Humusmenge in der Ackerkrume nach langjährig differenzierter Intensität der Grundbodenbearbeitung

The aim of the present study was to investigate the impacts of different tillage intensity on the quantity of soil organic matter in topsoils of seven long-term trials. Tillage intensity was found to affect both bulk density and Ct-contents, whereas total C quantity did not differ significantly between tillage treatments in all trials even though a high C accumulation in the reduced tillage system was visible in one trial. As for humus balancing, a consideration of tillage intensity is not supported by these results
