Summary translation

Ploughing is usually the primary soil tillage in organic farming due to weed control and N mineralisation. The aim of the study was to determine the impact of temporary and permanent non-plough tillage. Two field trials were established in 1997 under conventional conditions and converted to organic farming in 2012 and 2013. The three treatments were conventional ploughing (CP), reduced ploughing (RP) and conservation tillage (CT) with no ploughing.
The results differed due to the precipitation amount. At the station with higher precipitation, yields in the CT plots were significantly lower for all four cash crops compared to the other two treatments due to high weed pressure. At the other station, over the whole crop rotation, the yields of the RP and CT treatments were 101% and 97%, respectively, of the yields for the CP treatment. Crunchpoint is the no ploughing after the grass-clover ley in organic farming.
