Abstract

In a long-term tillage experiment in Mecklenburg-Western Pomerania high penetration resistances up to 3,5 MPa were found in 30–45 cm soil depth as a result of continuous ploughing. A no-till-system showed a gradual increase over 0–60 cm soil depth. Tillage with plough, cultivator or rotational tillage (changing of plough and cultivator) caused different effects on dry density, poro­sity, water and air content in the upper soil (0–30 cm). Under the existing site conditions, yields were not compromised by a reduction of the tillage intensity. The data suggest that rotational tillage may have beneficial effects on physical soil properties, similar to the effects observed with continuous no-till regimes.
