The use of powerful machines in different soil tillage systems.

Soil is the most important production basis of the farmer. To provide a correct and gentle treatment, several improvements in technique and production systems were developed. Especially the heavy loads in harvesting represent a hazard to soil compaction. Modern terra tires and adequate chassis facilitate a gentle transmission of heavy loads to the soil. Conservation tillage improves the trafficability of the soil especially under humid conditions. A high loaded single passing of the soil must not lead to compaction in the subsoil. This is reflected by the soil physical parameters and the yield of wheat.
