The quantity of compost produced in Switzerland has been assessed, and the quality of individual composts has been determined and compared to the legal standards describing a minimal quality of compost. A last comparable study has been made in 1988. Today, more than 450’000 tons of fresh material are composted in more than 200 compost producing plants. One third of these plants did not analyse the quality of their compost until now. The remaining plants usually fulfill the requirements of limit values for heavy metals in compost without problems. There is an important lack in self-control of the hygienic quality of the compost. Hardly one quarter of plants fulfill this requirement. The content of litter contaminants in compost does not seem a big problem in most of the composting plants.
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.
