In a national evaluation program, the effects of different field margins on the carabid fauna were investigated by using funnel pitfall traps. 109 cultivated and non-cultivated (51 field margins) sites were chosen for a biodiversity evaluation, in which carabids were used as indicators. The data of the first investigation year shows that the abundance and species diversities can greatly varied within the same habitat and beetween the different sites. Certain field margins such as sown wild flower strips can significantly contribute to a richer and more abundant carabid community in arable land. Endangered species of the Red List were in generall rarely found, they mainly occured in non-cultivated habitats and low-input grassland. A multivariate analysis showed that site characteristics such as plant diversity, the type of habitat and on the landscape level the number of different habitats and the share of cultivated land can significantly alter the carabid fauna.

Agroscope researchers tested the FAO method for assessing the agroecological status of farms in Switzerland for the first time, demonstrating the advantages of a holistic evaluation as well as the limits of the tool.
In wheat crops, pesticides can be used more sparingly without sacrificing cost-efficiency. With oilseed rape the situation is more difficult, since the reduced yields are not offset by higher revenues. These are the findings of the analysis of the first two harvest years of the PestiRed project.
Soil samples can be measured directly in the field by means of spectroscopy. Agroscope researchers have tested mobile devices and shown how to make the best use of them.
