| The aim of this study was to evaluate the interaction between yield levels of nonleguminous crops and soil organic matter (SOM) under the specific conditions of organic and conventional farming, respectively, and to identify implications for SOM management in arable farming considering the farming system (organic vs. conventional). For that purpose, correlations between yield levels of nonlegume crops and actual SOM level (Corg, Nt, Chwe, Nhwe) as well as SOM-level development were examined including primary data from selected treatments of seven long-term field experiments in Germany and Switzerland. Yield levels of nonlegume crops were positively correlated with SOM levels, but the correlation was significant only under conditions of organic farming, and... |

| The increased importance of organic farming in recent years, has led to a diversifica-tion of production systems. Since 1998 different farming systems were compared in a long-term field trial at the university of Halle-Wittenberg. The systems simulated either arable or mixed farming with various tillage treatments. In the first rotation the crop yields showed a clear response to the different farming systems. The balances of organic substances were mainly affected by the amount of organic fertilisers applied, whereas the nitrogen balance was influenced by the nitrogen fixation capacity of the clover-lucerne sward. |
