The Department of Ecology of Tropical Agricultural Systems is involved in the NOcsPS collaborative project at the University of Hohenheim. The aim of the BMBF-funded project is the development and analysis of a new cultivation system without chemical-synthetic pesticides but with optimized use of mineral fertilizers with innovative cultivation and utilization measures from the perspective of all relevant fields of agricultural science. At the same time, the opportunities and effects of such a radical changeover are to be analyzed at the level of individual plants, fields, farms and regions. Our department focuses on studies on the biodiversity of insects and spiders in the NOcsPS cropping system. https://nocsps.uni-hohenheim.de/en/english ; https://nocsps.uni-hohenheim.de/en/cp23-biodiversity-nocsps
