Summary

In 81 commercial farms in Germany, emissions of the greenhouse gases CO2, CH4 and N2O from crop production have been computed by model-based analyses. The considered influence factors comprise farm structure, mass and energy inputs as well as cultivation methods. A linear correlation was found between energy input and greenhouse gas potential. Due to lower N and energy inputs and also higher C sequestration as a result of humus restoration, the organic farms revealed area-related emissions (785 kg CO2 eq ha-1 a-1) that were 2.75 times lower than the emissions from conventional farms (2165 kg CO2 eq ha-1 a-1).
