Auswirkungen unterschiedlicher Fruchtfolgen im ökologischen Landbau auf den Ertrag und die Produktivität
Provedor de dados: 21
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...

Provedor de dados: 21
Autores: Taramarcaz, Josy; Clerc, Maurice.
Der Versuchsbetrieb Mapraz wurde gegründet, um Fragen zu beantworten, wenn Betriebe auf viehlosen Bio-Ackerbau umstellen wollen. Nach zwölf Beobachtungsjahren, in denen in den sechs letzten Jahren zwei Fruchtfolgen verglichen wurden (mit einem Jahr oder zwei Jahren Kunstwiese - KW), sind die durchschnittlichen Erträge beim in Weizen um 8% tiefer als die Richtwerte oder vergleichbar mit den Bio-Richtwerten bei der Ackerbohne und beim Hafer. Die Deckungsbeiträge liegen zwischen CHF 250 und CHF 670/ha unter den Richtwerten der Bio-Landwirtschaft mit Vieh.  Die Fruchtfolge mit zwei Jahren KW zeigt einen besseren Deckungsbeitrag (CHF 200/ha) und benötigt weniger Arbeit (-2 Std./ha) als die Fruchtfolge mit einem Jahr KW. Die Ackerkratzdistel konnte mit der...

Conversion to Organic Production Software (OrgPlan, OF0159)
Provedor de dados: 21
Autores: Padel, Susanne.
This is the final report for Defra Project OF0159. The Organic Conversion Planner (OrgPlan) is a computer program for farmers and advisors reducing the time input necessary for planning a conversion to organic farming.   Conversion planning can help to identify whether organic management is suited to the farm and potential problems during the conversion period itself. This involves an assessment of the current situation of the farm, based on which proposals for an organic 'target (endpoint)' can be developed. This includes proposed rotation(s), cropping and stocking plan for the specific farm situation and the proposals need to be tested for their technical and financial feasibility, including impact on forage supply, nutrient requirements and financial...

Weed management in grain legumes using an intercropping approach
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Jensen, Erik Steen.
Grain legumes benefit the farming system via symbiotic N2 fixation and subsequent residue incorporation contributing to soil fertility together with their effect as break-crop in cereal rich rotations. However, grain legumes are weak competitors towards weeds and consequently weeds constitute a major problem. Since the European policies for reducing the negative effects of agricultural plant production on the environment point to reductions in pesticide use (Mortensen et al., 2000), there is a requirement to further develop strategies to reduce weeds. Intercropping involves the simultaneous growing of several plant species in the same field and the cropping strategy is known to involve interspecific interferences increasing the use of plant growth...

The effects of cropping systems on selenium and glucosinolate concentrations in vegetables
Provedor de dados: 21
Autores: Stavridou, Eleftheria.
Selenium (Se) and glucosinolates has been found to have beneficial effects for human health. The most common way to increase Se and glucosinolates in plants is through using inorganic fertilizers however, concerns over environmental contamination by fertilizers increased the demand for sustainable produced foods. Thus, the aim of this project was to evaluate the efficiency of different crop management strategies (catch crops, intercropping) to increase Se and glucosinolates concentrations in plants rather than the application of agrochemicals.    Catch crops have been used successfully to reduce sulphur and nitrogen leaching and increase nutrient availability for the succeeding, similar beneficial effects on Se may be expected. Nitrogen and sulphur...

Cotton-basil intercropping: effects on pests, yields and economical parameters in an organic field in Fayoum, Egypt
Provedor de dados: 21
Autores: Schader, Christian; Zaller, Johann G; Köpke, Ulrich.
In many countries, cotton is traditionally intercropped with other plants in order to increase yields and to control pests. We tested the effects of intercropping cotton (Gossypium barbadense L.) and basil (Ocimum basilicum L.) during one field season on pest infestation, yields, and economical parameters in the Governorate of Fayoum, Egypt. Basil, which is known for its repellent effect on various insect pests, was mixed with cotton in three different intercropping rates (no, medium and high basil area fraction) and two row distances (60 and 90 cm) using a substitutive design with four replicates. Compared with the non-intercropped plots, cotton-basil intercropping significantly reduced total pest infestation and led to a 50% reduced abundance of the pink...

Provedor de dados: 21
Autores: Madsen, K.H.; Bertelsen, I.; Askegaard, M.
Results from two years of field trial in organic spring barley showed a significantly higher grain yield per hectare in a competitive variety compared to a variety with lower competitive ability. Furthermore fertilizer placement resulted in a significantly higher grain yield than the broadcasted fertilizer application. The experiments furhermore, indicate, that combining fertilizer placement and growing a competitive spring barley variety will have mostly additive effect on the expected grain yield per hectare.

Autores: Moos, Jan Hendrik; Paulsen, Hans Marten; Rahmann, Gerold.
The abundance of weeds was monitored on several permanent plots on an organically managed farm in Schleswig-Holstein, Germany. Variation in weed abundance was observed between plots. Neither general increase, nor general decrease in weed abundance could be identified. Most of the annual variations within the data could be explained by annual variation in precipitation. A more intensive view was on the abundance of Cirsium arvense and Galium aparine agg., two problematic weed species. While the known problems arising from the appearance of C. arvense could not be reflected in the used data, the data revealed possible problems through the partly high abundances of G. aparine agg

Reduktion des Unkrautdruckes durch die Etablierung von Untersaaten in Mais-Bohnen-Gemengen
Provedor de dados: 21
Autores: Fischer, Jenny; Böhm, Herwart.
Am Thünen-Institut für Ökologischen Landbau (Schleswig-Holstein, sL, 740 mm, 8,7°C) werden von 2014-2016 Parzellenversuche zum Gemengeanbau von Mais mit Phaseolus-Bohnen durchgeführt. In vorangegangen Versuchen hat sich gezeigt, dass Mais und Bohnen infolge der langsamen Jugendentwicklung nur eine sehr geringe Konkurrenzkraft gegenüber Unkräutern aufweisen. Daher erfolgt die Aussaat der Bohnen erst nach Abschluss der mechanischen Unkrautbekämpfung mit Striegel und Hacke, zum 4-Blattstadium (BBCH 14) des Maises. Da mechanische Unkrautbekämpfungsmaßnahmen nach der Aussaat der Bohnen kaum durchgeführt werden können, wird in einem Untersaatenversuch geprüft, ob die Etablierung einer zusätzlichen Untersaat den Unkrautdruck im Gemenge nachhaltig reduzieren kann....

Competitive forbs in high-producing temporary grasslands with perennial ryegrass and red clover can increase plant diversity and herbage yield
Provedor de dados: 21
Autores: Dhamala, N.R.; Søegaard, K.; Eriksen, J.
European agriculture focuses on increasing biodiversity. However, in highly productive temporary grasslands in grass / arable systems, the biodiversity is usually low. Three non-leguminous species have shown high competitive strength in temporary grasslands and ample possibility to increase biodiversity without compromising yields. In this experiment, we examined in detail the competitiveness and productivity of the three forb species: chicory (Cichorium intybus), ribwort plantain (Plantago lanceolata) and caraway (Carum carvi) grown in different proportions in mixtures including traditional grassland species: perennial ryegrass (Lolium perenne) and red clover (Trifolium pratense), with fertiliser application as an additional factor.

Strip intercropping strategy for biomass to energy  production while on the same time maintaining soil fertility
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Jensen, Erik Steen; Carter, Mette S.; Johansen, Anders; Ambus, Per.
In contrast to energy technologies like solar and wind,  energy in the form of biomass can be stored and bioenergy produced when needed using a wide range of technologies. However, a substantial rise in the use of biomass for energy is expected, which means additional pressure on farmland sustainability. Organic agriculture (OA) is facing a big challenge producing bioenergy from local resources and on the same time maintaining soil fertility. There is a clear goal to reduce reliance on fossil fuels and thereby decrease greenhouse gas emissions, but the question is how to reach it? In a four year ICROFS (www.icrofs.org) project titled “BioConcens” (www.bioconcens.elr.dk/uk/) one objective is to design and test a strip intercropping concept.   Strip...

Åbent Hus: Forbedret udnyttelse af jord og ressourcer i økologiske dyrkningssystemer
Provedor de dados: 21
Autores: Kristensen, Helene.
Projektet SoilVeg handler om forbedret udnyttelse af jord og ressourcer i økologiske dyrkningssystemer for grøntsager med grønafgrøder. Der afprøves dyrkning af hvidkål i to nye dyrkningssystemer med reduceret jordbearbejdning. I det ene system plantes direkte ned i en tromlet vintergrønafgrøde uden anden jordbearbejdning, og her er det tanken at den tromlede biomasse dækker jorden og dermed holder ukrudt nede i løbet af sæsonen. I det andet system laves stribenedmuldning af grønafgrøden før plantning. De to nye systemer sammenlignes med almindelig nedmuldning og ingen forudgående grønafgrøde. Både vinterhestebønne, vinterært og vintervikke er blevet brugt som grønafgrøder og i blandinger med vinterrug. Disse forsøg kører ved Forskningscenter Årslev i 2016...

This work aims to evaluate the soil physical properties affected by cover crop rotation and soil management in a long-term experiment in southern Brazil. The experiment was established in 1986, with treatments combining six winter treatments and two tillage systems (conventional and no tillage). Bulk density, porosity, aggregate-size class distribution, and organic carbon content of the aggregates were determined at six depths. Bulk density was not affected by tillage systems and winter treatments. The soil disturbance by plowing enhanced the macroporosity, decreased the microporosity, and promoted the formation of smaller aggregate size, in comparison to no tillage. Apart from the soil management, all winter species increased the greater aggregate–size...

Comparison of interspecific competition and N use in pea–barley, faba bean–barley and lupin–barley intercrops grown at two temperate locations
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Hauggaard-Nielsen, Henrik; Joernsgaard, Bjarne; Jensen, Erik Steen.
Mixed intercropping of spring barley (Hordeum vulgare L.) with field pea (Pisum sativum L.), faba bean (Vicia faba var. minor L.) or narrow-leafed lupin (Lupinus angustifolius L.) was compared to sole cropping in two field experiments at different locations, on a sandy loam soil and a sandy soil, in Denmark in 2001.   Grain legumes were dominant in intercrops on the sandy loam soil, except for lupin, whereas barley was dominant in intercrops on the sandy soil site. Combined intercrop grain yields were comparable to grain yields of the respective sole cropped grain legume or sole cropped, fertilized barley on each soil site. On the sandy loam soil, pea-barley and faba bean-barley intercrops increased the proportion of plant N derived from N2 fixation in...

Growing systems for quality baking wheat: the effects of catch crops on yield and nitrate leaching
Provedor de dados: 21
Autores: Mauscherning, Inken; Loges, Ralf; Pedersen, Lene; Taube, Friedhelm.
In maritime climates the production of winter wheat often leads to high nitrate leaching losses. In this study mixtures of winter wheat and catch crops were analyzed as alternative growing system to avoid high leaching losses. In a field experiment pure winter wheat grown as control showed highest N-losses. Leaching losses of 140 kg N ha-1 after the pre-crop grass-clover and of 50 kg N ha-1 after oats as pre-crop were measured. Compared to this, growing winter wheat in mixture with forage rape or oats reduced nitrate leaching by 50 %. Common vetch as mixture partner to winter wheat had a lower potential to reduce leaching losses. Comparable results were obtained growing the catch crops alone followed by spring wheat. Due to the competition for growth...

Rates of photosynthesis and transpiration of spring wheat and barley as influenced by fodder precrops and their cropping period
Provedor de dados: 21
Autores: Küpper, Paul Martin; Perkons, Ute; Pries, Charlotte; Antar, Philipp Martin; Kautz, Timo; Köpke, Ulrich.
Perennial fodder cropping as compared to rotations including annual ploughing can increase the number of medium and large sized biopores in the subsoil. This can result in potentially facilitated root growth followed by increased accessibility of water in the subsoil. Additional plant-available water can enable stands to cope with dry periods in early summer, which will take place more often in future due to climate change. In this context we investigated whether crop species or cropping period of forage cropping influenced rates of photosynthesis and transpiration as indicators for water availability of spring wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.).

Wildlife and Biodiversity: integration and management of farming and wildlife for their mutual benefit
Provedor de dados: 21
Autores: Stocker, Phil; Hewlett, Kathleen; Brighton, Robbie.
This review summarises key research findings regarding the beneficial integration of wildlife and bio-diversity within organic farming.  In an ecological and agricultural context bio-diversity would ideally include the diversity of livestock breeds and crop species and varieties, their effect on wildlife habitats, and their role in supporting natural habitats and landscapes.  However this subject area is outside the scope of this review and although the presence of such diversity on organic farms will have impacted on the research findings studied, little specific research has been conducted.    The objective of this review is to provide information to advisors, based on peer reviewed research, to increase the scope and abundance of wildlife and...

Meta-Analysis on grain yield effects of cereal-legume intercropping. Second Year’s Training Report. June-August 2009
Provedor de dados: 21
Autores: Chastaing, Gaëlle.
In intercropping, more than one crop species are cultivated simultaneously on the same piece of land, to promote interaction between species. To determine the effects on yield performance of intercropping of legumes and cereals, a meta analysis has been set up based on data from publications on this kind of field trials as found from an extensive search on Web-of Science. The effect of intercropping has been  assessed by comparing yield in pure stand and in the intercrop of each species. Two measures were considered : i) The LER (Land Equivalent Ratio), which is a simple way to compare the pure yield with the intercropping yield by a sum of ratios and ii) the overall effect decomposed into sum of a ”selection effect” and a ”complementary effect” (Loreau...

Residual effects of cutting and grazing on grass/clover growth
Provedor de dados: 21
Autores: Eriksen, J.; Søegaard, K.; Askegaard, M.
The residual effect of cutting and grazing during the growing season was investigated in the spring and summer growth in an organic crop rotation with 1-4 year-old grass-clover mixtures of white clover (Trifolium repens L.) and perennial ryegrass (Lolium perenne L.) either with or without red clover (Trifolium pratense L.) and with and without slurry. The white clover mixtures had significantly higher yields in spring and summer in swards that were previously grazed compared to previously cut swards, when slurry was applied. The percentage of white clover in spring was considerably reduced by previous grazing and this caused the yield response of slurry application to be highest following grazing. A similar effect on the clover content was not found in the...

Nitrogen dynamics in temporary multi-species grasslands
Provedor de dados: 21
Autores: Dhamala, NR.
Plant diversity is often low in high-yielding temporary grasslands in Europe, with grass-clover being the traditional dominant mixture. Non-leguminous dicot forage herbs have potential as complementary species to traditional grassland species. Chicory (Cichorium intybus L.), ribwort plantain (Plantago lanceolata L.) and caraway (Carum carvi L.) are the three non-leguminous dicot forage herbs (hereafter called forbs) that have attracted most attention. Another form of grassland production of increasing interest is the practice of growing species mixtures containing only forage legumes for low-input production of biomass with high protein content. In this study, grassland nitrogen (N) dynamics were studied in a sward that included the forbs chicory, plantain...

Crop yield, root growth, and nutrient dynamics in a  conventional and three organic cropping systems with  different levels of external inputs and N re-cycling through fertility building crops
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian; Dresbøll, Dorte Bodin; Kristensen, Hanne L.
One core idea behind organic production is that cropping  systems should be less dependent on resource import than conventional production and minimize negative environmental effects. This study aimed to test novel organic rotations, designed to reduce reliance on external resource import. We compared a conventional system (C) and an organic system relying on manure import (O1) to two rotations (O2 and O3), both relying on autumn cover crops for soil fertility, and in O3 green manure rows were left as intercrops. Resource import differed between 149, 85, 25 and 25 kg N ha-1 year-1 in C, O1, O2 and O3.  Crop yields were lower in the organic systems (on average 82% of conventional yields), differing among crops, when based on the area grown with main crops....

Simulating Root Density Dynamics and Nitrogen Uptake – Can a Simple Approach be Sufficient?
Provedor de dados: 21
Autores: Pedersen, Anders.
The modeling of root growth in many plant–soil models is simple and with few possibilities to adapt simulated root proliferation and depth distribution to that actually found with different crop species. Here we propose a root model, developed to describe root growth, root density and nitrogen uptake. The model focuses on annual crops, and attempts to model root growth of different crop species and row crops and its significance for nitrogen uptake from different parts of the soil volume.

Improving green manure quality with phosphate rocks in Ontario Canada
Provedor de dados: 21
Autores: Arcand, M M; Lynch, D H; Voroney, R P; van Straaten, P.
Phosphate rock (PR) was applied to one conventional and two organic dairy fields and planted with buckwheat (Fagopyrum esculentum) as a green manure crop. In total, five types of PR were applied at three application rates in order to determine the yield, concentration of P in the aboveground tissue and the P uptake of buckwheat. It was found that PR of relatively high carbonate substitution and small particle diameter could increase buckwheat tissue concentrations to a quality such that mineralization of the buckwheat mulch could occur. Buckwheat mulch and residual PR increased soil P flux as determined by anion exchange membranes in situ in the following spring. This provides evidence that buckwheat of high P quality has the potential to supply P to a...

Land management aiming to sustain ecosystem services is an important issue, especially in biodiversity hot spots such as found in Mediterranean areas. In Mediterranean areas, viticulture is an important land use. Vineyards are frequently found on inherently poor soils and are submitted to intensive management practices, which threaten soil functioning and associated ecosystem services. To encourage winegrowers and stakeholders to be reflective and adapt their vineyard practices, we evaluated the effects of three soil management practices (inter row plant cover duration, weeding and fertilization strategies) on soil functioning in 146 commercial plots distributed in Southern France, by a complementary set of biological and physico-chemical indicators.

The preservation of soil and soil fertility are two major concerns in order to sustain food productivity. An increasing number of studies performed in conventional farming systems indicate that reduced soil tillage can increase the quality of agricultural soils. However, until now it is unclear whether reduced soil tillage can be used to develop sustainable organic farming systems. A long-term experiment was set up in 2009 at the research station Agroscope Reckenholz-Tänikon (ART) to compare conventional and organic farming systems with and without ploughing, and to assess the contribution of cover crops in reduced tillage systems. First results show that the cultivation of cover crops has a positive impact on weed suppression and yield of winter wheat and...

Autores: Känkänen, Hannu; Eriksson, Christian; Räkköläinen, Mauri; Vuorinen, Martti.
Cover crops can reduce leaching and erosion, introduce variability into crop rotations and fix nitrogen (N) for use by the main crops. In Finland, undersowing is a suitable method for establishing cover crops in cereals. The effect of annual undersowing on soil nitrate N was studied at two sites. Red clover (Trifolium pratense L.), white clover (Trifolium repens L.), a mixture of red clover and meadow fescue (Festuca pratensis Huds.), and westerwold ryegrass (Lolium multiflorum Lam. var. westerwoldicum) were undersown in spring cereals during six successive seasons, and a pure stand of cereal was grown in two years after that. In all years, the soil nitrate N was measured in late autumn, and in addition in different times of the season in last four years....

The aim of this study is to assess the weed suppressive ability of crop mixtures and impact of weeds on crop yield as a function of species and densities by means of field experiments and controlled experiments with mixtures of barley and pea, conducted in Sweden and Poland. The performance of crop mixtures was compared to the performance of pure crops with regard to their ability to suppress weeds. In the fields, natural weed populations were used while the controlled experiments employed Elytrigia repens or Sinapis alba as a model weed.     Preliminary results from the controlled experiment in Sweden showed that the presence of a crop (sole crop or intercrop) significantly diminished the growth of E. repens. The ability to compete was lower in peas,...

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.

Crop rotation limits Canada thistle, but not Couch grass or annual weeds
Provedor de dados: 21
Autores: Rasmussen, I.; Askegaard, M.
Direct weed control of annual as well as perennial weeds was necessary to reduce the amount of weeds in organic crop rotation experiments at three locations in Denmark. For Canada thistle, however, the rotation was the most important controlling factor: the rotation with grass-clover had less thistle biomass than the one without.

Autores: Silva, Edmilson Evangelista da; Azevedo, Pedro Henrique Sabadin; Almeida, Maxwell Merçon Tezolin Barros; De-Polli, Helvécio; Guerra, José Guilherme Marinho.
The objective of this work was to evaluate the influence of the intercropping and irrigation frequencies in the leaf development and productivity of taro (Colocasia esculenta) under organic management. The experiment was set up as a randomized complete block design, a factorial 2 x 2, with four replications. Taro was cultivated in monoculture or intercropped with Crotalaria juncea under two irrigation frequencies: every 3.5 days for 30 minutes and every 15 days for 2 hours. The intercropping increased taro petiole length but did not increase leaf area. The same effects were observed for irrigation frequency on the leaf area and petiole, length at the 30th and 60th days after C. juncea cutting. The amount of taro yield and offshoot number of class 1...

Improved weed management in organic crop production
Provedor de dados: 21
Autores: Melander, B.; Olesen, J.E.
Weed problems can constrain organic crop production resulting in significant losses in yield and quality. Especially perennial weed species such as Elytrigia repens, Cirsium arvense and Tussilago farfara are posing problems as arable cropping systems do not hamper their vegetative proliferation sufficiently. Annual weeds may also reach unacceptable infestation levels leaving the growers with poor yielding crops and severe future weed problems owing to the shedding and spread of weed seeds. Effective weed management is a key component for successful organic crop production and a prerequisite to increase the yielding potential of many organic crop production systems. Weed problems are most severe on stockless arable farms because the supply of nutrients can...

Organic Cover Cropping and Intercropping
Provedor de dados: 21
Autores: Bary, Andy.
This webinar is about Cover crops. They are an integral part of all organic cropping systems since they provide the foundation for organic nutrient management, pest control, weed suppression, and improving soil health. Andy Bary, Washington State University – Puyallup, explains the different classes of cover crops and the benefits each class provides. He also introduces the concept of “inter-seeding relay planting” or the growing of one crop planted between the rows of an existing crop, e.g. hairy vetch planted into corn. He discusses seeding techniques, species selection, and management strategies to ensure success. Weed suppression using summer cover crops is also discussed. The webinar is targeted both to newcomers and experienced organic farmers.

Nitrogen transfer from forage legumes to nine neighbouring plants in a multi-species grassland
Provedor de dados: 21
Autores: Pirhofer-Walzl, K.; Rasmussen , Jim; Høgh-Jensen, Henning; Eriksen, Jørgen; Soegaard, Karen; Rasmussen, Jesper.
Legumes play a crucial role in nitrogen supply to grass-legume mixtures for ruminant fodder. To quantify N transfer from legumes to neighbouring plants in multi-species grasslands we established a grass-legume-herb mixture on a loamy-sandy site in Denmark. White clover (Trifolium repens L.), red clover (Trifolium pratense L.) and lucerne (Medicago sativa L.) were leaflabelled with 15N enriched urea during one growing season. N transfer to grasses (Lolium perenne L. and xfestulolium), white clover, red clover, lucerne, birdsfoot trefoil (Lotus corniculatus L.), chicory (Cichorium intybus L.), plantain (Plantago lanceolata L.), salad burnet (Sanguisorba minor L.) and caraway (Carum carvi L.) was measured.

Hairy vetch cover crop affects weed diversity and composition in no-till sunflower
Provedor de dados: 21
Autores: Carlesi, Stefano; Antichi, Daniele; Sbrana, Massimo; Barberi, Paolo.
Vicia villosa Roth, or hairy vetch, is one of the most productive cover crops (CC) in Mediterranean dry areas, with an interesting potential as dead mulch in no-tillage cropping systems. In low-input cropping systems, mechanical termination of hairy vetch could replace a glyphosate application to control weeds. Mechanical termination (e.g. with a roller crimper) of hairy vetch is ineffective until the late growing stages of vetch, leading to delayed sowing and yield reduction in the following crop.  To find the best compromise in timing between effective termination of vetch and reasonable yield of no-till sunflower, an on-farm experiment was carried out in Pisa (Italy) in 2012/13 and 2013/14 to compare three termination techniques (roller crimper with no,...

N-Bedarf und N-Effizienz von Mischfruchtanbausystemen mit Ölpflanzen im ökologischen Landbau
Provedor de dados: 21
Autores: Paulsen, Hans Marten; Schochow, Martin; Behrendt, Andrea.
Mixed cropping systems with oil crops are of growing interest in organic farming. They can offer agricultural advances like competition against weeds, support against lodg¬ing and buffering of yield fluctuations. The aim of the cultivation method is to gain additional oil yields for energy or feed purposes. The reported higher land-efficiency-ratios of those mixed cropping systems should lead to higher nutrient requirements. But it is unknown if the different crops just compete for rare soil nutrients or if comple¬mentary effects in mixed cropping systems lead to higher nutrient efficiency. In a field study N-contents in plants and N uptake of diverse mixed cropping systems were compared to sole cropping systems. In linseed (Linum usitatissivum) or false...

Organic conversion strategies for stockless farming systems
Provedor de dados: 21
Autores: Huxham, Sally K; Sparkes, Debbie L; Wilson, Paul.
This report was presented at the UK Organic Research 2002 Conference. The identification of appropriate stockless organic conversion strategies will help farmers and growers in their decision to convert to organic production. The current practice of a two-year red clover/ryegrass ley conversion relies on subsidies to be economically viable. This standard conversion and six alternatives were tested on a sandy loam soil entering organic conversion. A test crop of winter wheat will be grown across the entire experimental area in the first fully organic year (2001/2002). Strategies containing a legume ley phase returned the greatest amount of nitrogen to the soil. At the end of the second year, pre-cultivation, there were no differences in soil mineral...

Inclusion of forage legumes in low-input grassland mixtures improves biomass production and soil fertility trough addition of nitrogen (N) from N2-fixation. The impacts of different mixture of legumes and companion grasses on the N production of the forage mixture have rarely been investigated under comparable soil and climatic conditions. We conducted a field experiment on a sandy soil at two nitrogen levels with seven two-species grassland mixtures: alfalfa (Medicago sativa), bird’s-foot trefoil (Lotus corniculatus), red clover (Trifolium pratense), or white clover (Trifolium repens) in mixture with perennial ryegrass (Lolium perenne), and white clover in mixture with meadow fescue (Festuca pratensis), timothy (Phleum pratense), or hybrid ryegrass...

Although the crop rotation is an essential element of organic farming, only few long-term trials exist which compare different crop rotations under temperate climate. 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...

Intercropping affects glucosinolate content in broccoli
Provedor de dados: 21
Autores: Stavridou, Eleftheria; Schreiner, Monika; Thorup-Kristensen, Kristian; Krumbein, Angelika.
Numerous studies proposed that the protective effect of cruciferous vegetables against cancer may be due to their relatively high content of sulfur-containing glucosinolates. Nitrogen (N) and sulfur (S) application significantly affect glucosi¬nolate concentration in plants. Total S requirement differs between crop species; in general S demand of Cruciferae is high. S supply has an impact on the total glucosinolate concentration but also on the relative proportions on the individual glucosinolates. Investigations showed that in broccoli plants, total glucosinolate concentrations were high at insufficient N supply, independent of the S level. This study aimed to improve the nutritional value of broccoli (Brassica oleracea var. italica) by intercropping. A...

Phosphat-Mobilisierung durch Haupt- und Zwischenfrüchte nach Düngung von weicherdigem Rohphosphat im ökologischen Landbau
Provedor de dados: 21
Im Ökologischen Landbau ist weicherdiges Rohphosphat als Phospatdüngemittel zugelassen. Die Effizienz von Rohphosphatdüngemitteln wird insbesondere durch den pH-Wert des Bodens sowie die Phosphat- und Ca-Konzentration der Bodenlösung beeinflusst. Zur Förderung und Stabilisierung der Bodenfruchtbarkeit werden die Böden gekalkt, so dass der pH-Wert mineralischer Böden meistens über 6 liegt. Kalkung dient nicht nur der pH-Wert-Stabilisierung, sondern durch die Zufuhr von Ca2+ wird auch die Bodenstruktur gefördert und stabilisiert. Darüber hinaus wirkt die Kalkung aber einer höheren chemischen Löslichkeit der Rohphosphate entgegen. Die daher auf mit Rohphosphat gedüngten Flächen (mit pH über 6) niedrigere Phosphatfreisetzung kann für die Phosphaternährung...

Möglichkeiten zur Verbesserung der Siliereigenschaften verschiedener perennierender Gras-/ Leguminosenmischungen durch Hoch-Zucker-Gräser
Provedor de dados: 21
Autores: Laser, H.; Leithold, G.
Herbage from legumes or legume-rich swards potentially has lower concentrations of water soluble carbohydrates (= wsc) and a higher buffering capacity (= bc) than grass grown in pure stands. The analysis of three forage legumes (= Trifolium repens, Tri-folium pratense and Lotus corniculatus) in monoculture and mixtures (= 50/50) with the grass species Festuca rubra demonstrates, that the ratio of wsc concentration to bc is critical low, especially when the herbage is harvested at physiological young stages to obtain a higher forage quality. This means an increased risk for silage mak-ing, especially at DM contents which are below 30%. New breedings of the grass spe-cies Lolium perenne with higher sugar contents offer a possibility to increase the wsc...

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.

Ecological Recycling Agriculture to Enhance Agro-Ecosystem Services in the Baltic Sea Region: Guidelines for Implementation
Provedor de dados: 21
Autores: Stein-Bachinger, Karin; Reckling, Moritz; Bachinger, Johann; Hufnagel, Johannes; Wijnand, Koker; Granstedt, Artur.
Eutrophication caused by agriculture is an increasing ecological threat to the Baltic Sea. Modern, resource-efficient farming systems based on integrated plant and animal production, effective nutrient recycling and low external inputs can enhance multiple agro-ecosystem  services, resulting in reduced pollution. Practical examples of such farming systems are not widespread.  Therefore, the Baltic  Ecological Recycling  Agriculture  and Society (BERAS) Implementation project aimed to foster this systemic shift. In this paper, agronomic strategies are described to improve nitrogen (N) efficiency for the conversion to ecological recycling agriculture (ERA). First, N farm gate balances of 22 farms in conversion are presented. They showed a large variation...

However in a system perspective attention should also be paid to others services such as break-crop effect, erosion protection, increasing biodiversity. It is discussed how intercropping can be seen as a cropping strategy worth considering to fullfill the demands mentioned above.

Field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L) were intercropped and sole cropped to compare the effects of crop diversity on the use of nitrogen sources in European organic crop-ping systems. Across a wide range of growing condi-tions pea-barley intercropping showed that nitrogen sources were used from 17 to 31% more efficiently by the intercrop than by the sole crops. Intercropping technologies offers the opportunity for organic cropping systems to utilize N complementarity between component crops, without compromising total crop N yield levels

Udbytte og økonomi i sædskifter – erfaringer fra sædskifteforsøgene
Provedor de dados: 21
Autores: Tersbøl, Michael.
Udbyttet i de forskellige sædskifter afhænger mest af jordtype og gødskning. Kløvergræs som grøngødning øger udbyttet i vinterhvede, dog ikke på grovsandet jord. Sædskifter med og uden grøngødning er økonomisk ligeværdige, når omkostninger til maskiner og arbejde tages i betragtning. Helårsgrøngødning er særlig relevant for at forebygge problemer med rodukrudt.

Anaerobic co-digestion of grass and forbs – Influence of cattle manure or grass based inoculum
Provedor de dados: 21
Autores: Cong, W.-F.; Moset, V.; Feng, L.; Møller, H.B.; Eriksen, J.
Anaerobic co-digestion of agricultural by-products or wastes with complementarity characteristics is commonly used to enhance methane yield. This study firstly explores the possibility of co-digesting grass and forb species (white clover, chicory and plantain) differing in nutrient composition in enhancing methane yield. This was examined with two inocula (a cattle manure-based inoculum and a grass-based inoculum) in a batch assay. Results showed that co-digesting grass and forbs synergistically enhanced methane yield potential on average by 31 L kg−1 volatile solids (+11%) and reduced lag phase time by 0.8 day in the grass-based inoculum, but not in the cattle manure-based inoculum. Mixtures containing plantain showed more consistent synergistic effect...

Efterafgrøder efter kløvergræs før vårhvede
Provedor de dados: 21
Autores: Rasmussen, Henrik.
En kløvergræsmark indeholder store mængder forholdsvis let omsætteligt kvælstof. Det giver selvfølgelig en god eftervirkning med højt udbyttepotentiale i den efterfølgende afgrøde. Men det giver også stor risiko udvaskning af kvælstof, når en kløvergræsmark pløjes. Udvaskning af kvælstof bør undgås af hensyn til grundvandet, men også af hensyn til den tilgængelige kvælstofmængde på bedriften. Kvælstof, der forsvinder ud af rodzonen, er ikke længere tilgængeligt for afgrøderne!

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....

Stepwise incorporation of white clover (Trifolium repens L.)as fertiliser increases nitrogen fixation and improves nitrogen retention when intercropped with leek (Allium porrum L.)
Provedor de dados: 21
Autores: Xie, Yue; Sørensen, Jørn Nygaard; Petersen, Karen Koefoed; Kristensen, Hanne Lakkenborg.
Background and aims  We investigated whether the incorporation of intercropped white clover as a split-dose fertiliser improves N retention of the plant-soil system in leek production.    Methods  White clover and leek were grown in pots where clover was stepwise incorporated into soil as fertiliser. Half of the clover was incorporated before leek transplantation (LT), the other half was incorporated 26 (S1) or 41 (S2) days after LT, compared with full incorporation of all clover (F) before LT. 15N injection and leaching studies were performed to investigate interspecific competition and the effects of precipitation on soil N availability.    Results  Stepwise incorporations increased or had no effect on leek growth, despite competition for N between white...

Competitive ability of grain legume-barley intercrops towards volunteer crops and weeds
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Tranberg Nikolajsen, Jacob; Steen Jensen, Erik.
Field pea (Pisum sativum L.) and blue lupin (Lupinus angustifolius L.) were either sole cropped or inter-cropped with barley (Hordeum vulgare L.) at two levels of nitrogen application to determine the effects of interspecific interaction in an intercrop and nitro-gen fertility on competitive ability towards volunteer crops - exemplified by red clover (Trifolium pratense). The dynamically change of competitive ability by intercropped species over time was shown to be im-portant in order to reduce opportunities for growth of volunteer crops and weeds

Searching the critical soil organic carbon threshold for satisfactory tilth conditions – test of the Dexter clay:carbon hypothesis
Provedor de dados: 21
Autores: Schjønning, P.; de Jonge, L.W.; Moldrup, P.; Christensen, B.T.; Olesen, J.E.
The concern for deteriorating soil structure at low soil organic matter (SOM) contents calls for better knowledge of SOM interaction with soil minerals as well as guidelines for soil conservation. We measured clay dispersibility in a field with a textural gradient. Our results support the concept of differentiating soil content of clay in a complexed and non-complexed part although our data did not point out an exact clay/OC ratio threshold. Our results also indicated that labile fractions of SOM may play an important role in soil physical behavior. We revisited literature data and found evidence that soil content of fines (&lt;2 or &lt;20 μm) is a major determinant of soil specific surface area (SA). We noted that soil SA coverage with SOM changed...

Intercropping grain peas with barley
Provedor de dados: 21
Autores: Alföldi, Thomas; Clerc, Maurice; Stöcklin, Milo.
Intercropping of legumes with cereals is a promising possibility to produce fodder protein while creating few costs and using few resources.    Practicable cultivation methods of intercropping with protein peas/barley and field beans/oats were developed, both with mixing ratios of 80% and 40%, respectively, of the usual local seeding amount for the single crop (possible for winter crops as well as for spring crops).     The grain serves as a support crop, suppresses weeds and provides a risk coverage in years of poor grain legume development.    Since 2010, the acreage of organic peas and beans, mostly grown in mixed cultures, has multiplied.     This increase was also possible due to mills that buy and separate the yield of intercropping systems into its...

Modelling crop rotations of organic farms
Provedor de dados: 21
Autores: Bachinger, J.; Zander, P.
With the described holistic model approach it is possible to generate agronomically-suitable and detailed 3-8 year crop rotations for diluvial sites in north-eastern Germany under the special demands of organic farming systems with and without livestock production. The stand-alone version can be used for crop rotation planning at the farm level. In addition, this model version may be applied for studying the influence of the parameter and estimation algorithm ranges within the model on the complex interactions between site condition, cropping methods and the rotational cropping systems. Sensitivity analyses show those model parameters and estimation algorithms which have to be managed with special care and those for which further research is needed.

The amount of internationally published evidence on the effects of grain legumes on nitrate leaching is sparse and some studies may have weak points. Nevertheless, this mini-review indicates that the level of N leaching is 0–20 kg N ha-1 greater after pea than after cereals. Methods to prevent N leaching should be further developed and there is a need to genetically improve the root systems of grain legumes.

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.

Management of forb species mixtures for high biomass production
Provedor de dados: 21
Autores: Mortensen, T.; Eriksen, J.; Søegaard, K.
Including forb species in grassland mixtures may secure a more biodiversity-friendly production of biomass. This experiment showed interesting future perspectives in terms of production of low-cost biomass for e.g. biogas production, which can be obtained by reducing the number of cuttings without compromising yield levels. No significant differences in dry matter (DM) yields of chicory, birdsfoot trefoil, yarrow and a 13 species mixture were observed between the situations with four compared to one autumn cut per year. Especially the 13 species mixture showed great potential in terms of yield and suppression of unsown species, for which reasons it should be developed further through knowledge on the species in pure stands.

Von den indirekten Maßnahmen zur Unkrautbekämpfung bzw. –unterdrückung bildet die Fruchtfolge den wichtigsten Einzelfaktor. Ihre Wirkung auf die Zurückdrängung der Unkräuter ist beim jährlichen Wechsel von Blatt- und Halmfrüchten am stärksten.     Die Grundbodenbearbeitung, die wendend oder nichtwendend erfolgen kann, hat einen erheblichen Einfluss auf die Verunkrautung. Nach unkrautarmen Blattfrüchten kann durch eine nichtwendende Bodenbearbeitung der Unkrautauflauf bis um 50 % vermindert werden, während in getreidebetonten Fruchtfolgen durch den Pflugverzicht Apera spicaventi, Alopecurus myosuroides und Bromus-Arten zunehmen.

The use of mixed species cropping to manage pests and diseases – theory and practice
Provedor de dados: 21
Autores: Ramert, Birgitta; Lennartsson, Margi; Davies, Gareth.
This paper was presented at the UK organic research 2002 on behalf of colloquium of Organic Researchers (COR). Mixed species cropping is often perceived as a viable tool to increase on-farm biodiversity in organic agriculture and is a potentially important component of any sustainable cropping system. Apart from increasing total farm productivity, mixed species cropping can bring many important benefits such as improvement of soil fertility management and suppression of pests and/or diseases. In this sense it can be seen as performing different eco-services in the farm system. This paper discusses mixed cropping in this context while focusing on its potential and actual use as a tool to manage pests and diseases in organic farming systems.

Am Beispiel der Reduzierung von Bodenerosion konnte modellhaft gezeigt werden, dass die Integration von Umweltzielen für einen integrierten Betrieb mit geringeren Opportunitätskosten verbunden ist, als dies bei dem ökologisch wirtschaftenden Betrieb der Fall ist. Aufgrund der Notwendigkeit einer vielfältigen Fruchtfolge mit Zwischenfrüchten bzw. Untersaaten im ökologischen Landbau, ist das Erosionsrisiko im ökologisch wirtschaftenden Betrieb bereits ohne Auflagen deutlich niedriger, als die im integrierten Betrieb. Ein integrierter Betrieb ist in der Regel nur durch Zahlung von Prämien zu einer Berücksichtigung von Umweltzielen bereit.

In crop rotation green manures as winter cover crops enhance ecosystem services of farming
Provedor de dados: 21
Autores: Talgre, Liina; Tein, Berit; Eremeev, Viacheslav; Matt, Darja; Reintam, Endla; Sanches De Cima, Diego; Luik, Anne.
Organic farming systems should be characterized by excellent soil fertility management to keep plant nutrient cycles short and as closed as possible.  Therefore, it is extremely important to establish growing systems that have rotations with appropriate crops and intercrops to ensure fertile and biologically active soils, to enhance biodiversity and to provide high quality crop yields. Locally available organic  fertilizers include green manures and animal manure. The influence of green manures as intercrops and these combined with composted cattle manure on soil properties, biodiversity indicators and crop yields was studied in a crop rotation experiment in three organic systems at the Estonian University of Life Sciences.

Impact of cropping system on mycorrhiza
Provedor de dados: 21
Autores: Kahiluoto, H.; Vestberg, M.
The impact of cropping system on field communities of mycorrhizal fungi was studied utilising a long-term experiment on a loamy soil. Two contrasting crop rotations each with two fertilisation regimes were compared. The conventional crop rotation (barley-barley-rye-oat-potato-oat) was fertilised at either full or half the normal recommended rate. In the low-input crop rotation, one year with barley was replaced by clover, and oat was cultivated in mixture with pea. For this rotation biotite and raw phosphate was used to compensate for the K and P of the harvested yield; animal manure was used at the beginning only. Clover and straw were returned to the soil either directly or after composting. Mycorrhizal infectivity and effectiveness were studied in...

Simulating Root Density Dynamics and Nitrogen Uptake -Field Trials and Root Model Approach in Denmark
Provedor de dados: 21
Autores: Pedersen, Anders; Zhang, Kefeng; Jensen, Lars Stoumann; Thorup-Kristensen, Kristian.
Plant soil and atmosphere models are commonly used to predict crop yield and associated environmental consequences. Such models often include complex modelling of water movement, soil organic matter turnover and above ground plant growth. However, the root modelling in these models is often very simple, partly due to a limited access to experimental data. Here we propose a root model developed to describe root growth, root density and nitrogen uptake. The model focuses on annual crops, and attempts to model root growth of different crop species and row crops and its significance for nitrogen uptake from different parts of the soil volume.

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.

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 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.

Long-term organic crop rotation experiments for cereal production – yield development and dynamics
Provedor de dados: 21
Autores: Askegaard, Margrethe; Olesen, Jørgen E.; Rasmussen, Ilse A.
A crop rotation experiment was established in 1996/97 at three locations representing different soil types and climates. Three factors were tested: i) crop rotation with different proportions of N2-fixing crops, ii) with and without a catch crop, and iii) with and without animal manure. A green manure crop increased yields in the following cereal crops, but at the rotational level, total yields were larger in crop rotations without a green manure crop. There were positive effects of animal manure and catch crops on yield. However, except for the coarse sandy soil, the yield effects of catch crops and animal manure decreased over time when a grass-clover green manure was included in the rotation. It appeared that the buffering effect of clover can...

Energy crops for biogas production need to be integrated into sustainable and site  adapted crop rotation systems, minimising the competition with food production.  Luzerne/clover (-grass), sun flower, maize, green-rye + maize and vetch-rye + maize  were compared at two sites in Austria with semi-arid (Raasdorf) and humid (Lambach)  conditions with and without biogas slurry application. The yield of legumes and  fertilised non-legumes at the humid site were 9 % to 56 % higher then at the semi-arid  site. The 2-crop system maize following vetch-rye achieved the highest yields at both  sites. Slurry from the biogas plant increased the yield only at the humid site.

The effect of nitrogen (N) supply and weeds on grain yield of spring barley, winter wheat and winter rye was investigated from 1997 to 2004 in an organic farming crop rotation experiment in Denmark on three soil types varying from coarse sand to sandy loam. Two experimental factors were included in the experiment in a factorial design: 1) catch crop (with and without), and 2) manure (with and without). The apparent recovery efficiency of N in grains (nitrogen use efficiency, NUE) from NH4-N in applied manure varied from 29 to 38% in spring barley and from 23 to 44% in winter cereals. The NUE of above-ground N in catch crops sampled in November prior to the spring barley varied from 16 to 52%, with the highest value on the coarse sandy soil and the lowest...

Intercropping and sustainability
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Kinane, Julie; Trydeman Knudsen, Marie; Jensen, Erik Steen.
Grain legume-cereal intercropping is a method to obtain greater and more stable crop yields, improve the plant resource utilisation (water, light, nutrients), increase the input of leguminous symbiotic nitrogen fixation (SNF) to the cropping system and reduce negative impacts on the environment. However, due to agricultural intensification of plant breeding, mechanisation, and fertiliser and pesticide use over the last 50 years, intercropping has disappeared from many European farming systems.    Motivations for reintroducing grain-legume-cereal intercropping relate to the problems faced by intensive farming systems. During the 1980s it became evident that West European agricultural production systems (often characterised by monocultures, nutrient...

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...

Yield and quality of organic versus conventional potato crop
Provedor de dados: 21
Autores: Mourão, Dr. Isabel; Brito, Dr. L Miguel; Coutinho, Dr. João.
The improvement of organic fertilization practices is essential to increase organic potato production in the highland region of NW Portugal, with environmental benefits and better returns. For that reason, the response of organic potato was evaluated throughout a randomized block design experiment, with two cultivars (Raja and Virgo) and increasing rates of composted organic pig manure (0, 15, 30 and 45 t ha-1). These cultivars were also grown with mineral N fertilizer (120 kg N ha-1) under conventional practices to compare the results between crop systems, 30, 45, 60, 80 and 125 days after planting.  Crop yield was not improved with increasing rates of compost application because the N mineralization rate of the compost was small and soil organic matter...

Nitrous oxide emissions from organic farming: the importance of well-timed ley cultivation
Provedor de dados: 21
Autores: Ball, B C.
The period after ploughing of grass-clover within a ley-arable rotation is when nitrogen accumulated during ley cropping is most vulnerable to loss. I investigated how date of ploughing and date of cessation of grazing before ploughing influenced losses of nitrogen as nitrous oxide during establishment of the first cereal crop. Crop nitrogen uptake was also assessed. Nitrous oxide (N2O) emissions in the 1-2 month period after autumn or spring ploughing or after sowing were typically between 20 and 150 g N ha-1 day-1 and increased with temperature and rainfall. Tillage and sowing operations on previously ploughed soil stimulated N2O emissions even several months after ploughing. Cumulative N2O emissions were highest (~8 kg ha-1 over 17 months) after late...

Species interactions between forbs and grass-clover contribute to yield gains and weed suppression in forage grassland mixtures
Provedor de dados: 21
Autores: Cong, W.-F.; Suter, M.; Lüscher, A.; Eriksen, J.
Grass-legume mixtures characterized by high productivity, efficient nitrogen (N) use and strong weed suppression were proposed to increase sustainability of grassland production. Adding competitive forbs to grassclover mixtures can be expected to further enhance the high productivity of grass-clover mixtures. This study investigates whether and to what extent adding forbs to a grass-clover mixture results in yield gains, and estimates the contributions of forb species (identity effect) and interactions with the grass-clover mixture (diversity effect) to these gains. It further examines the effectiveness of weed suppression in forb-containing grass-clover mixtures. Fifteen pure and mixed stands, all comprising the grass Lolium perenne L. and the legume...

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.

Autores: Hallmann, Johannes; Schmidt, Jan Henrik; Finckh, Maria Renate.
Agriculture has transformed over the past centuries dramatically to become highly dependent on non-renewable fossil fuels, synthetic fertilizers and plant protection agents. This often occurs at the cost of soil degradation and soil food web disturbance. Future agriculture must not only be productive but also provide ecosystem services such as carbon sequestration, pest and disease suppression, nutrient cycling and water storage to become sustainable in the long-term. Sustainability is especially fostered by reduced tillage and the presence of a permanent layer of plant residues. Under such conditions, soil compaction is reduced, soil structure improved, water infiltration enhanced, soil organic content increased and microbial activity stimulated. However,...

Organic crop rotation experiments - short-term versus longer-term results
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Askegaard, Margrethe; Olesen, Jørgen E.
Danish experiments with cereal-based organic crop rotations have shown that the short-term results (the first course, up to four years after conversion) are different from those obtained in the longer-term (the second course, fifth to eighth year after conversion). Yield gain from use of manure increased from the first to the second course on a sandy soil, but decreased on loamier soils. Yield gain from leguminous catch crops increased from the first to the second course in a crop rotation without grass-clover. Some of these effects were caused by buffering effects of the grass-clover, other effects were caused by changes in soil fertility over time.

The amount of internationally published evidence on the effects of grain legumes on nitrate leaching is sparse and some studies may have weak points. Nevertheless, this mini-review indicates that the level of N leaching is 0–20 kg N ha-1 greater after pea than after cereals. Methods to prevent N leaching should be further developed and there is a need to genetically improve the root systems of grain legumes.

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.

N supply in stockless organic cereal production under northern temperate conditions. Undersown legumes, or whole-season green manure?
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Henriksen, Trond Maukon; Eltun, Ragnar.
Two systems for nitrogen (N) supply to organic spring cereals were compared under Norwegian conditions. Repeated undersowing of clover in the cereals in four growing seasons was compared to a whole-season green manure in the second year. Cereal yields were higher in the treatments with clover than in the controls. The yield increasing effect of undersown clover was residual. One year of whole-season green manure increased subsequent cereal yields significantly, but not enough to compensate for the loss of yield over the total four-year period. If phytopathological problems can be avoided, repeated undersowing of legumes seems to be more profitable than green manure each fourth year in stockless organic cereal production systems. The soil mineral N...

Yield stability of single and two-clover grass-clover swards at grazing, cutting and different fertilizer regimes
Provedor de dados: 21
Autores: Eriksen, J.; Askegaard, M.; Søegaard, K.
Increasing plant diversity in grasslands may improve productivity and yield stability. This study investigates in a field experiment, yield and quality of two-species swards of ryegrass/white clover and three-species swards of ryegrass/white and red clover at five different managements representing cutting, grazing, combinations of cutting and grazing and different fertilizer treatments in 1 to 4-yr-old swards. Generally, the three-species mixture produced higher yields than the two-species mixture when swards were young and lower yields when swards were 3 and 4 years old. Fertilizer responses were similar in both mixtures and also rather independent of sward age. The overall mean annual yield increase by slurry application was 1.34 t DM corresponding to...

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 der Zwischenfruchtgemenge auf Gesundheitsstatus oder...

Jordbearbetning är en effektiv kontrollmetod mot perenna ogräs, såsom kvickrot (Elymus repens L.), delvis på grund av att bearbetningen sönderdelar ogräsens underjordiska lagringsorgan (rhizom).  Jordbearbetning ökar dock risken för näringsläckage, och det är svårt att kombinera jordbearbetning med en växande gröda. I denna studie använde vi oss av en prototyp med vertikala diskar för att fragmentera kvickrotens rhizomer med minimal störning av jord och gröda. Målet var att utveckla en metod för kvickrotskontroll i gräs-klövergrödor med en kombination av rhizomfragmentering och putsning. Experimenten utfördes 2014 och 2015 i Uppsala, med rhizomfragmentering utförd innan sådd (TRF), i den växande grödan (SRF) eller både och (TRF + SRF)....

Einjährige Medicago- und Trifoliumarten als Bodenbedecker in Lebendmulchsystemen: Adaptation und Konkurrenzverhältnisse
Provedor de dados: 21
Autores: Baresel, Jörg Peter; Reents, Hans Jürgen.
The potential of self-reseeding annual clovers and medics (T. subetrraneum, T. campestre, M. minima, M. orbicularis) as continuous ground cover in living mulch systems with cereals in southern Germany was assessed. It could be shown, that all of the assessed species were winterhardy and were able to re-establish from seed. Competition of the legumes on rye was limited in the first year. The methods for seed-ing cereals into established legume stands have still to be improved.

Winterackerbohnen im Ökologischen Landbau:   Einfluss von Zwischenfrüchten und Sortenwahl auf Kornertrag und Unkrautbesatz
Provedor de dados: 21
Autores: Neuhoff, Daniel; Range, Jan.
Zwei Winterackerbohnensorten wurden über zwei Jahre an einem Versuchstandort im südlichen Rheinland nach drei verschiedenen Zwischenfrüchten (Sonnenblumen, Buchweizen, Selbstbegrünung) angebaut. Ziel war die Erfassung und Bewertung von Wachstums- und Ertragsparametern von Winterackerbohnen (WAB) sowie des Unkrautbesatzes.  Sonnenblumenzwischenfruchtanbau vor WAB hatte  eine tendenziell verminderten Unkrautbesatz im Vergleich zu Selbstbegrünung zur Folge. Gemittelt über zwei Versuchsjahre war der Kornertrag der WAB nach Zwischenfrucht Sonnenblumen und Selbstbegrünung signifikant geringer verglichen mit Buchweizen.

Mitigating greenhouse gas emissions from paddy farming by intercropping with other economically useful plants
Provedor de dados: 21
Rice is a major staple food crop and a significant natural source of greenhouse gas (GHG) emissions. A major increase in the production of rice will be indispensable in order to feed the burgeoning global population and in turn the GHG emissions –particularly methane and nitrous oxide – are expected to increase, unless new mitigation strategies are developed and applied.  This project explores the potential for developing new rice based cropping system integrated with novel strategies to mitigate GHG emissions. There are a number of aquatic plant species, which exists naturally in rice producing regions and are already part of human consumption in local cultures. We plan to test these plant species for their potential to reduce emissions of methane and...

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.

Actuellement, les problèmes de mauvaises herbes sont gérés en majeure partie par l'application d'herbicides. Cette utilisation généralisée permet de maîtriser la majorité des situations malherbologiques, mais elle génère des problèmes dont l'acuité va croissant: modification (appauvrissement) de la flore des parcelles cultivées, développement de biotypes résistants aux herbicides, contamination des eaux,…Dans ce contexte, l'allélopathie, c'est-à-dire les interférences entre plantes poussant dans la même parcelle, par l'intermédiaire de médiateurs chimiques, pourrait jouer un rôle intéressant.

Intercropping leek (Allium porrum L.) with dyer’s woad (Isatis tinctoria L.) increases rooted zone and agro-ecosystem retention of nitrogen.
Provedor de dados: 21
Autores: Xie, Yue; Kristensen, Hanne Lakkenborg.
Nitrate leaching can be high in organic vegetable production. Late-harvested crops like leek limit the use of autumn catch crops. The aim of this study was to investigate the growing of a combination of a deep-rooted catch crop and a shallow-rooted vegetable to reduce the risk of nitrate leaching. We compared a leek sole crop (S) with two intercropped systems of leek and early-sown dyer’s woad (five weeks after leek planting) (IE) or late-sown dyer’s woad (eight weeks after leek planting) (IL) in two seasons: 2012 and 2013. To reveal root and resource competition, leek with dyer’s woad rows left empty (Semp), and early and late-sown dyer’s woad with leek rows left empty (DEemp, DLemp) were included.

Inclusion of caraway in the ryegrass-red clover mixture modifies soil microbial community composition
Provedor de dados: 21
Autores: Cong, W.-F.; Jing, J.; Søegaard, K.; Eriksen, J.
Perennial ryegrass-clover mixtures are widely used in intensively managed grasslands due to their high biomass production. Recent studies have shown that inclusion of competitive forbs such as plantain enhanced above-and below-ground biomass of ryegrass-red clover mixtures (Cong et al., 2016), while inclusion of forbs such as caraway in the grass-clover mixture largely maintained the herbage yield. Meanwhile, inclusion of forbs increases plant litter diversity, which could change root quality of the plant community. Hence, changes in quantity and quality of root litter in forb-containing grass-clover mixtures may potentially affect soil microbial community structure, biomass and associated ecosystem functions, but it is yet to be elucidated. We...

LIVESTOCK IN ORGANIC FARMING – HOW IMPORTANT IS IT FOR SOIL FERTILITY MANAGEMENT?
Provedor de dados: 21
Autores: Schulz, Franz; Brock, Christopher; Leithold, Günter.
Stockless management is increasing even in organic farming, but it is not known until now, whether organic matter supply is sufficient in such systems, or which measures are necessary to achieve a sustainable soil organic matter (SOM) management. Results from the long-term Organic Arable Farming Experiment Gladbacherhof (OAFEG) show that after two 6 y rotations, only a “mixed farm” treatment (MF) with fodder legumes in the rotation and cattle manure application corresponding to 1 LU ha-1 was able to maintain, and in the long term perhaps increase, SOM levels. The “stockless farm” with fodder legumes as green manure ley (SFL) was barely able to maintain the SOM level, while the “stockless cash crop farm” where organic matter supply relied on green manure...

Vælg det rigtige tidspunkt til nedpløjning af efterafgrøden
Provedor de dados: 21
Autores: Olesen, Jørgen E.; Thorup-Kristensen, Kristian.
Brugen af efterafgrøder har to hovedformål: reduceret kvælstofudvaskning og øget N-forsyning til efterfølgende afgrøder. Efterafgrødens nyttevirkning i den efterfølgende afgrøde afhænger af, om kvælstoffrigivelsen tidsmæssigt falder sammen med afgrødens behov for kvælstof. Flere forsøg gennemført ved Danmarks JordbrugsForskning tyder på at man kan forbedre eftervirkningen af ef-terafgrøder betydeligt ved at vælge det helt rigtige nedmuldningstidspunkt. Det handler ikke blot om nedmuldning enten efterår eller forår. Forårsnedmuldning må ikke ske for sent. Efterårsned-muldning bør kun bruges på lerjorderne, og det må ikke ske for tidligt.

In organic farming legumes play an important role in crop rotation. Especially in stockless farming systems clover-grass is hardly cultivated any more, whereas grain legumes are preferred. The purpose of the field trials (2001-2004) was to examine the effect of field beans, grain peas, bush beans and red clover-grass compared with the control spring wheat on the following crop potato.Yield of potato following the cultivation of all legumes was on average significantly higher (13 – 16 %) than the previous crop spring wheat. No differences could be seen between the four legumes, but year effects were apparent. A significant increase of potato tuber yield after bush beans could only be achieved in two years when catch crop (Phacelia) had developed well....

Utilizing legume-cereal intercropping to increase self-sufficiency with animal fodder and maintain soil quality on organic farms in the Czech Republic
Provedor de dados: 21
The legume-cereal intercropping (LCI) has a long agricultural tradition and has been used as a part of the crop rotation on arable land for decades. The ability of LCI to reduce weeds, enrich the soil with nitrogen, suppress and disrupt the spread of pests and disease as well as to improve plant health is of special interest on organic farms. However, the LCI technique is currently not in use in the CR, not even in organic arable farming systems. Further, it is evident that information how to improve the organic feed availability, especially with concentrates, are highly required. It is necessary to offer to Czech organic farmers an alternative to lack of organic cereals and risky and expensive imports (GM- soya). The LCI could be a solution, but it is...

Climate-friendly food
Provedor de dados: 21
Autores: Olesen, Jørgen E.
Climate change is without doubt one of the greatest challenges mankind has ever faced. This is not least due to the enormous consequences that climate change will have for the world’s ecosystems and for our living conditions. At the same time, climate change is a colossal political problem, in which the world’s democracies run the risk not being able to carry out the decisions that have to be made.  The political and democratic problem builds on the very limited understanding that there is a connection between emissions of greenhouse gases, climate change and their impact on the living conditions of individual people.  In reality, there is both a spatial and a temporal separation between emissions and effects. The world’s industrialised countries, which...

Hairy Vetch – an Excellent Green Manure for Dry Conditions
Provedor de dados: 21
Autores: Alföldi, Thomas.
Hairy vetch (Vicia villosa Roth) produces a large amount of biomass even under dry conditions and is therefore an ideal green manure for Mediterranean cropping systems. However, the incorporation of this green manure into the soil is challenging.   This video presents three different machines – disk harrow, stone burier, and crimper roller – for the termination of hairy vetch. These machines have different degrees of conservation of soil fertility and the main pros and cons are discussed.  This video documents one of the field days within the TILMAN-ORG project (CORE Organic II) organized by the Italian research team CIRAA (Centro Interdipartimentale di Ricerche Agro-Ambientali and Scuola Sant’Anna Pisa, Italy).

The comparison of nitrogen use and leaching in sole cropped versus intercropped pea and barley
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Ambus, Per; Jensen, Erik Steen.
The effect of sole and intercropping of field pea (Pisum sativum L.) and spring barley (Hordeum vulgare L.) and of crop residue management on crop yield, NO3- leaching and N balance in the cropping system was tested in a 2-year lysimeter experiment on a temperate sandy loam soil. The crop rotation was pea and barley sole and intercrops followed by winter-rye and a fallow period. The Land Equivalent Ratio (LER), which is defined as the relative land area under sole crops that is required to produce the yields achieved in intercropping, were used to compare intercropping performance relative to sole cropping. Crops received no fertilizer in the experimental period. Natural 15N abundance techniques were used to determine pea N2 fixation.   The pea-barley...

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.

Nitrogen utilization in integrated crop and animal production
Provedor de dados: 21
Autores: Seuri, P.
The principles of organic production are based on integration between crop and animal production and self-regulated nutrient intensity. A comparison between specialized dairy and crop farm models and an integrated dairy and crop farm model showed 24 % higher total production per area and higher nitrogen utilization in the integrated system. The main factors were more efficient nutrient circulation, better utilization of legume crops and low intensity of nitrogen on non-legume crops.

In this study we assessed the genetic resources of three mountain oases in the al-Hajar range using a GIS-based field survey and farmer interviews. While arid conditions prevail throughout the mountain range, the different elevations of the oases in the Jabal al Akhdar mountains provide markedly differing agro-climatic conditions. Overall, 107 different crop species were identified belonging to 39 families. Species number was highest among fruits (33 spp.), followed by vegetables (24 spp.). Intensive irrigation allows cultivation of a broad range of species at all oases. However, the number of species varied significantly among sites. Fruit species diversity and homogeneity of the distribution of individual fruit species was highest at Balad Seet and...

Soil carbon storage and yields of spring barley following grass leys of different age
Provedor de dados: 21
Autores: Christensen, B.T.; Rasmussen, J.; Eriksen, J.; Hansen, E.M.
The inclusion of leys in arable cropping is generally found to improve soil fertility. The effect of leys depends on their botanical composition and management, but the significance of individual management factors remains confounded in most studies. We quantified the effects of one- to six-year-old pure grass leys on soil C (0-20 cm) and yields of three subsequent test crops of spring barley (Hordeum vulgare) under-sown with Italian ryegrass (Lolium perenne). Each ley was a mixture of four grass species (Lolium perenne, Festuca pratensis, Phleum pratense, Poa pratensis), exposed to three to four cuts annually. Only mineral fertilizers were applied (225 kg N ha-1 yr-1). The yield of barley was tested at six rates of N fertilizer (0 to 150 kg N ha-1). The...

The Danish organic crop rotation experiment for cereal production 1997-2004
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Askegaard, Margrethe; Olesen, Jørgen E.
In 1997 a crop rotation experiment was initiated at three sites in Denmark. The objective of the experiment was to explore the possibilities for both short-term and long-term increases in organic cereal production through manipulation of crop rotation design on different soil types. The experiment included three factors (proportion of grass-clover in the rotation, catch crops and manure application) in a randomised factorial design. The main indicators measured in the experiment were crop yield, nutrient leaching and weeds.    The crop rotation experiment has shown significant effects of location, crop rotation, catch crops and manure on yields, weed infestation, soil fertility and nutrient losses (Olesen et al., 2002; Schjønning et al., 2004; Askegaard et...

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.

Das Ziel unserer Praxisversuche besteht darin, die Kenntnisse über den Mischfruchtanbau unter Biobedingungen weiter zu vertiefen und für die Landwirte attraktiver zu machen. Das Hauptziel ist die richtigen Mischungspartner im richtigen Mischverhältnis zusammenzubringen und standardisierte Mischungen zu entwickeln. Die Proteinproduktion steht klar im Vordergrund und das Getreide soll die Funktion als Stützfrucht bzw. unkrutunterdrückende Begleitpflanze übernehmen.  Herbstsaaten haben gegenüber den Frühlingssaaten klare Vorteile wie frühere Blüte, bessere Konkurrenz gegen Unkräuter und weniger Schädlinge wie Blattläuse. Dies führt in der Regel zu höheren Erträgen. Als gewichtiger Nachteil der Winterformen hat sich in Jahren mit länger anhaltenden Kahlfrösten...

The production of bioenergy from local biological resources and the maintenance of soil fertility seem to have been opposing aims in organic agriculture (OA). It is however, important to reduce the reliance on fossil fuels and decrease greenhouse gas emissions in OA, especially in the context of enhanced integrity of OA.  This interdisciplinary project aims at developing new methods and processes for co-production of bio-ethanol, biogas and animal feed based on resources from OA and associated food processing and suggests the outline of a medium-sized plant for co-production of biogas, bioethanol, and animal feed. The project will also design and test a new cropping system for biomass production to be used for bioenergy, while at the same time safeguarding...

Forbs differentially affect soil microbial community composition and functions in unfertilized ryegrass-red clover leys
Provedor de dados: 21
Autores: Cong, WF; Eriksen, J.
Increasing plant diversity in agroecosystems is proposed to enhance multiple ecosystem services. Adding selected forbs such as caraway (Carum carvi L.) and plantain (Plantago lanceolata L.) to productive grass-clover mixtures can further enhance forage yields, root biomass, uptake of mineral nutrients and improve animal performance. Yet, it remains unclear whether and how adding these forbs to grass-clover mixtures can influence soil microbial communities and associated soil carbon (C) and nitrogen (N) cycling. Based on a three-year grassland experiment varying in species diversity and composition with and without fertilizer application, we determined soil microbial community composition and functions related to C and N cycling under laboratory...

Autores: Baldivieso-Freitas, Paola; Blanco-Moreno, José M.; Gutiérrez-López, Mónica; Peigné, Joséphine; Pérez-Ferrer, Alejandro; Trigo-Aza, Dolores; Sans, Francesc Xavier.
Earthworms are one of the most important soil macrofaunal groups, and they play a major role in agricultural ecosystems. Agricultural practices, such as reduced tillage, the use of green manures and organic fertilization, can be beneficial for earthworm populations in agricultural systems. However, under a Mediterranean climate, not much is known regarding their response to agricultural management. The aim of this study was to analyse the effects of tillage type, organic fertilization, and green manures on the density and biomass of earthworms in organic arable dryland. The trial was conducted in a four-year crop rotation with a complete factorial design that combined tillage system (mouldboard ploughing vs. chisel), fertilization (composted farmyard...

Sources of nitrogen for winter wheat in organic cropping systems
Provedor de dados: 21
Autores: Petersen, Søren O.; Schjønning, P.; Olesen, Jørgen E.; Christensen, S.; Christensen, B.T.
In organic cropping systems, legumes, cover crops, residue incorporation, and manure application are used to maintain soil fertility, but the contributions of these management practices to soil nitrogen (N) supply remain obscure. We examined potential sources of N for winter wheat (Triticum aestivum L.) in four experimental cropping systems established in 1997 on three soil types. Three of the four systems were under organic management. Topsoil N, depth of the A horizon, and cumulated inputs of N since 1997 were determined at plot level. Labile soil N pools (mineral N, potentially mineralizable N [PMN], microbial biomass N [MBN]) were monitored during two growth periods; at one site, biomass C/N ratios were also determined. Soil for labile N analysis was...

Some species, e.g. vetch and oilseedrape, do not tolerate traffic very well, whereas grasses, chicory and plantain tolerate traffic welll. Catch crops with a high risk of regrowth such as white clover and timothy-grass, need to be incorporated into the soil early and maybe more than once and are not suited for systems with reduced tillage, whereas vetch, oilseed rape and fodder radish have very low regrowth after mulching in spring.

Kalkulation der N2-Fixierleistung und der N-Flächenbilanz beim Anbau von Leguminosen im ökologischen Landbau
Provedor de dados: 21
Autores: Jost, Britta; Schmidtke, Knut; Rauber, Rolf.
During last years procedures were developed to calculate the N2 fixation and the N balance of grain and forage legumes under organic farming conditions. These proce-dures are distinctly improved by including the mineral soil nitrogen the legumes can use during the growing season. A system monitoring the plant available soil N was established in 2005 and 2006, which was distributed across Germany. Available soil N was assessed by means of non leguminous reference plants. Results from 2005 are recorded. It is the objective to make the calculation of the N balance of legumes inter-actively available in the near future via the internet portal ISIP (Informationssystem Integrierte Pflanzenproduktion). The target group are agricultural consulting services and...

Soil quality aspects of humid sandy loams as influenced by organic and conventional long-term management
Provedor de dados: 21
Autores: Schjønning, Per; Elmholt, Susanne; Munkholm, Lars J.; Debosz, Kasia.
The development of low-input farming systems requires knowledge of the extent to which management characteristics influence the soil as a habitat for micro-organisms and a medium for plant growth. This paper presents a study of long-term effects of organically and conventionally cultivated systems on a range of soil physical, chemical and biological characteristics in Denmark. Seven soils were included, falling into three groups (I¯III). Each group consists of an organically managed soil (Org) referenced by one or two conventionally managed soils (Conv) with the same soil type (sandy loam) and pedological history. All organically managed soils were dairy farm soils (H), which had been organically managed for 46, 47 and 40 years, respectively. They had...

Roots below one meters depth are important for nitrate uptake by annual crops
Provedor de dados: 21
Autores: Kristensen, Hanne L.; Thorup-Kristensen, Kristian.
The root depths of annual crops vary from 0.2 m to more than 2 m depending on root growth rate and length of growing season. However, studies of root growth and N uptake are often restricted to a depth of 1 m or less, as root biomass is assumed to be negligible below this depth. We have studied the importance of root growth and N uptake to a depth of 2.5 m in fully grown field vegetables and cover crops by use of minirhizotrons and deep point placement of 15N. Deep rooted crucifereous crops were found to have high root densities to a depth of 1.5-2 m and high 15N uptake to this depth. The work shows that knowledge of the interactions between root growth and soil N below a depth of 1 m are important to understand crop N uptake and nitrate leaching from...

Manipulating cover crop growth by adjusting sowing time and cereal interrow spacing to enhance residual nitrogen effects
Provedor de dados: 21
Autores: De Notaris, Chiara; Rasmussen, Jim; Sørensen, Peter; Melander, Bo; Olesen, Jørgen E.
Legume-based cover crop (CC) mixtures can increase nitrogen (N) availability in arable systems, reducing the need for external N inputs, as they retain soil N and fix atmospheric N2. However, they need sufficient biomass accumulation to influence soil N availability. Early establishment through undersowing can improve CC growth and plant N accumulation, but competition with the main crop should be minimized. This study aimed to investigate the effect of main crop inter-row spacing (12, 18, 24 cm), manure application (without, with) and CC undersowing (early, late, no cover crop) on N accumulation in a legume-based CC mixture and the residual N effect on the following crop. We conducted a field experiment in Denmark with spring wheat as main crop and spring...

Early interference dynamics in intercrops of pea, barley and oilseed rape
Provedor de dados: 21
Autores: Bellostas, Natalia; Hauggaard-Nielsen, Henrik; Andersen, Mette Klindt; Jensen, Erik Steen.
Intercropping, the practical application of ecological principles such as diversity, interference, competition and coexistence in agriculture, is gaining increasing interest in organic farming. To be able to improve the management of intercrops, a more detailed knowledge is required on aspects of interference between crops. A bioassay and a pot experiment were conducted to assess both the mechanisms and the time of expression of processes involved in the early interference between pea (Pisum sativum L.), barley (Hordeum vulgare L.) and oilseed rape (Brassica napus L.) when grown as intercrops. Conditions of non-limiting nutrient and water supply were chosen to eliminate competition for these growth factors. The bioassay gave no indication of competitive...

Autores: Askegaard, Margrethe.
Weed-suppressing crop rotations are essential for sustainable organic arable farming. Preventing spread of perennial weeds will increase crop yields and quality.  The tool is a factsheet created for all organic farmers as we all need renewed knowledge on weed-suppression and crop rotation from time to time.  The factsheet provides practical recommendations on crop selection and composition of crop rotations in accordance to weed competitiveness and nitrogen demand. An appropriate combination of crops and green manures, designed specifically for the conditions and needs of individual fields, prevents spread of perennial weeds. The factsheet doesn’t only focus on prevention but also provides recommendations in case of high weed pressure. Example: Do not sow...

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...

Soil mechanical behaviour of sandy loams in a temperate climate: case studies on long-term effects of fertilization and crop rotation.
Provedor de dados: 21
Autores: Munkholm, Lars J.; Schjønning, Per; Petersen, Carsten T.
Two case studies on Danish sandy loams investigated long-term effects of fertilization and crop rotation. Case Study 1 compared a diversely cropped organically farmed soil (DFG(1)) with a conventionally farmed soil predominantly growing annual crops (DFA), both receiving animal manure.  In Case Study 2, a diversely cropped organically managed soil DFG(2)) receiving animal manure was compared with an almost exclusively cereal cropped conventionally farmed soil receiving no animal manure (CCC). A multi-level experimental strategy was followed to compare integrating field methods with specialized laboratory methods. Ease of tillage was described in the field and characterized using a drop shatter field test and by measuring aggregate tensile strength. Fitness...

Ertragspotentiale ökologischer Anbausysteme aus pflanzenbaulicher Sicht
Provedor de dados: 21
Autores: Neuhoff, Daniel.
The potential of Organic Agriculture to feed the world is currently under discussion. Contrasting statements concerning this issue are mainly due to missing distinction between socio-economic and biophysical impact factors, to methodical issues of yield comparisons and to sole regional observations. Instead of comparing individual data sets in meta-analyses it is proposed to explore yield potentials of different systems from an agronomic perspective. Yields in organic systems are predominantly restricted by  N-availability as a function of legume growing. The potential of replacing mineral N by biological nitrogen fixation differs between regions, but generally limits the productivity of cereals. A major determinant for legume cultivation is low pressure...

Background  Agricultural production is challenged by the limitation of non-renewable resources. Alternative fertilizers are promoted but they often have a lower availability of key macronutrients, especially phosphorus (P). Biological inoculants, the so-called bio-effectors (BEs), may be combined with these fertilizers to improve the nutrient use efficiency.  Methods  The goal of this study was to assess the potential of three BEs in combination with alternative fertilizers (e.g., composted manure, biogas digestate, green compost) to promote plant growth and nutrient uptake in soils typical for various European regions. Pot experiments were conducted in Czech Republic, Denmark, Germany, Italy, and Switzerland where the same variety of maize was grown in...

In order to improve our understanding of soil aggregation, we have studied the relative importance of bonding and binding mechanisms, especially how they scale according to aggregate size and how they are influenced by farming system and different management options. Topsoil samples were collected from four arable sandy loam soils found as two pairs (FP1 and FP2) of neighbouring fields. One of the fields in FP2 had been grown for decades with annual cash crops without application of organic manures, while the other three fields had been managed with diversified crop rotations and manure dressings. Aggregates were segregated from the bulk soil by promoting brittle failure. The samples of soil structural units were fractionated to 4-8 mm, 0.5-1 mm and...

NDICEA presents an integrated assessment of the question of nitrogen availability for organic crops.  During the growing season, the model compares net available nitrogen from manures, crop residues, green manures, additional fertilisers and the soil, with the crop specific demand on a daily basis. The release of nitrogen from different types of organic matter in the soil is calculated, considering soil type, temperature, rainfall and losses due to leaching and denitrification.   The NDICEA model has been developed, tested and used during more than 15 years by the Louis Bolk Instituut in the Netherlands.

The arable vegetation of Baltic organic cereal fields as shaped by crop management
Provedor de dados: 21
Autores: Hofmeijer, Merel A.J.; Melander, Bo; Salonen, Jukka; Verwijst, Theo; Zarina, Livija; Gerowitt, Bärbel.
Weeds remain to be the main challenge within this agricultural system, especially perennials in the north European realm. Because of increased interest in agrobiodiversity functioning, weeds should be kept within manageable limits, while on the other side encourage a specie rich weed flora. One of the PRODIVA project objectives is to investigate to which extent these two aspects can be addressed through the use of diversified crop management. In order to research this objective, weed and management data were obtained from organic farms in the baltic region over the course of two years (2015-2016) in spring sown cereal crops. The impact of the local environment and management factors on the occurring weed communities was studied in multivariate analysis...

Effects of sowing measures on weeds and yield of organically grown wheat
Provedor de dados: 21
Autores: Verschwele, Arnd.
Weed control by harrowing is an essential measure in organically grown cereals, but it is also known to be less effective against perennial weeds. Such problems might be solved by using a more effective hoeing which needs wider row spaces. On the other hand, there is a risk of low competi-tiveness in wide crop stands, particularly if mechanical control effects are unsatisfying.  Therefore, a new approach has been investigated by using a crop design with alternating crop bands and crop-free bands. Using hoes in the crop-free band as well as a higher crop competitiveness within the crop band are two possible effects in order to make weed control more effective.

On-farm research for efficient organic matter management in low-input farming systems
Provedor de dados: 21
Autores: Ponzio, Carlo.
This thesis work has the objective to study alternative ways of managing the organic matter in diverse agro-ecosystems, focusing on both quantitative and qualitative aspects.  The effect of several organic matter-based farming practices, that are characteristic of the organic and biodynamic method, on biomass production, productivity, and soil microbial activity has been investigated through a multidisciplinary approach that embraced on-farm trials as well as reductionist greenhouse and laboratory experiments.  The open field trials have been conducted in organic commercial farms in the Marche region and in low inputs small subsistence farms in the African Kingdom of Swaziland. In both cases, the farmers were involved as "partners" in the research, which...

Nitrogen fixation and soil nitrogen in organic ley arable rotations
Provedor de dados: 21
Autores: Sanders, Ian; Watson, Christine; Rees, Robert; Atkinson, David.
This report was presented at the UK Organic Research 2002 Conference. Nitrogen (N) fixation in a white clover/ryegrass mixture was measured in 1,2,3 and 4-year-old organically managed leys during 2000. N fixation varied between 73.7 in 1-year-old leys and 33.5 kg ha-1 in 4-year-old leys. Soil nitrate-N, grass N yield and N content of grass and clover were all lowest in 2-year-old leys and highest in 3-year-old leys. The proportion of clover nitrogen derived from the atmosphere (pNdfa) was significantly lower in 3-year-old leys.

Controlled traffic farming increased crop yield, root growth, and nitrogen supply at two organic vegetable farms
Provedor de dados: 21
Autores: Hefner, M.; Labouriau, R.; Nørremark, Michael; Kristensen, Hanne Lakkenborg.
Increased farm machinery weight in agricultural production results in soil compaction. Controlled traffic farming (CTF) restricts traffic to permanent lanes, thereby creating traffic free beds for crop production. Field experiments were conducted at two organic vegetable farms in Denmark, on a sandy loam (2013–2016) and on coarse sand (2013–2015) to investigate CTF effects compared with random traffic farming (RTF) on vegetable yield, root growth, and soil mineral nitrogen (N). Root growth was measured using minirhizotrons. White cabbage, potato, and beetroot yield increased by 27%, 70% and 42%, respectively, in CTF compared with RTF in 2015 and winter squash indicated a yield increase of 43% on sandy loam in 2016. White cabbage (2015) and potato, beetroot...

Autores: Nykänen, A.; Jauhiainen, L.; Rinne, M.
In eastern Finland, 12 mixtures of spring wheat, spring barley, spring oats and/or rye with vetches and/or peas were evaluated in field experiments from 2005 to 2007 for their dry matter(DM) production, crude protein (CP) concentration and digestibility using three different harvesting times. Spring wheat-pea and spring wheat-vetch-rye mixtures produced the highest DM yields (5,000-6,000 kg/ha) while the lowest yields were found with spring oats-vetch (4,000 kg/ha DM). The highest CP concentrations were found in vetches (200 g/kg DM) and lowest in spring cereals (90-120 g/kg DM). Organic matter digestibility was highest in peas 700-750 g/kg) and lowest in spring rye and wheat (550-610 g/kg). It is suggested that decisions concerning when to harvest...

Intensively managed grasslands are dominated by highly productive grass-clover mixtures. Increasing crop diversity by inclusion of competitive forbs may enhance biomass production and sustainable biofuel production. Here we examined if one or all of three forbs (chicory, Cichorium intybus L.; caraway, Carum carvi L.; plantain, Plantago lanceolata L.) included in ryegrass-red clover mixtures enhanced above- and below-ground productivity, and assessed their biofuel potentials, based on a three-year experiment with and without fertilisation as cattle slurry. We determined herbage yield, standing root biomass, and estimated methane energy output and greenhouse gas (GHG) emissions per energy unit using life cycle assessment. Results showed that...

Direct drilling of winter cereals
Provedor de dados: 21
Autores: Bortolussi, Stefano.
Direct drilling has achieved results similar to conventional sowing techniques (including seedbed preparation) if the soil is well structured.    Practical recommendations    Observations and practical tips  • Pay attention to the soil structure when applying any mechanical operation. During the harvest, offloading should take place at the headlands.  • In the case of a high presence of deep-rooting weeds, choose a double-layer soil preparation (instead of compacting the soil) in order to increase porosity.  • Avoid sowing if heavy rains are expected in the next 5-6 days.  • Include cover crops in the rotation to improve soil structure. Cover crops are a key element to fine-tune direct drilling techniques.   • Directly drilled soil warms up more slowly in...

Rikkakasvit aiheuttavat merkittävää satohaittaa luonnonmukaisessa peltoviljelyssä. Yleisesti rikka-kasvien hallinta perustuu luomutiloilla mekaaniseen maanmuokkaukseen, josta kuitenkin aiheutuu myös negatiivisia ympäristövaikutuksia kuten maan rakenteen heikkenemistä ja ravinteiden huuh-toutumista. Peitekasvien viljely on mielenkiintoinen vaihtoehto luomutiloilla rikkakasvien hallintaan mekaanisen maanmuokkauksen sijaan. Samalla toteutustavasta riippuen peitekasveja voidaan hyö-dyntää biologisessa typensidonnassa, ravinteiden huuhtoutumisen vähentämisessä, eroosion estossa ja maan kasvukunnon ylläpidossa.

Autores: Pedrol, Nuria; Martínez, Antonio.
Within a schedule of long-term organic forage crop rotations, two mixed stands of ryegrass-clover were evaluated as following crops after winter cereal-legume mixtures under different sowing and tillage methods in Asturias (N. Spain). Significant differences were found in productivity, sward components, chemical composition and in growth dynamics. The crop sequence perennial ryegrass-white clover established under a triticale-field bean canopy produced an additional 6 t DM/ha, compared with oat-vetch followed by Italian ryegrass-red clover under regular post-harvest sowing, thus being a promising method for improving organic forage productions with minimum tillage. Changes in productivity and feeding values observed for both these ryegrass-clover swards...

Autores: LI, Mrs Zhifang.
This paper reports the trial comparing N management in two crop systems: winter wheat (Triticum aestivum L.) living mulch with subclover (Trifolium subterraneum L.)  (field 1), and winter wheat pure standing with organic N fertilization  (field 2). Subclover is supposed to fix N2 and to release a part of it to wheat plants. Wheat grain yield in field 1 is 2227kg/ha, in field 2 is 2272kg/ha, with no statistically-significant difference (95% level). However, the wheat biomass accumulation at the start of heading in field 1 (2635kg/ha) is significantly lower than that in field 2 (3100kg/ha). NPK content in wheat plant tissue is also obviously lower in field 1 than in field 2 during the stem extension stage. Soil soluble N content in field 1 is also lower than...

Strip cropping system for sustainable food and energy  production
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik.
Strip cropping is a strategy for subdividing single fields into strips with different crops in order to gain the same  positive effects known from crop rotations. No additional yield was found by using traditional market pricing,  however.  When including negative and/or positive yield effects in the interfaces between strips more or less the same biomass was produced when dividing the field into strips (6x6m) as compared to growing the same area with 50% annual crop + 50% perennial crop. Especially, the interspecific competitive ability of grass-clover during the initial growth stages reduces the final annual yields signi¬ficantly. So, why bother changing the well-known sole cropping practices? It is believed that the success of this strip cropping system...

The Effects of Crop Type and Production Systems on the Activity of Beneficial Invertebrates
Provedor de dados: 21
Autores: Eyre, M.D.; Volakakis, N.; Shotton, P.N.; Leifert, C.
Beneficial invertebrate activity (13 groups) was assessed in five crop types on a split-plot experimental system in northern England using pitfall trapping and suction sampling in May-October 2005. Very significant differences were detected in activity between crop type, and in the preference of groups for individual crops. Within crop types, differences in fertiliser and crop protection approaches appeared to significantly affect activity, with preferences for either organic or conventional management differing between groups. In general, inorganic fertiliser application had more effect on activity than pesticide, herbicide and fungicide use.

The development of improved guidance on the use of fertility building crops in organic farming (CTE0204)
Provedor de dados: 21
Fertility building crops are a key component of organic rotations where they help to provide nitrogen required for optimal crop performance. It is important that rotations and managements are planned which optimise the capture and use of this nitrogen. Some estimates are available of the nitrogen production from fertility building crops, but there was a need to produce a more comprehensive assessment of likely nitrogen fixation, release and availability under different circumstances. Thus the overall aim of the study was to provide guidelines to enable organic farmers to better estimate the nitrogen supply to a rotation following fertility building crops. This was done by a mix of literature review, empirical measurements, model development and farmer...

The nitrogen supply can be a yield-limiting factor in organic farming, especially when reduced tillage is applied. An organic field experiment was conducted from 2007 to 2013 to analyse the potential of the nitrogen supply through the efficient use of green manure crops in different tillage systems. Three farming systems were compared: a stubble cleaner system (SC) and a plough system (PL), both in a cereal-based crop rotation, and another plough system in a crop rotation that included alfalfa grass ley (PLALF). In the fifth year of the experiment, the experimental design was extended into a split plot design, and seven green manure treatments (Lolium perenne, Phacelia tanacetifolia, Sinapis alba, a mixture of Sinapis alba and Trifolium resupinatum,...

The long-term agronomic performance of organic stockless rotations
Provedor de dados: 21
Autores: Welsh, James P; Philipps, Lois; Cormack, William F.
This report was presented at the UK Organic Research 2002 Conference. Two long-term experiments were established with the aim of evaluating the agronomic and economic performance of organic stockless rotations. In total, four different rotations were evaluated at two sites in the south (Elm Farm Research Centre) and east (ADAS Terrington) of England. All of the rotations included either a one or two-year red clover green manure crop to provide nitrogen for subsequent crops and it was found that this was sufficient to support three or four years of arable cropping. Over a period of eleven years at EFRC and five years at ADAS Terrington, there was no evidence of a decline in crop yield, although there were significant year-to-year variations. Crop yields...

Autores: Paulsen, Dr. Hans Marten.
Yields of mixed cropping systems of winter rapeseed (Brassica napus) with winter rye, winter wheat and winter barley in organic farming are reported by the example of a one year field trial in Trenthorst, North Germany. The trial was established as per¬petuation of trials in the years before with different seed densities and row distances due to very low yields of both components to increase the overall yield of the mixtures. Winter rapeseed was heavily suppressed by the cereals when grown in mixture with rye. The winter rapeseed yields were more adequate in relation to the chosen seed reduction in combination with wheat. In systems with delayed drilling of the cereals between rows of rapeseed, wheat and barley had problems in field establishment and...

Integrated crop–livestock systems with agroforestry to improve organic animal farming
Provedor de dados: 21
Autores: Escribano, A.J.; Ryschawy, J; Whistance, L.K.
The livestock sector has to satisfy the growing demand for animal products while reducing its environmental impact, in face of great climatic and market changes.  For this reason, there is a necessity to redesign livestock production systems in order to make them more sustainable and adaptable. IFS (crop-livestock-trees) could be a viable option to achieve the above-mentioned global goals. Moreover, the implementation of conservation agriculture practices proved to improve crop-livestock beneficial effects. This review paper aims at highlighting the scientific knowledge existing regarding the advantages and limitations of crop-livestock systems including agroforestry and conservation agriculture practices. This shows that integration (this integration can...

Management of service crops for the provision of ecosystem services in vineyards: A review
Provedor de dados: 21
Autores: Garcia, Léo; Celette, Florian; Gary, Christian; Ripoche, Aude; Valdés-Gómez, Hector; Metay, Aurélie.
Service crops are crops grown with the aim of providing non-marketed ecosystem services, i.e. differing from food, fiber and fuel production. Vineyard soils face various agronomic issues such as poor organic carbon levels, erosion, fertility losses, and numerous studies have highlighted the ability of service crops to address these issues. In addition to their ability to increase soil organic matter and fertility, and reduce runoff and erosion processes, service crops provide a large variety of ecosystem services in vineyards such as weed control, pest and disease regulation, water supply, water purification, improvement of field trafficability and maintenance of soil biodiversity. However, associating service crops with grapevines may also generate...

Catch Crops in Organic Farming Systems without Livestock Husbandry - Simulations with the DAISY model
Provedor de dados: 21
Autores: Müller, Torsten; Thorup-Kristensen, Kristian; Magid, Jakob; Jensen, Lars Stoumann; Hansen, Søren.
This paper presents simulations of the soil-plant-atmosphere model DAISY based on an organic crop rotation with incorporation of different catch crops following pea as a leguminous cash crop. Special emphasise was put on the simulation of N-mineralisation/-immobilisation and of soil microbial biomass N. The DAISY model was able to simulate soil mineral N and soil microbial biomass N after soil incorporation of catch crop plant residues to some extend. Several processes need further attention and may be integrated into the DAISY model: (1) soil tillage induced mobilisation of organic material including considerable amounts of organic N, (2) winter killing of sensitive plant species and varieties, (3) decomposition of plant residues at the soil surface as...

Pflanzenbauliche Strategien für die ökologische Erzeugung von Verarbeitungskartoffeln - 1. Teil: Kleegrasmanagement
Provedor de dados: 21
Autores: Krause, Tanja; Böhm, Herwart; Loges, Ralf; Haase, Norbert U.
Die Erzeugung von Verarbeitungskartoffeln im ökologischen Landbau hat im Gegensatz zu Speisekartoffeln bisher noch eine geringe Bedeutung. Denn ein großer Anteil der ökologisch erzeugten Kartoffeln wird für die Direktvermarktung angebaut, nur rund die Hälfte gehen in den Großhandel oder Industrie. In den letzten Jahren wurden ca. 3.000 bis 5.000 t Kartoffeln zu Chips und vor allen Dingen zu Pommes frites verarbeitet, was einer Anbaufläche von max. 200 ha entspricht. Im Zuge der Ausweitung des ökologischen Landbaus und gleichzeitig steigender Nachfrage der Verbraucher nach Convenience-Produkten wie Chips und Pommes frites könnte die Erzeugung von Verarbeitungskartoffeln den Landwirten neue Einkommensquellen bieten. Wichtig ist dabei auch ein an die...

Crop agronomy in organic agriculture
Provedor de dados: 21
Autores: von Fragstein und Niemsdorff, P.; Kristiansen, P.
Organic crop husbandry is based on practices outlined in the various organic standards that have been developed and documented in many countries. The most widely recognised organic standards are those published by the International Federation of Organic Agriculture Movements (IFOAM 2002). Organic farming methods emphasise the use of internal on-farm inputs rather than externally sourced inputs to achieve essential soil fertility, nutrient management and plant protection goals. Self-regulation within an agroecosystem, multi-year management cycles and a focus on prevention rather than reaction, are key principles in organic farming that underpin organic plant production.

Wirkung des Gemengeanbaus mit Körnerleguminosen sowie der Standraumzuteilung und der Saatstärke auf Kornertrag und Kornproteingehalt von Winterweizen
Provedor de dados: 21
Autores: Hof, C.; Schmidtke, K.; Rauber, R.
In stockless organic farms it is difficult to produce winter wheat (Triticum aestivum L.) with high protein content. The objective of this study was to evaluate the effects of intercropping of (i) winter wheat with either winter field bean (Vicia faba L.) or winter pea (Pisum sativum L.), (ii) the spatial arrangement (mixed, row or row-strip intercrop) and (iii) the seeding rate of the wheat (100 or 20 %) on yield formation and grain protein content. Monocropped wheat planted at a seeding rate of 20 % significantly out-yielded monocropped wheat at 100 % seeding rate because of a more efficient use of the mineral nitrogen (N) in soil. A gradient in the spatial and temporal use of mineral soil N by the wheat was found. N was available in particular from...

Autores: Hüsing, Bianka; Wessel-Terharn, Michael; Vergara, Maria; Schön, Hans; Trautz, Dieter.
A field experiment was conducted during the 2011 growing season to determine the effect of inoculation with Bradyrhizobium japonicum on yield, crude protein content (%) and nitrogen content of five inoculated and not -inoculated soybean varieties (Klaxon, Protina, Gallec, ES Mentor and Aveline). At three defined points of time (BBCH 23, BBCH 69, BBCH 75) plant samples including the root system were taken for analysis regarding the nitrogen content. Soil analysis to determine the N-min content had been carried out. Concluding the yield and crude protein content of the varieties was determined. Significant differences between inoculated and not inoculated varieties could be verified concerning yield, crude protein content and nitrogen content.

Soil nutrient levels define herbage yield but not root biomass in a multispecies grass-legume ley
Provedor de dados: 21
Autores: Cong, W.-F.; Christensen, B.T.; Eriksen, J.
The response of above- and below-ground biomass to soil nutrient availability is crucial for estimating belowground carbon input and predicting changes in soil carbon storage. However, the response is far from clear at plant community level, especially for grassland systems. Using a long-term field experiment initiated 123 years ago with varying soil nutrient levels (deficient, sub-optimal, optimal and over-optimal) established by use of two nutrient sources (animal manure or mineral fertiliser), we examined the effects of soil nutrient level and source on herbage yield and composition, root biomass and root-to-shoot (R/S) ratio of an unfertilised multispecies grass-legume ley. Increased nutrient levels enhanced herbage yield, but did not affect root...

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 work is devoted to the evaluation and utilization of the STICS intercrop/sole crop model taking into account the European environmental variability within an organic farming framework. The model ability to simulate intercropping systems was evaluated on the network of the INTERCROP EU project experiments. We first realized the difficulty to simulate relevant absolute production values in spite of a satisfactorily phase of parameterisation in conventional farming experiments. We attributed most of the discrepancies between simulations and measurements to the non accounting of biotic stresses. However, the relative values and in particular the Land Equivalent Ratios draw to the same results for simulation and observa-tion, i.e. the global advantage of...

Twenty-six soil samples were collected from 13 paired orchards (organically vs. conventionally managed)  homogeneous for age, rootstock and cultivars, belonging to the Eastern Sicily Organic Citrus  farm Network. The soil quality was evaluated by chemical and biochemical indicators. The total  organic C, humification parameters and isoelectric focusing of extracted organic matter were measured  to quantify the size of relevant soil C pools. In addition, C turnover was evaluated by determining  microbial C mineralization, C microbial biomass and by calculating the mineralization and metabolic  quotient (qCO2). The results obtained demonstrated that organic citrus soils were characterized by a  general increase in all the organic matter pools, which means a...

KNOWING, CHARACTERIZING AND ASSESSING SYSTEMS OF ORGANIC CROP ROTATIONS
Provedor de dados: 21
Autores: fontaine, L.; fourrié, L.; Garnier, J.F.; Colomb, B.; Carof, M.; Aveline, A.
The choice of crop rotations in organic stockless cropping systems is the first leverage used to manage technical issues (to maintain soil fertility, to control pest and weeds) and economic issues (to insure income). The RotAB project (French Casdar funding 2008-2010) implemented complementary approaches to better knowing, characterizing and assessing arable crop rotations. Their conception depends on numerous factors such as the types of soil and climate (on which depend the types of crops, yield potential, possibility of mechanical weed control…) or the economic context (existence of outlets and continuity of markets). If nitrogen supply and weed control are the most important agronomic issues of organic farmers in stockless cropping systems, phosphorus...

Long term effects of cover crops on weeds in Mediterranean low input arable management systems
Provedor de dados: 21
Autores: Carlesi, Stefano; Antichi, Daniele; Bigongiali, Federica; Mazzoncini, Marco; Barberi, Paolo.
The introduction of cover crops (CC) in crop rotations is a key tool to control weed and ameliorate soil conditions in low input arable systems. In 1992 a long term experiment (LTE) was set up at Centre for Agri-environmental Research “E. Avanzi (CIRAA), University of Pisa to determine the combined effect of tillage intensity, nitrogen fertilization levels and CC types on soil quality, crop yield and weed communities.     The LTE is based on 4-year crop rotation (maize, durum wheat, sunflower, durum wheat) with cover crops grown twice, in between wheat and summer crops. Two tillage systems were compared: i) a conventional system (CS), with annual ploughing (30 cm depth); ii) a low input system (LIS), with chiseling (30 cm depth) for summer crops and no...

Der Kartoffelanbau ist ein wichtiges ökonomisches Standbein vieler Biobetriebe. Die intensive Bodenbearbeitung gefährdet die Bodenstruktur und erhöht das Risiko von Wasser- und Winderosion. Die regenerative Landwirtschaft hat den Anspruch, den Boden während des Anbaus zu verbessern, was in der Praxis erprobt und diskutiert wird. In einem einjährigen Experiment wurden Techniken der regenerativen Landwirtschaft auf den Kartoffelanbau angewandt und durch die erweiterte Spatendiagnose bewertet. Erste Ergebnisse zeigen, dass eine reduzierte Bodenbearbeitung mit und ohne Mulch die Bodenstruktur verbessert unter Beibehaltung wirtschaftlicher Erträge.

Catch Crop Residues Stimulate N2O Emissions During Spring, Without Affecting the Genetic Potential for Nitrite and N2O Reduction
Provedor de dados: 21
Autores: Duan, Yun-Feng; Hallin, Sara; Jones, Christopher M.; Priemé, Anders; Labouriau, Rodrigo; Petersen, Søren O.
Organic agriculture depends on recycling of N to sustain crop production, and the use of catch crops to prevent leaching losses during winter is part of this strategy. The finding in this study, that catch crop residues were a more consistent source of nitrous oxide emissions in spring than synthetic fertiliser, indicates catch crop residue decomposition may contribute negatively to the climate impact of the farming system. Management practices are needed that reduce the potential for denitrification, which is the main source of nitrous oxide. Possible strategies include cultivation to promote aerobic rather than anaerobic degradation, and timing of manure application to avoid that mineral N from manure accumulates during residue decomposition....

In diesem Artikel konnte nur ein sehr kleiner Einblick in das Projekt OSCAR gegeben werden. Inspirationen kommen vor allem aus Südamerika, wo die Direktsaat bereits Standard ist. Die erfolgversprechendsten Arten als Zwischenfrüchte und Untersaaten werden von mehreren Projektpartnern gemeinsam mit beteiligten Landwirten in der Praxis getestet. OSCAR wird jedoch zum Projektende noch keine fertigen Lösungen bieten können.  Mit dem sich deutlich wandelnden Klima auch in Deutschland werden Boden- und Wasserschutz immer wichtiger. Dazu tragen die Lösungsansätze von OSCAR bei. Es sind aber bereits einige Folgeprojekte entstanden.  Dazu gehört vor allem ein Projekt zur Züchtung von Untersaaten unter den Bedingungen der Minimalbodenbearbeitung.

Mixtures of modern and historical wheat cultivars under organic management in western Canada
Provedor de dados: 21
Autores: Pridham, Jackie; Entz, Martin.
Two historic (Red Fife and Marquis) and two modern (5602HR; AC Barrie) wheat (Triticum aestivum) cultivars were assessed to determine if cultivar mixtures provided a benefit to grain yield and disease and weed suppression in Manitoba over 3 site-years.  5602HR was the highest yielding sole cultivar while Marquis and AC Barrie were the lowest yielding sole cultivars. Red Fife yielded similar to 5602HR in several cases. Orthogonal contrasts across all site-years showed that 3 and 4 cultivar mixtures yielded similar (P&gt;0.05) to 5602HR, the highest yielding monocrop.

Management &amp; sustainability of stockless organic arable and horticultural systems
Provedor de dados: 21
Autores: Preston, Keith.
This review draws on the research into stockless systems and addresses the challenges of conversion planning, rotation design, maintaining soil nutrient status, weed control, pest control and economic return.     Traditional organic systems of mixed farming with alternate husbandry rely on fertility building leys and livestock manures to provide break crops and fertility building. However, the trend within agriculture has been a move away from mixed farming systems to specialist units. Stockless organic farming involves the use of green manures and green waste compost to replace livestock and animal manures.    The infrastructure costs (fencing, water and buildings) of introducing livestock into an all arable farm are often prohibitively expensive and...

Eftervirkning af rødkløver i rug
Provedor de dados: 21
Autores: Holm, Sandie.
Udbyttet i vårbyg efter forfrugt rødkløver er på niveau med tildeling af 40 kg udn. N/ha i gylle.  Rødkløver som undersået grøngødning har tilsyneladende en ukrudtshæmmende effekt både i udlægsåret og det efterfølgende år. Rødkløver egner sig godt til at blive undersået i foråret i rug, da den bliver for kraftig til de øvrige kornarter. Der sås 3 kg/ha i maks. ½ cm dybde med såmaskine.

Autores: Virkajärvi, Perttu.
Despite the relatively low tolerance against grazing and peaked DM production, timothy can be used effiently for grazing, especially in mixtures with meadow fescue. The growth processes lead to specific management options, e.g. early turnout, high pre-grazing sward heights, flexible grazing systems with large variation in rotation length, and possibly part-time grazing.

Sådan kan økologisk planteavl sænke udledningen af drivhusgasser
Provedor de dados: 21
Autores: Olesen, Jørgen E.
Både økologisk og konventionel planteavl udleder drivhusgasser, især lattergas og CO2. For at reducere den samlede belastning fra økologisk planteavl er det vigtigt at fokusere på sunde og konkurrencedygtige afgrøder, der giver høje udbytter og mindsker behovet for ukrudtsbekæmpelse. Efterafgrøder er med til at øge kulstofindholdet i jorden, men kvælstofrige grøngødningsafgrøder og efterafgrøder bør høstes og anvendes i biogasanlæg både for at øge udbyttet og for at mindske lattergasudledningerne.

Optimizing nitrogen utilization by ecological recycling agriculture (ERA)
Provedor de dados: 21
Autores: Seuri, Pentti.
The main purpose of agriculture is food production. There are always limited resources available for food production, thus the resource efficiency is always the key issue. The modern agriculture is using resources like external nutrients (fertilizers) and non renewable energy in large scale. The high production intensity results in high production per hectare, on the other hand it results also in serious environmental harms.Organic farming is based on more internal and renewable resources than conventional farming.Very often it results also in lower production intensity and lower production per hectare. There is a common criticism against organic agriculture as inefficient use of land and also inefficient use of nutrients and energy per output unit. Closer...

Effect of vetch wheat mixture and broccoli as preceding crops on organic summer vegetables: on farm trial in western Turkey
Provedor de dados: 21
Autores: ASLAN, Burcay.
Organic farming requires the use of practices such as crop rotation, green manure and compost application instead of chemical compounds to enhance farm productivity. In this study, effects of two pre-crops (vetch-wheat mixture and broccoli) and additional fertilization (AF) strategy (compost and commercial fertilizer) were tested on organic production of two main crops (tomato and zucchini) and on soil fertility. The main aim of this on-farm trial is to evaluate the applicability of the results obtained over four years study under experimental conditions. Pre-crops and AF strategy had no significant effect on zucchini yield; highest tomato yield was recorded after vetch-wheat mixture and AF. At the end of the cycle soil organic matter statistically...

Driftsformen har begrænset effekt på jordens evne til at holde på vandet
Provedor de dados: 21
Autores: Schjønning, P.; Iversen, B.V.; Jacobsen, O.H.
Mængden af organisk stof, som man påvirker med almindelig landbrugsdrift, har ikke nævneværdig indflydelse på jordens vandholdende evne.  Anvendelse af husdyrgødning i stedet for mineralsk gødning kan heller ikke forventes at påvirke jordens ledningsevne for vand i pløjelaget.   I forhold til ekstreme driftsformer med et ensidigt (korn-)sædskifte og uden anvendelse af organisk gødning vil en økologisk driftsform give både et større porevolumen og et mere forgrenet poresystem.   Et højt næringsstofniveau giver – uanset tildelingsmetode – flere store porer og bedre ledningsevne for vand i jordlaget under pløjedybde.

Dry matter yield, chemical composition and estimated extractable protein of legume and grass species during the spring growth
Provedor de dados: 21
Autores: Solati, Z; Jørgensen, U; Eriksen, J; Søegaard, K.
BACKGROUND: Knowledge of the variation of extractable protein amount in legumes and grasses as affected by harvest time is important for identifying optimal combinations to enable a high protein production in a biorefinery. The extractability of protein was estimated using the Cornell Net Carbohydrate and Protein System across six harvests during the spring growth.  RESULTS: The estimated extractable protein [g kg−1 dry matter (DM)] defined as the easily available fractions B1+B2 was significantly higher in white clover and lucerne at all harvests while, if the more cell wall attached fraction B3 can be extracted, white clover had the highest extractable protein amongst all species. Total yield of B1+B2 per ha was higher in white clover and red clover at...

Root pruning reduces root competition and increases crop growth in a living mulch cropping system
Provedor de dados: 21
Autores: Båth, Birgitta; Kristensen, Hanne L.; Thorup-Kristensen, Kristian.
In two field experiments, growth of white cabbage in pure stands was compared with that of cabbage grown in living mulch systems to reduce pest attacks. The roots of the living mulch were pruned early in the season, with the aim of reducing competition and increasing growth of the white cabbage. Root pruning was shown to increase the above-ground biomass of white cabbage, with two prunings giving higher cabbage yields than one, but there were clear differences between the living mulch species tested (red clover, birdsfoot trefoil, salad burnet, winter rye). Below-ground growth and competition were examined by measuring root distribution in minirhizotrons and uptake of 15N placed at different soil depths. These studies showed that the ability of mulch...

EFFECTS OF COVER CROP MANAGEMENT AND COMPOST APPLICATION ON SOIL FERTILITY OF ORGANIC MELON
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 enhancement and improvement of soil fertility is one of the principal aims of or-ganic agriculture. The practical realization needs a multi-annual, complex approach as well as the economic valuation. Exemplarily, it is shown for the use of green chop with wide C/N ratio in field beans. The cost-benefits-analysis is done with results from field trials and data from real farms. It includes the yield effects on beans and the following grain. Additional impacts like weed suppression and nitrogen fixation are estimated, too. The results show that the gross margin difference for beans is averaged  27 to  55 €/ha (depending on application techniques), but for grains +176 €/ha. Overall, the farms can gain +1 to +13 €/ha in average by using green chop to...

Provedor de dados: 21
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 long-term monitoring Trenthorst, situated near Lübeck in a temperate maritime climate on loamy soils, was established in 2003 and compares two cash crop and three livestock farming systems. We studied the soil mineral nitrogen contents of one cash crop and two livestock farms, specialised in dairy cows and goats/oilseeds resp., with the hypothesis that the livestock farms show a more even course of Nmin in the rotation and a higher rotation mean. The rotation average of Nmin in the cash crop farm was not lower than the ones in the livestock farms. But in the course of the rotations differences became evident: compared to the livestock farms the cash crop farm showed higher Nmin-values after the first rotation year (mulched vs. cut grass clover) but...

Mixtures of varieties of spring cereals for weed suppression in organic crop production
Provedor de dados: 21
Autores: Zarina, Livija; Kaczmarek, Sylvia; Melander, Bo; Sonderskov, Mette.
The suppression of weeds exerted by the crop plays a significant role for weed management in organic crop production. Crop species have different competitive abilities against weeds but also crop varieties vary in their suppression of weeds. Previous studies with varieties of spring cereals have demonstrated marked differences in the suppression of weeds caused by different attributes, such as stem height and leaf area index. However, little is known when different varieties of the same cereal species are mixed in different compositions both in terms of the number of varieties included and the seed rates at which they are established. Some studies have focused on yield and disease aspects but this study aimed to identify and select blends of cultivars of...

Reducing weed infestation in winter wheat by sowing technique
Provedor de dados: 21
Autores: Verschwele, Arnd.
Hoeing can improve weed control in cereals but this requires wider row spacing of the crop.  A spe-cific band row design may also ensure high crop yield and quality, especially at the conditions of organic farming. In order to study those effects two field experiments with winter wheat were con-ducted in 2005 and 2006 at the organic farming research area of the BBA. Three different row de-signs have been investigated: narrow (100 mm spacing), wide (400 mm) and band sowing (alternat-ing of crop band of 400 mm and a crop-free band of 300 mm width).  All plots were harrowed whereas the wide and band sown plots have additionally been hoed. Also two cultivars differing in growth habit and competitiveness were tested (Ludwig, Pegassos).

Nedfældet kvælstof skal placeres tæt ved afgrøden
Provedor de dados: 21
Autores: Petersen, Jens.
Konkurrence mellem afgrøde og ukrudt begynder allerede ved tilførsel af gødning. Direkte nedfældning af gødningen kan, i forhold til jævn indarbejdning i jorden, øge afgrødens optagelse af gødningskvælstof samtidig med, at ukrudtets optagelse af gødningskvælstof reduceres. Det er imidlertid en forudsætning, at gødningsstrengen placeres tæt på kornrækken. Dog bør alle kornrækker sikres lige adgang til gødningen. Ud fra en ren næringsstofsynsvinkel er der ikke den store forskel på, om det er gylle eller handelsgødning, der placeres. Placering af gødning foretages almindeligvis kun i forbindelse med såning af vårsæd, men der er også effekt af gødningsplacering i etablerede afgrøder. Der er dog væsentlige praktiske udfordringer forbundet med både placering af...

Farming practices are the key to maintaining and restoring farmland biodiversity. Selected farm management indicators, regarded as scientifically sound, practicable and attractive to stakeholders, were tested against species indicators in various farm types in 12 case studies across Europe. A set of eight farm management indicators is recommended, reflecting the pressure on biodiversity by farm management via energy and nutrient input, mechanical operations, pesticide use and livestock.

As plantas de cobertura propiciam a proteção e a reciclagem de nutrientes do solo, como o fósforo (P). Contudo, o teor e as formas de acúmulo de P podem variar entre espécies e sistemas de manejo de solo. O objetivo do trabalho foi avaliar as formas de acúmulo de P no tecido vegetal de plantas anuais de inverno, manejadas sob Sistema Plantio Direto (SPD) e Cultivo Convencional (SCC). O experimento foi instalado em 1986 no Instituto Agronômico do Paraná, em Pato Branco-PR, sobre um Latossolo Vermelho aluminoférrico. Ele se baseia no uso de seis plantas anuais de inverno (trigo, aveia branca, centeio, ervilhaca, nabo forrageiro e tremoço azul) que foram manejadas sob SPD e SCC. Em maio de 2011 as espécies foram semeadas, sem o uso de fertilizantes, e em...

Autores: Madsen, Helena; Talgre, Liina; Eremeev, Viacheslav; Alaru, Maarika; Kauer, Karin; Luik, Anne.
The effects of different winter cover crops and their combination with composted cattle manure on weeds and crop yields were investigated within a five-field crop rotation (barley undersown with red clover, red clover, winter wheat, pea, potato) in three organic cropping systems. The control system (Org 0) followed the rotation. In organic systems Org I and Org II the winter cover crops were used as follows: ryegrass (Lolium perenne L. in 2011/2012) and a mixture of winter oilseed-rape (Brassica napus ssp. oleifera var. biennis) and winter rye (Secale cereale L.) in 2012/2013 before pea; winter oilseed rape before potato and winter rye before barley. In Org II system composted cattle manure was also applied. In comparison with the control system, the...

Evaluation and design of multispecies cropping systems with perennials: are current methods applicable?
Provedor de dados: 21
Autores: Rapidel, Bruno; Meziere, Delphine; Metral, Raphaël; Dupraz, Christian; Mérot, A; Allinne, Clémentine; Gary, Christian.
The existing methods are applicable to multispecies cropping systems with perennials. However, the particular features of these cropping systems highlight the drawbacks of each of them. Therefore, combining these approaches, where and when it is possible, should be preferred. Whatever the method, evaluation of the new systems requires new indicators development, to account for the multiple productions with very different timescales and serving varying objectives. Development of simple and effective sets of indicators adapted to these systems is a powerful tool to boost the design realm, for practitioners and researchers alike.

Das Ziel unserer Praxisversuche besteht darin, die Kenntnisse über den Mischfruchtanbau unter Biobedingungen weiter zu vertiefen und für die Landwirte attraktiver zu machen. Die Hauptfrage ist die richtigen Mischungspartner im richtigen Mischverhältnis zusammenzubringen und standardisierte Mischungen zu entwickeln. Die Proteinproduktion steht klar im Vordergrund und das Getreide oder der Leindotter soll die Funktion als Stützfrucht bzw. Sekundärpflanze übernehmen. Bisher hat sich die Mischung von Eiweisserbsen und Gerste wegen dem gleichen Abreifezeitpunkt am besten bewährt. Bezüglich Proteinertrag schliesst die Mischung mit 40% der normalen Saatmenge Gerste weniger gut ab als die Mischungen mit nur 20% Gerste. Im Gesamtertrag hingegen liegen die...

Autores: Jing, J; Søegaard, K; Cong, W-F; Eriksen, J.
Plant species diversity may benefit natural grassland productivity, but its effect in managed grassland systems is not well understood. A four-year multispecies grassland experiment was conducted to investigate the effect of species diversity legumes and non-leguminous forbs on productivity, persistence and sward quality under cutting or grazing regimes and with or without slurry application. Three mixtures were established± 3-mix: grass, red and white clover, 10-mix: 3-mix plus birdsfoot trefoil and six non-leguminous forbs, and 12-mix: 10-mix plus lucerne and festulolium. Species diversity increased sward production and yield persistence under cutting regime. The 12-mix had the highest yield from the second year onwards and no statistically significant...

The thesis objective was to evaluate the forms of accumulation and release of phosphorus from cover crops waste under long time of different soil management systems and its relationship with the soil phosphorus forms. The experiment was established in 1986 on an Oxisol in the IAPAR experimental station in Pato Branco, Paraná State, Brazil. The treatments consisted of six winter cover crops (blue lupine, vetch, oats, radish, rye and wheat) and the winter fallow treatment, cultivated under no-tillage (NT) and conventional (CT). In September 2011 were collected soil samples (0-5 and 5-10 cm) and the shoots of winter cover crops. Confected litterbags (0.2 x 0.2 m) were collected at 7, 14, 28, 56 and 112 days after the cover crops management. In the residues...

Grain legumes and nitrate leaching: significance and prevention
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Jensen, Erik Steen; Aveline, Anne; Crozat, Yves.
The amount of internationally published evidence on the effects of grain legumes on nitrate leaching is sparse and some studies may have weak points. Nevertheless, this mini-review indicates that the level of N leaching is 0–20 kg N ha-1 greater after pea than after cereals. Methods to prevent N leaching should be further developed and there is a need to genetically improve the root systems of grain legumes.

Leguminous cover crops are one important source of nitrogen in organic stockless farming. Therefore the influence of six legume species in pure stands and one grass-clover mixture on grain yield and quality of the undersown winter rye and of the succeeding crop spring oat was examined. Three field trials were conducted at one experimental site in southern Bavaria (2005/06/07 until 2007/08/09; in 2005/06/07 only three of six leguminous undersowings). Additionally, after the harvest of rye two stubble seeds (clover in pure and mixed stands with vetch and mustard) and a control (rye without cover crop) were established in each year.   The cash crop was not affected by the undersown variants with respect to grain yield and quality. However, grain yield of the...

Data on the potential of intercrops to reduce soil nitrate contents, on their N accumulation and biological nitrogen fixation (BNF) are lacking for organic farming in the dry, pannonic region of Eastern Austria. The effect of legumes, non-legumes, and legumes + non-legumes used as intercrops on inorganic soil nitrogen, crop yield and biomass N, and BNF were tested in comparison to bare fallow. Non-legumes and legumes + non-legumes were more efficient than legumes in reducing inorganic soil N contents in autumn and nitrate contents in soil solution from the subsoil in winter. This reduction in inorganic soil N did not last until March of the following year due to an N mineralisation from the mulch. The legume + non-legume mixture contained a larger amount...

Autores: Migliorini, Paola; Vazzana, Concetta.
The research is aimed at implementing a methodology in order to estimate the sustainability of an agricultural system, through the use of Agro-ecological and Sustainability Indicators. The methodology is applied to three stockless, experimental agricultural systems, part of a long-term experiment (MOLTE) managed with diverse typologies (old organic, new organic vs conventional). The results derived from the three different management systems are estimated by considering crop rotation and efficiency in terms of energetic, macro-element (N, P, K) and organic matter flow. These are related to the landscape and biodiversity system, as well as the soil and the environmental system. The research shows that the agro-ecosystems managed with the organic agriculture...

Thanks to positive interactions between species, growing mixtures of cover crops allows improving the ecosystem services provided by cover crop cultivation. In this study, the influence of species diversity but also of species identity and mixture composition on cover crop biomass production and its stability in diverse growing conditions was studied. Several field experiments (varying soil type, preceding crop, soil tillage, sowing density, nitrogen fertilization and spatial replication) were set up in Switzerland during the period 2013−2016. In these experiments, the performance of cover crop species grown as sole crops was compared to that of multispecific mixtures. Part of these experiments followed a simplex design in which four cover crop species...

The need for breeding for cereal legume combinability: experiences in The Netherlands
Provedor de dados: 21
Autores: Prins, Udo; Nuijten, E.H.A.C.P.
Particularly for organic farming, mixed cropping of cereal and legume crops can provide advantages in terms of nutrient use efficiency, weed suppression and more stable yields. Cereals benefit from the nitrogen fixing ability of legumes, which also result in higher protein levels in the cereal crop, improving its quality as fodder and potentially also as food. Grain legumes benefit from the reduced weed pressure in cereal crops. In the past 10 years, various combinations of cereal (particularly wheat, barley, oats and triticale) and legume (faba bean, peas and lupins) crops have been tested by the Louis Bolk Institute. To optimise the crop mixtures, each combination requires specific traits of the cereal and legume crop. So far, breeding has focused on...

Legumes in Finnish agriculture: history, present status and future prospects
Provedor de dados: 21
Autores: Stoddard, Frederick L.; Hovinen, Simo; Kontturi, Markku; Lindström, Kristina; Nykänen, Arja.
Legumes are important in world agriculture, providing biologically fixed nitrogen, breaking cereal disease cycles and contributing locally grown food and feed, including forage. Pea and faba bean were grown by early farmers in Finland, with remains dated to 500 BC. Landraces of pea and faba bean were gradually replaced by better adapted, higher quality materials for food use. While grain legumes have been restricted by their long growing seasons to the south of the country, red, white and alsike clovers are native throughout and have long been used in leys for grazing, hay and silage. Breeding programmes released many cultivars of these crops during the 1900s, particularly pea and red clover. A.I. Virtanen earned the 1945 Nobel Prize in Chemistry for his...

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...

Autores: Goodlass, G; Hatch, D J; Shepherd, M A; King, J A; Cuttle, S P; Roderick, S; Briggs, S.
Optimising the amount of nitrogen captured by fertility building crops is essential for successful organic farming. This study used a combination of literature review, empirical measurements, model development and farmer participation to produce improved guidelines on making the most of soil nitrogen for organic farmers and growers. The main field experiment examined the impact of cutting and mulching on the build up of soil nitrogen. Recommendations to organic farmers from this part of the work, are that cutting and removing herbage during the fertility building phase promotes the highest amount of nitrogen fixation. However the highest soil residues occurred when clover was mulched in situ. Application of organic manures to legumes should also be avoided...

Root pruning reduces root competition and increases crop growth in a living mulch cropping system
Provedor de dados: 21
Autores: Båth, B.; Kristensen, H.L.; Thorup-Kristensen, K.
Living mulch systems may decrease pest attacks. However, the below-ground competition from the living mulch may decrease the growth of the cash crop. Here growth of white cabbage in living mulch systems and in pure stands was compared. Root pruning of the living mulch increased the above-ground biomass of white cabbage, with two prunings giving higher cabbage yields than one. Below-ground growth and competition were examined by measuring root distribution in minirhizotrons and uptake of 15N placed at different soil depths. These studies showed that the ability of mulch species to compete for resources at depth was restricted by pruning.

Biogas production is a key technology for sustainable use of biomass from agricultural production. An optimisation of biogas production from energy crops should not confine to the consideration of the biogas process. To assure a durable success, cropping of energy plants has to be designed according to the principles of sustainable crop rota-tions. Only in site-adapted and ecologically balanced crop rotation systems, energy crop production is meaningful. The general aim of this study was to develope site-adapted crop rotation systems including energy crops as main and catch crops.   Study regions were chosen to represent large regions of Austria.

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.

Autores: Pommeresche, Reidun; Hansen, Sissel; Eltun, Ragnar; Korsaeth, Audun.
Six cropping systems, ranging from conventional arable without livestock to organic livestock farming dominated by ley, have been compared in 1990 and 2004 in SE Norway. Ley in the crop rotation increased density and biomass of earthworms and channels in both organic and conventional systems. A ley proportion higher than 25 % only increased the density of channels. Among the arable systems, the organic system had a higher density and biomass of earthworms as compared to the conventional systems. Among the fodder systems, the optimised system had the highest density of earthworms in 2004, but there were no differences between these systems in earthworm biomass or density of earthworm channels.

In this 28-day laboratory incubation study, we examined the carbon (C) and N dynamics and N2O evolution after simulated incorporation of residues from three catch crop species into a loamy sand soil, with variable soil moisture (40, 50 or 60% water-filled pore space (WFPS)). The catch crops include two leguminous (red clover and winter vetch) and one non-leguminous species (ryegrass). Plant material was placed in a discrete layer surrounded by soil in which the nitrate (NO3-) pool was enriched with 15N to distinguish N2O derived...

Provedor de dados: 21
Autores: Verwijst, Theo; Lundkvist, Anneli; Pers Berglund, Anna; Krawczyk, Roman; Kaczmarek, Sylvia.
The aim of the studies performed in PRODIVA working package 2 was to assess the weed suppressive ability of crop mixtures (spring barley + peas) compared to ability of pure crops to suppress weeds. The work was done by means of field trials in which natural weed populations were used while controlled experiments were used with Elytrigia repens or Sinapis alba as a model weeds. Over a period of three years, 5 field experiments and 9 experiments under controlled conditions were performed in Poland and Sweden.       In all experiments, performance was assessed in terms of the crops ability to compete against weeds (AC). The ability to withstand competition from weeds (AWC) and the relative weed biomass in the intercrop, compared to weed biomass in the sole...

Zwischenfrüchte als Vorfrüchte für die Ertrags- und Qualitätsleistung von Mais und Kartoffeln
Provedor de dados: 21
Autores: Kolbe, Hartmut.
Catch crops of different species (legumes (I), legume and non-legume mixtures (II), grasses (III), herbs (IV), without (V)) lead to yield increasing (potato tuber) and also to yield decreasing effects (silage maize) of the subsequent crops. Main reason for these results seems to be differences in the C/N rations, so that especially in organic farm-ing the catch crops have to plough under in a relatively young growth stage. Over this, most catch crop species have had small but significant increasing effects on the con-tents of N, P, K, Mg and further ingredients of the following crops.

Pore characteristics and hydraulic properties of a sandy loam supplied for a century with either animal manure or mineral fertilizers
Provedor de dados: 21
Autores: Schjønning, P.; Iversen, B.V.; Munkholm, L.J.; Labouriau, R.; Jacobsen, O.H.
Application of organic residues to soil is generally assumed to improve soil tilth. Only few studies have reported on the long-term effects on the more subtle aspects of soil porosity and no reports have considered the potential effects of organic amendments on the pore system in the subsoil. We sampled undisturbed soil cores (100 cm3 and 6280 cm3) in metal cylinders in differently fertilized plots in the long-term field experiments at Askov Experimental Station, Denmark. We selected the 0-60 cm soil layer of plots dressed for a century with either mineral fertilizers (labelled NPK) or animal manure (labelled AM). Both fertilization treatments were studied at two levels of nutrient application: 'normal' (labelled '1') and 1.5 times 'normal' (labelled...

Autores: LIMA, Karla A. O.; NÃÃS, Irenilza de A.; GARCIA, Rodrigo G.; BORILLE, Rodrigo; CALDARA, Fabiana R.
Broiler production is highly dependent on the use of artificial light. The light source may affect the effectiveness of housing conditions due to increasing ambient temperature and concentration of noxious gases. This research aimed to evaluate the effects of different bulb types on the thermal, aerial, and acoustic environment of broiler aviaries. The experiment was carried out at a commercial broiler farm in Dourados, Mato Grosso do Sul State, Brazil. Three aviaries were used, and two flocks of male broilers from Cobb® genetic strain were reared from the first day to slaughter. Each aviary was equipped with a different light source, comprising the adopted treatments (A1 - incandescent light bulb, control; A2 - sodium vapor light bulb; A3 - fluorescent...

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.

Rhizodeposition of nitrogen by red clover, white clover and ryegrass leys
Provedor de dados: 21
Autores: Høgh-Jensen, Dr Henning; Schjoerring, Dr Jan K.
Correct assessment of the rhizodeposition of N in grassland is essential for evaluation of the biological N2-fixation of legumes, for the total N balance of agro-ecosystems, and for the pre-cropping value of  grasslands. Using a leaf-feeding technique by which plants were 15N labelled while growing in mezotrons in the field, the rhizodeposition of N by unfertilised red clover, white clover and perennial ryegrass growing in pure stands was shown to amount to 64, 71 and 9 g N m-2, respectively, over two complete growing seasons. The corresponding values for red clover and white clover growing in mixtures with ryegrass were 89 and 32 g N m-2, respectively. The rhizodeposited N compounds, including fine roots, constituted more than 80% of the total...

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

Diversity of organic farming systems: Challenges for the construction of markets, varieties and plant breeding techniques
Provedor de dados: 21
Autores: DESCLAUX, D.; CHIFFOLEAU, Y.; NOLOT, J.M.
New societal values call for the diversification of agriculture to fit contrasted environments. This process can be depicted by four models defined by two axes, a socio-economic axis (individual logic vs. collective governance), and an agro-ecological axis (analytical vs. systemic approaches). These models differ in: (i) their objectives (from improvement in yield to the empowerment of farmers), (ii) their specific expectations with respect to genotypes (from inherited genetic resources to varieties that represent genetic, ethical and social progress), and (iii) their representations of the environment (from a simple interaction between the bio-physical environment and crop management, to a complex interaction including the skills of stakeholders, outlets,...

Provedor de dados: 21
Autores: Sánchez‐Esteva, Sara; Gómez‐Muñoz, Beatrice; Stoumann Jensen, Lars; Neergaard, Andreas de; Magid, Jakob.
Background: Penicillium bilaii may enhance P availability to plants, since it has been shown to increase plant growth and P uptake. There is currently increasing interest in using microorganisms to promote P mobilisation from organic P sources. An investigation was conducted to determine the e ects of P. bilaii on P uptake and growth of wheat in the presence and absence of sewage sludge. Two soils di ering in P contents and pH were used, as it was hypothesised that these a ect the e ciency of P mobilisation.  Methods: A pot experiment, in which wheat was grown for 35 days in a moderately acidic soil of low P status and a calcareous soil of moderate P status, was conducted. A full factorial design was used with two non‐sterilised soils, three amendments...

Background and aims While N2-fixation in diversified grasslands including forage legumes and non-legumes has been widely studied, N2-fixation in swards containing only forage legumes remains unclear. In this study, we investigated N2-fixation in pure stands and mixtures of three forage legumes. Methodology N2-fixation, dry matter (DM) and nitrogen (N) yields were quantified in a field experiment for red clover (Trifolium pratense L.), white clover (Trifolium repens L.) and lucerne (Medicago sativa L.) pure stands and mixtures using the isotope dilution method. Results All three forage legume species derived most (around 85%) of their N from atmospheric N2-fixation (%Ndfa). However, no positive effect of species diversity was found in any of the mixtures....

Repeated clover subcropping as a strategy for commercial organic grain production
Provedor de dados: 21
There is a shortage of organic grains, and  a need to develop organic production systems which ensure high and stable grain yields. Commercial organic grain production is mainly a task for farms with few or no livestock, and the development of well functioning strategies for nutrient supply and weed control in commercial organic cereal production under such conditions, is a considerable scientific challenge. The nutrient losses should be minimized and grain yields maintained at economically satisfactory levels over time. A promising strategy involves undersowing of clover in grains where yields can be taken and nitrogen (N) be supplied simultaneously. The main objective of this project was to evaluate if repeated undersowing of clover is a well functioning...

Vegetables are among the main ingredients of the Mediterranean cuisine and thus enlarging organic local markets increase their demand for a diversity of vegetables. Long-term rotations based mainly on vegetables are rather rare in the Mediterranean countries. A four year experiment was carried out between 2006 and 2010 at Ege University Department of Horticulture in cooperation with CIHEAM Mediterranean Institute of Bari. And two different pre-crops, broccoli and vetch were tested under an organic management system as compared to fallow during the autumn-winter period. The summer main crops were rotated between solanaceous and cucurbitaceous vegetables as tomato (2007), zucchini (2008) pepper (2009) and eggplant (2010). The experiment aimed at recommending...

Roots below one meters depth are important for nitrate uptake by annual crops
Provedor de dados: 21
Autores: Kristensen, Hanne L.; Thorup-Kristensen, Kristian.
The root depths of annual crops vary from 0.2 m to more than 2 m depending on root growth rate and length of growing season. However, studies of root growth and N uptake are often restricted to a depth of 1 m or less, as root biomass is assumed to be negligible below this depth. We have studied the importance of root growth and N uptake to a depth of 2.5 m in fully grown field vegetables and cover crops by use of minirhizotrons and deep point placement of 15N. These data were used for calculation of the potential rate of nitrate uptake below 1 m depth. The rate was found to be significant for the six crops studied. The effect of root depth on soil N left by an annual crop was simulated with the EU-rotate N model. The results showed that deep rooted crops...

Autores: Klimekova, Marta; Lehocka, Zuzana.
In the 2003 – 2005 years we observed the effect of three different forecrops (sugar beet, winter wheat, maize for grain) on yield height and selected qualitative characters of spring barley (Ebson variety) growing in organic farming system in the stationary field experiment, established on degraded Chernozem on loess in maize – barley growing region in south – western part of the Slovak Republic (near Piešťany city). The results showed that the statistically highest yields were obtained after sugar beet. Selected qualitative parameters of spring barley (protein content, extract, starch content, thousand grain weight) were more suitable for barley processing for malting purposes after maize for grain and winter wheat.

Er der krummer i din jord – eller er det bare knolde
Provedor de dados: 21
Autores: Elmholt, S.; Schjønning, P.; Munkholm, L.J.
Jordens krummer er vigtige for vækst. Både vækst af afgrøden og de svampe og bakterier, der laver bindemidler til nye krummer. Vi har undersøgt, hvordan praktisk økologisk og konventionel drift påvirker dette samspil. Et varieret sædskifte med meget græs og husdyrgødning gav gode stabile krummer med højt indhold af biologiske bindemidler. Et ensidigt kornsædskifte med kunstgødning gav i stedet stabile knolde, hvor bindemidlet var ler. Sådan nogle knolde kan give et dårligt såbed, fordi våd jord bliver blød som mudder og tør jord hård som beton.

Einfluss verschiedener Zwischenfrüchte als Vorfrüchte für die Ertrags- und Qualitätsleistung von Silomais und Kartoffeln
Provedor de dados: 21
Autores: Schliesser, Ingeborg; Schuster, Martina; Kolbe, Hartmut.
Mehrjährige Gefäß- und Feldversuche des Landesamtes für Umwelt, Landwirtschaft und Geologie in Sachsen zeigen, dass Zwischenfrüchte zu höheren Erträgen bei Silomais oder Kartoffeln führen können. Zudem konnte bei bestimmten Zwischenfrüchten eine deutliche Verringerung des Nitratgehalts im Boden nachgewiesen werden.  Insbesondere der Anbau von Weißem Senf, Sommerraps, Phacelia und Welschem Weidelgras verringerte den Nitratgehalt um bis zu 75 Prozent des Bodenausgangsgehaltes. Ähnliche Wirkung zeigten das Landsberger Gemenge und ein Gemenge aus Phacelia, Buchweizen und Platterbse. Damit können Zwischenfrüchte gut zur Verringerung des Nitrateintrags ins Grundwasser beitragen.    Bei reinen Leguminosen ist die Nitrataufnahme aus dem Boden aufgrund ihrer...

“Strategies” to sustain crop productivity by reducing the fertilizer and lime demands must be developed. The use of plant species that use more efficiently the soil nutrients and tillage systems that provide nutrients accumulation in more labile forms are prerequisites for sustainable agroecosystems. This study aimed to evaluate the long period effect of cultivating different winter species under different soil management systems on vertical distribution of soil nutrients and the soil acidity distribution in soil profile. The experiment was established in 1986 with six winter treatments (blue lupine, hairy vetch, oat, radish, wheat and fallow) under conventional tillage (CT) and no-tillage (NT) in a very clayey Rhodic Hapludox in Southern Brazil.

Autores: Pedersen, Anders; Zhang, Kefeng; Jensen, Lars Stoumann; Thorup-Kristensen, Kristian.
The modeling of root growth in many plant–soil models is simple and with few possibilities to adapt simulated root proliferation and depth distribution to that actually found with different crop species. Here we propose a root model, developed to describe root growth, root density and nitrogen uptake. The model focuses on annual crops, and attempts to model root growth of different crop species and row crops and its significance for nitrogen uptake from different parts of the soil volume.

Autores: Steffens, Diedrich; Stamm, Roland; Leithold, Günter; Schubert, Sven.
Obwohl die agronomische Wirksamkeit von weicherdigem Rohphosphat gering ist, wird weicherdiges Rohphosphat im organischen Landbau gedüngt. Das Ziel des Projektes war es in Feld- und Gefäßversuchen in einer Fruchtfolge 2002/2003 und 2003/2004 zu prüfen, ob weicherdiges Rohphosphat von phosphataneignungseffizienten Pflanzen (Weißlupine und Ackerbohne) für phosphataneignungsineffiziente Pflanzen (Spinat und Mais) mobilisiert wird. Es zeigte sich, dass die P-Aufnahme von Spinat in einer Fruchtfolge mit Weißlupine und Ackerbohne höher war als in einer Fruchtfolge mit Sommerweizen. In Gefäßversuchen führte die Applikation von neuem Thomasphosphat (CaHPO4) zu einer höher Phosphataufnahme der Pflanzen als Rohphosphat.

Post-harvest effect of cover crops on creeping thistle Circium arvense
Provedor de dados: 21
Autores: Thi Thuy, Hong Phan; Thorup-Kristensen, Kristian.
Cover crops move nitrogen (N) to the top soil. This enhances the N uptake of the succeeding barley crop, especially at early growth stages, and limits the access of the thistle to the N from the subsoil. The autumn tillage for perennial weed control, in contrast, provides a N distribution favorable for the uptake by thistles rather than barley crop. The evidence of post-harvest effect of cover crops on the N status of C. arvense gives a better understanding of their roles in weed control.

Provedor de dados: 21
Autores: Petersen, Maja Eline; Bertelsen, Inger.
By establishing catch crops in connection with the last weed control in the row in a grain crop and weed control row in the stubble after harvest, it is possible to do mechanical weed control of the entire cultivated area during the growing season and at the same time to have vegetation.   Thistles (Sonchus and Cirsium) will be reduced by weed control between rows of catch crop after harvest, but only when weed control between crop rows has also been carried out. Common couch grass is not reduced significantly, but needs more vigorous weed control in the stubble

Organic matter and soil tilth in arable farming: Management makes a difference within 5-6 years
Provedor de dados: 21
Autores: Schjønning, P.; Munkholm, L.J.; Elmholt, S.; Olesen, J.E.
Management-induced depletion in soil organic carbon (SOC) may create critical tilth conditions for arable farming. We investigated the short-term effect of crop rotation and addition of animal manure on SOC fractions, the dispersibility of soil clay, the length of fungal hyphae, wet aggregate stability, tensile strength of dry aggregates, and the pore size distribution, gas diffusivity and permeability of undisturbed bulk soil. SOC fractions were measured in whole-soil samples and in 1-2 mm air-dried aggregates. Plough layer soil was sampled five and six years after the start of a field experiment with different cropping systems at two loamy sand soils (Foulum, ~9% clay and Flakkebjerg, ~14% clay).

Cauliflower (Brassica oleracea L. var. botrytis) has high nitrogen (N) demand during growing, but due to its low N use efficiency and N-rich residues, it may cause N losses by leaching after harvest. A field experiment was conducted to investigate the effect of overwintering grass-clover as an intercrop and moderately reduced N fertilization on organic cauliflower yield and risk of nitrate leaching. The experiment tested sole-cropped (S) and intercropped (I) systems using a substitution design and two N fertilizer rates (180 and 230 kg N ha−1). To investigate the competition between cauliflower and grass-clover, cauliflower grown alone with empty grass-clover rows (Semp) and grass-clover grown alone with empty cauliflower rows (GCemp) were included.

Field trials on reduced soil tillage under organic farming conditions across Europe were used to compare the soil quality changes over time. Soil organic carbon fractions, soil carbon stocks and microbial community structure were analysed. Most severe differences between plough and reduced tillage were found in the top ten cm of the soil profile. Differences became less or not significant in deeper layers. Analyses are still ongoing and will only be ready to be presented at the conference.

A whole range factors and their influence the potential of legumes as nitrogen suppliers to subsequent crops. The experiments were aimed to assess the impact of several legumes  to crop yield in organic crop rotation. Diferent field studies were conducted on a loamy Endocalcari-Epihypogleyic Cambisol in Dotnuva (55o 24' N). The effect of differ-ent legume/grass swards on the subsequent winter wheat crop depended on sward composition, and highest grain yield was obtained after ploughed-in lucerne. Spring wheat following lucerne/grass swards produced a higher grain yield than that red clover swards. Pre-crop of white clover and conventional drilling significantly affected winter wheat grain yield and the yield of triticale was higher following wheat after...

Effects of inter-varietal diversity, biotic stresses and environmental productivity on grain yield of spring barley variety mixtures
Provedor de dados: 21
Autores: Kiær, Lars P.; Skovgaard, Ib M.; Østergård, Hanne.
Varietal seed mixtures tend to increase and stabilize crop yields, yet their application is sparse. Large-scale cultivation of variety mixtures may require a better understanding of how inter-varietal interactions and their interaction with the environment may influence the grain yield of variety mixtures relative to their component varieties. For this purpose, six variety mixtures of spring barley and 14 component varieties were grown in each of 17 trial environments. A total of 28 observed and a priori plant characteristics, including grain yield, disease severity and weed competitiveness, were derived for each component variety in each trial. The relationship between inter-varietal diversity of each characteristic and the mixing effect on grain yield...

Can strip-cropping enhance pollination and fruit set in Hokkaido pumpkins?
Provedor de dados: 21
Autores: Johansen, Natasha H.; Dupont, Y.L.
The demand for organic vegetables is increasing rapidly but cannot be met by current agronomic methods. Alternative methods, which enhance biodiversity and ecosystem services including pollination, are currently under development. In SureVeg (a Core Organic Co-fund funded project), we tested strip-cropping systems, i.e. a diversified cropping system in which alternating rows of different vegetable crops are sown. It is hypothesized that strip-cropping will provide floral resources during an extended period, supporting agroecosystem services provided by beneficial insects, including natural biological control and insect pollination.  In the current study, we investigated a cropping system involving two insect pollinated crops: hokkaido pumpkin and faba...

P, K, Mg, S und N-Versorgung von Mischfruchtanbausystemen mit Ölpflanzen im ökologischen Landbau
Provedor de dados: 21
Autores: Paulsen, Hans Marten; Schochow, Martin.
Oil crops can be integrated in organic crop rotations in mixed cropping with other crops. The cropping system achieves only low oilseed yields but increases productivity per area in total yield. In theory soil nutrients in mixed cropping systems can be used more efficiently due to different root architecture and growing times of the plants. But even the nutrient demand should increase with higher productivity. In the study nutri¬ent content and uptake of seeds and straw of mixtures of winter rape with winter-barley, peas, or rye, of spring peas with spring rape, mustard or false flax, of blue lupine with safflower or false flax, of spring wheat with linseed or false flax and of linseed with false flax were screened. Productivity per area was increased in...

Was kostet der Zwischenfruchtanbau im Ökolandbau?
Provedor de dados: 21
Autores: Klöble, Ulrike; Grube, Jens; Sauer, Norbert.
Der Anbau von Zwischenfrüchten ist wirtschaftlich wertvoll in vielfältiger Hinsicht: Reine Marktfruchtbetriebe können die Humusbilanz aufbessern und mit Leguminosen Stickstoff in die Fruchtfolge einbringen. Für erosionsgefährdete Flächen wird eine Winterbegrünung möglich und Futterbaubetriebe können eine zusätzliche Futterfläche erschließen.    Ökonomisch lässt sich der Zwischenfruchtanbau nur schwer bewerten. Dies liegt u. a. daran, dass sich die Wirkungen auf den Boden, wie Humusbildung und Stickstoffnachlieferung, nur schwer quantifizieren lassen und somit der subjektiven Einschätzung des Landwirtes unterliegen. Je nach erwartetem Frischmasseertrag, veranschlagtem Futterwert und vermuteter Stickstoffnachlieferung zeichnet sich auf der Habenseite ein...

Root pruning reduces root competition in living mulch cropping systems
Provedor de dados: 21
Autores: Båth, B.; Kristensen, H.L.; Thorup-Kristensen, K.
In intercropping systems with a cash crop and a living mulch intercrop, competition between the cash crop and the intercrop (the living mulch) often reduces the yield of the cash crop. This project investigated (1) the influence of root pruning of living mulches on aboveground biomass of white cabbage. Below-ground growth and competition were examined by measuring (2) root distribution in minirhizotrons and (3) uptake of 15N placed at different soil depths. Two field experiments were carried out at the Aarslev Research Centre in Denmark.  These studies showed that the ability of mulch species to compete for resources at depth was restricted by pruning.

Grundwasserschutz im Organischen Landbau: Untersaaten in Kartoffeln zur Minderung hoher Restnitratmengen im Boden
Provedor de dados: 21
Autores: Haas, Guido.
Nach Kartoffeln werden hohe Nitratgehalte im Boden festgestellt. Um diese hohen Nitratgehalte zur und nach der Ernte im Boden organisch bewirtschafteter Kartoffeln zu mindern, wurden in den Jahren 1997 und 1998 verschiedene Arten für eine Untersaat in Feldversuchen auf dem Versuchsbetrieb Wiesengut sowie im Jahre 1999 zusätzlich auf drei weiteren Praxisbetrieben im Rheinland untersucht.  Untersaaten in Kartoffeln sind in organisch wirtschaftenden Betrieben in Anbauregionen mit regelmäßigem frühem Krautfäulebefall anbauwürdig. Für eine Untersaat vor Reihenschluß der Kartoffeln mit dem letzten Häufelgang (etwa Mitte Juni) eignen sich Sonnenblume und Mais. Diese Untersaaten wuchsen nach dem häufig im Juli einsetzenden Krautfäulebefall und raschem Absterben...

The effect of grasses grown for seed in mixture with legumes on the incidence of weeds and soil nitrogen content
Provedor de dados: 21
Autores: Cagas, Bohumir; Machac, Radek.
This report was presented at the UK Organic Research 2002 Conference on behalf of the Colloquium of Organic Researchers (COR).  The incidence of weeds and the content of soil nitrogen were investigated in the first year of a field trial with organic grass seed production in which the grasses were grown with companion legumes. Two grass species, timothy (Phleum pratense L.) cv. Sobol and perennial ryegrass (Lolium perenne L.) cv. Baca, were tested together with three legumes: red clover (Trifolium pratense L.) cv. Start, white clover (Trifolium repens L.) cv. Vysocan and black medick (Medicago lupulina L.) cv. Ekola. The N-nutrition and control of weeds were provided by three “ecological” methods and a conventional one (bacterial nodules of legumes, mulch,...

Effekte unterschiedlicher Systeme der Grundbodenbearbeitung  auf Erträge und Beikraut im Dauerfeldversuch Gladbacherhof
Provedor de dados: 21
Autores: Schulz, Franz; Brock, Christopher; Leithold, Günter.
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...

Influence of alleycropping microclimate on the performance of groundnut (Arachis hypogaea L.) and sesame (Sesamum indicum L.) in the semi-desert region of northern Sudan
Provedor de dados: 21
Autores: Shapo, Haider Elsafi; Adam, Hussien Suliman.
An alley cropping system was established at Hudieba Research Station (17.57’N and 33.8’ E) on a loamy sand soil of the semi-desert region of northern Sudan. The objective of this study was to investigate the influence of modified microclimate in 6-m wide alleys formed by Acacia ampliceps and Acacia stenophylla on growth and yield of groundnut. and sesame. Above-ground interactions were determined by measuring air temperature, relative humidity, wind speed, solar energy and shade length and behaviour. Groundnut and sesame were evaluated for growth and yield by laying out sample plots at southern, central and northern part of the alleys and at control plots. Due to microclimatic modifications in the alleys, the yield of both crops in the alleys significantly...

Buckwheat in the Nutrition of Livestock and Poultry
Provedor de dados: 21
Autores: Leiber, Florian.
With its high contents of starch, buckwheat grain can be a valuable source of carbohydrates in diets for any kind of livestock and poultry. Although the crude protein concentrations are limited, its amino acid profile is advantageous due to the high intrinsic proportions of lysine and methionine.  In many regions with temperate climate conditions it is possible to cultivate buckwheat as a catch crop, e.g. after the harvest of barley, in the same season. This makes the crop a second harvest from a given arable land within the same year. If it is used to feed livestock, it contributes to decrease the feed-food competition about arable surfaces in a world with dramatically growing food demands. As a flowering crop, buckwheat positively contributes to the...

Root Growth and Nitrogen Utilization of a Leek Crop and an Undersown Catch Crop
Provedor de dados: 21
Autores: Nielsen, Dr. Kai Lønne; Thorup-Kristensen, Dr. Kristian.
After its late harvest a leek (Allium porrum) crop will normally leave large quantities of nitrogen (N) in the soil which may be subject to leaching. A possible method to reduce N leaching losses is to establish a catch crop before the harvest of the leek crop. It was the aim of this study to investigate the effects of incorporating a catch crop in a leek crop with minimal competition and to monitor how root growth affected N availability across soil depths at different distances between catch and leek crop rows. To reduce competition between both crops leek was planted at 0.5 and 0.75 m row distances and chicory (Cichorium intybus) as a catch crop at an interrow spacing of 0.75 m. Minirhizotron glass tubes were inserted in the  middle of the interrow...

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.

Improvement of winter wheat baking quality in ecological cultivation by enlargement of row spacing and undersown intercrops
Provedor de dados: 21
Autores: Becker, Dr. Konstantin; Leithold, Prof. Dr. Günter.
Under ecological crop growing conditions, considerable problems consistently arise in fulfilling the baking quality of winter wheat demanded by consumers. The “wide row” procedure shows promising potential for effectively using the nutrient supply in ecological cultivation for the production of winter wheat with high baking performance. Increasing the distance between rows of winter wheat from 12.5 cm to 50 cm proved advantageous for the indirect quality parameters sedimentation value and gluten and crude protein concentration. Either no yield decreases or low decreases only up to 10% were noted. Because of an increased tendency to erode and in order to improve of the preceding crop’s value, creation of a green zone with legumes between the rows is...

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 if conventional and organic cropping systems, which differ clearly in strategies for nutrient and pest management, influence the harvest and sensory quality of the products?    Lettuce and onion were grown in a conventional and three organic vegetable cropping systems with different levels of external inputs and use of cover- and inter-crops for nutrient re-cycling and natural pest management in  the period of 2007-2009 (VegQure project). The crop rotation consisted of 8 fields of vegetables and cereals. Onion was grown after a year of oat and iceberg lettuce after winter rye. There were 3 replicates of each  cropping system each...

Optimierung des biologischen Gemüsebaus durch Gründüngung und Fruchtfolge
Provedor de dados: 21
Organic vegetable production is highly dependent on external nitrogen input. Frequently no manure is available, because this farm type is normally specialised and thus stockless. Consequently vegetable producers are subjected to crisis, related to severe animal diseases such as BSE.  To increase the nitrogen stocks on the farms, nitrogen fixing legumes are cultivated as green manure. However only parts of the knowledge gained in arable crops can be transferred to vegetable production systems. In this project, we investigate how to increase the benefits from a greenmanure through opimal cultivation techniques. Moreover we optimize rotations in crops which are harvested in late autumn such as cabbage or leek by undersowing greenmanure. Questions of nitrogen...

Modelling the ability of legumes to suppress weeds
Provedor de dados: 21
Autores: Storkey, Jonathan; Döring, Thomas F.; Baddeley, J. A.; Marshall, Athole; Roderick, S.; Jones, Hannah.
The ability of different legume cover crops to suppress annual weeds during the early establishment phase was compared using a simulation model of inter-plant competition and field observations. Height, partitioning parameters, extinction coefficients, crop density and time of emergence were recorded for 11 species sown in monocultures. A naturally occurring population of fat hen (Chenopodium album) was present on the experiment. The competition model was run to compare the expected suppressive ability of the different species on this weed. Samples of C. album were also taken from each plot immediately prior to cutting to provide some empirical observations. Predicted suppressive ability was correlated with seed size and height with large seeded, tall...

Autores: Baresel, Jörg Peter; Fischer, V.; van Hilten, S.; Charrois, A.; Köckeis, M.
Several non-legume species have been tested for their suitability as cover crops, especially as constituent of mixtures with common vetch (Vicia sativa) and subterranean clover (Trifolium subterrananeum) in field trials performed in southern Germany from 2013 to 2016. We present selected results. The highest amounts of biomass were produced by Glebionis segetum, Anethum graveolens and Borago officinalis, which were also able to compete with subterranean clover and common vetch. All other tested species produced less biomass than the two legume species and were outcompeted in mixtures.

Winter grazing as an alternative to mulching or mowing grass clover swards
Provedor de dados: 21
Autores: Westphal, M.Sc. Derk; Loges, Dr. Ralf; Taube, Prof. Dr. Friedhelm.
Management factors like the type of defoliation and seed mixture influence yield and forage quality of grass clover mixtures. In comparison to harvesting, grazing is less cost intensive. For economical reasons a maximum duration of grazing period is required. Grazing over winter can cause pasture damages. This problem is of minor relevance for grass clover grown on arable land in the last production year, which is ploughed in the following spring. This study compares different grass clover mixtures concerning yield, forage quality and suitability for winter grazing.With this background, tall fescue exerted more significant effect on the dry matter yield than perennial ryegrass. White clover showed significant superiority over all the other tested species,...

Modell zur Unterstützung strategischer und taktischer Fruchtfolgeplanung im Ökologischen Landbau
Provedor de dados: 21
Autores: Bachinger, J.; Zander, P.
Im Ökologischen Landbau gewinnt die Fruchtfolgegestaltung als wesentlicher Aspekt der strategischen und taktischen Planungsebene im Ackerbau durch den Verzicht auf externe Steuermechanismen gegenüber der operativen Planungsebene (z.B. Pflanzenschutzmitteleinsatz nach Prognosemodellen) an relativer Bedeutung. Deshalb ist die Entwicklung eines Entscheidungsunterstützungsmodells zur Fruchtfolge-Planung (für die Bereiche N-Versorgung, Beikrautregulierung, Berücksichtigung phytosanitärer Restriktionen) gerade zur Optimierung des ökologischen Landbaus sinnvoll.

Catch crops reduced nitrate leaching in both rotations at Jyndevad. The same tendency was seen in one rotation at Flakkebjerg. At Jyndevad, stubble cultivations decreased Elymus repens density in the treatments without catch crops. Application of manure decreased the E. repens density in one rotation. At Flakkebjerg, there was a lower infestation of C. arvense in the rotation with than without grass-clover, with least biomass in the crop the year after grass-clover. There was no significant difference between the biomass of C. arvense in the treatments with and without catch crop, in spite of the fact that stubble cultivations and row hoeing were carried out without catch crops. The reason was most likely that the nutrients retained in the topsoil by the...

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,...

Entwicklung der Humusgehalte und der Humusqualität   in verschiedenen Fruchtfolgen des ökologischen Landbaus
Provedor de dados: 21
Autores: Urbatzka, Peer; Beck, Robert.
A high turnover of Humus is one of the goals in organic farming. The effect of different crop rotations on the content and the quality of humus was examined in two long term field experiments in Bavaria, South Germany. 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 (33 and 40 %) and in the legume art (grass clover or grain legume). The soil samples were taken in 1998 (beginning of the trials), in 2010 and in 2013 and were analyzed for Corg and Nt.  The development of the Corg- and Nt-contents was better in the crop rotations with grass clover swards (increasing) than in the crop rotation with grain legume...

Anbau der Körnererbse in Mischkultur mit Gerste
Provedor de dados: 21
Autores: Klaiss, Matthias; Weidmann, Gilles; Siegrist, Franziska.
Körnererbsen (oder Eiweisserbsen) tolerieren leichte Bodenfröste und können daher im Gegensatz zu Soja auch in kühleren Regionen angebaut werden. Allerdings neigt diese Leguminosenart zur Lagerung, was zu Ertragsausfällen führen kann.  In diesem Praxistipp wird der Anbau von Körnererbsen in Mischkultur mit Gerste propagiert, indem er das dazu erforderliche Vorgehen von der Saatbettbereitung bis zur Ernte detailliert erläutert und Empfehlungen zur weiterführenden Fruchtfolgegestaltung liefert. Weiter regt der Praxistipp dazu an, die Methode durch einen Vergleich der Erntemengen von Rein- und Mischkultur zu testen.

Testing the sustainability of stockless arable organic farming on a fertile soil (OF0145)
Provedor de dados: 21
Autores: Cormack, W. F.
This is the final report of Defra project OF0145.  If organic farming is to expand in the arable east of England, where the knowledge, infrastructure and capital for livestock are not available, viable stockless systems will be needed. The aim is to maximise economic performance and in turn encourage conversion. Project OF0112 showed that a stockless arable rotation was consistently more profitable that a comparable conventional rotation on the fertile silty clay loam at ADAS Terrington. Project OF0145 researched challenges to sustaining that level of performance into the second crop rotation. The project was a combination of systems comparison, replicated experiments and monitoring of commercial farms.   The core of the project was an unreplicated systems...

N transfer in three-species grass-clover mixtures with chicory, ribwort plantain or caraway
Provedor de dados: 21
Autores: Dhamala, NR; Rasmussen, J; Carlsson, G; Søegaard, K; Eriksen, J.
Background and aims   There is substantial evidence that legume-derived Nitrogen (N) is transferred to neighboring non-legumes in grassland mixtures. However, there is sparse information about how deep rooted nonlegume forage herbs (forbs) influence N transfer in multi-species grasslands.  Methodology   Red clover (Trifolium pretense L.) was grown together with perennial ryegrass (Lolium perenne L.) and one of three forb species: chicory (Cichoriumintybus L.), ribwort plantain (Plantago lanceolata L.) or caraway (Carum carvi L.) in a field experiment. During the first year after the establishment, red clover leaves were labeled with 15N-urea to determine the N transfer from red clover to companion ryegrass and forbs.  Results   On an annual basis, up to 15...

Alternative forage crops for finishing lambs
Provedor de dados: 21
Autores: McLean, Barbara.
Alternative forage crops offer a number of benefits for farmers including a cheap finishing system for lambs, benefits for soil condition, fertility building for rotations and providing a cover crop. Certain forages have also been demonstrated to have some anthelmintic benefits for lambs. A demonstration study was undertaken to investigate the potential of six crops used in the horticulture industry (fertility building crops) as forage crops for weaned growing lambs. The crops include white mustard, Nemat (form of Rocket), Crimson Clover, Sweet Clover , Caliente 119 and Caliente 99 (Cruciferae). The grazing field was split into three blocks and two crops were sown in solid strips in each block. Each block also had grass headlands. 10 ewe lambs were...

Autores: Eriksen, J.; Søegaard, K.; Askegaard, M.
In white clover/ryegrass mixtures grazing in one year significantly increases the yield in the next, compared to cutting. Red clover is a good supplement to the mixture as it performs well under cutting regime, while white clover takes over during grazing. Overall, inclusion of red clover in the mixture contributes to a more robust sward and  increased flexibility in utilization

Autores: Döring, Thomas F.; Crowley, Oliver; Pearce, Helen; Storkey, Jonathan; Brown, Rob; Jones, Hannah.
The inter-relationship between food production and biodiversity is now well established. The ecosystem services provided by the organisms within the environment include, for example, nutrient cycling, pest regulation and pollination, to name but a few. However, perhaps the greatest challenge now facing agricultural production is to find ways of enhancing these ecosystem services, while at the same time increasing food production – particularly in light of food security issues. A range of farm and landscape management options include ‘setting aside’ land for wildlife. However, some proponents argue that such land should be used for food production. While the debate continues, there is no doubt that a large body of scientific evidence from the last three...

Autores: Matos, Eduardo da Silva; Mendonça, Eduardo de Sá; Lima, Paulo César de; Coelho, Marino Salgarello; Mateus, Renato Faria; Cardoso, Irene Maria.
The use of green manure may contribute to reduce soil erosion and increase the soil organic matter content and N availability in coffee plantations in the Zona da Mata, State of Minas Gerais, in Southeastern Brazil. The potential of four legumes (A. pintoi, C. mucunoides, S. aterrimum and S. guianensis)to produce above-ground  biomass, accumulate nutrients and mineralize N was studied in two coffee plantations of subsistence farmers under different climate conditions. The biomass production of C. mucunoides was influenced by the shade of the coffee plantation.C. mucunoides tended to mineralize more N than the other legumes due to the low polyphenol content and polyphenol/N ratio. In the first year, the crop establishment of A. pintoi in the area took...

Short-term residual N unaffected by forbs in grass-clover mixtures
Provedor de dados: 21
Autores: Dhamala, NR; Rasmussen, J; Cong, WF; Carlsson, G; Søegaard, K; Eriksen, J.
We determined the effect on residual nitrogen (N) of including forbs (chicory, ribwort plantain and caraway) in perennial ryegrass-red clover mixtures. Although soil N inputs during the grassland phase differed markedly between mixtures, in a pot experiment we found no differences in the potentially mineralizable N of the soil or in the dry matter production and N content of the spring barley test crop. The fertilizer value of the grassland mixtures corresponded to 10 g N/m2, irrespective of forb inclusion. Thus, the inclusion of nonlegume forbs did not negatively affect short-term residual N fertility of legume-based grasslands.

Öko-Kartoffeln genießen bei den Verbrauchern eine hohe Beliebtheit. Gleichzeitig steigen die Anforderungen an die Qualität. Qualität ist ein komplexer Begriff und beinhaltet zum einen die „äußere Qualität“. Bei Kartoffeln zum Beispiel zählen hierzu eine gleichmäßige Knollenform, keine Beschädigungen sowie eine möglichst glatte Schale ohne schwarze Rhizoctonia-Pocken oder Schorfflecken. Zur „inneren Qualität“ zählen dagegen die wertgebenden und wertmindernden Inhaltsstoffe. Dazu zählen ein der Sorte entsprechender Stärkegehalt, ein geringer Nitratgehalt und eine hohe sensorische Qualität, womit u.a. das Geschmackserlebnis gemeint ist. Geschmack ist hier definiert als der Gesamtsinneseindruck, den der Verbraucher durch das Zusammenwirken von Geschmacks-,...

In ökologisch bewirtschafteten Systemen ist Stickstoff häufig der begrenzende Wachstumsfaktor. Daher stehen Bemühungen um seine effektive Nutzung innerhalb der Fruchtfolge im Mittelpunkt vieler Untersuchungen. Diese Problematik ist besonders auf humusschwachen Sandstandorten Nordostdeutschlands von Bedeutung. Je sandiger der Boden desto geringer ist sein Wasser- und Nährstoffspeichervermögen. In der Folge steigt die Gefahr der Nährstoffauswaschung, was insbesondere den Stickstoff betrifft. Einerseits geht dem Betriebskreislauf dadurch Stickstoff verloren, andererseits erfolgt ein verstärkter Eintrag in den Wasserkreislauf.

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.

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...

Improving fertility management and weed control in sustainable lupin production in the UK (LISA)
Provedor de dados: 21
UK agriculture is faced with the need to reduce diffuse pollution, particularly of nitrogen (N) and phosphorus (P), whilst remaining economically viable. Spring lupins can provide a high protein grain of known provenance and source of oils and balanced energy for optimised ruminant and non ruminant livestock production. They have the potential to increase the efficiency of N and P use in arable rotations and in mixed arable livestock systems. This five year project is the first comprehensive evaluation of the benefits and disbenefits of this crop for organic and conventional use in the UK. Comparisons with other grain legumes will analyse on farm nutrient budgets, feed utilisation, emissions from animal wastes and agronomic factors. Molecular markers for...

Carbon footprints of crops from organic and conventional arable crop rotations – using a life cycle assessment approach
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Meyer-Aurich, Andreas; Olesen, Jørgen E.; Chirinda, N.; Hermansen, J.E.
Many current organic arable agriculture systems are challenged by a dependency on imported livestock manure from conventional agriculture. At the same time organic agriculture aims at being climate friendly. A life cycle assessment is used in this paper to compare the carbon footprints of different organic arable crop rotations with different sources of N supply. Data from long-term field experiments at three different locations in Denmark were used to analyse three different organic cropping systems (‘Slurry’, ‘Biogas’ and ‘Mulching’), one conventional cropping system (‘Conventional’) and a “No input” system as reference systems. The ‘Slurry’ and ‘Conventional’ rotations received slurry and mineral fertilizer, respectively, whereas the ‘No input’ was...

Leaching of NO3− from vegetable cropping systems can be very high compared to arable systems. This is a problem for vegetable growers in general as it decreases groundwater quality, and for organic growers in particular as the organic production is often limited by N. In a field experiment, we investigated the N uptake and root growth of three vegetables using minirhizotrons reaching 2.4 m with the purpose to study the relationship between vegetable root distribution and uptake of NO3− from deep soil layers. NO3− uptake was studied over a 6 d period at the end of September by injection of 15 NO3− at four depths in the ranges: 0.2–0.8, 0.6–1.8, and 1–2.5 m under late sweet corn (Zea mays L. convar.

In a variety mixture, competition between component varieties as well as differences in performance of the components may lead to changes in the proportion of component varieties between seed sown and seed harvested. This will imply that farm saved seeds of variety mixtures will constitute an evolving population. How much changes are found over a short period of years and in different environments?  In 2002, six 3-component variety mixtures of spring barley were constructed based on altogether 14 mostly high-yielding varieties. The six mixtures and derivatives of these were included in the large Danish BAR-OF variety trials in the years 2002-2005 (Østergård et al. 2005).

The contribution of grass and clover root turnover to N leaching
Provedor de dados: 21
Autores: Rasmussen, Jesper; Helgadóttir, Á.; Frankow-Lindberg, B.; Loges, R.; Eriksen, J.
Sources of inorganic and organic N leaching from grass-clover mixtures at field sites in Denmark, Germany and Iceland were investigated. Grass or clover was labelled with 15N-urea four times (autumn 2007, spring, summer and autumn 2008) prior to the leaching season in autumn and winter 2008. Soil water was sampled at 30 cm depth and analyzed for 15N-enrichment of dissolved inorganic N (DIN) and dissolved organic N (DON). Most 15N was recovered in DON for both labelled grass and clover at all sites. At the Danish site, grass and clover contributed more to the DON pool than the DIN whereas the opposite was observed at the German and Icelandic sites. The results show that both clover and grass contribute directly to N leaching from the root zone in mixtures,...

Soil erosion potential of organic versus conventional farming evaluated by USLE modelling of cropping statistics for agricultural districts in Bavaria
Provedor de dados: 21
Autores: Auerswald, Karl; Kainz, Max; Fiener, Peter.
Organic agriculture (OA) aims to identify a production regime that causes less environmental problems than conventional agriculture (CA). We examined whether the two systems differ in their susceptibility to soil erosion by water. To account for the large heterogeneity within the rotations practised on different farms, we chose a statistical evaluation which modelled erosion using the USLE method from the cropping statistics for 2056 districts in Bavaria (70 547 km2; 29.8% arable). Physical conditions of erosion  were determined in a rectangular grid yielding 13 125 grid-cells of c. 5 km2 each. For validation, erosion was measured in 10 sub-watersheds on two neighbouring OA and CA farms over 8 years (287 erosive events). On average, about 15% less erosion...

Weed management in cereals with cover crops - do they help of hinder?
Provedor de dados: 21
Autores: Salonen, Jukka.
Sustainable crop production calls for integrated weed management approaches. Cover crops (CCs) have been studied primarily in the context of soil fertility and soil structure but they might also supplement the weed management toolbox, particularly when adapted to long-term control strategies. The challenge in organic cropping is to provide strong weed suppression without severely compromising weed species diversity and crop yields. Several CC species, mainly sown in mixtures, were studied in organically cropped 3-year field experiments in southern Finland. The study was part of the PRODIVA project (Core Organic Plus 2015-2018) in which crop diversification for better weed management has been studied and presented in the 18th EWRS Symposium.

Annual self-reseeding legumes and their application into Mediterranean Organic cropping systems
Provedor de dados: 21
Autores: Driouech, Noureddin.
Self-reseeding winter annual legumes are an essential component of the Mediterranean natural resources. 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...

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.

Autores: Nurk, Liina; Graß, Rüdiger; Hubert, Sabine; Pekrun, Carola; Wachendorf, Michael.
Im Ökologischen Landbau besteht ein steigendes Interesse am Silomaisanbau als wertvolles Futter in der Rinderfütterung bzw.als Substrat zur Verwertung in Biogasanlgen. Herkömmliche Maisanbausysteme verursachen oft Umwelt- und Anbauprobleme wie Bodenerosion, Unkrautkontrolle, mangelnde Nährstoffversorgung. Zur Reduzierung dieser Problematik wird seit 2013 in einem Feldversuch der Mischanbau von Silomais mit Stangenbohnen (Phaseolus vugaris) an der Universität Kassel-Witzenhausen untersucht. Die Ergebnisse des ersten Versuchsjahres erbrachten geringere Erträge der Mischanbauvarianten im Vergleich zum reinen Silomaisanbau. Die verwendete Bohnensorte war zur Silageernte im Herbst bereits zu weit abgereift und große Anteile der Biomasse war abgestorben bzw....

Viehhaltung im Ökologischen Landbau - ja oder nein?  Effekte auf Bodenfruchtbarkeit, N-Bilanzen und Erträge
Provedor de dados: 21
Autores: Schulz, Franz; Brock, Christopher; Leithold, Günter.
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 farm types (with and without lifestock raising) combined with tillage treat-ments on plants, soil and environment have been investigated. This article presents results on soil fertility, N-balances and cash crop yields according to the farm system. All in all, the superiority of a management system with cattle over stockless organic farming is demonstrated. The mixed farm type led to higher amounts of humus in the soil, lower N-losses and higher yields. Unless stockless farming cannot be avoided a mulched grass-legume ley, in combination with grain- and fodder legumes as main or...

INTRODUCING TREES IN DAIRY AND POULTRY FARMS - Experiences dairy and poultry farmers' networks in The Netherlands
Provedor de dados: 21
Autores: Bestman, Monique; Eekeren, Nick van; Luske, Boki; Vonk, Mark; Anssems, Emiel; Boosten, Martijn; Bree, Miriam van.
In the Netherlands networks of goat, cow and poultry farmers started to grow trees in their fields and outdoor runs. This was done for different reasons: animal welfare (shelter); production of fodder, biomass, litter or fruits; spread of minerals from manure; increase biodiversity; keep away certain wild animals that carry diseases. In this abstract we present the project activities and the first experiences from the farmers. The so-called ‘silvopastoral’ systems (= combination of trees and animals) are applied traditionally already long times in Africa and Mediterranean countries. Now we apply them in modern, relatively high input animal husbandry systems.

Designing cover crop mixtures to enhance potential weed suppression in organic no-till vegetable systems
Provedor de dados: 21
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...

Autores: Hauggaard-Nielsen, Henrik; Andersen, Mette Klindt; Joernsgaard, Bjarne; Jensen, Erik Steen.
Intercropping advantages may be influenced by both plant density and relative frequency of the intercrop components. In a field study barley (Hordeum vulgare L.) and pea (Pisum sativum L.) were sole cropped and intercropped at three densities, corresponding to i) half of the recommended, ii) the recommended and iii) twice the recommended plant density. Two intercrops combinations were included holding 1/3pea+2/3barley and 2/3pea+1/3barley relative to the sole crop densities employed.   For three growth intervals within the whole growing period, the relative performance and interactions between the two crops were assessed using the Relative Efficiency Index (REIc). The relative performance of the two species varied over the growing season and was influenced...

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.

Perennial weeds in organic arable farming – challenges &amp; dilemmas
Provedor de dados: 21
Autores: Rasmussen, I.A.; Askegaard, M.; Olesen, J.E.
Long-term control of perennial weeds create a challenge in organic farming, especially in ar-able farming. Perennial weeds are most often controlled by tillage, often stubble tillage after harvest of cereals or short-term tillage during the summer (Melander et al., 2005). Tillage leads to increased leaching of nutrients (Askegaard et al., 2005), which is unacceptable for the environment and in turn renders the succeeding crop less competitive compared to the peren-nial weeds – thus initiating a vicious circle.

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).

Reduced tillage in temperate organic farming: implications for crop management and forage production
Provedor de dados: 21
Autores: Krauss, Maike; Berner, Alfred; Burger, Dieter; Wiemken, Andres; Niggli, Urs; Mäder, Paul.
To promote conservation tillage in organic farming systems, weed control and ley removal within arable-ley rotations need to be optimized. A long-term field trial was thus established in Frick, Switzerland in 2002 on a clayey soil and with a mean precipitation of 1000 mm⁄ year. The tillage experiment distinguished between conventional tillage with mouldboard ploughing (CT, 15 cm depth) and reduced tillage (RT), including a chisel plough (15 cm) and a stubble cleaner (5 cm). Results of a 2-year grass-clover ley (2006 ⁄ 2007) and silage maize (2008) are presented. Due to dry conditions, mean grass-clover yields were 25% higher in RT than in CT, indicating better water retention of RT soils. Clover cover and mineral contents of the fodder mixture were also...

Nitrogen fixation in red clover grown in multi-species mixtures with ryegrass, chicory, plantain and caraway
Provedor de dados: 21
Autores: Dhamala, NR; Rasmussen, J; Carlsson, G; Søegaard, K; Eriksen, J.
While many studies have investigated effects of species composition and management on N2-fixation dynamics in simple clover-grass mixtures, there is a lack of knowledge about the performance of legumes and their N2-fixation in more species-rich grassland including non-legume forbs. This study investigated N2-fixation and total N yield in grassland mixtures including different combinations of red clover, perennial ryegrass and three deep rooted forbs: chicory, ribwort plantain and caraway, managed without and with slurry application. The percentage of clover N derived from atmosphere (%Ndfa) increased in mixtures, but was unaffected by inclusion of forbs. However, forbs affected the quantity of N2-fixation and total N yield by affecting the red clover...

Autores: Schneider, Monika; Andres, Christian; Trujillo, German; Alcon, Freddy; Amurrio, Patricia; Seidel, Renate; Weibel, Franco; Milz, Joachim.
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.  The Research Institute of Organic Agriculture (FiBL) is pioneering to fill this...

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 semi-natural grasslands, plant diversity has shown to correlate with increased primary production and reduced weed invasion. If such positive effects also apply to low input agricultural grasslands, the resource-use efficiency could be improved.   To investigate whether other grassland species and diverse grassland mixtures could be more productive, a grassland on a shallow sandy soil in the south of the Netherlands was sown in April 2009 with seven non-leguminous grassland mixtures. Though some sown species vanished quickly, diverse mixtures proved less susceptible for invading species three years after sowing (p&lt;0.05). Yields in 2010 and 2011 were 11% higher for mixtures with two functional groups of grassland species compared with mixtures with...

Biogas potential from forbs and grass-clover mixture with the application of near infrared spectroscopy
Provedor de dados: 21
Autores: Wahid, R; Ward, AJ; Møller, HB; Søegaard, K; Eriksen, J.
This study investigated the potentials of forbs; caraway, chicory, red clover and ribwort plantain as substrates for biogas production. One-, two- and four-cut systems were implemented and the influence on dry matter yields, chemical compositions and methane yields were examined. The two- and four-cut systems resulted in higher dry matter yields (kg [total solid, TS] ha-1) compared to the one-cut system. The effect of plant compositions on biogas potentials was not evident. Cumulative methane yields (LCH4 kg-1 [volatile solid, VS]) were varied from 279 to 321 (chicory), 279 to 323 (caraway), 273 to 296 (ribwort plantain), 263 to 328 (red clover) and 320 to 352 (grass-clover mixture), respectively. Methane yield was modelled by modified Gompertz equation...

Neue Anbaustrategien zur Erhöhung der N-Effizenz und zur Reduzierung des Unkrautdruckes im ökologischen Landbau
Provedor de dados: 21
Ein großes Problem des ökologischen Landbaus stellt sich in der meist nicht bedarfsgerechten Stickstoffversorgung der Betriebe dar. Dies schlägt sich sowohl auf den Ertrag als auch auf die Qualität der angebauten Produkte nieder. Um dieses Hemmnis zu überwinden, soll zum einen für den Bereich der Winterungen das N-Angebot des Bodens erhöht werden, indem eine zusätzliche Stickstoffzufuhr über die Ansaat von abfrierenden Körnerleguminosen als Beisaat in vorzeitig ausgesätem Wintergetreide erfolgt. Zum anderen soll für den Bereich der Sommerungen eine Reduktion der Nitratverluste durch den Anbau von Grasuntersaaten sowie spätere Aussaattermine von Wintergetreide erzielt werden. Ziel des Projektes ist es insofern, die Anbauverfahren für Wintergetreide,...

Roots below one meters depth are important for nitrate uptake by annual crops
Provedor de dados: 21
Autores: Kristensen, Hanne L.; Thorup-Kristensen, Kristian.
The root depths of annual crops vary from 0.2 m to more than 2 m depending on root growth rate and length of growing season. However, studies of root growth and N uptake are often restricted to a depth of 1 m or less, as root biomass is assumed to be negligible below this depth. We have studied the importance of root growth and N uptake to a depth of 2.5 m in fully grown field vegetables and cover crops by use of minirhizotrons and deep point placement of 15N. Deep rooted crucifereous crops were found to have high root densities to a depth of 1.5-2 m and high 15N uptake to this depth. Uptake was significant near the bottom of the root zone at a depth of 2-2.5 m where root density was low. Here N uptake rates were higher per unit root length compared to...

Data on the potential of catch crops to reduce soil nitrate contents, on their N accumulation and biological nitrogen fixation (BNF) are lacking for organic farming in the dry, pannonic region of Eastern Austria. The effect of legume, non-legume, and legume + non-legume crops used as catch crops on inorganic soil nitrogen, crop biomass and crop N, and BNF were tested in comparison to bare fallow. Non-legumes and legumes + non-legumes were more efficient than legumes in reducing inorganic soil N contents in autumn and nitrate contents in soil solution from the subsoil in winter. This reduction in inorganic soil N did not last until March of the following year due to N mineralisation from the mulch. The legume + non-legume mixture contained a larger amount...

Performance of multi-species grassland mixtures. Mineral accumulation, nitrogen transfer and nitrogen uptake
Provedor de dados: 21
Autores: Pirhofer-Walzl, Karin.
This thesis is located within the framework of research on temperate agricultural grasslands. Plant diversity in temperate agricultural grasslands is impoverished today. Many conventional grasslands in Europe consist of simple grass mixtures, sometimes monocultures. Organic and increasingly conventional grasslands are sown as mixtures of grasses and legumes and from time to time as multi-species mixtures that include forage herbs. Temporary grasslands are regularly resown or incorporated in a crop rotation and produce ruminant fodder. Some studies indicate that various forage herbs have traits that may complement grass-legume mixtures; among others, increased macro- and micromineral concentration. Hence multi-species grassland mixtures, comprising grasses,...

Prodiva project - Crop species mixtures for weed suppression
Provedor de dados: 21
Autores: Verwijst, Theo; Lundkvist, Anneli; Krawczyk, Roman; Kaczmarek, Sylvia.
The aim of this study is to assess the weed suppressive ability of crop mixtures and impact of weeds on crop yield as a function of species and densities by means of field experiments and controlled experiments with mixtures of barley and pea, conducted in Sweden and Poland. The performance of crop mixtures was compared to the performance of pure crops with regard to their ability to suppress weeds. In the fields, natural weed populations were used while the controlled experiments employed Elytrigia repens or Sinapis alba as a model weed.     Preliminary results from the controlled experiment in Sweden showed that the presence of a crop (sole crop or intercrop) significantly diminished the growth of E. repens. The ability to compete was lower in peas,...

Målet med stribedyrkning er større udbyttestabilitet med fokus på forebyggelse af næringsstoftab og jorderosion, samt reduceret angreb af sygdomme og skadedyr.  Stribedykning er en metode til produktion af fødevarer og  biomasse til energiformål, hvor der tages højde for eventuelle negative effekter på jordens frugtbarhed. Det er et forsøg på i større grad at drage nytte af afgrødediversitet i økologiske sædskifter. Kombinationen af enårige og flerårige afgrøder på samme mark i et stribedyrkningssystem giver mulighed for at øge diversiteten i de nuværende sædskifter. Det vi undersøger er, om økologiske systemer kan vinde ved at øge diversiteten på den enkelte mark ved at introducere afgrøder i striber. Derudover kan markernes topografi og form måske...

Simulating Soil Organic Matter Transformations with the New Implementation of the Daisy Model
Provedor de dados: 21
Autores: Petersen, Anders; Bruun, Sander; Jensen, Dr. Lars Stoumann; Hansen, Dr. Søren.
Daisy is a well-tested deterministic, dynamic soil-plant-atmosphere model, capable of simulating water balance, nitrogen balance and losses, development in soil organic matter and crop growth and production in crop rotations under alternate management strategies. Originally it was developed as a system of single models describing each process involved, but recently it has been developed into a framework, which can be used for implementation of several different models of each of the different processes. Thus, for example a number of different models for simulating soil water dynamics can be chosen depending on the purpose of the simulation and the availability of data for parameterisation.   The sub-model simulating soil organic matter is still a fixed...

Forage herbs improve mineral composition of grassland herbage
Provedor de dados: 21
Autores: Pirhofer-Walzl , K.; Søegaard, Karen; Høgh-Jensen, Henning; Eriksen, Jørgen; Sanderson, M.A.; Rasmussen , Jim; Rasmussen, Jesper.
Provision of an adequate mineral supply in the diets of  ruminants fed mainly on grassland herbage can present a challenge if mineral concentrations are suboptimal for animal nutrition. Forage herbs may be included in grassland seed mixtures to improve herbage mineral content, although there is limited information about mineral concentrations in forage herbs. To determine whether herbs have greater macro- and micromineral concentrations than forage legumes and grasses, we conducted a 2-year experiment on a loamy-sand site in Denmark sown with a multi-species mixture comprised of three functional groups (grasses, legumes and herbs). Herb species included chicory (Cichorium intybus L.), plantain (Plantago lanceolata L.), caraway (Carum carvi L.) and salad...

Repeated use of green-manure catch crops in organic cereal  production - grain yields and nitrogen supply
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Henriksen, Trond Maukon; Eltun, Ragnar; Sjursen, Helge.
By restricted access to manure, nitrogen (N) supply in organic agriculture relies on biological N-fixation. This study compares grain yields after one full-season green manure (FSGM) to yields with repeated use of a green-manure catch crop. At two sites in south-eastern Norway, in a simple 4-year rotation (oats/wheat/oats/wheat), the repeated use of ryegrass, clover, or a mixture of ryegrass and clover as catch crops was compared with an FSGM established as a catch crop in year 1. The FSGM treatments had no subsequent catch crops. In year 5, the final residual effects were measured in barley.    The yield levels were about equal for grains with no catch crop and a ryegrass catch crop. On average, the green-manure catch crops increased subsequent cereal...

The effect of different management strategies on growth, composition and nutrient up¬take of a cover crop mixture of summer vetch and oil radish were tested in field ex¬pe¬ri¬ments on the Research Station Gladbacherhof. Slurry application and cereal straw management (incorporation vs. harvesting) affected composition of cover crop signifi-cantly: slurry application decreased legume content and biological N2-fixation signifi-cantly. By this way the N-input in farm cycle were reduced. The higher the amount of straw residues were left on field, the higher the legume content was in the cover crop mixture. High legume content in cover crop mixtures not only increased N2-fixation, but also P uptake of the cover crop. According to available literature...

Use of competitive crops to reduce Cirsium arvense
Provedor de dados: 21
Autores: Rasmussen, I.A.
Cirsium arvense is difficult to control and mechanical control may result in yield loss or nutrient leaching. Growing a competitive crop such as grass clover has earlier been seen to reduce the infestation. This paper describes a test of different competitive crops (oilseed rape and fibre hemp) comparing the infestation with that occurring with one or two years of grass clover. Oilseed rape did not grow well and was not very competitive, while C. arvense infestation was reduced the year after growing fibre hemp or grass-clover.

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...

I økologisk jordbrug anvendes alsidige sædskifter, efterafgrøder og/eller tildeling af husdyrgødning/halm/kompost. Alt dette er med til at fremme mængden af organisk stof i jorden, som normalt forventes at spille en stor rolle for strukturen og poresystemet (jordens hulrum).

De langvarige forsøg med forskellig gødskning på Askov Forsøgsstation giver et godt grundlag for at vurdere effekten af organisk stof på jordens poresystem. Ca. 100 års forsøg uden tilførsel af nogen form for gødning har resulteret i et indhold af organisk stof i jorden på kun ca. 1% (svarende til et humusindhold på ca. 1,7%).

Variability of herbage production in mixed leys as related to ley age and environmental factors: a farm survey
Provedor de dados: 21
Autores: Riesinger, Paul; Herzon, Irina.
Influences of ley age, soil properties, and geographical location on the herbage production of red clover-grass leys were determined under practical conditions on 27 organic farms located in the southern and in the northwestern coastal regions of Finland. Averaged over one-, two-, and three-year-old leys the accumulated first and second cuts produced 7.12 t dry matter herbage ha-1 year-1, with a clover proportion of 34.8%. Herbage production declined with increasing ley age. The average proportion of clover increased from 26.4% in the first to 43.7% in the second cut but decreased with ley age. Within- and between-field variations of clover proportions markedly decreased from the first to the second cut and strongly increased with ley age, while changes in...

Simulating root density dynamics and nitrogen uptake in the soil profile – A simple approach
Provedor de dados: 21
Autores: Pedersen, Anders; Zhang, Kefeng; Thorup-Kristensen, Kristian; Jensen, Lars S.
We present a 2-D model for simulation of root density and nitrogen (N) uptake for crops grown in agricultural systems, based on a modification of Gerwitz and Page’s root density calculation. A root system form parameter was used to describe the distribution of root biomass vertically and horizontal in the soil profile. The form parameter can vary from 0 where root density is evenly distributed in the soil profile, to 8 where practically all roots are found near the surface. Additionally, the root model has other components describing root features, such as specific root length, N uptake kinetics.   The root penetration rate and the depth distribution of root density were found to be the most important parameters controlling crop N uptake from deeper soil...

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.

Die in den vergangenen Jahren deutliche Ausweitung der Anbaufläche des Ökologischen Landbaus führte in der Praxis zu Wissenslücken bzgl. der Besonderheiten des Ökologischen Anbaus. Vor allem ein adäquates Fruchtfolge-Management hat sich als schwierig erwiesen. Optimale Fruchtfolgen sollten eine ausreichende Stickstoffversorgung aller Fruchtfolgeglieder sichern und gleichzeitig phytosanitäre Restriktionen, eine ausreichende Unterdrückung von Unkräutern und gesamtbetriebliche Anforderungen wie die Bereitstellung von Futter und die Verwertung von Wirtschaftsdünger berücksichtigen.

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,...

Red clover grown in a mixture with grasses: yield, persistence and dynamics of quality characteristics
Provedor de dados: 21
Autores: Mela, Timo.
Red clover (Trifolium pratense L.) was grown in mixtures with timothy and meadow fescue in field experiments at four sites in Finland to broaden knowledge on its potential as a forage crop. The effects of cutting frequency, nitrogen fertilization in the spring and sward density were investigated. Forage yield quality was analyzed using standard methods. Red clover produced well in all swards during the two first seasons. In the third summer the proportion of red clover was greatly diminished except on sandy soil at the northernmost locality (64°40'N) where it remained productive. Linear regression adequately described the dependence of crude fibre content and crude protein content in dry matter of the primary growth and regrowth, both of red clover and...

Leguminous cover crops: an important tool for improving resource use efficiency in organic arable cropping systems
Provedor de dados: 21
Autores: ANTICHI, DR. D.; MAZZONCINI, PROF. M.; BARBERI, PROF. P.; BIGONGIALI, DR. F.; CARPI, DR. G.
Cover crops are one of the most effective tools for organic farmers to improve the efficiency of their agro-ecosystems, while also reducing economic costs and environmental problems. The choice and usefulness of a cover crop species strictly depend on its adaptability to specific climate and soil conditions, but also on its relationships with other species (crops and weeds) and on the quality of farm management. Nine different pure species and three species mixtures were cultivated for two years as winter cover crops in a rainfed stockless arable organic cropping system as part of the MASCOT long-term experiment. Leguminous cover crops showed the highest level of biomass production in both years. Hairy vetch (Vicia villosa), either in pure stand or in...

Stickstoffflüsse in verschiedenen Fruchtfolgen des ökologischen Landbaus – Ergebnisse aus dem CONBALE-Projekt Lindhof
Provedor de dados: 21
Autores: Ruhe, Iris; Loges, R.; Taube, F.
Problemstellung/Ziele:  Stickstoff (N) stellt bei ökologischer Bewirtschaftung von viehlosen Betrieben den ertragsbegrenzenden Faktor dar. Der N-Versorgungsgrad eines Betriebes wird im wesentlichen durch den Leguminosenanteil in der Fruchtfolge bestimmt. Hierbei beeinflusst vor allem die Nutzung der Leguminosen (als Gründüngung, Silagegewinnung, Körnerleguminose oder Zwischenfrucht) den N-Input. Die Optimierung der N2-Fixierungsleistung der Leguminosen und ein möglichst geschlossener N-Kreislauf im Betrieb bilden die Grundlage des N-Managements. N-Verluste in Form von Nitratauswaschung führen neben dem Verlust des wichtigsten Produktionsfaktors (Stickstoff)auch zu einer Belastung des Grundwassers bzw. anderer Ökosysteme.

Intercropping wheat with pea for improved wheat baking quality
Provedor de dados: 21
Autores: Hauggaard-nielsen, Henrik; Trydeman Knudsen, Marie; Ravn Jørgensen, Johannes; Steen Jensen, Erik.
Field pea (Pisum sativum L.) and wheat (Triticum sativum L.) were either sole cropped or intercropped in a complete design of five relative proportions and five density levels to determine the effects of interspecific interaction in an intercrop on wheat baking quality. It is shown how pea interspecific competitive ability for factors such as light and water results in an increase in wheat protein content without reducing other important quality parameters. Density and relative crop frequency can be used as “regulators” when specific objectives such as bread making quality are wanted

Intercropping grain peas with barley
Provedor de dados: 21
Autores: Alföldi, Thomas; Clerc, Maurice; Stöcklin, Milo.
Intercropping of legumes with cereals is a promising possibility to produce fodder protein while creating few costs and using few resources.    Practicable cultivation methods of intercropping with protein peas/barley and field beans/oats were developed, both with mixing ratios of 80% and 40%, respectively, of the usual local seeding amount for the single crop (possible for winter crops as well as for spring crops).     The grain serves as a support crop, suppresses weeds and provides a risk coverage in years of poor grain legume development.    Since 2010, the acreage of organic peas and beans, mostly grown in mixed cultures, has multiplied.     This increase was also possible due to mills that buy and separate the yield of intercropping systems into its...

De mængder af organisk stof, man påvirker med almindelig landbrugsdrift, har ikke nævneværdig indflydelse på jordens vandholdende evne. Anvendelse af husdyrgødning i stedet for mineralsk gødning kan heller ikke forventes at påvirke jordens ledningsevne for vand i pløjelaget. Et højt næringsstofniveau giver – formodentlig pga bedre rodvækst – flere store porer og bedre ledningsevne for vand i jordlaget under pløjedybde. Effekten er uafhængig af, om næringsstofferne er tildelt som husdyrgødning eller som mineralsk gødning.

Soil aggregation – a matter of proper management
Provedor de dados: 21
Autores: Elmholt, S.; Schjønning, P.; Munkholm, L.J.
Soil crumbs are important to soil functions. These include plant growth, and the growth of fungi and bacteria forming agents for binding and bonding of new crumbs. We have studied how commercial organic and conventional farming affect this interaction. A diverse crop rotation, including grass, and animal manure resulted in stable crumbs with a high content of biological binding and bonding agents. A cash crop rotation with the addition of only synthetic fertilizers resulted in small, stable aggregates – more like clods - with clay as binding agent. Such a soil will provide poor conditions for preparing seedbeds, because prolonged rain makes it soft and muddy while drought makes it hard as brick.

Grain yield increase in cereal variety mixtures: A meta-analysis of field trials
Provedor de dados: 21
Autores: Kiær, Lars P.; Skovgaard, Ib; Østergård, Hanne.
Plant ecology theory predicts that growing seed mixtures of varieties (variety mixtures) may increase grain yields compared to the average of component varieties in pure stands. Published results from field trials of cereal variety mixtures demonstrate, however, both positive and negative effects on grain yield. To investigate the prevalence and preconditions for positive mixing effects, reported grain yields of variety mixtures and pure variety stands were obtained from previously published variety trials, converted into relative mixing effects and combined using meta-analysis. Furthermore, available information on varieties, mixtures and growing conditions was used as independent variables in a series of meta-regressions. Twenty-six published studies,...

Die vielen Facetten von Zwischenfrüchten
Provedor de dados: 21
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...

Effect of individual grass species and grass species mixtures on soil quality as related to root biomass and grass yield
Provedor de dados: 21
Autores: Eekeren, Nick J.M.; Bos, Merijn M.; Wit, J. de; Keidel, H.; Bloem, J.
For the purpose of feeding value, drought resistance and nitrogen utilization, other grasses (e.g. Festuca arundinacea and Dactylis glomerata) than the currently widely used perennial rye grass (Lolium perenne) are introduced in dairy farming, either as a monoculture or in a mixture. To study the effect of these grasses on yield and soil chemical and biological quality, the three species were sown in a field experiment in monoculture and in two mixtures.Within two growing seasons, the grass species tested under high soil fertility conditions did not show significant effects on most of the tested soil biological parameters. Only for the mixture of L. perenne and D. glomerata a higher soil NO3− and mineral N content were most probably related to a higher...

There is a need to develop sustainable and productive cropping systems for edible vegetable oilseeds in tropical Africa. Field trials were conducted during the late cropping season (July–Nov.) of 2001 and 2002 to determine the grain yields, and other yield attributes of sunflower and soyabeans and their productivity under monocropping and intercropping. Three sunflower (Helianthus annuus L.) varieties (a local adapted var. Funtua and two exotic varieties Isaanka and Record from Argentina) and five improved, high yielding soyabean (Glycine max (L.) Merrill) varieties: TGx 1448-2E (late), TGx 1440-1E (late), TGx 1019-2EB (medium), TGx 1740-2F (early) and TGx 1485-1D (early maturing) were used.

Productivity and quality, competition and facilitation of chicory in ryegrass/legume-based pastures under various nitrogen supply levels
Provedor de dados: 21
Autores: Høgh-Jensen, Henning; Nielsen, Bea; Thamsborg, Stig Milan.
Traditional perennial ryegrass-white clover mixtures have limitations in combined productivity and quality that herbs like chicory may alleviate. This study examined the consequences on productivity and quality of as well as competition and facilitation after introducing chicory into varies ryegrass-legume-based pastures in a field study over 3 consecutive growing seasons. A cultivar of chicory, suitable for grazing, in pure stand was found to out-yield a pure stand ryegrass in terms of dry matter and nitrogen (N) accumulation but was found to yield similar to mixture of chicory and ryegrass. The inclusion of chicory, increased N accumulation per area unit irrespective of associated leguminous species but had no effect (P&gt;0.05) on the combined dry...

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.

EFFECT OF LIVING MULCH MANAGEMENT ON NITROGEN DYNAMICS IN THE SOIL – PLANT SYSTEM OF CAULIFLOWER
Provedor de dados: 21
Autores: Tittarelli, Fabio; Kristensen, H.L.; Campanelli, G.; Bavec , F.; von Fragstein, P.; Testani, E.; Robacer , M.; Canali, S.
Living mulch management may have an effect on production of the crop and nutrient competition between the plant species in the field. In this paper, the amount of soil mineral nitrogen (N) available in the top soil during the cauliflower growing cycle and N uptake of the different components of the system were determined in two experimental sites in Italy and Slovenia where two different systems of living mulch management were compared (early sowed, late sowed) with a system with no living mulch. Moreover, nutritional competition of a hybrid and two open pollinated cultivars against weeds and living mulch was evaluated.

Autores: Brock, Christopher; Leithold, Prof.Dr. Günter; Schulz, Franz.
Year-to year changes of soil organic matter (SOM) have been surveyed in a long-term  experiment in order to allow for crop/cropping system impact assessment. Legumes  usually caused SOM build-up, which on the other hand only to a short extend  remained during the succeeding years. Considerable SOM decrease could be found  under potatoes. SOM dynamics under cereals varied strongly according to aspects of  the respective cropping system, especially precrop and fertilization. Green manure but  also farmyard manure obviously increased short-term decomposable fractions of  SOM, promoting mineralization of SOM in the following period. Long-term changes of  SOM in the experiment were somewhat less pronounced than year-to-year changes,  pointing on the high...

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,...

Biomass production, symbiotic nitrogen fixation and inorganic N use in dual and tri-component annual intercrops
Provedor de dados: 21
Autores: Andersen, Mette Klindt; Hauggaard-Nielsen, Henrik; Ambus, Per; Jensen, Erik Steen.
The interspecific complementary and competitive interactions between pea (Pisum sativum L.), barley (Hordeum vulgare L.) and oilseed rape (Brassica napus L.), grown as dual and tri-component intercrops were assessed in a field study in Denmark. Total biomass production and N use at two levels of N fertilisation (0.5 and 4.0 g N/m2), were measured at five harvests throughout a growing season. All intercrops displayed land equivalent ratio values close to or exceeding unity, indicating complementary use of growth resources. Whereas both rape and barley responded positively to increased N fertilisation, irrespective of whether they were grown as sole- or intercrops, pea was strongly suppressed when grown in intercrop. Of the three crops barley was the...

Life cycle assessment of organic and conventional arable  crop rotations -  focusing on greenhouse gas emissions.    Five arable crop rotations in long-term field trials were  investigated; four organic and one conventional - in three  years on three different locations in Denmark. The organic crop rotations represented alternative scenarios for outphasing conventional slurry in organic systems.    Crops from rotations with grass-clover for biogas in one out of four years had the lowest carbon footprint per kg crop DM. Including soil carbon changes in the life cycle assessment affected the results markedly.

One of the objectives of the TILMAN-ORG Project is to improve weed management under conservation agriculture (reduced tillage and/or cover crops) in organic arable systems. The shift from ploughing to conservation agriculture should not only maintain crop yield but possibly improve weed community diversity. This paper summarises the results on (1) weed abundance, (2) weed diversity and (3) crop yield obtained in the first year of the project (2012) in 13 trials scattered across Europe.

Abstract - Field experiments with spring wheat and faba bean were carried out at the Hessian State Estate Frankenhausen located near Kassel  in Central Germany in 2003 - 2005. As part of the EU Project “Intercrop”, spring wheat and faba bean were sown out as sole crops and intercropped with different seed rates, using two sowing techniques and with and without N supply. Intercropping was able to increase yield in the most treatments. All LER’s were higher than 1 and the N content in grain also increased in intercropped variants. The influence of the sowing technique was rather low in comparison to the seed rate.

Organic farming and the challenges of climate change
Provedor de dados: 21
Autores: Olesen, Jørgen E.
Climate change is without question one of the largest challenges that humankind has ever faced. This is not the least due to the enormous consequences that climate change will have for ecosystems and human society. Unfortunately, climate change also poses a very difficult problem for politicians to deal with. The core of the problem affecting modern democracies is that most people experience very little relationship between greenhouse gas emissions, climate change and their everyday life. There is both a temporal and spatial separation between emissions and impacts of climate change. The industrialized countries, which currently emit most of the greenhouse gases, are in general the least vulnerable to climate change effects. Additionally, many of the...

Facilitative root interactions in intercrops
Provedor de dados: 21
Autores: Hauggaard-Nielsen, Henrik; Jensen, Erik Steen.
Facilitation takes place when plants ameliorate the environment of their neighbours, and increase their growth and survival. Facilitation occurs in natural ecosystems as well as in agroecosystems. We discuss examples of facilitative root interactions in intercropped agroecosystems; including nitrogen transfer between legumes and non-leguminous plants, exploitation of the soil via mycorrhizal fungi and soil-plant processes which alter the mobilisation of plant growth resources such as through exudation of amino acids, extra-cellular enzymes, acidification, competition-induced modification of root architecture, exudation of growth stimulating substances, and biofumigation. Facilitative root interactions are most likely to be of importance in nutrient poor...

Rhizome Fragmentation by Vertical Disks Reduces Elymus repens Growth and Benefits Italian Ryegrass-White Clover Crops
Provedor de dados: 21
Autores: Ringselle, Björn; Bertholtz, Erik; Magnuski, Ewa; Brandsæter, Lars Olaf; Mangerud, Kjell; Göran, Bergkvist.
Tillage controls perennial weeds, such as Elymus repens, partly because it fragments their underground storage organs. However, tillage is difficult to combine with a growing crop, which limits its application. The aim of this study was to evaluate how soil vertical cutting with minimum soil disturbance and mowing affect the growth and competitive ability of E. repens in a grass–clover crop. A tractor-drawn prototype with vertical disks was used to fragment E. repens rhizomes with minimal soil and crop disturbance. In experiments performed in 2014 and 2015 at a field site close to Uppsala, Sweden, the rhizomes were fragmented before crop sowing (ERF), during crop growth (LRF), or both (ERF+LRF). Fragmentation was combined with repeated mowing (yes/no) and...

Optimisation of nitrogen mineralisation from winter cover crops and utilisation by subsequent crops
Provedor de dados: 21
Winter cover crops are integral to organic cropping systems; however, lack of knowledge concerning the fate of N following their incorporation presents a major barrier for efficient use of these crops in practice. Use of this N source is not only limiting to the production systems itself, but can also lead to loss of N via groundwater. This study will aim to quantitatively assess the fate of N from winter cover crops and investigate ways of optimising utilisation of this N source by subsequent organically-grown crops. The study will involve a mixture of field experimentation and computer modelling which will be carried out concurrently.  A series of field experiments will be conducted over 24 months on an organic site in order to quantitatively assess the...

Resource effective control of Elymus repens
Provedor de dados: 21
Autores: Ringselle, B.; Andersson, L.; Bergkvist, G.; Aronsson, H.
Preliminary results show that there is room for improvement within existing control methods of couch grass (Elymus repens (L.) Gould). It may be possible to reduce the number of stubble cultivations during autumn by timing the treatment, and to reduce the cultivation depth by using a goose foot cultivator (5 cm) instead of a disc cultivator (10 cm), without sacrificing couch grass control efficiency. The first year of the experiment, the use of a goose foot cultivator resulted in less nitrogen leaching than cultivation by disc. A reduced number of stubble cultivations potentially reduces nutrient loss, fuel consumption and the workload of the farmer.   Our experiments with cover crops to control couch grass in cereals has yet to prove significant effects...

Effect of differential N and S competition 1 in inter- and sole cropping of Brassica species and lettuce on glucosinolate concentration
Provedor de dados: 21
Autores: Stavridou, Eleftheria; Kristensen, Hanne L.; Krumbein, Angelika; Schreiner, Monika.
Field and greenhouse pot experiments were conducted to evaluate the potential to use intercropping as an alternative method to increase glucosinolates in Brassicas by manipulating nitrogen (N) and sulphur (S) balance by intercropping with lettuce (Lactuca sativa L. var. capitata). In both experiments, four combinations of N and S fertilization were used. In the field experiment no effect of intercropping on the total glucosinolates was found as the growing lettuce was strongly inhibited by the presence of broccoli (Brassica oleracea L. var italic). The reduction in neoglucobrassicin in broccoli from intercropping was probably attributed to the lower N concentrations in broccoli florets. In contrast to this, in the pot experiment both total and individual...

The cropping of leguminous cover crops usually leads to higher yields in subsequent cereals. The economic efficiency of leguminous cover crops was calculated in several field trials. Criterion was the yield (with adjusted costs) from the succeeding crops winter triticale and spring oats, respectively, after different leguminous cover crops undersown or as stubble seed in comparison to a control plot without cover crop. Thereby, the costs for seeds and the variable machine costs were taken into account.   The highest yield was reached for both types of grain following undersown white clover, the second highest following undersown black medic. In contrast, the yield was lower following red clover and grass-clover undersowings as well as different stubble...

N2-fixation and residual effect of four legume species and four companion grass species
Provedor de dados: 21
Autores: Rasmussen, J.; Søegaard, K.; Eriksen, J.
Inclusion of forage legumes in low-input forage mixtures improves herbage production and soil fertility through addition of nitrogen (N) from N2-fixation. The impact of different grass–legume mixtures on the N contribution of the forage mixture has rarely been investigated under comparable soil and climatic conditions. We conducted a field experiment on a sandy soil at two nitrogen levels with seven twospecies forage mixtures: alfalfa, bird’s-foot trefoil, red clover, or white clover in mixture with perennial ryegrass, and white clover in mixture with meadow fescue, timothy, or hybrid ryegrass. We found high N2-  fixation of more than 300 kg N ha−1 from both red clover and alfalfa even when the two mixtures received 300 kg total-N ha−1 in cattle slurry....

Grandes cultures bio sans bétail: résultats après 12 ans sur la ferme pilote de Mapraz
Provedor de dados: 21
Autores: Taramarcaz, Josy; Clerc, Maurice.
La ferme pilote de Mapraz a été mise sur pied pour répondre aux questions posées par la reconversion de fermes sans bétail à l'agriculture biologique. Après douze ans d'exploitation, dont les six dernières années ont comparé deux rotations (avec un ou deux ans de prairie temporaire PT), les rendements moyens sont inférieurs aux références de 8 % pour le blé ou comparables aux références bio pour la féverole et l'avoine. Les marges brutes sont inférieures de CHF 250/ha à CHF 670/ha aux références en agriculture biologique avec bétail.  La rotation avec deux ans de PT présente une meilleure marge brute (CHF 200/ha) et demande moins de travail (-2 heures/ha) que la rotation avec un an de prairie. Le chardon des champs a pu être diminué par l'introduction de...

Consequences of the introduction of cereal - grain legume intercrops in the supply chain. Analysis from the perspective of farmers and cooperatives
Provedor de dados: 21
Autores: Bedoussac, Laurent; Triboulet, P.; Magrini, M.-B.; Rambault, G.; Foissy, Damien; Corre-Hellou, Guénaëlle.
Intercropping (the simultaneous growth of 2 or more species in the same field) is one way to solve some difficulties that organic supply chain has to face. The aim of this article is to assess the consequences and the compatibility with intercrops at 2 levels: i) cropping systems of 18 farmers from north of France and ii) the logistics ofagricultural cooperatives which collect durum wheat in Midi-Pyrenees altogether with two cooperatives that already had experimented intercrops (Terrena and AgriBioUnion).The conclusions of our work is that intercrops seem a priori compatible with farmers’ cropping systems and with the presentlogistic organization of cooperatives but the main difficulty remains the feasibility and the cost in sorting out grains. Constraints...

I hvidkløvergræs øger afgræsning det ene år markant udbyttet i det næste sammenlignet med slæt. Rødkløver er et godt supplement i blandingen, idet den klarer sig godt  ved slæt, mens hvidkløveren tager over under afgræsning.  Samlet set giver rødkløver i blanding en mere robust mark og øget fleksibilitet med hensyn til markens brug.

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.

Can living mulches in intercropping systems reduce the potential nitrate leaching? Studies of organic cauliflower (Brassica oleracea L. var. botrytis) and leek (Allium porrum L.) production across European conditions
Provedor de dados: 21
Autores: Xie, Yue; Tittarelli, Fabio; von Fragstein, Peter; Bavec, Martina; Canali, Stefano; Kristensen, Hanne Lakkenborg.
The effect of introduction strategy for living mulches (LMs) to reduce the potential nitrate leaching was investigated when grown with vegetables with high nitrogen (N) demand and low use efficiency in four European countries: Italy, Slovenia, Germany and Denmark over 2 yr. The plant N uptake and soil nitrate N content at harvest, in the autumn, and in the following spring were measured below open-pollinated and hybrid cultivars of cauliflower and leek crops. The cultivars performed differently over the 2 yr. In Italy and Slovenia, when LM of burr medic or white clover was broad sown (addition design ADD) at the same time as crop transplanting, the N uptake of crops was hampered without increasing the total aboveground N accumulation. Delaying LM sowing by...

Lille effekt af fangafgrøder
Provedor de dados: 21
Autores: Jensen, Lars Stoumann.
Økologisk produktion af salgsafgrøder uden tilførsel af fosfor (P) eller kalium (K) vil med tiden kunne begrænses af næringsstofmangel, ikke mindst i afgrødernes etableringsfase, hvor de har et lille rodsystem. Hvor lang tid der går før problemet opstår, afhænger blandt andet af jordens næringsstof status ved omlægning til økologi. Vi ved at efterafgøder kan være et godt redskab til at flytte rundt på tilgængeligt kvælstof (N) i et økologisk sædskifte, men gælder det også P og K når jordens status bliver lav? Dette har vi undersøgt i FØJO-II projektet VegCatch med titlen "Økologiske grønsager og efterafgrøder".

Management affects nitrate leaching from organic farms
Provedor de dados: 21
Autores: Askegaard, Margrethe; Eriksen, J.
Management decisions significantly affect nitrate-N leaching (N-leaching) from comparable organic fields. The main concern is field management during autumn and themanagement of grass leys. After ploughing-in fertility building crops, like grass-clover leys, effective catch crops are important during autumn and winter for at least two years on sandy soils. On farms with grazing animals the occurrence of “hot spots” should be avoided. These hot spots develop with uneven concentrations of animal manure combined with limited N-uptake in the ley. Management measures to minimize N-leachingmay conflicts with the farmers aim to produce high quality feed and/or to combat yield limiting perennial weeds. It may also conflict with the organic regulations for the...

In organic farming the cultivation of leguminous crops is one of the most important sources of nitrogen (N). However, in the case of winter field peas, the amount of N fixed, N supply to the subsequent crop and N balance there are hardly any published data. Therefore, the pre-crop effect of six genotypes of winter pea (five regular leaf type, one semi-leafless cultivar) and one semi-leafless spring pea cultivar in single and mixed cropping (with rye spring barley respectively) was examined in three suc-cesive growing seasons (2003/04-2005/06). Immediately after harvest, a catch crop was sown and sampled during the first half of October to determine biomass dry matter and N uptake.   In single cropping, N uptake by the catch crop was usually significantly...

Nitrogen fertilizer replacement value of digestates  from three green manures
Provedor de dados: 21
Autores: De Notaris, C.; Sørensen, P.; Møller, H.B.; Wahid, R.; Eriksen, J.
Green manure mixtures including legumes and forbs can help to increase N availability in organic arable systems. Anaerobic digestion of green manures may provide ammonium rich digestate, which can be redistributed as fertilizer. The aim of this study was to investigate the effect of plant species composition, cutting strategy and anaerobic digestion on the N fertilizer replacement value (NFRV) of different green manures. Digestates obtained from silages of pure stand lucerne (four cuts/year) and a mixture including lucerne, grass and forbs (two or four cuts/year) were used to fertilize winter wheat (surface banding) and spring barley (injection). In general, NFRV was 46–173% higher in spring barley than winter wheat, due to the different application method...

Autores: Baresel, Jörg Peter; Köckeis, M.; Weiner, J.
The success of the establishment of living mulch systems in cereals depends, among other factors, on the spacial seed arrangement of the main crop and the associated  crop as well as on the nitrogen availability. A series of experiments with three different types of seed arrangement has been performed in southern Germany and central Italy  in order to assess the role of this factor using model systems with wheat and subterranean clover. The effect of nitrogen availability was tested in a separate experiment with 12 different levels of N fertilization. The best seed arrangement was narrow alternate rows, where competition between crops is reduced in the early growth stages. At higher N fertilization rates, subterranean clover was suppressed; however, at...

Autores: Hauggaard-Nielsen, Henrik.
For at sikre integriteten af økologisk jordbrug er det vigtigt at reducere afhængigheden af fossil energi. Produktion af bioenergi ud fra lokal biomasse med en samtidig vedligeholdelse af jordens frugtbarhed betragtes dog af nogle økologer som uforenelige målsætninger. I forskningsprojekter BioConcens testes et stribedyrkningskoncept, hvor en enårig stribe benyttes til produktion af energi/fødevarer/foder, og en flerårig til energi/foder samt opbygning af jordens frugtbarhed.   Stribedyrkning betragtes som en modereret og mere arbejdseffektiv form for blandingsafgrøde. Hver afgrøde etableres i striber med en bredde, der sikrer interaktion mellem afgrøderne og som samtidig tilpasses lokalt maskinel. Derved fungerer de enkelte striber som individuelle...

The several advantages of conservation tillage systems are interesting for organic  farmers too. The positive effects concerning the reduction of soil erosion are well  known and documented. The more residues are left on the soil surface the higher  reduction of soil erosion is achieved. Nevertheless the plough is still the main tillage  equipment in organic agriculture systems. A first step towards conservation tillage  might be the tillage before intercrops. In a three years project the relationship of  emergence rate from straw quantity, working depth and residue cover is investigated.  Thick mulch layers have negative effects on the emergence rate of the followed crop.  Modern machinery for conservation tillage improve the incorporation of crop...

Winterbeweidung als Alternative zur Mulch- bzw. Schnittnutzung von Kleegrasschlägen [Winter grazing, an alternative to mulching or mowing of grass clover swards]
Provedor de dados: 21
Autores: Westphal, D.; Loges, R.; Taube, F.
Literature shows that management factors like the type of defoliation and seed mixture have a strong influence on yield, forage quality and N2-fixation of grass clover mixtures. In comparison to harvesting, grazing is cheaper and for economical reasons a maximum grazing period is aimed. Grazing over winter time can cause irreparable damages to the pasture. This problem is of minor relevance for grass clover grown on arable land in its last production year, which it’s ploughed anyway in the following spring. This study compares different grass clover mixtures concerning yield, forage quality and suitability for winter grazing.  Grass clover swards varying with respect to the following experimental factors: I. com-panion grass species (perennial ryegrass...

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...

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....

Provedor de dados: 21
Autores: Sánchez de Cima, Diego; Luik, Anne; Reintam, Endla.
For testing how cover crops and different fertilization managements affect the soil physical properties in a plough based tillage system, a five-year crop rotation experiment (field pea, white potato, common barley undersown with red clover, red clover, and winter wheat) was set. The rotation was managed under four different farming systems: two conventional: with and without mineral fertilizers and two organic, both with winter cover crops (later ploughed and used as green manure) and one where cattle manure was added yearly. The measurements conducted were penetration resistance, soil water content, porosity, water permeability, and organic carbon. Yearly variations were linked to the number of tillage operations, and a cumulative effect of soil organic...

Soil P and K availability defines below-ground biomass allocation of grass-legume leys
Provedor de dados: 21
Autores: Cong, W.-F.; Christensen, B.T.; Eriksen, J.
Exploring the response of above- and below-ground biomass allocation to soil nutrient availability is crucial to reliably estimating root carbon (C) input and predicting long-term soil C dynamics. Despite this, belowground C input is often estimated by using yield-based allometric equations without considering the impacts of environmental factors or management practices such as fertiliser levels, which could lead to erroneous and uncertain estimates.

Genetisk diversifiering som ett redskap att minska insektsskador i ekologisk grönsaksodling
Provedor de dados: 21
Syftet med projektet är att öka lönsamheten i ekologisk grönsaksodling, framför allt inom kålodling, genom att utveckla ett odlingssystem för samodling av kålsorter eller variteter. Den teoretiska idén bakom odlingssystemet är att minska förluster på grund av skadeinsekter genom att manipulera insekternas äggläggningsbeteende och genom att minska överlevnaden hos larver. Det huvudsakliga fokuset i projekt kommer att vara att minska effekten av kålflugor men i ett längre perspektiv är syftet också att utveckla en kvantitativ metod som kan användas vid utveckling av motsvarande odlingssystem för andra grönsakssorter.

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...

Evaluation of Crop Rotation on Organic Farms in Northern Serbia
Provedor de dados: 21
Autores: Seremesic, Mr Srdjan; Milosev, Dr Dragisa; Manojlovic, Dr Maja.
The objective of this paper was to analyze six organic farms in northern Serbia in order to evaluate crop rotation composition and identify its role in cropping technology of the organic production. The major agronomic indicators of organic crop rotation were analyzed: number of crops and their ratio, number of different crop schemes and fields in rotation, land coverage with crops, crops structure, etc. Information was acquired by visiting and surveying farmers during the 2005/06 as well as reading their documentation required for certification. The obtained results showed that the farmers carried out production on a 3-4-year rotation basis. The cropping plan was strongly driven by market demands. Compromises with design and structure of the rotation were...

Udbytter i langvarige økologiske planteavlssædskifter
Provedor de dados: 21
Autores: Sørensen, Peter; Nielsen, Erling; Olesen, Jørgen E.
Udbytter målt i sædskifteforsøg i Foulum 2010 og 2011.    Resultater fra det langvarige sædskifteforsøg på Foulum viser, at sædskifter med grøn-gødningsafgrøde giver højere udbytter end i tilsvarende sædskifter uden grøngødning. Dette gælder i de første 2 år efter nedpløjning af grøngødning, mens der kun var udbytte effekt af grøngødningen i ugødet vårbyg det 3. år efter ompløjning af grøngødningen. I sædskiftet uden grøngødning var der generelt gode udbytteeffekter af kvælstoffikse-rende efterafgrøder. Konsekvent anvendelse af kvælstoffikserende efterafgrøder har haft næsten samme positive effekt på udbytter som en helårs grøngødningsafgrøde i sædskif-tet.

Competition and complementarity in annual intercrops - the role of plant available nutrients
Provedor de dados: 21
Autores: Andersen, Mette Klindt.
In the developed regions of the world crops are today primarily grown as sole crops and monocultures. However, increasing awareness of the link between agricultural practise, environmental issues and long-term stability of existing food production systems has put focus on the role that greater crop diversity in time (crop rotation) and space (field size and mixed cropping systems) may play in reducing the extent of these problems. Intercropping represents one way of increasing crop diversity. As a result of differences in the way component crops respond to and affect the environment in which they are grown intercrops may use available growth resources (light, water and nutrients) more efficiently, reduce the prevalence of disease and pests and reduce weed...

Kyllinger gør ikke så megen forskel
Provedor de dados: 21
Autores: Pedersen, Hanne Lindhard.
Mindre røde æbler var en af de synlige konsekvenser af at have kyllinger i æbleplantagen.    Kombinationsproduktion af slagtekyllinger og frugtdyrkning er kendt men ikke særligt udbredt. De seneste to somre har vi lavet forsøg med slagtekyllinger i en æbleplantage på Fejø Forsøgsplantage som led i et QEMP-projekt under ICROFS.  De foreløbige resultater viser, at kyllingernes tilstedeværelse kun har haft begrænset effekt på æbleproduktionen, men det endelige billede tegner sig først, når projektet slutter næste år, og man kan se eventuelle eftervirkninger af kyllingerne.

Intercropping of oilseeds and faba beans
Provedor de dados: 21
Autores: Kießling, Daniela; Köpke, Prof. Dr. Ulrich.
Intercrops are considered as less susceptible to pests and diseases and may inhibit weeds more efficiently resulting in enhanced yields and profitability. N2 fixation of legumes is an important nitrogen (N) input factor of Organic Farming systems and results in partly unused plant available soil N (PAN) in sole cropped faba beans. Simultaneously cultivated oilseeds may function as sinks for PAN and enhance biodiversity with all positive aspects. In this respect we investigated several oilseeds intercropped with faba beans at different row distances. Depending on row distance we analysed e.g. the use of soil nutrients and land equivalent ratio (LER). Intercropped oilseeds depleted PAN between FB rows significantly in early development. In 2007 yield...

Autores: Donkó, Ádám; Miglécz, Tamás; Valkó, Orsolya; Deák, B.; Kelemen, A.; Török, Péter; Tóthmérész, Béla; Zsigrai, György; Drexler, Dora.
Intensive mechanical soil cultivation and herbicide treatment was often the preferred technology in vineyards in the second half of the 20th century. In the last decades we  increasingly experienced the disadvantages of these technologies: soil degradation, erosion and deflation damages. The use of well-adapted cover-crop mixtures could be an alternative. In 2012 we started to study three different species-rich cover crop mixtures (Biocont-Ecovin, Legume mixture, Grass-herb mixture) in Hungarian  vineyards. For 2013 we detected lower weed coverage in the inter-rows sown with the Grass-herb and Legume mixtures, while in control and Biocont-Ecovin inter-rows we  detected increasing weed coverage. In the third year (2014) we found in case of every plot that...
