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

Climate impact of organic production in the Netherlands Organic Eprints
Sukkel, Wijnand.
All agricultural activities have an impact in terms of greenhouse gases and energy use, and organic agriculture is no exception. The Dutch organic sector strives to use sustainable energy and keep its climate impact as low as possible. To facilitate organic farmers, Wageningen UR and Louis Bolk Institute carry out a variety of research aimed specifically at energy use and greenhouse gas emissions. The report contains sector facts, sector aspirations, current affairs and research projects.

Combination of Spatial and Temporal Diversification in European Cropping Systems Organic Eprints
Corre-Hellou, Guénaëlle; Sukkel, Wijnand; Schmaedeke, Frank; Arlotti, Donatienne; Toque, Clotilde; Vandevalle, Aline; Jensen, Erik; van Apeldoorn, Dirk; Krauss, Maike; Campanelli, Gabriele; Lefèvre, Amélie; Dauber, Jens; Tebbe, Christoph; Cuperus, Fogelina; Canali, Stefano.
There is a lack of results on the advantages and limitations of combining different crop diversification strategies both in time and space, which makes it difficult for famers and advisers to find relevant information for the transition towards more diversified cropping systems. A network of ten field experiments (diverIMPACTS project) was built across seven European countries, covering a range of pedo-climatic conditions and different farming systems: arable and vegetable systems under both conventional and organic management. Each field experiment tests one or several diversified cropping systems, which combine three diversification strategies with low input practices. These diversified cropping systems are compared to reference systems, which are less...

Dutch soil management and soil fertility Organic Eprints
Sukkel, Wijnand.
The organic sector depends heavily on its soils. In the Netherlands, relatively little acreage is available per farm compared to other countries. This means that the soil has to be kept in optimal shape for production, be it vegetables, cereals, potatoes or animal feed and grassland. To facilitate organic farmers, Wageningen UR and Louis Bolk Institute carry out a variety of research aimed specifically at soil management and soil fertility. The report contains sector facts, sector aspirations, current affairs and research projects.

Organic open field cultivation in the Netherlands Organic Eprints
Sukkel, Wijnand.
The arable farming and field vegetable cultivation sector is a significant part of the organic agricultural sector in the Netherlands. The sector produces not only vegetables for human consumption, but also organic animal feed such as maize an cereals. To facilitate organic farmers, Wageningen UR and Louis Bolk Institute carry out a variety or research aimed specifically at organic arable farming and field vegetable production. The report contains sector facts, sector aspirations, current affairs and research projects.

REDUCED TILLAGE AND COVER CROPS IN ORGANIC ARABLE SYSTEMS PRESERVES WEED DIVERSITY WITHOUT JEOPARDISING CROP YIELD Organic Eprints
Barberi, Paolo; Aendekerk, Raymond; Antichi, Daniele; Armengot, Laura; Berner, Alfred; Bigongiali, Federica; Blanco-Moreno, José Manuel; Carlesi, Stefano; Celette, Florian; Chamorro, Lourdes; Crowley, Oliver; Döring, Thomas; Grosse, Meike; Haase, Thorsten; Hess, Jürgen; Huiting, Hilfred; José-Maria, Laura; Klaedtke , Stéphanie; Kranzler, Andreas; Luik, Anne; Peigne, Joséphine; Sukkel, Wijnand; Surböck, Andreas; Talgre, Liina; Sans, Francesc Xavier.
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.

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...

Soil quality – A critical review Organic Eprints
Bünemann, Else K.; Bongiorno, Giulia; Bai, Zhanguo; Creamer, Rachel E.; de Deyn, Gerlinde; de Goede, Ron; Fleskens, Luuk; Geissen, Violette; Kuyper, Thom W.; Mäder, Paul; Pulleman, Mirjam; Sukkel, Wijnand; van Groeningen, Jan Willem; Brussaard, Lijbert.
Sampling and analysis or visual examination of soil to assess its status and use potential is widely practiced from plot to national scales. However, the choice of relevant soil attributes and interpretation of measurements are not straightforward, because of the complexity and site-specificity of soils, legacy effects of previous land use, and trade-offs between ecosystem services. Here we review soil quality and related concepts, in terms of definition, assessment approaches, and indicator selection and interpretation. We identify the most frequently used soil quality indicators under agricultural land use. We find that explicit evaluation of soil quality with respect to specific soil threats, soil functions and ecosystem services has rarely been...

Telen bij lage fosfaatniveaus in de biologische landbouw; achtergronden en literatuurstudie Organic Eprints
Timmermans, B.G.H.; Sukkel, Wijnand; Bokhorst, J.G..
Fosfor bevindt zich in anorganische en organische vorm in de bodem. Beide lijken van belang voor plantenvoeding, maar over de verhouding waarin deze bronnen een rol spelen voor akkerbouw op kalkhoudende klei en zavelgronden is nog onvoldoende bekend. De huidige bodemanalyses worden verbeterd, maar er wordt vooral anorganisch fosfaat geanalyseerd. Planten hebben veel mechanismen om fosfaat op te nemen, maar het speelt zich allemaal heel dicht bij de wortel af en de meeste potentieel beschikbare fosfaat is daarom toch niet effectief beschikbaar. De bodemstructuur en beworteling bepalen het deel van de bodem dat toegankelijk is. Verzorging van de bodemstructuur en stimulering van het bodemleven zijn belangrijke maatregelen om bij lage fosfaatniveau ’s te...
