Sulfate leaching was determined with following crops: winter wheat, spring wheat, winter oak, rape, corn, potato, sugar beet and grass-clover mixture. Under the conditions of the lysimeter experiment at Zurich-Reckenholz (1000 mm annual precipitation, 400 mm from October to March), green manure before potato, corn and sugar beet – mineral sulphur fertilization and the crop sequence was the most important factor for sulfate concentration in the leaching water at 2.5 m depth. Concentration of sulfate was not as much seasonally determined as the one of nitrate. Sulphur leaching was 50 to 90 kg S/ha*year depending on crop and fertilization. Yearly sulfur-balance showed a mean loss of 70 kg S/ha which in farming-systems without organic manure should partially be compensated by adequate choice of fertilizer.
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.
