The rhizosphere effect on soil gross nitrogen mineralization:A meta-analysis
文献摘要：
Rhizosphere effects play crucial roles in determining soil carbon (C) and nitrogen (N) cycling.However,the rhizosphere effect on soil gross nitrogen (N) mineralization (Nmin) has not been quantitatively assessed on the global scale.Hera we performed a meta-analysis of compiled data from 24 publications and 37 species to synthesize the rhizosphere effect on soil gross Nmin and its influencing factors.We found that the rhizosphere effect significantly enhanced soil gross Nmin by 81％ on average.Such rhizosphere effect was significantly higher in woody species than in non-woody species,and higher in ECM (ectomycorrhizal) associated species than in AM (arbuscular mycorrhizal) associated species.Moreover,the variations of the rhizosphere effect on soil gross Nmin were correlated with those on soil C mineralization,phenol oxidase activity and root biomass rather than with other plant (growth form and mycorrhizal association) and climatic (mean annual temperature and precipitation) factors.These results support the 'microbial activation'and 'microbial N mining'hypotheses of rhizosphere effects and indicate the coupling of soil C and gross N mineralization in the rhizosphere.Overall,these findings provide novel insights into the rhizosphere effect on soil gross Nmin among plant growth forms and myconhizal associations,and improve our mechanistic understanding of soil N dynamics in the rhizosphere.
