In three case studies, the spectrum of plant species was evaluated in ecological compensatory areas (extensively and less intensively cultivated meadows, flower strips, hedgerows), in the dominant cultures (winter wheat, intensively cultivated meadows, meadows in orchards) and in the edges of the forests. Habitat specificity, calculated on the base of plant composition in different types of biotopes, allows to assess the proportion of each spatial element. The edges of the forests and the vegetation of their herbaceous margins mainly contribute to habitat specificity in all three regions. In the regions of intensively cultivated grassland or of arable crops, little specificity was found in the typical biotopes (intensively managed meadows and meadows in orchards, fields of winter wheat, respectively), although these biotopes occupy the largest areas. In the region with arable farming, plant diversity in flower strips contribute to high specificity. In the region with mixed cultivation, habitat specificity is more balanced among the differentially cultivated areas. In less intensively cultivated compensatory areas (extensively and less intensively cultivated meadows) higher specificity was observed than in intensively cultivated meadows.
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.
