberg, Niels; Hermansen, John E.; Kristensen, Ib Sillebak; Eriksen, Jørgen; Tvedegaard, Niels.
Organic pig production has emerged as an alternative to the intensive conventional pig production in Europe with the animals confined indoors and often an imbalance between livestock and land for feed production and manure utilisation. The organic systems aim at improving animal welfare by supporting the pig’s natural behaviour (Hermansen et al., 2003), and improving soil fertility by better linking crop and livestock production from an agro-ecological point of view.    The differences between organic and conventional pig production is more fundamental than for example differences between dairy production systems, which may be why the share of pig herds within the organic holdings is considerably lower than the percentage of pig herds in conventional...

Comparing conventional and improved organic vegetable  rotations, yields and nitrogen husbandry
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian; Kristensen, Hanne L.
During 2005 to 2009 three approaches to organic vegetable rotations were compared to a conventional rotation in an interdisciplinary project. The organic rotations differed in their reliance on animal manure vs. cover crops and intercrops, but the rotation of main vegetable and cereal crops were identical in the four rotations. One organic rotation (O1) relied on import of manure for supply of nutrients, in another (O2) cover crops were used to replace most of the manure import, and in (O3) also intercrops were grown to improve natural pest regulation. The yearly import   of nitrogen were on average 149, 94, 28, and 28 kg N.ha-1 in C, O1, O2, and O3 respectively. On average the yield in the O1 system was 83% of the yield in the conventional system.

This study was conducted to explore organic and conventional dairy farmers' perceptions of risk and risk management, and to examine relationships between farm and farmer characteristics, risk perceptions, and strategies. The data originate from a survey of conventional (n=363) and organic (n=162) dairy farmers in Norway. Organic farmers had the least risk averse perceptions. Institutional and production risks were perceived as primary sources of risk, with farm support payments at the top. Compared to their conventional colleagues, organic farmers gave more weight to institutional factors related to their production systems. Conventional farmers were more concerned about costs of purchased inputs and animal welfare policy. Organic and conventional farmers'...

Comparing two models of the diurnal temperature cycle for simulations of crop and pest phenology under climate change
Provedor de dados: 21
Autores: Felber, Raphael; Fuhrer, Jürg; Stöckli, Sibylle; Calanca, Pierluigi.
Air temperature is the most important determinant of crop and pest phenology. Developmental rates of organisms are thus usually modelled as a function of growing degree-days. These can be evaluated based on either daily or hourly temperatures. However, as climate model do not provide reliable information at high temporal resolution, statistical or empirical models are needed to generate hourly temperature data for assessing crop and pest phenology under climate change.  We present the comparison of two approaches for generating hourly temperatures from daily values of the minimum (Tmin) and maximum (Tmax) temperature. The statistical downscaling approach proposed by Hirschi et al. (2012) uses a nearest neighbour re-sampling procedure to prescribe realistic...

Introduction:  During the last years, concern has increased concerning animal welfare at the farm level. The Associations of Organic Agriculture have elaborated minimum requirements regarding animal welfare. The aim of the study was to compare the welfare status on conventional and organic dairy farms.      Conclusions:  Concerning sample used (straw based loose housing systems), organic farms on average showed a better welfare status than conventional farms. This has also been demonstrated in other studies (for a review see Hörning, 1998). Mean points achieved in single criteria show deficiencies and therefore potential for improvements. The respective scoring systems seem to be suitable for an on-farm assessment of housing conditions and thus to...

Comparison of Canopy Openness in Different Cocoa (Theobroma  cacao) Production Systems in Alto Beni, Bolivia
Provedor de dados: 21
Autores: Niether, Wiebke; Maldonado, Carla; Silva, Erika; Schneider, Monika; Gerold, Gerhard.
Cocoa (Theobroma cacao L.) grows naturally as an understory tree in tropical forests and produces well under shaded and non-shaded conditions. It is cultivated by small scale farmers in South America under various conditions, ranging from monocultures to different kinds of agroforestry systems. While in monocultures it is exposed to direct sunlight, one or various tree species shade the cocoa in agroforestry systems. Also organic cocoa cultivation is becoming more and more popular due to premium prices and increasing ecological consciousness. In Alto Beni, Bolivia, the Research Institute of Organic Agriculture (FiBL) and local partners have established a long-term field trial to compare cocoa production systems.

Comparison of European hare (Lepus europaeus) population densities between an eco-farm and a conventional farm
Provedor de dados: 21
Autores: Rühe, Ferdinand; Felix, Jacqueline; Rahmann, Gerold; Ulverich, Jürgen; Weißmann, Friedrich.
European hare populations have not recovered from their shrinking over the past fifty years in Germany. Most hare habitas are agricultural regions which are farmed according to conventional farming standard. Organic farming is characterized by waiving of pesticides, growth regulators and arificial manure, by longer crop rotations and by wider seed seed-row spacings in some cereal crops. Thus, positive effects of eco-farming on hare populations in agricultural landscape may be assumed. However, eco-farming has not been studied in this regard up to now.

Onions are known to contain high levels of flavonoids and a comparison of the efficiency, reproducibility and detection limits of various extraction methods has been made in order to develop fast and reliable analytical methods for analysis of flavonoids in onions.  Conventional and classical methods are time- and solvent-consuming and the presence of light and oxygen during sample preparation facilitate degradation reactions. Thus, classical methods were compared with microwave (irradiation) extraction, ultrasonic liquid extraction and accelerated solvent extraction.

Autores: Legzdina, L.; Kokare, A.; Beinarovica, I.; Lammerts van Bueren, Edith T.
While breeding for organic farming it is necessary to identify the most appropriate growing  conditions in which to perform the selection process. Soil fertility, crop management, yield level  and other factors may vary very much between each organic farm, and between organic farms and  research institutions where the selection is usually performed. Since plant breeding requires  considerable input of resources and the market for organic varieties is limited, it is essential to find  the most appropriate selection conditions that will provide acceptable varieties for organic farms.  Spring barley breeding lines selected from two cross combinations (Primus/Idumeja and  Anni/Dziugiai) at two distinctive organic and two conventional locations were used in the...

This report was presented at the UK Organic Research 2002 Conference. Recent research confirms that the decision to convert is now highly influenced by financial incentives arising from EU regulations but the exact mix of incentives depends on prevailing government policies and access to premium markets so that the organic sector in most countries is now referred to as either government-led or market-driven. The objective of the paper is to compare development of the sector along these two polarities but set within the context of "common elements of interest" within new agrifood methodologies: time, space, power, and meaning (Cooke, Uranga and Etxebarria 1998; Morgan and Murdoch 2000).

To estimate the cocoa dry bean weight from the fresh weight a standard dry bean factor (DBF) ranging from 32% to 40% is usually applied. This factor, i.e. the relation between the dry bean weight (fermented and dried) and the fresh weight at pod opening, is used by cooperatives and factories that buy the fresh beans of the farmers. However, this factor is subjected to seasonal fluctuations and can be highly influenced by rainfall. Therefore, for instance, higher values are expected during the dry season compared with the rainy season.  The objective of this study was to evaluate the accuracy of the use of a standard fix DBF value compared with the use of actual DBF values periodically collected over the season for assessing the performance of 12 cocoa...

Comparison of Organic and Conventional Beef-Suckler Farms in Germany
Provedor de dados: 21
Autores: Hörning, Prof. Bernhard; Feige, Martina; Dollinger, Julia.
This study aims to compare conventional and organic farms with beef-suckler herds. Addresses were collected mainly by contacting breeding associations and farmers' magazines. 216 questionnaires were evaluated (34.1% of them organic). Beef-suckler production in Germany is an extensive production system (small farms, small herd sizes, high percentage of grassland, low soil points, etc.). 39% of farms had to fulfil special regulations for extensive grassland production and 43% carried out landscape conservation measures. Farmers specialize in beef-suckler production. 60% of them are part-time farmers. Beef production amounts to two thirds of their agricultural income. Most farmers keep only beef cattle on the farms. Other farm animals are kept in small stock...

Comparison of organic and conventional dairy farm economic and environmental performances throughout North West Europe
Provedor de dados: 21
Autores: Grignard, A.; Stilmant, D.; Oenema, J; Tirard, S.; Debruyne, L.; Hennart, S.; Jamar, D.; Boonen, J.
From an environmental point of view, organic farming (OF) systems have been identified as beneficial thanks to a system allowing fewer losses of nitrogen (N) per ha and lower green house gases (GHG) emissions per ha and per ton of milk (TM). From an economic point of view, milk coming from these OF systems is sold at a higher prize. However, incomes provided by both systems are similar (for similar amount of milk produced). This may be explained by higher input costs per unit of product for OF systems and by more incomes coming from sold crops for conventional farming (CF) systems.    Therefore, on the one hand CF systems may improve their environmental performances by reducing the amount of inputs brought into the system, for example through a better...

Sustainable floor management has played an important role in viticulture recently. Intensive agricultural practices of past decades - like mechanical cultivation on steep slope vineyards - endanger the vineyards. Suboptimal inter-row and undervine floor management, especially coupled with extreme weather conditions can lead to heavy soil degradation. In addition, because of climate change we anticipate heavier rainstorms, which can accelerate degradation of the soil. In Hungarian viticulture, preservation of soil moisture is extremely important because of the low amount of annual precipitation (sometimes less than 500 mm per year) and evapotranspiration from June to August is typically higher than precipitation (Bauer et al., 2004). Therefore, the use of...

Comparison of the Nutritive Quality of Tomato Fruits from Organic and Conventional Production in Poland
Provedor de dados: 21
Autores: Hallmann, Ewelina; Rembiałkowska, Ewa.
Organic horticulture is generally accepted as friendly to the environment, good for crop quality and also for the consumer’s health. Recent research data has shown that organic crops under organic farming practices contained more bioactive substances such as flavones, vitamin C, carotenoids; they also contain less pesticides residues, nitrates and nitrites. Five tomato cultivars: four large – fruit (Rumba, Juhas, Kmicic, Gigant) and one cherry cultivar (Koralik) were selected for study. The organic tomato fruits contained more dry matter, total and reducing sugars, vitamin C, total flavones and beta-carotene, but less lycopene in comparison to conventionally grown tomatoes.

Comparison of two different dairy cow types in an organic, low input milk production system under Alpine conditions
Provedor de dados: 21
Autores: Horn, Marco; Steinwidder, Andreas; Podstatzky, Leopold; Gasteiner, Johann; Zollitsch, Werner.
The core task of sustainable milk production is the conversion of forage into milk, dairy products and, as a by-product, into meat. In Europe and North America, for decades dairy cows were selected for a high genetic merit for milk production under high input farming conditions. It is therefore questionable whether these "high input genotypes" are suitable for forage-based, organic farming systems. The objective of this study was to compare two cow types concerning their suitability for an Alpine organic, low input dairy production system. The cow types used were conventional Brown Swiss (BS) on the one hand and a specific strain of Holstein Friesian (HFL), selected for lifetime performance, on the other. Both cow types were managed within one herd in an...

Autores: Kaffka, Stephen; Bryant, Dennis; Denison, Ford.
Yield differences and trends, organic matter accumulation, and the loss of nutrients to deeper soil horizons are discussed using data from organic and conventional maize/tomato cropping systems from the Long Term Research on Agricultural Systems Project (LTRAS) at the University of California, Davis.  Compared to the conventional system, higher and increasing yields of tomatoes were observed in organic systems, but lower yields of maize.  Fruit quality, measured as soluble solids, was not significantly different.  Soil organic matter increased in the organic system, but remained stable in the conventional one.  More irrigation water was used in the organic system than in the conventional one due to higher rates of infiltration, but less winter runoff...

COMPATIBILITY OF AUTOMATIC MILKING SYSTEMS WITH ANIMAL WELFARE IN ORGANIC DAIRY FARMING
Provedor de dados: 21
Autores: Bühlen, Franziska; Ivemeyer, Silvia; Krutzinna, Christian; Knierim, Ute.
The distribution of automatic milking systems (AMS) on dairy farms has increased significantly worldwide since the last millennium. For organic farms in Germay, the use of this technique is increasingly interesting, as organic dairy farms often have herd sizes between 50 and 150 cows which suit best for automatic milking systems. The implementation of AMS does not only bring along changes in terms of the milking process, but also affects the entire housing system, management and feeding. AMS is often connected with a restriction of pasturing and indirectly the risk of lame cows may increase.  The aim of this study was to clarify whether the use of AMS is compatible with animal welfare in organic dairy farming, paying particular attention to impacts on...

Compensating damage effects of seed-borne Fusarium culmorum and Microdochium nivale in winter wheat by increased seeding rates
Provedor de dados: 21
Autores: Pinnschmidt, H.O.; Justesen, A.F.
Fusarium culmorum and Microdochium nivale are considered important seed-borne diseases of wheat in Denmark. Their damage effects consist in reducing seed germination and plant emergence which leads to reduced plant density, panicle numbers/area and yield. The aim of this study is to find out whether and to what degree these damage effects can be compensated by increased seeding rates. A trial was therefore conducted in 2004 in which seed lots of three winter wheat varities (Ritmo, Bill and Boston) having various degrees of infection by F. culmorum and Microdochium nivale were sown at various seeding rates. Seed contamination of the two pathogens was determined by counting the number of discoloured roots in the seed batches (Doyer method). Plant emergence...

Autores: Bavec, Franc; Živec, Urška; Grobelnik Mlakar, Silva; Bavec, Martina; Radics, Laszlo.
Intercropped crops represent an important production system in organic farming, especially maize/climbing bean mixture due to its high content of protein in bean seeds for human diet, and producing silage for ruminants. To test this hypothesis, the effects of  maize (Zea mays L.) sown as a sole crop and maize/climbing bean (Phaseolus vulgaris L. cv. Cipro) mixtures on maize plant height, maize leaf area index, bean leaf area index and grain yield were investigated in field experiments on an organic farm following accepted rules of certification. The maize/climbing bean mixture increased maize plant height as well as maize and bean leaf area and reduced maize grain yield in comparison with maize sown as sole crop, but 477.5 kg ha-1seed yield of bean sown in...

Using a competitive crop like oats is essential for integrated management of weed problems.  Oats can compete well with weeds through efficient nutrient uptake, allelopathy and canopy cover shading.  Weeds are suppressed by the crops tillering ability and varieties with good canopy cover.  Some varieties can tolerate weeds better by having both good canopy cover and height.

Beef pasture-based systems of Europe, especially those located in disfavored areas, play a key role in the maintenance of the ecosystems and rural population. However, they suffer from low competitiveness. In this sense, the design of improvement measures is needed. Due to this, this work has two objectives: (1) to assess the competitiveness of the beef pasture-based systems of the Spanish rangelands ('dehesas'); (2) to design improvement measures. For this purpose, a Competitiveness Index (CI) was created on the basis of technical and economic indicators.

The need for competitive crop stands can be regarded as a basic requirement for weed control, potentially reducing the need for direct control measures. One way the crop may suppress weed growth is by the restriction of light through crop shading. As part of the EU-project ²Strategies of weed control in Organic Farming² (WECOF) trials with winter wheat were carried out to evaluate the potential of wheat shading ability as a weed control measure. Factors included were cultivar, row width and drilling direction. Results of the first experimental year are presented.

Complexity and trust – experiences from local Danish Food Communities
Provedor de dados: 21
Autores: Thorsøe, Martin H.; Kjeldsen, Chris.
Generally food consumers in Denmark do not trust the food production and distribution systems and the management of risk related to food consumption has become part of the daily life of many (Halkier &amp; Holm, 2004). This paper explores how relations of trust are formed in two local Danish Food Communities (Fødevarefællesskaber) in Aarhus and Copenhagen. Food Communities are communities of consumers organized around the provision of local fresh vegetables directly from local producers. The Food Communities, together with local farmers, share the responsibilities, normally carried out by other market actors, such as logistics, sale and price formation. The vegetables are sold to the members of the community, at a relatively low price, if they take part in...

Composition of variety mixtures in barley and wheat
Provedor de dados: 21
Autores: Østergård, H.
Breeding within the last 50 years has focused on developing genetic uniform crops/varieties for farmers to be able to produce homogeneous products to be sold. Therefore, especially for selfing crops like wheat and barley where nearly all plants in a field are genetical identical, specific tools have to be applied to ensure genetic diversity. Among these tools is the use of variety mixtures. Principles for composing variety mixtures are to a large extent based on disease resistance characteristics and this is insufficient to predict the performance of the mixtures. Biological principles for interactions between varieties will be of relevance not only to organic farming but also to conventional agriculture where variety mixtures have been used for many years...

Currants (Ribes spp.) are the second largest group of cultivated berries in Europe with  an annual output of fresh berries over 700,000 tons. The major countries of currant  cultivation include Nordic countries, Poland, Germany, France, Russia and the United  Kingdom with different cultivars, growth environments, and cultivating techniques  among these countries. Fruits of currants have been shown to have a wide range of  beneficial effects on human health. The sensory properties and health effects are of  crucial importance for the industrial utilisation of the berries. Genotypes and growth  environments play an important role in modifying the composition of the berries that  directly defines the nutritional and sensory qualities of the fruits.

Autores: Tabrika, Ilyass; Azim, Khalid; Mayad, El Hassan; Zaafrani, Mina.
Each season, a huge amount of crop residues is regenerated by horticultural production. The main type of wastes are tomato stalks, leaves and axillary buds which are subsequently the result of crop operations like trimming and plants trellising and uprooting. The landfilling of corps residues is a serious problem that need to be solved. Therefore, the valorisation of these organic wastes by composting is a simple way for suitable management and the produced compost could be used as an organic amendment to satisfy the crop growth needs and agronomic soil requirements. The aim of the study is to investigate the impact of the mixing proportion of tomatoes residues and sheep manure using an experimental biocomposter of capacity 220 L with passive aeration...

Composting poultry manure by fly larvae (Musca domestica) eliminates Campylobacter jejuni from the manure
Provedor de dados: 21
Autores: Nordentoft, Steen; Hald, Birthe.
Introduction The common house fly, Musca domestica (Md) is an important carrier of zoonotic agents, and Campylobacter jejuni is one that may be transmitted between animals and humans by flies. Colonized animals shed the bacteria in feces where larval stages of Md flies develops. Aim of the present study To monitor fly larvae composting of poultry manure artificially contaminated with C. jejuni, and to investigate a possible transmission route of C. jejuni from the manure through the fly larvae to the adult fly.  Conclusions  The addition of fly larvae both accelerated the degradation of manure and C. jejuni. Pupae or newly hatched flies were not carriers of C. jejuni although larvae were grown in contaminated manure.  Impact  When composting poultry manure...

Computer model for simulating the long-term dynamics of annual weeds
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Holst, Niels.
A simulation model of the population dynamics of annual weeds and how it is affected by crop rotation, cultivation practices and weed control was presented by Rasmussen et al. (2002). The model aims to predict the development of a certain weed species in order to plan crop rotation and cultivation practices to minimise the risk of proliferation. The model does not predict the exact number of weeds expected to be found in a certain year or crop, but rather the general development over a number of years. It included the most important processes of the weed life cycle: seed survival in the soil, seed placement in soil after tillage, seed germination depending on soil depth, time of year and tillage and weed physiological development. The component describing...

Concepts and Actors in Organic Livestock Husbandry in Bolivia
Provedor de dados: 21
Autores: Kneer, Oliver; Siegmund-Schultze, M.; Delgado, F.; Valle-Zárate, A.
Traditional smallholder livestock production is expected to correspond widely with principles of organic livestock farming. Though, the real magnitude of livestock under organic and alike management is unknown. From stakeholder analysis and structured interviews with key persons in Bolivia it is deduced that similarities are widely given, whereas it is questioned whether a formal individual certification approach for livestock products will match the farmer interests and consumer demands.

This study presents a new approach to model the biophysical potentials for increased biomass harvest in Denmark, and a multi-criteria sustainability assessment of the socio-economic and environmental effects of different scenarios for such increased production and new biobased economy in rural landscapes. Thereby the results serve as input to the ongoing productivism – post-productivism debate related to rural spaces in Europe.  Empirical results from a case study of large scale conversion to biorefenery technologies, aiming to increase the total Danish harvest of biomass by 10 million tonnes via the conversion to new types of crop production and land management, is used as an example, and will be related to the common conceptual model presented by the...

Conference pears; work on system changes to enable better scab  control in organic orchards in the Netherlands
Provedor de dados: 21
Autores: Jansonius, Pieter Jans.
Scab control in Conference pears is the bottleneck in organic growing. A group of growers,  advisers and researchers in the Netherlands is working on new approaches to organic  pear growing. Central to this approach is a reliable and good scab control. Changes in the  system of cultivation are sought which will enable this scab control with less fungicide.  This has become even more urgent since copper was banned as a fungicide in the  Netherlands. First results from trials on vigour control show that there is potency for  system changes that will enable a better scab control in organic growing. Scab incidence  was reduced in three trials with 34, 58 and 82% respectively. The project, in which also  other cultivation measures are being tested, will be...

Conflicting areas in the ethical debate on animal health and welfare
Provedor de dados: 21
Autores: Sundrum, Albert.
There is a far-reaching agreement within western society, that a high level of animal health and welfare can be regarded as an ethical value. An increasing number of consumers are interested to purchase products that derive from animal-friendly housing conditions. Often animal-friendly and organic products are affiliated. Although the prescriptions of the EURegulation on organic agriculture clearly exceed the minimal standards of conventional livestock production, they do not automatically lead to a high status of animal health and welfare. Animal health status emerges from complex interactions within a farm system and thus is not primarily related to the production method or to minimal standards. Literature reviews indicate profound discrepancies between...

Organic Farming excludes the use of synthetic chemicals to protect plants in the field or during grain storage and questions the use of antibiotics for livestock breeding or aquaculture. One way to limit major constraints of chemicals (pests and diseases) is to use active plants parts or plants-based products, as it has been described in the literature for plant and animal health. Our current work consists in building a knowledge database from existing literature and implementing exploration methods to support the extraction of knowledge by the potential users (smallholders, advisors, extensionists, researchers, producers, etc.). In early May 2018, the knowledge base gathered data from 227 published documents, dated from 1957 to 2017. Ninety-four percent...

Consequences of agro-biofuel production for greenhouse gas emissions
Provedor de dados: 21
Autores: Carter, Mette S.; Hauggaard-Nielsen, Henrik; Johansen, Anders; Ambus, Per.
Currently CO2 from fossil fuel combustion accounts for 57% of the global greenhouse gas emissions, whereas the strong greenhouse gases nitrous oxide (N2O) and methane (CH4) contribute with 8% and 14%, respectively (IPCC, 2007). Agricultural activity is the dominant source of N2O, which is mainly associated with the use of nitrogen based fertilizers in agricultural production. Replacing fossil fuel-derived energy by biomass-derived energy is commonly and with increasing emphasis proposed as a mean to mitigate the CO2 emissions. However, a recent analysis of global emission data proposes that accelerated emissions of N2O associated with the production of biomass for bio-fuel purposes will outweigh the avoided emissions of fossil fuel-derived CO2 (Crutzen et...

Autores: H., Hoste; L., Gaillard; Y., Le Frileux.
The objectives of the current study were to examine the potential effects of distribution of sainfoin hay on nematode parasitism  in a producing herd and to measure the consequences on milk production. The survey was performed in an experimental herd  of 120-dairy-goat farm during a whole 9-month grazing season. Every month, 60 goats received indoors on average 1.36 kg of  sainfoin hay for 10 days whereas the 60 remaining goats were used as controls, thus receiving the same amount of lucerne hay at  the same time. The nutritional values of both hays were comparable except that concentrations of condensed tannins was higher  in sainfoin than in lucerne hay, i.e. 2.52% versus 0.7% of diet DM. Intakes of the two types of hay were recorded along with  each...

This report was presented at the UK Organic Research 2002 Conference. All EU countries are obliged to conserve livestock genetic resources (UN Convention on Biological Diversity, Rio, 1992). In-situ conservation is regarded as the most favourable approach. For rare and endangered livestock breeds extensive and organic farming systems seem appropriate. Council Regulation (EC) No 1804/1999 on organic farming recommends keeping indigenous breeds and strains that have adapted to local conditions. This project analyses the current situation and develops future scenarios for Hinterwälder farms. Aspects of farm structure, housing system, marketing concept, farm viability as well as environmental services and social factors were analysed in an interdisciplinary...

Constraints to the sustainability of a stockless arable rotation

Autores: Cormack, W F.
The sustainability of an organic stockless arable rotation on a fertile soil in eastern England was assessed from 1990 to 2005. The good water and nutrient holding characteristics of the silty clay loam soil were well suited to a stockless organic rotation. Fertility-building clover crops were the most difficult to establish, and failed completely in some years despite one or two re-sowings. Crop yields were good, particularly for cereals, with an average for winter wheat of 7 t ha-1. Crop yield did not show any particular trend with time; there was no evidence of either a post conversion adjustment period, or a fall in yield due to declining fertility. High organic crop prices in the 1990s, resulted in significantly higher gross margins than from...

Carcass characteristics of sucking lambs (n= 40) of two breeds reared under conventional and organic conditions were analysed including objective and subjective parameters for fatness and conformation, meat and fat colour. Consumer acceptance was also studied using the home-use test. Results showed that the characteristics of the carcass of suckling lamb were similar for both types of production systems pointing out that organic production system did not affect fatness or muscle development. However, organic meat was darker (higher L* and a* values) probably related with the higher amount of exercise, although fat was not more yellow. In contrast consumers did not consider organic meat darker and there were not significant differences in appearance related...

Consumer attitudes in North-west England to organic and regional food
Provedor de dados: 21
Autores: Padel, S.
The market for organic foods in the UK is considered to be one of the leading ones in Europe, and world-wide is estimated to have a value of £1 billion (SA, 2003). The main reason why consumers buy organic food is considered to be health benefits, followed by taste. Of growing importance also are concerns for the environment and animal welfare, but these more altruistic concerns remain less important then personal ones. The rapid increase of demand for organic food over the last few years is seen to be the result of various food-scares (Farodoye, 1999; MINTEL, 1999; SA, 1999; Datamonitor, 2002). The development of the market appears, therefore, driven primarily by consumers, but retailers, especially the multiples, have had a key role in furthering growth,...

In a world where more and more organic products are mass produced, and where most consumers have little – if any – contact with the organic farmers who have produced their food, many people feel that the underlying principles of the organic movement are coming under threat. According to our research consumers are mostly interested in additional ethical attributes like “higher animal welfare standards”,  “regional/local production” and “fair producer prices” and they are willing to pay more for organic products which are produced following these higher standards. This gives producers the opportunity to differentiate their products in the organic market. When communicating these additional ethical attributes of organic food producers must take  care to use a...

Autores: Millock, Katrin; Wier, Mette; Andersen, Laura M.
In this paper, we use a unique combination of questionnaire data and real market purchase data on organic food to examine whether stated values can predict purchase behaviour. Our data cover around 2000 households during 1997-2001 and it is combined with a survey administered on the same panel in 2001. We distinguish between use values (health, taste and freshness attributes) and non-use values (environmental and animal welfare attributes). Non-use values are on average valued much more than use values according to consumers’ own statements. However, combining these consumer statements with their actual market behaviour, it becomes evident that the propensity to purchase organic increases significantly with the weight assigned to use values. We test this...

Marginal willingness to pay for eggs carrying different labels is estimated using observed Danish purchase data on individual level. Among other things the labels indicate environmental features and different levels of animal welfare for the hens that produce the eggs. The data on eggs are part of a very comprehensive panel data set covering household purchases of non-durables during a five year period. For each family a wide range of background characteristics are available. Detailed data on eggs are available during the one year period from July 1999 to June 2000 used in these estimations, Compared to simple statistics, such as the average market share of different egg types, econometric estimations make it possible to disentangle the effect of labels...

Consumer perception and communication on welfare in organic laying hen farming
Provedor de dados: 21
Autores: Heerkens, Jasper; Tuyttens, Frank.
A major reason for increased societal popularity of organic production systems is the growing general discontent with intensive farming practices. However, urbanization leads to limited knowledge of farming and farm animal welfare. Consumers believe organic farming leads to better animal welfare, although most health and welfare issues seen in conventional systems are also found in organic poultry systems. The majority of consumers do not translate attitude and good intention into action, the actual purchase of organic products. Understanding this intention-behaviour gap may lead to increased sales of organic products. Effective communication and education can create trust, added additional values and credibility, and may lead to structured perceptions,...

Autores: Meier, Claudia; Oehen, Bernadette.
Our food value chain is characterized by an ongoing concentration and standardization on all levels and a concomitant loss in diversity. Putting the breeding and multiplication of seeds back into the hands of farmers is one strategy to counteract this concentration process and embed diversity in the food value chain. In this project we investigated consumers’ preferences for so-called farmers’ varieties, using vegetables as an example.

Consumer Preferences for Organic Foods

Autores: Wier, Mette; Hansen, Lars Gaarn; Moerch Andersen, Laura; Millock, Katrin.
The Danish market is especially well suited for consumer analyses, because the Danish market for organic foods is relatively mature, meaning that it does not suffer seriously from the supply shortages and barriers, which dominate most of the markets outside Denmark. The well-functioning Danish market makes it possible to collect and analyse reliable data on purchases. Our study istinguishes itself by being based on observations of stated as well as actual purchasing behaviour of a large number of organic as well as conventional foods. The project applies information at the individual household level (panel data), which makes possible a detailed and informative approach. The panel data was provided by a marketing  research company.

In July 2010, the new mandatory EU logo for organic food was introduced to make the identification of organic products easier for consumers. In the present study we analysed how consumers in five EU countries view a mandatory EU logo for organic food to make recommendations for agrarian decision-makers and market actors in the organic sector. The study was based on a combination of qualitative and quantitative methods with consumers of organic food in the Czech Republic, Denmark, Germany, Italy and the United Kingdom. Firstly, 15 focus group discussions were conducted to reveal the spectrum of consumer perceptions. In a subsequent survey with 2042 participants consumer views on key issues were quantified. Finally, the results of the qualitative and...

Consumers and consumption of organic food in Central and Eastern European new member states of the European Union
Provedor de dados: 21
Autores: Zakowska-Biemans, S.
Despite the significant growth of organic farms and organically managed land in Central and Eastern European new member states of the European Union (CEE NMS) the consumption of organic food in these countries remains at the very low level. The main barriers to organic food consumption growth are low availability of organic food in the sale channels where contemporary CEE NMS consumers prefer to buy food, high prices for organic products, related, inter alia, to high distribution costs and high gross margins that reflect the undeveloped nature of organic markets in CEE NMS. Further development of the organic sector in CEE NMS will contribute to the growth of organic food consumption by overcoming the supply-related barriers. Nevertheless, to increase the...

Consumers’ Awareness, Demands and Preferences for Organic Vegetables: A Survey Study in Shiraz, Iran
Provedor de dados: 21
Autores: Alizadeh, Ali; Javanmardi, Jamal; Abdollazadeh, Negar; Liaghat, Zahra.
Some Iranian vegetable producers use a lot of chemicals, but not in a safe way or at the optimum level. There are several reports about chemical residues in vegetables that have serious side effects on human health and the environment in that country. On other hand, many Iranian farmers traditionally use organic production practices, but organic cultivation in Iran is not in accordance with international regulations. Since vegetables are the most important category of organic products, and since the future of organic agriculture will largely depend on consumer demand, a survey of 470 respondents was performed in Shiraz regarding their level of awareness about organic vegetables, their tendency to consume of organic vegetables, the effect of proper...

Consumers' demand for local organic food

Autores: Feldmann, Corinna; Hamm, Ulrich.
The development of local food systems as well as the growing consumer demand for locally produced food is becoming increasingly important for producers, retailers, and politicians alike. The question arises on how consumers decide, when they have to choose between local &amp; non-organic, local &amp; organic, and non-local &amp; organic products. Do local and organic food products compete against each other? Or do they complement one another? Information on consumer preferences and their willingness-to-pay is very important, as it helps to improve food marketing, communication, and policy making. Hence, it would be valuable to discuss results of current consumer research and practical experiences with practitioners, experts, and other interested parties at...

Agriculture has always been an important sector of the Iranian economy. For this reason, the investigation of consumers' demands and priorities in relation to organic products is our concern since no study has been conducted in this area in Iran. This paper aims to investigate consumers' knowledge concerning organic foodstuffs and the factors influencing consumption of organic product in the families of Mashhad so that some recommendations may finally be presented. In fact, while organic farming has been promoted as an environmentally-friendly approach and has been developed during the last few years in most developed countries, there is little emphasis placed on this in developing countries such as Iran.

Consumers' knowledge and information needs on organic aquaculture
Provedor de dados: 21
Autores: Feucht, Yvonne; Zander, Katrin.
Organic aquaculture is a reasonably new market segment and so far little is known about consumers’ knowledge and perception of organic aquaculture. Therefore the present article explores perceptions and knowledge of German consumers of organic aquaculture and related logos by using focus groups. One central result is that consumers were mainly unfamiliar with aquaculture in general. However, they had some clear ex-pectations regarding sustainable and specifically organic aquaculture. The use of drugs should be minimized, production systems should be close to nature and respect fish wel-fare. Obviously, test persons deduced their understanding of aquaculture from theirs of terrestrial animal husbandry. The study also shows consumers’ low awareness of the...

CONSUMERS’ KNOWLEDGE OF ORGANIC QUALITY MARKS
Provedor de dados: 21
Autores: Naspetti, Simona; Zanoli, Raffaele.
The study was conducted as part of a EU-wide qualitative survey on consumer perception of organic products, carried out in 8 European Countries (Austria, Denmark, Finland, France, Germany, Great Britain, Italy and Switzerland). It aimed to investigate consumer motivations and barriers related to buying organic products, in order to better understand the consumer decision-making process. In particular, the proposed paper focused on:    • the role of quality marks and certification labels on consumers’ knowledge of organic products;    • those aspects which determine and facilitate consumers confidence towards organic products;    • opportunities for the improvement of the communication and distribution strategy of these products.

Consumers motivations for buying local and organic products in developing vs developed countries

Autores: Sirieix, Lucie; Kledal, Paul; Santiago de Abreu, Lucimar.
Despite numerous studies reporting on organic consumer profiles, there is a gap in thorough understanding of consumers motivations for buying local and organic products. More precisely, do consumers prefer local products because they want to support local producers or do environment and  the question of food miles matter in their choice ? Besides, very little is known about organic consumers in developing countries, since most surveys are conducted in most developed countries. Our purpose is to fill this double gap, by conducing qualitative surveys based on individual interviews in four developing countries (Brazil, Egypt, Uganda and China) and two European countries, France and Denmark,  in order to study consumers choice for organic products from...

Consumers' Perceptions of Organic Foods in Bulgaria: Evidence from Semantic Differentials Application
Provedor de dados: 21
Autores: Vasileva, Elka; Ivanova, Daniela; Zabunov, Georgi; Tipova, Nina; Stefanov, Stiliyan.
The main tendency for most countries in Central and Eastern Europe is their organic production to be developed mainly for the purpose of export. This leads to the impossibility for organic products to be adapted to the local market and their price happens to be too high for consumers from these countries. The solution to this is the quick development and expansion of the domestic market for organic agricultural products and foods.  The market of organic products in Bulgaria enlarged significantly in the last few years. Although the share of organic food products in the general food market in the country is relatively small - less than 5 %, the total area under organic products in Bulgaria (cultivated and wild collected) is more than 250 thousand.

Consumers Values and Motives regarding Organic Food Products in Poland
Provedor de dados: 21
Autores: Zakowska-Biemans, Sylwia.
Poland, like all new European Union member states has experienced significant growth in organically managed land and the number of organic farms in the last few years. However, there are still many barriers to overcome to stimulate the consumption of organic foods. There is a need to learn more about the emotions, cognition and behaviour of Polish organic consumers in order to develop effective marketing strategies. Polish consumers are motivated to buy organic food because of its perceived health and safety attributes. The highest interest in organic food is observed among consumers who value animal welfare, environment protection and self-fulfilment.

More and more products are now both “organic and fair trade” but little is known about consumers perception of these double labels. In this article, we examine the importance of the “organic” and “fair trade” labels in the consumers’ buying decisions and the effect on the perception of the taste of the product by the consumers in the valuation of these labels. We also propose a consumers’ typology according to their degree of valuation of these labels, and analyze the  motivations of their behaviour.  Three consumers’ clusters were identified according to their reactions to the “organic and fair trade” label - the first cluster represents the people insensitive to the label’s presence, and contained nearly one half of the sample; for a second cluster, the...

Consumption of organic products:   Challenge for performance of supply chain.
Provedor de dados: 21
Autores: Kottila, Marja-Riitta; Rönni, Päivi.
Lengths of organic supply chains have been increased by the emergence of intermediaries between consumers and organic farmers. The involvement of supermarkets forces the organic chain to merge into the conventional food chain. The small segment of organic products and consumers creates a challenge for the performance of the organic chain. The case-studies described here were conducted to learn more about the performance of the chain. For this purpose, actors along the chain (from farmers to consumers) were interviewed. Three dimensions affecting performance were found, as well as three different levels of commitment to organics.

Contaminants and micro-organisms in organic and conventional food products

In the Netherlands we investigated animal and plant products on potentially hazardous contamination with heavy metals, mycotoxins, pesticide residues, patho-genic micro-organisms and nitrate. In most cases, the organically produced foods had equal or lower amounts of contaminants than conventionally pro-duced products.  These results conflict with a common idea that organic farming theoretically increases food safety risks. For many contaminants organic food showed a large diversity in the amount of contamina-tion. Experience with organic farming, managing and manure use partly explain these differences. Understanding of these cultivation parameters can help in further improvement of organic cultivation practices.

This work addresses possible ways in which animal manure might become contaminated by undesirable elements and how such manure might pose a risk to the health of soil organisms, animals, plants and humans. Research has shown that the pathways of organic compounds such as veterinary medicines and pesticides may be unpredictable and that undesirable elements can be transferred to the food chain. The basic principles of organic farming, in this case specially related to the principles of health, ecology and care, imply that special attentionshould be given to precaution and responsibility. These are key concerns in the management of organic farming. Taking these principles seriously, would mean a more restrictive practice on the use of animal manure from...

Autores: Jensen, Annette Nygaard; Storm, Christina; Baggesen, Dorte Lau; Forslund, Anita; Dalsgaard, Anders.
Due to disease outbreaks associated with contaminated vegetables it has been speculated to what extent this may be linked with application of animal manure as fertilizer, which is particularly practiced in organic vegetable production where conventional fertilizers are prohibited. A field survey was therefore performed to assess the survival and transfer of antibiotic-resistant E. coli from animal manure to lettuces, with E. coli serving as an indicator of bacterial enteric pathogens.

Autores: Larsen, Mette Krogh; Fretté, Xavier C.; Kristensen, Troels; Eriksen, J.; Søegaard, Karen; Nielsen, J.H.
The quality of organic milk is affected by feed composition, and especially the high use of legumes has been identified as the reason for high levels of polyunsaturated fatty acids, carotenoids and tocopherols in organic milk.     Four different pastures composed of mainly white clover (WCL), red clover (RCL), lucerne (LUC) or chicory (CIK), respectively, were established to investigate the influence of sward composition on the milk quality of grazing cows. On three occasions during the grazing period (May, June and August), groups of 12 Holstein cows were grazing the pastures for two weeks. About 70% of the daily dry matter intake was pasture, and the remaining dry matter intake was a mixture of oats, hay and minerals (82%, 16%, 2%, respectively). The...

Provedor de dados: 21
Autores: Saastamoinen, Marketta; Pihlava, Juha-Matti; Eurola, Merja.
Lignans are phytoestrogens found ubiquitously throughout the plant kingdom and thus are also  present in our diet. After ingestion lignans go through various transformations and in the end  they form mammalian lignans by microbial conversion. The amount of these mammalian lignans  in human body is linked to the reduced risk of various hormonal dependent cancers such as  breast cancer. Flaxseed (Linum usitatissimum L.) is one of the richest sources of lignans used in  the human diet. Unfortunately, flaxseed also picks up cadmium very efficiently from the soil,  which has to be kept in mind when choosing what regions to cultivate it in. SDG-lignan,  cadmium and lead contents were studied in linseed, flax and oil hemp variety samples. Oil  hemp samples were...

Continuous grazing in comparison to cutting management on an organic meadow in the eastern Alps
Provedor de dados: 21
Autores: Starz, Walter; Steinwidder, Andreas; Pfister, Rupert; Rohrer, Hannes.
Continuous grazing is an appropriate pasture system for dairy cows in low input milk production systems like organic farming. Grazing increases for economic reasons and is also caused by regulations in organic farming. If a dairy farm converts a pasture-based system,cows will start grazing on a cutting-managed meadow. Due to the utilisation changing from cutting to grazing, a conversion of the botanical composition and the quantity and quality yield is expected. To document and assess such conversions, a three-year field trial was carried out on the organic grassland and dairy farm of the AREC Raumberg-Gumpenstein between 2007 and 2009. In this study, changes in the botanical composition were found. In contrast to botanical composition, no significant...

Contribution of N from frequently chopped green manure to a succeeding crop of barley
Provedor de dados: 21
Autores: Frøseth, Randi Berland; Hansen, Sissel; Bakken, Anne Kjersti.
The aim of the present work was to study to what extent N in mulched green manure herbage contributes to spring barley grain yield the subsequent year. The green manure herbage was either chopped and left on stubble (GML) or removed (GMR). On silty clay loam with spring incorporated green manure the subsequent barley grain yield was 10% higher with GML than with GMR. The additional grain N yield of 4 kg ha-1 with GML corresponded to only 3 % of N in above-ground green manure biomass. On loamy soil with late autumn incorporated green manure the treatments did not affect the grain yield the subsequent year. How large part of the N that was lost through leaching or gaseous emissions and how large part that was built into soil organic matter was not measured....

Although it is the aim of organic farming to increase biodiversity, there is little information about the impact of organic farming on birds. From 2001 to 2003, the number of breeding birds was recorded annually on the organic experimental farm of the Institute of Organic Farming (600 ha), and on adjacent conventional and organic farms (60 ha and 40 ha) in Northern Germany. The number of skylark (Alauda arvensis) territories increased considerably after the conversion from conventional to organic farming on the premises of the Institute. Their number remained unvaried on the conventional farm. The highest density of skylark territories was found on the farm which has been under organic management for many years.

Short Food Supply Chains (SFSCs) are increasingly taken into consideration by policy and decision makers. In the European funded research project FOODLINKS an analysis of 19 cases was carried out in order to provide evidences on the diversity of SFSCs as well as to assess their contribution and potential to sustainability and health. SFSCs are varied in nature and practice. They exist in a range of forms in both commercial and non-commercial settings. In this paper a pair comparison of six different types of SFSCs was made: a)  two “Face to Face initiatives; b)  two proximate more complex SFSCs and c) also two spatially extended SFSCs. Key issues of the analysis were: activities, actors, type of products, area and territory, health and sustainability...

Autores: Fontaine, Laurence; Rolland, Bernard; Bernicot, Marie-Hélène.
Bread winter wheat is one of the most important cash crops for French organic farmers. Nevertheless, most of varieties available on the market were bred for conventional farming systems (with high inputs of mineral fertilizers and chemicals for crop defense). In order to obtain correct levels of yield and quality, it is important i) to screen current varieties to find the best suited for organic conditions, and ii) to rapidly obtain suitable varieties that are specifically bred for organic farming conditions. Bread wheat variety trials under organic conditions have been coordinated since the year 2001, to centralize and evaluate results at national level. The ringtest not only aims to compare varieties, but also to support organic breeding, as it provides...

Summary and Conclusions  For each indicator organic farming is ranked at least equal to conventional farming, while in the majority of environmental indicators organic farming performs better or much better. In two cases, the subjective confidence interval could allow conventional farming to appear as the preferable system (partly due to the lack of evident data). However, when considering the aggregation level of the indicator categories, the analysis becomes more uniform. With the exception of climate and air, organic farming performs better than conventional farming in all categories. None of the indicator categories showed that organic farming performed worse.  A summary assessment of all indicator categories was not carried out in the table, however,...

In organic apple growing protective applications with copper, sulphur or lime sulphur are  used for apple scab control. Protective applications have to be repeated when new leaves  unfold. The timing of protective sprays depends on the weather forecast. If forecasted  infection conditions fail to appear, treatments were for nothing. With curative control  agents available, the number of treatments could be reduced. In greenhouse trials we  tested control agents for their protective and curative efficiency against apple scab after  artificial inoculation of potted apple trees.

DL-3-amino-n-butanoic acid (BABA) was effective in controlling downy mildew incited by Bremia lactucae Regel in lettuce plants. The two isomers of BABA, DL-2-amino-n-butanoic acid and 4-amino-butanoic acid and its s-enantiomer were ineffective compares to BABA, while the r-enantiomer was more effective. The SAR compound NaSA and its functional analogue BTH (Bion) were also ineffective compared to BABA. In growth chambers, BABA was effective when applied as a foliar spray or as a soil drench. Effective control of the disease was apparent when BABA was applied up to 5 days before inoculation or 3 days after inoculation.

Control of common scab without the use of water
Provedor de dados: 21
Autores: Hilton, A J; Walker, R L; Wale, S J.
The most effective way to control common scab is by irrigating a potato crop at tuber initiation. With the introduction of legislation such as the Water Framework Directive this will become increasingly difficult. In this field experiment, we assessed the potential of a number of non-water measures for controlling this disease. Common scab on daughter tubers at harvest was reduced by applying rapeseed meal at 1 t ha-1 to the beds and then incorporating it into the soil, and adding a mixture of Trichoderma viride isolates into the furrow at planting. None of these treatments was as effective as using water.

Timing, type and duration of tillage operations and cropping practices are of importance for reducing the regeneration of perennial weeds and also for minimizing the environmental impacts of such operations. In the present work and with reference to previous publications we find that, based on the knowledge gained on growth patterns, sensitivity to competition, growth potential of roots and mechanical and management measures it is possible to coordinate control of perennial weeds with considerations of yield and reduced environmental impact.

Phytophthora infestans, the cause of late blight, is the most devastating pathogen in potatoes world-wide. To replace copper fungicides in organic potato production, we examined preparations based on plant extracts, micro-organisms, and other natural compounds for their effect on late blight in field trials as well as in vitro and in vivo. Most of this work we realised as participants of the EU project Blight-MOP. The majority of the preparations effectively inhibited P. infestans in vitro or in vivo on tomato plants. However, under field conditions and with applications once a week, commercial and experimental copper-free preparations failed to sufficiently control late blight.

Pollen beetle (Meligethes spp.) is a major yield-limiting factor in organic oilseed  production. Currently there are no effective methods available to control this beetle in  organic agriculture. From 2006 to 2008 work was carried out at Agroscope ARTReckenholz  to find suitable organically compatible plant protecting agents which are  effective against the beetle. A partial reduction in beetle infestation was observed  when liquid manure, lavender oil and rapeseed oil was applied. Dusting agents such  as ash and substances containing silicate (stone meal) were very efficient, almost  completely removing the beetle after application. However, beetle infestation  increased again after one or two days following application. Dusting substances in  combination...

Control of seed borne diseasees in organic seed propagation
Provedor de dados: 21
Autores: Borgen, Anders.
Introduction  The key control measure of plant diseases in organic agriculture is crop rotation, mixed cropping and moderate fertilization. A wide range of plant diseases can be controlled or minimized in this way. However, at least one group of plant diseases, the seed borne diseases, cannot. The seed borne diseases are not transmitted through the soil, and crop rotation is therefore an insufficient tool. Mixed cropping is impractical in seed propagation, where seed purity according to the seed legislation is imperative. The fertilization level primarily has an impact on facultative saprophytes, and not on the specialized seed pathogens.    Seed borne diseases were the first plant pathogens to be controlled by pesticides. Heavy metals has been used as...

In Denmark, most organic farmers uses organic propagated cereals and legumes for seeding, and all seed lots are  tested for infections of seed borne pathogens before sowing. About 50% of all see lots are discarded based on this assessment, but huge differences occur between year and crop, which makes planning of seed production impossible.  Some years up to 90% of the seed lots of a crop may be discarded e.g. peas in year 2000. The major cause of this are: Tilletia tritici in wheat, Dreschlera graminea, D. teres and Ustilago nuda in barley, Fusarium spp in triticale, and Ascochyta spp in peas. This situation calls for research focusing on this specific problem in the organic plant production.     Research in organic seed production, handling and use...

Autores: Nielsen, Bent; Borgen, Anders; Kristensen, Lars.
In production of organic seed it is important to have some control measures on seed borne diseases to avoid propagation and spread of serious diseases. Due to lack of acceptable treatment methods the only way for the moment is to discard seed lots with unacceptable infections. Experiments have been started to find new and alternative methods for controlling seed borne diseases. In spring barley the results show good effect with 5% acetic acid on leaf stripe (Pyrenophora graminea) but problems with unacceptable effects on seed germination have to be solved. The old method with hot water treatment can be used and the results indicate good results against leaf stripe using water at 55°C. The effect of hot water was enhanced by first soaking the seeds in water...

Provedor de dados: 21
Autores: Kienzle, J.; Zimmer, J.; Maxin, P.; Rank, H.; Bathon, H.; Zebitz, C.P.W.
The best application technique and application data for the treatments with Quassia extract against  the apple sawfly Hoplocampa testudinea Klug were tested. The spraying solution was distributed  best on the receptacle of the blossom – the place where the sawfly larvae feed before the enter the  blossom – when the treatment was effecttuated at fading blossom with a high amount of water  (about 500 l/ha/mTh). The addition of T/S forte, a wetting agent, could also improve the efficacy of  Quassia treatments in a lower dose. Thus, it is recommended to apply in fading blossom with addition  of T/S forte and high amounts of water to obtain the best effect. If the conditions for applications  are good and the infestation is not too high, the normally...

Autores: J., Kienzle; J., Zimmer; K., Klopp; P., Maxin; K., Yamada; H., Bathon; C.P.W., Zebitz; P., Ternes; H., Vogt.
The effect of Quassia extract on eggs and larvae of the apple sawfly Hoplocampa testudinea  was studied. The efficacy of this extract is mainly due to an oral toxicity to the  neonate sawfly larvae. The main active ingredients, Quassin and Neoquassin, were  tested separately. Wheras Quassin has a considerable efficacy also on older larvae,  Neoquassin is less efficient in this case. While Quassin and Neoquassin are found in  different Quassia sources in varying relations to each other and have different efficacy,  they have to be considered separately in the definition of extract quality by the content of  active ingredients. These findings mean, that the “egg maturity” is not important for application  date. Nevertheless, the application must take place...

Autores: Kienzle, J.; Buchleither, S.; Scheer, C.; Zebitz, C.P.W.
Several products were tested for their efficacy in control of the apple seed moth (Grapholita lobarzewskii  Ragonot). None of them had a good efficacy. With several treatments with Bacillus thuringiensis an efficacy  about 50 % could be achieved. An early treatment before egg-laying seem to improve the results. Quassia  extract (9 g Quassin/ha/m tree height) gave efficacy about 50-60 % even if treated only once. NeemAzal  gave only moderate efficacy (about 40-50 %). Mating disruption method was effective if the populations were  not too high when the treatements were started. With high populations there was no sufficient control in the  first year of application.

Abstract  The woolly apple aphid (Erisoma lanigerum Hausm.) has been recognised for some years as a serious pest in organic fruit growing where they may cause severe economic damage due to a lack of control strategies. Based on preliminary results a new project has been started in 2007 testing combinations of releasing earwigs and oil applications in order to develop an on-farm control strategy. In this paper we present preliminary results of the first year of the project´s field trials. They showed good efficacies for applying oil preparations by brush. The efficacy of releasing earwigs depended on the infestation intensity.

Control of venturia inaequalis: substitutes for and reduced use of copper
Provedor de dados: 21
Autores: Palm, Gerd; Klopp, Karsten; Kruse, Petra.
In 2001 eleven different apple scab control strategies with reduced copper use and copper substitutes were tested on an organic apple orchard near Hamburg, Germany. The strategies were tested on a six year old "Elstar" plantation. Among the different fungicides were copper sulphate, copper hydroxide, lime sulphur, sulphur, bacillus subtilis and "Biofa-Algenextrakt".  The results show that fruit scab as well as leave scab can be fairly well controlled by a lime sulphur strategy and the copper hydroxid strategies. Bad results were produced with the different copper sulphate strategies and bacillus subtilis, insufficient results with the sulphur strategies.

Autores: Zarb, John; Ghorbani, Reza; Juntharathep, Pintip; Shotton, Peter; Santos, Joanna; Wilcockson, Steve; Leifert, Carlo; Litterick, Audrey M; Bain, Ruaridh A; Wolfe, Martin.
This report was presented at the UK Organic Research 2002 Conference. Protective copper fungicides are currently used to control late blight in most organic production systems, but approval for their use in organic farming will be revoked in 2002. Evidence suggests that organic potato production will not be reliably economic in the absence of Cu. Current controls for late blight are reviewed including: variety selection/breeding for blight resistance, diversification strategies, agronomic strategies for the management of late blight, and alternative treatments to Cu-fungicides.

Controlling broad-leaved dock (Rumex obtusifolius) in grass clover mixtures
Provedor de dados: 21
Autores: van Eekeren, Nick; Fehér, L.; Smeding, Frans; Prins, Udo; Jansonius, PieterJans.
This article describes three experiments on the control of broad-leaved dock. Experiment 1: Dock seeds were ensiled in grass silages of different dry matter percentages; 23, 34 and 60% respectively. All silages showed a decline of seed vitality in time. Grass clover with dock seeds should be ensiled at a low dry matter percentage or remain in the silage bin for a longer period than 8 weeks. Experiment 2: In a potassium fertilisation trial on grass clover the development of dock was followed. After two years of potassium fertilisation, the number of dock and the root mass was not significant different between the fertilised and the unfertilised plots. It is concluded that potassium fertilisation at a low potassium status does not positively influence the...

Controlling insect pests of stored organic chamomile by controlled atmospheres
Provedor de dados: 21
Autores: Hashem, Yousry.
Different stages of Trupanea stellata and Lasioderma serricorne were exposed to four different gas mixtures differing in their CO2 content (20%, 40%, 60% and 80% CO2). In general, increase in carbon dioxide combined with decrease in oxygen resulted in increasing mortality. The gas mixture containing 80% CO2 was the most effective mixture to control the different stages of T. stellata (most tolerant than the different stages of L. serricorne insects). The use of this gas mixture to disinfest chamomile for 7day exposure in 30 m3 fumigation chamber under temperature range between 28.7-30.9oC, resulted in complete control.

Field trials on weed control in direct seeding with the use of natural phytotoxic ingredients (NPI) were carried out from 2011 to 2013 at the Agricultural Research Institute of Paraná state, Brazil (IAPAR).   Soybean was direct seeded into residues of precrop black oats (\textit{Avena strigosa)}. In a split-plot trial the whole-plot treatment consisted of two different weed densities. In the eight subplot treatments the effects of "natural phytotoxic ingredients" (NPI) on weed control was evaluated.  The two NPI formulations used in the experiment contained 50 L/ha Pine Oil (formulation ``Pine Oil'') or 50 L/ha d-Limonene (formulation ``Limonene''), both combined with 50 kg/ha NaCl. These formulations were applied once, twice, or three times in a weekly...

Conventional vs. organic cropping systems: yield of crops and weeds in Mediterranean environment
Provedor de dados: 21
Autores: Campiglia, Enio; Mancinelli , Roberto; Radicetti, Emanuele.
Agriculture must meet the twin challenge of feeding a growing population while simultaneously of minimizing its global environmental impacts. The organic farming, which is a system aimed at producing food with minimal harm to ecosystems, is often proposed as a possible solution. However, critics argue that organic agriculture may give lower yields and therefore more land is required in order to produce the same amount of food of the conventional farms, resulting in more widespread deforestation and biodiversity loss, thus undermining the environmental benefits of organic practices.  The long-term experiment was established in 2001 in order to compare organic vs. conventional cropping systems and inversion vs. non-inversion soil tillage. A 3-year crop...

The organic food market is constantly evolving and organic products are exchanged at multiple markets constituted by particular forms of interaction between producers and consumers. The aim of this paper is to explore how the market influences organic production by looking at the relation between the market and producers engagement towards trust and quality building as well as farm level production strategy. We distinguish between four different market agencements, an arrangement of actors with agency: 1) standardizing market agencement, 2) personalizing market agencement 3) virtualizing market agencement and 4) aesthetifying market agencement. Through qualitative interviews with organic producers, several different strategies are identified. The data...

Provedor de dados: 21
Autores: Escribano, A.J.; Gaspar, P.; Escribano, M.; Mesias, F.J.; Pulido, F.
INTRODUCTION: The Spanish goat sector's crisis has led to the abandonment of a large number of farms. At present, sector's expectations are reduced, which threatens farms' permanence. This in turn means a loss of agricultural biodiversity, reduced economic activity and loss of rural population. In this context, it is necessary to implement strategies to ensure farms' continuity . In this sense, the conversion to the organic model is proposed in the farms analyzed.   METHODOLOGY: To study the possibility and feasibility of such conversion an analysis of their structure (technical and economic characteristics), an assessment of farms' sustainability (based on social, economic and environmental parameters) has been carried out. For this purpose, the MESMIS...

Two sheep flocks were managed organically for two years from conversion under different lambing strategies (1 lambing/year vs. 3 lambings every two years). The second system was tested because pf a producer’s interest in high productivity, which is a guarantee of good economic results in conventional production.. Reproduction, feeding, lamb production, carcass quality, health (particularly internal parasitism), economic return of the flock, grass production, and pasture biodiversity were evaluated. The lambs were bred with low therapeutic inputs. No economic advantage of increasing lambing frequency was demonstrated, whereas this strategy complicated management and resulted in higher internal parasitic infection of the lambs, and finally showed lower...

Conversion of french suckler cattle farms to organic farming: adaptation of the system and its economic consequences
Provedor de dados: 21
Autores: Veysset, Patrick.
French suckler farmers need advice on the impact of the conversion to OF. To help them with their decision-making process, we constructed an LP model that optimises the farming system, taking OF constraints and nitrogen balance into account. According to the model, the shift to OF had a greater impact on a mixed crop-livestock farm system than on that of a grassland farm. As a result of the very high cost of organic N fertiliser and the necessity of maintaining the N balance, the shift to OF in the case of the mixed farm resulted in less emphasis on cereal and more emphasis on livestock. For this type of farm, a significant drop in its proportional costs due to extensification was sufficient to maintain the overall gross margin of the holding. For the...

This study aims to understand the process of conversion from conventional to organic farming in Canada.   Specifically, it looks at what factors have affected this decision and if this production system improved the prospects for sustainability. In order to achieve these objectives this study uses a socio-ecological approach and focuses on organic farmers in Ontario. Besides including a bibliographic review, organic agricultural leaders were surveyed and life story interviews were conducted with producers. The results showed that the decision to become organic is influenced by the type of farmers, their context, and their rationale for conversion. The reasons for converting to organic depended not only on economic factors, but also socio-cultural and...

Conversion to Organic Farming as an Opportunity for Syrian Farmers of Fresh Fruit and Vegetables: An Application of the Theory of Planned Behaviour
Provedor de dados: 21
Autores: Issa, Irwa; Hamm, Ulrich.
The export of organic fruit and vegetables to the European Union might offer a great opportunity for Syrian farmers and exporters. Yet, the organic sector in Syria is comparatively young and only a very small area of fresh fruit and vegetables (FFV) is organically managed. To date, little is known about Syrian farmers’ attitudes towards organic fruit and vegetable production. Therefore, the aim of this study was to explore the intentions and attitudes of Syrian farmers of FFV towards organic farming and the likelihood of converting their farms to organic production within the next five years. The study was based on a survey among 266 Syrian farmers. The theory of planned behaviour (TPB) was used as theoretical framework and partial least squares structural...

Conversion to organic farming; experiences from Punjab and Uttarakhand

This research indicates that it is possible for farmers to convert from an intensive conventional system (Punjab) to organic farming, or to make a living on a smallholding in difficult terrain (Uttarakhand). Both alternatives can provide a good livelihood with sustainable methods. I also found that the organizations that assist the farmers in this transition are crucial, because they teach the farmers new methods and give practical and moral support during a time when they feel uncertain making such a large change in how they make their living. One of them is Navdanya, which has been working in Uttarakhand and in several other states in India for nearly three decades. The organization trains and supports farmers converting to organic practices and helps to...

Converting Europe - the potential for organic farming as mainstream
Provedor de dados: 21
Autores: Lampkin, Nic.
Organic farming is increasingly recognised, by consumers, farmers, environmentalists and policy-makers, as one of a number of possible models for environmental, social and financial sustainability in agriculture. It has taken a long time to get this far. Organic farming’s roots can be traced back more than 100 years. Certified organic production dates back 25-30 years (70 years in the case of Demeter-certified bio-dynamic production). Yet little more than one percent of agriculture in Europe is organic, and much less than that in other parts of the world. Many have argued that organic farming will never capture the hearts and minds of the majority of farmers, because it is too idealistic and restrictive. What is needed, they argue, is an intermediate...

Co-operative or coyote? Producers' choice between intermediary purchasers and Fairtrade and organic cooperatives in Chiapas
Provedor de dados: 21
Autores: Milford, Anna Birgitte.
This study of organic and Fairtrade co-operatives in Mexico aims to find out why many coffee producers prefer not to join the certified co-operatives, despite their higher price offer. A study of costs of production of organic coffee concludes that it implies more work, but not necessarily higher yields. A main conclusion of the investigation is that the compulsory organic production methods deters many producers from entering the co-operatives, and that it is more attractive for producers with more free family labour, and less attractive for producers with very little coffee land. However, the study also shows that it is not only economic factors that influence the decisions of the producers on where to sell their coffee.  Previous studies have shown that...

Cooperatives as a tool for poverty alleviation and food production in Sub-Saharan Africa
Provedor de dados: 21
Autores: Sumelius, John; Tenaw, Shimelles.
Self-sufficiency in food production can be guaranteed when agriculture is practiced on the basis of reasonable policy and optimal system. In doing so, the possibility of  securing food production becomes possible in sub-SaharanAfrica. In this regard cooperatives have played a significant role. The present food production system in many  sub-Saharan African countries is such that much of the food supply is produced by the small-scale farmers owning less than 5 hectares of arable land and with 75 percent or moreowning less than one hectare. Obviously this is a strong reason for the creation of poverty to which attention should be drawn to. Farmer controlled cooperatives can assist poor farmers in strengthening their position in the food chain.  In addition...

Coping with citizen demands: a field study of suckling processes in dairy herds
Provedor de dados: 21
Autores: Disenhaus, C.; Michaud, A.; Genot, N.; Valenzisi, L.; Pomiès, D.; Martin, B.; Chassaing, C.; Le Cozler, Y.
In dairy farms calves and cows are usually separated shortly after birth but this practice raises the question of animal welfare. This social concern may lead to bring back dairy calves to their mother. Even though suckling is quite seldom in dairy production, some farmers are using such a practice for many years. The present study aims to better know farmer’s motivations, practical implementation and farmer’s perception of the impact of suckling on performance and animal behaviour. In January 2018 a semi-quantitative survey was performed on 44 farms where calves suckle at least 24 hours their mother or a nurse cow. The farming systems differed on the size (20 to 140 cows), the type (19 conventional, 25 organic farms), the suckling (28 by the mothers, 16...

Copper reduction and copper replacement - results and experiences of 12 years of on farm research
Provedor de dados: 21
Autores: Hofmann, Uwe.
Copper is a very common pesticide in organic viticulture, used against different diseases. But it is long term toxic for soils. That is why organic winegrowers try to reduce its use. Since 1988 ECO-Consult and the Organic Winegrowers Association of Germany (BÖW) has coordinated a on farm research program concerning copper reduction in organic vine protection.   As a result of this reseach, the document outlines a plant protection strategy against Plasmopara viticola (downy mildew).  Tables:  - Use of Copper (kg/ha/a) by german organic wine growers in 1996 to 1998  - Frequency of Plasmopara viticola infection on clusters in the years 1990 to 2000 (ring trial - on farm research)

Copper replacement in organic viticulture - state of the art in legislation and research
Provedor de dados: 21
Autores: Berkelmann-Löhnertz, Beate.
In European viticulture, downy mildew (Plasmopara viticola (Berk. &amp; Curt.) Berl. &amp; de Toni) is one of the most dangerous diseases affecting grapes, causing significant damage and severe decreases of product quality.  European organic viticulture is predominantly based on copper applications to control this disease. Due to environmental problems incurred by copper applications, the European Commission decided to limit the use of certain copper products in organic viticulture. This should be achieved by the year 2002 (cf. EC 1488/97). Therefore, the Commission recommends testing alternative strategies in downy mildew control in line with EC 2092/91.  In the last decade, specific actions were realized to investigate, apply and support alternative...

The overall objective of the project CorePig is to promote animal health and welfare in organic pig herds in Europe. The variation in pig health between organic herds is likely to be caused by different management routines in the herds. To improve animal welfare it is therefore important to investigate the correlation between management and parasite/disease occurrence, and based on this, to develop a disease management tool applicable on farm. This will be achieved by carrying out the following three components:  • To conduct an international knowledge synthesis for identifying needs for future research into disease and parasite prevention in organic pig production  • To estimate risk factors for selected diseases and parasites in pigs in European organic...

Corporate responsibility
Provedor de dados: 21
Autores: Jensen, Karsten Klint.
Appeals to corporate responsibility often simply take for granted that businesses have ethical responsibilities that go beyond just respecting the law. This paper addresses arguments to the effect that businesses have no such responsibilities. The interesting claim is not that businesses have no ethical responsibility at all but that their primal responsibility is to increase their profits. The extent to which there is reason to take such arguments seriously delineates the limits of corporate responsibility.    It is shown that Milton Friedman’s famous right-based argument fails, because it assumes social responsibility to imply that the corporate executive acts against the interests of the share holders. But why should not share holders be ethical...

Autores: Ortolani, Livia; Kristensen, Hanne L.; Campanelli, Gabriele; Bavec, Martina; Bavec, Franc; von Fragstein, Peter; Bergmam, Astrid; Leteo, Fabrizio; Canali, Stefano.
This paper presents the findings of an assessment aimed to evaluate, in terms of cost and energy consumption, the introduction of living mulches in different organic vegetable systems producing cauliflower. The study was carried out in three European countries (IT, SLO and DK) in the frame of the InterVeg project (Core Organic II). The achievements demonstrated that, in economic terms, farmers’ choice of a specific technique, like living mulch instead of sole cropping, can be influenced by two key elements: human labor and fossil fuel consumption. Different organic systems have a different proportion in using the two inputs depending on the specific farm strategy.

Cost driver in the organic meat market in Germany -  specific problem of the organic sector?
Provedor de dados: 21
Autores: Beukert, Christoph; Simons, Johannes; Hartmann, Monika.
High prices for organic meat and meat products in Germany are caused especially by small scale production schemes and the special behaviour of the market participants. Special requirements for organic production systems play a minor role. The German market for organic meat is a co-ordinated market with restricted access, as an analysis based on expert interviews shows. Prevalent forms of co-ordination are contract production and the pooling of output and prices. Due to this situation, the margin between the producer and the consumer price is higher than on a competitive market. But the conditions on organic markets are changing as it becomes more difficult to restrict market access. For the future, the generation of demand could help to overcome the...

Costs and benefits of farming fish with selected behavioural and physiological traits
Provedor de dados: 21
Autores: Skov, Peter Vilhelm; Gregersen, Joao de Jesus; Jokumsen, Alfred.
The timing with which salmonid larvae emerge from their gravel nests is considered to be associated with a particular suite of behavioural and physiological traits. In aquaculture, traits of interest to production include aggressiveness, dominance and resilience to stress. The earliest emerging fraction is generally considered to possess these traits, and fish in this fraction may be perceived as being more robust. It is speculated that there may be advantages to selectively farm fish that are more robust, particularly if feed utilization is improved and disease is less prevalent. In the present study a series of experiments were performed, with the purpose of characterising behavioural, metabolic and production related traits in rainbow trout juveniles....

Could a different management routine that strengthens the mother-offspring bond contribute to a more efficient organic piglet production?
Provedor de dados: 21
Autores: Thomsson, O.; Bergqvist, A.-S.; Eliasson-Selling, L.; Sjunnesson, Y.; Magnusson, U.
In current Swedish organic piglet production full reproductive potential of the sows and growth potential of piglets are not achieved. The efficiency is held back by occurrence of lactational oestrus, low litter weight and large weight variation within litter. Therefore it is critical that these obstacles are reduced in a way that is easy to adapt in practice and does not contradict the ideas behind organic animal husbandry.   This project aims to an improvement of the conditions needed to efficiently produce organic piglets in a batch wise manner. The batch wise breeding will reduce production costs and increase disease control.   Our preliminary results indicate that the sow’s weaning to oestrus interval can be affected by the time spent in individual...

Cover Crop Productivity in Contrasting Growing Conditions and Influence on the Subsequent Crop
Provedor de dados: 21
Autores: Wendling, Marina; Büchi, Lucie; Jeangros, Bernard; Walter, Achim; Charles, Raphael.
In arable systems, cover crops provide multiple ecosystem services involved in soil protection and fertility. They can efficiently compete against weeds, control erosion or recycle nutrients. The supply of these services is however largely dependent on cover crop growth as most of the services are related to biomass production. The choice of a cover crop adapted to the growing conditions is thus essential. Growing mixtures instead of sole crops is expected to be a way to overcome variable growing conditions and to insure high biomass production.Different field trials have been conducted from 2013 to 2016 in Nyon, Switzerland to assess cover crop biomass production and stability, and their influence on the following crop. Indian mustard, field pea, black...

With the objective to identify the effect of soil cultivation and nitrogen supply in organic production of black currant a field trial was planted autumn 1996 under Unsprayed conditions. The bush rows were cleaned mechanically for weed, and cover crops were established in the alleyways. During establishment all four cover crops gave a sufficient nitrogen supply. The level of nitrogen in soil and the growth were smallest in the annual sown cover crop. Minirhitzotrons were used to follow black currant root growth in total mechanical cleaned plots and plots with sown alleyways.

Cover Crops to Secure Low Herbicide Weed Control Strategies in Maize Grown with Reduced Tillage
Provedor de dados: 21
Autores: Amossé, Camille; Büchi, Lucie; Wendling, Marina; Jeangros, Bernard; Charles, Raphael.
As a key-element of conservation agriculture, the occasional or systematic suppression of full-inversion ploughing implies an adaptation of the cropping system. To assess the ability of cover crops to control weeds in a subsequent maize crop grown with reduced tillage, three annual experiments were implemented at the research station of Agroscope  Changins,  Nyon, Switzerland. Ten non-wintering cover crop (CC) species were sown in mid-summer and compared to a bare soil treatment in strip-plot experiments including different weeding strategies according to integrated weed management rules. In case of a predictable impasse for weed control, an alternative management option was chosen 1) at the end of winter: total herbicide application instead of no...

Within the framework of “Organic HACCP” a systematic analysis was carried out among selected certified organic food production chains (wheat bread, cabbage, tomatoes, apples, wine, eggs, milk) to investigate current procedures of production management and quality assurance related to the chains. Relevant critical control points (CCPs) were accordingly assessed for the single management steps of production, wholesale, processing, transport and retail.     Therefore, a questionnaire was set up by experts knowledgeable in the areas of seven quality and safety criteria such as microbial toxins and abiotic contaminants, nutrient content and food additives, pathogens, freshness and taste, natural plant toxicants, fraud, social and ethical aspects. Questions were...

Crop diversification in the future cropping systems
Provedor de dados: 21
Autores: Keskitalo, Marjo; Mäkinen, Taina.
According to the results, the selected special crops may attract pollinators such as  honeybees and flower flies more than conventionally cultivated crops. Also, the  number of weed species among special crops may be higher than the number of  weeds identified among barley and timothy. The high amount of dry weight and  weed species among the special crops may be due to the challenges of herbicide  treatments. These results may be used when strategies for more diversified  cropping systems, where selected special crops could be cultivated as a rotation  with conventionally corps, are planned.

Crop diversity - a crucial remedy for weed management in organic cropping
Provedor de dados: 21
Autores: Salonen, Jukka; Zarina, Livija; Melander, Bo.
A wide variety of crop species in crop rotations has turned out an essential means to obtain diversification in organic cropping systems. Moreover, the potential of cover crops to assist the main crop in weed suppression has been studied in Denmark, Finland and Latvia. Long-term field experiments in Denmark and Latvia demonstrated that crops with different life cycles and life spans in crop sequence resulted in a relatively low and manageable pressure of annual weeds. The study was part of the PRODIVA project (Core Organic Plus) in which crop diversification for better weed management has been studied and presented in the 18th EWRS Symposium.

The possibilities for increasing grain yields and reducing N leaching losses in organic ce-real production through manipulation of crop rotation design were investigated in a field experiment on different soil types in Denmark from 1997 to 2000. Three experimental fac-tors were included in the experiment in a factorial design: 1) proportion of grass-clover and pulses in the rotation, 2) catch crop (with and without), and 3) manure (with and with-out). Three four-course rotations were compared (Table 1). Two of the rotations had one year of grass-clover as a green manure crop, either followed by spring wheat or by winter wheat. The grass-clover was replaced by winter cereals in the third rotation. Animal ma-nure was applied as slurry in rates corresponding...

Three factors are included in a factorial field experiment: 1) fraction of grass-clover and pulses in the rotation (crop rotation), 2) catch crop (with or without catch crop), and 3) manure (with or without animal manure).  Manure is applied as slurry in rates corresponding to 40 % of the nitrogen demand.  Grain yields for three sites and three years of the experiment are presented for two four-course rotations.  One rotation has a green-manure crop, which is replaced by winter wheat in the other rotation.    The use of manure significantly increased grain yield of the cereal crops in most cases.  The positive effects of the catch crops were mainly observed in the spring cereals.  The largest rotation yields were obtained in the crop rotation without a...

Crop protection in organic agriculture - a simple matter?
Provedor de dados: 21
Autores: Litterick, Audrey M; Watson, Christine A; Atkinson, David.
This report was presented at the UK Organic Research 2002 Conference. Crop protection strategies in organic agriculture and horticulture aim to prevent pest, disease and weed problems through optimisation of the cropping system as a whole. Choice of crops and varieties within the rotation and use of appropriate husbandry practices are critical to the success of the system and direct curative action against pests and diseases is rarely necessary. Research is urgently needed to determine strategies for control of key pests and diseases in organic systems if UK organic agriculture is to expand to meet increasing consumer demand. This paper describes current prevention and control strategies for pests, diseases and weeds in UK organic agriculture and...

Crop rotation and crop management effects on cereal yields in arable organic farming in Denmark
Provedor de dados: 21
Autores: Olesen, J.E.; Askegaard, M.; Rasmussen, I.A.; Kristensen, K.
One of the main challenges in organic crop production is to ensure high and stable crop yields. In this study we used data from a 12 year old crop rotation experiment in Denmark to estimate the contribution of various management factors to yields of winter and spring cereals. The experiment included three factors in two replicates: 1) Grass-clover green manure crop (with and without), 2) catch crop (with and without), and 3) animal manure (with and without). Animal manure was the most important factor for increasing grain yield of cereal crops, but also grass-clover and catch crop contributed considerably to increasing yields. The grass-clover had a larger long-term effect on grain yields on the sandy loam soils than on the sandy soil. Yields were...

Crop rotation planning tool for organic farms
Provedor de dados: 21
Autores: Bachinger, J.; Zander, P.
To support the development and expansion of organic farming, more research is needed to optimise the function and practices of individual farms. Furthermore, it is important to assess the ecological effects of organic farming on a regional scale in order to show potential ad-vantages of organic farming compared to conventional farming. Both issues require model-ling of cropping methods and crop rotations. The authors present a rule-based model for the generation of site-specific and agronomically suitable crop rotations. Site-specific estimation modules for yields, nitrogen balance, risk of weed problems, phytosanitary restrictions for crop rotations,  and economic costs and benefits allow the generation and selection of eco-nomically optimal,...

Crop rotations for grain production
Provedor de dados: 21
Autores: Olesen, Jørgen E.; Rasmussen, Ilse Ankær; Askegaard, Margrethe.
There is an increasing demand for organically grown cereal grains in Denmark, which is expected to cause a change in the typical organic farm structure away from dairy farming and towards arable farming. Such a change may reduce the stability of the farming systems, because of decreasing soil fertility and problems with weed control. There have only been a limited number of studies under temperate conditions in Europe and North America, where different crop rotations have been compared under organic farming or similar production conditions.

The effects of crop type, and of fertility and crop protection management within crops, on ground beetle species activity were investigated using the Nafferton Factorial Systems Comparison Experiment, using pitfall traps in 2005. Thirteen species gave significant responses to crop type, with seven showing a preference for cereals and none for grass/clover. There were 22 significant responses to fertility and six to crop protection within crop types. Sixteen of the responses to fertility and four to crop protection resulted in more activity in organically managed plots. Fertility effects were found most in wheat, barley and grass/clover whilst crop protection effects were mainly in beans and vegetables. A better knowledge of the effects of fertility...

This report was presented at the UK Organic Research 2002 Conference. In order to develop organic dairy production a system study called “The Öjebyn Project” was started in 1990. Öjebyn is a research station of The Swedish University of Agricultural Sciences in northern Sweden. There is 104 hectares of arable land; 58 hectares are grown organically and 46 hectares are grown conventionally. The feed produced on the farm was fed to around 50 dairy cows in each system. There has been a crop rotation of six years and a careful handling of farmyard manure and urine from the dairy cows. The crop yields have been recorded for twelve years as have the quality of each crop in terms of energy, protein and mineral content (P, K, Ca, and Mg). The difference in yield...

The Windsor Organic Research Trial (WORT) is a farming systems experiment initiated in 2003 to investigate alternative strategies for transitioning to certified organic vegetable production that compares the influence of transition schemes that differ in management intensity (cropping, tillage) and organic matter inputs on weeds; soil organic matter and nutrient availability; soil invertebrate communities; and the relationship between soil fertility, plant health and insect/disease pressure.  Soil quality was improved during transition in all systems.  Conventional soil tests were unable to document differences among systems that were reflected in biotic indicators.  The pasture-based transition system was superior.

Cropping systems with winter wheat or spring wheat? Root growth, catch crops, nitrogen leaching and baking quality
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian; Pedersen, Lene.
In organic farming winter wheat is typically grown after good pre-crops, as it pays well for this in terms of yield and quality. However, winter wheat develops slowly during the autumn, and much nitrate may be lost by leaching before spring. System with catch crops followed by spring wheat, or maybe catch crops intercropped with winter wheat could improve the utilization of the pre-crop effects in wheat cropping. In this experiment we studied wheat and catch crop root growth, crop and soil N dynamics, and effects on yield and baking quality in wheat cropping systems with catch crops.  The results showed that the com-bination of catch crops and spring wheat was ideal for resource use, but also that winter wheat had a much deeper root system (c. 2.0 m) than...

This farm-scale analysis of the three-year transition to organic from conventional vegetable production tracked the changes in crop, soil, pest and management on two ranches (40 and 47 ha) in the Salinas Valley, California. Many small plantings of a diverse set of cash crop and cover crop species were used, as compared to only a few species in large monocultures in conventional production. The general trends with time were: increase in soil biological indicators, low soil nitrate pools, adequate crop nutrients, minor disease and weed problems, and sporadic mild insect damage. Some crops and cultivars consistently produced higher yields than others, relative to the maximum yield for a given crop. Differences in insect and disease damage were also observed....

Circadian rhythms established by the endogenous clocks enable organisms to anticipate periodic and cyclic changes in their environment. This internal time-keeping system is highly conserved amongst animals and provides them with adaptive advantages as biological processes can be scheduled to occur at the most crucial times of the day. Circadian rhythm is emerging as an important regulator of immune functions. However, there is a paucity of information on the influence of this biological phenomenon in the immune mechanisms of teleost fish. A series of studies was conducted to investigate the circadian rhythms of systemic and mucosal innate immunity using model (i.e., zebrafish, Danio rerio) and non-model (i.e., permit, Trachinotus falcatus; rainbow trout,...

The objectives of the interdisciplinary research project (AGIP) starting in march  2006 are ascertainment and assessment of the impact of different agricultural production processes and production intensities. Furthermore, the impact of different ways of food preparation concerning anthocyanin content and antioxidative capacity in selected cultivated plants will be tested. Main focus will be on potatoes due to the fact that potatoes as a staple food are consumed in large quantities....

Current achievements and future directions of physical weed control in Europe
Provedor de dados: 21
Autores: Melander, Bo.
This paper reviews major results achieved with physical weed control methods and strategies especially adapted for horticultural and agricultural crops. Mechanical methods, such as weed harrowing and inter-row hoeing, have provided promising results in cereals, pulse and oil seed rape, particularly when they are part of a strategy that also involves cultural methods such as fertiliser placement or crop seed vigour. In row crops, intra-row weeds constitute a major challenge, and research has mainly aimed at replacing laborious hand weeding with mechanization. A number of investigations have focussed on optimising the use of thermal and mechanical methods against intra-row weeds. And new methods are now under investigation such as robotic weeding for row...

Current downy mildew control strategies in Swiss organic vineyards
Provedor de dados: 21
Autores: Tamm, Lucius; Amsler, Thomas; Schaerer, Hansjakob; Lévite, Dominique; Häseli, Andreas.
The currently used downy mildew control strategies in vitis vinifera in Switzerland are based on the use of acidified clay products combined with copper and sulphur.   Data from 1997-2003 show that acidified clay products are a valuable alternative to control downy mil-dew of grapevine in conditions of medium rain fall, good spray timing and with a good application tech-nique. The limits of these products show under heavy rain conditions and when there is high disease pressure.

Current situations in organic cereal seed offer in the Czech Republic
Provedor de dados: 21
Autores: Konvalina, Petr; Stehno, Zdenek; Capouchova, Ivana; Huda, Petr; Moudry, Jan; Moudry, Jan (Jr.).
Organic farmers are obliged, in compliance with the valid legislation, to use seed originating from the organic production when establishing the crop stands. In a survey we found certified organic cereal seed is used on 6 %, conventional untreated seed on 37 %, and farm seed on 57 % (of the organically farmed area in the Czech Republic). The main reasons for that are as follows: the insufficient surface of land intended for the reproduction of organic seed, the low proportion of accepted seed coming from the accepted reproduction surface. Therefore, low-quality farm seed is used on a large proportion of organically farmed land, which has a negative effect on the yield level of the cereals. These observations were also confirmed by results obtained in a...

Abstract  In this paper some current data on organic farming are presented, based on the global survey on organic farming carried out 2007/2008 by the Research Institute of Organic Agriculture FiBL, the International Federation of Organic Agriculture Movements IFOAM and Foundation Ecology &amp; Agriculture (SOEL).    Organic agriculture is developing rapidly and is now practiced in more than 130 countries of the world. Its share of agricultural land and farms continues to grow in many countries. According to the latest survey on global organic farming, 30.4 million hectares of agricultural land were managed organically at the end of 2006, constituting a growth of 1.8 million hectares compared to 2005. Additionally, according to this survey, there are more...

Current World Status of Organic Temperate Fruits
Provedor de dados: 21
Autores: Granatstein, David; Kirby, Elisabeth; Willer, Helga.
Consumption of organic food has steadily increased in the primary markets of the European Union and North America.  However, the statistical information base to describe this growth is either incomplete or inaccessible, and sometimes inaccurate.  In the U.S., fruits and vegetables make up 40% of organic food sales, implying that the expanding overall market has also increased demand for organic temperate fruits such as apple, grape, and strawberry.  Organic fruit in several European countries comprises over 5% of all fruit sales.  Data on organic temperate fruit production have been compiled by FiBL and Washington State University.  In 2006, there were at least 250,000 ha of organic temperate fruit (pome, stone, grapes, and berries) under production...

Cut fallow to replace black fallow in an organic production system
Provedor de dados: 21
Autores: Bergkvist, Göran; Mangerud, Kjell; Magnuski, Ewa; Brandsæter, Lars Olav.
Couch grass (Elymus repens) has large impact on yield and management strategies in temperate areas of the world. The control is to a large extent based on repeated soil cultivations in organic farming. Our aim was to investigate methods to improve the competitive effect of white clover by management. The hypothesis was that cutting (fragmentation) of the rhizomes by making slits in the soil by a spade (spading) would increase the number of couch grass shoots, thus improve the effect of repeated mowing. We conclude that Cross cutting to 10 cm could reduce the amount of rhizomes, but that the effect is variable. We also conclude that the cross cutting do not improve the effect of mowing. Cross cutting reduce the amounts of couch grass shoots.

Czech organic farmers’ perception of landscape elements
Provedor de dados: 21
Autores: Dytrtova, Karolina; Sarapatka, Borivoj.
This paper aims to identify the main aspects of farmers´ motivation to farm organically and their activities relating to changes in landscape composition. Organic farmers’ perceptions of landscape elements were observed through questionnaires completed by 87 farmers in the Czech Republic. The majority of farmers (88.5%) stated that environment-friendly farming practices were the main reason to enter the organic farming system. A large number of farmers (69%) stated that they have problems with some constraining conditions and rules in agri-environmental measures. Regarding the size of farms, small farms were more willing to devote part of their farmland to landscape elements. Respondents who farmed in LFA areas and landscape protected areas mentioned more...

Dairy health in German organic farming - an intervention study on lameness and the implementation of herd health plans
Provedor de dados: 21
Autores: March, Solveig; Brinkmann, Jan; Winckler, Christoph.
A pilot study carried out in 2002/2003 (50 farms) revealed that production diseases such as mastitis, lameness and metabolic disorders play a considerable role in german organic dairy farming. In a follow-up project, an intervention study on lameness is currrently being carried out in 43 cubicle housed Holstein Friesian herds. Farms are monitored at 3-months intervals for two years. The average baseline lameness prevalence was 26%. Preliminary findings suggest a beneficial effect of access to pasture during summer and improvements due to intervention measures (housing, management) taken in approximately half of the farms. In a third step, herd health plans with regard to mastitis, lameness, metabolic disorders, reproductive disorders and calf diseases will...

Danish bathroom stories – a socio-technical study of what the present renovation boom is about
Provedor de dados: 21
Autores: Quitzau, Maj-Britt.
This paper explores changes in ordinary daily behaviour in relation to bathroom renovations in Denmark. Much suggests that new expectations evolve in connection to such renovations and that these changes could have long-term environmental impacts. The aim of this paper is to get a deeper understanding of how the production and reproduction of cultural meanings are interconnected with the changes in the bathroom. On the basis of general remarks about cultural meanings in connection to the bathroom, I discuss some general characteristics of modern bathroom ideas. My point is to elucidate the simultaneous rootedness and contextual determination of bathroom ideas. Hereafter, I examine two empirical examples in order to study the actual process of bathroom...

Danish organic food demand - Separability and Substitution Patterns
Provedor de dados: 21
Autores: Hansen, Lars Gårn.
Most studies of organic food demand are based on questionairs focussing on buying motives.   Only a handful of studies estimate organic food demand and these all focus on food submarkets and must assume separability of the organic/non-oragnic nest of analysed food from other food submarkets. The soundness of this separability assumption may nevertheless be questioned since general attributes such as animal welfare and environmental effects are cited as buying motives for organic variants irrespective of food type in most surveys. The assumption of separabilety of nests of organic/non-oragnic variants of foods has, however, not been tested empirically. In this paper we exploit unique Danish micro level data where all food demand has been registered on a...

Unvorhersehbare und zunehmend unsichere klimatische Bedingungen werden nicht nur abiotische (Hitze, Trockenheit) sondern auch biotische Stressfaktoren (unberechenbares und zunehmendes Auftreten von Pathogenen und Schädlingen) auf die Kulturpflanzen erhöhen. Externe Inputs alleine können diese Probleme nicht entschärfen. Zukünftige landwirtschaftliche Systeme müssen deutlich flexibler auf Stress reagieren können. Vor allem innerhalb ökologischer low-input Anbausysteme hat die Züchtung von Evolutionsramschen, die auf der Herstellung heterogener, evolvierender Composite Cross Populationen (CCPs) basiert, zunehmende Aufmerksamkeit geweckt. Die Vorteile solch genetisch vielfältiger Populationen umfassen u.a. flexiblere Reaktionen auf Stressfaktoren, die...

Different row distances (12,5 cm vs. 50 cm) and leguminous underseeds have nor-mally little effect on of grain crop yield. When the main crops are strongly influenced by weed a higher yield can be achieved with the help of the wide-row-system. The crop quality can also be improved, for example the baking performance of winter wheat. The higher preceding crop value of wide-row-system with underseed can be demonstrated by potatoes.

Autores: Siebrecht, Norman; Hülsbergen, Prof. Dr. Kurt-Jürgen.
Organic farming depends on the promotion of biodiversity and the corresponding  functions. Almost no tools are known for the purpose of farm-specific information  explaining the influence of farm management on biodiversity. The paper describes a  pressure indicator oriented approach that allows estimating such effects. It has been  applied in 2 organic and 2 conventional farms where results were discussed. The  investigations made so far allow concluding that multiple-structured low-input systems  achieve better marks than specialized high-input systems. For further development  and validation additional studies are required. It is planned to test the indicator model  in numerous farms, in order to disclose bottlenecks and deficiencies.

Das direkte Subventionszahlungsprogramm für eine umweltfreundliche Landwirtschaft in Südkorea
Provedor de dados: 21
Autores: Chang, Chul-Lee; Hoffmann, Heide.
Die aktuelle Agrarpolitik in Südkorea ist gegenwärtig darauf ausgerichtet, eine umweltfreundliche Landwirtschaft zu fördern. Dafür gibt es zwei Ursachen: Einerseits führt die intensive Landbewirtschaftung zu zahlreichen Umweltprobleme. Andererseits entstehen Betrieben, die umweltfreundlich produzieren Einkommensverluste durch eine geringere Produktivität. Be-sonders betroffen sind davon auch Betriebe des ökologischen Landbaus. Im Ergebnis der GATT-Verhandlung/Uruguay Round wurde Inlandsintervention mittels der Preisunterstüt-zung für die Agrarprodukte beschränkt (Seo et al. 1996).  Deshalb gehört zu den Maßnahmen der Förderungspolitik das Programm "Direkte Subventi-onszahlungen für umweltfreundliche Landwirtschaft" (MAFF, 2001; Lee, 1998). Dadurch sollen...

Das historische Konzept der Ornamented Farm als Vorbild für Landschaftsgestaltung durch den Ökologischen Landbau?
Provedor de dados: 21
Autores: Friede, Ute; van Elsen, Thomas.
The concept of “ornamented farms” originates in England. In the 18th century the landscape of many farms was developed to a way to combine functional aims with aesthetic issues. Groups of trees and biotopes like ponds, brooks or hedgerows were integrated into the farmed land, not for reasons of nature conservation but to combine a “modern” agriculture with a nice looking landscape or scenery.  The present investigation deals with the question weather these historical approaches are relevant for organic farms of today. Two examples of ornamented farms in Ger-many are discussed. Aspects of the historical “ornamented farm”-approach could be used to create concepts for whole farms that cover different measures to improve the impact of organic faming on...

In Germany, consumers are confronted with more than 100 organic labels, which lead to uncertainty about the reliability of such labels. As a solution, one public organic label, the Bio-Siegel, was designed. This raises two questions from the marketing perspective: (1) Do any of the individual organic labels have a specific image, a unique selling proposition (USP)? (2) Does the federal Bio-Siegel reduce consumer uncertainty with organic products? The overall objective of this study is to reveal and compare product profiles and preferences for organic labels at the German food market. 300 face-to-face interviews of consumers using a standardised questionnaire were conducted. The survey addressed the importance of organic labelling  compared to other...

Problems of machinery induced soil compaction are evident in organic vegetable production, resulting in stunted root growth and reduced yield. Controlled traffic farming (CTF) provides a possibility to restrict soil compaction to wheel tracks and create traffic-free vegetable beds with improved soil structure. A field experiment was established at a commercial organic vegetable farm in Denmark to investigate the effect of CTF on the growth of cabbage (Brassica oleracea), potato (Solanum tuberosum) and beetroot (Beta vulgaris). Random traffic farming (RTF) served as the  control. Preliminary results show that root intensity was higher in the CTF treatment compared to the RTF treatment for cabbage at the end of the growing season, indicating a better soil...

Das System der sogenannten Weideschlachtung/Kugelschuss auf der Weide ist bis dato einmalig in der Schweiz. In Deutschland wird die stressvermeidende Weideschlachtung schon auf mehreren Betrieben durchgeführt. Die Schlachtrinder werden nicht mehr dem Stress bedeutenden Verlust der vertrauten Umgebung ausgesetzt und können ohne Lebendtiertransport und den damit verbundenen Stressfaktoren auf dem heimischen Betrieb betäubt und getötet werden. Nach dem Entbluten wird der Schlachtkörper dann in einem eigens dafür angefertigten PKW-Anhänger, der sämtliche hygienetechnischen Anforderungen erfüllt, in ein nahegelegenes Schlachtlokal verbracht und dort fachgerecht und im konventionellen Sinne weiterverarbeitet. Damit das System der Weideschlachtung einwandfrei...

About eighteen percent of the conventional dairy and cash crop farmers in Norway are considering to, and four percent are planning to convert to organic farming during the next five years. These two farmer groups can be considered as the potential for conversion to organic farming in Norway. In a questionnaire survey, this group rated attitudes on organic and conventional farming more similar to organic farmers than other conventional farmers did. For farmers considering or planning to convert, additional organic farming payments, organic farming laws and regulations and price premiums for organic products were more important sources of risk than for other conventional farmers. Most of these mentioned factors are influenced by agricultural policies, which...

We aim to create an international network of farmers and scientists to jointly develop new and interdisciplinary approaches to health measurement and research in  ecological agriculture. First, to establish common ground, we identified personal principles and strategies of best practice that make organic farmers successful in  running healthy farm systems. Building on this practice experience and findings from a former research project (Vieweger &amp; Döring, 2015), we aim to produce a set of  transferable strategies to increase the direct translation of organic principles into practice and improve the understanding of health concepts in practice. For the  identification of example farmers in three countries (Austria, Germany, UK), we used an online...

Research institutes and universities of nine European countries are involved in the research project EcoOrchard to develop appropriate strategies to promote functional  agro-biodiversity in organic pome fruit production. Therefore field trials have been laid out at different sites in seven member states in 2015, where flower strips were sown into the inter-rows of the orchards. Natural antagonists like Syrphidae, Coccinelidae and parasitoids of codling moth are supposed to be promoted with these additional floral ressources. Besides faunal and floristic studies, practical methods and indicators have been worked out to monitor functional biodiversity.

Autores: Urselmans, Stefanie; Damme, Klaus.
In den vergangenen Jahrzehnten hat die Zucht auf bestimmte Leistungsmerkmale wie Fleischansatz oder Legeleistung zwei Linien aus dem einstigen Haushuhn hervorgebracht, das Masthähnchen und die Legehenne. Während beim Masthähnchen beide Geschlechter gemästet werden, wird bei der Legehenne das männliche Tier, da es keinen ausreichenden Fleischansatz zeigt, am ersten Lebenstag getötet. Dies trifft zunehmend auf rechtliche und ethische Bedenken. Aus diesem Grund wird seit Jahren nach Alternativen für diese gängige Praxis gesucht. Lösungsansätze liegen im Bereich der in-ovo Geschlechtsbestimmung, einer verlängerten Legeperiode oder der Züchtung neuer Hybriden, welche eine gute Legeleistung und einen akzeptablen Fleischansatz zeigen.

De la vulnérabilité au prestige? L’agriculture écologique et biologique, un outil de négociation et d’exercice du pouvoir des femmes

Autores: Delphine, Bodjrenou.
Les études en agriculture écologique et biologique montrent très peu d’intérêt aux questions langagières en général et celles des femmes en particulier en considérant à tort ou à raison les travaux linguistiques comme non adéquates en agriculture. Toutefois, la langue se trouve au cœur de toute discipline et c’est qui nous motive lorsque nous nous intéressons au discours de femmes qui s’investissent dans ce mode de production. Au Bénin, les femmes rurales sont au cœur des systèmes de production agricole où elles jouent des rôles primordiaux. Néanmoins, à l’heure de s’exprimer, elles sont reléguées au second rang et deviennent des invisibles et des sans voix. Ceci revient au fait que si la femme doit parler, étant la propriété privée d’un homme, cet homme...

Deconstructing the organic movement
Provedor de dados: 21
Autores: Frost, David.
This report was presented at the UK Organic Research 2002 Conference. Organic agriculture has sought to establish its scientific validity and its origins. Conford (2001) claims that these can be traced to the 1920s, and that Anglican Christianity is pivotal to its history. However, organic agriculture takes many forms and the role of religion in society has changed. In the UK, a new incarnation of organic farming occurred in the late twentieth century as part of a wider response to environmental issues.

Degradation behaviour of potassium K-phosphite in apple trees
Provedor de dados: 21
Autores: Kelderer, Markus; Matteazzi, Aldo; Casera, Claudio.
Although potassium phosphite is not registered for organic fruit production in Europe, it  has long been regarded as a potential alternative to sulphur- and copper-containing  fungicides. In 2005/2006 a field trial was carried out to verify the presence of residues of  phosphoric acid over time in apples after applications of potassium phosphite at different  time-points. No residues were present on fruits if treatments were applied before flowering,  whereas treatments after flowering, in the summer or in autumn resulted in comparable  residue levels irrespective of the period of application. Residues were eveneven found in  leaves and fruits of the following years, 2006 and 2007.

La séparation précoce mère-veau est une pratique courante dans la plupart des élevages laitiers, mais est sujette à de nombreuses interrogations tant chez les éleveurs (coûts engendrés, travail) que dans la société (bien-être animal). Des pratiques alternatives mises en place par certains éleveurs permettent aux veaux d'être allaités par leur mère ou une autre vache, appelée « nourrice ». Quoiqu’anciennes, ces pratiques demeurent peu connues et leur intégration aux conditions d’élevages modernes questionne.

Deliverable 1.3.(a): Conference paper: Consumer evaluation of imported organic food products in emerging economies in Asia
Provedor de dados: 21
Autores: Pedersen, Susanne; Aschemann-Witzel, Jessica; Thøgersen, John.
Consumers in emerging economies such as Thailand and China have started to demand organic food products – mainly due to food safety reasons (Ortega, Wang, Wu, &amp; Hong, 2015; Roitner-Schobesberger, Darnhofer, Somsook, &amp; Vogl, 2008; C. L. Wang, Li, Barnes, &amp; Ahn, 2012; O. Wang, De Steur, Gellynck, &amp; Verbeke, 2015). Since the domestic organic markets are still not well-established in Thailand and China, there is a huge potential for export of organic food products to these markets from countries, where the organic markets are more established and able to provide consumers with safe products. However, little is known about consumer preferences for imported organic food in emerging economies in Asia.     A total of 139 in-store interviews were...

Provedor de dados: 21
Autores: Pedersen, Susanne; Aschemann-Witzel, Jessica; Thøgersen, John.
In Germany, as in several other European countries, the demand for organic food is growing substantially faster than domestic production and supply, which has led to high import shares of many organic foods. Consequently, domestic consumers are presented with a wide variety of organic products from foreign country-of-origins (COOs).   Although there are many studies of consumer preferences for COO on the one hand and organic food on the other, research on COO effects in the context of organic food is scarce. More specifically, there is a lack of research on how consumers evaluate imported organic food products.  To explore regional differences in German consumers’ preferences for imported organic foods, 6 focus groups and 255 in-store interviews were...

Demonstration Centres for Sustainable Agriculture
Provedor de dados: 21
Autores: Znaor, Darko.
The urge for more sustainable agriculture is increasingly recognized by the various parts of society (producers, consumers, scientists, policy makers, etc.). But in order to realize sustainable agriculture in practice it is not sufficient to change only the on-farm agricultural practices. Present socio-economic and political paradigms also need a change so that these can be able to support implementation of sustainable agriculture.     The concept of Demonstration Centres for Applied Agricultural Sustainability (DCAAS) offers an interesting concept and operative tool for changes not only at the farm level. Well designed and professionally organized DCAAS don't have a potential to demonstrate only "excellence" of sustainable agricultural production in...

Den danske dyrkningsjords tilstand og kvalitet - konsekvenser af trafik og jordbearbejdning
Provedor de dados: 21
Autores: Schjønning, P.; Munkholm, L.J.; Elmholt, S.; Debosz, K.; Mikkelsen, G.H.; Trautner, A.
Et alsidigt sædskifte og/eller tilførsel af organisk stof til jorden giver en god jordkvalitet (her defineret som en gunstig jordstruktur). Ensidige driftsformer kan i sig selv give anledning til en dårlig jordkvalitet. Jordpakning via trafik på jorden kan eliminere de gode effekter af et godt sædskifte og tilførsel af organisk stof.   Trafik på jorden og i endnu højere grad intensiv jordbearbejdning øger risikoen for, at jordens lermineraler dispergeres til vandfasen. Dette kan give tilslemning og skorpedannelse på jorden og indebærer endvidere en risiko for nedvaskning af de vigtige lermineraler fra dyrkningslaget. Der bør foretages undersøgelser af omfanget af denne proces med de i dag anvendte bearbejdningsteknikker.   Komprimering af jorden under...

Den langsigtede effekt af kløvergræsgrøngødning og efterafgrøder på udviklingen af kvik og tidsler
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Thomsen, Henning C.; Askegaard, Margrethe; Olesen, Jørgen E.
Kløvergræs opformerer kvik, men reducerer tidsler. Efterafgrøder opformerer kvik, men ikke tidsler, sammenlignet med stubbearbejdning. Når man har problemer med rodukrudt, er det vigtigt at forstå, hvordan sædskifte og andre kulturforanstaltninger påvirker rodukrudtet, både på kort og langt sigt. Desværre findes der kun få data for den langsigtede effekt af kløvergræs som grøngødning og efterafgrøder på rodukrudt. I det økologiske sædskifteforsøg (Askegaard et al. 2004), som blev anlagt i 1996, har vi fulgt udviklingen af især kvik og tidsler frem til nu, og det giver os mulighed for at udtale os om betydningen af de forskellige faktorer.

Density, structure and management of landscape elements on Danish organic farms
Provedor de dados: 21
Autores: Frederiksen, Pia; Langer, Vibeke.
Density and management of landscape elements on organic farms were investigated for 345 organic farms in Denmark in 2001, representing approximately 10% of the total number of organic farms. The density of hedgerows, area habitats and ponds was estimated and related to various aspects of farm character, such as size, type and lifestyle/part time/full time farms, as well as region and biophysical context. A large variation in the densities was found, the highest densities were found on the smallest farms. Farm size was the farm parameter that was closest related to the density of landscape elements as well as landscape structural variables. Farm size was related to the other farm characteristics.

Dependence  of organic vegetable production on conventional seeds: are we ready for emancipation?
Provedor de dados: 21
Autores: Micheloni, MSc Cristina; Roviglioni, MSc Raffaella.
The organic system is urging the use of organic seeds in order to complete its integrity  and  enhance its reliability. The VIFP Organic Revision offered the possibility to investigate on the different issues related to organic seeds production and use: alternative seed treatments methods; variety availability; derogation regime in several EU Member States and causes for non-use of organic seeds. The results indicate the extreme difficulty the organic vegetable sector will suffer in case it is decided to stop the derogation regime and compell producers to use exclusively organic seeds.

DEPENDENCE ON AGRICULTURAL TRADE IN TURKEY
Provedor de dados: 21
Autores: Acar, Sevil.
This study is an attempt to show the dependence on agricultural trade in Turkey focusing on the import coverage of exports calculated by “exports divided by imports” in percentages. As such, one can easily see whether a country relies on exports or imports of a specific product or product group. Besides, export value of organic products will be displayed in a separate graph. Since organic imports are very limited, import coverage of organic exports has not been calculated due to lack of data.

Der Anbau von Linsen und Erbsen im Gemenge
Provedor de dados: 21
Autores: Boland, E.; Zikeli, Sabine; Gruber, S.
In Germany, lentils (Lens culinaris) are traditionally grown in mixture with cereals to reduce lodging and weed pressure. To test semi-leafless pea (Pisum sativum) as an alternative companion crop instead of dwarf oat (Avena sativa), a field trial was conducted in 2015 at the organic research station of the University of Hohenheim, south-west Germany. The three crops were cultivated in pure stands and in ratios of  1:3, 1:1 and 3:1 (lentil : pea or oat). Focus was on comparing lodging resistance, weed suppression, and grain yield. Lodging was low in all mixtures but high in lentil pure stands. Yields were very high for lentils and peas but rather low for oats (3.2 t ha-1, 4.9 t ha-1, and 3.2 t ha-1, in pure stands). Similarly, high lentil yields were...

Ammonia emissions are an important problem in agricultural systems. Organic pig production raises a claim to offer high animal welfare. However, gaseous emissions can exhaust out of outdoor runs. Many measurement technics to determine the ammonia volatilization in animal facilities exist. In outdoor runs it is necessary to define the air volume flow. In addition, the contaminated surface of the pig-yard is heterogeneous. Therefore, it is interesting if the ammonia concentration correlate with the amount of manure. The outdoor run has been divided in a matrix. The ammonia concentrations are determined with a multi-gas monitor (INNOVA 1312) in combination with a dynamic chamber. The study showed a difference in ammonia volatilization between roofed and...

Autores: Fischerleitner, Franz; Berger, Beate; Atteneder, Veronika.
The Austrian gene conservation programme for rare breeds from 2001 to 2006 re-sulted in increasing numbers of participating farms as well as increasing numbers of animals. On the whole the programme was readily accepted and successfully realized by the farmers. The percentage of participating organic farms lies with 41% signifi-cantly above the average as only 10% of all farms are organic farms. Further the number of breeding animals in the gene conservation programme proves the en-gagement of the farmers. On organic farms 11,804 animals (44%) are in use against 15,126 animals (56%) on conventional farms in 2006. However with 6.4 animals/farm the average number of animals per organic farm is a little higher than on commercial farms (5.6 animals/farm). 9%...

Der Beitrag des Biolandbaus zu einer territorialen Entwicklung
Provedor de dados: 21
Autores: Schermer, Markus; Kirchengast, Christoph.
The ongoing changes from an agricultural to a rural society force farmers to redefine their positions – regarding social as well as economic aspects. Organic agriculture provides a value system which is well accepted by non-agricultural rural stakeholders and can therefore be a potential starting point for territorial sustainable development. In Austria the approach of eco-regions (Bioregionen) provides such an approach. The paper gives some preliminary results on the preconditions necessary for the estab-lishment of such an approach building on the results of an ongoing national project.

Autores: Schaub, Dagmar; Paulsen, Hans Marten; Böhm, Herwart; Rahmann, Gerold.
Only few long-term trials under temperate climate analyse the effect of different crop rotations. To compare various crop rotations (two cash crop and three livestock farms) under the same site conditions the long-term monitoring Trenthorst was established in 2003. A detailed description of the study is given in SCHAUB et al. (2007). The follow-ing paper presents the yields of three farms (dairy, cash crop and mixed) for the years 2003 to 2005. The dairy and cash crop farm obtained similar average yields, whereas the yields of the mixed farm were lower. This can be attributed to more inhomogene-ous fields and to the oil crops in the rotation of the mixed farm, which led to a lower yield potential of the rotation and to weed problems.

The long-term monitoring Trenthorst was established in 2003 and comprises the different crop rotations of two cash crop farms and three livestock farms specialised in dairy, pigs and goats/oil seeds respectively. In addition to the comparison of crop rotations under practical farm conditions the long-term monitoring study aims to analyse the development of soil parameters, yields and crop qualities after the conversion to organic agriculture. On each arable field four monitoring points were established, where the relevant parameters are measured. The yields of the first three years are...

Der kontinuierliche Rückgang der Landwirtschaftsfläche in der Schweiz führt dazu, dass die verbleibenden Flächen bei einem jährlichen Einsatz von 2200 t Pestiziden zunehmend intensiver und in grösseren Einheiten bewirtschaftet werden. Die heute dominierenden, an Blütenpflanzen und Kleinstrukturen armen «grünen Wüsten» bieten kaum noch Nahrung für Honigbienen.  Der intensive Einsatz von Pestiziden und die geringen Nahrungsressourcen schwächen die Honigbienen. In Verbindung mit einem Befall durch die Varroa-Milbe kann dies zur Erkrankung der Bienen und zum Tod ganzer Völker führen.

Agricultural intensification (AI) negatively affects biodiversity due to e.g. high-input farming. Organic farming can counteract this negative trend. Here, we studied  movement behavior of the European brown hare (Lepus europaeus), which frequently occurs in agricultural landscapes but also suffers from AI with declining population densities. We measured home range sizes in relation to local field management (organic vs. conventional farming) in Upper Bavarian, Germany. Results showed that  home ranges sizes decreased with increasing amount of organically managed area, while there was no relationship between conventional farmed area and hares’  movement behavior. Higher resource availability in organic fields decrease home range sizes and may therefore...

In the present study, AMF root colonisation of potato plants was compared between organically and minerally fertilised field plots, which did not significantly differ in the total amount of plant available P. The AMF root colonisation was increased in response to organic fertilisation. This indicates that organic fertilisation can enhance AMF development independently from the soil P fertilisation level. Furthermore, soil grown mycelium was trapped in fungal compartments. This technique allowed the extraction and quantification of coarse and finely branched soil grown hyphae after harvest. The soil in the fungal compartments was either fertilised with low or with high amounts of mineral P. In organically fertilised field plots, the amounts of finely...

To increase nutrient use efficiency and reduce nutrient losses are key aspects for sustainable agriculture. Arbuscular mycorrhizal fungi (AMF) are an import and widespread group of plant-symbiotic soil fungi. Here we investigate the role of those soil microorganisms, for effective nutrient recycling. We conducted greenhouse and lysimeter experiments to compare the cycling of important plant nutrients in systems with high and low abundance of AMF. AMF increased plant N nutrition, reduced leaching losses of mineral N, and prevented emissions of N2O, an important greenhouse gas. The results show the importance of AMF for an effective nutrient management. Farmers should implement strategies to promote AMF in the soil, as they are an indispensable compound of...

Genetic correlations between milk yield and different fitness traits were estimated in Fleckvieh and Brown Swiss cattle. These updated correlations were taken into  account in the calculation of an organic total merit index (ÖZW), where the fitness traits have larger weight than in the conventional total merit index (GZW). As a  consequence, the relative theoretical selection response in functional traits (18-23%) was higher and the selection response in milk yield was lower than before. This index  is therefore more suited for the ecological breeders but may also implicate that biological and conventional breeding goals will drift apart. To ensure that in the long term suitable bulls for biological farms will be available, AI  stations will have to...

Plant parasitic nematodes (PPN) can be highly damaging towards plants managed organically. In particular, broad host range PPN (Pratylenchus spp., Meloidogyne spp.) increase under long crop rotations and high weed pressure. PPN populations have been monitored since the beginning of an EU-project about minimum tillage, cover crops. living mulches, and compost application in organic farming in 2012. In the first two years after set up of the experiment, a slight increase of PPN in the minimum tillage treatment was found. However, compost as well as cover crops and living mulches did not change PPN populations so far.

Conservation agriculture is one answer to counteract problems that are arising with climate change and soil degradation since the period of agricultural intensification. The main objectives of conservation agriculture are reduction of tillage intensity and a  permanent soil cover by cash and cover crops. However, increased weed infestations are frequently reported in minimum tillage systems, particularly under organic  management, resulting in increased weed seed banks.  In two field experiments introduced in 2010 and 2011 and starting with two years grass-clover followed by winter wheat and potatoes, we evaluated the effect of chisel  ploughing with mulch application to potatoes and different cover crops after winter wheat on the weed seed bank....

Reduced tillage and green manures may be capable to further improve organic crop production systems. However, it is presumed that under organic farming conditions a lower intensity of soil tillage may reduce nitrogen (N) availability and increase weed pressure. A combination of reduced tillage with an appropriate green manure species could answer these problems.  The results of a repeated one year trial on the research farm of University of Kassel, regarding the effects of three different green manure species (Sinapis alba, Trifolium resupinatum and Vicia sativa) and conventional (plough) vs. reduced tillage (2012 chisel, 2013 disc harrow) on N availability in spring and on the yield of main crop oat are the topic of this paper.  In both years, in the...

Der Möhre einen Namen geben – Sortenvermarktung von Gemüse – ein innovatives Konzept auf der Grundlage eines erweiterten Qualitätsbegriffs
Provedor de dados: 21
Autores: Boie, Petra; Fleck, Michael.
Ausgangspunkt des Projektes war vor vier Jahren die durch z.B. das FIBL-Dossier „Pflanzenzüchtung“ unterstützte These, dass die Methoden der konventionellen Pflanzenzüchtung sich immer weiter von den Praktiken entfernen, die für den Ökologischen Landbau und die Biologisch-Dynamische Wirtschaftsweise geeignet angesehen werden. Die Kritik bezieht sich sowohl auf die angewandten Techniken als auch auf die Reduktion der Sorten auf bloßes Wirtschaftsgut. Unter dem Dach des Vereins Kultursaat werden Gemüsesorten entwickelt, die in qualitativer, sozio-ökonomischer und ethischer Hinsicht den Prinzipien des Ökologischen Landbaus entsprechen (z.B. Participatory Plant Breeding). Da die o.a. Lage sich mit zunehmender Ausbreitung der Gentechnik verschärft, bei allen...

Öko-Geflügel hat das Potenzial, die steigende Nachfrage der Verbraucher nach ökologisch und tierfreundlich erzeugtem Fleisch zu befriedigen. Der Marktanteil von Öko-Geflügel ist jedoch nach wie vor gering. Basierend auf Primärdaten von 644 Verbrauchern haben wir die Verbraucher entsprechend ihres Kaufs von Geflügelprodukten in drei Segmente eingeteilt: diejenigen, die nur Öko-Geflügelprodukte kaufen, diejenigen, die nur konventionelle und diejenigen, die konventionelle sowie Öko-Geflügelprodukte kaufen. Wir haben Unterschiede zwischen den Segmenten und Determinanten für den Kauf von Öko-Geflügelprodukten mit Hilfe von deskriptiven Statistiken, explorativer Faktorenanalyse und einem multinomialen Logit-Modell analysiert.

Der Öko-Landbau als Objekt der Politik
Provedor de dados: 21
Autores: Dabbert, S.
Organic farming has been developed by a social movement without government support and intervention. This situation  changed in the EU during the last decade since around 1990 when subsidies for organic farmers were introduced, the defining power on the term „organic farming“ was taken over by the European Commission, and a system of government led certification and control has been established. The paper argues that this has been an unavoidable development whose consequences have not yet been fully understood neither by the organic farming sector itself, nor by the government authorities involved. It is suggested that the organic sector strongly increases its lobbying activities and that the European Commission adopts a more unified policy approach to...

Der Ökologische Gesamtzuchtwert für Fleckvieh, Braunvieh und Gelbvieh
Provedor de dados: 21
Autores: Krogmeier, D.
Der ökologische Gesamtzuchtwert (ÖZW) ist ein Gesamtzuchtwert, der der Zuchtzielsetzung in der ökologischen Milchviehhaltung entspricht. Der ÖZW stellt eine „ökologische Reihung“ der aktuellen Besamungsbullen dar und ist ein wichtiges Hilfsmittel für die Zuchtarbeit im ökologisch arbeitenden Milchviehbetrieb.   In den Ausführungen wird der ÖZW in seinen Einzelheiten beschrieben und aufgezeigt, dass ein ökologischer Zuchtwert nicht mit einem ökologisch orientierten Zuchtprogramm gleichzusetzen ist. Ein solches Programm ist aufgrund der geringen Anzahl von Herdbuchkühen in ökologischen Betrieben nicht durchführbar. Eine Beteiligung am bestehenden Zuchtprogramm ist bereits über Paarungsempfehlungen realisiert und sollte weiterentwickelt werden.   Wenn es...

Zusammenfassung  Analog zum Ökologischen Gesamtzuchtwert (ÖZW) für Bullen wurde Ende 2008 erstmals ein ÖZW für Kühe berechnet und den ökologischen Milchviehbetrieben in Bayern mit dem Jahresabschluss der Milchleistungsprüfung zur Verfügung gestellt. Der ÖZW unterscheidet sich vom konventionellen Gesamtzuchtwert (GZW) hauptsächlich durch die deutlich stärkere Gewichtung der Fitnessmerkmale. Während bei der Zucht nach GZW der erwartete Selektionserfolg überwiegend in der Milch- und Fleischleistung liegt, wird bei der Selektion nach ÖZW, neben einer moderaten Verbesserung der Leistung, eine deutliche züchterische Verbesserung der Fitnessmerkmale angestrebt.  Der ÖZW für Kühe sowie die Teilzuchtwerte Leistung und Konstitution ermöglichen dem ökologisch...

In northern America on-farm research has been successfully performed for many years either by the farmer himself or with the support of extensions. Accordingly, many written guides on how to carry out on-farm research are available. The opportunities of the internet can be used to guide the practical user with his decisions better than written guides can do. Furthermore, so called online guides may support the user with statistical analysis tools and be of help improving the knowledge exchange between scientists and people in practice. In this contribution the first online guide for on-farm research is outlined in its basics.

Autores: Häring, D.A.; Suter, D.; Lüscher, A.
Depending on the concentration in which they are fed, condensed tannins (CT) can have various beneficial or detrimental effects on ruminants. In organic farming the anthelmintic effects of CT are of special interest. In an outdoor experiment, the sea-sonal dynamics of the CT concentration of the harvestable biomass was investigated as a function of the biomass allocation to leaves and stems in Onobrychis viciifolia, Lotus corniculatus and Cichorium intybus in the course of a vegetation period in Zu-rich, Switzerland. Such knowledge is indispensable for a practical application of tan-niferous plants in farming systems. In line with our expectations, CT concentrations were higher in leaves than in stems and the leaf fraction of the harvestable biomass...

Der Stoppelhobel – eine Alternative zu herkömmlichen Geräten der Stoppelbearbeitung im Ökologischen Landbau?
Provedor de dados: 21
Autores: Hunger, Stefan; Pekrun, Carola; Claupein, Wilhelm.
Before introduction of herbicides shallow ploughing was a widespread method of stubble tillage. In June 1999 25 trials on 7 organic farms were set up in South Germany. Three treatments of stubble tillage were compared: 1. “Stoppelhobel” (shallow ploughing); 2. “non inversion” stubble tillage (mostly chisel); 3. “control” (no stubble tillage). Results are shown for the first 16 months after initiating the experiments. In spring 2000 significant differences were assessed between the treatments “control” on one hand and “Stoppelhobel” and “non inversion” on the other with respect to perennial weeds. The same results were recorded on the stubble 2000. For annual weeds treatments never differed significantly. Yields showed no significant differences in most...

Der Trockenmassegehalt der Kartoffelknollen als Indikator für den Ausreifungsgrad der Knollen und der relativen Bedeutung des Krautfäulebefalls
Provedor de dados: 21
Autores: Möller, Kurt.
Fazit: Aus den vorgestellten Ergebnissen kann abgeleitet werden, dass die Kartoffeln zunächst Knollen mit relativ geringen Trockenmassegehalten anlegen. Nach der Knollenanlage steigen die TM-Gehalte der angelegten Knollen kontinuierlich an. Ein deutlicher Anstieg ist auch noch in den ersten (ca. 5-10) Tagen nach Beendigung des Knollengrößenwachstums - während der beginnenden Abreifephase - festzustellen. Daher “reagieren” die TM-Gehalte der Knollen sehr viel „empfindlicher“ auf einen Krautfäulebefall (durch Verminderung der Gehalte) als die Knollenerträge. Zugleich wird mit steigender N-Versorgung der Beginn der Abreife eines Kartoffelbestandes (= Ende des Knollengrößenwachstums) zeitlich verschoben, dies bewirkt ebenfalls eine Verzögerung des Anstieges...

Der Vorteil von Stallmist gegenüber pflanzlichem organischem Dünger für den Ertrag von Rotklee und den Humusgehalt des Bodens
Provedor de dados: 21
Autores: Raupp, J.; Jarosch, A.-M.; Oltmanns, M.
Die Wirkung pflanzlicher organischer Dünger (meist Leguminosenschrot) wurde bislang vorwiegend im Jahr der Anwendung, aber nicht als Langzeiteffekt auf Erträge und Bodenentwicklung untersucht. Ein direkter Vergleich mit Stallmist unter Feldbedingungen findet in der Regel nicht statt. Deshalb haben wir in einem Langzeitversuch (seit 1996) Stallmistdüngung, organische Dünger pflanzlicher Herkunft (meist Ackerbohnenschrot) und Mineraldüngung miteinander verglichen. In allen drei Schnitten brachte die Nachwirkung der pflanzlichen Dünger niedrigere Frisch- und Trockenmasse-Erträge als die N-gleichen Stallmistvarianten. Der Ertrag nach Mineraldüngung lag zwischen den beiden anderen Düngerarten, kam aber der Mistvariante meist näher als der Ackerbohnenvariante....

Since 1980 a long-term experiment has been carried out to compare mineral fertilizers (MIN), composted manure (RM) and composted manure with application of biodynamic preparations (RMBD) at three different fertilizer application rates. The total C and N contents in the topsoil were significantly different between all three fertilizer types. 42.9 to 53.7 % of Nt was bound in 18 total hydrolysable protein amino acids (THAA) including asparagine and glutamine. Amino acid contents in the hydrolysates of the topsoil were significantly different according to fertilizer type: MIN &lt; RM &lt; RMBD. The higher contents in manure fertilized plots were observed even at the lowest rate of fertilizer application. This indicates that differences between the treatments...

Drying is an energy and time intensive process which thermal energy demand is mostly provided by fossil resources. Especially in the food processing industry it is important to increase the energy efficiency of drying processes in terms of organic products and sustainability. The potential of using a heat pump with R744 (CO2) as a working media to provide the thermal energy was investigated for typical food drying temperature of 50 °C at a relative humidity of 20 %. A dynamic heat pumpassisted dryer model has been developed and validated. The model was created with respect to heat transfer, pressure loss and flow requirements. The simulated results showed that a closed-loop heat pump assisted drying process has the potential to reduce the energy demand by...

Autores: Ranaldo, Marzia; Carlesi, Stefano; Costanzo, Ambrogio; Bàrberi, Paolo.
Cover crops play a key role in weed management strategy in no-till organic and low input vegetable systems. The ability of cover crops to reduce weed pressure can be  linked to the amount of biomass produced at the time of cover crop devitalisation. Cover crop mixtures, in particular functional diversity in cover crop mixtures, can be managed to improve biomass production and weed suppressive ability of cover crops. We tested eight cover crop species pure stands and designed nine cover crop mixtures at increasing levels of functional diversity. The aim of this study was to highlight the effect of cover crops' functional diversity in controlling weeds before aubergine (Solanum melongena L.) transplanting. We showed that the functional composition (i.e. the...

Species-rich swards have received increasing interest due to their focus on ecosystem services, animal welfare and product quality. However, in high-yielding swards the proportion of herbs is often limited and there is little knowledge of their management. Seed mixture composition, cutting frequency, fertilization and grazing/cutting strategies were examined over 4 years in 3 experiments to quantify their effects on herbage yield and botanical composition. Inclusion of herbs in the sward gave similar or higher annual yields but swards established with 100% herbs depended on the presence of a driver species. The  effects of management differed between species. Herb content in the sward was significantly related to the proportion of herbs in the seed...

The necessary ecologization of agriculture in the developed countries has recently resulted in the research of innovative systems that are both economically viable and environmentally friendly, with sustainable objectives at mid and long terms. The sylvoarable systems, mixing trees and crops on the same plot, are ecologically intensive systems that allow a better use of natural resources, hence increase production on the same land area. The vegetable orchard is a sylvoarable system mixing fruit trees and vegetable crops that disappeared in the 1950’s for economic reasons.

I dag kan man emellertid inte bilda en fullständig helhetsbild av ekologins kommande utveckling. Det är oerhört svårt att på lång sikt uppskatta den gemensamma effekten av hur marknadens, de politiska systemens, standardernas och konsumenternas värderingar utvecklas. Det ser dock ut att den nuvarande trenden i EU:s gemensamma jordbrukspolitik gynnar ekologin. Att separera stödet från produktionen samtidigt som producentprisnivån sjunker gynnar i princip det ekologiska produktionssättet, där det är möjligt att minimera de rörliga kostnaderna som beror på inköpen. Men hur det egentliga stödet för ekologin ser ut i kommande jordbrukslösningar har naturligtvis en stor betydelse.

The fatty acid (FA) composition of bovine milk may be related to human health and technological properties of dairy products. The FA composition can be altered both through management and breeding. Large scale FA profiling of the Danish dairy cattle population has now been implemented for more than a year. For the first time access to millions of FA observations across an entire dairy population enables in depth analysis of the factors affecting the FA profile of milk. This was the aim of this study. For 12 months more than 3.5 million milk samples from four Danish dairy breeds had been analyzed using mid infrared spectroscopy and application of FOSS Application Note 64 for predicting content of seven FA groups and four individual FA.

Autores: Poulsen, Nina Aagaard; Hein, Lisa; Gregersen, Sandra Beyer; Sørensen, Lars Peter; Larsen, L.B.; Kargo, Morten; Buitenhuis, Albert Johannes.
Abstract  Milk fatty acid (FA) composition can be manipulated through feeding, and especially effects of grazing have been shown to promote a healthier milk FA profile due to increasing contents of beneficial FAs, like conjugated linoleic acid (CLA) and α-linolenic acid (C18:3, the main n3 FA in milk). In addition to diet-based manipulations, selective breeding for specific FA could also be a strategy for altering the FA profile as milk FA display low to moderate heritabilites (0.07-0.34 in Danish Holstein).  Since 2015, milk samples from all Danish dairy cows under yield control have been analyzed using mid infrared spectroscopy. The FOSS Application Note 64 has subsequently been used to predict content of seven FA groups (short-chain FA (SCFA),...

Provedor de dados: 21
Autores: Feng, Xinmei; Passoth, Volkmar; Schnurer, Johan.
Tillväxt av mögel och jäst är ett problem vid lagring av spannmål ensilage och andra fodermedel. Traditionella metoder för identifiering och kvantifiering av sådana mikrosvampar är tidskrävande och mödosamma. Det finns därför ett behov för att utveckla nya, snabba och pålitliga förfaranden för identifiering och kvantifiering. Vi har utvecklat en molekylär metod som kan används för kvantifiering av mögel och jäst som växer på spannmål eller andra fodermedel. Förfarandet är baserat på direkt isolering av mikroorganismernas DNA från spannmål och kvantifiering av organismspecifika gener med realtids-PCR. Metoden utprovades i ett projekt för odling av mycelväxade svamp (Rhizopus oligosporus) och jäst (Saccharomyces cerevisiae) på korn. En enkel DNA-extraktion...

Autores: Meier-Dinkel, Lisa; Mörlein, Daniel; Bussemas, Ralf; Höinghaus, Kathrin; Weißmann, Friedrich.
Die Mast intakter männlicher Schweine birgt das Risiko des sogenannten Ebergeruchs, welcher problematisch für die Konsumentenakzeptanz ist. Die Praktikabilität der Ebermast hängt daher von der Reduktion der ursächlichen Substanzen im Tier sowie der sicheren Detektion auffälliger Schlachtkörper am Band ab. Zugabe von roher Kartoffelstärke verringerte die Rate geruchsauffälliger Schlachtkörper. Die Übereinstimmung zwischen den chemischen Messwerten und der humansensorischen Beurteilung lag bei 84 %.

Determinanten der Nachfrage ökologischer Lebensmittel
Provedor de dados: 21
Autores: Buder , Fabian; Hamm, Ulrich.
This paper deals with the question of the psychographic and socio-demographic factors influencing the purchase behaviour for organic food. Based on purchase data from household panels a causal model was developed and tested using the structural equation modelling method with SSI LISREL. The analysis revealed new insights about consumer behaviour regarding organic food. While the influence of the classical consumer segmentation criteria ‘income’ and ‘education’ was proven to be not significant, the purchase behaviour was primarily determined by selfish buying motives. Consumers buy organic products because they taste better, contain fewer residues and are considered to be healthier. In opposite, the influence of altruistic buying motives regarding...

Determinants of economic growth in organic farming: the case of Bavaria and Baden-Württemberg
Provedor de dados: 21
Autores: Brenes Muñoz, Thelma; Lakner, Sebastian; Brümmer, Bernhard.
Der vorliegende Beitrag untersucht Faktoren, die möglicherweise einen Einfluss auf das wirtschaftliche Wachstum von 332 ökologischen Betrieben in Bayern und Baden-Württemberg haben. Die Ergebnisse zeigen, dass Direktvermarktung und der Tierbesatz das einzelbetriebliche Wachstum positiv beeinflussen. Diese Effekte sind deutlicher ausgeprägt als andere Einflüsse. Daneben kann gezeigt werden, dass technisch ineffiziente Betriebe stärker wachsen als technisch effiziente Betriebe. Dies kann mit dem ökonomischen Druck auf ineffiziente Betriebe und mit Ineffizienz im Wachstumsprozess erklärt werden.

Determinants of Spatial Distribution of Organic Farming in Germany
Provedor de dados: 21
Autores: Bichler, Barbara; Haering, Anna Maria; Dabbert, Stephan; Lippert, Christian.
The share of organically managed land is spread unevenly throughout Germany and shows pronounced regional concentrations. The spatial distribution of organic farming is assumed to be influenced by several factors. Location factors of farms are regionally different and thus may influence the spatial distribution of organic farming. Agglomeration effects and therefore spatial dependence are also considered important in determining spatial distribution.   These factors with a potential influence on the spatial distribution of organic farming can be divided into four categories: natural factors, farm-structure factors, socio-economic factors and political factors. Their possible influence on the spatial distribution of organic farming is analysed by several...

Provedor de dados: 21
Autores: Mogoi, Kenyanya Teresa; Moturi, Wilkister Nyaora; Nyaanga, Jane; Macharia, Joseph Kinyoro; Birech, Rhoda Jerop.
Pesticides are used to protect crops from diseases and pests. Their application in agriculture has been in existence since ancient times to date. They have also been used in growing vegetables especially exotic vegetables that are more prone to pests and diseases. There have been concerns over indiscriminate use of pesticides by farmers to grow vegetables especially for local markets since there are no guidelines on Maximum residue levels. This study was done to determine the concentration of cypermethrin and lambda-cyhalothrin pesticide residues in Collard (Brassica oleracea var. acephala) Tomatoes (Solanum lycopersicum) and swiss chard (Beta vulgaris subsp. cicla). The samples included both organic and conventional vegetables that use chemical...

Autores: Han, Eusun; Dresbøll, Dorte Bodin; Thorup-Kristensen, Kristian.
Introduction: Deep roots have the potential to exploit plant resources otherwise inaccessible. The aim of this study was to develop a method, the Core-Labelling Technique (CLT), to measure root activity down to 2.5 m of soil depth under field conditions.     Materials and Methods: Two stainless steel ingrowth-cores, 0.1 m in diameter and 0.55 m in length, were filled with soil labelled with nutrient tracers, i.e., LiCO3, CsCO3, Na2SeO4, RbCO3 and 15NH4Cl. The labelled cores were placed into an access-tube having openings at 1.0 m and 2.5 m of soil depth. They were kept under a lucerne (Medicago sativa) crop for 60 days, after which, the root length density (RLD) and concentration of tracers in shoot biomass (including a control) were measured.    Results:...

Autores: Wolf, Birge; Szerencsits, Manfred; Gaus, Hansjörg; Müller, Christoph E.; Heß, Jürgen.
The evaluation of research beyond scientific impact is increasingly required, but has not yet been widely applied. One reason is that data necessary for the evaluation of the societal impact of science are often not available in sufficient quantities or suitable form. This paper describes first results from a research project that develops improved documentation to serve evaluation beyond scientific impact. Firstly, we refer to the need to do this, and to the specific challenges for data assessment in this area. Secondly, we describe the concept for documenting achievements of research beyond scientific impact with a research information system that integrates the relevant parts of research proposals and reports. This enables data to be provided without...

Autores: Jones, H; Clarke, S M; Haigh, Z; Hinchsliffe, K; Wolfe, M S; Thomas, J; Gibbon, D; Harris, F; Lyon, F.
The performance of UK winter wheat varieties was tested under organic conditions involving farmer participation. Three breadmaking varieties (Hereward, Solstice and Xi19) and their mixture (1:1:1) were grown at 19 UK farms in 2003/04 and 2004/05. The variability of productivity on organic farms was illustrated with more variation among farm sites than among varieties. Seed health was generally high over all sites. Although the trials were successful, more time was needed at project initiation to improve farmer involvement. Some farmers expected more researcher visits, and were reticent about assessing the trials themselves. In contrast, some participants valued the variety performance data on their farms particularly when related to that of other growers....

Developing a Strategy for Sustainable Improved Soil Productivity in the Tropics - Efficient Management of Crop Residue/Farm Waste
Provedor de dados: 21
Autores: Odion, Ehiabhi Cyril; Ibrahim, Usman; Sambo, Banake Elisha; Ahmed, Adamu; Mukthar, Aisha.
Harvest index, which measures the economic harvest of a crop, often refers to that part of a crop representing that which can be eaten or sold to others for consumption; in smallholder farming. The remainder of the crop, referred to as crop residue; is either fed to livestock, used to build fences, used as mulch, ploughed in (where such equipments are available) or burnt in small-scale farming, causing environmental pollution. These crop residues are also rich in nutrients that were extracted from the soil, used in the building of the edible parts and contribute to soil mining if not returned to the soil. This is a major bottleneck among smallholders as harvesting could take place when the soil is too dry to turn easily or they may not have the labour to...

Developing Energy Plants for Biofuels Production may Comply  to Organic Principles
Provedor de dados: 21
Autores: Akinyemi, Okoro Monday; Høgh-Jensen, Jensen.
Biofuels are the only source of renewable environmentally friendly fuel currently suitable for road transport without any negative traits associated with traditional biodiesel or other green energy alternatives. The combustion of petrol and diesel produces many different types of local air  pollutants, but the use of biofuels may result in the reductions in emissions of greenhouse gas carbon dioxide up  to 70%. Impacts on land use require careful planning to maximise the gains and minimise the losses. The role of biofuels in organic farming will solve three significant problems: 1) waste will become valuable resources; 2) low quality forage products can be utilized for biofuels and thus get value-added; and 3) the trafficable damage on soil fertilities...

Developing modern multifunctional agroforestry systems for sustainable intensification
Provedor de dados: 21
Autores: Smith, Jo; Pearce, Bruce; Döring, Thomas F.; Wolfe, M S.
Agroforestry is a land-use system that integrates trees and shrubs with crops and/or livestock production. It has been identified by the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD, 2008) as a ‘win-win’ approach that balances the production of commodities (food, feed, fuel, fibre, etc.) with non-commodity outputs such as environmental protection and cultural and landscape amenities. This paper will review the potential of agroforestry as part of a multifunctional working landscape in temperate regions, and will consider management and policy implications of widespread adoption of this form of land-use.

Organic Agriculture is present in 160 countries. All of them have developed differently and have different situations. The Organic World is organized in a decentralized way. It emphasizes local solutions to local challenges and prefers short chains of local production and consumption to globalized supply chains. While some countries have fairly well-developed and advanced Organic Sectors, others have just started. Governments and development actors increasingly realize that Organic agriculture provides ample opportunities to implement rural development agendas and national policies. Some countries have well-balanced Organic Movements that drive the development of the sector, while actors in other countries remain isolated or even compete with each other in...

Autores: Keatinge, Ray; Jackson, Frank; Kyriazakis, Ilias; Cork, Susan A.
This report was presented at the UK Organic Research 2002 Conference. Organic farmers have taken a lead in attempting to reduce dependence on pharmaceutical control of parasites in farmed livestock. Focussing on management and nutrition, the objective of this research is to further develop control strategies, which can support and increase the flexibility of clean grazing systems for sheep and cattle. The approach has been to combine on-farm epidemiological studies, with replicated experiments, in order to develop and demonstrate better systems of control applicable to UK organic farms. Preliminary data from the first years' epidemiological studies are presented in this paper.

A cooperative research project was started on balancing of soil organic matter in organic agriculture.  Existing balancing methods do often not produce plausible results, especially when applicated to organic farming. Therefore the project aim is to evaluate balancing methods and to characterize soil organic matter reproduction in organic farming on the basis of examination of field trials and practice farms in order to revise and adapt coefficients and algorythms in the balance methods. First tentative results from the project confirm the need for a revision and improvement of balancing methods since they did not reflect the actual organic matter dynamic in selected trials sufficiently. Significant differences in soil organic matter reproduction could be...

Development of a method for profiling of volatile organic compounds to monitor heat stress in hot water dipped apples
Provedor de dados: 21
Autores: Himmelboe, Martin.
Storage rot is a major contributor to losses of organic apples due to restrictions in spraying in orchards. Postharvest pre-treatments such as hot water dipping (HWD) have been proven successful to reduce storage rot. However, excessive heat during dipping easily induces heat stress and physiological disorders, which only show up after several weeks of cold storage. To develop further the HWD technology, a method for early detection of physiological disorders is desirable. As apples emit volatile organic compounds (VOCs) in response to stress and ripening, VOC profiling can be a useful tool for detecting the immediate heat stress and latent physiological disorders.  In this study, a selected ion-monitoring program was developed for analyzing VOCs from...

Development of a Methodology for Modelling Consumers’ Low Input Food Purchases
Provedor de dados: 21
Autores: Ness, Mitchell.
This paper explains the development of a methodology to model consumers’ purchases of low input and organic foods. The focus of the research design is the need to create value and satisfaction that exceeds consumers’ expectations and induces loyalty. The adopted analytical framework adopts a structural equation model (SEM) in the context of consumer loyalty research to explore the determinants of consumer loyalty in terms of constructs of perceived quality, perceived risk, sacrifice, perceived value and satisfaction. A General Model is proposed that permits the specification of nested models and hence, tests for the suitability of preferred models. The primary research instrument is a questionnaire applied to four products in five countries. The...

Pens in outdoor pig systems in general become permanent during the grazing period. The excretion behaviour of the pigs creates plant nutrient hotspots within  pens. In this study we developed a mobile organic piggery (MOP) without electric fencing that can be moved to a new grazing area each day. The aims were to distribute plant nutrients evenly, provide the pigs with continuous access to fresh herbage, and improve productivity and the working environment. Initially, 25 fattening piglets were installed in the MOP on a clover/grass ley. Nitrogen, P and K flows to and from the MOP were monitored during 87 days. The purchased feed included 80% of the energy norm for pigs in indoor systems and the pigs were automatically fed. The MOP was moved 65 times....

Development of a nature conservation standard for enhancing biodiversity and marketing in organic farming systems
Provedor de dados: 21
Autores: Stein-Bachinger, Karin; Gottwald, Frank; Dräger de Teran, Tanja; Rühs, Michael.
Abstract  Organic farms are proven to yield highly beneficial environmental services for nature. But an appreciation of these services by consumers is nearly non-existent. Furthermore the state does not offer sufficient financial support in this field. This has led to the situa-tion that many farms, due to economic constraints, cannot tap their nature conservation potential, even though the will to do so is very high. It is hoped that through the devel-opment of a nature conservation standard for organic farms connected with nature con-servation advisory services and rewarding farmers for facilitating environmental services by marketing organic+biodiversity products, farmers will experience a higher added value. At the same time consumers who purchase...

Development of a strategy for fire blight control in organic fruit growing
Provedor de dados: 21
Autores: Kunz, Stefan; Haug, Philipp.
Effective control strategies are needed in organic fruit growing to prevent blossom infections by the fire blight pathogen Erwinia amylovora. There are many potential control agents under discussion. 18 preparations have been tested for their efficiency against Erwinia amylovora.  Twelve of them were highly effective against E. amylovora in vitro.  Nevertheless only five of them led to a symptom reduction of  more than 50% on de-tached apple blossoms. These results and data on field performance from the literature indicate that Blos-som-Protect is the most effective preparation to prevent blossom infections by fire blight. Therefore further experiments have been performed to develop a strategy for the use of  Blossom-Protect in organic fruit grow-ing. The...

Development of an advisory system that supports good animal welfare in organic production in Norway
Provedor de dados: 21
Autores: Henriksen, Britt I. F.
Organic agriculture wishes to emphasise animal welfare, and aims to be at the forefront with regard to promoting the welfare of farm animals. It is therefore important to increase the expertise in the field of animal welfare in organic farming systems among veterinarians, advisers and farmers. An advisory service that includes on-farm assessment of animal welfare will contribute to securing a high level of animal welfare in organic production. To meet the need for information and expertise, an advisory and development project ”Good animal welfare in organic dairy farming”  started in May 2003 and will last until the end of 2005. The project’s main goal is to develop and establish a permanent advisory service aimed at securing a high level of animal health...

Development of an agroforestry system for chicken production
Provedor de dados: 21
Autores: Philipps, Lois; Engel, Cindy; Wolfe, Martin.
This report was presented at the UK Organic Research 2002 Conference. Because conventional production of chickens has gone further than any other animal production system towards complete control of the animal’s brief lives, development of effective silvo-poultry systems seems particularly necessary for these essentially woodland birds. The objective is to develop a production system that closely matches the physiological and behavioural needs of the animals being reared. For the example of chickens, this means trying to mimic a woodland/forest-clearing environment. By providing a wide range of trees, shrubs and herbs, it should be possible to provide shelter, nutrition and medicinal benefits for the birds. At the same time, the system needs to fulfil...

Development of an Environmental Management System for Organic Farms and its Introduction into Practice
Provedor de dados: 21
Autores: Huelsbergen, Kurt-Juergen; Kuestermann, Bjoern.
Increasing demands for documentation of farm activities as well as environment and quality assurance call for environment adapted management systems, also in organic farming.   The model software REPRO is a tool for farm management and consultation. It is distinguished by a systemic depiction of farming systems and can be used in agricultural practice.   The access to farm related data and site information is the basis for statements about matter cycles (C, N, P, K), humus budget, energy efficiency, erosion, soil structure and harmful soil compaction. Its application in rather differently structured farms under organic management discloses distinctly the relationships between the design of farming systems and their environmental effects. The possibility of...

In Switzerland there is an increasing consumer demand for residue-free, organic table  grapes. The organic cultivation of table grapes, however, is very delicate in humid climates  and experience to advice organic growers is still lacking. The goal of our project that has  started in 2004 is to develop and establish a cultivation system for organic table grapes  under Swiss climatic and economic conditions with a high yield security and fulfilling the  high quality demands of the market. Preliminary results: Interesting cultivars to produce  are e.g. Fanny, Lilla, Palatina. However they are disease susceptible and must be  produced under a rain roof. Better suited cultivars still need to be found. Consumer  acceptance for organic table grapes produced in...

Development of "Blossom-Protect" - a yeast preparation for the reduction of blossom infections by fire blight
Provedor de dados: 21
Autores: Kunz, Stefan.
In organic apple-growing control agents are necessary to prevent the blossoms being infected by  the fire blight pathogen Erwinia amylovora. Detached apple blossoms were used as an experimental  model to develop preparations based on yeast isolates for use in the control of fire blight. Several  yeast isolates reduced disease incidence in apple blossoms. The efficiency of yeast isolates  was increased by developing a suitable formulation. This yeast preparation exhibited high efficiency  in the control of fire blight in field-trials and will be marketed under the tradename "Blossom-  Protect".

Development of "Boni-Protect" - a yeast preparation for use in the control of postharvest diseases of apples
Provedor de dados: 21
Autores: Weiss, Armin; Mögel, Gudrun; Kunz, Stefan.
Postharvest pathogens cause major losses in apple production. Gloeosporium album (Pezicula alba) and Gloeosporium perennans (Pezicula malicorticis) are the main pathogens in organic fruit growing. There are several microorganisms with an antagonistic efficency against these fungi. Out of these organisms two yeast isolates have been chosen to develop the plant strengthener Boni-Protect. Boni-Protect reduced the symp-tom development of P. malicorticis, B. cinerea and P. expansum after artificial inoculation of apple wounds. In several field trials preharvest applications of Boni-Protect led to reduced disease development during stor-age.

Development of genetic models to breed for mixed cropping systems
Provedor de dados: 21
Autores: Haug, Benedikt; Messmer, Monika; Forst, Emma; Mary-Huard, Tristan; Enjalbert, Jérôme; Goldringer, Isabelle; Hohmann, Pierre.
Introduction  Mixed cropping, i.e. mixing different crops in the same field, provides agronomic advantages as increased productivity under low inputs conditions (e.g. for organic farming: Bedoussac et al. 2015) and higher yield stability (Raseduzzaman and Jensen 2017). In mixed cropping, choosing the right cultivars is critical for the performance of the mixture, as shown for pea-barley mixtures (Hauggaard-Nielsen and Jensen 2001) and maize-bean mixtures (Hoppe 2016). As performance in pure stand can strongly diverge from performance in mixture, estimating the ability of a cultivar to be mixed with another crop is therefore of utmost importance. For this purpose, concepts of General and Specific Combining Ability in hybrid breeding (Griffing 1956) have...

DEVELOPMENT OF MULTI-RESIDUE METHODS FOR PESTICIDE SCREENING IN ORGANIC FOOD SAMPLES
Provedor de dados: 21
Autores: Guignard, Cedric; Lenouvel, Audrey; Laursen, Kristian Holst; Husted, Søren.
There is an ever-increasing demand for foods of local origin or cultivated using organic practices. However, the sector is becoming dominated by corporate players that might not strictly fulfill all the requirements of organic farming, with or without fraud intentions. This places an increased burden on certification bodies and traceability systems on which the authenticity of the organic products depends. Thus, to ensure the authenticity of foods marketed and labelled as organic, there is a need for robust, accurate and validated control methods. The objective of the AuthenticFood project is to combine novel analytical techniques to improve the reliability of organic authentication. In this framework, the present work describes the development of...

Development of Near-Infrared Reflectance Spectroscopy to Estimate Oil Content in Safflower
Provedor de dados: 21
Autores: Rudolphi, S.; von Witzke-Ehbrecht, S.; Becker, H.C.
The oil of safflower (Carthamus tinctorius L.) is a valuable oil for human nutrition. It contains a high amount of unsaturated fatty acids, in particular linoleic acid (up to 90 %).  There is a great demand for ecologically produced oil in Germany, though oil crops are cultivated on 2 % of the ecological acreage.  In Germany, hardly any variety test exists, moreover there has been no breeding efforts so far, although genetic variation in safflower is large. The aim of this study was the development of a rapid and non-destructive method to determine oil content in safflower seed using NIRS (Near-Infrared Reflectance Spectroscopy).  A total of 203 seed samples were scanned with NIRS to estimate the oil content. Intact seeds as well as milled seeds were...

Organic farming is developing dynamically in the European Union. In Poland its growth is much slower and the area of organic farms still does not exceed 1%. Research shows that the main obstacles to the dynamic development of organic farming are short of properly educated consumers and lack of efficient distribution system of organic products in Poland and abroad. Regulations established before and after joining the European Union, in spite of some shortcomings, are not a barrier for development of organic farming in Poland.

Olive is the most extensively cultivated fruit crop in the world counting 9,2 million hectares of area harvested in 2009: 8,3 million are in the Mediterranean countries. This paper explain why the development of organic olive cultivation (5% of the total olive cultivation) can increase the sustainability of the Mediterranean. Regarding the ecological aspects, organic farming has benefits on landscape, biodiversity soil, water and air. Regarding economic sustainability organic olive oil production can be viable if the correct marketing channel is found. Regarding social sustainability, the olive oil consumption have a positive impact on health related to Mediterranean diet effects.

Autores: Gabertan, Herminigilda A.; Tepper, Lorna M.; Cueva, Mercedes L. Dela; Buctuanon, Eugenia M.
One and a half hectare organic seed production area was established in the Center. Organic seeds harvested were conserved for future use and a significant amount was distributed to farmer groups in partner areas and to other interested individuals in some important occasions. Existing practices used in organic crop production (including organic pesticides and nutrient supplements used) adopted by the Center were found to help in supplying nutrients to crop and in minimizing insect pests and disease occurrence. However, there is a need to do more detailed study on the effectiveness of these practices.    Evaluation of seed yield performance of different varieties of crops grown was done. Highest yielders were BPI-Cp3 (1.05 tons/ha) in cowpea; PSB Ps2 (1.54...

Development of phosphatase and dehydrogenase activities in soils of annual cropland and permanent grassland in an organic farm
Provedor de dados: 21
Autores: Ohm, M.; Paulsen, H.M.; Eichler-Löbermann, B.; Rahmann, G.
The essential nature of Phosphorus (P) in plant growth and the finite amount of P resources have result in the question: what kind of management in farming systems can lead to P sufficiency in organic farming? The release of acid and alkaline phosphatases of plant and microbes promote the plant availability of soil P. The presented results show a significant higher enzyme activity at permanent grassland (PG) than at arable land with annual crops at an organic farm in Northern Germany. Therefore livestock systems with PG for grazing ruminants seem to have high potential to improve on-farm P-cycles via feed and manure flows even to annual cropland. These systems can profit from the nutrient transfer from PG to arable land through the use of manures. Enhance...

Development of policies for organic agriculture
Provedor de dados: 21
Autores: Lampkin, Nic.
This report was presented at the UK Organic Research 2002 Conference. Since the late 1980s, policies to support organic farming have become widespread in Europe, in particular in the context of agri-environmental and rural development measures. Policies, originally focused on supporting conversion to and continued production, have been modified to recognise the need for the integration of marketing and information activities, in some cases delivered through national or regional action plans, examples of which are considered. The need for a strategic action plan at the European level has been identified and is under development. The outcome of this and the development of post Agenda 2000 organic farming policies to embrace an enlarged European Union is the...

We concluded that the preference for peers met at two weeks of age can be seen in proximity of the calves. However, calves can form stable relations at least until the age of 14 weeks. These relations reduce aggressive behaviour, activity and frequency of vocalization, and help calves to cope with new and potentially stressful situations.

Soil organic matter (SOM) and organic glues from biological processes are considered to be major contributors inaggregate formation. But there is limited knowledge on soil structural formation during initial soil development –the step when SOM content is low and soil properties are mostly controlled by the parent material. In our study we used a chronosequence approach in the re-cultivated open-cast mining area near Cologne, Germany to elucidate thedevelopment of soil structure and soil organic matter during initial soil formation in a loess material. We selectedsix plots with different ages of agricultural management after re-cultivation (0, 1, 3, 6, 12, and 24 years after firstseeding).

Development of strategies to improve quality and safety and reduce cost of production in organic and ‘low input‘ crop production systems
Provedor de dados: 21
Autores: Tamm, L.; Koepke, U.; Cohen, Y.; Leifert, C.
The overall aims of organic and low input crop production include the economically viable and environmentally sound production of high quality food and feed. Technological bottlenecks in such systems include insufficient and instable yields and in some instances unsatisfactory processing, sensory and/or nutritional quality of the final product. Recently, concerns have also been raised that the intensive use of manures may lead to increased risk for contamination of food by enteropathogenic micro-organisms. Crop production in low input systems is based on key pillars, i.e. (i) a fertile soil which provides sufficient capacity to allow for plant growth while preventing soil-borne diseases, (ii) high quality, disease-free seeds and plant material, (iii) a...

Development of the FBC model to estimate the nitrogen available from fertility -building crops in organic rotations
Provedor de dados: 21
Autores: Cuttle, S P.
The FBC (Fertility Building Crops) model has been developed as a planning tool to provide organic farmers with information about how much nitrogen will be available in the soil at different stages following the ley phase of the rotation. It predicts the likely crop yields under this level of nitrogen supply and provides an estimate of how much nitrogen will be lost by leaching and denitrification so that if necessary the grower can examine the effects of modifying the rotation to improve the efficiency of nitrogen use and minimise losses. The model is easy to use and requires only the sort of information that is readily available to commercial growers. Although it appears to provide realistic simulations of a range of crop rotations and conditions, it has...

It will question the building up of the organic concept in terms of national policies, farming practices and market forces in the country.   That topic has its scientific relevance at least in three crucial dimensions. Firstly, because the legacy of the socialist system significantly affected the structure of the agricultural sector as well as the entrepreneurial behavior of the rural population under conditions of transition.

Autores: Paulsen, Hans Marten; Schädlich, Olaf; Oppermann, Rainer.
Local oil mills, processing organic oilseeds solely, suffer competitive disad¬vantages by lower workloads due to low organic yields. Organic rapeseed oil as sub¬stitute for diesel fuel is not economically justifiable due to its high production costs and opportu-nity costs in the food market. Only organic sunflower oil or oil of false flax (Camelina sativa) grown in mixed cropping systems have produc¬tion costs comparable to con-ventional rapeseed oil. An ecobalance showed that false flax oil from mixed cropping systems as substitute for diesel has clear ecological advantages compared to oil from single cropped oilseeds. But the use of false flax as fuel in engines is still not proofed in science and technology.

Diagnostic of post-weaning diarrhoea on the farm level
Provedor de dados: 21
Autores: Sundrum, Albert; Goebel, Amke; Werner, Christina.
Introduction  Post-weaning diarrhoea (PWD) is a multi-factorial disease. Clinical symptoms are often linked to a combination of different factors such as specific pathogens, low feed intake after weaning, low hygiene, low age at weaning, low piglet live weight at weaning, and a high number of piglets per pen (Madec et al., 1998). Although organically reared piglets are, in general, six weeks of age at weaning, and are kept with a high space allowance, post-weaning diarrhoea is a severe problem in organic pig production (Bonde &amp; Sörensen, 2006; Sundrum et al., 2010). Due to restrictions in the use of antibiotics in organic livestock production, there is a need to focus primarily on the implementation of preventive measures. When health problems are...

Die deutschen Märkte für Ökologische Nahrungsmittel im Jahr 2007 - Perspektiven und Probleme
Provedor de dados: 21
Autores: Rahmann, Gerold; Oppermann, Rainer.
Der deutsche Biomarkt boomt. Ist dieses nur eine kurzzeitige Erscheinung oder nachhaltig?    Der Biomarkt in Deutschland ist einer der dynamischsten Biomärkte in der Welt. Die Aussichten für die nahe Zukunft sind gut. Andererseits gehören immer noch erst rund 10% der Verbraucher zur Gruppe der Intensivkäufer. Dies sind Menschen, für die der Einkauf von Bio-Lebensmitteln zum wichtigen Kennzeichen ihres persönlichen Lebensstils geworden ist.    Abstract:   Die ökologische Lebensmittelwirtschaft hat die Aufgabe noch nicht gelöst, sich als Alternative für breite Konsumentengruppen zu profilieren. Um diese Aufgabe anzugehen, muss der Qualitätskommunikation und der Vertrauensbildung in Zukunft größere Aufmerksamkeit widmen. Dazu gehört auch die offensive Arbeit...

Die Eignung der Leitfähigkeitsmessung zur Eutergesundheitsüberwachung bei Milchschafen
Provedor de dados: 21
Autores: Barth, Kerstin; Burow, Elke; Knappstein, Karin; Ubben, Ernst-Heinrich.
Sheep milk production is not very common in Germany. Only 10,000 sheep are used for milking. However, a considerable number of farmers work according to the stan-dards of organic farming. Only farm dairies process the milk and sell the products directly to the consumer. Thus, the quality of the raw milk has to be high although the EU regulations for sheep milk are not as strict as for cow’s milk. Animal recording is not a standard in dairy sheep production and farmers lack the information which might be gained by this monthly monitoring of each animal. Animal side tests are necessary and the aim of our study was to investigate the usability of conductivity measurement as an indicator of sub clinical mastitis in ewes. Data were collected from 164 ewes in...

Die Entwicklung des Ökologischen Gartenbaus in der Obstbausiedlung Eden
Provedor de dados: 21
Autores: Hoffmann, Heide; Marx, Grit.
Zusammenfassend ist festzustellen, dass die Anwendung des Ökologischen Gartenbaus im alternativen Siedlungskonzept Eden immer von äußeren gesellschaftlichen Bedingungen geprägt wurde und siedlungsintern modifiziert wurde. Auch wenn die Gründer Edens eine Nische besetzen sollten, war der Einfluss der äußeren Welt auf ihre Handlungsweisen im Verlaufe der Jahre zunehmend  dominant. Weiterführende Untersuchungen bei anderen alternativen Konzepten ermöglichen es, verallgemeinernde Schlussfolgerungen zu ziehen.

Autores: Bussemas, Ralf; Kocerka, Claudia; Weißmann, Friedrich.
A comparison of 54 litters of individual versus 54 litters of group housed organic lactating sows (grouped at three) beginning with day 14 after birth demonstrated that – despite significant behavioural adaptation and agonistic behaviour of the group housed lactating sows – the piglets’ body weight development, diseases and loss rates were similar between the two housing systems. In consequence there were no differences in productivity between the litters of single and group housed lactating sows.

Die gute alte Fruchtfolge als Bekämpfungsmethode gegen den  Maiswurzelbohrer (Diabrotica virgifera virgifera LeConte)
Provedor de dados: 21
Autores: Bertossa, M.; Schaub, L.; Colombi, L.
Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae), the western corn rootworm  (WCR), is an immigrant from North America and one of the top ten global agricultural  pest species. Within the last 15 years, WCR invaded Europe at 3 focal points, and has  been steadily extending its domain soon threatening commercial maize production.  After the first detection in Switzerland in 2000 near Lugano, careful observations by  pheromone trap monitoring of this quarantine organism have been realized.  Experiences with WCR whose populations dynamics are incompletely understood,  have also been studied by installing a continuous maize field comparing population  dynamics with rotated maize fields in the immediate surroundings. Our experiences  with WCR...

Die Hierarchische Wirtschaftlichkeitsanalyse – eine Methode zur ökonomisch umfassenden Bewertung des Ökologischen Landbaus auf regionaler Ebene
Provedor de dados: 21
Autores: Kratochvil, R.; Kaliski, O.
Bisherige Analysen möglicher ökonomischer Konsequenzen einer großflächigen Bewirtschaftung nach den Richtlinien des Ökologischen Landbaus setzten zur Beantwortung ihrer Fragestellungen semi-quantitative Methoden, Lineare Programmierungsmodelle oder allgemeine Gleichgewichtsmodelle ein (vgl. KRATOCHVIL et al. 2002). Methoden, die die ökonomischen Effekte auf verschiedenen Ebenen (betrieblich – regional – volkswirtschaftlich) mittels aufeinander aufbauender Methodenbausteine bewerten, kamen im Rahmen dieser Fragestellung bis dato nicht zur Anwendung. Ziel des vorliegenden Beitrages ist es daher, die Eignung einer derartigen Methode - der Hierarchischen Wirtschaftlichkeitsanalyse – für agrarwissenschaftliche Fragestellungen im Allgemeinen sowie für eine...

Die Hohenheimer Box:   Entwicklung einer Methode zur Vor-Ort-Massenzucht der Erzwespe Lariophagus distinguendus gegen Vorratsschädlinge
Provedor de dados: 21
Autores: Niedermayer, Steffi; Steidle, Johannes L.M.
Biological pest control is an important tool in stored products protection. To improve the biological control of the granary weevil Sitophilus granarius L. (Coleoptera: Curculionidae), a rearing box for the parasitic wasp Lariophagus distinguendus (Förster) (Hymenoptera: Pteromalidae) has been developed. The box contains breeding substrate as well as populations of hosts and parasitoids and is placed directly in the storage site. A special outlet prevents hosts from leaving the box while freshly emerged parasitoids are released continuously over several months. A repeated shipment of wasps has thereby become obsolete.

Die Domäne Frankenhausen – Kulturlandschaft als Aufgabe: Die Hessische Staatsdomäne Frankenhausen bei Kassel wurde ab Juli 1998 auf Ökologischen Landbau umgestellt und dient als Versuchs- und Lehrbetrieb der Universität Kassel. Zuvor hatte der Betrieb in den letzten drei Jahrzehnten die typische Intensivierung der konventionellen Landwirtschaft durchlaufen: 1971 wurde die Erzeugung von Vorzugsmilch aufgegeben, zwei Jahre später das letzte Vieh abgeschafft und seither reiner Ackerbau (Schwerpunkt Saatgetreide und Zuckerrüben) betrieben. Die Landschaft ist ein Spiegelbild der intensiven Nutzung: Ausgeräumte und drainierte Acker-schläge, tief in den Löß eingeschnittene und teilweise kanalisierte Fließgewässer, Dominanz von Eutrophierungszeigern und...

Die Kosten der Koexistenz von gentechnisch veränderten und  biologischen Kulturen: Fallbeispiele aus Frankreich und der  Grenzregion
Provedor de dados: 21
Autores: Oehen, Bernadette; Stolze, Dr. Mathias.
Coexistence issues have been to a large extent focused on technical measures to  avoid the adventitious presence of gm material in non-gm crops. Information about  costs involved in growing GM, conventional and/or organic crops in the same agricultural  system are not available. In this case study, we investigated the coexistence  costs of gm and non-gm grain maize for the gm maize and the non-gm maize producer.  From our simulation results we can conclude that the benefits of gm maize production  can only cover the potential coexistence and management costs in cases of i)  small discard zone distances and ii) in cases with high gm maize adoption rates of  90%.

Die landwirtschaftliche Baukultur nachhaltiger gestalten und die kommunikative Wirkung der Bausubstanz erkennen
Provedor de dados: 21
Autores: Dauermann, Angelika; Enneking, Ulrich.
Gebäude sind nicht nur als Funktionseinheiten zu betrachten, sondern auch als Kommunikationsmedium. Die bauliche Gestaltung eines jeweiligen Gebäudes lässt viele Rückschlüsse bezüglich der Einstellungen und Werthaltungen der Bauherrin oder des Bauherrn zu. Und so geben auch Schweineställe und Feldscheunen Informationen über das Wertegefüge des jeweiligen landwirtschaftlichen Unternehmens preis. Die finanziellen Spielräume der Agrarbetriebe sind oftmals nicht groß bei baulichen Investitionen. Unreflektiert sollte die agrarische Baukultur deswegen allerdings nicht bleiben. Die folgenden Ausführungen zeigen auf, dass ein landwirtschaftlicher Betrieb durch eine reflektierte Baukultur einen Zugewinn an Authentizität in der öffentlichen Wahrnehmung erfahren kann.

Die Landwirtschaftliche Individualität in der biologisch-dynamischen Landwirtschaft und ihre Bezüge zur Wissenschaft
Provedor de dados: 21
Autores: Morau, Alain; Fritz, Jürgen.
Die ‘Landwirtschaftliche Individualität’ ist der grundlegende Begriff der biologisch-dynamischen Landwirtschaft. Er ist allerdings mit der wissenschaftlichen Diskussion wenig verbunden. Unser Ziel ist es, einige Aspekte davon und seine aktuelle Bedeutung zu erklären. Die 'landwirtschaftliche Individualität’ beschreibt die Gesamtheit von allen Tieren und Pflanzen samt dem Biotop in einem Betrieb. Dabei wird diese Gesamtheit als ein Organismus höherer Art betrachtet. Als Rudolf Steiner diesen Begriff 1924 einführt, werden zur gleichen Zeit ähnliche Ansichten in der Naturwissenschaft entwickelt, insbesondere in der Ökologie mit dem Begriff des Holozöns. Diese ganzheitlichen Ansichten geraten später allerdings in Vergessenheit. Heutzutage gibt der aktuelle...

Aus diesen Ergebnissen läßt sich schließen, daß die Marktausweitung der vergangenen Jahre weniger auf Impulsen von der Nachfrageseite beruhte, sondern hauptsächlich bedingt war durch Aktivitäten der Anbieter, vor allem durch (1) sinkende Preise (als Folge von Angebotsausweitungen, die u.a. auf Fördermaßnahmen zurückzuführen waren), (2) die Ausweitung der Distribution und (3) durch die Ausweitung der Sortimente sowie die Verbesserung der  Produktqualitäten.  Die zukünftige Entwicklung des Bio-Marktes wird in erster Linie durch die Intensität und Qualität dieser Marketing-Aktivitäten bestimmt sein. Die Auswertungen sind zum Berichtszeitpunkt (31.5.2000) noch nicht abgeschlossen.

Die Rolle der Erzeugergemeinschaften auf dem deutschen Markt für ökologisch produzierte Produkte - Eine empirische Untersuchung
Provedor de dados: 21
Autores: Madsen, Gudula.
There are inadequate reliable data about the organic food market in Germany. Producer cooperatives (Erzeugergemeinschaften-EZG) play an important role in distributive trade. The research objective is to identify the amount of products brought to the market by the EZGs as well as their position in the market. The analysis is empirical. The interviews are conducted by telephone. Particularly EZGs deal with raw products and mainly with the products of their members. Small purchases are only made to ensure continuous supply to customers. The relevance of own processing is small. EZGs made a contribution to the development of the market of organic food by providing a good supply for their customers. They combine the offers of their members into a bundle, they...

Even though sunflower is primarily considered an oilseed crop, sunflower meal or cake is interesting for animal food, especially for organic farming, where the supply of protein is complicated. The quality of the oil cake is determined by its protein content. A breeding goal for the use of sunflower meal as a protein source is thus to increase the protein content of sunflower seeds without decreasing the oil content.

Die Umstellung auf ökologischen Apfelanbau unter Berücksichtigung von Unsicherheit
Provedor de dados: 21
Autores: Zander, Katrin; Garming, Hildegard.
Eine Umstellung von konventionellem auf ökologischen Apfelanbau ist ein Systemwechsel und unabhängig vom Motiv der Umstellung für den Entscheidungsträger mit Kosten und mit Risiken verbunden. Die Ergebnisse der Untersuchung zeigen, dass die Rentabilität der ökologischen Apfelerzeugung entscheidend von der Intensität der ökologischen Bewirtschaftung abhängt. Unter den getroffenen Annahmen auf der Basis von Literaturangaben und Expertenschätzungen kann im relativ intensiven ökologischen Apfelanbau auch bei Berücksichtigung von Risiko ein positives Betriebsergebnis erwartet werden, so dass eine Umstellung rentabel ist. Dennoch ist festzuhalten, dass sinkende Preise und unterdurchschnittliche Erträge die Wirtschaftlichkeit der Umstellungsentscheidung in Frage...

Die Untersuchung der Überlebensfähigkeit von infektionsfähigen Endoparasitenlarven in Silagen unterschiedlicher Qualität
Provedor de dados: 21
Autores: Podstatzky, Leopold; Thurnhofer, R.
The aim of this study was to analyze the influence of silage quality and duration of ensiling to the recovery of  infectious larvae of endoparasites. 48 silage bags of  different quality were prepaired (gras, gras and earth, gras and silage additive, gras and earth and silage additive). Third larvae of a parasite larvae mixture were added.  Larvae were recovered by the methode of Baermann-Wetzel. Significant differences were seen between groups in the larval recovery with more recovery in groups with  additional earth. Differences in pH were ambivalent, but samples without added earth were at least numerically better.

Autores: Keppler, C.; Lange, K.; Fölsch, D.W.
Artgemäße Legehennenhaltungssysteme zeichnen sich durch verschiedene Funktionbereiche, wie erhöhte Standorte und Sitzstangen, ausreichend Scharraum, Staubbademöglichkeit, Nester, Außenklimabereich und Auslauf aus. Die Ställe sind mit Tageslicht ausgeleuchtet und die Tiere werden nicht schnabelkupiert.     Konventionell in Dunkelställen, ohne erhöhte Sitzstangen aufgezogene Tiere zeigen Verhaltensänderungen und häufig Federpicken, das bis hin zum Kannibalismus führen kann. Eine Verringerung der Schäden wird durch eine Lichtreduktion des Kunstlichtes bis auf 10- 15 LUX erreicht. Junghennen aus konventioneller Aufzucht sind aus diesen Gründen nicht für die Einstallung in artgemäße Legehennenhaltungssysteme mit Tageslicht geeignet. Ziel dieser Untersuchung...

Autores: Wittwer, Raphaël; Jossi, Werner; van der Heijden, Marcel.
Several studies indicate that cover crops can be used to enhance agricultural sustainability as they provide numerous ecological services in agro-ecosystems. They protect soil against erosion and nutrient losses and compete weeds. Moreover, legume species fix nitrogen (N) from the atmosphere and contribute to next crop nutrition. Hence, cover crops complement the ecological aims of organic agriculture. We investigated the impact of cover crops in different cropping systems (organic and conventional) and soil tillage intensities (plough, reduced and no-tillage) in various field experiments. Moreover, results from an experimental network, which has investigated the behavior of more than 11 cover crops, is included. Results show that  the effects of cover...

In a holistic approach customers were asked in qualitative interviews about their perception of organic farms which run their own shops. Besides the organic quality they like the competent service, the traditional look and details. They regard the farms shops as pleasant. Many customers visit the farm and animals. Other consumers living near the farm like a wide range of products contact to their neighbourhood and exchange information. The seasonal fluctuations in supply are accepted. Most customers, though different in age and motivation, are aware of ecological and health topics. Customers praise the good taste, the real freshness and good quality.

The concept of „unpackaged shopping“ aims at reducing waste along the entire value chain. Our project focusses on analysing the value chain of unpackaged food with  regard to potentials, barriers and opportunities to expand the concept. The first results revealed that there are several challenges for “unpackaged shopping” to be observed,  which can be grouped under six perspectives: supply, marketing, “inside”, “outside”, environment, and branch. For instance, the producers and suppliers are hesitant to  change packaging processes due to a lack of demand, wholesalers are faced with potential additional cost for deposit systems, stores are having difficulties finding  appropriate products and customers are struggling with the additional efforts of...

Feeding hazelnut leaves (Corylus avellana) to first year grazing goats may reduce the egg output of gastrointestinal worms. Previous trials with complete hazelnut bushes support this assumption. Under controlled conditions, the feeding of hazelnut leaves of four weeks, showed no significant differences concerning body weight and fecal egg count between control, low dose and high dose groups, respectively. Anyhow, the great acceptance of hazelnut leaves shows, that browsing does increases animal welfare of goats.

At the Experimental Farm of the Thünen Institute of Organic Farming the effect of sulphur fertilisation in form of MgSO4 and CaSO4 of a red clover-grass mixture was tested in the years 2013 - 2015. At the beginning of the vegetation period clover-grass plots were fertilised in the first and second year of usage with 30 and 60 kg S ha-1 and were compared to unfertilised plots. The fertilisation resulted in significantly higher fresh weight and - with one exception of the second year usage in 2013 higher dry matter yields. The forage quality was significantly increased by sulphur fertilisation. Due to higher sulphur contents in the fertilised plots the N/S-ratios showed values below the threshold of 15 for an adequate sulphur supply. The N-withdrawals...

Type and rate of fertilizer influence the level of organic carbon and total nitrogen in the  soil markedly, but the effect on different pools is open to question. Soil samples were  taken from a sandy Cambisol at Darmstadt, Germany, after 27 years of different  fertilization treatments. The six treatments were: straw incorporation plus application  of mineral fertilizer (MSI) and application of farmyard manure (FYM) each at high (140  – 150 kg N ha-1 year-1), medium (100 kg N ha-1 year-1) and low (50 – 60 kg N ha-1  year-1) rates. After 266 days of incubation (10°C, 50% water-filled pore space)  mineralization of C (1130 – 1820 kg ha-1) and N (90 – 125 kg ha-1) depended on the  rate and not on the type of fertilizer.

In warm-blooded animals such as humans and pigs the intestinal microbial composition is dependent on the type of ingested diet. It is known that it also influences the immune system and prevent colonization of pathogenic bacteria. The question is if the gut microbiota has the same impact in lower vertebrates such as fish?   To examine this rainbow trout fry were fed two different diets of either a marine or vegetable origin. At a size of about four gram a subset of the fish was bath challenged by Yersinia ruckeri serotype O1 and intestines were then sampled 5 days post challenge from challenged fish (n = 40) and non-challenged control fish (n = 40). Subsequent metagenomic examination based on the 16S rDNA gene was then performed using the Illumina HiSeq...

The potential role of nitrite as an antimicrobial substance in the stomach may be of some importance in the ecology of the gastrointestinal tract and in host physiology. It has been shown that nitrite, under the acidic conditions of the stomach, may kill gut pathogens like Salmonella enteritidis, Escherichia coli, Salmonella typhimurium, and Yersinia enterocolitica, whereas acid alone has only a bacteriostatic effect. An in vivo study was conducted in order to assess the effects of dietary nitrate on microbiota and on the health of the gut (particularly in the stomach and small intestine). 96 weaning pigs were fed a diet containing high nitrate levels (15 mg and 150 mg) and then challenged with Salmonella enterica serovar typhimurium.

Differences between spring wheat cultivars for emergence and early development after seed infection with Fusarium culmorum
Provedor de dados: 21
Autores: Timmermans, B.G.H; Osman, A.M.
Infection of wheat seeds with Fusarium spp. causes seedling blight. As a result of this disease, fields sown with infected seeds show a reduced plant density. This is especially a problem in organic agriculture, for which currently no practical seed disinfection methods are available. In the present project we investigated whether spring wheat cultivars differ in sensitivity to seedling blight, whether the possible differences could be linked to cultivar differences in early growth rates, and what size the delay in canopy closure resulting from the plant reductions was. Six spring wheat cultivars (Melon, Lavett, SW Kungsjet, Epos, Pasteur, Thasos), containing three infection levels (averages 5, 15 and 27%) of Fusarium culmorum were obtained and were sown...

Autores: Timmermans, Dr. B.G.H.; Osman, Ir. A.M.
Fusarium spp. present on spring wheat seeds can infect seedlings and cause reduced plant densities and higher wheat infestations. In the current project, variation between commercially available spring wheat cultivars in their tolerance to Fusarium seedling blight was investigated in a pot and a field trail. Additionally, initial growth rates of cultivars were measured to investigate possible relations with tolerance. Preliminary analysis shows presence of  tolerance differences between the spring wheat cultivars in the pot and field experiment. This difference was relatively robust (experiment x cultivar interaction was not significant). Preliminary analysis also showed a relation between tolerance and initial growth rates of cultivars in the field...

DIFFERENCES IN FEEDING PRACTICES ON ORGANIC AND CONVENTIONAL DAIRY FARMS – DATA FROM A FARM NETWORK
Provedor de dados: 21
Autores: Warnecke, Sylvia; Schulz, Franziska; Paulsen, Hans Marten; Rahmann, Gerold.
Organic and conventional feeding practices of dairy cattle differ due to specific regulations that are in place for organic farming. E.g., dairy cows must have access to pasture, and soybean extract, a very common concentrate in conventional dairy feeding, may not be fed. The joint project “Climate Effects and Sustainability of Agricultural Systems – Analyses in a Network of Pilot Farms” determined feeding practices and feed qualities on a total of 44 dairy farms (22 organic and conventional, each) in four German regions for 2008, 2009 and 2010. The average diets of the dairy cows differed considerably between organic and conventional dairy farms. Organic farms with a high percentage of hay in the diet were found in East and South Germany.

Breeding goals of Holstein dairy cattle in New Zealand (NZL) focus on traits reflecting adaptation to pasture-based systems. Due to high prices for concentrates, and advantages for cattle health and welfare, low input grazing systems become important in regions of North-West Germany. The present study addresses the hypothesis that progeny of NZL-Holstein sires are superior in 30 German grassland farms compared to offspring of Holstein sires being progeny tested in German indoor systems. A research design was implemented to create three different genetic groups (F1 generation) within herds on the basis of a German Holstein cow (GHC) population: Group 1=GHC x NZL sires, group 2=GHC x GH sires, group 3=GHC x GH_pasture sires.

Different standing crops for organic layers
Provedor de dados: 21
Autores: Horsted, K.; Hermansen, J.E.
In typical organic egg production systems nearly all the feed is imported and fed inside the henhouse. Moreover, most of the hens stay inside the house or predominantly use the area just in front of the hen house. In consequence many systems are exposed to an unacceptable accumulation of nutrients in the most utilized areas in the hen yard. It is the hypothesis that this drawback can be affected if the feeds for a higher degree are based on foraging within the hen yard.    The purpose of this study was to estimate the effect of including standing crops in the hen yard on feed intake, production parameters, recirculation of nutrients in the system and the welfare of the poultry.   Two experiments with different standing crops for laying hens were conducted...

Apple scab remains one of the main disease, responsible for significant economic losses. Selection of tolerant varieties is a promising way to follow, but is not yet giving satisfying results. Thus, different strategies have to be developed and enhanced: the screening of alternative control inputs, with lower copper dosage or without any copper is essential for short term answers to growers. This research give interesting results and potential new ingredients, however not as efficient as copper sulphate. Simultaneously, biology of the fungus permits a more preventive strategy, by destroying leaves at fall season, and thus highly decreasing the scab infection potential.

Fertile soils are highly important for arable farming. To maintain soil fertility, crop rotation including legumes is applied, particularly in stockless farms. Yet, many commercial farms report yield reductions for legumes. The aim of the present study was to evaluate whether the causes for the observed soil fatigue can be narrowed down by a bioassay (modified differential diagnosis according to Bouhot) and whether this bioassay could be a useful tool to predict the suitability of a field to grow legumes.

Digested slurry injected produces in this case comparable yields with mineral fertiliser. Because the primary growth is the largest and of the best quality it should be used for feed as the first option. The re-growths could then be used as a co-substrate in biogas reactors. Digested slurry is a good fertiliser for leys when injected. Injection of non-digested slurry reduces the ammonia emissions and leaching of soluble phosphorus but the significance of the low performance of nitrogen leaves open its fate.

Digital images for assessing soil cover of crop plants
Provedor de dados: 21
Autores: Rasmussen, Jesper; Nørremark, Michael.
The main drawback by using crop soil cover in weed harrowing research is that it is assessed by visual scores, which are biased and context dependent. This problem may be solved by using digital image analysis. In this paper a new image capture standard and digital image analysis procedure was used to illustrate three key issues in relation to weed harrowing; selectivity, resistance and recovery. All issues require reliable assessments of crop soil cover. Crop soil cover was deduced from assessments of leaf cover, which is defined as the proportion of pixels in digital images determined to be green.     Objective assessments of leaf cover and crop soil cover showed that the selectivity of weed harrowing in winter wheat and spring barley was unaffected by...

Dinitrogen fixation and residue nitrogen of different managed legumes and nitrogen uptake of subsequent winter wheat [N2-Fixierung und  residualer Stickstoff verschiedener Futterleguminosen sowie N-Aufnahme der Folgefrucht Winterweizen.]
Provedor de dados: 21
Autores: Loges, Ralf; Kaske, A.; Taube, F.
Fixed nitrogen accumulated by legumes is the main nitrogen source for organic farming systems. Knowledge about the amount of fixed nitrogen, its pathways into forage yield, crop residues, soil-N and yield formation of the following crop is needed for designing crop rotations.    Two field experiments were conducted in Northern Germany with differently managed (cut, mulched) legumes (red clover, alfalfa, white clover) in pure stands and various mixtures with two companion grasses (Lolium multiflorum, Lolium perenne) have been grown to determine N2-fixation, residue nitrogen and N-uptake of subsequent crops.     Cropped grass/legume reached higher N2-fixation than mulched. While green manure grass/legume left up to 280 kg ha-1 of N in mulch, stubble and...

Diplodia seriata, cause of black fruit rot in organically grown apples in Holland, Belgium and Northern Germany
Provedor de dados: 21
Autores: Trapman, Marc; Maxin, Peter; Weber, Roland W. S.
A fruit rot resembling Gloeosporium infections but appearing on fruits prior to harvest was  noticed in organic apple orchards in Holland, Belgium and Northern Germany in 2007.  Infections were most commonly observed on ‘Elstar’, but other cultivars were also  affected. Fruit colonisation progressed in two steps, whereby a latent stage of sunken  black lesions in immature fruits gave rise to a rapidly spreading firm brown rot upon fruit  ripening. Isolation experiments from both stages consistently yielded a single species of  fungus identified as Diplodia seriata, formerly known under the teleomorph name  Botryosphaeria obtusa. Lesions of D. seriata were also seen on leaves as necrotic light  brown spots surrounded by a purple halo, and occasionally on...

There is a lack of research into why consumers value process characteristics. In this study, we test the hypothesis that the impact of process characteristics such as organic and free-range on consumers’ choices of food products is at least partly mediated through expected eating quality or taste expectations. In other words, the process characteristics partly function as cues to (eating) quality. Using a traditional metric conjoint approach based on an additive model, four product characteristics (production method, price, size and information about farmer and rearing conditions) were varied in a fractional factorial conjoint design, creating nine profiles of whole chickens. 384 respondents rated the nine different chickens in terms of taste expectations...

Direct marketing of beef in organic suckler cattle farms: economic results and impact on breeding system management
Provedor de dados: 21
Autores: Veysset, Patrick; Ingrand, Stéphane; Limon, Mathilde.
In response to the bovine crises of 1996 and 2000, and also to the poorly structured organic beef market chain, direct marketing of beef to consumers by the farmer has developed. We studied the impact of this marketing system on economic performance and farming practices. The results show that direct marketing can generate added value, despite the extra costs. Farmers have made the necessary changes to their practices, and have adapted their herd management. Through strengthening the link between the farm and the outside world, direct marketing offers an alternative to the expansion of farms, making it possible to support a greater workforce with the same structure.

Direct payments coupled to labour force – socio-economic consequences to organic farming –
Provedor de dados: 21
Autores: Stolze, Matthias.
Discussion   Labour input on organic farms in Switzerland and Germany is on average 20% higher than on comparable conventional farms (Offermann and Nieberg 2000). Therefore, it is not surprising, that policy-makers expect positive impacts both on organic farming development and on rural employment by modifying the current direct payment approach. However, Dabbert et al. (2002) expect only minor effects to agricultural employment due to the small size of the sub-sector.   The supporters of modified payment schemes argue, that coupling direct payments to labour force might lead to a fairer allocation of subsidies. ‘Fairer allocation’ in this context means reallocation of payments from large farms with low labour input per hectare to small family farms where...

Direct Seeding of Faba Beans in Organic Agriculture
Provedor de dados: 21
Autores: Köpke, Prof. Ulrich; Schulte, Harald.
Field experiments carried out at two experimental sites over two years showed that temporary direct seeding (DS) of faba beans (FAB) is possible in Organic Agriculture (OA) when weed pressure of perennials is low. Weed density of DS treatments was significantly lower when compared with mouldboard plough (MP, control) although no clear effects on annual weeds were given by the precrop oats neither by the amount of crop residues (0, 4, 6 t ha-1) nor the sowing density of autumnal sown oats (0, 600, 1200, 1800 seeds m- ) simulating hail-shattered grains. No significant differences in grain yield but lower costs of labour and fuel were determined for DS compared with MP. Estimated DS gross margins exceeded MP gross margins when DS yield losses   remained lower...

Herkömmliche Maisanbausysteme führen häufig zu vielfachen Anbauproblemen und umweltgefährdungen: Nitratauswaschung, Bodenerosion und ein hoher Aufwand für die Unkrautregulierung. Aufgrund dieser Probleme ist der Maisanbau im Ökologischen Landbau nicht stark verbreitet. Zugleich besteht dort ein großer Bedarf an einem energiereichen Grundfutter, so dass der Mais gut in den Ökologischen Landbau passen würde. Viele Strategien zur Lösung dieser Probleme führen oft zu neuen Problemen, sind häufig wirkungslos und meistens mit zusätzlichen Kosten verbunden. Das Zweikulturnutungssystem für Mais vermeidet diese Probleme. Als Erstkultur wird Ende September eine Wintererbse ausgesät.

Direct and indirect methods for determining the technological flour quality of modern wheat varieties with high gluten quality have been assessed. Direct methods like the commonly used Rapid-Mix-Test (RMT) and an optimized baking test were compared to the indirect parameters gluten and crude protein. The results for the optimized baking test in 2007 showed more than 30 % higher loaf volume (713 ml/100 g flour) compared with the RMT (544 ml/100 g flour). In this selection of varieties, the determination of wet gluten between two laboratories showed no consistency in the results. In addition to that, very good flour quality (&gt;660 ml/100 g flour) started on a relatively low crude protein level of flours &gt; 9,0 %, but low correlations were obtained for...

Disease control by sulphur induced resistance
Provedor de dados: 21
Autores: Haneklaus, S; Bloem, E; Schnug, E.
As early as the 19th century, Justus von Liebig (1803 – 1873) identified the lack of vitality of soils and non-existent vigour of plants as relevant causes of increased infections of crops by fungal diseases. Organic farming requires alternative strategies for combating pests and diseases. Soil-applied sulphate fertilisation proved to significantly reduce infection rate and severity of crops by fungal diseases. The potential efficacy of socalled Sulphur Induced Resistance (SIR) expressed as a reduction of the disease index ranged from 5–50% and 17–35% in greenhouse and field experiments, respectively. Metabolic pathways involved in SIR imply, for instance, the synthesis of phytoalexins, glutathione, glucosinolates and the release of sulphur-containing...

The effect of 3 new natural fungicides to control Monilia (Monilia laxa) of sweet cherry as well as the  effects of plastic cover during flowering period were tested in different trials on 4 organic farms in  Switzerland during three years. Under low to medium disease pressure Serenade (Bacillus subtilis),  Trilogy (Azadirachtin-free Neemoil) and lime sulphur reduced Monilia incidence by 30 to 60 %  relative to control. With high disease pressure, however, non of these products had a relevant  controlling effect.

Quality compost can have a positive effect on soil fertility and plant growth and health.  This positive effect is not only observable in the laboratory, but also by growers.  Phytopathological problems could be solved with the use of compost.  Durable success can only be obtained if a quality management is resolutely followed.  Further research is needed to optimize the quality management of compost production and  utilization. For example, very little is known about the long-term effect of the different composts on soil fertility and disease receptivity.

Disease management in organic apple orchards is more than applying the right product at the correct time
Provedor de dados: 21
Autores: Trapman, Marc; Jansonius, Pieter Jans.
The relative importance of diseases on apple is varying with cultivar, management, time,  and climate. Many aspects of the cropping system influence the development of diseases.  The choice of the variety determines the disease management during the lifetime of the  orchard. Cultural practices improve the growth and nutrial status of the tree, and therewith  influence the susceptibility of the plant and fruits to diseases directly. Prolonged growth  can also have an indirect effect by causing a microclimate and growing pattern that  favours infection of tree, leafs and fruits by various diseases. Sanitation measures are  common practise for most organic fruit growers and help to make other measures more  effective by reducing infection inoculums. Despite...

Despite quite intensive testing of varieties, predictions of future performance of varieties, when grown on specific locations, are known to be nearly impossible; this especially within organic growing systems, where no pesticides and fertilizers can help stabilize yield. Therefore, using mixtures of appropriate varieties might be a way to obtain more stable and acceptable yields. Variety mixtures have so far been studied mostly under conventional farming conditions and focus has often been to characterize disease progress of one pathogen. Here we consider simultaneously four important foliar diseases on spring barley grown in organic as well as conventional growing systems. Further, we study the changes in disease severity of variety mixtures when...

Peat mining destroys valuable nature areas and contributes to the greenhouse effect. This warrants the search for alternatives for peat in potting mixes. Composted biowaste could provide such an alternative. An additional advantage of (partially) replacing peat by compost is the increased disease suppressiveness. In this study, nine commercial composted biowastes were tested for disease suppressiveness using the pathosystems Pythium ultimum-cucumber, Phytophthora cinnamomi-lupin and Rhizoctonia solani-carrot. Increased disease suppression was found in compost-amended potting mixes for all three pathosystems. The level of disease suppression ranged from slight stimulation of disease to strong suppression. Suppressiveness against one disease was not well...

Disease-resistant vi ne varieties as a tool to minimize the use 01 copper
Provedor de dados: 21
Autores: Basler, Pierre.
Due to the climatic conditions in some viticultural areas of Switzerland, where the annual rainfalilies between 1000 and 2000 mm, the selection of the vine cultivars for organic viticulture encounters very strong restrictions with traditional European varieties. These cir-cumstances necessitate numerous routine sprayings with fungicides. Therefore there is an increasing interest among both, organic and non organic wine growers, to use, to a certain extent, less susceptible vine cultivars. According to the site, the year, the trellising system, the management and the cultivar selected, these vines need much less or even no fungicide treatment. Blind wine tastings show that the sensoric judgment and the acceptance of wines from interspecific cultivars are...

Direct marketing represents traditionally an important method of sale for organic agri-culture. Added value remains on farm and this form of marketing serves as attribute to strengthen trust and image and to maintain proximity to the customer. Direct market-ing however is losing market shares against competing places of sale in a growing organic market. By analysing panel data and an additional survey with the panel participants it can be seen that a large share of customers think that they were buying organic products, but in reality bought conventional products. Organic farmers should therefore improve their communication with consumers. A large discrepancy between stated and actual buying frequency also advises reconsideration of consumer surveys`...

Dissemination and adoption of bottom-up agriculture to improve soil fertility in Africa: An interdisciplinary approach
Provedor de dados: 21
Autores: Sousa, Fernando; Nicolay, Gian L.; Spurk, Christoph; Adamtey, Noah; Fliessbach, Andreas.
Soil fertility is at stake at a global scale, putting pressure on food security, poverty alleviation and environmental protection, under scenarios of climate change that in most cases aggravate the threat. In sub-Saharan Africa, a combination of depleted soils and population growth adds particular pressure to smallholder farmers and society. Their capacity to innovate in a social, economic, political and cultural context is seen as decisive to reverse the trend of declining soil fertility. However, many technologies with a potential to protect, maintain and build up soil fertility are hardly used by small-scale farmers, triggering the urgent question on their reasoning not to do so.

The study was attempted to measure the role of the key communicators in the dissemination of organic agricultural information in the Tangail district of Bangladesh. The findings of the study revealed that there are six key communicators who are actively working in disseminating organic agricultural information among the ordinary farmers. Among these six key communicators, one is high communicator who usually provide advice and information to ordinary farmers as well as other key communicators. Thus identifying these key communicators from a community, the development organization can train up them and use them successfully in the promotion of organic farming in rural Bangladesh.

Dissolution of cellulosic particles: Population ensemble modeling informs efficient woody biomass processing
Provedor de dados: 21
Autores: Ghasemi, Mohammad; Tsianou, Marina; Alexandridis, Paschalis.
A major barrier to the efficient utilization of biomass is the recalcitrance to dissolution of semicrystalline cellulose. The present study addresses the kinetics of swelling and dissolution of cellulose particles in conditions emulating large-scale processing where the particles exhibit a distribution of size and degree of crystallinity. To this end, we have developed a model in which the behavior of a population of particles is obtained from an ensemble of individual cellulose particle dissolution models. The dissolution of individual solid cellulose particles is based on the relevant transport phenomena and kinetics and reveals decrystallization and disentanglement as two important and potentially rate-determinant steps in the process [1].

Distribution, Abundance and Diversity of Fungal Entomopathogens: Foundations for Conservation Biological Control
Provedor de dados: 21
Autores: Meyling, Nicolai V.
Conservation biological control (CBC) is a pest management strategy in which farming management practices are adopted to enhance the living conditions for specific natural enemies of pests with the specific objective to suppress pest populations. Research in CBC strategies have mostly focused on provisioning of good living conditions for arthropod predators and parasitoids, usually ignoring entomopathogens as regulators of pest populations.     Fungal entomopathogens are widespread in agro-ecosystems and infect a range of arthropod pests, and these fungi should therefore also be included in CBC. Knowledge of the ecology of indigenous populations of fungal entomopathogens is a prerequisite for the evaluation of their contributions to pest control and for...

Distribution chain effects on quality parameters of organically grown tomatoes
Provedor de dados: 21
Autores: Raffo, A; Baiamonte, I; Nardo, N; Nicoli, S; Paoletti, F.
In order to evaluate the effects of short, compared to medium or long distribution chains, on some quality parameters of organically grown fresh tomatoes, a post-harvest experiment was carried out by reproducing in the lab the most common temperature, relative humidity conditions and storage-transport times occurring in the real distribution chain of organic horticultural fresh products.  Organically grown tomatoes of the cv. Nerina harvested at three different ripening stages (mature green, turning, red) were subjected to conditions corresponding to a short (1 day at room temperature), a medium (cold storage for 2 days, followed by ripening at room temperature) and a long distribution chain (cold storage for 6 or 9 days, followed by ripening at room...

Autores: Grohmann, Markus; Winckler, Christoph; Perler, Erika; Isensee, Anne; Christ, Benedikt; Amsler, Zivile; Werne, Steffen; Maurer, Veronika; Heckendorn, Felix.
The aim of this field study was to investigate interactions between gastro-intestinal nematode (GIN) infection, milk performance and age in goats in order to identify animal groups with higher susceptibility to GIN. On 3 farms (farm A: n = 29, farm B: n = 33, farm C: n = 117 milking goats) fecal egg count reduction tests (FECRT) were performed in summer. All 179 milking goats were enrolled in FECRT and individual milk performance was recorded before and after FEC for FECRT. Furthermore, in early summer and autumn bulk fecal samples were cultured for every farm and GIN genera were determined.

Distribution patterns of fungal entomopathogens in soil habitats: Natural occurrence, diversity and dynamics
Provedor de dados: 21
Autores: Meyling, Nicolai V.
Fungal entomopathogens are seemingly ubiquitous in soils. An increasing number of surveys around the world have shown that ascomycete fungi from the Hypocreales can be isolated from soils of many habitats. Based on morphological characteristics of the fungi some patterns of distribution have emerged. However, recent developments in molecular characterization of entomopathogenic fungi have revealed significant new insights into the distribution of genetic groups of some taxa, including Beauveria spp, and possible restrictions to certain habitats. I will present and discuss some of these distribution patterns and include new findings which indicate that some fungi are restricted to underground lifestyles while others cycle between below- and aboveground...

Diverse characteristics of UK organic direct marketing chains
Provedor de dados: 21
Autores: Geen, N; Firth, C; Maye, D; Ilbery, B.
In the past few years, organic direct sales in the UK have grown rapidly. Direct sales are assumed to have short or distinct marketing chains from farm gate to consumer. This paper begins by outlining some current problems with the widely accepted defi nition of organic direct sales and charts some of their diverse characteristics. It goes on to argue that the mix of organic direct and multi-farm direct sales is so diverse that a greater clarification of terms is necessary in order to progress consumer, policy and research understanding.

Diverse swards and mob grazing for dairy farm productivity: A UK case study
Provedor de dados: 21
Autores: Leach, Katharine; Palomo, Gonzalo; Waterfield, William; Zaralis, Konstantinos; Padel, Susanne.
The paper presents first year results of one participatory case study carried out as part of EU FP7 funded SOLID project (Sustainable Organic and Low Input Dairying) on an organic dairy farm managed with diverse swards and mob grazing in Britain. Mob grazing is a livestock management strategy consisting of high stocking density for a short time to remove forage rapidly due to high grazing pressure and then removing livestock to allow grass recovery. On the farm this is combined with a diverse sward, paying particular consideration to soil fertility. First results indicate that there was more available herbage in front of the cows, especially in the summer months, than could be expected from rotational grazing with shorter rest periods. Differences between...

Diversification and specialisation as development strategies in organic farms
Provedor de dados: 21
Autores: Zander, Katrin.
Unsatisfying economic performance, continuous work overload or the entrance of the younger generation are often the starting point for reorientation of the farm’s organisation in order to increase the farm’s efficiency. Theoretically, farmers are faced with two main options when looking for a viable farm strategy: diversification or specialisation. Based on a quantitative and qualitative survey of 40 farms, the results show that the decision to either diversify or specialise is usually a multi-dimensional issue. Only the analyses of the interactions between many different factors may help to understand the decision processes on farms. One central result of the study is that the personality of the farmer is the key driving factor in the decision on...

1 – Introduction   Responding to the many sustainability issues related to modern industrial agriculture (air, soil and water pollution, biodiversity loss, etc.), the diversity argument was brought forward by scientists (Kremen et al., 2012). Diversified farming systems intentionally include functional agrobiodiversity, i.e. crops, seeded and permanent pastures, rangelands and animal genotypes and species chosen by the farmer to manage his farm. These systems presumably provide ecosystem services while reducing the input needed for production. Agrobiodiversity is also assumed to strengthen the robustness and resilience of livestock farming systems.   Because of their inherent complexity, research on diversified farming systems is limited. Literature on the...

Diversifikationsstrategien für das Management der Kraut-und Knollenfäule der Kartoffel
Provedor de dados: 21
Autores: Finckh, Maria R.; Andrivon, Didier; Bodker, Lars; Bouws-Beuermann, Heidi; Corbiere, Roselyne; Elliseche, Daniel; Philipps, Scott; Wolfe, Martin S.
Fazit: Die bisherigen Ergebnisse deuten auf eine extreme Sortenabhängigkeit in den epidemiologischen Effekten von Diversifikationsstrategien hin. Außerdem spielt die Variabilität des Befallsdruckes selbst innerhalb eines Feldes eine kritische Rolle. Für die Auswertung von Daten muß deshalb die räumliche Verteilung des Befalles viel stärker mit entsprechenden statistischen Modellen in Betracht gezogen werden.   Die Ergebnisse aus den Streifenexperimenten sind analog den Ergebnissen aus den Sortenmischungen und deuten darauf hin, daß Kartoffeln extrem empfindlich auf Konkurrenz sowohl verschiedener Sorten als auch Arten reagieren. Um Diversifikationsstrategien sinnvoll einsetzen zu können, sollten als erstes die Reaktionen von Sorten auf andere Sorten und...

Autores: Borgen, Anders.
Modern cereal production has reached a stage of homogeneity, where both environment, nutrition and culinary quality suffers. In order to increase cereal diversity, projects have started investigating heritage varieties, and varieties and species with exotic traits. Well performing varieties and landraces will be used as they are, or will be used as genetic donors in a participatory breeding programme developing composite cross population focussing on disease resistance or special quality traits.

Diversity as a key concept for organic agriculture
Provedor de dados: 21
Autores: Langer, Vibeke; Frederiksen, Pia.
Diversity is a key concept of organic agriculture and is intuitively perceived as having positive, but not always explicit, consequences for the internal functioning of the farm as well as for the impact on environment and farmland nature. In two groups of specialised organic farms (arable and dairy) and a group of mixed farms, links between production diversity and diversity at the scales above and below, as well as relations to potential farmland biodiversity, are examined. Results show that diversity in different scales are not consistently correlated, i.e. neither high diversity in farm household on-farm activities, nor diversity in agricultural production are linked to  high crop and land use diversity. Furthermore, there are no simple relations...

Diversity in measures against infection with avian influenza in organic poultry by different European countries
Provedor de dados: 21
Autores: Bestman, Msc M.W.P.
This paper describes how different European countries prescribe measures for farmers to reduce the risk of infection with avian influenza in poultry. These measures are for example the obliged indoor confinement during so-called risk periods ort the allowance to vaccinate against this virus infection. These measures have consequences for the organic poultry sector. It seems there is a large diversity between the different European countries concerning what prescriptions there are and especially the definitions of risk areas and risk periods seem to vary. The consequence in the Netherlands, for example, is that in 2007, approximately 95% of the organic laying hens were confined during nearly 5 months, while there was no single case of avian influenza within...

Diversity measures in Danish organic farming
Provedor de dados: 21
Autores: Frederiksen, Seniro researcher Pia; Langer, Associate Professor Vibeke.
Farm diversity is usually associated with a mixture of production branches on the farm, and it is often associated with environmetnally "friendliness". In this study focus is on other types of farm diversity, including non-agricultural farm activities and off-farm income. It is explored how frequent these activities are on the organic farms, their economic importance and the respective participation of farmer and spouse. These diversity measures will be related to farm management in the continuation of the study.

The interest of organic farmers for adopting conservation agriculture practices is currently growing. But, there are few technical and scientific references available for organic farmers when they start applying conservation agriculture practices. The main objectives of this study are (1) to explore the diversity of crop management practices using conservation agriculture methods among European farmers, and (2) to identify main farmers’ strategies. We carried out a survey of 159 farmers located in 10 European countries with a questionnaire with closed-ended questions. Data were analysis with a multi factor analysis followed by clustering to identify groups of farmers that share the same type of spring and winter crop managements. Organic farmers in Europe,...

Diversity of organic livestock systems in Europe
Provedor de dados: 21
Autores: Roderick, Steve; Padel, Susanne; Younie, David.
There is significant diversity in livestock production across Europe, as a consequence of a range of climatic, historic and economic factors. Yet there are common standards and goals. Enlargement of the European Union has added emphasis to the importance of this diversity. Statistics representing the recent development of organic farming illustrates the considerable variation across the continent in relation to land use and the main animal species farmed. This paper examines some of the climatic and historical impacts of a diverse Europe and recom-mends a degree of flexibility in the adoption of or-ganic standards.

Diversity promotes production of ryegrass-clover leys through inclusion of competitive forb species
Provedor de dados: 21
Autores: Cong, W-F; Søegaard, K; Eriksen, J.
Highly productive temporary grasslands in Europe are usually composed of only a few plant species, and are typically dominated by perennial ryegrass-clover mixtures. Including additional competitive forb species holds potential for enhancing productivity in temporary grasslands, but requires further demonstration. In a grassland biodiversity experiment, one or all of the three forb species: chicory (Cichorium intybus L.), caraway (Carum carvi L.) and plantain (Plantago lanceolata L.), were grown in different proportions with the perennial ryegrass (Lolium perenne L.)-red clover (Trifolium pratense L.)mixture under two slurry application levels (0 and 250 kg total N ha-1 year-1). Dry matter (DM) yield and botanical composition were determined in 2014 and...

Autores: Wallenbeck, Anna; Lundeheim, Nils; Rydhmer, Lotta.
De djur som används i ekologisk grisproduktion i Sverige idag är selekterade för hög produktion i konventionell miljö.

Det gör vi genom att undersöka om det finns genotyp-miljö-sampel för slaktgrisegenskaper mellan ekologisk och konventionell miljö. Om det finns sådana samspel så är inte de bästa grisarna i konventionell miljö de bästa grisarna i ekologisk miljö och då finns det behov av ett eget ekologisk avelsarbete (Rydhmer m fl, 2003).

Do Farm Management Practices Alter Soil Biodiversity and Ecosystem Function?   Implications for Sustainable Land Management
Provedor de dados: 21
Autores: Philipps, Ms Lois; Stockdale, Dr Elizabeth A.; Waston, Dr Christine A.
Maintaining ecosystem functions is a key issue for sustainable farming, while recent reviews (Hole et al, 2005, Fuller et al 2005) have highlighted that a wide range of taxa, including birds and mammals, benefit from organic management of land, there is a need to bring together the evidence for the impact of agricultural management practices on belowground biodiversity. A focus simply on the biodiversity of below-ground species is however not enough and there is a need to consider the contribution of below-ground biological processes to the maintenance and enhancement of a range of ecosystem services. A recent literature review on the impacts of land management practices on soil ecology and function shows clearly that farm management practices do alter...

Ecological services may be exploited by use of living mulches in intercropping systems for production of vegetable crops. But may high yields be attained in intercropping systems for production of resource demanding crops such as cauliflower? In the frame of the InterVeg (Core Organic II) project, four field experiments were carried out in IT, SLO, DE and DK in order to study the effect of the living mulch introduction in cauliflower based cropping systems on crop yield and yield quality. The preliminary results, obtained after the first year project, showed yield and produces quality equal to those obtained in the sole cropping system if the system is properly managed (i.e. LM is late sown or its growth is controlled by root pruning).

Do Organic Consumers Oppose Genetically Modified Food Stronger than Others? Results of a Consumer Research in Germany
Provedor de dados: 21
Autores: Wirthgen, Antje.
The majority of consumers, in particular European consumers oppose genetic modifi-cation of food. Although consumers oppose strongly genetic modification of food, genetically modified food production increases world wide. The co-existence of both, genetically modified food production and food production free of genetic modification cannot be ensured. There is always a risk that non-genetically modified food gets contaminated despite safety regulations. Thus, even organic production, which is supposed to be free of genetic modification, is endangered and can maybe not ensure to produce food definitely free of genetic modification. Against that background, this consumer research focuses on organic consumers and their attitudes towards geneti-cally modified...

Provedor de dados: 21
Autores: Marian, Livia; Thøgersen, John; Krystallis Krontallis, Athanasios.
The hypothesis of this research is that the impact of quality dimensions on consumers’ willingness to buy organic vs. conventional or free-range chicken is partly mediated through taste expectations. The study comprises two exploratory focus group studies, followed by a questionnaire containing a conjoint analysis design. The purpose of the focus groups was to determine the most important quality cues, which could afterwards be incorporated into the choice experiment. It was found that production method, price, size and information about farmer and rearing conditions are very important quality cues for the choice of chicken, and that taste is one of the most important quality dimensions in consumers’ overall evaluation of chicken. In the next step, the...

Do the opportunity costs of providing crop diversity differ between organic and conventional farms? The case of Finnish agriculture
Provedor de dados: 21
Autores: Huhtala, Anni; Sipiläinen, Timo.
The attractiveness of targeted environmental policies on farmlands depends crucially on the  opportunity costs of the conservation programs. We use a crop diversity index as an indicator of  environmental output to compare the efficiency of conventional and organic crop farms. Technical  efficiency scores are estimated by applying data envelopment analysis to a sample of Finnish farms  for the period 1994 – 2002. We also estimate shadow values, or the opportunity costs, of producing  crop diversity. Our results show that there is variation in the shadow values between farms and the  technology adopted. The findings provide a basis for designing cost-effective policy instruments  such as auctions for conservation payments.

Do we pay proper attention to the subsoil C turnover?
Provedor de dados: 21
Autores: Olesen, J.E.; Petersen, B.M.
The Kyoto Protocol allows carbon sequestration from changes in agricultural land use to be a mechanism for reducing anthropogenic greenhouse gas emissions. There is a specific requirement in the protocol for verification of the sequestration estimates, which may often involve the use of soil carbon simulation models and thus puts a large requirement on the validity of these models.     The commonly used soil organic matter models have been calibrated on the basis of measurements of topsoil C contents under the implicit assumption that there is negligible vertical transport of soil C. We demonstrate this assumption to be wrong, and that it may lead to large deviations when modelling long-term soil organic matter development. Therefore a model with a net...

Within this project we assess whether wildflower strips and companion plants increase the control of cabbage pests Plutella xylostella L. (Lepidoptera: Plutellidae), Mamestra brassicae L. (Lepidoptera: Noctuidae) and Pieris rapae L. (Lepidoptera: Pieridae) by (1) naturally occurring parasitoids and predators and (2) mass‐releasedn Trichogramma brassciae (Bezdenko) (Hymenoptera: Trichogrammatidae) parasitoids. Two organic cabbage fields were used for this study: adjacent to each field a wildflower strip was sown and companion plants (Centaurea cyanus L. (Asteraceae)) intermixed within the crop. Within each field ~15,000 M. brassicae eggs were placed out to determine the parasitism rates by mass‐released T. brassicae and to assess the levels of egg...

Do you like organic wine? Preferences of organic consumers
Provedor de dados: 21
Autores: Janssen, Meike; Zander, Katrin.
The market share of organic wine is remarkably lower than the market share of organic food in general. The objective of this paper was to analyse the wine preferences of consumers of organic food in Germany in order to identify how demand for organic wine could be increased. Choice experiments and structured interviews were conducted with 600 consumers of organic food. In the choice experiments, the participants clearly preferred organic wine over conventional wine. However, preferences for organic wine were lower among people with a high interest in wine, i.e. people who place high importance upon vintage, grape variety and winery. We conclude that targeted marketing activities are needed to convince these people about the quality of organic wine....

DOC and DON from grass-clover - results from a field experiment
Provedor de dados: 21
Autores: Rasmussen, Jim; Høgh-Jensen, Henning.
The C and N dynamics in perennial grass-clover mixtures are not fully understood although such mixtures dominate temperate grassland. The co-existence of clover and grass involves both competition for and transfer of nutrients between the species. The nutrients that are competed for and transferred may originate from leaky root systems, from a rapid turnover of the fine root systems, or from degradation of more stabile organic material.    The aim of the present study was to investigate the origin of dissolved organic C and N in perennial grass-clover mixtures. In an existing grass-clover ley, field mezotrons (cylinders with a diameter 30 cm) were installed in the spring of 2003 to depths of 20, 40 and 60 cm. Suction cups was installed beneath the...

DOC trail: soil organic matter quality and soil aggregate stability in organic and conventional soils
Provedor de dados: 21
Autores: Fliessbach, Andreas; Hany, Roland; Rentsch, Daniel; Frei, Robert; Eyhorn, Frank.
Conclusion  Soil organic matter quality is affected by the agricultural systems of the DOC trial. System effects on the chemical composition, however, were smaller than those on the living organisms in soil and their functions. A close correlation was found between soil structure and microbial biomass indicating that microbes are playing an important role in soil structural stability.

DOC-trail: 20 years of organic and conventional farming affect soil microbial properties
Provedor de dados: 21
Autores: Oberholzer, H.R.; Mäder, Paul; Fliessbach, Andreas.
In a long-term field trial (DOC; = bio-Dynamic, bio-Organic, Conventional) at Therwil, Switzerland, agricultural production systems have been compared since 1978. The production systems differ mainly in the amount and form of fertiliser and plant protection strategy. Crop rotation and soil tillage were the same. In the most prominent systems soil microbial properties were investigated for the first time after two crop rotations in 1990. In 1998, after 3 crop rotations, soil microbial properties were investigated in all field plots.  Conclusions  Agricultural systems exert distinct effects on chemical and microbiological soil properties, prominently the bio-dynamic system with the application of composted manure. Part of the influence on microbiological...

The health of weaned pigs should be described using several information sources to get an overall assessment of the health state in the herd. In this case study four organic pig herds each fattening between 800 and 3500 pigs per year provided data from clinical examination of a sample of animals, pathological findings at slaughter, post weaning mortality and medicine usage in the herd. Clinical symptoms were present in 8 – 18 % of the pigs, and 2 – 6 % of the pigs showed more serious symptoms of disease. At slaughter 10 – 17 % of the pigs got remarks for pathological lesions, primarily liver spots, abscesses and chronic pericarditis. The post weaning mortality varied between herds, while the usage of medicine was rather low in the herds. The herd health...

Does early spring grazing stimulate spring grass production?
Provedor de dados: 21
Autores: Eekeren, N. van; Rietberg, P.I.; Iepema, G; Wit, J. de.
Early spring grazing may stimulate grass growth in spring by increasing grass root exudation, which enhances mineralization. The objective of this study was to investigate the net effect of early spring grazing on spring grass production. Therefore, we conducted two field experiments on production grasslands. Simulated early spring grazing negatively affected the yield of the first cut: compared to ungrazed plots on sandy soil an a tendency on clay soil, dry matter yield of early-plots was reduced by 20% (sand, P=0.009) and 12% (clay, 0.062), respectively. These differences were partly compensated in later cuts. Despite the negative effect on grass yield of the first cut, early grazing positively affected the crude protein (CP) content of the grass in the...

Does modelling of spatial heterogeneity matter?
Provedor de dados: 21
Autores: Hutchings, Nicholas J.; Petersen, Bjørn M.; Olesen, Jørgen E.; Berntsen, Jørgen.
The presence of grazing animals contributes to a much greater spatial heterogeneity in the cycling of C and N within grasslands, compared to arable land. This is primarily due to the deposition of excreta in patches rather than evenly over the field. However, an additional source of heterogeneity is introduced because grazing animals do not evenly utilise the grassland. Herbage contaminated by their faeces will tend to be rejected, as will poor quality (low digestibility) vegetation. There is therefore good reason to expect that C and N cycling will be highly spatially variable in grazed grassland. Hitherto, grassland models have assumed C and N dynamics to be uniform within a field. In this paper, modelling is used to investigate the potential effect of...

Does nose ringing make any sense?
Provedor de dados: 21
Autores: Studnitz, M.; Eriksen, J.; Strudsholm, K.
Outdoor sows are nose ringed to maintain grass cover. Intact pasture insures the sows possibility to graze and is also assumed to reduce the nutrient leaching. However, no evidence of reduced leaching from fields with ringed sows is available. Rooting behaviour constitutes an essential part of the sows’ natural behavioural repertoire. In organic husbandry it is an established aim to consider the animals’ natural behaviour, and by allowing nose ringing in organic pig production the natural behaviour of the animals has been prevented in order to consider the environment. The purpose of this experiment was to relate grazing and rooting activity of sows to grass cover and nutrient leaching. Three treatments were tested on 78 sows in total: 1: sows with nose...

Does organic farming achieve environmental goals efficiently?
Provedor de dados: 21
Autores: Jacobsen, Lars-Bo.
Concerns about the impact of modern agriculture on the environment have in the past few decades resulted in strict legislation concerning the leaching of nitrogen from Danish farms and their use of pesticides. An often-heard argument in recent years is that conversion to organic farming is a solution to many environmental problems. Hence, in the late 1990s several initiatives to support the development of organic farming have been taken among others permanent direct support for producing organically. This was made possible by the 1992 reform of the common European Agricultural Policy that allowed for specific subsidy for environmental friendly production.   This paper discusses the cost efficiency of two alternative policy measures for obtaining an overall...

Does Organic Farming have Greater Potential to Adapt to Climate Change?
Provedor de dados: 21
Autores: Niggli, U.; Hepperly, P.; Fliessbach, A.; Maeder, P.
Agricultural production in most parts of the world will face less predictable weather conditions than mankind experienced during the intensification of agriculture over the last century. Especially South Asia and Southern Africa could suffer negative impact on several crops when no investments will be made into improved adaptiveness of the production systems. Besides specific technical measures (irrigation, breeding for drought improved or heat tolerant crops), the resilience of whole production systems is a very important focus.    Organic agriculture is a highly knowledge-based technique for manipulating complex agro-ecosystems, for breeding locally adjusted seeds and livestock, and for producing on-farm fertilizers and inexpensive nature-derived...

DOES ORGANIC FOOD INTERVENTION IN SCHOOL LEAD TO CHANGED DIETARY PATTERNS?
Provedor de dados: 21
Autores: He, Chen; Mikkelsen, Bent Egberg.
During adolescence food habits, physical activity, and life style of young people are easily influenced by a number of actors and phenomena in the environment including parents, friends, advertisements and all of the changes occurring in society. The meal patterns formed during adolescence will be continuously influenced into their adulthood even following generations in the future. Since school increasingly is taking a role in both food provision and in health, environment and nutrition education of young people by implementing healthy and environmental friendly policies, it is relevant to investigate the relation between the different components of such interventions. In other words it is relevant to ask the question: does organic food supply police go...

Does regional organic screening and breeding make sense? To answer this question we looked for experimental evidence in an organic outdoor tomato project. Potentially suitable varieties were collected, genotype x environment interactions were investiga-ted and selection was carried out within three crosses at three farms in Central and Northern Germany. The resulting selections were compared at all farms. Screening within organic horticulture was the most important means of finding suitable varieties. After three years of evaluation, 71% of the 18 most successful varieties came from colleagues within organic horticulture. The analysis of the regional evaluation did not reveal strong interactions of varieties and locations. The rate of Phytophthora (late...

All over the world, Thule III is used as differential variety for the resistance gene Bt-13 against common bunt. It can therefore be strange that I can question whether Thule III have Bt-13, so let me elaborate the question. I also use Thule III as a standard for Bt-13, and I got this variety from GRIN PI 181463. This variety does indeed have a major gene against common bunt and since we all use it as a standard for Bt-13 this gene is per definition Bt-13. What still puzzles me is that this variety does not look like Thule III. It says in the GRIN database that it is of Swedish origin with the pedigree Thule II/Sammet. PI 181463 is a short, lodging and weak variety with a very poor winter hardiness, and it does not at all look like a Swedish winter wheat....

Wheat (Triticum aestivum L.) cultivars may have differential effects on soil microbial communities and the breadmaking quality of harvested grain. We compared six Canadian spring wheat cultivars under organic and conventional management systems for yield, breadmaking quality and soil phospholipid fatty acid analysis (PLFA) profile. Yields were lower, but protein levels were higher in the organic system. Cultivars differed for quality traits, but all cultivars had acceptable levels for processing. There were small differences in PLFA profiles for cultivars in the conventional system, but none in the organic system. More significant correlations between grain quality and PLFA measures were present in the organic system. Protein levels and breadmaking quality...

Fjärilarna utgör ett stort problem inom livsmedelsindustrin eftersom deras larver äter och förstör produkterna. Födodofterna skulle kunna användas i fällor för att locka till sig befruktade fjärilar, vilket leder till färre larver i produkterna och mindre skada. Det borde också vara möjligt att övervaka skadedjurspopulationer med hjälp av dofterna för att kunna ta beslut om när bekämpningsåtgärder ska sättas in.

Sustainable consumption and production (SCP) is a topical concept as national SCP programmes have been drafted by several countries around Europe. This discourse analysis, based on interviews with Finnish SCP committee members, suggests that sustainable consumption and production can be a useful concept for approaching economy in a down-to-earth manner. It can enrich the environmental policy agenda that has long been dominated by technology-oriented ecological modernization. A critical point is, however, that the SCP depate is more concentrated on the needs of consumers than on the needs of poor, the initial focus of sustainable development. Moreover,ideas on how to really change consumption patterns seem to be scarce, scattered, and also contradictory...

Driftsmåte og engalder påvirker melkekvaliteten
Provedor de dados: 21
Autores: Adler, Steffen; Steinshamn, Håvard; Jensen, Søren K.
Fettsyresamensetning og innhold av vitaminer i melk ble i stor grad påvirket av sesong og produksjonssystem og i mindre grad av engalder. Beitesesongen hadde gunstig effekt på fettsyresammensetning sammenlignet med innefôringsperioden, mens økologisk driftsform hadde gunstige effekter som økt andel av C18:3c9,12,15 og negative effekter som økt andel mettede fettsyrer. Hovedfaktorene bak de observerte effektene antas å være fôrrasjonens andel av kraftfôr, beiteopptak, rødkløver og kraftfôrets innhold av lipider.

Autores: Wittwer, Raphaël; Tombez, Grégoire; van der Heijden, Marcel.
Ein besseres Verständnis der Dynamik hinter der Freisetzung von pflanzenverfügbaren Nährstoffen aus Boden oder organischen Dünger und eine Verbesserung der Nährstoffverwertung von Ackerfrüchten sind zwei wichtige Herausforderungen, um die Produktivität im ökologischem Ackerbau zu erhöhen. Doch diese Prozesse sind stark sowohl von biotischen (z.B. Bodenmikroben) als auch abiotischen (z.B. Temperatur, Niederschlag, Bodenfeuchtigkeit, Bodenstruktur) Faktoren beeinflusst und erschweren effiziente Untersuchungen. Fernbilderkundung-Technologien (remote sensing) haben sich in den letzten Jahren stark weiterentwickelt und bieten heute neue Ansätze und Methoden, um der Ernährungsstatus von Pflanzen sowie die Dynamik des Pflanzenwachstums nicht destruktiv zu...

Dropping organic certification - effects on organic farming in Norway
Provedor de dados: 21
Autores: Koesling, Matthias; Løes, Anne-Kristin; Flaten, Ola; Lien, Gudbrand.
From 2002 to 06, the annual dropout rate of certified organic farmers averaged 7.3%. A project was started in 2007 to explore farmer’s reasons for opting out of certified organic production. Important factors seem to be public regulations including standards for organic farming, agronomy, economy, and farm exit. While many organic farmers with relatively small holdings have opted out, farmers with more land and larger herds tend to convert to organic agriculture. The trend towards larger-scale farms in organic than in conventional agriculture, encouraged by the design of the organic farming payments, challenges the organic principles of diversity and fairness. Means should be considered to ensure that small organic enterprises are also economically viable.

Drosophila suzukii control using Kaolin, lime and rock dusts.
Provedor de dados: 21
Autores: Strack, Timo; Cahenzli, Fabian; Daniel, Claudia.
The Spotted wing drosophila, Drosophila suzukii, is an invasive pest in Europe and North America, infesting various soft-skinned fruits. Because D. suzukii attacks ripening fruits shortly before harvest, only insecticides with short pre-harvest intervals can be applied. Alternatively, kaolin, lime and rock dusts are non-toxic to non-target organisms, but the whitish coating on fruits potentially deters oviposition of D. suzukii. Therefore, we tested oviposition deterrence and insecticidal effects of such substances. Female D.suzukii flies were exposed to treated blueberries under laboratory conditions for 24 hours. Kaolin, clinoptilolite, clinoptilolite + Heliosol (pine-oil based wetting agent) and calcium carbonate significantly reduced oviposition,...

Dry matter yields and quality of organic lupin/cereal mixtures for wholecrop forage
Provedor de dados: 21
Autores: Azo, W M; Lane, G P F; Cannon, N C; Davies, W P.
In view of climate change predictions and the general desirability of increasing the amount of home grown protein, a case exists for the investigation of lupins and lupin/cereal bicrop combinations as wholecrop forage on organic farms. A replicated randomised block trial is described which took place at the Royal Agricultural College, Cirencester, in 2005. This involved spring sown blue, white and yellow lupins, millet, wheat and triticale and lupin/cereal bi-crops. Data for dry matter yields for wholecrop silage, crude protein, MAD fi bre content and estimated ME, are presented for a single harvest. It is concluded that white lupins and white lupin bi-crops with spring wheat or triticale offer the best prospects for a viable wholecrop forage crop in an...

Drying behavior of organic apples and carrots by using k-means unsupervised learning
Provedor de dados: 21
Autores: Roberto, Moscetti; Serena, Ferri; Andrea, Colantoni; Riccardo, Massantini.
Drying prevents food spoilage and decay through moisture removal due to simultaneous heat and mass transfer from food, which may be stored for long period with minimal deterioration occurring. However, drying technology is not always paired with good/excellent organoleptic, nutritional and/or functional properties of food. In fact, during drying the heat-sensitive substances are often destroyed and degradation processes may be exacerbated due to various and concurrent reaction mechanisms. Based on authors’ best knowledge, drying degradation kinetics of biological materials are usually pseudo first-order or first order reactions (i.e. carotenoids degradation in carrots) and may be affected by the initial quality of the product itself. Therefore, the main...

Drying of fresh organic beef with differnt pretreatments
Provedor de dados: 21
Autores: von Gersdorff, GardisJ.E.; Crichton, StuartO.J.; Retz, Stefanie K.; Hensel, Oliver; Sturm, Barbara.
Drying of foods is one of the oldest food preservation techniques, but it gains particular importance when regarding food quality and shelf life. Meat snacks are of growing interest because they are high in protein but low in fat and carbohydrates. In organic food production the use of preservatives is limited, and for this reason product specific drying strategies and pretreatments are essential. In this study fresh beef slices were treated with salt (0,5 % and 1 %) and salt and vinegar (0.5% and 5 %) and were dried at 70 °C in a convection dryer. Moisture content and color were measured during the drying process alongside visual to near infra-red hyperspectral images of the slices. The optimal wavelengths for moisture content and color were determined...

Provedor de dados: 21
Autores: van der Heijden, Marcel; Bender, Sophia; Wagg, Cameron.
This work demonstrates that soil biodiversity plays an important role in agroecosystems. The presence of an enriched soil community in large outdoor lysimeters  enhanced plant yield and reduced nutrient leaching losses. Moreover, soil biodiversity loss and simplification of soil communities reduced ecosystem multifunctionality.  Further analysis revealed that promotion of soil biodiversity and soil ecological engineering can help to reduce the reliance on external inputs and is especially  suitable for a transition to organic agriculture. This work points to the need to support soil life for a sustainable agriculture.

Dual roles of spent mushroom substrate on soil improvement and enhanced drought tolerance of wheat Triticum aestivum
Provedor de dados: 21
Autores: Liang, Song; Chiu, Siu-Wai.
This study examines the effects of the spent substrate of oyster mushroom (SMS) for growing wheat at different drought conditions. The SMS not only served as the sole fertilizer to produce normal growth and grain yield of wheat but also improved the soil quality after harvest to raise the soil organic matter, maintain the soil alkalinity and increase field capacity unlike the synthetic fertilizer amendment. Simultaneously, SMS treatment enhanced drought tolerance of wheat by enabling germination at 8.5% soil water content and completing sexual reproduction to grain production even at 6.3% soil water content.

High nitrous oxide emissions are reported in literature when grass-clover is mulched in stockless farming systems. In our study, we measured similar emission rates especially after intensive rainfall when shoot biomass of grass-clover is transferred to maize and celeriac as a source of plant available nitrogen. Inefficient use of nitrogen bound in this mulch may furthermore result in nitrate leaching, especially if harvest is late and bare fallow over winter unavoidable.

Autores: Buder, Dipl.-Soziologe Fabian; Hamm, Prof. Dr. Ulrich.
Using purchase data from household panels, this paper analyses consumption patterns  over four years for different groups of consumers. Results show that although a  rising number of households purchases organic food, the market growth is still mainly  carried by a small group of heavy users. Comprising about 20% of the customers and  about 65% of the organic market share, this group shows the most stable behaviour  over time. The development of the organic budget share of this group also shows no  signs for an end to the growth. Nevertheless suppliers should also evaluate the special  needs and wishes of 65% of households (2007) which only purchase organic food  from time to time.

Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik.
Der bliver stillet stadig større krav til den økologiske fodring. En større og større del af foderrationen skal være økologisk. Og reglerne sætter samtidig nye og mere restriktive grænser for brug af fiskemel, kødbenmel og sojaskrå.  Det betyder, at økologiske landmænd har brug for nye fodermidler med et højt og særlig værdifuldt indhold af proteiner. For danske planteavlere er det derfor en udfordring at kunne levere økologiske proteinafgrøder. Hvorfor importerer råvarerne til en dansk økologisk produktion, hvis vi selv kan dyrke dem herhjemme? Med de sager om fejl og snyd ved import af økologiske råvarer, der dukkede op i løbet af 2001, er spørgsmålet ekstra relevant.

Dyrkningsforholdenes indflydelse på bagekvaliteten
Provedor de dados: 21
Autores: Pedersen, L.
Dyrkningsforholdenes indflydelse på bagekvaliteten.  Bagekvalitet af hvede afhænger af den kemiske sammensætning af korn og mel, hvor glutenproteinernes mængde og sammensætning har en stor betydning. Glutenmængde og egenskaber er dels genetisk bestemt gennem valg af sorten, men dyrkningsbetingelserne , herunder gødskningsform og mængde, har ligeledes stor betydning. Ved dyrkning af økologisk brødhvede hvor næringsstoftilførselen kan være begrænset i en del af vækstperioden, ses derfor en stor variation i hvedens bagekvalitet. Det er derfor vigtigt, at fastlægge dyrkningsstrategier, der ved økologiske dyrkningsforhold resultere i brødhvede med god bagekvalitet.  Fra dyrkningsforsøg med vårhvede gødet med henholdsvis organisk og mineralsk gødning, er der...

Dyrkningssystemernes effekt på produktion og miljø
Provedor de dados: 21
Autores: Olesen, Jørgen E.
Moderne landbrugssystemer har en kraftig indflydelse på det omgivende miljø, og i Danmark er der særlig fokus på nitratudvaskning og drivhusgasemissioner fra landbruget. På det globale skala er lattergas (N2O) en af de væsentlige drivhusgasser (Mosier et al., 1998), og i Danmark er landbruget langt den største kilde til udledning af lattergas. Der stilles i stigende grad krav til landbruget om-kring reduktion af drivhusgasudledningerne, og tiltag til reduktion af udledningerne af N2O og me-toder til lagring af kulstof i jorden er derfor påkrævede. Bæredygtige landbrugssystemer skal også opfylde behovet for tilstrækkelige mængder og kvalitet i fødevarerne. Økologisk jordbrug har visse fordele i disse sammenhænge, men der er også behov for forbedringer.    I...

Early or Normal Cut Grass Silage for Dairy Cows in Organic Farming
Provedor de dados: 21
Autores: Adler, Steffen A.; Randby, Åshild T.
Early cut organic grass silage (roundbales) was compared with silage harvested 17 days (180 daydegrees) later in a continuous production experiment with 32 Norwegian Red dairy cows in early lactation. The experiment was carried out in Bodø, Norway. A half of the  cows received a feed ration with 40% concentrates (H), and the other half 10% (L) on an annual energy basis. Feeding early cut silage of an organic ley increased feed intake, milk yield and milk protein concentration compared with normal cut. Left-overs of concentrates were a problem in the experiment and ways to improve the palatability of  on farm produced cereals have to be developed. Early cut crop yields were only about half of the crop yield at normal cut. Therefore early cut may only be...

Autores: Köhler, Anna-Sophie; Huber, Julia; Wolfrum, Sebastian; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
The aim of this study conducted at the experimental farm in Scheyern, was to investigate whether earthworm population in different habitats and under different farming systems (organic vs. integrated) differs. Arable land was compared with alley cropping systems, with meadows and field margins. For comparison purpose there were also investigations on the natural habitats fallow, forest and forest edge. The field study yielded the following results: In the meadow, the tree row in the alley cropping system and in the natural reference habitats (with exception of the studied forest), the abundance and species diversity was enhanced compared with arable land. In addition the tree rows in the alley cropping system had a positive effect on the earthworm...

ECOFRIENDLY NUTRIENT MANAGEMENT PRACTICES FOR YIELD AND QUALITY OF BANANA
Provedor de dados: 21
Autores: Somasundaram, Eagan; Kuttimani, R.; Velayudham, K.
Banana owing to its large size and rapid growth rate require relatively large amount of nutrients for higher yield of quality fruits and it is estimated that 50 tonnes of banana in one hectare removes 320kg N, 32kg P2O5 and 925 kg K2O every year (Lahav and Turner, 1983). Application of inorganic fertilizers though increases the yield substantially but could not able to sustain the fertility status of the soil (Bharadwaj and Omanwar, 1994) and have caused several undesirable consequences in the fragile soil eco-system, leading to gradual decline in productivity. Considering the present situation of soil quality and environmental security, it is necessary to go for an integrated nutrient management, involving various sources of organic manures, organic cakes...

Eco-Labelling, the State and Consumer Confidence
Provedor de dados: 21
Autores: Sønderskov, Kim Mannemar; Daugbjerg, Carsten.
Trustworthy eco-labels provide consumers with valuable information on environmentally friendly products and thus promote green consumerism. But what makes an eco-label trustworthy and what can government do to increase consumer confidence? The scant existing literature seems to argue that low governmental involvement increases confidence. According to this, government should just provide the basic legal framework for eco-labelling and leave the rest to non-governmental organizations. However, the empirical underpinning of this recommendation is insufficient. This paper analyses consumer confidence in different organic food labelling regimes with varying degrees of governmental involvement. Using unique and detailed survey data from USA, United Kingdom,...

Ecological and agronomic evaluation of crop rotations in organic farming systems
Provedor de dados: 21
Autores: Bachinger, Dr. Johann; Stein-Bachinger, Dr. Karin; Fuchs, Sarah.
The integration of nature conservation measures in organic farming requires special know-ledge about potential goal conflicts between ecological and agronomic requirements. The aim of this paper is to introduce a generation and evaluation tool for crop rotations that allows an assessment of the complex interdependencies of different biotic and abiotic parameters. The interdisciplinary ‘Nature Conserva-tion Farm Brodowin’ project provides the experimen-tal basis for developing practical solutions and compromises in this context. Two generated six-course crop rotations are presented as examples of this approach. The results show the sensitivity of the evaluation tool and its usability for improving crop rotations with regard to nature conservation

Ecological footprint could be a tool for evaluating impacts of different agricultural production systems (PS). Based on more years field experiments producing vegetables and field crops cological footprint of conventional (CON), integrated (INT), organic (ORG) and biodynamic (BD) farming systems in Maribor and CON, INT and ORG in Dolenci was calculated and interpreted using the SPIonExcel tool. Results showed a markedly lower ecological footprint of ORG and BD systems compared to CON and INT which are not significantlly different. Identified were possibilities for reducing ecological footprint – for CON and INT by reducing mineral fertilizers and pesticide inputs; for ORG and BD by changing fuels and reducing maschinery use.

Earthworms have long been recognized for their soil engineering capacities. Since the creation of the ecosystem service concept the utilitarian perception of nature has gained a lot of attention and funding for research. Hence, we selected earthworms and their burrowing activities to enable an assessment of their influence on water movement and nutrient release. The study went on in autumn where earthworm population densities and their burrowing activities were quantified in plots of third year clover-grass crops differing in fertilisation and the manner of removing the biomass either by grazing or cutting. We found very high biomasses as expected for clover-grass about 200 g wet earthworm weight m-2. The common earthworm association typical to our region...

Autores: Schader, Christian.
The request for quantitative tools for ecological-economic impact assessment of agricultural policies has increased in recent years, due to i) improved impact assessment and policy evaluation standards of the new agricultural support schemes (European Commission, 2004) and ii) the improved methodological and technical potentials in the field of sector modelling (Heckelei, 2002).  Switzerland, as a non-EU member, has introduced cross-compliance rules already in 1998 and linked a bulk of further ecological direct payments to specific farm management restrictions. While the whole direct payment system has been subject to an official evaluation process (Flury, 2005), especially the question for the cost-effectiveness of extensification policies has not been...

Autores: Schmutz, Ulrich; Firth, Chris; Rayns, Francis.
Research draws on an organic research farm site in central England with a temperate zone climate - fairly common for the northern lowlands of Europe. The soil type is a sandy loam with 591 mm rainfall. Detailed economic and agronomic data have been collected since conversion began in 1995. The economic analysis discusses rotational gross and net margins of more than 30 different rotations with different fertility building and vegetable crops (potatoes, cabbages, onions, carrots, leeks and parsnips). Sensitivity and risk analysis of key variable costs important for successful organic vegetable production are shown. Rotational gross margins varied from –570 €/ha to 6,341 €/ha. Highest output-risk was introduced by yield variations, not price variation....

Economic and environmental analysis of the introduction of legumes in livestock farming systems
Provedor de dados: 21
Autores: Reveredo Giha, C; Topp, C F E; Toma, L; Wu, L.
Legumes in low input systems are becoming increasingly important. The socioeconomic implication of the adoption of novel legumes species has been assessed in sheep and dairy cattle grazing systems in Europe using a biological model which has been linked to linear programming models. In the economic sub-model, the mathematical programming models produce an economic evaluation of the legumes in a farming system context, emphasising the land allocation and the availability of nutrients during the different seasons of the production cycle. Then the paper evaluates the impact of adopting the legumes on the regional income and production. In the UK and Germany, the introduction of legumes results in sizeable gains for the farmers whereas in Italy and France the...

Economic aspects of the application of different organic materials as N-sources in organic production of lettuce
Provedor de dados: 21
Autores: Cabilovski, dipl ing Ranko; Manojlovic, Prof Maja; Bogdanovic, Prof Darinka; Bavec, Prof Martina.
In a field experiment on a farm registered for organic production, we studied the effect of the application of different organic materials (OM): farmyard manure (FYM), guano (G), soybean seed (S), forage pea seed (P) on lettuce yield. Besides yield, we also analyzed the economic profitability of the application of different OM. Fresh lettuce yield was significantly higher with OM treatments than with the treatments without fertilization. The highest yield was obtained with the FYM treatment (43.7 t ha-1), and the lowest with the application of P (42.0 t ha-1). The highest additional profit was obtained with the FYM treatment (1123 EUR ha-1) and the lowest with the application of P (475 EUR ha-1).

Economic Effects of Organic Production in Finland
Provedor de dados: 21
Autores: Viitaharju, Leena; Kujala, Susanna; Törmä, Hannu.
Money is usually one of the strongest reasons influencing decision making when choosing between organic and conventional production or usage, both in case of producers and decision makers of municipalities. The results of the survey directed to organic producers in Finland implied that the contribution to profitability of organic farming would be the most effective way to get more farmers to make the decision to convert from conventional to organic production. Naturally there are also many other reasons that affect the decision to make the conversion, for example environmental and health issues. According to the survey targeted to municipalities’ decision makers, municipalities would use more organic products if they had more financial resources in use....

Economic Evaluation of Longevity in Organic Dairy Farming
Provedor de dados: 21
Autores: Horn, Marco; Knaus, Wilhelm; Kirner, Leopold; Steinwidder, Andreas.
The aim of this study was to highlight the economic importance of longevity in organic dairy cattle husbandry. Performance and reproductive data of 44,976 Austrian organic Simmental dairy cows were analysed by applying a bio-economic model. A farm scenario as well as different market situations were modelled. Overall costs declined with increasing longevity, due to dropping replacement costs. Annual profit was influenced considerably by milk yield and longevity. Short-lived animals needed substantially higher annual milk yields than long-lived animals to achieve equal annual profits. The applied market scenarios showed an increasing importance of longevity in situations of increasing economic pressure (+20% of concentrate price). It has been proven that...

Die Übernahme der Gemeinsamen Agrarpolitik in den neuen Mitgliedsländern im Jahr 2004 geht auch für ökologische Betriebe mit weit reichenden Änderungen der einzelbetrieblichen Förderung einher. Die Modellrechnungen zeigen, dass sich aufgrund deutlich steigender Förderprämien die wirtschaftliche Situation ökologischer Betriebe in ausgewählten Mittel- und Osteuropäischen Ländern bis 2013 erheblich verbessern wird. Dies kann neue und verbesserte Absatzmöglichkeiten auf europäischen Märkten eröffnen. Eine nachhaltige Entwicklung des ökologischen Landbaus in diesen Ländern erfordert jedoch dringend die Entwicklung von Verarbeitungs- und Vermarktungsstrukturen sowie einheimischer Märkte für ökologische Produkte.

Economic profitability of organic vs. conventional cotton-based production systems in a long-term field trial in India
Provedor de dados: 21
Autores: Forster, D.; Andres, C.; Verma, R.; Zundel, C.; Messmer, M.; Mäder, P.
The debate on the relative benefits of conventional and organic farming systems is more topical than ever. The achievements of conventional high-input agriculture were largely brought about at the cost of deteriorating soil fertility; furthermore, they were based to a large extent on fossil fuels. Developing more sustainable farming practices on a large scale is of utmost importance.  However, information about the performance of agricultural production systems under organic and conventional management in tropical and subtropical regions is largely lacking. This study aimed to assess agronomic and economic data from a long-term farming systems comparison trial under semi-arid conditions in central India.

Abstract: Organic farming is becoming more and more popular among Polish farmers. In the year of the accession of Poland to the European Union, the number of certified organic farms amounted to 1683. By the end of 2005, which is after the first year of Poland’s membership in the EU, the number of farms practicing exclusively organic farming or taking up that course of production amounted to more than 7000.   On the basis of agricultural accountancy from 2004, an economic and production evaluation of 110 organic farms included in the Polish FADN sample was carried out. The organic farms were classified into 5 classes of economic size. 92% of them were of economic size below 16 ESU. The study contains economic and production results achieved by a group of...

Autores: Häring, A. M.
The objective of this paper is to introduce, based on own practical experiences, an approach to agricultural policy research that is based on intensive interaction with groups of farmers, and to discuss to which extent participation is realised in this process. This approach consists of panels of farmers, scientists and agricultural advisors. In group meetings development strategies of typical organic farms and the farms reaction to changes in the policy environment are discussed on a regular base. Farmers are consulted on their opinion and define potential farm development strategies in a cooperative manner, whereas the scientist analyses data. The potentials of this cooperative approach of consultation are discussed in the light of research objectives...

Autores: Lohr, Luanne.
This case study reviews the economic, social, and environmental benefits associated with organic agriculture in the United States. Measurable impacts are quantified by comparing indicators of benefits in counties with organic farms and counties without. Statistical differences across counties with and without organic farms provide preliminary evidence that organic farms may generate a variety of direct and indirect benefits. Of 36 indicators tested across a range of economic, social, and environmental benefits, 26 favor organic systems, three favor conventional systems, and seven are neutral. Even though organic farmers are not a large percentage of the total number of U.S. farmers, they may be influencing mainstream agriculture to shift toward greater...

Economic sustainability and risk efficiency of organic versus conventional cropping systems
Provedor de dados: 21
Autores: Lein, G; Hardaker, J B; Flaten, O.
Environmental, social and economic attributes are important for the sustainability of a farming system. Resilience is also important yet has seldom been directly considered in evaluations of economic sustainability. In economic terms, resilience has to do with the capacity of the farm business to survive various risks and other shocks. A whole-farm stochastic simulation model over a six-year planning horizon was used to analyse organic and conventional cropping systems using a model of a representative farm in Eastern Norway. The relative economic sustainability of alternative systems under changing assumptions about future technology and price regimes was examined in terms of financial survival to the end of the planning period. The same alternatives were...

The study was based on data collected in 39 organic farms in 9 Polish regions. The mean share of grasslands was 47.3%, i.e. twice the country average (21%). These organic farms were classified according to the EU system of farm classification (MAFF, 1992). Among 5 general agricultural types (of 9 types defined in EU), the best economic results of the stud-ied farms were found in the general type 4 (special-ized in breeding grazing cattle) and the lowest in the general type 1 (specialized in field crops). The highest economic results among the farms of the basic types (9 of 17 EU-defined types) were reached in the type 43 (cattle in total) and the lowest result, in the type 14 (other field crops excluding cereals, oil and legume plants).

Economics of Hot Water Dipping
Provedor de dados: 21
Autores: P., Maxin; K., Klopp.
Hot water dipping is an appropriate method to protect apples against spoilage  caused by gloeosporium rot. Tests on the varieties Topaz and Ingrid Marie at the  OVB Jork (Germany) have demonstrated an effective reduction of spoilage from  between 80% and 92% in charges by an infection rate of 40%. The result of an  intensive R&amp;D process between 2002 and 2003 is the development of a praxis-tested  big box (300 kg) dipping station. With the first Bio Dipping systems now on the  market it has now been possible to analyse the economics of this process.  The costs of the systems per apple farm have been calculated from the fixed capital  costs for the system itself (including maintenance costs) and from the variable costs  based on an average crop of 250 t...

Organic fruit growers often suffer economic losses due to insect damages. The available natural pest control products are not always effective; and most important: many organic fruit growers would prefer not to use any pesticide at all. EcoOrchard, a CORE Organic Plus project (2015-18) aims to collect existing knowledge and generate new knowledge in order to use Functional AgroBiodiversity (FAB) successfully in orchards. This includes experimental trials in seven countries on the potential of inter-row flower strips for control of key pests and natural enemy augmentation, the establishment of the EBIO-Network as a European-wide network of stakeholders for collecting, sharing and improving  scientific and practical knowledge and experience in FAB...

Eco-Regions: How to link organic farming with territorial development
Provedor de dados: 21
Autores: Schermer, Dr. Markus; Kirchengast, Mag. Christoph.
Organic farming in Austria has seen a rapid development as all over Europe. In some alpine regions over 50% of the farms have converted to organic. Thus the idea of forming “Eco-Regions” (“Bioregionen” in German), transforming organic farming values from a farm level to a regional scale, emerged. The paper presents the results of an action research based project to develop a model for the formation of Eco-Regions and to monitor the success in cross-sectoral networking. Besides a number of prerequisites also bottlenecks for the formation become apparent. The paper describes the model and the implementation in two distinct regions.

Autores: Huusela-Veistola, Erja; Alanen, Eeva-Liisa; Hyvönen, Terho; Kuussaari, Mikko.
Short-term rotational fallows, new set-asides and seed mixtures containing  specific seed-bearing crops are best alternative to provide seed food for farmland  birds (Hyvönen &amp; Huusela-Veistola 2011). The age of set-aside and vegetation  structure are more important than seed mixture or plant species richness in  supporting insect food for birds, and therefore set asides of various ages are  needed (Hyvönen &amp; Huusela-Veistola 2011).  Even a short-term fallow sown with a simple seed mixture can encourage  populations of generalist predators (Huusela-Veistola &amp; Hyvönen 2006), but longterm  set-asides may be even better for natural enemies (Huusela-Veistola 2008).

Farmers in coffee producing countries may not be aware of the economic, social and ecological benefits available through organic agriculture. At a local, regional and global scale, smallholder coffee farmers can discover that organic production methods are linked to provisioning, regulating, cultural and supporting ecosystem services. It is assumed that organic agriculture has a significant influence on soil parameters, and by association, on ecosystem services. Differences between farming systems in soil chemical properties reveal advantages for coffee farmers and shows the ecosystem services derived through organic agriculture at a local level.  Benefits discovered in organic coffee systems are higher inputs of organic matter, higher biodiversity of soil...

On the Hessian state domain Frankenhausen near Kassel the project “The Integration of Nature Conservation into Organic Farming” (supported by the German Federal Agency for Nature Conservation with funds of the Federal Environmental Ministry) aims to support biodiversity not only by restoring biotopes on the farmland. The focus lies on measures to enhance the diversity on the arable land and the pastures of the farm. A participatory approach is striven for, in which the scientists and planners take the role of a companion catalyst or moderator.

Accelerated compost (AC) is a newly developed commercial compost from market organic wastes and animal manure with composting accelerated within twenty one (21) days using a specific microorganism. However, information on effect of AC on soil properties is scarce. Therefore the field experiment was conducted in Ibadan to assess the effect of an AC on the properties of an Alfisol using maize (Zea mays L.) as a test crop. The experiment was laid out in a randomized complete block design with three replications.

Effect of additional heating, floor length, straw quantity and piglet nest accessibility on piglet losses in organic farrowing pens
Provedor de dados: 21
Autores: Vermeer, Herman; Houwers, Wim.
Newborn piglets on organic pig farms have a lower chance to survive their first week than conventional piglets. Poorer climatic conditions, a loose housed mother, large litters with low birth weights are some of the causes. In a series of experiments the effect of housing and climate measures were investigated. Additional floor heating around farrowing to increase vitality did not reduce piglet mortality. Enlargement of the solid floor to facilitate maternal behaviour also didn’t show a lower mortality. In the third experiment the amount of straw didn’t give a lower mortality, but longer flaps in the opening of the piglet nest tended to reduce mortality.

Effect of age and cutting frequency on below-ground biomass in grass-clover
Provedor de dados: 21
Autores: Vinther, F.P.
Significant amounts of plant biomass and fixed N are incorporated into soil as roots, nodules and root exudates during the growth of grass-clover, which consequently is exposed to soil microbial degradation when the field is ploughed. This has major implications for our understanding of the potential contributions of legumes in the N economics and losses in grass-clover cropping systems.     We have studied the effects of grass-clover pasture age and cutting frequency (simulated grazing) on the development of the above ground as well as the below ground plant biomass, with emphasis on below-harvest contribution to the total N2 fixation.

Effect of agronomic management practices on lettuce quality
Provedor de dados: 21
Autores: Rattler, Sabine; Briviba, Karlis; Birzele, Barbara; Koepke, Ulrich.
The effect of different agronomic strategies on the nutritional quality of head lettuce was investigated. The factors included were irrigation type, fertiliser input type and level. The assessed ingredient parameters were nitrate, lutein, ß-carotene and polyphenols. Hygiene was described by total aerobic bacterial count and number of coliform bacteria, Escherichia coli, Salmonella enteritidis, Enterococcus and Enterobacteriaceae. Lettuce treated with mineral nitrogen fertiliser (calcium ammonium nitrate) displayed a higher nitrate content than lettuce treated with organic manures (fresh farmyard manure (FYM), rotten FYM (fermented nettle extract). Nitrate concentration in lettuce tended to increase with increasing amounts of fertiliser, independent of...

Effect of alternative seed treatments on seed-borne fungal diseases in tomato
Provedor de dados: 21
Autores: Kasselaki, A. M.; Malathrakis, N. E.; Goumas, D. E.; Leifert, C.
The fungus Didymella lycopersici infects tomato seed and results in great losses before and after germination. To control the disease, seed companies use thiram preventively, although human allergy problems have been reported. For this reason as well as to address needs in organic agriculture, this study has focused on the effects of alternative methods of control. Nitrite solutions and resistance inducers were tested in a growth chamber. Results showed that soaking the seed in a nitrite solution with a concentration of 300mΜ (in citric acid buffer, pH 2) for 10 minutes reduced losses due to low seed germination and disease incidence in the germinated seedlings completely. When applied for longer intervals sodium nitrite proved phytotoxic whereas in...

EFFECT OF AN IN-SEASON LIVING MULCH ON LEACHING OF INORGANIC NITROGEN IN CAULIFLOWER (BRASSICA OLERACEA L. VAR. BOTRYTIS) CROPPING IN SLOVENIA, GERMANY AND DENMARK
Provedor de dados: 21
Autores: Kristensen, Hanne Lakkenborg; Campanelli, G.; Bavec, Franc; von Fragstein und Niemsdorff, Peter; Canali, S.; Tittarelli, F.
Vegetables with a high nitrogen demand such as cauliflower may cause intensive leaching of nitrate to the environment in conventional as well as in organic production. In organic cropping systems, the use of an in-season living mulch may decrease the risk of nitrate leaching after harvest when left growing in the field to the end of the leaching season in spring. The aim of this study was to investigate the effect of growing an in-season living mulch including legumes on the risk of leaching of inorganic nitrogen over winter, and soil nitrogen availability the following spring. Three field experiments were carried out in Slovenia, Germany and Denmark in the frame of the Interveg project (CORE organic II). Evaluation of soil inorganic nitrogen content was...

Effect of annual self-reseeding legumes on subsequent crops in organic rotation programme
Provedor de dados: 21
Autores: Al-Bitar, Lina.
Soil fertility management is a critical issue in organic agriculture, and nitrogen supply is the most important aspect, especially in the Mediterranean region. Biological nitrogen fixation by legumes seems to be a successful strategy in that nitrogen-fixing legumes can provide most of the nitrogen used in Mediterranean agriculture in a form not readily leached. According to Pimentel et al., 1992, in the U.S., an estimated $50 billion worth of nitrogen is provided by biological N fixation. Thus, the inputs of nitrogen into Mediterranean agricultural systems by biological fixation in nodulated legumes are fundamental to obtain sustainable and economic production.  This study aimed at evaluating the impact of annual self-reseeding legumes on subsequent crops...

Effect of arbuscular mycorrhiza fungi on growth and development of onion and wild relatives
Provedor de dados: 21
Autores: Scholten, Dr. Olga E.; Galvan-Vivero, Guillermo; Burger-Meijer, Karin; Baar, Dr. Jacqueline; Kik, Dr. Chris.
Arbuscular mycorrhizal fungi play an important role in the uptake of nutrients and water from soil. Onions, Allium cepa L., are plants with a shallow root system. As a result, onion plants need a lot of fertiziler for their growth. Furthermore, onion plants are sensitive to drought. The aim of the current research project is to study the beneficial effect of mycorrhizal fungi on the growth and development of Allium species and to determine whether it is possible to improve onions for mycorrhizal responsiveness by means of breeding.

Effect of ascorbic acid and glutathione on the production of nitriles by myrosinase
Provedor de dados: 21
Autores: Bellostas, Natalia; Sorensen, Jens Christian; Sorensen, Hilmer.
Biofumigation is based on the use of glucosinolate-containing plants for the control of soil-borne pest and diseases. Upon tissue damage, glucosinolates are hydrolyzed by endogenous enzymes (myrosinase) and a range of biologically active compounds are formed. Isothiocyanates (ITCs) are the quantitatively dominating products formed at neutral pH. Most of these compounds are volatile and only sparingly soluble in aqueous systems, and depending on the R-group structure and the presence of nucleophiles, further transformation of ITCs occurs. At lower pH and in the presence of certain molecules able to deliver two redox equivalents, the proportion of nitriles increases at the expense of ITC.   The effect of ascorbic acid and glutathione on the production of...

Effect of barley preservation method on milk production and milk quality in organic farming
Provedor de dados: 21
Autores: Adler, Steffen A.; Randby, Åshild T.
The effect of dried vs. ensiled barley (cv. Arve) on feed intake, milk yield and quality in organic production was tested in two experiments in Northern Norway.   In the first experiment, two groups were given either 40% or 10% concentrated feed (barley) per cow and year, calculated on energy basis. Grass silage was fed ad. lib. Both drying and ensiling preserved barley properly and resulted in approximately the same feed intake and milk production. Cows in the group with 10% barley had lower milk protein concentration than cows in the group with 40% barley. The palatability of barley was in general low, and several cows refused parts of their allowances throughout the experiment.  The second experiment had a cross over design with three treatments.

Effect of Barley-Legume Intercrop and Major Nutrients on Disease Frequency in an Organic Farming System
Provedor de dados: 21
Autores: Kinane, Dr. J.; Lyngkjær, Dr. M.
The effect of barley-legume intercrop in an organic farming system on disease incidence was investigated over two years. Two barley varieties were intercropped with lupin, faba bean or pea. Several diseases were observed: ascochyta blight (Mycosphaerella pinodes) on pea, brown leaf spot on lupin and chocolate spot (Botrytis) on bean. On barley net blotch (Pyrenophora teres), brown rust (Puccinia hordei) and powdery mildew (Blumeria graminis f. sp. hordei) (in order of incidence) were detected. A general reduction in disease was observed in all intercrop systems compared to the corresponding monocrop, but the reduction was only statistically significant in the cases of brown leaf spot on lupin, ascochyta blight on pea and net blotch on barley.

The effect of barley-legume intercrop in an organic farming system on disease incidence was investigated. The legumes were lupin (‘Prima’), faba bean (‘Columbo’) and pea (‘Bohatyr’ and ‘Agadir’). The barley variety was ’Otira’. Diseases were detected on pea and barley. On pea, only Ascochyta blight was observed. When either pea variety was intercropped with barley, the level of Ascochyta was reduced. Net blotch (Pyrenophora teres), brown rust (Puccinia recondita) and powdery mildew (Blumeria graminis f. sp. hordei) (in order of incidence) were monitored on barley between flag leaf emergence and heading. The levels of all three diseases were reduced in every intercrop treatment compared to the barley monocrop. However, this reduction was only statistically...

Effect of calcified seaweed application on grazing preference by dairy cows
Provedor de dados: 21
Autores: Younie, David; Blanke, Bettina.
This report was presented at the UK Organic Research 2002 Conference. An experiment was carried out to determine whether the application of calcified seaweed improved the preference of organic dairy cows for pasture. Two treatments were applied in May 2001; calcified seaweed applied at 625kg/ha (C+) or no application (C-). The number of cows grazing within individual plots was recorded in July and August 2001. A significantly higher number of cows were recorded in C+ plots than in C- plots. This effect could not be explained by changes in soil or herbage analysis. There may have been additional unknown effects of the C+ treatment on herbage palatability but the results may also have been influenced by external factors such as the location of water troughs.

Effect of clover management (Rhizobium seed inoculation and greenwaste compost amendments) and variety choice on yield and baking quality of organic spring and winter wheat
Provedor de dados: 21
Autores: Wilkinson, A.; Young, D.; Lueck, L.; Cooper, J. M.; Wilkockson, S; Leifert, C.
Yield and protein content of wheat produced under organic standards was repeatedly shown to be between 20 and 40% lower than levels achieved in conventional farming systems. This is thought to be at least partially due to insufficient N-supply to the crop later in the growing season and poor adaptation of the currently used wheat varieties to organic production conditions. To address these problems, a factorial field trial was established to study the effect of Rhizobium inoculation of clover seeds and application of compost amendments to clover swards grown prior to different varieties of wheat. Three winter wheat and four spring wheat varieties were chosen from a range of European breeding programmes. Results showed that variety choice had the greatest...

Autores: Steinshamn, Håvard; Thuen, Erling; Brenøe, Ulrik Tutein.
The effect of clover species and level of concentrate supplementation on milk fatty acid (FA) composition has been studied. White (WC) and red clover (RC) grown in mixture with grasses were preserved in round bales and fed to autumn calving dairy cows during the first 10 weeks of lactation. Milk FA was higher in linolenic acid, vaccenic acid and rumenic acid for RC than for WC silage (0.90 vs. 0.79 %, 1.52 vs. 1.36 %, 0.90 vs. 0.75 % for these 3 FA, re-spectively), and RC silage gave a higher n-3/n-6 milk FA ratio than WC (0.98 vs. 0.72). Concentrate sup-plementation decreased the level of vaccenic acid (1.21 vs. 1.68 %), linolenic acid (0.63 vs. 1.05 %) and the n-3/n-6 ratio (0.55 vs. 1.16) as compared with no supplementation, and the effect of...

Effect of Compost versus Animal Manure Fertilization on Crop Development, Yield and Nitrogen Residue in the Organic Cultivation of Potatoes
Provedor de dados: 21
Autores: Willekens, Koen; De Vliegher, Alex; Vandecasteele, Bart; Carlier, Lucien.
Organic farmers in Flanders use manure from extensive conventional livestock systems due to a lack of animal manure from organic producers. The research question was if on-farm prepared compost mainly consisting of vegetal residues can be a good alternative. A long-term fertilization trial with a 4-year crop rotation of maize - potatoes - spring barley - red clover is carried out on two fields with a time difference of one year. The fertilization treatments are on-farm prepared compost, applied as a single dose and a double dose, farmyard manure, slurry and slurry combined with composted municipal waste. This paper concerns the experimental results of the potato crop in 2006 and 2007. The nitrate content of the plant juice was monitored and the potato...

EFFECT OF CONSERVATION PRACTICES ON FUNCTIONAL DIVERSITY AND ASSEMBLY OF WEED COMMUNITIES: A DATABASE OF FUNCTIONAL TRAITS
Provedor de dados: 21
Autores: Sans, F. Xavier; Armengot, Laura; Blanco-Moreno, José Manuel; Bocci, Gionata; Carlesi, Stefano; Barberi, Paolo.
The incorporation of conservation agriculture techniques (e.g. reduced tillage and green manures) in organic farming systems brings many benefits to the environment and reduces energy use (Holland, 2004). One of the main drawbacks of the use of reduced tillage is the potential increase in weed infestation and shifts in the weed community composition, sometimes to the benefit of more difficult-to-control species (Bàrberi, 2002; Peigné et al., 2007; Sans et al., 2011). However, weeds have an important role in maintaining farmland functional biodiversity (Bàrberi et al, 2010; Caballero et al., 2010), and this should be balanced with their potential negative impact on crop yield and quality.  Within the frame of the European project “Reduced tillage and green...

Soil organic carbon (SOC) concentration is an indicator for assessing soil quality. SOC concentration can be increased by using appropriate crop and soil management which can  increase organic matter input into soil and decrease its mineralization rate (Follett, 2001). The aim of this study was to investigate SOC content and dynamics in four inorganic and two organic cropping systems in five crop rotation. Data presented in this paper covers the first rotation from  years 2008 to 2012.

The effect of including 1,236 cows in the current reference population of Swiss Brown Swiss cattle on the accuracy of genomic breeding values was studied. The accuracy of genomic predictions based on reference populations consisting of bulls only and bulls and cows was compared. The gain in accuracy was very small or not existing at all. Reasons could be that the number of cows was too small for a reference population consisting of 4,085 bulls and that the cows and bulls were too closely related. Nevertheless, genotyping cows and subsequent inclusion in the reference population should be accelerated.

Effect of crop management practices on the sustainability and environmental impact of organic and low input food production systems
Provedor de dados: 21
Autores: Thorup-Kristensen, K.
While organic farming can reduce many of the environmental problems caused by agriculture, organic farming also includes some practices which are questionable in terms of environmental effects. Organic farming practices (rotations, fertilisation regimes, cover crop use) can differ significantly and this leads to large differences in its environmental effects. This leaves considerable scope to improve the environmental effects of organic farming. The environmental aspects of organic farming are discussed, and model simulations are used to illustrate how even moderate changes in organic rotations can have large effects on sustainability, here measured by a simple index of nitrogen lost by leaching relative to nitrogen harvested by the crops.

Provedor de dados: 21
Autores: Zarina, Livija; Zarina, Liga.
The nutrient balance in different crop rotations under organic cropping system has been investigated in Latvia at the Institute of Agricultural Resources and Economics since 2006. Latvia is located in a humid and moderate climatic region where the rainfall exceeds evaporation (soil moisture coefficient &gt; 1) and the soil moisture regime is characteristic with percolation. The average annual precipitation is 670-850 mm. The average temperature varies from -6.7 ◦ C in January to 16.5 ◦ C in July. The growing season is 175 - 185 days. The most widespread are podzolic soils and mainly they are present in agricultural fields in all regions of Latvia. In a wider sense the goal of the soil management in organic farming is a creation of the biologically active...

Effect of cultivar and soil characteristics on nutritional value in organic and conventional wheat
Provedor de dados: 21
Autores: Murphy, Dr. Kevin; Hoagland, Dr. Lori; Reeves, Dr. Philip; Jones, Dr. Stephen.
Evidence of greater nutritional value in organic crops is currently a subject of intense debate. Our objectives in this study were to test for grain mineral concentration in 35 winter wheat cultivars in paired organic and conventional systems, and to determine the influence of cultivar, soil characteristics and farming system on mineral concentration.  Here we report preliminary results that show that the grain mineral concentration in organic wheat was higher for copper (Cu), magnesium (Mg), manganese (Mn), phosphorus (P) and zinc (Zn) and lower in calcium (Ca), than the grain mineral concentration in conventional wheat. No difference was found between systems for iron (Fe) concentration.  Cultivar was significant in determining mineral concentration for...

EFFECT OF DIFFERENT ECOLOGICAL ENVIRONMENTS ON ORGANIC CULTIVATED SOYBEAN (Glycine max (L.) Merril.)
Provedor de dados: 21
Autores: Borbélyné Hunyadi, Éva.
In recent years different protein sources have gained importance. Crop cultivation plays an important role in meeting the demand for many of these. In order to improve the quantity and the quality of yields; we must acquire a complex ecological attitude and exercise a more rational use of natural resources. To succeed requires favourable material, technical and social circumstances. The exploitation of genetic capability – as a form of renewable resource – is a fundamental method for increasing yields. To do this we must harmonize the biological needs of the given variety, its ecological attributes, with the circumstances of its cultivation.   Today, the soybean is one of the most important plant sources of protein and vegetable fats (Bódis and...

Effect of different organic substrates on reproductive biology, growth and offtake of the African night crawler earthworm (Eudrilus eugeniae)
Provedor de dados: 21
Autores: Kabi, Fred; Kayima, Denis; Kigozi, Abasi; Mpingirika, Eric Zadok; Kayiwa, Ronald; Okello, Dorothy.
Rapid growth and high fecundity of E. eugeniae makes it a commercial vermicomposting agent. The worm is also a rich protein source (50-70%CP) in livestock diets. The major question, however, is how do we promote earthworm production as a strategy for ecological livestock intensification and integration with crops through earthworm domestication as a source of protein and vermicompost. Reproduction characteristics, growth and offtake of E. eugeniae were studied using four organic substrates including abattoir waste (AW), cattle manure (CM), soya bean crop residue (SBCR) and a mixture of cattle manure and soya bean crop residue (CM+SBCR) aged for 15 days. Irrespective of the substrate, length and biomass of earthworms increased at a decreasing rate between...

Effect of disinfectants on viability of Ascaris suum and  Ascaridia galli eggs
Provedor de dados: 21
Autores: Gautam, Susmita; Petkeviciute, Egle; Takeuchi-Storm, Nao; Thapa, Sundar; Mejer, Helena.
Ascaris suum and Ascaridia galli, the large round worm of pigs and poultry, respectively, persist even in intensive management systems, where a high level of hygiene is practiced. It is necessary to control these helminths to minimize production losses and improve animal welfare. Commercial disinfectants are commonly used to clean pens in conventional pig and poultry farms but their efficacy against the thick-shelled nematode eggs has not been sufficiently documented. However, it might be difficult to control these parasites because of their complex thick-shelled eggs, which can resist harsh environmental conditions. Commonly used disinfectants such as Virkon S®, FL-des GA® typically claim efficacy against viruses, bacteria and some fungi, but very few...

The impact of crop rotation, nutrient levels and use of catch crops on effect of E. repens on a sandy soil at Jyndevad on yield of winter wheat (2006), spring barley (2007-2008) and faba bean (2006-2008) was studied in an existing organic crop rotation experiment (Olesen et al., 2000; Rasmussen et al., 2006). Some of the objectives were to determine the yield loss at different levels of infestation of the weed, and to determine whether this relationship was influenced by the treatments.  For all crops, the treatments had a high impact on the yield. The two treatments that had no manure applied for up to 12 years consistently had the lowest yields. In spring barley, the two treatments with manure and with catch crops consistently had the highest yields. In...

Autores: Dvorak, Petr; Hamouz, Karel; Kuchtová, Perla; Tomasek, Jaroslav.
The aim of this experiment was to evaluate influence of mulching on the tuber yield and on the number of ware potatoes. In organic farming grass mulch for potatoes was used in 2008. For the experiments different ways of mulching (grass mulch after planting, grass mulch after second hoeing) were used and compared with bare soil (control variant). The results showed that grass mulching had positive effect on the yield of ware potatoes and some of the yield-forming components. The yield of ware potatoes was significantly higher by 9.3 t/ha in comparison with control variant. The highest number of ware potatoes was found out in the variant with grass mulch after planting.

Mulching of GM herbage can increase cereal yields compared to its removal. However, the same GM herbage removed for biogas production will provide biogas residue that can be used as spring fertilizer to cereals. This will improve N-recovery and reduce the risk for N pollution. Cooperation with existing biogas plants will be more efficient, as building small biogas plants are costly and challenging.

Effect of green manure rotation, biol and cultivar on the production of organic spinach (Spinacea oleracea)
Provedor de dados: 21
Autores: Siura, Saray; Davila, Susana.
Two cultivars (Open Pollination OP and hybrid) were evaluated in a rotation with green manure (Crotalaria juncea) and four biol concentrations (0, 20, 40 and 100%) on organic spinach crop. A statistical complete randomized block under factorial design was used. The yield was highly statically significant for the rotation with green manure (24.3 t/ha), biol (25.8 t/ha) and the interaction of rotation x cultivar (25.2 t/ha), where the production of the OP was superior to hybrid, when green manure was used. High yields obtained when green manure in rotation and high biol concentrations were used,  justifies its wide and common use, especially with small farmers, improving the spinach organic production efficiency even when an OP cultivar was used.

Provedor de dados: 21
Autores: Sangakkara, U. R.; Pietsch, G.; Gollner, M.; Freyer, B.
A field study evaluated the impact of mulching or incorporating two organic materials with differing C:N ratios on selected soil properties and the productivity of organically grown mungbean in a dry season, under rainfed conditions. While the organic matter improved the soil parameters and hence yields, incorporation had a greater beneficial impact on measured parameters, except weed numbers, which were reduced significantly by mulching with straw. Gliricidia leaves, with a lower C:N ratio than rice straw, had the better effect on soil properties and crop growth. The potential for using commonly available organic materials in smallholder tropical cropping systems to enhance productivity in dry seasons is discussed.

Effect of mechanical soil treatment in blueberry orchards
Provedor de dados: 21
Autores: Benduhn, Bastian; Maxin, Peter; Pfeiffer, Barbara.
From June 2004 onwards a trial was conducted on a blueberry farm in the Lüneburg  Heath, Northern Germany, in which methods of mechanical soil cultivation were compared  with mulching. The aim was to determine how far the mechanical methods and equipment  established for soil management in viniculture and pomiculture can be adapted to  blueberry cultivation, and can be improved. The results showed a clear advantage of the  methods based on mulch technology in the shape of increased yields. Whilst the  mechanical treatments provided acceptable weed control, they cannot be recommended  for routine use at present because of strong yield reductions associated with damage to  the shallow root system of highbush blueberry shrubs.

EFFECT OF Melia azedarach ON APHID (Brevcorinae brassicae) OF ORGANIC CABBAGE FARMING
Provedor de dados: 21
Autores: Rana Bhat, Basanta; Yubak, Dhoj GC.
In order to assess the effectiveness of botanical plant material use in reducing cabbage aphid population (Brevicoryne brassicae), an experiment was conducted in the research command area of Ecological Service Centre at Devghat-9, Gaight, Tanahun during the winter of 2001/2002. Two levels of concentration, 1:5 and 1:10, from the fresh green leaves of Bakaino (Melia azedarach L.), were applied to the aphid population in cabbage at five and ten days intervals. The result indicated that the 1:5 concentrated solution of Bakaino (Melia azedarach L.) extract at five day intervals was most effective in lowering the aphid population and scale of leaf damage as compared to other treatments. Even the 1:10 concentration sprayed at the shorter period of interval was...

Effect of mowing a legume fertility-building crop on shoot numbers of creeping thistle (Cirsium arvense (L.) Scop.)
Provedor de dados: 21
Autores: Cormack, William F.
This report was presented at the UK Organic Research 2002 Conference. Perennial weeds with spreading root systems, e.g. Cirsium arvense, are difficult to control in organic arable rotations, particularly in those without grazed leys. Competitive crops and repeated mowing are proven methods of control that can be applied to the legume fertility-building crops in stockless rotations. An experiment at ADAS Terrington in 2000 compared a standard treatment of mowing at 45 cm legume height (x4) with mowing every two weeks (x8), and mowing when thistle flower buds were visible (x3). Thistle shoot numbers counted in July 2001 were around 75% less than at start of mowing in April 2000 (mean of 9.5 shoots per m2). The results suggest that achieving and maintaining a...

Beneficial migroorganisms such as arbuscular mycorrhizal fungi (AMF) and plant growth promoting rhizobacteria (PGPR) can ameliorate plant nutrition through an extended extra-radical hyphal network and by nutrient mobilisation. In the past, host specificity may not have been adequately considered when microbial inoculants were developed for different crops. In the Bio-fertilizer Network oft he Indo-Swiss Collaboration in Biotechnology (ISCB), AMF and PGPR are integrated as bio-inoculants in wheat-rice and wheat-black gram systems.

Effect of organic crop rotations on long-term development of the weed seedbank
Provedor de dados: 21
Autores: Younie, David; Taylor, Dick; Coutts, Michael; Matheson, Stella; Wright, G; Squire, Geoff.
Changes in the weed seedbank were monitored between 1991 and 1998 in two experiments that were established to compare organic crop rotations at two sites in NE Scotland. Two rotations, replicated twice at each site, were compared and all courses of both rotations were present every year. There were relatively minor changes in weed species diversity over time, but major changes in seedbank abundance. Weed seed numbers were relatively low in rotations with a high proportion of grass/clover ley. Differences in level of seedbank across the rotation were relatively predictable at Tulloch but much less so at Woodside where factors such as the effect of the grass/clover ley seemed to play a lesser role. Other factors, such as weather and its influence on the...

Autores: Lauridsen, Charlotte; Halekoh, Ulrich; Jacobsen, M.; Jørgensen, Henry.
Most studies reported in the literature on organic versus conventional production systems and  health impact suffer  from the fact that only one replication per food produce was used, whereby the variation due to other sources could  not be estimated. The overall objective of the present studies was to study the effects of foods - based on well-defined and well-controlled food produce systems - on health and well-being after long-term consumption using the rat as a model.

Autores: Lueck, L.; Schmidt, C.S.; Cooper, J.M.; Shotton, P.N.; Hajslova, J.; Schulzova, V.; Leifert, C.
The Nafferton factorial systems comparison (NFSC) experiments facilitate the investigation of effects of, and interaction between, three production system components - a) rotational position, b) fertility and c) crop protection management - in organic, conventional and low-input crop management systems. This paper presents first results on pesticide and growth regulator residues observed over a period of two years. Residues were only detected for three (Chlormequat, Chlorothalonil and Aldicarb) of the 28 pesticides used in the experiments. As expected, residue levels were affected by the crop protection practices, but significant effects of fertility management practices were also detected. This indicates that the human health risks associated with...

Provedor de dados: 21
Autores: Cooper, J. M.; Schmidt, C. S.; Lueck, L.; Shotton, P. N.; Turnbull, C.; Leifert, C.
The effect of organic, low-input and conventional management practices on barley yield and disease incidence was assessed in field trials over two years. Conventional fertility management (based on mineral fertiliser applications) and conventional crop protection (based on chemosynthetic pesticides) significantly increased the yield of winter barley as compared to organic fertility and crop protection regimes. Severity of leaf blotch (Rhynchosporium secalis) was highest under organic fertility and crop protection management and was correlated inversely with yield. For mildew (Erysiphe graminis), an interaction between fertility management and crop protection was detected. Conventional crop protection reduced severity of the disease, only under conventional...

Milk samples from sixteen Norwegian Red dairy cows grazing mixed swards of either grass-red clover (GR) or mixed swards of sown and unsown species of grass, clover and other herbs (GCH) were collected during four periods. Both pastures were organically managed. Pasture botanical composition had no effect on milk fat, protein or vitamin concentration and only minor effects on fatty acid composition. Milk from GR had higher concentrations of the phytoestrogens equol, genistein and biochanin A than the milk from GCH. Concentrations of equol in milk from GR were higher than concentrations reported from experiments with red clover silage. The oxidative stability of the milk lipids was not affected by pasture type.

In the recent years the fruit organic production has been one the most growing sectors in food industry. Strawberries are a nonclimateric fruits, susceptible to mechanical injury and they are also highly perishable, especially the organic one. Therefore, there is a need to improve the processing of these fruits in order to obtain a semi-dried or osmodehydrated products with higher shelf-life.  The aim of this work was to evaluate the effect of PEF pre-treatment on mass transfer phenomena, water distribution and some physico-chemical parameters of strawberries subjected to osmotic dehydration. For the experiment the organic strawberries were purchased in a local market and stored at 4 ± 1 °C before analysing further processing. The fruits were washed and...

Effect of permanent ground cover on agronomic properties and soil fertility in an organic peach orchard
Provedor de dados: 21
Autores: Parveaud, Claude-Eric; Gomez, Christelle; Bussi, Claude; Capowiez, Yvan.
In conventional orchards, weeds on the raw are mainly controlled with chemical herbicides because of  their efficiency, their low cost and ease of use. The most common method in organic orchard to  eliminate weeds on the raw consists of tillage operations. However, some drawbacks of these  mechanical methods have been demonstrated: (1) the energetic cost (non-renewable energy) is high,  (2) this method is time-consuming, (3) tillage interferes with the development of superficial roots and  can hurt the trunk, (4) the physical, chemical and biological properties of the soil can be disturb and (5)  erosion and runoff potentially increase. Cover crops are interesting alternatives to manage ground  cover but the effect on the agronomic properties and the soil...

Effect of persistent subsoil compaction on N2O emissions from arable soils
Provedor de dados: 21
Autores: Regina, Kristiina; Simojoki, Asko; Alakukku, Laura; Silvennoinen, Hanna; Dörsch, Peter; Keller, Thomas.
Compaction occasionally increased N2O in soil air.  No large differences in soil air composition, N2O emissions or moisture content were found between the treatments.  The N2O concentrations at 15, 30, 50 and 70 cm depths correlated positively with the emission of N2O from the soil in both fields (r=0.4-0.7***).  The subsoil O2 concentrations correlated negatively with N2O emission, but only at the Finnish site.  The results suggest that subsoil compaction does not significantly increase N2O emissions from these soils 15-30 years after compaction. This may indicate a minor role of subsoil in the production of N2O compared with topsoil.

Autores: Birech, Rhoda; Freyer, Bernhard.
Intensive agricultural technologies introduced in Africa some six decades ago paved the way for extensive land clearing and destruction of organic materials, development of high yielding crop varieties under monoculture and replacement of landraces. Si-multaneously, pesticides and antibiotics for use in agricultural pest and disease control were being developed and soon the face of agriculture was transformed by what was termed the Green Revolution. However, the apparent success accruing from such heavy investment was short-lived since the system would easily succumb to soil erosion, reduced soil organic matter, environmental pollution and pest and disease outbreaks. The inevitable result is the inability of land to sustain food productivity and worsening...

Effect of Poultry and Green Manure Sources on the Productivity of Popcorn (Zea mays everta L.)
Provedor de dados: 21
Autores: Luka, Grace Lamba; Odion, Ehiabhi Cyril; Maiyaki, Mustafa Mohammad.
A trial was carried out at the institute for agricultural research field Samaru during the 2013 and 2014 rainy seasons to determine the effect of poultry manure and sources of green manure on the productivity of popcorn. Treatments included four poultry manure rates (0, 2, 4 and 6 t ha-1) and green manure from two cowpea varieties (SAMPEA 6 and Kananado). Green manures were obtained by clipping the cowpea foliage at 5cm from the soil surface and incorporated in 6th week to serve as green manure. Data were collected on shoot dry weight and grain yield and significant increases were recorded. It can therefore be said that good popcorn yields can be obtained by using 2 t ha-1 of poultry manure in addition to green manure from either of the cowpea varieties.

A main reason for the rapid increase in organic food consumption is the perception that organic foods have a superior nutritional composition and/or convey health benefits. However, there is currently limited scientific knowledge about the effect of production systems on food composition. The study reported here compared fatty acid profiles and levels of fat soluble antioxidants in milk from organic and conventional production systems in 5 geographic regions in Europe (Wales, England, Denmark, Sweden and Italy). Levels of nutritionally desirable mono- and poly-unsaturated fatty acids (vaccenic acid, CLA, α-linolenic acid) and/or a range of fat soluble antioxidants were found to be significantly higher in organic milk.

Plant cellular structure could be considered a complex organized system where flows are carried out by different solutes or solvents transports systems.  Passive transports, which is based on the free energy gradients, involve symplastic, apoplastic and aquaporins transmembrane transports. During osmotic  dehydration (OD) treatment the semipermeable membranes such as plasma membrane and tonoplast, are forced to separate, due to the water losses from  the vacuoles, starting the process known as plasmolysis, characterized by the loss of the turgor pressure. In the last years, OD has been extensively studied for  the partial dehydration of fruits and vegetables in order to obtain semi-moist products; however, it presents some limitations such as the low...

Effect of Rapid or slow release nitrogen supply and cover crop/weed management on crop yield, pest incidence and fruit quality in intensive organic apple production
Provedor de dados: 21
Autores: Lindhard Pedersen, H.
Apple is the commercially most important top fruit crop grown in the European Union.   In spring 2001 one-year-old trees of the apple variety ‘Ingrid Marie’ were established in an organic production system with 3.0 m between the tree rows. Each plot consisted of three semi-plots at planting distances 0.6m (5555 trees ha-1), 0.9 m (3333 trees ha –1) and 1.2 m (2777 trees ha-1). Tree growth, soil moisture, soil-, leaf- and branch analysis, diseases, fruit production, outer and inner fruit quality were measured.  The healthiest trees with the best coloured fruits were produced on trees grown in weed. But the yield was so low that production was not economical. A high production combined with trees less infected with fruit tree canker and with a satisfactory...

Effect of reduced tillage in organic farming on soil structure measured by non-destructive X-ray computed tomography in two long-term experimental field trials
Provedor de dados: 21
Autores: de Gode, Ron; Peigne, Joséphine; Fliessbach, Andreas; Brussaard, Lijbert.
Reduction of tillage intensity by non-inversion and very superficial tillage techniques is expected to have effects on soil structure such as soil porosity and soil structure stratification. Our hypothesis was that, mainly due to earthworms’ activity, soil macroporosity increases in the superficial soil layer with non-inversion and very superficial tillage compared to ploughing whereas, the opposite would be observable in the deeper soil layers. In the framework of the FERTILCROP project (http://www.fertilcrop.net/fc-home-news.html), we compared the effects of ploughing, non-inversion tillage and very superficial tillage techniques on soil structure in soil strata and more specifically on soil macropores using non-destructive X-ray computed tomography (CT)...

Effect of repeated hoeing on growth of Cirsium arvense
Provedor de dados: 21
Autores: Graglia, Enrico; Melander, Bo; Grøndal, Henrik; Jensen, Rikke K.
Infestation with Cirsium arvense in organic cropping is an increasing problem in many parts of Europe. In the present study, repeated hoeing during the first part of the growing season is suggested as a mechanical control strategy, aiming at diminishing the regenerative capacity of C. arvense. Results showed a linear relationship between the number of hoeing passes and the aboveground biomass of C. arvense in the subsequent year. However, the strong effect on the biomass of C. arvense was not followed by an increased crop yield. A low initial density of C. arvense, which did not cause any measurable yield loss, most likely explains this

Effect of root litter quality on carbon turnover and soil microbiology in topsoil and subsoil horizons
Provedor de dados: 21
Autores: Liang, Zhi; Elsgaard, Lars; Olesen, Jørgen E.
Deployment of deep-rooted crops is suggested to contribute to climate change mitigation by stimulating soil organic carbon (SOC) storage in deep soil layers where turnover of SOC is generally slower than in topsoil. Yet, there are few systematic studies on underlying mechanisms and how to optimize SOC content through deep-rooted crops. The aims of this study were to investigate the role of root chemical composition on carbon (C) mineralization dynamics in topsoil (20 cm) and subsoil horizons (60 and 300 cm) of a cultivated sandy loam, and to test the influence of root and soluble C input on soil microbial and enzymatic activities in the different horizons. We firstly analyzed the chemical properties of root fractions from divergent plant species and...

Effect of seed treatment with milk powder and mustard flour in control of common bunt (Tilletia tritici) in wheat and stem smut (Urocystis occulta) in rye
Provedor de dados: 21
Autores: Borgen, Anders; Kristensen, Lars.
In field trials mustard flour was able to control seed borne infection by common bunt (Tilletia tritici) in wheat without decreasing the germination vigour of the treated seeds. Full control of common bunt by coating the seeds with milk powder could only be achieved at doses which reduced germination vigour of the seeds. Mustard flour can be recommended as a seed treatment in organic agriculture while a treatment based on milk powder should be developed in combination with biological control. Both milk powder and mustard flour can be used to control stem smut in rye (Urocystis occulta).

Effect of Seeding Date of Wheat and Clover Plant Interactions in Cereal Systems with an Associated Cover Crop
Provedor de dados: 21
Autores: Baresel, Jörg Peter; Köckeis, M.; Weiner, J.
The success of the establishment of living mulch systems in cereals is, among other factors, dependent on the seeding time both of the main crop and the associated crop, which may be planted together or at different seeding times. In this contribution, the results of a series of experiments are summarized, where both the absolute and the relative seeding time of winter wheat as main crop and subterranean clover as associated crop has been varied. Early seeding favored the clover, later seeding the main crop. Competition can be regulated by anticipating the seeding time of one of the components. However, an equilibrated mixed canopy could be obtained by seeding both components together.

The success of the establishment of living mulch systems in cereals depends, among other factors, on the seeding density of the main crop and the associated crop. A series of experiments with 6 seeding densities of subterranean clover and 2 seeding densities of wheat was performed in southern Germany in order to assess the role of this factor using model systems with wheat and subterranean clover. Increased  seeding densities of subterranean clover increased subterranean clover biomass, reduced wheat tiller density, but improved N supply to wheat in the stem elongation stage.

Autores: Böhm, Herwart.
The quality of potatoes in stony soils can be improved by the soil separation technique. If this technique is used in autumn in combination with integrated catch-crop growing and fertilization of stable manure or slurry a higher yield was observed, but also a lower leaching rate of nitrate over the winter period. This was tested in field trials under organic farming conditions in 1999 and 2000 on the experimental farm Lindhof of the University of Kiel. Catch crops as oil radish or yellow mustard were able to fix 60 - 70 kg Nt ha-1. Tuber yield after oil radish (36.4 t ha-1) was higher than after yellow mustard (33.0 t ha-1) and was significantly higher compared to the control (30.3 t ha-1).

Organic dairy cows in Denmark has a higher frequency of liver abscesses, which is probably due to higher starch levels in the feed rations to high yielding cows compaired to conventional cows. Following abstract is based on experiments on young bulls and demonstrates whether replacing high-starch feeds with low-starch feed, such as dried grass pellets and sugar beet pulp, can reduce the problems with liver abscessation without reducing the performance level. The low-starch feed would be relevant to organic dairy production.

Autores: Witten, Stephanie; Aulrich, Karen; Böhm, Herwart.
Grain legumes, like blue lupins, are important protein feedstuffs especially in organic farming. Their content of crude protein (CP) and essential amino acids (EAA) is of great interest. The sulfur-containing amino acids (SAA) methionine and cysteine are often limiting in common diets primarily for poultry. Therefore, we investigated, whether a sulfur fertilization of blue lupins could enhance their contents of SAA and if it has other effects regarding crop yield, CP and further EAA.  Two branched (Boregine, Probor) and two determinated (Boruta, Sonet) blue lupin varieties were cultivated at an experimental station in Northern Germany in the years 2012, 2013, and 2015. The varieties were either grown with or without S fertilization (40 kg S ha-1; MgSO4)....

The experiments were conducted in Greece in 2002 and 2003. The objective of this research was to investigate i) the effect of intercrop system on weeds and ii) if each intercrop system (oat-pea or cereal legume) is going to affect the weed control differently. The light penetration within the canopy measured during the first experiment (2002), was decreased up to 90%, due to the increase of the companion crops’ leaf area. In both years the decrease of the available light to the weeds, has led to the reduction of the weed dry matter, in comparison to the pure stands. Finally the oat-bean intercrop system gave better results than oat-peas system. As a result we can say that the intercrop system constitutes a new approach to weed control for low input...

Soil-borne diseases are one of the most important problems in organic and other ‘low input’ soil-based greenhouse production systems. While chemical soil disinfection has been the method of choice in conventional farming systems, soil steaming has been the main strategy for the control of soil borne diseases in organic production. Both methods are extremely expensive and have been increasingly restricted for environmental reasons by government and organic standard setting bodies respectively.  The use of tolerant varieties and of grafting onto resistant rootstocks were evaluated as potential replacements for soil steaming in organic and low input systems and found to be as effective in reducing root disease and increasing root fresh weight, fruit yield and...

Rainfall is the single most important factor affecting yield and biomass accumulation by crops as well as residue decomposition in the tropics. The ability to capture this resource in organic systems calls for appropriate techniques. Kenya experiences bimodal type of rainfall with two rainfall peaks; the long (730 mm) and the short (376 mm) rains. Rainfall fluctuations in both seasons are becoming more common in the recent years with a likelihood of crop failure in one out of five years.

Effect of weed management strategies on the risk of enteric pathogen transfer into the food chain and lettuce quality
Provedor de dados: 21
Autores: Fischer-Arndt, M.T.; Köpke, U.
The hygienic quality of raw edible vegetables such as lettuce may be influenced by   pathogen transfer from soil to plant, which might occur during weed control by hoeing or as splash-effects during rainfall. The hygienic quality is often discussed when farmyard manures are applied during production, as e.g. in organic farming systems. In a field experiment, the effects of weed control on pathogen transfer from soil fertilised with farmyard manure to lettuce (Lactuca sativa, var. capitata) were evaluated. First results do not confirm pathogen transfer by mechanical weeding or splash effects during rainfall.

Autores: Seal, A; Bera, R; Datta, A; Saha, S; Chatterjee, AK; Barik, AK.
Organic farming has been identified as the road map for food sovereignty, economic security, and alleviation of food toxicity. And, with changing climatic patterns it has become more of a necessity for harnessing both mitigation and adaptation potentials. For sustainable agriculture qualitative developments of soil has been prioritized. But it has been a time taking process, moreover; component wise redressal has not provided much relief considering that still now not even 1% of total agricultural production world over is organic. To reach the objective in a time bound manner, besides healthy soil, healthy plant system has become pre-requisite, as also supported by ‘Trophobiosis theory’ of French scientist F. Chabassou (1985) that depicts ‘Healthy Plants’...

Eating quality of pork is to a high degree influenced by the intramuscular fat (IMF) content.  In previous studies under standardized conditions the feeding strategy was identified as a main source of variation for the IMF content in pork. In this study the effect of the implementation of a specific feeding strategy using a high portion of home-grown grain legumes on the IMF content of pork, was assessed under different conditions on German and Austrian farms. Results showed that IMF content ranged on a comparably high level of about 2.2 %. In contradiction to previous results under standardized conditions the factor feeding had no significant influence on the IMF. The feeding effect was overlapped by heterogeneous conditions on the different farms. IMF...

Effects of an organic and a conventional cropping system on soil fertility
Provedor de dados: 21
Autores: Boldrini, Dr Arianna; Benincasa, Dr Paolo; Gigliotti, Prof Giovanni; Businelli, Prof Daniela; Guiducci, Prof Marcello.
An experiment was started in 1998 in Central Italy to evaluate changes in soil fertility and the risk of N loss in an organic (ORG) and a conventional low input (CONV) cropping system. At the end of a 6-year rotation, ORG caused a higher plant biomass incorporation into the soil and thus a higher soil soluble organic carbon. The N surplus in ORG was 32% higher than in CONV, while no differences were recorded on N content in the top soil, so that ORG implicated a higher N loss from that soil layer. In ORG we recorded a higher phosphatase activity but a lower available soil P (due to application of rock phosphate in sub-alkaline soil) and a lower exchangeable K.

Effects of anaerobic digestion of organic manures on N turnover and N utilization
Provedor de dados: 21
Autores: Sørensen, Peter; Khan, A R; Møller, Henrik B.; Thomsen, Ingrid Kaag.
Animal manures and plant-based manures are used for biogas production by anaerobic digestion (AD). After AD the concentration of ammonium-N in manure is increased and the concentration of decomposable C is decreased. Thus, the potential first year fertilizer value of the manure can be increased by the treatment. However, pH is also increased by AD thereby increasing the risk of ammonia losses. The objective of this paper was to compare N turnover in soil after application of digested and corresponding undigested manures, and to compare N fertilizer values of digested manures after direct injection or surface-banding in cereals.   After AD of pig and cattle slurry the increase in potential plant availability was equivalent to 10-25% of total manure N. AD of...

Effects of applying anaerobically digested slurry on soil available organic C and microbiota
Provedor de dados: 21
Autores: Johansen, A.; Pommeresche, R.; Riley, H.; Løes, A.-K.
Anaerobic digestion of animal slurries and plant residues is a valuable technology to produce bioenergy and fertilizers in organic farming systems, while at the same time reducing propagules of weeds and parasites in the input material. However, the digestion changes the quality of the slurry by reducing its content of organic matter and increasing mineral nitrogen (N) levels. This may have profound impact on soil fauna and microorganisms as well as the biogeochemical processes they drive. Organic farmers fear that application of digested materials may have negative implications for soil fertility by reducing the input of organic matter to the soil, compared to fertilizing with traditional animal slurries or green manures. Hence, it is important to gain...

In recent years, biological fertilizers have received special attention in sustainable agriculture. Inoculation with arbuscular mycorrhizal fungi and free-living nitrogen-fixing bacteria had significant effects on corn photosynthesis and yield; the highest photosynthesis rate and yield were obtained with dual inoculation with fungus plus bacteria. These outcomes were also affected by cropping systems, but to a lesser extent. Therefore in organic and low input cropping systems, a combination of mycorrhiza and free-living bacteria performed satisfactorily.

Manures and crop residues can be utilised for digestion, without any significant losses of nutrients. This paper presents the results of field trials about the effects of biogas digestion in a mixed organic cropping systems on nutrient cycling and yield of a whole crop rotation. Digestion of slurry affected yields and N uptake only after soil incorporation. The inclusion of crop residues for digestion increased the amounts of “mobile” manure. N uptake and yield of non-leguminous main crops increased about 10%, due to a more adapted allocation of nutrients within the whole cropping system by reallocation of N towards the crops with higher N needs. Additionally, removing the cover crops in autumn and their digestion increased the fertilizing efficiency of N,...

Autores: Leiber, Florian; Stadtlander, Timo; Wohlfahrt, Jens; Sandrock, Christoph; Maurer, Veronika.
Insect-based protein meals are in discussion as sustainable components in livestock and fish diets, with a potential to recycle wasted food materials and to replace partly feeds from arable land. Black Soldier Fly (BSF; Hermetia Illucens) is of particular interest in this context. Since insect production for animal feed appears as an additional trophic level in the food chain, it should either base on substrates, which are not directly edible for livestock and fish, or significantly improve feed efficiency or product quality to justify its application. Feed efficiency and product quality after replacing conventional protein sources by BSF meal were therefore tested in recent experiments with layers, broilers and trout. In a layer experiment, respectively...

Selenium is an essential nutrient for animals, humans and microorganisms. Se deficiency in humans has been linked  to a plethora of physiological disorders.  Increasing evidences point to an anticarcinogenic  potential of Se-compounds.    To address Se deficiency in the human diet, agronomists and plant breeders are pursuing complementary strategies to produce crops with greater Se concentrations.    Catch crops have been used successfully in agriculture, increasing nitrogen and sulfur content in the soil and avoiding nutrient leaching. In this experiment we study whether catch crops can have similar beneficial effects regarding Se.

A long-term experiment was established to examine the crop yield and the weed infestation, focussed on Canada thistle (Cirsium arvense), as effect of different intensity of primary tillage (mouldboard plough deep or shallow, double-layer plough, chisel plough) in combination with or without stubble tillage. The most effective ways to keep the infestation of C. arvense at a low level were deep mouldboard ploughing and the use of a double-layer plough. After the experiment had run seven years, the thistle biomass was &lt; 2 g DM m-2 in these treatments, compared to 23–26 g DM m-2 in the treatments with chisel ploughing or shallow ploughing. In all treatments, stubble tillage in addition to primary tillage significantly reduced the thistle biomass by 30–80 %....

Provedor de dados: 21
Autores: Tittarelli, F.; Campanelli, G.; Farina, R.; Napoli, R.; Ciaccia, C.; Testani, E.; Leteo, F.; Canali, S.
A field experiment was carried out in Central Italy on growing melon (Cucumis melo L.) after barley (Hordeum vulgare L.). Three different systems of cover crop termination (green manure, roller crimper and fallow, as control) were combined with three doses of compost (0, 15  and 30 t ha-1 d.m.) in a strip plot design. The main objective of the research was to evaluate their effects on organic melon production and on short and long term soil nitrogen (N) fertility. Marketable yield and quality and soil N availability along the melon cycle were determined and a simplified N budget calculated. Green manure (GM) treatment showed the highest total and marketable yield, followed by fallow (FA), while roller crimper (RC) was characterized by a significant lower...

The Nafferton Factorial Systems Comparison (NFSC) experiments are part of a long-term field trial that compares organic and conventional systems of crop rotation, crop protection and fertility management, in a factorial design.  Pest and disease incidence in vegetables in the 2005, 2006 and 2007 season are reported.  Cabbage root fly damage was always reduced under organic crop protection, but there were no consistent trends for the effects of fertility management on this pest.  Sclerotinia in lettuce was consistently higher under conventional fertility management.  Blight in potatoes was enhanced in the 2007 season by the combination of conventional fertility management and organic crop protection practices.  Mechanisms for these effects, including the...

Effects of culivation conditions for apples on growth rates of fruit fly larvae and contents of phenolics
Provedor de dados: 21
Autores: Pedersen, Senior scientist Hanne Lindhard; Brandt, Senior scientist Kirsten; Nørbæk, Senior scientist Rikke; Ejlersen, A.
The different cultivation treatments significantly and systematically affected both rate of development of fruit fly larvae and contents of phenolic compounds, but not the total number of flies produced. This is in accordance with the hypothesis that cultivation methods can give large enough changes in composition of plant foods to affect physiological aspects important for health of consumers.  It indicates that further stusies should be made of the links between plant cultivation, plant composition and health, for example regarding the question of the nutritional value of organic versus conventional food.

Effects of Cultivation Conditions for Apples on Growth Rates of Fruit Fly Larvae and Contents of Phenolics
Provedor de dados: 21
Autores: Brandt, Kirsten; Ejlersen, Astrid; Nørbæk, Rikke; Lindhard Petersen, Hanne.
Apples were grown with 3 different alleyway groundcover management strategies, providing a wide range of nutrient availabilities to the trees, spanning the ranges normally found in both conventional and organic orchards. These treatments had significant effects on both yields and incidence of fungal diseases. However, the differences in yields and disease incidence cancelled each other out, resulting in identical average yields of marketable fruit, as reported earlier (Lindhard Petersen &amp; Bertelsen 2002).     These results indicated that the composition of the fruit may also differ, and that this material is useful as a model for investigating how growth conditions influence the content of nutritionally relevant compounds, and thus may affect the...

Autores: Dupont, Y.; Strandberg, B.
Bees and other flower-visiting insects are experiencing periods of food shortage, particularly in intensively managed agricultural landscapes in Europe. As part of the Danish project EcoServe (http://agro.au.dk/ecoserve/) we therefore investigated whether increased richness of selected herbaceous species in organic hay fields acted as a floral resource thus enhancing abundance and biodiversity of pollinators. Moreover, we investigated if availability of floral resources was affected by cutting regime (timing and number of cuttings during the growing season) in 11 herbaceous species, which are often used in grassland seed mixtures.    In a field survey, we visited 20 organic hay meadows of different age (3-100 years), and conducted surveys regularly...

Effects of different row distances and seed densities on yield and quality of blue lupins (L. angustifolius) in organic farming
Provedor de dados: 21
Autores: Böhm, Herwart; Aulrich, Karen.
Blue lupins have become more important in animal feeding due to increasing organic animal husbandry. The high protein content of blue lupins shows the best protein quality of the home-grown grain legumes combined with low starch content. The feed quality of blue lupins can be analysed very quickly and cost-effi ciently with NIRS. Weed infestation in pure stands of blue lupin is often a problem. Mixed cropping systems are a good alternative for weed suppression, but the yield percentage of blue lupins in mixed cultivation is low.  Weed infestation can be reduced by hoeing. For this, blue lupins were cultivated in wider row distances (25.0 cm, 37.5 cm) with the possibility of hoeing, and compared with the cultivation to 12.5 cm row distance (only harrowing)....

Autores: Schori, Fredy.
In order to identify the optimum stocking rate for grazing dairy cows in organic farming, grazing experiments were conducted from 2004 to 2006. Cows of one herd were divided into two groups during vegetation periods. The paddocks of the rotational pasture were split in a way that the low stocking rate group (SRL) had 15% more pasture area than the high stocking rate group (SRH). Post grazing sward height for SRH, was decisive for the simultaneous change of the sub-paddocks. Annual stocking rates for SRH were 2.0, 2.3 and 2.3 cows per hectare (ha). In the offered herbage mass for SRL significant lower ash-, CP-, APDE- and APDN values as well as higher NDF values were detected. Sugar- and NEL values were unaffected. No significant differences were found for...

Direct drilling has been studied by MTT Agrifood Research Finland since the 1980s, but conclusions here are mainly based on field trials on clay soils in 2000s. Differences in amount and quality of yield from ploughed and no-till soil vary between years, fields and species. Timing and implementation of drilling in no-till soil is especially challenging. Oat did grow and yield more reliably than other spring cetreals when direct drilled. The protein content of spring cereal grains was low in direct drilling.

Autores: V., Paolini; F., Prevot; Ph., Dorchies; H., Hoste.
The effects of tannins on adult populations of Haemonchus contortus, Trichostrongylus colubriformis and Teladorsagia circumcincta  in goats are characterised mainly by a decrease in egg excretion without any significant changes in worm number. In contrast,  the impact of tannins on T. colubriformis or T. circumcincta third-stage larvae (L3) is associated with a significant reduction in worm  establishment. The objective of the present study was to examine the effects of quebracho extract tannins on H. contortus L3. The  consequences of consumption of sainfoin hay were also examined.

Effects of Farm Type and Different Intensities of Soil Tillage on Cash Crop Yields and Soil Organic Matter
Provedor de dados: 21
Autores: Schulz, Franz; Brock, Christopher; Leithold, Günter.
An organic long-term field experiment has been carried out at the experimental station Gladbacherhof (Giessen University, Germany) since 1998 to survey the performance of agronomical, economical and ecological indicators dependant on farm type and tillage intensity. This article presents results on cash crop yields and changes in humus contents in the first two rotations of the experiment. It can be concluded that organic stockless farming without ley affects cash crop yields and demands special attention with regard to a sustainable humus management. Stockless farming with rotational ley on the other hand up to now showed a satisfactory performance when compared to a mixed farm type with livestock. As for the yields, reduced tillage systems could cope...

Effects of green manure storage and incorporation methods on greenhouse gas fluxes and N mineralization after soil application
Provedor de dados: 21
Autores: Carter, Mette S.; Sørensen, Peter; Petersen, Søren O.; Ambus, Per.
Organic arable farming faces challenges with low crop yields, partly due to inefficient use of green manure-derived nitrogen (N). Under current farming practices, green manure leys are often cut and mulched during the growing season with the associated risk of environmental N losses, leading to eutrophication and global warming. In this 3-month incubation experiment, we tested a new green manure management strategy as part of the ICROFS project HighCrop. With the new strategy, green manure leys are instead harvested and preserved until the following spring either as compost mixed with straw (grass-clover:straw, 4:1, w:w) or as silage of harvested ley biomass. In spring, these two green manure materials can then be used for targeted fertilization of spring...

Introduction: Homeopathic treatment is a common method against bovine mastitis in organic herds. In a study conducted in a large biodyn farm in Brandenburg (D) considering 261 cases of acute or chronical mastitis, we used four different combinations of homeopathic remedies depending on clinical state of the mastitis (e.g. general findings, pain, swelling or secretion). The remedies were administrated orally. The control group was treated with antibiotics intracisternally for three days at minimum until the cow was clinically cured or defined as therapy failure. While the cure rate was calculated from clinical and laboratory data (bacterial findings and somatic cell count), the further development of the treated cows during the lactation was confirmed using...

Two seasons (2005/06 and 2006/07) of field experiments which aimed to study the suitability of new and established husked oat varieties, variety mixtures and a husked oat population for organic systems were established at two sites in the west and east of the UK. The ground cover and leaf area indices of the varieties had significant effects on final yields in the 2005/06. Mixtures generally yielded similarly to the means of component varieties but the mixtures in 2005/06 and 2006/07 had 25 % and 18 % less disease, respectively, than the average of the component varieties at one site.

Effects of inclusion of red clover silage on the carriage of gut pathogens in steers
Provedor de dados: 21
Autores: Bakewell, E. L.; Sanderson, R.; Davies, D. R.
Eight Hereford x Friesian steers prepared with rumen and duodenal cannulae were offered increasing proportions (increase of 33% each period) of red clover to grass over four periods with grass silage fed throughout to 4 steers as an experimental control. Numbers of Escherichia coli and Listeria were enumerated in silage from rumen, duodenal digesta and faecal samples at time points throughout each period. The results indicated that no silage contained E.coli whilst all silages had high populations of Listeria.  Pathogen populations were lowest in the duodenum and highest in the rumen, although large populations were also found in faeces.  The populations of E.coli were generally 10 fold lower than those of Listeria. Feeding red clover appeared to reduce...

Autores: Royer, E.; Cazaux, J.G.; Maupertuis, F.; Crepon, K.; Albar, J.
In three experimental facilities (Exp.1, 2 and 3), two organic diets, one complex including processed feedstuffs as wheat bran and heat-treated soya beans (control), the other simplified and containing over 80 % of cereal and pulses (CP), were compared for growing-finishing pigs. The base components of the CP diets were moist maize grain, wheat and faba beans in Exp.1, triticale plus coloured-flowered peas in Exp.2, and triticale, oats, white-flowered peas and faba beans in Exp.3. The diets were formulated with similar energetic values and a lysine content (0.70 g ileal digestible lysine /MJ NE) 20 % lower than the conventional mean requirement for growing pigs. However, the CP diet had a lysine proportion 30% lower than requirement in Exp.1 and did not...

Effects of intercropping and fertilization on weed abundance, diversity and resistance to invasion
Provedor de dados: 21
Autores: Sans, F. X.; Altieri, M. A.
This paper aims to evaluate the effects of the cover crop type (Vicia villosa monoculture vs. V. villosa and Hodeum vulgare polyculture) and the type of fertilization (organic vs. chemical) on the structure of the weed community (biomass, number of species, diversity and evenness) and its invasibility through the experimental introduction of Brassica sp. seeds as a target invader species. Results show that weed biomass, species richness and diversity of the weed community are significantly reduced by inter-cropping, but are not affected by the type of fertilization. In organic plots, the density increases and the complementary pattern of polyculture resource use reduces weed abundance and Brassica sp. invasion, while the rapid emergence and fast growth of...

Effects of landscape agricultural intensification and management on weed species richness in the edges of dryland cereal fields.
Provedor de dados: 21
Autores: Romero, Albert; Chamorro, Lourdes; Blanco-Moreno, José Manuel; Armengot, Laura; Jose María, Laura; Sans, Francesc Xavier.
An extensive survey of weed vegetation was conducted in the crop edges of 180 organic and conventional dryland cereal fields in nine localities of NE Iberian Peninsula to assess the effect of landscape agricultural intensification and management on weed diversity.   This preliminary results show that averaged weed species richness per edge (alpha-diversity) and floristic homogeneity among edges are higher in organic than conventional fields. Only in conventionally managed fields, elevated landscape intensification is associated to higher weed alpha-diversities and floristic homogeneity among crop edges.  The expression of high-quality weed flora is higher in organic than in conventional crop edges but, conversely, it is only sensitive to landscape...

Effects of long-term farmyard manure applications on soil organic matter, nitrogen mineralization and crop yield – a modeling study –
Provedor de dados: 21
Autores: Dux, J.; Fink, M.
To develop sustainable cropping systems we need to predict both short-term and long-term effects of management practices on soil fertility. For this purpose agro-ecosystem simulation models are valuable tools. We used the Daisy model to simulate a three-year crop rotation (beetroot, onion, white clover, potato) over a period of 40 years. With this rotation, three rates of farmyard manure were tested (0, 15, 28 t ha-1 year-1). After 40 years without manure soil organic matter carbon (SOM-C) decreased by approximately 40%, and increased by 27% with the highest application rate. SOM turnover did not reach equilibrium at the end of the experiment. Nitrogen mineralization from SOM followed in the long-term (40 years) the slowly changing time courses of SOM....

Twenty-four multiparous Holstein-Friesian dairy cows in mid lactation were used in a 33 Latin square changeover experiment with three 4-week periods to investigate the effect of altering the ratios of red clover (RC) silage and maize silage in the forage component of their diet.  Ratios (in the dry matter (DM)) were: RC10, 0.1 RC:0.9 maize; RC50, 0.5 RC:0.5 maize; RC90, 0.9 RC:0.1 maize.  All cows received ad libitum access to their allocated forage with 4 kg of a standard concentrate per day.  Whole-body N partitioning and whole-tract diet digestibility measurements were carried out using a subset of cows (n=9).  Results are presented in order of RC10, RC50 and RC90 respectively.

EFFECTS OF ORGANIC AND CONVENTIONAL N-FERTILIZATION  ON QUALITY TRAITS IN CORIANDER (CORIANDRUM SATIVUM L.)
Provedor de dados: 21
Autores: Carrubba, Alessandra; Catalano, Caterina; Militello, Marcello.
In organic cropping management of Medicinal and Aromatic Plants, the best quality expression is crucial to gain satisfactory incomes. Coriander (Coriandrum sativum L.) is an annual herbaceous plant with a commercial value due to the typical scent of its fruits (commonly termed “seeds”), rich in a pale yellow oil (1-2% in small-sized types, 0.2-0.5% in large-sized ones). Several studies have been done for determining the composition of volatile fraction of Coriander, which was found to vary also as a consequence of cropping techniques, including nitrogen fertilization. In order to gain useful information about the effects, if present at all, of organic N fertilization on Coriander quality in terms of volatiles composition pattern, a three-year trial...

Effects of organic and ‘low input’ production methods on food quality and safety
Provedor de dados: 21
Autores: Leifert, C.; Rembiałkowska, E.; Nielson, J.H.; Cooper, J.M.; Butler, G.; Lueck, L.
The intensification of agricultural production in the last century has resulted in a significant loss of biodiversity, environmental problems and associated societal costs. The use of shorter rotations or monocropping and high levels of mineral fertilisers, pesticides and crop growth regulators may also have had negative impacts on food quality and safety. To reverse the negative environmental and biodiversity impacts of agricultural intensification, a range of different ‘low input’ farming systems have been developed and are now supported by EU and government support schemes. A range of recent reviews concluded that switching to low input, integrated or organic farming practices results in significant environmental benefits and increased biodiversity in...

Effects of organic farming on weed abundance - long-term results from a site in northern Germany
Provedor de dados: 21
Autores: Verschwele, Arnd; Zwerger, Peter.
One of the aims of organic farming systems is to maintain or enhance the agricultural and natural biodiversity in agro-ecosystems. Weeds can contribute to biodiversity but also need to be controlled. Compared to conventional farming the weed density and diversity in organic farming is expected to be enhanced because of reduced fertilisation and low efficacy of control measures. It is also assumed that the diversity of crops, especially alternation of summer and winter crops, results in a greater range of weed species. However, relatively few data are available confirming this benefit of organic farming. Thus, continuous monitoring studies have been started in 1996 on a trial area for organic farming in northern Germany.

The effects of various fertilizers and different compost extracts on crop health and tomato yield were studied in the field in 2004–2005 in two locations in Iran. Treatments included different fertilizers (cattle, sheep and chicken manures, green waste and household composts and chemical fertilizers) and five aqueous extracts (from cattle manure, chicken manure, green-waste and house-hold composts and water as control). The effect of fertilizer type on tomato yield was significant in both locations (P &lt; 0.05). Organic fertilizer use did not obtain higher yields compared to using chemical fertiliser. Generally, chicken manure and green-waste compost led to the highest and lowest tomato yield among different organic fertilizers, respectively. The effect...

Pot experiment was conducted to evaluate the efficiency of different organic fertilizers on germination and early growth of tomato seedling. Four different types of compost like trichocompost, vermicompost, kitchen waste compost, cow dung based bioslurry and soil (control) were used as treatment.  Organic fertilizers except kitchen waste compost significantly influenced germination and other growth parameters of tomato seedling in comparison with control treatment. Trichocompost showed the better performance in all parameters which was followed vermicompost in most cases. The poor performance exhibited by kitchen waste compost might be due to the presence of heavy metal like lead and copper which inhibit the emergence of tomato seed and thereafter on...

Effects of organic matter input on soil microbial properties and crop yields in conventional and organic cropping systems
Provedor de dados: 21
Autores: Chirinda, Mr Ngonidzashe; Olesen, Professor Jørgen, E.
Unlike conventional cropping systems, which are characterised by targeted short-term fertility management, organic farming systems depend on long-term increase in soil fertility and promotion of soil biodiversity. This study sought to investigate long-term effects of organic matter inputs on various cropping systems in a 10-year-old experiment. Results show that in the long-term high C and N inputs enhance microbial activity. Microbial biomass N and the potential nitrification rate were higher in cropping systems based on green manure than in those reliant on inputs from animal manure and mineral fertilizer. Soil microbiological properties were affected by the individual crops in the rotation. The high microbial activity with increased organic matter...

Improper or excessive land preparation methods in vineyards before planting can have a considerable impact on  soil functionality. They include excessive levelling and deep ploughing leading to disturbances of the natural contour  of slopes and destruction, truncation and burial of soil horizons. Manipulations may significantly modify  chemical, physical, biological and hydrological balance of soils. Problems that may arise from these interventions  relate to the reduction of organic substances, enrichment of calcium carbonate and soluble salts, impacting development  and health of grapevines. Reduced water retention capacity can lead to increased water stress during  dry season, decreased water permeability and circulation of oxygen in the soil, increased...

We present the results of soil analyses after three cropping years (2002-2005). Soil organic carbon (Corg) increased over that period by 7.4% (+1.5 g Corg kg-1 soil) in the 0-10 cm soil layer in the reduced tillage plots, while it remained constant in the ploughed plots. Soil microbial carbon (Cmic) and dehydrogenase activity (DHA, TTC-reduction) were 28% higher in reduced-tillage plots in this soil layer. Biological soil quality as calculated by Cmic to Corg...

Effects of separation and anaerobic digestion of slurry on odour and ammonia Emission during Subsequent Storage and land application
Provedor de dados: 21
Autores: Hansen, Martin N.; Birkmose, Torkild S.; Mortensen, Børge; Skaaning, Kent.
A study was set up to investigate the environmental effects of anaerobic digestion and separa-tion of slurry. Volatilisation of odour and ammonia from treated and untreated slurry were compared both during storage and following land application. It was found that ammonia volatilisation was higher from uncovered stores of anaerobically digested and separated slurry than from untreated slurry, however, when slurry stores were covered efficiently, the loss rate was low and equal for treated and untreated slurry. Ammonia volatilisation following land application was found to be lower from both anaerobically digested and separated slurry compared to untreated slurry. Treatment of slurry by anaerobic digestion and separation did not reduce odour nuisances during...

Effects of shading on root and shoot development of melon (Cucubrita pepo) transplants in conventional and organic float system nurseries
Provedor de dados: 21
Autores: Bilalis, Ass. Prof. Dimitris; Kanatas, MSC Panagiotis; Konstantas, MSC Aristidis.
Float system is a common technique of tobacco and vegetables transplant production. We evaluated the shade effect on the roots and shoots development for two float systems surgeries (CV:conventional and ORG:organic) on melon transplants. The shade had differently influenced the development of the roots and shoots of the two float systems surgeries. Roots fresh weight and surface was significant higher under shade for organic transplants and significant lower under shade for conventional transplants. Hence, shoots fresh weight and surface was significant higher under shade for organic as well as conventional transplants. Because of the described differences in roots development, the transplants which were produced in the organic float system nursery had...

This paper will deal with the effects of the oral application of a probiotic preparation (Bifidobacterium animalis) and of the provision of forage (maize and grass silage) to growing-finishing pigs on the composition of the intestinal microbial population and faecal microflora as an important determining factor for pork safety. 76 pigs were reared in 4 different dietary treatments. Clinical health and immune status plus faeces samples and samples of the gut content from the duodenum, ileum, caecum and colon were collected from each animal. Since the second round of the feeding experiment was only finished in March, the datasets are still incomplete because analyses are ongoing, but preliminary results are already available. Microbial analysis showed that...

Effects of soil, root mycorrhization, organic and phosphate fertilization, in organic lettuce production
Provedor de dados: 21
Autores: Brito, L Miguel; Sampaio, Áurea; Pinto, Rui; Mourão, Isabel; Coutinho, João.
The influence of organic and phosphate fertilization, and root mycorrhization, in organic lettuce production, was assessed with factorial treatment combinations of: soil type (SOP – soil from organic and SCP – soil from conventional production) and organic fertilizer (0, 2 and 4 t ha-1) in the first trial; mycorrhizal inoculation (mycorrhized and non-mycorrhized plants) and Gafsa phosphate (0, 100 and 200 kg P2O5 ha-1) in the second. Lettuce yield decreased in the SCP with the application of increasing rates of organic fertilizer due to the very high electrical conductivity (50.1 dS m-1) and lack of maturation of this fertilizer. However, the harmful effects of the organic fertilizer were minimized in the SOP. The application of increasing rates of Gafsa...

Effects of temporarily reduced tillage in organic crop rotations on yield, earthworm biomass and development of weed pressure. First results of a case study from Schleswig-Holstein/Germany
Provedor de dados: 21
Autores: Moos, Jan Hendrik; Paulsen, Hans-Marten; Schrader, Stefan; Rahmann, Gerold.
Farming systems applying reduced tillage measures are expected to be beneficial for sustaining important soil functions (ecosystem services) and (soil)biodiversity. Furthermore a reduction in tillage intensity is connected to reduced need for energy and labour input. On the other hand waiving the plough is, especially in organic farming systems, suspected to lead to increased weed pressure and therefore decreases in yields. In this paper first results of a study on temporarily reduced tillage in organic crop-rotations are presented. Here the plough was set aside before drilling triticale at the end of four crop rotations, and expectable yields, earthworm biomass and weed pressure were investigated. First one-year-results, of the experiment on temporarily...

Effects of the period of application of K-phosphite on residues on apple fruits
Provedor de dados: 21
Autores: Kelderer, Markus; Matteazzi, Aldo; Casera, Claudio.
K-phosphite is very efficient against several plant diseases. Nevertheless at the moment there is no official  registration in Europe as a plant protection material. In conventional winegrowing K-phosphite is used in  different countries to regulate the main disease ‘Plasmopora viticola’ under the disguise of a foliar fertilizer or  a plant strengthener. In organic apple production only a few fungicides to regulate scab are available. In  addition, copper products are limited by European and national legislations. The discussion about Kphosphite  for organic farming points always at the problem of synthetic residues on the edible parts of the  vegetables. The aim of this field-trial carried out during the season of 2005 was to assess the residues on...

Autores: Eriksen, J.
The effect of S and N application on the redistribution of S and the effect of N application and time of S application (from sowing to the middle of heading) on yield and quality of spring barley (Hordeum vulgare L.) was investigated in pot experiments. Nitrogen and sulphur had a clear interactive effect on the yield of all plant parts with little or no effect of S at low N application rates and similar low effect of N without S application. About 70% of leaf N was redistributed to the ears in plants growing at adequate S supply compared with about 35% of leaf N in S-deficient plants.  The proportion of ear N and S originating from the redistribution of leaf N and S was 49% and 23%, respectively.   Deficiency symptoms were observed already at the beginning...

Autores: Di Marco, S.; Osti, F.
A two-year trial was conducted to evaluate the effects of applications of commercial formulations of the fungus Trichoderma on graftlings of grapevine (Vitis vinifera L.) in a commercial nursery where plants were grown under organic management. Treatments were carried out at callusing, rooting and callusing+rooting. Effects on the host-plant morpho-physiological characteristics were observed and depended on the type and timing of Trichoderma application. Treatment at rooting was the most effective whilst application at callusing and combination of treatments gave controversial results. The most noticeable effect of application of Trichoderma was an increase of quantitative-qualitative characteristics of the root system, with a consistent development of...

Effects of Trichoderma harzianum applications on fresh pruning wounds in Actinidia deliciosa for the protection against pathogens associated with the “wood decay” of kiwifruit
Provedor de dados: 21
Autores: Neri, L.; Baraldi, R.; Osti, F.; Di Marco, S.
A chronic wood wasting disease of kiwifruit (Actinidia deliciosa) has recently been identified in Italian kiwifruit vineyards. This disease is principally caused by Phaeoacremonium aleophilum and Fomitiporia mediterranea. The “wood decay” causes a reduced productivity and longevity in the vineyards and influences the quality of the final product. “Wood decay” has a high incidence throughout the vineyards, and is difficult to eradicate once present, leaving prevention as the best defence strategy. The different pathogens causing the disease infect the plant mainly through pruning wounds. We studied a commercial formulation of Trichoderma harzianum T22 for the protection of pruning wounds, and thus for the prevention and reduction of the infection. The...

Autores: Fischer-Arndt, Meike; Neuhoff, Dr. Daniel; Köpke, Prof. Ulrich.
Quality requirements for raw edible produce like lettuces include nutritional value and hygienic quality. Organic lettuce is often considered to cause a potential health risk for immunocompromised individuals due to assumed pathogen transfer from organically manured soils into lettuce heads (Lactuca sativa, var. capitata). The effect of different weed management strategies (rotary tiller, mouldboard plough combined with flame weeding, plastic mulch and straw layer, resp.) on pathogen transfer from fresh and composted farm yard manure were assessed in four field experiments in 2006 and 2007. Results gave no hint on any pathogen transfer given by the assumed pathways (contaminated soil particles transported by mechanical tools and/or splash effect of rain...

Effects on herbicides on hedgerow biodiversity
Provedor de dados: 21
Autores: Strandberg, Beate; Christensen, Kimmie K.
Low dosages of herbicides may reduce the number of flowers on non-target plants. Effect of herbicides on flowering and on pollen and nectar production are relevant end-points for effect assessment on non-target species. Herbicides have the potential to reduce the number of flowers in hedgerow vegetation and thereby also decrease the availability of pollen, nectar and seeds that are important food for many insects and birds. The biodiversity of hedgerow bottom vegetation is lower at conventional than at organic farms, presumably as a consequence of the herbicide use.

Effekt af tekstur og struktur på roddybden
Provedor de dados: 21
Autores: Munkholm, Lars J.; Andersen, Mathias N.
Dybdegående rodvækst giver en række fordele både i relation til planteproduktion og miljø. Der kan opnås en bedre udnyttelse af næringsstoffer og vand, et øget potentiale for biologisk omsætning i dybere jordlag og der ophobes kulstof i dybere jordlag. Rodudviklingen er i høj grad betinget af naturgrundlaget ( klima, jordtype og jordbundsudvikling), men afhænger også stærkt af dyrkningen (jordbearbejdning, trafik, gødskning, vanding, dræning,, kalkning mv.). Jordfysiske faktorer er ofte af dominerende betydning for rodudviklingen i dyrkede jorde. Mekanisk modstand har meget stor betydning for rodvæksthastighed og –nedtrængning, men er samtidig en meget sammensat størrelse, som påvirkes af bl.a. tekstur, struktur, volumenvægt og vandindhold, der igen...

Det er foreløpig undersøkt 4 par i hver gruppe. FK førte til signifikant mindre rauting blant kalvene, (p = 0,001) og videre til at kalver lå signifikant mer i dagene etter separasjonen (p = 0,006) sammenlignet med HK. Generelt ble det observert mindre alert adferd ved denne separasjonsmetoden hos kalvene (p &lt; 0,0001). FK-kalver viste også sjeldnere adferden urolig/vandring sammenlignet med HK kalvene (p &lt; 0,0001). Dette samsvarer med funn av andre som har vist at separasjon med fortsatt mulighet til fysisk kontakt minsker kalvenes rauting og vandring (Haley, 2006; Price et al., 2003; Stookey et al., 1997). Rauting og bevegelse kan gjenspeile motivasjon til gjenforening, noe som ved FK fortsatt var mulig. For kalven kan FK separasjon uten avvenning...

Et kontinuerlig beiteforsøk med 3 perioder à 3 uker ble gjennomført med 16 NRF-kyr i midtlaktasjonen. Målsetningen var å sammenligne melkequalitet når kyrne beitet rødkløvergras (RB) eller botanisk allsidig beite (AB). beitetype hadde ingen effekt på ytelse, melkas fettinnhold eller proteininnhold. Kyr som beitet RB hadde en høyere andel av fettsyrene C18:0 (22.41 vs. 9.96, P&lt;0.05) og C18:1t11 (0.58 vs. 0.44 g/100g FAME, P&lt;0.05) og lavere andel C16:0 (27.83 vs. 30.92, P&lt;0.05) i melkefettet sammenlignet med kyr som beitet AB. Innholdet av alfatokoferol var høyere i melk fra RB enn AB (3.01 vs. 2.64 µg/ml, P&lt;0.05). Den oksidative stabiliteten av melkas lipider ble bare i mindre grad påvirket av beitetype.

In a field experiment with five different main crop rotations and fives subtypes for organic biogas systems, aggregate stability, organic carbon, total nitrogen and pH were evaluated in the topsoil layer (0-5 cm) in April 2010 in a winter wheat stand. Aggregate stability reacted on variation of crop rotation but not on manuring with biogas slurry. Rotations with a higher percentage of legumes led to a higher aggregate stability. Nitrogen reacted in a similar way while organic carbon and pH were more influence by soil inhomogeneity.

Effekte der Düngung mit Rohphosphat und elementarem Schwefel auf Körnerleguminosen
Provedor de dados: 21
Autores: Lehner, Daniel; Starz, Walter; Pfister, Rupert; Rohrer, Hannes.
Körnerleguminosen spielen in der ökologischen Landwirtschaft eine wichtige Rolle, einerseits als hochwertige Proteinquelle, andererseits als zentrales Element der Fruchtfolge. Die Auswirkung der Düngung mit Rohphosphat und elementarem Schwefel auf die vier bedeutenden Körnerleguminosen Ackerbohne, Körnererbse, Lupine und Sojabohne wurde untersucht. Diese beiden wichtigen Nährstoffe können bei gemeinsamer Ausbringung sich in der Wirkung gegenseitig positiv beeinflussen. Das erste Versuchsjahr brachte keine signifikanten Unterschiede in den Ergebnissen, aber eine positive Wirkung des Elementarschwefels.

Autores: Stein-Bachinger, Karin; Haub, Almut; Gottwald, Frank.
In den letzten Jahrzehnten hat ein dramatischer Artenrückgang in landwirtschaftlichen Regionen stattgefunden und eine Trendwende ist nicht in Sicht. Trotz vieler Belege für die positiven Auswirkungen der ökologischen Landbewirtschaftung auf die Biodiversität gibt es keine neueren, quantitativen Literaturstudien im Vergleich zu konventioneller Bewirtschaftung, in denen statistische Parameter Berücksichtigung fanden. In diesem systematischen Review wurden die Effekte beider Bewirtschaftungssysteme auf  ausgewählte Artengruppen verglichen. Wir beziehen uns auf 64 Studien, in denen die mittlere Artenzahl und Abundanz untersucht wurden. Die Auswertung ergab deutlich positive Ergebnisse der ökologischen Bewirtschaftung auf die Flora (85-100 %) und Fauna...

Effekte der Saatgutimpfung im ökologischen Soja-Anbau unter  den Umweltbedingungen nördlicher Breiten
Provedor de dados: 21
Autores: Kühling, I.; Hüsing, Bianka; Bome, N.; Trautz, Dieter.
Driven by an increasing demand for GMO-free soya as food or fodder, the production of organic Soybeans increases, also in high latitudes. As a legume crop, soya needs  specific rhizobia bacteria to be supplied by biological nitrogen fixation (BNF). Since most soils lack the soy-specific strains, bacteria material is usually added manually. We set up a field trial with 5 site-years to investigate the benefit of this inoculation procedure in two different environments (humid, Germany/semi-arid, Russia) under organic farming conditions. Overall 5 different varieties were used (at each site 2 individual and 1 joint) to compare inoculation against untreated control. Leaf  chlorophyll as indicator for BNF was determined by a SPAD-502. To make the SPADmeter...

Autores: Hofbauer, Michael; Bloch, Ralf; Gerke, Horst H.; Bachinger, Johann.
Organic farming on sandy soils in Brandenburg is especially vulnerable to climate change impacts like drought and heavy rainfall. Reduced tillage is considered as one possible adaptation measure. For technical implementation the ring cutter allowing shallow non-inversion tillage with overall root-cutting is under investigation. Its effects on soil bulk density, soil organic matter content, root mass and soil water retention as well as the yield of winter rye were quantified. Results from the spring showed a significant accumulation of organic matter in the tilled top layer and both a significant increase of bulk density and a significant decrease of root mass in the non-tilled lower topsoil. Water retention in the non-tilled layer was reduced. The yield of...

Provedor de dados: 21
Autores: Starz, Walter; Kiendler, Stefanie; Steinwidder, Andreas; Lehner, Daniel; Pfister, Rupert; Rohrer, Hannes.
Schwefel ist ein wichtiger Pflanzennährstoff und die Immissionen aus der Atmosphäre gingen seit 1980 stark zurück. Unter diesen Rahmenbedingungen wurde der Einsatz eines elementaren Schwefeldüngers ("Sulfogüll plus" von BvG) auf einer 4-schnittigen Dauerwiese getestet. Vier Schwefeldüngungsstufen von 0 (S0), 30 (S30), 60 (S60) und 90 (S90) kg S/ha stellten die Varianten dar. Variante S60 und S90 erreichten die signifikant höchste TM- (S60 10.779 und S90 11.073 kg/ha) XP- (S60 1.749 und S90 1798 kg/ha) und Energie-Erträge (S60 64.008 und S90 65.370 MJ/ha) im Vergleich zur Variante S0 (TM: 9.947 kg/ha, XP: 1.569 kg/ha, Energie: 58.434 MJ NEL/ha).

Firm soil mulch husbandry, especially direct seeding, may provide an opportunity for Organic Agriculture to increase soil fertility by efficient erosion control and save labour and energy. In this context, occasional direct seeding (oDS) of faba bean into a straw mulch of residues from precrop oats should be scrutinized. A one-factorial field trial with four replicates was carried out 2010 at the organic research farm Wiesengut of the University of Bonn in Hennef/Sieg. Direct seeding was performed into mulch layers of 0, 4 and 6 t ha-1 of straw residues, respectively. Mouldboard ploughing combined with conventional seedbed preparation was used as control. Compared with the oDS treatment without straw residues, oDS treatments with straw residues (4 and 6 t...

An organic long-term-field experiment with two factors has been carried out since  1998 at the experimental station Gladbacherhof, University of Giessen. Effects of  different crop rotations combined with tillage treatments (mouldboard plough, twolayer-  plough and tillage without plough) on plants, soil and weeds have been  investigated. This article presents results on cash crop yields and weeds according to  soil tillage. It can be concluded that, as for the yields, reduced tillage systems could  cope with the regularly ploughed reference system if at least a shallow soil inversion  was carried out. Concerning the lower yields in the soil tillage system without  ploughing the impact of nutrient availability seems to be more important than the...

E vitamin er nødvendig for drøvtyggere for å opprettholde et velfungerende immunsystem, høyt reproduksjonsnivå, og god melk- og kjøttkvalitet. Innholdet av antioksidanter i råmelken påvirker absorpsjonen av antistoffer hos nyfødte kalver. Selen-innholdet i jord kan være lavt, og dermed kan hjemmedyrket grovfôr være fattig på selen. Hvis grovfôret også er fattig på E-vitamin, som samhandler med selen i sine biologiske effekter, kan underforsyning lett oppstå. Derfor blir rasjonene til drøvtyggere supplert med syntetisk produsert E-vitamin for å sikre tilstrekkelig inntak. Det er imidlertid kjent at syntetisk E-vitamin består av 87,5 % molekyler med ikke-naturlig konfigurasjon og som biologiske ikke er like effektiv (Jensen &amp; Lauridsen, 2007). Av denne...

La réglementation de l’élevage ovin en mode biologique (MB) limite l’incorporation du concentré à un maximum de 40% avec un accès obligatoire au parcours. En Tunisie, la viande d’agneau de race Barbarine élevé sur parcours est reconnue par une meilleure qualité nutritionnelle (MajdoubMathlouthi et al., 2010). Néanmoins, la qualité du parcours est très dépendante de la pluviométrie, et il parait bien impératif de trouver d’autres types de pâturage pour réussir l’élevage en MB. L’objectif de cette étude était d’évaluer la qualité de la viande d’agneaux élevés sur deux types de pâturage: le parcours naturel et une prairie d’orge en vert.

In Italian vineyards it is common to find  more or less extended areas with chemico-physical or  biological soil deficiencies and problems in plant vigor  and grape production. A reduced agronomic functionality  is caused by wrong soil managements and  improper land preparation before vine plantations. A  strong land transformation alters, in fact, the existing  natural balance, causing loss of organic matter and  nutrients, erosions, reduction of available water and  metal accumulation. This phenomenon affects the  growth of vines and the grape yields. The aim of this  work is to evaluate the effect of degraded soils on the  vineyards of two Tuscan vine-growing regions  (Chianti Classico and Maremma Toscana).

However, potential side-effects such as lenti-cell spot development need further investigation. At present, potassium bicarbonate is considered by the Swiss registration authorities as non-toxic to humans and in consequence, no residue levels have been specified. Armicarb has very interesting properties as a plant protection agent and its composition and risk profile are expected to fulfil the IFOAM standards for acceptance of novel plant protection...

The Colorado potato beetle (Leptinotasara decemlineata Say) is one of the most important pests on potatoes (Solanum tuberosum). In the present study, we compared the efficacy of three biological insecticides – Neem (NeemAzal-T/S), pyrethrum/rapeseed oil (Spruzit Neu) and Bacillus thuringiensis var. tenebrionis (Novodor FC) – against this pest in field trials conducted from 2005 to 2007. The combined and temporarily shifted application of neem and B.t.t. reduced significantly the number of beetle larvae and the percentage of defoliation due to larval feeding, and increased the potato yield considerably. The SIMLEP3 forecasting model is useful for determining the optimal timing of the treatment. Pyrethrum/rapeseed oil did not lead to a significant reduction...

Provedor de dados: 21
Autores: Vergnani, S; Caruso, S; Boselli, M; Pasqualini, E.
During the period 1999 to 2007, numerous field trials were carried out in the Emilia Romagna region in order to test the efficacy of Cydia pomonella Granulosis Virus-based (CpGV) products in controlling codling moth, Cydia pomonella (L.). The trial results demonstrate that CpGV-based products can be considered among the best larvicides currently available on the  market. Good results were achieved against I generation larvae, while applications against successive generations did not always provide satisfactory control.

Autores: Daniel, Claudia; Wyss, Eric.
The efficacy of different insecticides (neem, pyrethrin, spinosad, and rotenone) and a repellent (kaolin)  applied with different strategies (single or repeated applications) against the over-wintering pear  suckers (Cacopsylla pyri) and nymphs of the first generation was tested in a field trial in Switzerland  in spring 2003.  Rotenone, the only admitted product in Swiss organic agriculture, showed good effects. But, since  Rotenone is toxic for non-target insects we looked for an alternative. The application of spinosad  (Audienz) in combination with rape oil (Telmion) as well as the application of pyrethrum showed  similar efficacy as rotenone. Neem had no or a very low impact on the pear sucker populations. The  repellent kaolin (Surround® WP) showed...

Efficacy of products allowed in organic olive farming against Bactrocera oleae (Gmel.)
Provedor de dados: 21
Autores: Iannotta, Nino; Belfiore, Tiziana; Noce, Maria Elena; Perri, Luigi; Scalercio, Stefano.
In organic olive farming one of the most problems is how to control the olive fly. The present study has been performed in two different Calabrian olive areas in order to test some active molecules allowed by regulation concerning organic farming. The tested compounds were Rotenone, Azadiractin, Copper, Kaolin and Propolis. The results showed that, at harvesting time (end of October), the lowest infestation has been registered on the trees treated with Propolis and Kaolin in both investigated fields. The obtained results display that the restraining of the active infestation of Bactrocera oleae within limits of 20%, compatible with a quality production, turns to be possible also in Southern olive areas.

Efficacy of Quassia extract on the apple sawfly Hoplocampa testudinea Klug
Provedor de dados: 21
Autores: Kienzle, J.; Zimmer, J.; Maxin, P.; Rank, H.; Bathon, H.; Zebitz, C.P.W.
The efficacy of Quassia extract with a standardized content of Quassin was proved in various field trials in  different regions during three years. The amount of Quassin of 6 g/ha/m tree height will be recommended to  practice. It is not important to have a contact effect on the eggs. The larvae must feed on the product before  they enter the fruit. There is a very good efficacy on primaray infestation. Furthermore, there is even an efficacy  on secondary infestation. Thus, even if due to difficult conditions during application or not optimal termination  of the treatment the efficacy on the primary infestation is not entirely sufficient, the secondary infestation  will be controlled better.

Efficacy testing of novel organic fungicides and elicitors: from the lab to the field
Provedor de dados: 21
Autores: Schaerer, Hans-Jakob; Amsler, Thomas; Thürig, Barbara; Tamm, Lucius.
Novel organic fungicides and elicitors against downy mildew on grapevines were evaluated on grapevine seedlings in a series of indoor screening experiments under controlled conditions and, if they have shown a good efficacy indoors, in a screening vineyard under field conditions.   From 39 products tested under controlled conditions 10 were further examined under field conditions.  All of the new products tested under field conditions showed at least partial efficacy. However, the efficacy was not good enough to protect grapevine plants sufficiently from downy mildew. For a complete re-placement of copper in plant protection against downy mildew on grapevine in organic agriculture, additional new products are needed.

Günümüzde organik ürünlere olan talep gittikçe artmaktadır. Organik hayvansal ürünler kaliteli, kalıntı içermeyen, refahına özen gösterilen hayvanlardan elde edildikleri; çevre dostu koşullarda üretildikleri, lezzetli ve yağ içerikleri daha düşük oldukları için tercih edilmektedirler (Kouba, 2003; Van Ryssen, 2003). Organik hayvan yetiştiriciliğinde hayvanlar organik yemlerle beslenmeli ve üreticilerin kendi çiftliklerinde yetiştirdikleri organik yem maddelerinin kullanımı esas olmalıdır. Ancak organik hayvan yetiştiriciliğinde organik yem gerek dünyada ve gerekse ülkemizde yeterli bir üretim miktarına sahip olmadığı gibi Türkiye’de organik yemlerin yem değeri açısından da ciddi problemleri vardır.

This report was presented at the UK Organic Research 2002 Conference. Established for 8 years, this project evaluates the practicalities of organic beef and sheep production on an upland farm in an ESA. Grassland productivity, stocking rates and animal performance are closely related to seasonal variations in the clover content of the small area of improved land. Improving sales have been offset by increasing input costs. Subsidy payments assist financial performance, but ESA prescriptions effectively prevent increased production.

Die Kraut- und Knollenfäule der Kartoffel (Phytophthora infestans) kann im ökologischen Kartoffelanbau bislang nur durch die Anwendung von Kupferpräparaten effektiv kontrolliert werden. Im Rahmen eines Projektes zur Reduzierung des Kupfereinsatzes wurden mögliche kupferfreie Alternativen zur Blattapplikation gegen Phytophthora-Befall identifiziert. Da infizierte Pflanzknollen Ausgangspunkt für Krautfäule-Epidemien sind, sollen die Mittel nicht nur das Ausmaß des Blattbefalls während der Saison verringern, sondern auch die Menge der in den Boden eingewaschenen und auf die neuen Knollen verfrachteten Phytophthora-Sporen. In Labor-, Gewächshaus- und Freilandversuchen wurden kommerzielle und nicht-kommerzielle Präparate auf ihre Eignung als Kupferalternativen...

As already shown in former investigations, thermal treatment with a hot water/steam mixture can be an appropriate method to control dock plants (Rumex obtusifolius). Thereb,y the application method can be a key technique to acquire both good treatment effects and low working time and energy requirements. Five application techniques were compared in this investigation. A nozzle with rotating pencil jet was identified as the one with the best performance. This variant requires 1.6 l of 90 °C hot water per plant, applied at mean 15 seconds. The average fuel consumption to heat the water came up to 0.016 l Diesel per plant.

The Aim of this study has been to evaluate in two two-year field trials the pre-crop effect of different grain legumes (e.g. soy bean, peas or lupines) in the same environment and to detect possible effects of grain legumes on the N-supply, the yield potential and the yield structure of the  subsequent crop winter wheat. According to different pre-crop yields, a higher but different nitrogen supply for subsequent winter wheat was observed in all N2-fixing pre-crop treatments. In contrast to non-fixings control higher NO3-N contents in soil and higher yields in subsequent winter wheat (up to 24 dt*ha- 1 surplus) were observed.

Traditional intercropping systems with maize and climbing beans have the potential to improve the protein- and energy supply from locally grown roughage. As previous field  experiments at the Thünen Institute of Organic Farming have shown, the crude protein content of maize silage can be enhanced by intercropping with climbing Phaseolus  beans. Since 2014 further field experiments are conducted, that aim to optimize bean yield and fodder quality in intercropping with maize. Therefore four cultivars of  Phaseolus vulgaris (Pv) and two cultivars of P. coccineus (Pc) are evaluated for their intercropping potential. Furthermore, the influence of varied seed densities on bean  yield and crude nutrients are evaluated for two selected bean cultivars. The...

Wie jede andere Leguminose, kann auch die Sojabohne (Glycine max (L.) Merr.) mit Hilfe von Soja-spezifischen Knöllchenbakterien (Bradyrhizobium japonicum) Luft-Stickstoff binden. Da die Bradyrhizobien natürlicherweise nicht in den mitteleuropäischen Böden vorkommen, müssen die Samen der Sojabohne mit kommerziell verfügbaren Bradyrhizobien-Impfpräparaten inokuliert werden. Beim Anbau hat sich in den letzten Jahren jedoch gezeigt, dass die Inokulation vor allem in kühleren Klimaten bei einzelnen Präparaten zu unzuverlässiger Knöllchenbildung und damit ungenügender Stickstoffbindung führen kann. Ziel dieser Arbeit ist es, die Eignung kommerziell verfügbarer Bradyrhizobien-Impfpräparate zur Inokulation der Sojabohne zu prüfen.

In Europe soybean (Glycine max (L.) Merr.) has gained attention due to its ability to produce high quality protein for human and animal consumption. Under low temperature conditions in Central Europe the inoculation with different Bradyrhizobia inoculants has lead to unsatisfying nodulation results. The aim of this study was to test the ability of commercially available inoculants under cool growing conditions in Central Europe. In 2011 and 2012 four Bradyrhizobia inoculants were tested on three early soybean varieties in a field trial in Germany. The number of nodules was assessed six weeks after sowing and at flowering. Yield and protein content were determined at harvest. Product 1 was inefficient to produce nodules, resulting in a severe reduction in...

Faba Beans contain certain non-nutritive compounds that can reduce digestibilty and palatabilty in rations for weaner pigs. Germination has been reported to reduce those  components. The feeding trial took place with 160 weaner pigs that were assigned to one out of four diets with either 19 % pea (KGER), 16 % raw faba bean (KGAB), 16 %  germinated faba bean (VG16) or 24 % germinated faba bean (VG24). Faba beans were germinated for 4 days. Most of the essential amino acids decreased due to germination, the pattern relative to lysine remained the same. There were no  significant differences in live weight on day 8, 15, and 22. At the end of the trial live weight of VG24 was significantly reduced as compared to KGAB and KGER, but not to VG16.

Oil flax was cropped in Switzerland in former times but seldom today. To investigate  new varieties with respect to their agronomic performance and suitability for the  production of cold-pressed oil, 15 varieties of spring flax were tested in the years  2005-2007 at one site. They were sown in small plots with four replicates and  managed according the rules of Swiss organic farming.  Averaged over the years, seed yield of the varieties ranged from 1.4 - 1.9 t/ha.  Pressure of pests and diseases were generally low and weeds were controlled  successfully by mechanical means. In order to recommend flax varieties for the  production of oil, oil quality aspects need to be considered and investigated carefully.

Conventional agricultural and forestry use of wetlands require increasing drainage intensity. Due to drainage, cultivation and fertilization, wetlands emit large amounts of nutrients into adjacent ecosystems, and greenhouse gases into the atmosphere. Associated with these processes are the degradation of the organic soil and the loss of biodiversity.  We have developed a Decision Support System (DSS) that provides basic information to farmers and planners to enable them to use peatlands in a more sustainable way by conserving peat. The DSS proposes adapted conventional and alternative land use options both for peatlands currently used for agricultural purposes and uncultivated, degraded ones.  The DSS is based on a modular concept. Dichotomous decision...

Die Qualitätsbeurteilung pflanzlicher Produkte aus unterschiedlichen Anbauverfahren stößt immer wieder auf die gleichen Probleme:  Nach SCHUPHAN (1961) setzt sich die Qualität eines Nahrungsmittels aus drei Haupt-eigenschaften zusammen: Äußere Beschaffenheit (z.B. Handelsklassen), Gebrauchswert (d.h. technische Verarbeitbarkeit) und biologischer Wert, welcher die Addition aller wertgebenden abzüglich der wertmindernden Inhaltsstoffe darstellt. Diese Summation der Inhaltsstoffe kann zur Qualitätsbeurteilung jedoch nicht ausreichen, da immer nur ein Bruchteil der Pflanze und nie die Pflanze als Ganzheit gesehen wird, ein Problem, welches schon des öfteren diskutiert wurde (u.a.

To determine the current control measures for strointestinal nematodes (GIN) on Swiss organic small ruminant farms, a phone questionnaire was developed and conducted. The survey also aimed to assess the understanding and implementation of  possible alternative GIN control options. In total, 52 meat sheep and 58 dairy goat farm questionnaires were completed, and it was found that in general, farmers were aware of the potential benefit of an adequate grazing management to reduce GIN infection. However, practical realisation was often limiting. On average it was stated that adult meat sheep and dairy goats were drenched 1.5 and 1.3 times per animal and year, respectively, whilst lambs and kids were treated 1.6 and 1.3 times per animal and year, respectively....

The purpose of the present study was to test an organic feed for chicken production. Different feed mixtures with reduced dietary energy level (&lt; 12 MJ AME/kg) and reduced content of essential amino acids were investigated. In case of reduction a constant ratio of amino acids to energy was considered. Under the future European law for organic products all raw materials used for the feed were of organic origin.  The feed consumption of the different feeding groups ran conversely proportional to the diets energy level. The obtained fattening performance and carcass yield reached a high level under the circumstances of organic production.

Autores: Plesch, Gudrun; Wittmann, Margit.
The innovative concept of combining full-time grazing with automatic milking generates various questions concerning herd management. Especially the calving period influences the efficiency of pasture use as well as the degree of energy imbalances of cows. Calving during grazing period leads to reduced milk yields in the first period of lactation, pointing out nutrient deficiencies. Therefore individual calving strategies are needed to optimize pasture exploitation and to increase milk production.

Einfluss der Bearbeitungsintensität beim Umbruch von Leguminosen-Grasgemengen auf die N-Mineralisierung zur Folge-frucht Winterweizen
Provedor de dados: 21
Autores: Wald, Fabian; Pekrun, Carola; Claupein, Wilhelm.
Einleitung  Leguminosen-Grasgemenge sind als N-Quelle in Fruchtfolgen des Organischen Landbaus von zentraler Bedeutung. Nach meist mehrjährigem Anbau wird der von den Leguminosen assimilierte Stickstoff mit dem Umbruch der Narbe durch die Mineralisation der organischen Substanz wieder freigesetzt. In der Praxis steht für eine Steuerung der Mineralisierung ausschließlich das Instrument der Bodenbearbei-tung zur Verfügung. Ziel dieser Untersuchungen war es, die Beeinflussbarkeit der N Mineralisierung durch eine Variation des Narbenumbruchs zu quantifizieren, um so eine Datengrundlage für die Modellierung der N-Dynamik in Abhängigkeit von der Bodenbearbeitung zu schaffen.

Root nodules arise because of symbioses between higher plants and N2-fixing soil bacteria. Legumes and Rhizobium as well as actinorhizal plants and Frankia are known for their symbioses. Nodules of black alder (Alnus glutinosa L.) and black locust (Robinia pseudoacacia L.) were investigated with soil monoliths (30 cm deep and 7 cm in diameter) from agroforestry strips (organic and integrated management).  The farming system had significant influence on the nodule number of black alder, but no influence on nodule number of black locust. For further research and evaluation the  other nodule traits, soil conditions and root biomass will be used.

In the DOK long-term field trial in Switzerland comparing bio-dynamic, bio-organic, and conventional farming systems, the occurrence of Fusarium species and Microdochium nivale on grains of wheat was investigated from 1997 to 2003. Although no differences between the farming systems were found, the previous crop, the fertilisation level, and the year significantly influenced the disease incidence. In 2003, the effect of the pre-crops potatoes versus silage-maize on fusaria was compared. As expected, the incidence of fusaria was significantly higher after maize compared with potatoes. However, the main responsible species was not F. graminearum but F. poae. This species is known for the production of hazardous toxins. A greater input of fertiliser resulted...

Autores: Mainer, Verena; Schmid, Harald; Vogt-Kaute, Werner; Steber, Helmut; Ebertseder, Thomas.
Zusammenfassung  Der Zwischenfruchtbau stellt für den ökologisch wirtschaftenden Betrieb eine wichtige Stellgröße im Management der Bodenfruchtbarkeit dar. Ein hoher Biomasse-Aufwuchs sowie eine intensive Durchwurzelung sind dabei maßgebliche Kenngrößen. Hierbei stellt sich die Frage welches Verfahren zur Bodenbearbeitung und Saat geeignet ist, um einen wirksamen Zwischenfruchtbestand zu etablieren. Im vorliegenden Parzellenversuch wurden sechs verschiedene Zwischenfruchtmischungen mit je zwei unterschiedlichen Bodenbearbeitungs- und Säverfahren kombiniert. Es wurde sowohl der Sprossertrag als auch die Wurzelmasse und -verteilung gemessen. Die Ergebnisse zeigen deutlich, dass die Bestellverfahren einen ertragswirksamen Einfluss auf die Zwischenfrüchte...

After mulching of winter pea on 1st of May 2007 for green manuring four different  varieties of millet were sown without any tillage directly into the mulch cover or after  tillage by a rotary harrow on a brown earth (Cambisol) near Dresden, Germany. Due  to deterioration of soil structure through the impact of rain after tillage seed  emergence, plant height and grain yield of millet were reduced in tilled compared to no  tilled plots. Although the content of mineral N in the soil was much higher after rotary  harrowing nitrogen use efficiency of millet was significantly higher when growing  without any tillage. This effect could be caused by a higher ratio of NH4-N to total  mineral N in the soil which can be an advantage for plant growth with respect to...

Organic manuring with slurry from biogas plants may contribute to plant nutrition and maintenance of soil fertility in organic farming. However, the chemical properties of biogas slurry depend markedly on substrate input and process technology. The aim of this study was to gain more insights into the relationship between the quality of biogas slurry and its influences on plant and soil parameters when applied as organic ma-nure. We studied the effects of slurries from two different biogas plants on yield of maize and soil microbial activity in a two-year field experiment. The investigation took place on a loam-clay soil near Göttingen, Lower Saxony. Biogas slurry A was obtained from a biogas plant with liquid pig manure as main input, slurry B originated...

In stockless organic farming, crop rotation is one of the most important factors that determine the success of crop cultivation. Six crop rotation schemes in a long-term experiment of the Bavarian State Research Center of Agriculture at Viehhausen allow the estimation of the effect of crop rotations on grain yield and baking quality of winter wheat. The three and five years crop rotations differed in the utilization of grass clover swards (cutting or mulching), in the following crops (potatoes or barley), in the portion of grass clover swards and in the type of legume (grass clover or grain legume).The lowest grain yield as well as the most inferior baking quality was shown after grain legume. The highest yield was obtained after the two-year grass-clover...

The preceding crop effect of fodder legumes concerning sowing date, type of legume and utilization were conducted in field trials at two sites in Upper Bavaria in 2012-  2013. All in all, seven types of clover in pure stands or clover/grass leys were grown one main production year. Sowing dates were undersowings in triticale in spring,  stubble seeds after harvest of preceding crop triticale and spring seed in the main production year. Utilization variants were mulching or cutting without organic  fertilization in the subsequent crop winter wheat.  Mulching of fodder legumes resulted in higher yields and mostly higher baking quality (crude protein content, wet gluten content and baking volume) of the succeeding  wheat. Earlier sowings leaded mostly to...

Four layer-mash rations based on 100% agricultural feedstuffs of organic origin and  with different levels of energy content were tested at the University of Kassel some  years ago. The rations had different parts of inland feedstuffs (grain, grain legumes,  grass meal) and components from foreign countries (soybean, sesame cake). High  energy compositions had a larger part (ca.28%) of foreign feedstuffs. The part of  foreign components could be reduced about 10% by decreasing energy content.  Ascending costs for the feedstuffs resulted in greater increase of costs for those mixtures  with greater amounts of foreign feedstuffs. It would be necessary to search for  more solutions in order to strengthen inland feedstuff production and regional organic...

Several studies show that polyphenol oxidase (PPO) in red clover reduces proteolysis and increases nitrogen use efficiency of the ruminant, but not much is known about factors affecting PPO activity in red clover plants. PPO activity was analysed in red clover plants from legume-grass mixtures subjected to three different management systems. The cutting frequency (3 or 5 cuts) caused only minor differences in PPO activity, whereas a significant increase in PPO activity could be proved for the rota-tional grazing system (RG), compared to the simulated grazing system (SG, 5 cuts) with equal use frequency. Results indicate a metabolic adaptation of the red clover plants due to the grazing process itself, leading to a control factor which has to be considered...

Below-ground plant N (BGN) of grain legumes is an important N pool for subsequent crops. Especially the easily available rhizodeposits (RD) provide an important N input, which might also be relevant in mixed stands. The objective of the present study was to estimate the time course of the BGN, especially RD-N, and the effect of mycorrhization on RD-N. Therefore, the quantity of RD-N of peas with and without mycorrhiza (Frisson and P2) was estimated at four different growth stages. The results show that the relative contribution of BGN to total plant N was equal in both varieties during the growing season. The contribution of RD-N to total plant N decreased over time. Mycorrhization did not affect the quantity of N-rhizodeposition. Consequences for mixed...

The impact of a common and a reduced seeding rate on grain yield and quality for winter triticale was examined in four growing seasons at two experimental sites in Bavaria. Grain yield was lower for reduced seeding rate only in one of the four years in one environment. In that environment weed controlling was impossible because of high precipitation in autumn and spring. This was resulting in markedly higher weed coverage at reduced seeding rate due to a comparatively lower competitiveness. In all other environments no statistical differences in grain yields were determined because of higher 1000 K weight and higher tillering at reduced seeding rate. Fur-thermore, the crude protein content was higher for reduced seeding rate (9.4 and 8.9 % in DM,...

Four seeding dates (end of March, mid and end of April, onset of May) of soybeans were compared in a yearlong field trial in Bavaria. Soy plants with seeding date at the onset of May were damaged by doves, but only the development was delayed for approximately one week and the number of plants was not influenced. Grain yield and crude protein yield was highest with seeding at the end of April. Seeding at May resulted in significant lower dry matter content and obviously delayed harvest with the risk of a complete loss.

Experiments with peas had been conducted during two years. Four varieties with four plant densities had been tested with respect to yield and weed growth. Conclusions are that the recommended plant density of 80 kernels/sqm is sufficient for yield and less weed-growth. For weed growth the choosen variety is more important than the plant density. Stability till harvest is the most important characteristic of variety for reducing weed growth.

Ammonia emissions from barns have a severe impact on the environment. Especially dairy cattle, kept in loose housing, contribute to the total emission of ammonia up to 50%. Soiled walking areas like slatted floors, are realised as one of the main sources of the emission. In this study, a special cleaning device was used in order to remove manure from a slatted floor in an organically run dairy barn. It was investigated how the combination of a rubber-scraper, mechanical star discharge rotors and high-pressure water nozzles affects the ammonia emission from the floor. Six concrete test elements (55cm x 62cm x 20cm) were cut out of the existing slatted floor in order to be able to separate them from other sources of ammonia emission in the barn. With a...

Einfluss der Stickstoffaufnahme verschiedener Zwischenfrüchte auf die Nitratverlagerung über Winter und die potentielle Stickstoffnachlieferung für die Folgefrucht
Provedor de dados: 21
Autores: Stumm, Christoph; Rohling, Mike; Döring, Thomas.
In Feldversuchen mit verschiedenen Zwischenfrüchten (Phacelia, Grünroggen, Sandhafer, Winterrübsen, Ölrettich, Inkarnat- und Perserklee) wurde das Potenzial zur Reduzierung der Nitratauswaschung über Winter für alle nicht-legumen Arten bestätigt. Aufgrund vglw. hoher Verluste an Stickstoff aus der Sprossmasse über Winter sowie einem weiten C/N-Verhältnis der Zwischenfruchtreste (v.a. Stängel), scheint das Potenzial zur Steigerung der Nährstoffmineralisation im Frühjahr relativ gering sein.

In a field experiment started in August 1998 at the Experimental Station for Organic Farming Kleinhohenheim of the University of Hohenheim the effect of stubble tillage on yield formation and weed control was tested. Three types of stubble tillage were compared to a control which consisted of not cultivating the stubble after harvest. The treatments were: chiselling (15 cm), shallow ploughing (7 cm) and rototillering (5 cm). In autumn all treatments were ploughed at 25 cm depth. So far, stubble tillage has not had any significant effects on weeds or yields. However, there was a tendency of stubble tillage having an impact on perennial weeds.

According to EU-Regulation 889/2008 slow growing strains shall be used in organic farming in order to ensure good broiler welfare. We examined effects of growth speed on broiler welfare in four different strains (33.01±5.8 to 44.02±8.0 g/day) in two batches on nine organic farms that kept two to four strains in parallel. The currently common slow growing strain (44.02±8.0 g/day) was a reference on all farms. In total 5593 broilers in 36 groups with 30 to 565 animals were kept. Live weight, lameness, skin and plumage condition and cleanliness of plumage were investigated on samples of 30 to 81 birds depending on group size. If possible, measures were taken repeat-edly (twice), at an average body weight of 1800 g to 2600 g. Individual data were analyzed...

To investigate the effect of feed transition from barn feeding to pasture on the course of ruminal pH a study with 8 lactating dairy cows was undertaken. Therefore, an indwelling pH-measurement and data transmitting system was used. The experiment started at 27th March 2012 and a gradual transition from barn feeding to pasture feeding was done (periods P1-P6). After 7 days of barn feeding (P1) animals were given pasture progressively with increasing grazing time from 2 to 7 h/d (P2, day 8-14). In P3 (day 15-21) the cows spent 7 hours/d on pasture. Beginning on day 22, animals had 20 h/d access to pasture (continuous grazing), only semi-daily interrupted for 2 hours for milking and additional feeding (P4-P6). During the barn feeding period (P1), average...

Sward height is a key parameter for rotational grazing. Influence of different sward heights (low: 8 cm, medium: 10 cm, high: 12 cm) on DM yield and grass growth rate were investigated on an intensive grazed area at the research farm of the Organic Institute of AREC Raumberg-Gumpenstein during the vegetation period of 2013. The significant highest yields were found in treatment “high” (12,581 kg DM ha-1) and “medium” (12,119 kg DM ha-1). Treatment “low” reached a yield of 10,343 kg DM ha-1. During summer, grass growth rate was about 60 kg DM ha-1 day-1 in average.

In this study slurry, manure and compost from dairy cattle were used on a newly sown meadow. The influence of these three fertilisers on botany and forage yield were tested in a randomized block design. The amount of farm fertilizers was calculated by 1.2 LU ha-1 considering quantity storage losses. No differences between used organic farm fertilisers in botanical composition were found. The highest LAI (4,7 ground level) and the highest dry matter yield of 11,045 kg DM ha-1 were measured in slurry fertilisation.

In a long-term trial in central Switzerland, yield and health of winter wheat was  examined under organic, extensive and intensive management.  In the organic cropping system, soil was ploughed and fertilised with cattle dung. In  the extensive system, soil was cultivated ploughless and dung was supplemented by  mineral fertiliser. Herbicides were used, but no growth regulators or fungicides. In the  intensive system, soil was ploughed and manure was based on cattle dung and  mineral fertiliser with 20 % more nitrogen than in the extensive system. For plant  protection, herbicides, growth regulators and fungicides were used.  In the period from 2004 to 2007, average winter wheat yields of the intensive and the  extensive crop management system exceeded...

Baking quality is a major problem of wheat production in organic farming in Germany. The main reason is low protein content, but also different gluten characteristics. The aim of our investigations was to verify, whether selection of varieties with special adaptation to organic farming (or OF systems with particular low input) is advantageous. 66 Genotypes of winter wheat (registered German varieties, breeding lines, older varieties and varieties bred for organic farming) were compared in 5 environments over two years. Yield, protein content and quality parameters were assessed. Aptitude to LI- or HI- conditions was determined using intravarietal linear regression. While selection for special adaptation proved to be superior for yield and protein yield,...

Mixed cropping peas together with linseed dodder had a significant suppressive effect on weed-coverage, in average 62 % efficacy in 2003 and 54 % in 2004, compared to mono cropped peas. The infestation level of pea aphid (Acyrthosiphon pisum) and the damage incidence of pea moth (Cydia nigricana) in harvested peas, was neither significantly reduced nor enhanced. In both years mixed cropping peas gained a relative surplus in yield compared to peas grown as a sole crop. The results demonstrate the advantageous complementary use of...

Water voles (Arvicola terrestris) and common voles (Microtus arvalis) cause substan-tial damage in organic fruit growing by gnawing at bark and roots of trees. To prevent the immigration of voles into orchards a mechanical drift fence was developed and successfully tested in 2002 and 2003. The effectiveness of the drift fence, consisting of wire mesh reaching 30 cm above the soil surface and up to 30 cm into the ground, was impaired by moles (Talpa europaea) undermining the fence. Voles used these tunnels to immigrate into the protected plots. In a new study supported by “Bund-esprogramm Ökologischer Landbau” and carried out between 2004 and 2006, factors contributing to undermining of drift fences by moles were determined. The results of practical field...

Due to the results of organic matter balancing which showed a very high potential of soil organic matter accumulation in organic farming, a research project was started in spring 2005 with the objective to ascertain this hypothesis. Soil sampling was carried out on different organic and adjacent conventional farms in distinct regions of Ger-many. A comparison of the samples regarding Corg showed only minor differences between organic and conventional farms whereas the more sensitive indicators like Cmic and enzyme activities were more affected. However the main influencing factor of all these indicators in this investigation is soil texture.

Slurry is known as a source of ammonia (NH3), methane (CH4) and nitrous oxide (N2O) emissions. NH3 emissions depend on the pH value of the slurry and previous studies show that emissions could be reduced by lowering the pH. In order to estimate the influence of stirring on the pH and the NH3 emission potential of cattle slurry, three treatments (A not stirred, B stirred for 1 x 60 min and C stirred for 6 x 10 min per day) were compared. The results show that no positive effects of stirring cattle slurry, neither in economic nor in ecological terms, can be expected.

Achieving high baking quality and sufficient yield is often a challenge in organic wheat production. The impact of sowing date (either autumn or spring) was compared regarding grain yield, baking quality and infestation with chloropid gout fly of seven varieties of spring wheat. The field trial was conducted in 2010, 2012 and 2013 on a sandy loam nearby Freising, Bavaria.   Two varieties showed higher grain yield after autumn sowing compared to spring sowing in two of the three years. But the opposite occurred consequently for two other varieties. The other three varieties showed no consistent reaction. This different reaction may refer in the majority to a different infestation with chloropid gout fly. Additionally, a higher baking quality (protein...

For stockless organic farming cultivation of leguminous cover crops is an important source for the nitrogen supply of organic cropping systems. However, too strongly developing living mulch systems may affect the undersown cash crop. At two experimental sites in Bavaria the impact of the sowing date of cover crops on grain yield of the undersown cash crop winter rye and the subsequent crop spring oat was determined in two and three field trials, respectively (2003/04/05 until 2004/05/06 and 2002/03/04 until 2004/05/06, respectively). Living mulch treatments were white clover and grass-clover (alfalfa, red and white clover, diverse grasses) with seeding in autumn and spring as well as red clover and black medick with seeding only in autumn.

Generally, purple-flowered peas are assumed to be less susceptible to soilborne pests. The above- and belowground biomass yield of one purple-flowered and one white-flowered pea were compared on three soils with and without soil fatigue.   Both peas showed lower above- and belowground biomass yield on soil fatigue soils than on unstressed soils. The aboveground yield´s decrease of the purple-flowered pea was higher than for white-flowered pea on two of the three soils. Hence, purple-flowered peas are generally not less susceptible to soilborne pests than white-flowered peas.

Sulphur may be a limited nutrient in organic farming due to reduced atmospheric sulphur deposition. The impact of sulphate fertilization to winter wheat and spring  barley was investigated in two different field trials in South Bavaria over three years. The yield and the crude protein content of winter wheat and the yield of spring barley were not affected by sulphate fertilization. No differences were determined regarding agronomical characteristics and tolerance to diseases between the fertilized and unfertilized plots. The wet gluten content and the loaf volume of wheat were significant higher after sulphate fertilization than without fertilization. Hence, the baking quality, but not the yield may be improved through sulphate fertilization.

Auf dem ökologischen Versuchsfeld am Standort Gülzow wurde in zwei Feldversuchen (2013-2018) der Effekt einer Schwefeldüngung im Kleegras getestet. Schwefelmenge, Ausbringungszeit und Düngerart wurden während des Versuchszeitraumes variiert. Die Ergebnisse zeigten wenige Wochen nach der Düngung einen Anstieg der Schwefelgehalt im Boden. Mit Hilfe der Schwefeldüngung konnte in der Regel sowohl der Leguminosenanteil gesteigert als auch der Schwefel- und Proteingehalt in den Pflanzen erhöht werden. Der Trockenmasseertrag stieg besonders durch Sulfatdüngung im Frühjahr an. Nach Düngung mit elementarem Schwefel waren kaum Effekte nachweisbar.

Einfluss mineralischer K-Düngung und organischer Düngemittel auf Nährstoffversorgung, Ertrag und Qualität von Kartoffeln im ökologischen Landbau
Provedor de dados: 21
Autores: Kolbe, Hartmut.
Die K-Versorgung ist ein wichtiger Einflussfaktor für die Qualität von Kartoffelknollen. Aus vielen Düngungssteigerungsversuchen mit mineralischen K-Düngemitteln ist bekannt, dass die Gehalte an Trockenmasse (TM), Stärke, die organischen Säuren und Vitamin C, einige Mineralstoffe (Kalium, Magnesium) sowie die Widerstandsfähigkeit gegen Beschädigungen und Verfärbungen maßgeblich von der K-Ernährung der Kartoffeln bestimmt werden. Doch ob sich organische Düngemittel verschiedener Herkunft und Zusammensetzung ebenfalls als K-Quelle eignen, ist bisher weder im konventionellen noch im ökologischen Landbau eingehend untersucht worden. In mehrjährigen Feldversuchen wurde daher die Wirkung von mineralischen und organischen Düngemitteln auf die K-Verfügbarkeit im...

Einfluss nachhaltiger Anbausysteme auf die Populationsdynamik  pflanzenparasitärer Nematoden in verschiedenen Klimaregionen Europas
Provedor de dados: 21
Autores: Schmidt, Jan Henrik; Finckh, Maria R.; Hallmann, Johannes.
Pflanzenparasitäre Nematoden können in Abhängigkeit von Fruchtfolge und Bodenbewirtschaftung teils hohe Populationen aufbauen und dann bei anfälligen Kulturarten erhebliche Ertragsverluste verursachen. Dies betrifft insbesondere Arten mit einem breiten Wirtspflanzenspektrum, wie Vertreter der Gattungen Meloidogyne oder Pratylenchus. Im Rahmen des EU FP7 Projektes OSCAR (www.oscar-covercrops.eu) wurde der Einsatz von Minimalbodenbearbeitung, verschiedener Haupt- und Zwischenfrüchte bzw. Untersaaten sowie Düngung (Kompost, N-Dünger) auf pflanzenbauliche und bodenkundliche Parameter untersucht. Hierzu wurden an vier Standorten (Italien, Schweiz, Deutschland und Schweden) jeweils 2 Feldversuche durchgeführt. Jeder Feldversuch bestand aus einer 2-jährigen...

Provedor de dados: 21
Autores: Pekrun, Carola; Schneider, Nicole; Wüst, Christian; Jauss, Fritz; Claupein, Wilhelm.
Problemstellung und Ziele  Reduzierte Bodenbearbeitung wirkt in vielfältiger Weise positiv auf Bodenstruktur, Humusgehalt und Bodenleben und bietet darüber hinaus Vorteile in ökonomischer und arbeitswirtschaftlicher Hinsicht. Im konventionellen Landbau wird seit mehreren Jahrzehnten reduzierte Bodenbearbeitung betrieben. Im Ökologischen Landbau stellt sich die Frage, inwiefern eine Reduktion der Bodenbearbeitungsintensität und –tiefe praktikabel ist.  Arbeitshypothesen  Ein Verzicht auf wendende Grundbodenbearbeitung ist im Ökologischen Landbau nicht durchgängig möglich, da es zu einer starken Zunahme von Unkräutern kommt, insbesondere mit perennierenden Unkräutern. Eine flache Pflugfuche oder der Zweischichtenpflug stellen günstige Verfahren dar, die...

Provedor de dados: 21
Autores: Schulz, D.G.; Koch, K.; Kromer, K.-H.; Köpke, U.
Grundsätzlich sprachen die Kartoffeln der Sorte ´Granola´ sehr schwach auf die eingesetzten Versuchsfaktoren an, sodaß die Unterschiede selten statistisch abgesichert werden konnten.  Bei denjenigen Inhaltsstoffen, die deutlicher auf den Anbaufaktor Düngermenge ansprachen, reagierten die Knollen der mineralisch gedüngten Varianten eindeutig stärker (Abnahme der Trockenmasse, der Saccharose-, Stärke- und Clorid-Gehalte, Zunahme der Glukose-, Fruktose-, Fluorid- und Asche-Gehalte) als die Vergleichsvarianten. Ein Grund hierfür könnte die schnellere Verfügbarkeit des mineralischen Düngers gewesen sein.  Die biologisch-dynamisch gedüngten Knollen zeigten nur bei drei Parametern dieselbe Reaktion auf die Intensivierung der Düngung wie die organisch gedüngten...

The impact of cropping systems on soil phosphorus (P) forms and P dynamics was  studied. The systems were a biodynamic (DYN), a bioorganic (BIO), a conventional  (CON), a stockless system (MIN) and an unfertilized control (NON). These cropping  systems are part of the DOK field trial in Therwil near Basel. The systems differed in  fertilization and plant protection. The P budgets over 30 years were negative except  for CON and increased in the order: NON &lt; DYN &lt; ORG &lt; MIN &lt; CON. A sequential  P extraction scheme was used to characterize the P forms in soil samples from 2007  and 1977 (before the start of the trial). Labile inorganic P (Pi) forms differed significantly  between cropping systems. Organic P forms (Po) and stable Pi forms were not...

The most organic produced potatoes are used for direct marketing or home requirements. But due to the growing demand for “Convenience-products” like potato crisps and chips the production of processing potatoes offers farmers an alternative. In contrast to conventional agriculture the nutrient supply in organic potato production must be secured by preceding crops or organic fertilization. Clover grass as  preceding crop is common in praxis. But as the case may be how the clover grass is utilized  (mulching, cut mowing) a different nitrogen fixation and mineralization is possible. In a period of two years (2003/2004) the effect of different clover grass management systems on yield, grading and quality of processing potatoes was under examination on the...

Field experiments with spring barley (Hordeum vulgare L.) and field pea (Pisum sativum L.) were carried out in three subsequent growing seasons 2004 to 2006 at the Hessian State Estate Frankenhausen located near Kassel in Central Germany. Spring barley and field pea were sown out as sole crops and intercropped with different seed rates in replacement and additive design, using two sowing modes: row by row (IC) and mixed intercropping (MC). Intercropping (IC and MC) was able to increase grain yield in most of the treatments. The Land Equivalent Ratio (LER) was always higher than 1, indicating that plant growth factors were used more efficiently by the intercrop than by the sole crop. Besides, the N content in spring barley grain was increased by...

In field experiments in five Bavarian farms three cultivation systems of onion produc-tion were compared: direct sowing, planting of set onions and planting of seedlings with 7 seeds per each tray. In three of five farms the onions yield up to more than 500 dt ha-1and in average the planted seedling yielded higher than the sown ones. In the other farms, where the set onions where included in the trials, the yields were lower depending on the high and early infection with downy mildew. The plant density (90-70 plant m-2) had more effect on the onion size distribution than on the total yield.

Autores: Schneider, Regina; Salzeder, Georg; Schmidt, Martin; Wiesinger, Klaus; Urbatzka, Peer.
In organic crop rotations proportion, use and type of legumes have a different effect on subsequent crops. The yield of subsequent cash crops is affected by the farming system (livestock with organic fertilizer or stockless) and the temporal distance of the cash crop to the legume. To investigate the intermediate- and long-term effects on yield and productivity, a long-term field trial with six crop rotations was established in 1997 in Viehhausen, Upper Bavaria (one crop rotation with a period of 5 years, five crop rotations with 3 years). The present report tested these crop rotations regarding yield and productivity for the years 2000 to 2010.  Significant differences were determined in productivity when legumes were included into the calculation. Crop...

The pea moth (Cydia nigricana) has developed to the most serious pest in organic green peas in recent years. In 2003 about 20 % of the contracted acreage needed to be rejected by the processing industry, due to the very low tolerance levels requiring at least 99,5 % (w/w) non affected high quality peas. The present study investigated the influence of different sowing dates on the damage level in green peas. In a small scale field experiment arranged in a complete randomized block design with four replicates three common cultivars suitable for early, mid and late sowings, namely Avola, Gonzo, Trompet, respectively, were utilized. Each variety was sown at an early and a late date, resulting in six sowing dates at total, covering the entire sowing period from...

Based on a field trial, the impact of three different viticultural management practices on photosynthetic activity of Vitis vinifera cv. Riesling were compared. The vines were planted in 1991 at Geisenheim (Rheingau, Germany) and the different management practices i.e. integrated (good agricultural practice), organic (EU VO 834/07 and ECOVIN standard) und biodynamic (EU VO 834/07 and DEMETER standard) were established in 2005.  Even though all treatments received the same level of nutrients and water the initial measurements of photosynthetic activity differed tendentially. The integrated and biodynamic treatment showed a slightly higher degree of light saturation, as well as photosynthetic activity, compared to the organic treatment.

Aim of the study was to test possible influences on performance parameters in com-mercial layer farms. 106 flocks at 70 organic farms in Germany were investigated. Egg performance and mortality were collected from farm records. The integument of the hens was assessed with a scoring index (plumage condition and injuries).   Egg performance was higher at bigger farms. These farms showed often a better management (e.g. more health records or feed analyses). However, plumage was scored worse with increasing stock size. Bigger farms had higher densities in the hen house and at equipments like nests, feeders or drinkers. Therefore, more intensive housing conditions could have been the cause of plumage damages.

In order to test the effect of organic vs. conventional diets on fertility traits, we conducted  an on-farm study with female rabbits. Eight groups of seven to eight female rabbits  kept in systems with litter were fed ad libitum with either organic or conventional pellets.  Offspring was weaned with approx. 28 days. In the first series analysed, the  conception rate was higher in the conventional groups. Diet type had no significant  influence on that trait. Nevertheless, a significant influence of diet on litter size was  found: organically fed female rabbits produced more offspring per litter. The organic  groups also showed higher rates of weaned animals, despite of a slightly higher mortality  of offspring in these groups, but differences for both...

Optimierte bodenphysikalische Eigenschaften sind Grundlage der Entwicklung  vitaler Getreidebestände und hoher Kornerträge. Wurzelwachstum und Wurzelaktivität stehen in engem Zusammenhang mit Bodendichte, Porenverteilung, Eindringwiderstand und dem gewogenen mittleren Aggregatdurchmesser. Konventionelle Grundbodenbearbeitung mit dem Wendepflug führt häufig zu ungünstigerem Bodengefüge, im Zusammenhang mit hohen Auflasten, zu Pflugsohlen. Ziel des Projektes war es, den Einfluß verschiedener Bodenbearbeitungssysteme auf bodenphysikalische Eigenschaften und das Wurzelwachstum von Wintergerste unter den klimatischen Bedingungen des Mittelmeerraums zu untersuchen.

The effect of different sources of K and N on graded yields, dry matter, reducing sugars and quality of french fries and crisps, respectively were examined in two maincrop varieties (AGRIA and MARLEN). Fertilizers applied were cattle manure, potassium sulphate (PS), PS + grinded horn, grinded horn (GH) and a control. Results of two-factorial field experiments (2002-2004) on a loamy sand are presented. Cultivar and fertilizer had a significant effect on final yield, combined mineral K and organic N (PSGH) being the most efficient fertilizer with regard to graded yields for crisp (&gt;40 mm) and french fries production (&gt;50 mm). K content of tubers could be increased, but dry matter was lowered by most fertilizers, so that only the unfertilized plots...

Autores: Pitter, Tanja; Vogl, Christian R.
Im Hinblick auf die Richtlinien der ökologischen Landwirtschaft auf chemisch- synthetische Arzneimittel zu verzichten und beispielsweise pflanzliche Heilmittel einzusetzen, scheint eine Einbindung von pflanzlichen Hausmitteln in die Tierheilkunde sinnvoll.  Die Faktoren, die mit dem Hausmitteleinsatz in Verbindung stehen bzw. diesen begünstigen könnten, wurden bisher wenig untersucht. Ziel dieser Arbeit war es einerseits, das Wissen von ausgewählten Bäuerinnen und Bauern zu Hausmitteln zu dokumentieren und andererseits Faktoren zu ermitteln, die positiv auf den Hausmitteleinsatz einwirken könnten. Aufbauend auf die Theory of Reasoned Action von Fishbein und Ajzen wurde ein Modell entwickelt, anhand dessen Hypothesen abgeleitet und Einflussfaktoren geprüft...

Genetische Vielfalt und das Mikroklima innerhalb eines Feldes kann die Entwicklung von Epidemien massiv beeinflussen. In Kartoffelbeständen kann Vielfalt durch Sortenmischungen in der Reihe, alternierenden Reihen oder Streifen verschiedener Sorten (siehe Finckh et. al. 2003, dieser Band) oder im Streifenanbau abwechselnd mit anderen Kulturen erreicht werden. Beim Streifenanbau mit verschiedenen Kulturen sind eine große Anzahl Anbaufaktoren beeinflußbar wie Feldlänge und - breite, Ausrichtung zum Wind und die Art der Nachbarkulturen. Diese können, wenn sie höher als die Kartoffelbestände sind als Barrieren für Wind und Krankheitsinokulum dienen, eventuell aber auch die Bestandesfeuchte erhöhen. Niedrigere Kulturen dagegen können die Bestandesfeuchte...

Common and dwarf bunt of wheat are important diseases in ecological farming. High infection levels lead to an increase of the spore potential in soil. 3 and 4 years  randomized crop rotation field trials are performed at 3 sites with 4 replicates on naturally infested fields with either T. controversa or T. caries spores with crop rotation  links commonly used in organic farming to determine whether it is possible to decrease the spore potential in soil. The influence of stable manure on bunt spores is tested. Brassica species setting free thiocyanate and isothiocyanate compounds after mulching are cultivated to examine the possibility to reduce the spore potential in soil.  Soil samples are taken yearly from each plot and common and dwarf bunt spore...

In a field experiment with five different main crop rotations and fives subtypes for organic biogas systems, aggregate stability, organic carbon, total nitrogen and catalase were evaluated in the topsoil layer in spring 2010, 2011 and 2013 in a winter wheat stand. Aggregate stability was enhanced by variation of crop rotation but not on manuring with biogas slurry. Rotations with a higher percentage of legumes led to a higher aggregate stability. On the other hand catalase activity was improved by biogas slurry.

Provedor de dados: 21
Autores: Leisen, Edmund.
Im Winter 2001/ 2002 war die Clostridienbelastung in der Milch auf vielen Betrieben höher als in den vorangegangenen Wintern. Im Herbst/Winter 2001/2002 wurden die käsereischädlichen Clostridien in Kot und Milch auf insgesamt 96 Betrieben untersucht. Die Hygienebedingungen ließen sich aus dem Vergleich von Clostridienbelastung in Kot und Milch abschätzen. Zur Ursachenklärung gaben die Betriebe Auskunft über die einzelbetrieblichen Rahmenbedingungen. Zur Einschätzung der Futterqualität standen Futteranalysen sowie eine Beschreibung der Silagequalität zur Verfügung.  Der Grund für die häufig höhere Belastung speziell im Winter 2001/2002 ist auf die witterungsbedingt höhere Clostridienbelastung im Futter zurückzuführen. Positiv wirkten Häckseln und der...

Fattening of entire male pigs is a useful alternative to piglet castration but the problem of boar taint is still unresolved. The object of the present study was to test the effect of (i) two different terminal sire lines (Danish Duroc, Du vs. Piétrain, Pi) and (ii) two different feeding strategies (without (-) vs. with (+) raw potato starch prior to slaughter) on the prevalence of boar taint in organic pork production. The results show that entire male growing-finishing pigs of Du origin have significantly higher androstenone concentrations in shoulder back fat than those of Pi origin whereas the feeding strategy has no significant effect. Concerning skatole, both genetic origin and feeding  strategy significantly affect concentrations in shoulder back...

The results confirm the known differences between both genotypes also in intact male growing-finishing pigs. The feeding strategies remained without noteworthy effect. Hence, the choice of terminal sire genotype can completely be adjusted to the requirements of the marketing goal.

Beneficials can prevent or reduce outbreaks of pest species. To strengthen the  populations of beneficials, their food sources must be improved in cultivated areas.  The effects of habitat management for augmenting beneficial population on parasitism  and predation rates of three lepidopteran pest species were investigated on two  organic fields in Alten (Switzerland). The aim was to improve pest regulation through  wild flower strips along fields and by planting Centaurea cyanus as companion plant  within the crop. Strips of Centaurea cyanus and Fagopyrum esculentum increased  parasitsm on the lepidopteran pests. C. cyanus planted as companion plant  furthermore increased predation on the eggs and parasitism of the larvae of Mamestra  brassicae. Several...

The influence of biochar with an amount of 0 to 20 t/ha on growth, yield and ingredients on soybeans of different variants was compared. Differences between the variants until blooming could be found. Plants from the HTC variant have shown significantly longer stems than others. These differences diminished until the harvest. Due to extrem low precipitation values in spring and early summer, no rhizobia could be developed and nitrogen fixation for the soybean was impossible. The plants could only use nitrogen from the soil. As a result, plots prepared with mineral fertilizer have shown the significantly longest plants, highest mass of dry matter and highest yields. Further, HTC variants have shown the lowest values in oil- and sugar contents. The  highest...

Water protection is controlled by specific regulations in the German Federal States, e.g. the SchALVO in Baden-Württemberg. An amendment of the SchALVO demands, amongst others, a changed timing and intensity of soil tillage directly after growing crops with high-nitrogen residues. As Organic Farming highly relies on soil tillage for weed control, there is concern about decrease of yield and increase of weed infesta-tion in water protection areas if tillage is restricted. Field experiments were performed on practical farms with three treatments according to SchALVO (rigid tine cultivator or mouldboard plough for primary tillage, used in October, December or February) and two treatments according to best management practice (mouldboard plough in Octo-ber or...

One hundred Swiss composts and digestates were investigated in order to evaluate  their influence on plant growth and health. Important differences in biological compost  quality and on the impact on soil fertility and on plant health were observed. The most  important limiting factor of compost quality is the possible immobilization of  mineralized nitrogen by some composts. However, quality composts have a good  potential to protect plants against diseases. More attention should be paid to the  control of the composting process in order to improve the biological quality of  composts with more beneficial effects on crops.

For the success of no-tillage in organic farming, new tools have to be developed to control weeds. One possible strategy could be sowing the main crop into an earlier established living mulch of easily controllable cover crops.   Field trials were carried out in the Swiss midlands to investigate the impact of different legume cover crops on weed populations and grain yield of directly drilled winter wheat (Triticum aestivum L.) in a living mulch system. In general, weed suppressing effect was best with highly productive legumes. A significant reduction of the weed density of dicotyle, monocotyle, and spring germinating species was observed. Though, effective weed suppression resulted also in strong competition with the winter wheat. In order to improve the...

Quantification and mitigation of greenhouse gas emissions is an intensively discussed topic. For dairy farms many studies consider a higher milk yield per cow for greenhouse gas mitigation but this often results in a reduction in herd fertility and thus more heifers are needed which may lead to more emissions in total. This paper presents the Product Carbon Footprint of 36 organic dairy farms and analyses the influence of milk yield per cow and longevity of dairy cows. Results are: (1) a product carbon footprint of 1,61 kg CO2eq/kg fat and protein corrected milk on average, (2) increasing milk yield per cow causes decreasing product carbon footprints (coefficient of determination 48 %) and (3) decreasing longevity per cow causes decreasing product carbon...

Late blight, caused by Phytophthora infestans is commonly thought to be the factor most limiting yield in organic potato production. However, because there is no fully effective fungicide available to control late blight, there are virtually no yield loss data available for organic farming conditions.  In large-scale experiments covering 2-6 ha from 2000-2002, late blight assessments were conducted throughout the season in small sections throughout the field. The same sections were harvested, resulting in between 400 and 700 data points per experiment and year. In a second set of experiments, from 2002-2004, the interactive effects of N-availability in the soil, climatic conditions and late blight were studied in the presence and absence of copper...

Autores: Schmidt, Jan Henrik; Bleher, K.; Hallmann, Johannes; Finckh, Maria R.
Pflanzenparasitäre Nematoden (PPN) können im ökologischen Landbau zu erheblichen Ertragseinbußen führen. Die langen Fruchtfolgen und zumeist stärkere Unkrautvorkommen führen im Allgemeinen zu einem häufigeren Auftreten von PPN mit einem breiten Wirtsspektrum. Meloidogyne spp. und Pratylenchus spp. zählen zu den wirtschaftlich bedeutendsten Gattungen. Ihr endoparasitisches Verhalten bewirkt, dass bereits eine geringe Anzahl dieser PPN zu Schäden an Kulturpflanzen führen kann.

Einfluss von Sorte und gesteigerter Rottemistdüngung auf Ertrag und Qualität von mittelfrühen Speisekartoffeln
Provedor de dados: 21
Autores: Neuhoff, Daniel; Schulz, Dirk Gerhard; Köpke, Ulrich.
Während für den Verbraucher organisch angebauter Kartoffeln der Geschmack, die Koch-eigenschaften und der Gesundheitswert maßgebliche Kaufkriterien darstellen, sind für den Anbauer das Ertragsniveau, die Ertragssicherheit und die Lagereignung wichtige Zielgrößen.  Maßgebliche Einflußfaktoren auf diese Zielgrößen stellen die Sortenwahl und die Höhe der organischen Düngung dar. Im Rahmen eines von der Deutschen Forschungsgemeinschaft und der Eden-Stiftung finanzierten Projektes, an dem mehrere Institute der Universität Bonn beteiligt sind, werden an verschiedenen Standorten Feldversuche mit differenzierter Sortenwahl, Düngungshöhe und Düngungsart (mineralisch, organisch, biologisch-dynamisch) durchgeführt. Auf Grundlage der mit diesen Feldversuchen...

Autores: Schulte Geldermann, Elmar; Dlugowski, Susanne; Finckh, Maria R.; Bruns, Christian.
Three potato varieties – Nicola, Rosella, and Simone, differing in the time of initiation of tuber formation (early, middle, late, respectively) – were grown in a 3-factorial field trial for two years in 2 rotational positions i. e. after grass clover and winter wheat in order to induce a different fertility status. A copper control was included. Nitrogen supply after grass clover was between 26 to 32 kg higher than after winter wheat. Late blight severity was high in 2002 but almost nil in 2003 (Area under the curve 1100 versus 75, respectively). In both years, it was consistently but not significantly higher after grass clover. N-mineralisation rates in 2002 were below average due to unfavourable weather conditions in May and June. Thus, only in 2003 the...

Einfluss von Standort und Sorte auf Ertrag, Sortierung und Qualität von ökologisch erzeugten Kartoffeln für die Verarbeitung zu Pommes frites
Provedor de dados: 21
Autores: Krause, Tanja; Haase, Thorsten; Böhm, Herwart; Heß, Jürgen; Loges, Ralf; Haase, Norbert U.
Im Zuge der Ausweitung des ökologischen Landbaus müssen den ökologisch wirtschaftenden Betrieben neue Vermarktungswege geboten werden. Da die Nachfrage nach Convenience-Produkten stetig steigt, könnte die Erzeugung von Verarbeitungskartoffeln den Landwirten neue Einkommensquellen eröffnen. Sowohl das Sortenspektrum wie auch die Qualitätseigenschaften der Kartoffeln, die zur Weiterverarbeitung zu Pommes frites genutzt werden, unterscheiden sich erheblich von denen der Speisekartoffeln. Im Jahr 2003 wurden Sortenversuche an 3 Standorten mit unterschiedlicher Bodengüte (Wulksfelde, Lindhof, Frankenhausen)angelegt, die in 2004 fortgeführt werden, um eine fundierte Sortenbewertung in Abhängigkeit der Standorte hinsichtlich Ertrag und Qualitätsausprägung...

Autores: Jakob, Leitner; Juergen, Friedel; Andreas, Surböck; Gollner, Gabriele.
Der modifizierte Schälpflug oder "Stoppelhobel" schützt den Boden durch seine flach wendende Arbeitsweise, unterdrückt Beikräuter durch das ganzflächige Unterschneiden des Bodens, reduziert den Energieverbrauch und ermöglicht höhere Arbeitsgeschwindigkeiten. Im Jahr 2016/17 wurde auf einem Biobauernhof im Waldviertel im nördlichen Niederösterreich ein Praxis-Feldversuch durchgeführt. Zwei Bodenbearbeitungsverfahren vor dem Dinkelanbau - Var. A: 3x Stoppelhobel, Var. B: 2x Grubber / 1x Stoppelhobel - wurden hinsichtlich Bodeneigenschaften, Beikrautdruck und Ertragsmerkmalen untersucht. Es wurden keine signifikanten Unterschiede zwischen dem Dinkel-Kornertrag (Var. A 17,2 dt TM ha-1 / Var. B 18,3 dt TM ha-1), den pflanzenverfügbaren Nährstoffen im Boden,...

For decades the loss of biodiversity in cultivated landscapes has been extremely high. Now the question arises how to combine profitable farming practices with the conservation of species-rich grassland (SRG. The aim of the study was to analyse the relation between grassland biodiversity, cultivation method (organic or conventional),  cultivation intensity (low-input or intensive),  profitability and type of farms (beef or dairy  farm). For this study grassland biodiversity recordings of 12 organic and 12 conventional farms were analysed in a pairwise comparison. These results were then applied  to the economic factors of the farms. Significant differences in biodiversity were found within cultivations methods and type of farms. Organic farms had a higher...

Einfluss von Zwischenfrüchten auf Lachgasverluste und  Nitratauswaschung im ökologischen Marktfruchtbau in Abhängigkeit von der Vorfrucht
Provedor de dados: 21
Autores: Böldt, M.; Loges, Ralf; Kluss, Cristof; Taube, Friedhelm.
All-arable organic farming systems, especially when they are working without organic fertilizer, are often in challenge with their nutrient management to fulfill the requirements of crops. In this context one of the main issues is to mitigate nutrient losses. Here the use of catch crops may one strategy to counteract against this. We hypothesized that under the climate conditions of north-west Germany winter hard catch crops are more suitable to reduce nitrogen (N) losses than catch crops killed by frost, here especially with cereals or legumes as previous crop. In a field experiment in 2015/16 we tested 3 different catch crops (grown in pure stand and in mixture with legumes) after peas and triticale for their nitrogen loss paths over the winter period....

Im Feldversuchen wurde die Wirkung von Zwischenfruchtgemengen in Bezug auf das N-Bindungsvermögen des Aufwuchses, auf die N-Gehalte im Boden während der Winterperiode sowie den Ertrag und die Qualität nachfolgend angebauter Speisekartoffeln untersucht. Während unter den Zwischenfruchtparzellen nur eine vergleichsweise geringe Verlagerung des mineralischen Stickstoffs in tiefere Bodenschichten zu beobachten war, kam es in der Kontrollvariante zu teils deutlichen Verschiebungen. Die Variante ohne Zwischenfrüchte wies im dreijährigen Mittel den tendenziell niedrigsten Knollenertrag auf, während nach der Winterzwischenfrucht Landsberger Gemenge der signifikant höchste Ertrag gemessen wurde.

Einflüsse auf die Zusammensetzung wertgebender Inhaltsstoffe ökologisch erzeugter Futtererbsen (Pisum sativum L.)
Provedor de dados: 21
Autores: Witten, Stephanie; Böhm, Herwart; Aulrich, Karen.
Zu einer optimalen Rationsgestaltung gehört das Wissen über die Zusammensetzung bzw. die Gehalte an wertgebenden Inhaltsstoffen in den Einzelfuttermitteln. Im Ökologischen Landbau sind Abweichungen von konventionellen Analyseergebnissen sowie stärkere Schwankungen der Inhaltsstoffgehalte beschrieben (Böhm et al. 2007). Da zudem Zusatzstoffe aus verschiedenen Gründen nicht einsetzbar und, wie z. B. freie Aminosäuren, nicht zugelassen sind, ist eine Aufwertung der Ration sehr schwierig. Dadurch nimmt die Bedeutung der Kenntnis über die Inhaltstoffe der genutzten Einzelfuttermittel zu.  Vor allem die Versorgung mit Protein und essentiellen Aminosäuren, wie Lysin, Methionin und Cystein, spielt eine große Rolle und ist mit ökologisch erzeugten Futtermitteln nur...

Einflüsse der Rhizodeposition von Körnerleguminosen auf den Umsatz ihrer Residuen im Boden
Provedor de dados: 21
Autores: Mayer, Jochen; Buegger, Franz; Jensen, Erik Steen; Schloter, Michael; Heß, Jürgen.
Fazit:   Die Ergebnisse bestätigen die Bedeutung des NdfR* als ein wesentlicher Faktor für die N-Dynamik nach Körnerleguminosen. Der NdfR wird hauptsächlich als mikrobielle Residualmasse im Boden immobilisiert und bildet damit einen labilen Pool der organischen Bodensubstanz. Die Rhizodeposition von Körnerleguminosen beeinflusst, vermutlich über Interaktionen mit den Bodenmikroorganismen, den anschließenden Umsatz ihrer Residuen. Das Ausmaß dieser Wirkungen ist pflanzenartspezifisch und wahrscheinlich durch die Menge und Zusammensetzung der Rhizodeposition bestimmt. Zur Optimierung ökologischer Pflanzenbausysteme muss das Verständnis dieser Prozesse weiter vertieft werden.    * Nach der Ernte der oberirdischen Pflanzenteile zur Reife der Pflanzen wurden...

We compared field emergence and yield of a white- and a coloured-flowered variety of faba bean (Vicia faba) in relation to Bruchus rufimanus seed damage in a factorial, hand sown mini-plot field experiment. Further manipulating factors at sowing were, foot root rot inoculation with a 4-species Fusarium-mixture, a seed dressing with powdered testa material of the coloured-flower variety and sowing depth. In both varieties Fusarium-inoculation was the most detrimental and significant factor to field emergence and yield, interacting with a concordant B. rufimanus effect. Expectedly, the white-flowered variety was most affected. Tannin-containing testa meal did not reduce or compensate the impact of fungal inoculation and/or B. rufimanus. We hypothesize that...

From the year 2000 onwards, organic farmers in Eastern Austria have been  complaining about damages in arable crops by former inconspicuous or recently  immigrated insect pests. In our project, the recent obvious changes in occurrence of  arable pests were investigated with respect to climate change. The literature was  evaluated focussing on Austria and the adjacent Eastern Middle European countries.  Further on, conspicuously, weather-related pest outbreaks in Austria in the last years  were documented by interrogating plant protection experts. For a number of species  from cereals, root crops, oil-, protein- and fodder crops, in recent years an increasing  pest pressure was stated, caused rather by changes in cultivation systems (crop  rotation, reduced...

The growing economic importance of potatoes in organic agriculture has led to the intensification of potato production and farm specialization. This has in turn increased the occurrence of the Colorado potato beetle, the most important potato insect pest worldwide. The effects of the application of green manure mulch to potatoes, which  improves water and nutrient availability were investigated in a long-term field experiment, comparing two potato cultivation systems: conventional ploughing and hilling versus reduced tillage with dead mulch application. There were no differences in the initial degree of potato beetle infestation. However, a significant reduction in the  number of potato beetle larvae and eggs was observed. The mechanism behind the effects...

Autores: Junge, Stephan; Schmidt, Jan Henrik; Finkh, MR.
Reduced tillage enhances soil fertility and can help to avoid erosion. The drawback of increased weed pressure is a challenge for organic farmers due to the prohibition of  herbicides. Mulch could be a way to suppress weeds and to introduce reduced tillage systems in potato cultivation. The number of perennial weeds were monitored in a comparison of two potato cultivation systems: conventional ploughing and hilling versus reduced tillage with dead mulch. In 2014, perennial weeds in the mulch system increased to double the number compared to the ploughed system. The reverse  pattern was observed in 2015. This reversed effect was due to improved application methods of mulch with smaller particle size and a closer C/N-Ratio in the mulch in  2015 in...

Health is an increasingly important argument in advertising and in information given on  food product packages. The EU regulation on nutrition and health claims made on  food poses a challenge to such messages, including those on organic foods. This  paper examines whether organic foods with claims are refused or preferred, and  which are the influencing factors on choice for such a product. The results show that in  case that attentiveness to the claim is given, the likelihood of choice is significantly  higher. Several factors prove to be influencing choice significantly, but in different  directions. Recommendations for the marketing of organic products with claims are  derived from the results.

Autores: Plaßmann, Sabine; Hamm, Ulrich.
High prices and the price difference between organic and conventional food products are often considered to be the main barrier to an increased demand for organic prod-ucts. Based on a consumer survey, a structural equation model was estimated to identify factors influencing the willingness-to-pay for organic products. It was found that socio-demographic variables and individual price knowledge, price motivations and price attitudes of consumers are not sufficient enough to explain the willingness-to-pay for organic products. Strategies of product differentiation thus seem to be more promising for suppliers of organic food than focusing on consumer segments classified by sociodemographic and price-related aspects.

In organic agriculture site related factors of animal environment can’t be changed to a great extend by using remedies like additional food, concentrates and medicines as it is common in conventional agriculture. Therefore site related environment factors have a great influence on the possibilities of dairy cow breeding and husbandry on an organic farm. Non site related animal breeding can elevate the risk of (metabolic) stress and diseases in cows. The goal of this project was to introduce a new tool for advisers and farmers to estimate and ameliorate the site relatedness of dairy cow breeding and husbandry.

Over two years 6 groups (allocated by  weight and duration on pasture) were examined. In each group kids were randomly allocated to control- and trial-group. First additional feeding of the herbal mixture started 10 days before the beginning of pasture for 10 days. Once a month kids were weighed, eye color was controlled (FAMACHA) and fecal egg (EpG) count was examined. No differences were seen in body weight between control and trial groups.  Differences in FAMACHA and EpG were seen only in older animals. More kids in the control groups than in trial groups were dewormed according to FAMACH recommendations. Nevertheless, it...

Einsatz konventionell erzeugter Kosubstrate zur Biogasgewinnung im Öko-Landbau
Provedor de dados: 21
Autores: Siegmeier, Torsten; Möller, Detlev; Anspach, Victor.
This article determines type and amount of non-organic substrates used for biogas production on organic farms in Germany. Furthermore, it discusses determinants and problems of non-organic substrate use. Conventional substrate – mainly maize – is extensively used in larger biogas plants on farms without sufficient land area and/or low stocking rates per kWel. These overcapacities of organic biogas plants may represent maladjustment to external preconditions as a result of bad planning as well as carefully considered exploitations of business opportunities on the basis of external inputs. In order to reduce non-organic substrate use due to bad planning, on one hand biogas consulting services which account for the particular conditions of organic agriculture...

Der Anteil der Auslaufhaltungssysteme für Legehennen nimmt zu. Allerdings sind mobile Haltungssysteme noch nicht weit verbreitet. In Deutschland werden vor allem Mobilställe zweier Hersteller eingesetzt. Ein Hersteller setzt Folientunnel auf Stahlträgerkufen ein (Typ 1), der andere Ställe auf Rädern (Typ 2).  Ziel der Untersuchung war eine aktuelle Befragung der Mobilstallbetreiber(Typ 1: 110 Betriebe, Typ 2: 134 Betriebe) durchzuführen. 61 Fragebögen von Legehennenhaltern und 12 Fragebögen von Masthühnerhaltern wurden ausgewertet.  Betriebe mit Typ 1 hielten mehr Hühner und versetzten die Ställe weniger häufig. Die Hühner hatten im Vergleich zu Typ 2 weniger Auslauffläche. Betriebe mit Typ 2 erzielten höhere Eierpreise.

Autores: Jereb, Marina; Schwarz, Johannes; Weihrauch, Florian.
Ziel dieses von der BLE geförderten Projektes (FKZ 12NA014) ist es, durch Untersaaten in den Fahrgassen geeignete Überwinterungsquartiere zu schaffen, die es ermöglichen, eine konstante Population der Raubmilben über mehrere Vegetationsperioden hinweg zu etablieren. Im Hopfenbau ist eine nachhaltige Spinnmilbenkontrolle derzeit nicht möglich, da im Herbst die oberirdischen Pflanzenteile komplett abgeerntet und somit auch die potentiellen Überwinterungsstrukturen genommen werden. Aus diesem Grund wurden (1) Rohrschwingel Festuca arundinaceae, (2) Große Brennessel Urtica dioica und (3) Kleinblütiges Franzosenkraut Galinsoga parviflora ausgesät und auf ihre Eignung als Überwinterungsquartier getestet. Des Weiteren soll der Einsatz gezüchteter Raubmilben in...

Autores: Ertl, Paul; Knaus, Wilhelm.
Dairy cows are very efficient in converting fibrous forages into nutritious foods for humans. However, when fed potentially human-edible feeds, such as grains and pulses, dairy cows show very low efficiency in terms of net food production. In this debate, by-products are often mentioned as high quality feeds with reduced human-edible fractions for dairy cows. The aim of this feeding trial was therefore to evaluate the effect of a full substitution of a common concentrate mixture (COM) with a mixture including solely industrial by-products (BP) on milk production, feed intake, and the edible feed conversion ratio (eFCR) in organic dairy production. Cows receiving the BP mixture showed higher intakes of fibre fractions and ether extract, while starch intake...

The infestation of potatoes with wireworms is also in organic farms an increasing problem. The percentage of marketable potatoes is clearly reduced by the grub of wireworms. The grading is much more time-consuming and the produce is sometimes not saleable. In consequence the profitability of potato production is at risk. A monitoring of the occurrence of click beetles (Agriotes spp.) is possible with pheromone traps. First results of the year 2004 showed a very high occurrence of A. lineatus (2148 click beetles per trap) in clover grass (prec-crop to potatoes) on an organically managed farm in Northern Germany. The occurrence of A. obscurus was much lower with 257 click beetles per trap. The experiments should be continued over the next years in...

The interest in methods to proof organic food authenticity increases with the steadily rising popularity of food labelled organic. Profiling techniques enable the detection of a wide range of substances in biological samples. Together with bioinformatics tools these techniques are useful for biomarker searching, e. g. in plant extracts. Metabolomic and proteomic profiling techniques were used to screen organic and conventional wheat, originating from the DOK field trial in Switzerland. Up to 11 wheat varieties from three harvest years were analysed. We were able to detect a number of metabolites and proteins with significant differences between samples of conventional and organic grown wheat of the variety “Runal”.

Knapp hundert Jahre später wurde Quassia bzw. dessen Wirkstoff Quassin als Option zur Blattlausbekämpfung im Ökologischen Hopfenbau wiederentdeckt, da zu diesem Zeitpunkt insbesondere die zugelassenen Pyrethrine keine befriedigende Wirkung mehr zeigten. Im Rahmen mehrerer Versuche zur biologischen Wirksamkeit, die von 2002 bis 2006 über fünf Vegetationsperioden durchgeführt und dabei ständig wissenschaftlich begleitet wurden, erwies sich Quassin als effektiver Wirkstoff zur Blattlausbekämpfung bei ökologisch bewirtschafteten Aroma-Hopfensorten.

Einsatz von Saatwickenkörnern (Vicia sativa L.) in der Monogastrierfütterung: Masthühner
Provedor de dados: 21
Autores: Höhne, Anja; Bussemas, Ralf; Baldinger, Lisa.
Die Sicherung einer nachhaltigen und einheimischen Eiweißversorgung in der Monogastrierfütterung des Ökologischen Landbaus ist insbesondere im Hinblick auf eine Ausweitung der Produktion von großer Bedeutung. Körnerleguminosen dienen als Eiweißquelle in der Geflügelfütterung, und spielen als Stickstofffixierer eine wichtige Rolle in den Fruchtfolgen im Ökologischen Landbau. Da Saatwicken im Vergleich zu anderen Leguminosen geringe Standortansprüche aufweisen, ist eine Ausweitung ihrer Anbaufläche aus pflanzenbaulicher Sicht wünschenswert. Mit einem Rohprotein(XP)gehalt von um die 283 (206-393) g kg-1 T sind Saatwicken-körner zudem sehr eiweißreich, was sie für die Monogastrierfütterung attraktiv macht (Huang et al. 2017). Wie viele Körnerleguminosen...

Autores: Höhne, Anja; Bussemas, Ralf; Baldinger, Lisa.
Der Ausbau einer nachhaltigen und regionalen Eiweißversorgung in der Monogastrierfütterung des Ökologischen Landbaus ist insbesondere im Hinblick auf eine Ausweitung der Produktion von großer Bedeutung. Leguminosen bilden als Stickstofffixierer eine wichtige Säule der Bodenfruchtbarkeit im ökologischen Pflanzenbau, und fungieren als ebenso wichtige Eiweißkomponente in der Schweinefütterung. Da Saatwicken im Vergleich zu anderen Leguminosen geringe Standortansprüche aufweisen, sind sie eine mögliche Alternative zu den weitverbreiteten Ackerbohnen und Erbsen. Für die Schweinefütterung von Interesse ist der hohe Eiweißgehalt der Saatwickenkörner. Ein Nachteil von Körnerleguminosen wie der Saatwicke liegt jedoch darin, dass sie antinutritive Faktoren (ANF)...

Einsatz von Schwefel im ökologischen Weinbau - Chancen und Notwendigkeiten. Gibt es Alternativen?
Provedor de dados: 21
Autores: Hofmann, Uwe.
Die breite Wirkung des Schwefels (Stäubeschwefel, Netzschwefel) gegen unterschiedliche Schaderreger macht den weiteren Einsatz des Mittels sinnvoll und notendig. Beim Einsatz von Schwefel sind seine Nebenwirkungen (Raubmilbenbeeinflussung, Gär- und Geschmacksbeeinflussung) zu beachten.  Schwefel stellt neben Kupfer eines der wichtigsten Pflanzenschutzmitteln im ökologischen Weinbau dar. Die möglichen Alternativen auf der Basis von Pflanzenstärkungsmitteln müssen auf ihre Wirkung (Abhärtung, Induzierte Resistenz, Nahrungskonkurrenz) wie auch Nebenwirkungen weiter untersucht und ihre Formulierungen verbessert werden.

Einsatz von Strohmulch zur Unkrautregulierung bei Sojabohnen
Provedor de dados: 21
Autores: Froschmeir, S.; Reents, Hans Jürgen; Jobst, Florian; Urbatzka, Peer.
There is a problem with water erosion in organic growing of soybeans. A possible solution is growing under a mulch layer or cover crop. While this is usual practice in parts of the US, there is little success in Germany. A new approach is the use of straw material as a mulch to prevent erosion and suppress weed. The interrelation between weeds, soybean growth, yield and crude protein content was determined in a field experiment. There were significant differences in weed covering and weed species as well as in the yield between variants with straw mulch and without. The weed density  was highest in the variant without any treatment (21.0 % of surface) and lower in the variants with straw mulch (12.7 %). The highest yield was in the control variant (15.8...

In an interdisciplinary research project the following questions are to be examined:  1. How are the treatments common in practice (thermal, hydro-thermal and pressurethermal  treatment) to be rated in terms of the removal of anti-nutritive active factors  (ANF) in soy bean cake?  2. Which input of soy bean cake (treated) can be recommended for practical feeding in  organic broiler production?  Results and conclusion:  1. All treatments are sufficient for removal of ANF in soy bean cake.  2. For feeding mixtures in organic broiler production a content of 20 % (starter) or 15  % (finisher) soy bean cake can be recommended.

Einschätzung des Körpergewichtes bei Milchziegen
Provedor de dados: 21
Autores: Koopmann, Regine; Biedermann, Insa.
Die an der Rasse Bunte Deutsche Edelziege erhobenen Daten scheinen daraufhin zuweisen, dass für nichttragende oder frisch gedeckte Ziegen ein Rückschluss vom gemessenem Brustumfang auf das Körpergewicht zulässig ist. Die Regressionsgleichung lautet Körpergewicht (kg) = Maßbandwert (cm) x 1,445 - 70,24 mit R² = 0,71. Die Genauigkeit ist ausreichend für die Festlegung der Menge von Futterzusätzen oder Medikamenten. Die Regressionsgleichung sollte an großen Ziegenherden validiert oder korrigiert werden. Für das gezielte, selektive Entwurmen scheint die Methode nicht genau genug zu sein. Weitere Untersuchungen wären sehr wünschenswert. Ein „Einfach-BCS“ hat sich als ungeeignet für die Abschätzung des Körpergewichts erwiesen.

Surveys across different countries elicited that consumers had positive perceptions regarding organic wine production and reported a willingness to pay a premium for organic wine. But how do consumers behave in real purchase situations? Data obtained from a panel of 30.000 households was used to analyse German organic wine consumers´ buying behaviour. Households´ attitudes regarding sustainable  consumption were used for segmentation. The most promising consumer segment for organic wine from Germany is the cluster of consumers interested in organic and local  food. A quality strategy is advised. Regarding the cluster interested in organic food, a comprehensive sustainability approach is recommended which would be most effectively for German red wine...

An experiment was carried out to study the protein, fat and energy deposition profiles of male and female slow-growing broilers (ISA J-257) fed with organic diets. Feed mixtures with reduced dietary energy level and essential amino acids (EAAs) were tested. Birds were slaughtered at 0, 14, 28, 42 and 56 d of age. The whole body weight (WBW) was analyzed in each period to calculate the protein, fat and energy deposition. Gompertz growth curves were fitted to the data.   The diets did not affect the studied variables. After 28 d, males had higher WBW growth rates, and at 56 d higher energy and protein deposition rates than females, except for fat. According to the Gompertz curves, males reached higher maximum rates of WBW growth, energy, protein and fat...

For reasons of animal health, milk yield and for  environmental issues an optimal supply of protein and energy for dairy cows is essential. The aim of this study is to  examine potential protein and energy malnutrition and surplus in dairy herds. We present a comparison of the protein and energy supply between 18 conventional and  16 organic dairy herds. Initial results indicate an undersupply on energy in the first one hundred days of lactation in both the organic and conventional feeding regimes. It is easier to provide an adequate protein supply in conventional conditions in the first one hundred days than in organic ones. A balanced supply is guaranteed for a mere 21,3 % of the organic cows. In the second one hundred days this increases to 26,5 %,...

Djurhållning enligt KRAV:s regler ska främja djurens fysiologiska och etologiska behov. Alla djur ska hållas i en sådan miljö och skötas på ett sådant sätt att djurens hälsa och välfärd främjas. All KRAV-godkänd djurhållning ska kännetecknas av en mycket god djuromsorg och ett gott djurskydd. Dock finns en del problem med kycklingarnas hälsa och välfärd att åtgärda innan den ekologiska slaktkycklinguppfödningen till fullo  kan leva upp till detta.

Försök har anlagts på tre platser för att spegla olika förhållanden i södra och mellersta Sverige. Eftersom förhållandet mellan gräs och baljväxt förändras över tiden är det viktigt att studera uthålligheten i minst tre skördeår.

Orsaker till skillnader i produktion och beteenden i olika inhysningsformer för värphöns har till stor del en genetisk bakgrund. Generellt är bruna genotyper som ej näbbtrimmas mer benägna till fjäderplockning och hackning än vita leghornkorsningar. Olika genotyper visade sig från produktionssynpunkt reagera lika på förändringar i fodersammansättning, men olika från djurhälso- och beteendesynpunkt. Med de näringsmässigt strängare KRAV-regler som förespeglas träda i kraft 2001 krävs från djurskyddssynpunkt sannolikt andra genotyper, men kraven riskerar att bli högre ställda än vad som är biologiskt möjligt att uppfylla.

Ekologiskt korn som en utmaning - slutsatser av projektet "Växtvigör för ekologiskt korn"
Provedor de dados: 21
Autores: Väisänen, Jaana.
För att få höga kornskördar inom ekologisk odling skulle man utnyttja tidig sådd, biologiskt betat utsäde eller sjukdomståliga sorter. Bristen av betningsämnen och -metoder, som passar till ekologisk odling är en lika stor hinder för ökning av kornvikten och skördenivån som bristen av kväve. Skördar av ekologiskt korn kan dock höjas med flytgödsel eller urin, men de finns sällan tillgängliga för kornet. För att få högre halter av mineralkväve i jorden på våren, kan man som alternativ till gödselanvändning utnyttja sommarträdatekniken, där nedbrukning av förfruktsvallen börjar redan i Juli.

I lönsamhetsundersökningen finns för närvarande 34 nötdjursgårdar som för växtodlingens del är ekologiska producenter. Av dessa 34 gårdar är 16 mjölkproducenter. Mjölkproducenter som var för både åkrarnas och husdjurens del i programmet för ekologisk kontroll finns det endast 8 st. För växtodlingens del har ekologiska nötdjursgårdar jämfört med konventionella mjölkproducenter lönat sig ganska bra, detta mätt med lönsamhetskvot. Dock har det inte blivit företagarvinst i någondera av grupperna.  Gårdarna som utövar ekologisk produktion är i medeltal större än de i konventionell produktion. På nationell nivå är skillnaden ca....

Eksisterende og mulige nye kvalitetsmål ved dyrkning og handel med korn
Provedor de dados: 21
Autores: Jørgensen, Johannes Ravn.
Målet for landmanden er at få det største økonomiske afkast af sin produktion. Dette er ikke altid sammenfaldende med de kvalitetsmål, som modtageren af kornet opsætter, det være sig til maltbyg, brødhvede eller foder. Der er dog ved kontraktavl af f.eks. maltbyg og brødhvede mulighed for en merbetaling for at opfylde fastsatte kvalitetskrav. Derudover er det normalt en forudsætning at kvalitetskravene opfyldes for i det hele taget at kunne afsætte det producerede korn, medmindre der foretages en kvalitetsregulering, med mindre betaling for kornet som følge.

Zum Leben gehört Atmung, die immer auch Oxidation bedeutet. Zwar sind im menschlichen Körper zahlreiche Schutzmechanismen eingebaut, aber im Alterungsprozess nimmt deren Wirkung ab. Zusätzlich negativen Einfluss nehmen z.B.  Umweltgifte, ungesunder Lebensstil, Stress. Der P-Wert ist eine Faustzahl, die die Aktivität der Elektronen angibt, und wird aus den drei Parametern Redoxpotential, elektische Leitfähigkeit und pH-Wert errechnet. Je niedriger der zahlenmäßige Messwert, umso höher die Kraft der Elektronen, reduzierend zu wirken.  Woher kommt das Verfahren?  • entwickelt durch den Hydrologen Prof. L.C.

Two representative Hungarian soil-types (slightly humus sandy and loamy saline) were used to study the effect of various compost-products, made from sheep-yard manure and phosphorous amendments on the biomass-production of lettuce (Lactuca sativa var. Biweri) in a pot-experiment. Two types of phosphorous amendments, such as raw-phosphate with high- or a phosphorous rock with low solubility were used as amendments during the twelve-week composting process. Pots of five-hundred g weight were used and considering the ecophysiological demand of the lettuce, low (30 t/ha) optimum (60 t/ha) and provocative (120 t/ha) levels of manure compost were applied to the soils. Yield of lettuce and mineral content analysis were done by ICP and soil-analysis by TVG....

Elemental Contaminants in Fertilizers and Soil Amendments Used in Organic Production
Provedor de dados: 21
Autores: Baker, B.; Tracy, D.
Elemental contaminants in fertilizers pose a threat to human health and the environment. Organic agriculture can take measures to protect the public and the environment from the long-term effects of these contaminants, also known as heavy metals. Arsenic (As), cadmium (Cd), and lead (Pb) were identified as the top priority metals that need attention. Fertilizers and soil amendments used in organic production were randomly selected, and the laboratory results for the levels of As, Cd, and Pb compared against six different standards based on different models. Organic farmers are advised to avoid using fertilizers that may degrade the average levels found in soils in the United States. Standard-setting bodies are advised to prohibit the use of fertilizers and...

Elements of a European Action Plan for Organic Farming
Provedor de dados: 21
Autores: Dabbert, S.; Zanoli, R.; Lampkin, N.
The paper gives a number of reasons why a European action plan for organic farming is needed. The elements of a European action plan are outlined. A first step of an action plan is to find as much as possible a coherent description and understanding of the situation of organic farming in Europe at the outset and the barriers to further expansion. Strategic decisions that have to be taken carefully are identified: What weight should be given to organic farming policy? Why does policy want to support organic farming? Is organic farming just a system for less favoured regions? How important are the protectionist elements in organic farming policy? The answers to these questions are important to choosing an effective policy mix.  The paper argues that the...

Embedded energy in dairy stables
Provedor de dados: 21
Autores: Koesling, M.; Hansen, S.; Fystro, G.
The calculation of the embedded energy  (EE) of twenty barns shows that there is a considerable variation of EE per cow, where the lowest values were one fourth of the highest. Use of timber instead of concrete in walls had most effect to reduce the amount of EE. Cold barns can contribute to reduce the amount of EE, while the amount of EE is higher in free-stall than in tie-stall barns.  While for an existing building the amount of EE is nearly fixed, calculating the anticipated amount for a new building can help to reduce energy use in agriculture and thus contribute to a more sustainable pro¬duction. Incorporating EE in planning new buildings should be of special importance for organic farming, since regulations demand more area per animal than in...

Emission of Climate-Relevant Gases in Organic and Conventional Cropping Systems
Provedor de dados: 21
Autores: Kuestermann, B.; Huelsbergen, K.-J.
In 81 commercial farms in Germany, emissions of the greenhouse gases CO2, CH4 and N2O from crop production have been computed by model-based analyses. The considered influence factors comprise farm structure, mass and energy inputs as well as cultivation methods. A linear correlation was found between energy input and greenhouse gas potential. Due to lower N and energy inputs and also higher C sequestration as a result of humus restoration, the organic farms revealed area-related emissions (785 kg CO2 eq ha-1 a-1) that were 2.75 times lower than the emissions from conventional farms (2165 kg CO2 eq ha-1 a-1).

Organic farming systems provide multiple environmental benefits. Concerning climate change they have a substantial mitigation potential. Skinner et al. (2014) evaluated with Meta-Analysis the global dataset on comparative field measurements of soil greenhouse gas (GHG) fluxes under organic and non-organic agricultural management that have been published by the end of 2012. They showed that for arable land-use under organic management compared to non-organic 1) the cumulated area-scaled N2O emissions are about 15 % lower, 2) yield-scaled N2O emissions are slightly higher and 3) CH4 uptake is higher. However, this database is thin and further field measurements covering whole crop rotations are needed to close knowledge gaps. Therefore soil GHG fluxes are...

Organic agriculture is a holistic production system, which sustains the natural soil activity, ecosystem and people. This new system is an answer by organic producers to unsustainability of capital intensive agriculture, characterized by mass production, specialization, product standardization and high labour productivity that results in a weaker relation of agriculture to natural conditions and many negative consequences, especially in ecological, social and economic spheres. Development of organic production enabled development of the organic food market. Another incentive for organic food market development is consumers’ increased interest in nutrition, health and environment protection. The first segment of this paper will present an overview of...

En bekvem jord: hvad betyder det og hvordan opnås det
Provedor de dados: 21
Autores: Schjønning, P.; Munkholm, L.J.; Elmholt, S.
Ensidige sædskifter uden brug af husdyrgødning har vist sig at udpine jorden så meget, at der (bl.a.) bliver problemer med jordens evne til at smuldre under bearbejdning. Økologiske sædskifter vil oftest være så alsidige, at man dér vil opretholde en passende pulje af nydannet, ’aktivt’ organisk stof. Tildeling af husdyrgødning trækker i samme retning. Mekanisk påvirkning af jorden kan eliminere eller i hvert fald reducere de gode effekter af sædskiftet. Der er derfor al mulig grund til at begrænse skadelig pakning af overjorden mest muligt (brug brede lavtryksdæk) samt – om muligt – at undgå brugen af fræser og rotorharver.

Enacting New Nordic terroir as rootless American innovation or soiled European tradition?
Provedor de dados: 21
Autores: Ostrowski, Kasper.
The governing of food quality and food security is often intertwined with regional development and the notion of terroir pivotal - not least when considering cheese production. Terroir, however, is primarily understood in a strictly European sense, accentuating soil and tradition. Drawing on readings of ‘dairy produce strategies’ and deploying a possible world induced STS attitude, a crude model for differentiating American and European enactments of terroir is investigated in this paper. I claim that in the US, geographical claims are ‘uprooted’ and generally highlight alethic modalities – centerstaging individual competence and innovation. Geographical claims in EU, on the other hand, steers towards communal practices and deontic modalities grounded in...

Encouraging organic cultivation practices in Swiss allotment gardens
Provedor de dados: 21
Autores: Jahrl, Ingrid; Home, Robert.
Allotment gardens are usually managed by associations, with small allotment plots rented to individual tenant gardeners. Many garden associations have rules for organic production but the rules are neither followed nor policed. To find ways to motivate gardeners to manage their plots organically, we investigate the attitudes of Swiss gardeners towards organic gardening, and which motivations can be used to encourage and promote organic garden management. Interviews with 32 gardeners and other key informants from three Swiss target cities were analysed using content analysis. We found that organic practices are more likely when knowledge is held and that the social environment has a strong influence on behaviour, so potential exists for encouraging a...

Endoparasite infections and hygiene management in organic fattening herds
Provedor de dados: 21
Autores: Sundrum, Albert; Werner, Christina.
Introduction  Studies in different European countries have revealed that infections with endoparasites are one of the most important health problems in swine herds (Roepstorff et al., 1999; Eijck &amp; Borgsteede, 2005). In organic pig farming, the Regulation (EC) No 889/2008 includes several specifications which are expected to have severe impacts on parasite infection, i.e. straw bedding, access to outdoor run, addition of roughage to the daily feed ration and no prophylactic anthelmintic medication. Organic pig farms are also characterised by heterogeneous management practices and a lack in control measures (Ebke &amp; Sundrum, 2004; Werner et al., 2009) providing a non-assessable risk for helminth egg contamination in the environment. The aim of the...

Several studies have shown that changing from conventional to organic farming is an alternative to reduce negative impacts on the environment, for example nitrogen losses, reduced biodiversity and input of fossil energy per unit land and per unit product. In organic agriculture, as well, there is currently a trend towards specialized farming systems. To compensate for the lack of data on energy efficiency measured at farm scale, a comparison between three differently managed organic all-arable crop rotations and a typical rotation of typical regional N-intensive conventional farm was carried out over a two-year period at a highly productive site in northern Germany. Comparing the all-arable crop rotations, the organic systems had a 62 % lower output...

For the Hofpfisterei, one of biggest eco-bakery in Germany, the communication of the sustainable production of their bread plays an important role. The Hofpfisterei wants to introduce an environmental management over the supply chain, in order to improve among other things the energy efficiency. The potential is determined by a test net of organic farms by means of life cycle assessment. The reduction of energy input on the farms is to be judged as small. On the other hand the potential is high for energy output. The results show, that alone by the use of the clover grass in the market fruit farms, the energy outputs can be increased clearly. The goal of an energy autarky over supply chain can be achieved by this.

Autores: Klingebiel, Lars; Stülpnagel, R.; Graß, Rüdiger; Wachendorf, Michael.
In the research project ÖKOVERS different crops for fermentation were cultivated in a double cropping system at five locations in Germany. The crop yields after half a year and after one and half a year mixture of clover/grass were compared. The second crops were maize, sorghum, sunflowers, buckwheat and others, which have been fertilised with solid and liquid digestate. In one and half a year a yield over 20 t DM  ha-1 of clover/grass was realised. The yields of the second crops after a one and half a year clover/grass were clearly higher than after half a year clover/grass. The highest yield of the second crops in the mean of all locations was realised by maize with 11,5 t DM ha-1. The yield of sorghum and sunflowers and a mixture with maize and...

Energiepflanzenproduktion in biologischen Marktfruchtbetrieben
Provedor de dados: 21
Autores: Walla, DI Christoph; Schneeberger, Prof.Dr.DI Walter.
On organic crop farms mobile nitrogen sources are scarce. One possible source can be degassed biomass from fermented energy crops produced on organic farms. This study analyses the effects of an investment in a cooperative biogas plant on the production program and the net farm income using a linear planning model. The production of green electricity from biogas yields in a higher net farm income. Alfalfa grass is a more efficient energy crop than maize in organic farms. Fewer legumes and more cash crops are produced. The yearly labour requirement rises due to the production of energy crops, operation of the biogas plant and spreading the degassed biomass.

Energiforbrug i forskellige dyrkningssystemer
Provedor de dados: 21
Autores: Halberg, Niels; Refsgaard, Karen; Dalgaard, Tommy.
Energiforbruget i jordbrugsproduktionen er interessant både fra et ressource synspunkt og fordi udledningen af CO2 fra forbrænding af fossil energi bidrager til drivhuseffekten. Både i målsætningerne for den danske Landsforening for økologisk jordbrug (LØJ) og i landboorganisationernes oplæg til Godt landmandsskab år 2000 indgår desuden mål om at reducere forbruget af fossil energi og få den bedst mulige energiudnyttelse. Ved en kombination af studier i økologiske og konventionelle kvægbrug og brug af standardværdier for dieselforbrug til de enkelte markoperationer er der opstillet modeller for energiforbruget i mark og stald. I energiregnskaberne indgår både det direkte (diesel + el) og det indirekte energiforbrug (f.eks. energi medgået til produktion af...

Energy and emergy evaluation of potentials for energy self-sufficiency in Danish organic dairy farms by production of biogas and bioethanol
Provedor de dados: 21
Autores: Markussen, Mads Ville; Østergård, Hanne; Oleskowicz-Popiel, Piotr; Schmidt, Jens Ejby; Pugesgaard, Siri.
One obvious way to enhance agricultural resilience is for farms to increase self-sufficiency with necessities such as fuel, fodder and fertilizer. Our research seeks to uncover these potentials for Danish organic dairy farming.  The setting is a theoretical model of a farm-cooperation of 10 farms of 100 ha each producing only milk and animals for slaughtering and being self-sufficient with fodder and fertilizer. The question is if they can be self-sufficient with energy by means of shared biogas and/ or bioethanol production facilities. The method is mapping of energy, emergy (embodied energy measured in solar energy joules) and mass flows in different scenarios, that are based on empirical data from Danish dairy farms concerning mix of crops, crop yields,...

Energy and environmental burdens of organic and non-organic agriculture and horticulture
Provedor de dados: 21
Autores: Williams, A G; Audsley, E; Sandars, D L.
Production of 10 major commodities in England and Wales was studied using Life Cycle Analysis (LCA). Organic and non-organic (contemporary conventional) systems were compared. Organic production was generally less energy consuming, except for poultry meat, eggs and tomatoes. Environmental burdens, such as global warming potential or eutrophication were often greater per unit of production from organic than non-organic systems.

Energy balance of different organic biogas farming systems
Provedor de dados: 21
Autores: Helbig, S.; Küstermann, B.; Hülsbergen, K.-J.
The ecological impact of biogas plants depends on their integration into a given farming system. Therefore only farm-specific and no general statements are possible. In this paper, two different concepts of biogas production for an organic cash crop farm have been energetically balanced using a model software. The analysis of input and efficient use of fossil energy carriers provides information on the environmental relevance of the farm operations. Apart from this, renewable energy production in the farming systems is compared to food production, and changes in the farm output are described. It turns out that organically run cash crop farms can benefit from a reasonable integration of a biogas plant, both in food crop and energy production. An increased...

Energy efficiency of biomass production in managed versus natural temperate forest and grassland ecosystems
Provedor de dados: 21
Autores: Callesen, I.; Østergård, H.
In a conceptual model study based on literature data from Danish ecosystems, energy yield from biomass production was compared in two semi-natural ecosystems (broadleaved forest and grassland) and their managed counterparts. The highest net energy yield of harvested biomass was obtained in the managed grassland system. The energy efficiency in terms of output:input ratios were about 190:1 in the managed beech forest and 6:1 in the managed grassland. This is discussed in relation to nitrogen cycling, carbon storage and energy efficiency of biomass production.

Energy efficiency of fossil and renewable fuels
Provedor de dados: 21
Autores: Schäfer, Winfried.
Assessment results of renewable energy supply in agriculture and forestry are often questionable because 1. the methodology does not describe the nature dependent conditions of agricultural production, 2. there is no standard system boundary, 3. thermodynamic laws are violated and/or ignored, 4. direct and embodied energy is mixed, 5. the mainstream life cycle analysis (LCA) takes downstream and upstream inputs arbitrarily  into  consideration,  depending  on  the  research  objectives  and  the  research-funding  agency. Thus, the calculation results neglect a wide range of specific energy input figures of upstream and downstream factors outside farm level resulting in non-comparable figures.    The EROI describes the ratio between energy output and...

ENERGY EFFICIENCY OF SELECTED ORGANIC FARMS AND THEIR INFLUENCE ON GREENHOUSE GASES EMISSION
Provedor de dados: 21
Autores: Stalenga, Jarosław; Kuś, Jan; Madej, Andrzej.
Energy efficiency and greenhouse gas (methane and nitrous oxide) emissions were investigated in 2003 on 20 organic farms in the central part of Poland (Kujawsko-pomorskie voivodeship) using a questionnaire developed in the Institute of Soil Science and Plant Cultivation in Pulawy (Poland). Statistical data from the Central Statistical Office concerning the agriculture in the Kujawsko-pomorskie voivodeship was also used. A simple index (Ee) defined as a ratio of the total energy value of agricultural production (Pe) to the material and energy inputs (Ne) (in MJ) was used to evaluate the energy efficiency. The average value of this index was 2.05; however, it ranged from 0.04 to 16.59. In the organic farms, direct energy carriers (liquid and solid fuels and...

Energy use and Green house gas emission in organic agriculture
Provedor de dados: 21
Autores: Halberg, Niels.
Reduction of fossil energy use has a two-fold aim namely reducing the dependence of a limited, non-renewable resource and reduction of emissions of green house gasses (GHG). Consumers interested in reducing their carbon footprint from food consumption may consider whether a shift towards eating organic foods will do the job? This involves two questions: Is organic food more energy efficient and –given that one is dedicated to eating organic – which products and which producers results in a lower GHG emission. From a farmer perspective it is interesting to know how the carbon footprint of the production may be reduced. Over time the principles for organic agriculture has included specific references to the question of reducing the use of non-renewable...

Im Versuchsbetrieb Scheyern (Süddeutschland) wurde in Feldexperimenten die Energienutzungseffizienz (EUE) ökologischer Anbausysteme analysiert. Die EUE wurde für verschiedene Systemebenen - die Fruchtarten, die Fruchtfolge sowie Agroforstsysteme (AFS) bestimmt. Die Agroforstsysteme bestehen aus Baumreihen mit schnellwachsenden Gehölzen zur energetischen Nutzung sowie einer Fruchtfolge zur Nahrungserzeugung. Die EUE entspricht dem Verhältnis von Energieoutput zum Energieinput. Der Energieinput umfasst den Einsatz fossiler Energie, der Energieoutput den Brennwert der Ernteprodukte.   Die EUE von Weizen wird stark von der Vorfrucht beeinflusst; sie  beträgt nach Kartoffeln 10,1, nach Luzerne-Kleegras 19,5, im AFS 9,7 (nach Kartoffeln) und 18,8 (nach...

Energy use in crop production on danish mixed farms: Systems modelling of data from farm studies
Provedor de dados: 21
Autores: Halberg, Niels; Kristensen, Erik Steen; Refsgaard, Karen.
The problems of balancing agricultural production methods against environmental concern cannot be solved by focusing on single activities of livestock farming and experimental knowledge alone because of interactions between herds and crops and between the production system and the manager. An alternative method based on studies in private farms is proposed to evaluate the effects of the production intensity on pollution and resource efficiency. Energy use and crop yield in gram and grass-clover crops registered on conventional and organic mixed dairy farms were analyzed in order to facilitate modelization of energy efficiency in different production systems on different danish soil types. The energy efficiency was higher in organic crops on all soil types...

Energy use in organic farming
Provedor de dados: 21
Autores: Smith, L.G.; Williams, A.G.; Pearce, B.D.
Limited fossil fuel reserves, growing populations and rising input prices highlight the importance of increasing the efficiency of food production systems and reducing GHG emissions.  GHG emissions from fossil fuel use in agriculture are important along with the production of CH4 and N2O. In this context, organic agriculture has developed with an emphasis on resource use efficiency. The relative energy efficiencies of organic and non-organic farming were compared through a review of 50 studies including direct on-farm use and embedded energy in inputs.   Organic systems use less fossil-fuel energy on a unit of land area basis for nearly all crop and livestock types, although results are more variable per unit of product.  In many cases the difference can...

Engdriftsmåter og melkekvalitet
Provedor de dados: 21
Autores: Adler, Steffen A.; Steinshamn, Håvard.
Sammenhengen mellom engdriftssystemer og melkekvalitet i økologisk landbruk skal undersøkes i et nytt prosjekt. Valget mellom kortvarig og langvarig eng er avgjørende for den botaniske sammensetningen i drøvtyggerfôret og en kan forvente at melkas kvalitetsegenskaper påvirkes. Tolv økologiske melkebruk ble paret med 12 konvensjonelle i Midt-Norge og inngår i en toårig feltstudie som startet i januar 2007. Seks gårder i hver gruppe er valgt ut blant gårder med kortvarig eng og 6 blant gårder med langvarig eng. Annenhver måned skal det samles inn melkeprøver fra gårdstanken og fôrprøver på alle gårdene. Melkeprøvene vil bli analysert for fettsyresammensetning, oksidativ stabilitet, vitaminer, fytoøstrogener, sensorisk kvalitet og innhold av mikromineraler. I...

Enhanced catch-up growth after a challenge in animals on organic feed
Provedor de dados: 21
Autores: Huber, Machteld; Coulier, Leon; Wopereis, Suzan; Savelkoul, Huub; Nierop, Dré; Hoogenboom, Ron.
A feeding experiment was performed in two generations of three groups of chickens with different immune responsiveness. All groups were fed identically composed feeds from either organic or conventional production. In the young animals of the second generation an immune challenge was imposed. The chickens fed conventional feed showed overall a higher weight gain, whereas feed intake of the groups was similar. The animals on organic feed showed an enhanced immune reactivity, a stronger reaction to the immune challenge, as well as an enhanced ’catch-up-growth’ after the challenge.
