Summary

In a field trial established in 1994 by the foundation „Stiftung Ökologie und Landbau“, different primary tillage systems are being tested on their influence on root and shootgrowth of cereals. The tillage implements are : mouldboard plough, two layer plough and layer cultivator. Investigations oriented on soil physical parameters ( e.g. aggregate stability ), root parameters ( e.g. root-length-density ), shoot growth ( e.g. dry matter, yields) and laboratory analysis ( e.g., P, K Ct/Nt contents ). These parameters were also tested for the weeds, that can strongly compete with the crops, especially in reduced tillage systems. The results of the investigations combined with knowledge obtained from previous work and literature are being interpreted in order to assess the possibilities and limits of the reduced primary tillage intensity under given field conditions.
