Additional information

Conventional crop rotations usually consist of 2-3 crops, two of which are usually cereals. These crops are grown with a high level of synthetic nitrogen fertiliser, which requires a high energy input. The use of legumes in the crop rotation cycle, on the other hand, can help to stabilise or even improve soil fertility, bind carbon (C), fix N, and thus reduce greenhouse gas emissions.



The introduction of cover crops into crop rotation as green manure also increases the organic carbon content (SOC) in the soil without sacrificing yield.



Within the SOLMACC project, the cultivation of

• Grain legumes (such as soya, beans, winter peas and lupines into their crop rotation systems).

• Forage legumes (enriching the proportion of N fixing plant species in the current green manure mixture) and

• grass-legume leys

was introduced / expanded. The established cooperation models between livestock/biogas farms and stockless farms led to win-win situations for both farms - environmentally but also economically
