Objectives

The aim of the OG is the production of high quality fruits with a simultaneous reduction of fertilizer use and the environmental impact on soil and water resources. The applicability and effectiveness of strategies to reduce nutrient inputs on drained areas is to be tested. These will at first be investigated by water-side measures and secondly by testing the nutrient concentration and the material displacement on drained soil. A combination of a reactive dig and controlled drainage is used to test the reduction effect on nitrogen and phosphorus. A reactive drainage ditch is a dewatering unit in which the nitrate removal by denitrification processes is stimulated by the supply of organic material.
