Vascular plants are helpful indicators for the ecological quality. In the context of the Ecological Quality Ordinance they are already used in the utilized agricultural area. Recently, criteria to assess the ecological quality of summer pastures have been discussed. ART has identified the vascular plant taxa, which best represent species richness, the occurrence of Red List species and the occurrence of target and character species following the environmental objectives for Swiss alpine pastures. More than 3500 vegetation relevés were analysed to constitute an indicator list containing 63 taxa. Based on this indicator list and an appreciation by botanical experts the share of alpine pasture reaching floristic quality is currently estimated to be approximately 50 percent.
Arbuscular mycorrhizal fungi are important for healthy soils and crops. A pan-European study shows that plant-protection products adversely affect these fungi, reducing their ability to supply plants with phosphorus via their roots.
A comparison of different methods of winter-wheat fertilisation with nitrogen showed that nitrogen surpluses can be significantly reduced by means of site-specific variable-rate nitrogen fertilisation.

Many tile drainage systems on arable land are in need of renewal. Cantons and stakeholders will now be given a decision-making tool enabling them to assess such areas in detail and to find sustainable solutions.
