Intensive soil tillage in conventional potato cropping increases the risk of erosion and leaching of nitrate. Direct mulch planting of potatoes was developed to reduce this risk. Ridges and covercrops are established in August after harvest of the preceding cereal crop. In the following spring potatoes are plated without any soil tillage. The results of a FAL-trial series (1995-1999) show the chances of the new cultivation system. Early weed control is necessary because of the presence of established weeds and germinating weeds. Heavy soil with high bulk density influences negatively the quality of tubers and reduces the yield. In light soils however quality and yield almost comparable to conventional cropping is reported by other authors.
Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.
Swiss vineyards are often small and arranged in a mosaic of separate plots and management practices. Therefore, it can be assumed that spray drift from conventional to organic vineyards occurs regularly. Nevertheless, no pesticide residues are detected in most organic wines.

Red clover is one of the most important legumes in European forage production. In a multi-year field trial, researchers tested Europe’s largest collection of different red clover accessions at five European locations.
