The effect of ecological measures in agriculture on the phosphorus contamination of waters caused in particular by surface runoff was investigated in the catchment area of the Lippenruti Brook in the canton of Lucerne. Within the scope of this investigation spanning 270 different fields, site, cultivation and dung spreading factors were examined and placed in a causal connection with the measurements made in the brook. In comparison to the phosphorus contamination of the brook at the beginning of the nineties, first results lead to assume a maximal reduction of 19 % of the contamination caused by agriculture.
Grass-based beef production is markedly less productive than intensive year-round indoor-housing system-based production. Agroscope experts therefore studied how grass-based farms can produce both economically and in an ecologically sound manner.
Orchard crop spraying using unmanned aerial spraying systems commonly referred to as drones can lead to drift, posing a risk to residents and bystanders. The study shows that the risks arising from this are taken into account by the current registration process.
Trials conducted by FiBL have shown that conversion to organic farming also promotes endangered Red List species such as the carabid beetle species Amara tricuspidata. This species and other species consume seeds of forbs and grasses and thus supports natural weed control.
