Effects of regional variation in climate and SOC decay on global warming potential and eutrophication attributable to cereal production in Norway

Korsaeth, Audun; Henriksen, Trond Maukon; Roer, Anne-Grete - In: Agricultural Systems 127 (2014) C, pp. 9-18

Life Cycle Assessment (LCA) is a common tool for analyzing the environmental footprint of a production chain, such as that of cereal production. In an earlier study, we found that net mineralization of soil organic carbon (SOC) may contribute significantly to the CO2-emissions from a cereal...
