Woody peat input or not-induced loss of straw-derived nitrogen are mainly regulated by bacterial taxa and denitrifying functional genes in saline and non-saline soils

Revealing the biological mechanisms of the loss of straw-derived nitrogen (N) is crucial for the prediction of eco-friendly and cost-effective straw returning to the field, however, there is a dearth of studies on this topic, especially on the comprehensive comparison under woody peat-amended and non-amended conditions in saline and non-saline soils.
