| Within an interdisciplinary approach 24 groups of 20 pigs each were fattened outdoors to examine and calculate the nutrient inputs and their distribution in soils in relation to several management strategies. Management strategies varied in diets, field crops to pigs, static or mobile installation units like huts, troughs, and sun shelters. Stocking rates were adapted to the regulations of the Bioland organic farming associations, which limit the nutrient input to a maximum nitrogen load of 112 kg ha -1 a-1 or 10 fattening pigs ha-1 a-1, respectively. The results were discussed with regard to the nutrient accumulation in soils and leaching of nitrate into groundwater. Recommendations in relation to management strategies and integration of outdoor pig... |

| On the Hessian state domain Frankenhausen near Kassel the project “The Integration of Nature Conservation into Organic Farming” (supported by the German Federal Agency for Nature Conservation with funds of the Federal Environmental Ministry) aims to support biodiversity not only by restoring biotopes on the farmland. The focus lies on measures to enhance the diversity on the arable land and the pastures of the farm. A participatory approach is striven for, in which the scientists and planners take the role of a companion catalyst or moderator. |
