The teaching and research unit Gladbacherhof at the Villmar site primarily serves research and teaching in the field of organic farming.
The task of the Gladbacherhof is to produce food and animal feed in a way that is as environmentally and resource-friendly as possible. This requires management that is more strongly based on the internal nutrient cycles on the farm and uses self-regulating forces on the farm as far as possible. This includes the preservation and creation of a richly structured cultural landscape with its ecologically valuable animal and plant communities. The focus of the study is on crop rotation and soil cultivation in organic farming, on ways to improve the baking quality of wheat, on the cultivation of legumes and on long-term effects on the nutrient balance of organically farmed arable land.
