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.
Agroscope has developed a scoring system for plant protection in vegetable crops. The system enables the creation of incentives for reducing the use and environmental risks of plant-protection products and promoting preventive and non-chemical measures.
Many consumer goods contain activated carbon, which can be contaminated with pollutants like polycyclic aromatic hydrocarbons (PAHs). Agroscope showed that current analytical methods and legal bases used to address PAH content are incomplete.
Dry summers can see a loss of up to 25% of total Swiss roughage production. This is because grassland yields are strongly correlated with summer drought, as shown by a new analysis conducted by Agroscope and the Swiss Farmers’ Union.
