The field experiment «Kyoto-Wiese» in Oensingen (CH) shows that the conversion of arable land to intensively managed permanent grassland leads to an increase in the soil C-content of around 1.5 tons per hectare and year, provided that a sufficient amount of N-fertilizer is applied. This sequestration of carbon corresponds roughly to the yearly emission from gasoline of a passenger car. On the intensively managed field, 16 % of the saved CO2 emissions are compensated by emissions of nitrous oxide (N2O). The extensively managed field shows a similar yield as the intensive plot, but an annual release of CO2-C of around 0.5 tons per hectare with only minor N2O emissions. The reason for this difference is most likely a high rate of mineralization of soil organic matter. The extensively managed system approaches a new equilibrium with most likely a reduced soil organic matter content. Therefore, at the field scale management has a major influence on the greenhouse gas budget of grasslands.
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.
