Introduction of grass-clover crops as biogas feedstock in cereal-dominated crop rotations. Part II: effects on greenhouse gas emissions.

摘要: In an analysis of climate effects, increased soil organic carbon will have a dual effect due to both fertility and sequestration. Even so, changes are neglected in many crop production LCAs. the present study, introduction grass-clover crops cereal-dominated was evaluated. The were used for biogas production, digested residue recycled farm as biofertilizer. A shift from rotation integrated food one or two years feedstock would result avoided emissions 2-3 t CO2-eq. ha-1 a-1. Integrated energy this case improve content at same time resulting considerably decreased greenhouse gas cultivation system. (Less)
