Development of soil fertily, plant production and biodiversity after conversion of the experimental farm in Trenthorst/ Wulmenau towards organic farming in 2001
Agricultural ecosystems are mirroring their management. Maintaining farming practices will drive them in direction of a steady state, provided that climate and environmental conditions remain constant. Changes in cultivated crops, crop rotations, fertilisation, use of pesticides, soil tillage, grazing, livestock keeping and density and other management changes will influence ecosystems development. A long term farming system comparison on these questions is established in Trenthorst. The development of soil parameters, yields and qualities of plants and biodiversity is analysed since conversion of the site to organic farming in 2001.
