Effect of crop residue incorporation on soil organic carbon and greenhouse gas emissions in European agricultural soils

摘要: Soil organic matter (SOM) improves soil physicochemical and biological properties, the sequestration of carbon in SOM may mitigate climate change. (SOC) often decreases intensive cropping systems. Incorporation crop residues (CR) be a sustainable management practice to maintain SOC levels increase fertility. This study quantifies effects CR incorporation on greenhouse gas (GHG) emissions (CO2 N2O) Europe using data from long-term experiments. Response ratios (RRs) for GHG were calculated between removal. The influence environmental zones (ENZs), clay content experiment duration RRs was investigated. We also studied how yields correlated. A total 475 derived 39 publications. increased by 7% following incorporation. In contrast, subsample cases, CO2 six times N2O 12 higher ENZ had no significant RRs. For concentration, soils with >35% showed 8% compared contents 18 35%. As progressed, RR concentration increased. emissions, significantly greater experiments <5 yr 11–20 yr. No correlations found yields, but differences sites durations detected. suggest that long residue is win-win scenario under continental climate. conclude important maintaining SOC, its should taken into account as well.
