The effect of tillage prctices on a leek crop's nitrogen utilization from a grass-clover sward Organic Eprints
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.

SOIL QUALITY AND CROP PRODUCTIVITY AS AFFECTED BY DIFFERENT SOIL MANAGEMENT SYSTEMS IN ORGANIC AGRICULTURE "TILMAN-ORG Session" Organic Eprints
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.

Effect of Compost versus Animal Manure Fertilization on Crop Development, Yield and Nitrogen Residue in the Organic Cultivation of Potatoes Organic Eprints
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...
