英文摘要Anthropogenic activities, particularly land use change and management practices, alter the global nitrogen (N) cycle. As a central part of the global N cycle, soil N supply from net N mineralization (NNM) and net nitrification (NN) contributes to over 50% of crop N uptake. However, how global land use changes impact soil N supply and potential N loss remains elusive. By compiling a global data set of 1,782 paired observations from 185 publications, we show that land use conversion from natural to managed ecosystems significantly reduced NNM by 7.5% (-11.5, -2.8%) and increased NN by 150% (86, 194%), indicating decreasing N availability while increasing potential N loss through denitrification and nitrate leaching. In contrast, reversing managed to natural ecosystems significantly increased NNM by 20% (9.7, 25.4%) and decreased NN by 89% (-125, -46%), indicating increasing N availability while decreasing potential N loss. Structural equation modeling revealed that land use change induced changes in soil properties, including organic matter content, bulk density, microbial biomass and pH, and anthropogenic activities, including application of ammonium-based fertilizers and manure, were the most important factors regulating NNM and NN. The land use change effect was the strongest in tropical and subtropical regions, where NNM was negatively affected and NN positively affected by land use change. Our findings indicate that increasing soil organic matter content and enhancing soil structural development post land use change can boost soil N supply and reduce the risk for N loss.
