Auswaschungsverluste unter biologischer und konventioneller Bewirtschaftung

Summary in the original language of the document

In this project, located at Winklhof, a comparison between organic and conventional farming is done. The field trial combines a crop rotation with two levels of fertilisation intensities (one is 1.0 LU ha- and the other is 1.8 LU ha-1). The fertilisation-systems are stable-manure and liquid manure, the treatments were done organically. The aim of this project is to find out which production system is better for the environment in spite of crop yield, product quality and leaching losses. The last parameter was measured in lysimeters. A high amount of yearly precipitation could account the high amount of seepage water. Consequently the leaching losses of both production systems could be compared.
