Plant species richness, plant assemblages, red list plants and the fulfilment of quality requirements with respect to ecological quality payment system (ÖQV) were investigated for different mountain meadow types in the Swiss Alps. The overall quality of extensively managed meadows was slightly but not significantly higher than that of low-intensive meadows. Only intensively managed meadows clearly differed from the less intensively or extensively managed meadow types. The mean number of plant species per meadow type declined with increasing management intensity. Dry sites harboured slightly more species regardless of the management type. Other factors such as slope, altitude, accessibility (distance from farmyard) or meadow size did not significantly influence the species richness of meadows. Compared to investigations in the Swiss lowlands, the extensively or less intensively managed mountain meadows showed higher ecological quality.
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.
Ammonia emissions from the Swiss farming sector have scarcely declined over the past 20 years. This is because the factors leading to either an increase or decrease in emissions have for the most part cancelled each other out between 2000 and 2020.
