Responses of soil microbiome to nitrogen input on eroded slope farmland in Southwest China

Maintaining soil productivity and sustainability remains a challenge in the face of a changing global agricultural framework, which includes the primary threat of soil degradation in many regions. Although soil erosion contributes to land degra- dation, how reductions in fertiliser nitrogen (N) affect erosion and soil microbial communities in sloped farmland remains unclear. In this study, effects of reduc- tions in fertiliser N from 300 kg ha −1 (N1) to 225 kg ha −1 (N2), 150 kg ha −1 (N3),...
