Vineyard water status assessment using on-the-go thermal imaging and machine learning
Provedor de dados: 21
Autores: Gutiérrez, S.; Diago, M.P; Fernandez-Novales, J.; Tardaguila, J.
The high impact of irrigation in crop quality and yield in grapevine makes the development of plant water status monitoring systems an essential issue in the context of sustainable viticulture. This study presents an on-the-go approach for the estimation of vineyard water status using thermal imaging and machine learning. The experiments were conducted during seven different weeks from July to September in season 2016. A thermal camera was embedded on an all-terrain vehicle moving at 5 km/h to take on-the-go thermal images of the vineyard canopy at 1.2 m of distance and 1.0 m from the ground. The two sides of the canopy were measured for the development of side-specific and global models. Stem water potential was acquired and used as reference method....

Framework in Agriculture on the Farm Level
Provedor de dados: 21
Autores: Haas, G.; Wetterich, F.; Geier, U.
Life Cycle Assessment (LCA) is a method that can be used to assess the environmental impact of agriculture, but impact categories and the functional unit of classical LCA’s must be adapted to the specific agricultural production process. Serving as an example, the framework of a LCA of 18 grassland dairy farms covering three farming intensity levels and carried out in the Allgäu region in southern Germany is presented. By focussing on the chosen impact categories and the respective, suitable functional units, the specific needs and backgrounds of conducting an agricultural LCA are discussed in general.    aus: Haas, G. und Wetterich, F. und Geier, U.

Earthworm sampling
Provedor de dados: 21
Autores: Peigne, Joséphine; Huber, Kathrin; Pfiffner, Lukas.
Earthworms are key organisms and indicators of soil quality, which also links to the productivity of an ecosystem. The higher the earthworm density and diversity, the better the earthworm’s living conditions and the more fertile is the soil. They are relatively easy to detect and determine into three ecological groups.    The number and distribution of the three ecological categories and the numerous earthworm species depends on soil management, soil type, the Vegetation and climate conditions.    In this technical note, various methods how to sample,   measure and interpret earthworms are shown.

Monitoring nutrient turnover during composting has to be based on a constant reference parameter. Is total ash content really a good choice?
Provedor de dados: 21
Autores: Raupp, Dr Joachim.
The total ash content is usually considered to be fairly constant during the composting period, apart from addition of minerals by precipitation and losses by seepage. However, our field trials with farmyard manure have shown that the ash fraction insoluble in hydrochloric acid increased much more than the soluble fraction in the same time. If changes are merely caused by composting intensity (e.g. organic matter degradation), both fractions should be accumulated in the same degree. It is hypothesized that the higher rise of the HCl-insoluble fraction indicates a higher amount of soil material in the heaps at the end compared to the beginning of composting, as the insoluble fraction originates mainly in soil-borne silicates while the soluble fraction is...

Microbial Community Structure and Litter Decomposition in Stratified Soils of a Long Term Reduced Tillage Experiment
Provedor de dados: 21
Autores: Suhadolc, M.; Baškovč, M.; Kaurin, A.; Kastelec, D.; Mihelič, R.
The aim of the present study was to examine decomposition of plant material (maize straw, green and rooibos tea) in stratified soils of the long-term tillage experiment, established in 1999 and shifted from conventional to organic farming system in 2015.    The plowing in conventional tillage (CT) has been done by moldboard plow 20 cm deep, while in minimum tillage (MT), soil disturbance has been up to 10 cm deep by a Special disc harrow. More than 15 years of long term Minimum tillage, with reduced soil disturbances and improved residue management, resulted in stratification of soil organic carbon and nutrients with highest concentrations in the very topsoil.

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...

Studying conversion as a human activity system
Provedor de dados: 21
Autores: Padel, Susan.
This report was presented at the UK Organic Research 2002 Conference. Farmers convert to organic farming for a variety of reasons including environmental concerns, problems with conventional systems, and personal and financial reasons. They also vary in their management styles. These personal characteristics are rarely considered as explaining variables in comparative studies of farming systems, because of the contrasting methods used to evaluate personal objectives and attitudes as opposed to farm activities. Farming should be seen as a human activity system, in which people actively manage some natural resources, for the purpose of producing output, influenced by their subjective values and attitudes. The Farming Systems Research (FSR) approach aims to...

Comparisons of organic and conventional maize and tomato cropping systems from a long-term experiment in California
Provedor de dados: 21
Autores: Kaffka, Stephen; Bryant, Dennis; Denison, Ford.
Yield differences and trends, organic matter accumulation, and the loss of nutrients to deeper soil horizons are discussed using data from organic and conventional maize/tomato cropping systems from the Long Term Research on Agricultural Systems Project (LTRAS) at the University of California, Davis.  Compared to the conventional system, higher and increasing yields of tomatoes were observed in organic systems, but lower yields of maize.  Fruit quality, measured as soluble solids, was not significantly different.  Soil organic matter increased in the organic system, but remained stable in the conventional one.  More irrigation water was used in the organic system than in the conventional one due to higher rates of infiltration, but less winter runoff...

What drives farmers’ sustainability performance? Application of the CSP Modell for the analysis of farmers’ Conditions, adaptation Strategies and sustainability Performances – a case study analysis of German and Swedish producer groups in times of change
Provedor de dados: 21
Autores: Münchhausen, von, Susanne; Knickel, Karlheinz; Milestad, Rebecka; Lasner, Tobias.
This paper aims to explore farmers' conditions, strategies and performances in a context of multi-dimensional policy requirements, market imperfections and globalisation. The basic assumption sees conditions as drivers for farmers’ strategies that then result in performances of the sector. The methodological approach is based on the Conditions-Strategies-Performances (CSP) model which is used for the analysis of three case studies. The model helps to identify changes in framework conditions over time, resources among relevant groups of primary producers, adaptation strategies and finally, to explore the related social, economic and environmental effects. The analysis is based on three case studies, three farmers’ groups in Germany and Sweden. Results show...

How economic is organic? Results of a long-term trial at Burgrain/Lucerne, Switzerland
Provedor de dados: 21
Autores: Fried, Padruot M.; Zihlmann, Urs; Strasser, Fredi; Tschachtli, Ruedi; Ammann, Helmut; Dubois, David.
Long-term trials are necessary not only to judge agronomic and ecological indicators when studying organic farming, but also to analyze and describe economic parameters. From 1997-2002, an organic arable farming system (Bio) was compared with two Integrated farming systems (IP intensive and IP extensive) on 6 plots in a 6-year crop rotation at Burgrain near Lucerne, Switzerland. The 6 plots were subdivided into 3 subplots of 0.65 ha each. In the organic system, the input of fertilizer and pesticides was substantially reduced, which resulted in a yield reduction of 19% over all 4 arable crops and of 14% if the temporary lays are included. Nevertheless, the organic system showed an excellent net profit, mainly due to the higher prices paid to the farmers for...

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

Ökologische Bewirtschaftung erfordert die Steuerung von innerbetrieblichen Nährstoffflüssen
Provedor de dados: 21
Autores: Sundrum, Albert.
Self-organised ecosystems are characterised by a high efficiency in the use of limited nutrient resources whereas the productivity is generally low. To utilise the potentials of agro-ecosystems with respect to a high nutrient efficiency, there is a need to steer the nutrient flow and provide good starting and adaptation conditions for living organisms.   While organic standards provide no operational guidelines on how to improve nutrient management, a concept was developed to improve N-efficiency on the farm level. N-import into the farm and N-flow through subordinate sub-systems (‘livestock’, ‘dung storage/ distribution’, ‘arable land/pasture’, and ‘feed storage/distribution’) were assessed on 9 organic and 7 conventional dairy farms, based on farm...

The Glenlea long-term rotation study, located near Winnipeg, is Canada’s oldest conventional vs organic crop comparison study.  Since 1992, three farming systems (grain only; grain with green manure crops; combined grain-forage rotation) were evaluated under two management systems (organic and conventional).  Organic system ranked higher than conventional systems in energy efficiency and biodiversity while conventional system ranked higher in yield, weed management and soil nutrient status.  However, significant farming system by management interactions were observed for many variables.  The basis for these interactions was enhanced performance of organic production in the combined grain-forage system compared with the grain only system.  Organic crop...

LONG-TERM ORGANIC CROP ROTATION EXPERIMENTS FOR CEREAL PRODUCTION – PERENNIAL WEED CONTROL AND NITROGEN LEACHING
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Askegaard, Margrethe; Olesen, Jørgen E.
In long-term organic crop rotation experiments for cereal production, stubble cultivation to control perennial weeds increased nitrogen leaching compared to catch crops grown after harvest. Stubble cultivation contributed to the control of Elymus repens on a sandy soil, but not to the control of Cirsium arvense on a loamy soil. Manure application had a tendency to decrease E. repens density in one rotation at the sandy soil. Grass-clover green manure decreased C. arvense in the succeeding crops. Despite high infestations of perennial weeds, yields were at the same level with as without stubble cultivation. The results point to an important dilemma in organic farming: should the farmer control perennial weeds in the stubble at the expense of losing nitrogen...

Autores: Gambelli, Danilo; Vairo, Daniela; Zanoli, Raffaele.
The development of scenario analysis (SA) to assist decision makers and stakeholders has been growing over the last few years through mainly exploiting qualitative information provided by experts. In this study, we present SA based on the use of qualitative data for strategy planning. We discuss the potential of SA as a decision-support tool, and provide a structured approach for the interpretation of SA data, and an empirical validation of expert evaluations that can help to measure the consistency of the analysis. An application to a specific case study is provided, with reference to the European organic farming business.

Parameters for apple quality - 2 - and the development of the ‘inner quality concept’ 2001-2003
Provedor de dados: 21
Autores: Bloksma, Joke; Huber, Machteld; Northolt, Martin; Zanen, Marleen; Jansonius, Pieterjans.
We found clear correlations between management measures, tree characteristics and fruit characteristics. This means that growers can regulate apple quality during the growing season. On the basis of the two apple experiments, we can distinguish respective sets of growth and differentiation parameters and evaluate them in the light of conventional fruit cultivation science. Our results have little new value for fruit growing in practice, however. The value of our research lies in the approach developed to draw up a quality concept and the way in which we can apply this concept to crops about which little knowledge exists regarding the relationship between management measures, crop characteristics and product quality characteristics. Our research also offers...

The impact of long-term organic farming on soil-derived greenhouse gas emissions
Provedor de dados: 21
Autores: Skinner, Colin; Gattinger, Andreas; Krauss, Maike; Krause, Hans-Martin; Mayer, Jochen; van der Heijden, Marcel G. A.; Mäder, Paul.
Agricultural practices contribute considerably to emissions of greenhouse gases. so far, knowledge on the impact of organic compared to non-organic farming on soil-derived nitrous oxide (N2o) and methane (CH4) emissions is limited. We investigated N2o and CH4 fluxes with manual chambers during 571 days in a grass-clover– silage maize – green manure cropping sequence in the long-term field trial “DOK” in Switzerland. We compared two organic farming systems – biodynamic (BIODYN) and bioorganic (BIOORG) – with two non-organic systems – solely mineral fertilisation (CONMIN) and mixed farming including farmyard manure (CONFYM) – all reflecting Swiss farming practices–together with an unfertilised control (NOFERT). We observed a 40.2% reduction of N2o emissions...

Guidelines for physical weed control research: flame weeding, weed harrowing and intra-row cultivation
Provedor de dados: 21
Autores: Vanhala, P.; Kurstjens, D.; Ascard, J.; Bertram, A.; Cloutier, D.C.; Mead, A.; Raffaelli, M.; Rasmussen, Jesper.
A prerequisite for good research is the use of appropriate methodology. In order to aggregate sound research methodology, this paper presents some tentative guidelines for physical weed control research in general, and flame weeding, weed harrowing and intra-row cultivation in particular. Issues include the adjustment and use of mechanical weeders and other equipment, the recording of impact factors that affect weeding performance, methods to assess effectiveness, the layout of treatment plots, and the conceptual models underlying the experimental designs (e.g. factorial comparison, dose response).  First of all, the research aims need to be clearly defined, an appropriate experimental design produced and statistical methods chosen accordingly. Suggestions...

Drohnenbilder zur Untersuchung von Pflanzenwachstum und Nährstoffdynamik
Provedor de dados: 21
Autores: Wittwer, Raphaël; Tombez, Grégoire; van der Heijden, Marcel.
Ein besseres Verständnis der Dynamik hinter der Freisetzung von pflanzenverfügbaren Nährstoffen aus Boden oder organischen Dünger und eine Verbesserung der Nährstoffverwertung von Ackerfrüchten sind zwei wichtige Herausforderungen, um die Produktivität im ökologischem Ackerbau zu erhöhen. Doch diese Prozesse sind stark sowohl von biotischen (z.B. Bodenmikroben) als auch abiotischen (z.B. Temperatur, Niederschlag, Bodenfeuchtigkeit, Bodenstruktur) Faktoren beeinflusst und erschweren effiziente Untersuchungen. Fernbilderkundung-Technologien (remote sensing) haben sich in den letzten Jahren stark weiterentwickelt und bieten heute neue Ansätze und Methoden, um der Ernährungsstatus von Pflanzen sowie die Dynamik des Pflanzenwachstums nicht destruktiv zu...

Soil Fragmentation and Friability. Effects of Soil Water and Soil Management
Provedor de dados: 21
Autores: Munkholm, Lars J.
Soil fragmentation is a primary aim in most tillage operations in order to create a soil environment favourable for crop establishment and growth. Soils vary around the world from those exhibiting a self-mulching nature to those of a hardsetting nature. These extremes have been reported for Australian and other tropical and subtropical soils. In humid temperate climates, soil tillage is generally needed in order to produce a favourable environment for crop establishment and growth. The ease of preparing a favourable arable layer depends on complex interactions between climate, soil and the tillage implement. Especially soil water affects soil strength and fragmentation properties and thereby the ease of preparing a suitable arable layer. Soil management...

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.

Quantification of root fungi using signature fatty acids
Provedor de dados: 21
Autores: Ravnskov, Sabine; Jensen, Birgit; Nielsen, Steen Lykke; Larsen, John.
Both deleterious (pathogenic) and beneficial (mycorrhizal) fungi inhabit plant roots with strong impact on plant growth and health. Various methods have been used to quantify these fungi, such as indirect measurements of plant parameters, disease index, staining techniques and serological/genetic/biochemical markers. The objective of this work is to evaluate the possibility of using signature fatty acids to quantify root-inhabiting fungi in planta and in soil. Different fatty acid-based methods can be used to quantify fungi. Phospholid fatty acids (PLFA) can be used for biomass estimation and neutral lipid fatty acids (NLFA) for estimation of fungal energy reserves and the NLFA/PLFA ratio can give information on the physiological status of the fungus. It...

Crosstalk between Innate Immunity and Circadian Rhythm: Do fish immune defences have a sense of time?
Provedor de dados: 21
Autores: Lazado, Carlo Cabacang; Lund, Ivar; Skov, Peter V.; Jokumsen, Alfred; Gesto, Manuel; Nguyen, Huy Quang; Pedersen, Per Bovbjerg.
Circadian rhythms established by the endogenous clocks enable organisms to anticipate periodic and cyclic changes in their environment. This internal time-keeping system is highly conserved amongst animals and provides them with adaptive advantages as biological processes can be scheduled to occur at the most crucial times of the day. Circadian rhythm is emerging as an important regulator of immune functions. However, there is a paucity of information on the influence of this biological phenomenon in the immune mechanisms of teleost fish. A series of studies was conducted to investigate the circadian rhythms of systemic and mucosal innate immunity using model (i.e., zebrafish, Danio rerio) and non-model (i.e., permit, Trachinotus falcatus; rainbow trout,...

Interpreting soil organic matter characteristics in organic farming systems
Provedor de dados: 21
Autores: Wander, Michelle M.; Marriott, Emily E.; Wang, Yun.
Soil organic matter (SOM) fraction characteristics need to be developed as indicies that can be related to specific soil functions.  The general effects of organic management on prominsing indicies of SOM status (POM and a rapid measure of base hydrolyzable N) were determined by comparing the characteristics of organic and conventionally managed soils obtained from nine long-term trials in North America.  In addition, a more detailed study was conducted of POM and of hydrolyzable N fractions (including amino-acids, amino sugars) at a site where use of organic practices failed to increase SOM.  In the multi-site comparrison, legume- and manure-based organic systems performed equally well in their ability to increase the quantity of SOM as well as enrich the...

Life Cycle Assessment of Conventional and Organic Farming in the DOC trial
Provedor de dados: 21
Autores: Nemecek, Thomas; Dubois, David; Gunst, Lucie; Gaillard, Gérard.
The environmental impacts of the conventional and organic farming systems practised in the DOC trial (organic-dynamic, organic and conventional farming) have been assessed by the SALCA life cycle assessment method. Both organic farming systems were more favourable for the environment in all investigated impacts per area unit. When analysed per product unit, clear advantages of organic farming were found for ecotoxicity and the use of mineral resources, while energy use and eutrophication were similar to conventional farming. Reducing fertilisation by 50% led to lower or equal environmental impacts for all systems, depending on the impact category and the functional unit. The analysis of single crops revealed large differences that are partly...

Provedor de dados: 21
Autores: Hagel, Ingo.
[Einleitung:]  Die Biologisch-Dynamische Wirtschaftsweise ist die älteste unter den verschiedenen Methoden des Ökologischen Landbaus. Ihr geistiges Fundament ist eine Reihe von Vorträgen, die Rudolf Steiner (1861-1925) im Jahr 1924 in Koberwitz bei Breslau für Landwirte hielt (STEINER 1924a). Daher können ihre Voraussetzungen und Intentionen und auch ihr Forschungsansatz nicht losgelöst von dem spirituellen Weltbild der Anthroposophie, deren Begründer Rudolf Steiner ist, betrachtet werden. Auf einige Motive und Aspekte dieser Herangehensweise an wissenschaftliche Fragestellungen soll hier kurz eingegangen werden.

Origin and composition of Dissolved Organic C and N from grass-clover mixtures
Provedor de dados: 21
Autores: Rasmussen, Jim; Høgh-Jensen, Henning.
The C and N dynamics in perennial grass-clover mixtures are not fully understood although such mixtures dominate temperate grassland. The co-existence of clover and grass involves both competition for and transfer of nutrients between the species. The nutrients may originate from leaky root systems, from a rapid turnover of the fine root systems, or from degradation of more stabile organic material.     The aim of the study is  - to determine the origin of DOC and DON in grass-clover mixtures  - to determine the composition of DOC and DON from the species  - to investigate the transfer of C and N between grass and clover    Method:  In a third year grass-clover ley at the KVL research fields, mezotrons were installed to depths of 20, 40 and 60 cm in...

Restricting the nonlinearity parameter in soil greenhouse gas flux calculation for more reliable flux estimates
Provedor de dados: 21
Autores: Hüppi, Roman; Felber, Raphael; Krauss, Maike; Six, Johan; Leifeld, Jens; Fuß, Roland.
The static chamber approach is often used for greenhouse gas (GHG) flux measurements, whereby the flux is deduced from the increase of species concentration after closing the chamber. Since this increase changes diffusion gradients between chamber air and soil air, a nonlinear increase is expected. Lateral gas flow and leakages also contribute to non linearity.  Several models have been suggested to account for this non linearity, the most recent being the Hutchinson±Mosier regression model (HMR). However, the practical application of these models is challenging because the researcher needs to decide for each flux whether a nonlinear fit is appropriate or exaggerates flux estimates due to measurement artifacts. In the latter case, a flux estimate from the...
