The production and composition of horse manure was studied with on farm experiments as well as balance calculations. The results should provide the basis of the revision of the corresponding guide values. Balance calculations were done for riding horses, mares and colts of different age. Animal weight, amount of straw used for litter and hours of activity (riding, work) were used as additional variables. The thus calculated excretion was lower for all categories than according to today’s guide values. The annual production per adult horse was 12-13 t of fresh or around 6 t of decomposed horse manure. The content of the horse manure was influenced more by housing system and straw use than by the different horse categories.
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.
