Greenhouse gas balance of bioenergy cropping systems under the environmental conditions of Schleswig-Holstein

摘要

A 2-year field trial was conducted at two sites in Schleswig-Holstein, northern Germany, to perform a GHG balance to quantify and evaluate the impact of cropping system (maize monoculture, maize-wheat rotation and permanent grassland), nitrogen (N) level and N type. Considering the whole production chain, maize monoculture revealed a higher GHG mitigation potential than the other systems investigated. The comparison of fertiliser types showed less pronounced differences in GHG emission, whereas considerable site effects were observed.
