Red clover (Trifolium pratense L.) had a higher content of protein and of digestible organic matter than orchard grass (Dactylis glomerata L) during the first, second and third growth cycles. With advancing maturity, the protein content and the digestibility decreased in both species. Red clover showed approximately 40 % less cell wall content than orchard grass. The principal difference in the cell wall was the small amount of heicellulose in red clover. The content of formononetin varied between varieties from 5.4 to 9.6 g/kg DM. The formononetin is supposed to be responsible for the oestrogenic effect of red clover.

The root knot nematode (RKN) Meloidogyne incognita causes damage in field and greenhouse crops. Agroscope researchers have developed a new screening test to identify bacteria that antagonise this agricultural pest.
With CULTAN fertilisation, nitrogen is injected into the soil as an ammonium solution. Multi-year trials conducted by Agroscope show that this method reduces nitrogen leaching by an average 38% without negatively affecting yields.
Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.
