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 Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management.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...

As conservation agriculture and organic farming are currently considered as environmentally friendly options for producing food, this study explores the motivations and problems of organic European farmers that apply at least two of the following techniques: (i) no-tillage, (ii) reduced tillage and/or (iii) green manures conservation practices. We carried out a survey about motivations and problems of 159 farmers located in 10 European countries with a questionnaire with closed-ended questions. Data were analysis with a principal component analysis followed by clustering to identify groups of farmers that share the same type of motivations and problems. The most important motivations are related to soil preservation concerns and problems are mainly linked...

Effect of Compost versus Animal Manure Fertilization on Crop Development, Yield and Nitrogen Residue in the Organic Cultivation of Potatoes
Provedor de dados: 21
Autores: Willekens, Koen; De Vliegher, Alex; Vandecasteele, Bart; Carlier, Lucien.
Organic farmers in Flanders use manure from extensive conventional livestock systems due to a lack of animal manure from organic producers. The research question was if on-farm prepared compost mainly consisting of vegetal residues can be a good alternative. A long-term fertilization trial with a 4-year crop rotation of maize - potatoes - spring barley - red clover is carried out on two fields with a time difference of one year. The fertilization treatments are on-farm prepared compost, applied as a single dose and a double dose, farmyard manure, slurry and slurry combined with composted municipal waste. This paper concerns the experimental results of the potato crop in 2006 and 2007. The nitrate content of the plant juice was monitored and the potato...

SOIL QUALITY AND CROP PRODUCTIVITY AS AFFECTED BY DIFFERENT SOIL MANAGEMENT SYSTEMS IN ORGANIC AGRICULTURE "TILMAN-ORG Session"
Provedor de dados: 21
Autores: Willekens, Koen; Vandecasteele, Bart; De Vliegher, Alex.
A multi-year trial was conducted to compare soil management strategies (tillage and fertilization) with regard to their effect on crop performance and soil quality. Two soil management systems were assessed. Farm compost application was combined with reduced non-inversion tillage, whereas animal manure was incorporated by conventional tillage with a moldboard plough. With regard to soil quality, a reduced tillage practice in combination with compost application seemed to be favorable for soil quality of the surface layer in the short term. With regard to crop productivity, an effect of soil management strategy is less clear and dependent on a seasonal variation of growth circumstances.

Composting leaflet – agroecological approach at your farm
Provedor de dados: 21
Autores: Jamart, An; Willekens, Koen.
This leaflet will help organic farmers to overcome barriers and get started with on-farm composting. With minimal additional work, vegetable and arable farmers can upgrade crop residues to compost. Compost application can be integrated in the crop rotation and combined with reduced tillage. Also on livestock farms composting can offer added value. Composted manure is more stable, because the decomposition process has already partly taken place. By mixing other materials in the manure, the N/P ratio in the compost can be adjusted. Moreover, composting kills off the pathogens in manure. This leaflet gives an overview of the characteristics of good quality compost and the different steps of making compost. It provides an update of recent compost research in...

The effect of tillage prctices on a leek crop's nitrogen utilization from a grass-clover sward
Provedor de dados: 21
Autores: Willekens, Koen; Van Gils, Bert; De Vliegher, Alex; Delanote, Lieven; Beeckman, Annelies; Vandecasteele, Bart.
Adopting conservation agriculture practices in organic agriculture involves some risks and challenges. Nitrogen availability from a grass-clover ley for the subsequent leek crop was clearly affected by mode and timing of destruction of the grass-clover sward. Minor differences were found between a reduced tillage practice and conventional ploughing.

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,...

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...

Bodemmicrobiologie als indicator voor bodemkwaliteit?
Provedor de dados: 21
Autores: Willekens, Koen; Debode, Jane.
De Rusch-test is een relatief goedkope en eenvoudige microbiologische test die werd ontwikkeld door dokter en wetenschapper Hans Peter Rusch uit Duitsland, maar tot hiertoe weinig toepassing gekend heeft. De doelstelling van dit project was na te gaan of de Rusch-test kan dienen als indicator voor een goede bodemkwaliteit en of deze eenvoudige test, voor de teler interessante info kan opleveren in verband met de gevolgde of te volgen teeltpraktijk. Hiervoor werd in het eerste luik van het project, op verschillende biologische percelen in Vlaanderen, gedurende twee jaren, de bodemmicrobiologie door middel van drie verschillende methodes bepaald (Rusch, PLFA en DGGE). Naast het analyseren van de bodemmicrobiologie, werden tijdens het eerste jaar ook een...

How organic farmers practice conservation agriculture in Europe

Autores: 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...
