Conservation tillage in organic farming Organic Eprints
Krauss, Maike; Mäder, Paul; Peigne, Joséphine; Cooper, Julia.
Conservation tillage in organic farming combines the principles of organic farming with the benefits of soil erosion control achieved by the conversion from ploughing to either reduced tillage or no-tillage/direct-seeding. This chapter reviews more than two decades of on-station and on-farm research. The chapter outlines the main benefits of conservation tillage before considering its main challenges. The chapter also contains a number of specific case studies from the field. Finally, the chapter looks ahead to future research trends in this area and offers detailed guidance on where to find further information about this subject.

Peigne, Joséphine; Casagrande, Marion; David, Christophe; Sans, Francesc Xavier; Blanco-Moreno, José Manuel; Cooper, Julia; Gascoyne, Kate; Antichi, Daniele; Bàrberi, Paolo; Bigongiali, Federica; Surböck, Andreas; Kranzler, Andreas; Beeckman, Annelies; Willekens, Koen; Luik, Anne; Matt, Darja; Grosse, Meike; Heß, Jürgen; Clerc, Maurice; Dierauer, Hansueli; Mäder, Paul.
The interest of organic farmers for adopting conservation agriculture practices is currently growing. But, there are few technical and scientific references available for organic farmers when they start applying conservation agriculture practices. The main objectives of this study are (1) to explore the diversity of crop management practices using conservation agriculture methods among European farmers, and (2) to identify main farmers’ strategies. We carried out a survey of 159 farmers located in 10 European countries with a questionnaire with closed-ended questions. Data were analysis with a multi factor analysis followed by clustering to identify groups of farmers that share the same type of spring and winter crop managements. Organic farmers in Europe,...

Effects of agricultural production systems and their components on protein profiles of potato tubers Organic Eprints
Lehesranta, Satu J.; Koistinen, Kaisa M.; Massat, Nathalie; Davies, Howard V.; Shepherd, Louise V. T.; McNicol, James W.; Cakmak, Ismail; Cooper, Julia; Lück, Lorna; Kärenlampi, Sirpa O.; Leifert, Carlo.
A range of studies have compared the level of nutritionally relevant compounds in crops from organic and nonorganic farming systems, but there is very limited information on the effect of farming systems and their key components on the protein composition of plants. We addressed this gap by quantifying the effects of different farming systems and key components of such systems on the protein profiles of potato tubers. Tuber samples were produced in the Nafferton factorial systems study, a group of long-term, replicated factorial field experiments designed to identify and quantify the effect of fertility management methods, crop protection practices and rotational designs used in organic, low input and conventional production systems. Protein profiles were...

Facing up to the phosphorus challenge Organic Eprints
Løes, Anne-Kristin; Cooper, Julia; Gascoyne, Kate.
The loss of phosphorus in exported products is a concern for all organic producers. The team of CORE Organic Project "Improve-P" assess attitudes to alternative phosphorus fertilisers among organic stakeholders. This paper reports on results collected via a questionnaire at the National Soil Symposium in Solihull, UK November 2014. 58 respondents showed a large interest in recycled P fertilisers, e.g. derived from human urine. One respondent who summed up the workshop in this way: Ultimately for sustainability we have to replace P, lost off farm but balance between purity and recycling is a difficult one. We need to focus on making best use of P reserves in soil, for example deep-rooting green manures, efficient composting, P scavenging plants, that is,...

How organic farmers practice conservation agriculture in Europe Organic Eprints
Peigne, Joséphine; Casagrande, Marion; Payet, Vincent; David, Christophe; Sans, F. Xavier; Blanco-Moreno, José M.; Cooper, Julia; Gascoyne, Kate; Antichi, Daniele; Bàrberi, Paolo; Bigongiali, Federica; Surböck, Andreas; Kranzler, Andreas; Beechman, Annelies; Willekens, Koen; Luik, Anne; Matt, Darja; Grosse, Meike; Heß, Jürgen; Clerc, Maurice; Dierauer, Hansueli; Mäder, Paul.
The interest of organic farmers in adopting conservation agriculture principles, including minimal soil disturbance, permanent soil cover and crop rotation has been growing since the early 2000s. However, currently there is no network for organic farmers practicing conservation agriculture, and a lack of knowledge on how organic farmers implement conservation agriculture in practice. Consequently, few technical references are available for organic farmers when they start applying conservation agriculture practices, in particular on controlling weeds without the use of herbicides. The main objectives of this study were: (1) to explore the diversity of conservation agriculture techniques (i.e., reduced tillage, no-tillage and green manures) practiced among...

Improved Phosphorus Recycling in Organic Farming: Navigating Between Constraints Organic Eprints
Möller, Kurt; Oberson, Astrid; Bünemann, Else K.; Cooper, Julia; Friedel, Jürgen K.; Glaesner, Nadia; Hörtenhuber, Stefan; Løes, Anne-Kristin; Mäder, Paul; Meyer, Gregor; Müller, Torsten; Symanczik, Sarah; Weissengruber, Lina; Wollmann, Iris; Magid, Jakob.
Phosphorus (P) is an essential element for all living organisms. At the current rate of extraction, global reserves of mineable deposits will be exhausted within the next few centuries. This publication aims to summarize the current knowledge on P recycling for organic farming. The evaluation of recycled P fertilizers (RPFs) includes (i) a chemical characterization, (ii) assessment of their plant P availability and added effects in the soil, (iii) life cycle assessments, (iv) a risk assessment of their long-term impacts on soil pollution, and (v) the compilation of other environmental impacts of different treatment approaches to produce RPFs. The highest nutrient recovery rates for P are achieved by rather simple process approaches of P recycling, while...

Meeting P Demand in European organic farms: Is it time to change the Standard? Organic Eprints
Cooper, Julia; Loes, Anne-Kristin; Hörtenhuber, Stefan; Mäder, Paul; Magid, Jakob; Oberson, Astrid; Möller, Kurt.
Organic farming standards regulate allowable nutrient inputs according to the core principles of: reliance on renewable resources, recycling of wastes and by-products of plant and animal origin, and feeding of plants through the soil ecosystem and not through soluble fertilizers, balanced against a goal to produce high quality products with a minimum level of contaminants. These criteria are applied to the list of currently permitted inputs in organic agriculture, known as "Annex 1" of the European Commission Regulation EC No. 889/2008. This list currently excludes some potentially useful sources of societal waste (e.g. some sources of household waste and digestate, sewage sludge), but allows other sources which may pose higher risks according to some...

Nutrient supply to organic agriculture as governed by EU regulations and standards in six European countries Organic Eprints
Løes, Anne-Kristin; Bünemann, Else K.; Cooper, Julia; Hörtenhuber, Stefan Josef; Magid, Jakob; Oberson, Astrid; Möller, Kurt.
Organic farming systems need to replace nutrients exported via farm products, especially phosphorus (P) which may otherwise become depleted in soil in the long term. In Europe, EU regulations for organic production are shaping the farming systems with respect to inputs of nutrients. Permitted off-farm P sources include conventional animal manure, composted or anaerobically digested organic residues, rock phosphate, and some animal residues such as meat and bone meal. The recent proposed revision of EU regulations for organic production (2014) puts less emphasis on closing nutrient cycles and instead aims at minimizing off-farm inputs, to reduce the risk of importing contaminants. This development, which has received little attention from the organic...

Organic farmers’ motivations and challenges for adopting conservation agriculture in Europe Organic Eprints
Casagrande, Marion; Peigne, Joséphine; Payet, Vincent; Mäder, Paul; Sans, F. Xavier; Blanco-Moreno, José Manuel; Antichi, Daniele; Barberi, Paolo; Beeckmann, Annelies; Bigongiali, Federica; Cooper, Julia; Dierauer, Hansueli; Gascoyne, Kate; Grosse, Meike; Heß, Jürgen; Kranzler, Andreas; Luik, Anne; Peetsmann, Elen; Surböck, Andreas; Willekens, Koen; David, Christophe.
Conservation agriculture and organic farming are considered as promising sustainable agricultural system for producing food, while minimizing environmental impacts. Despite an increasing number of experimental data on organic conservation practices and various studies dealing with the adoption of conservation agriculture by farmers, none of those studies have specifically addressed conservation agriculture adoption under organic conditions in Europe. We carried out a survey with 159 farmers located in 10 European countries. These farmers had applied at least two of the following conservation practices: (i) no-tillage, (ii) reduced tillage and (iii) green manures. Each farmer assessed socio-economic, agronomic and environmental motivations and problems for...

Phosphorus availability on many organically managed farms in Europe Organic Eprints
Cooper, Julia; Reed, Eleanor Y.; Hörtenhuber, Stefan Josef; Lindenthal, Thomas; Løes, Anne-Kristin; Mäder, Paul; Magid, Jakob; Oberson, Astrid; Kolbe, Hartmut; Möller, Kurt.
Maintaining sufficient soil phosphorus (P) levels for non-limiting crop growth is challenging in organic systems since off-farm inputs of P are restricted. This study assessed the status of P on organic farms in Europe using soil test results for extractable P. Data was obtained from published literature, unpublished theses, and various national and regional databases of soil test values. Most of the data (15,506 observations) came from field scale soil tests, but in some cases (1272 observations) values had been averaged across a farm. Farm scale and field scale data were analysed separately and the impact of farm type (arable, dairy, grassland, horticulture, mixed, poultry, unknown) was assessed. Soil test results were assigned to P classes from very low...

QLIF Workshop 3: Productivity of Organic and Low Input Systems (Crops) Organic Eprints
Köpke, Ulrich; Cooper, Julia; Petersen, Hanne Lindhard; van der Burgt, Geert J. H. M.; Tamm, Lucius.
A large amount of results on optimising organic and low-input production of crops for commodities such as wheat, apples, tomatoes and lettuce have been generated. However, the gap between the productivity of organic and conventional production systems persists as one of the main issues. In this workshop we want to analyse this gap, assess the impact of the QLIF results on yields and costs, and to spark a discussion on further approaches how to increase productivity and yield stability.

Shallow non-inversion tillage in organic farming maintains crop yields and increases soil C stocks: a meta-analysis Organic Eprints
Cooper, Julia; Baranski, Marcin; Stewart, Gavin; Nobel-de Lange, Majimcha; Barberi, Paolo; Fliessbach, Andreas; Peigne, Joséphine; Berner, Alfred; Brock, Christopher; Casagrande, Marion; Crowley, Oliver; David, Christophe; De Vliegher, Alex; Döring, Thomas F.; Dupont, Aurélien; Entz, Martin; Grosse, Meike; Haase, Thorsten; Halde, Caroline; Hammerl, Verena; Huiting, Hilfred; Leithold, Günter; Messmer, Monika; Schloter, Michael; Sukkel, Wijnand; van der Heijden, Marcel G. A.; Willekens, Koen; Wittwer, Raphaël; Mäder, Paul.
Reduced tillage is increasingly promoted to improve sustainability and productivity of agricultural systems. Nonetheless, adoption of reduced tillage by organic farmers has been slow due to concerns about nutrient supply, soil structure, and weeds that may limit yields. Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management. Shallow refers to less than 25 cm. We found that (1) division of reduced tillage practices into different classes with varying degrees of intensity allowed us to assess the trade-offs between reductions in tillage intensity, crop yields, weed incidence, and soil C stocks. (2) Reducing tillage intensity in...

Shared protocols and data template in agronomic trials Organic Eprints
Cammarano, Davide; Martre, Pierre; Drexler, Dora; Draye, Xavier; Sessitsch, Angela; Pecchioni, Nicola; Cooper, Julia; Willer, Helga; Voicu, Adriana; Hinsinger, Philippe.
Due to the overlap of many disciplines and the availability of novel technologies, modern agriculture has become a wide, interdisciplinary endeavor, especially in Precision Agriculture. The adoption of a standard format for reporting field experiments can help researchers to focus on the data rather than on re-formatting and understanding the structure of the data. This paper describes how a European consortium plans to: i) create a “handbook” of protocols for reporting definitions, methodologies and parameters measured/calculated; and ii) how a data-template for field data was created and will be linked to the “handbook”. The overall goal of the EU-funded project Solutions for Solutions for improving Agroecosystem and Crop Efficiency for water and...

The need to recycle societal P in organic farming systems Organic Eprints
Cooper, Julia.
This factsheet gives a short description of recycled phosphorus (P) fertilisers that may be considered to use in organic farming systems in need of P. Some are currently banned in organic farming, whereas others are permitted. P is an infinite resource, and recycling should be increased. The factsheet is used as a hand-out during workshops in the Improve P Project (https://improve-p.uni-hohenheim.de/ )where stakeholders' opinions about recycled P fertilisers are assessed.
