Drivers of Biological Nitrogen Fixation in Paddy Soils: Linking Soil Properties, Diazotrophic Communities, and Nitrogen Dynamics
Biological Nitrogen Fixation (BNF) is a sustainable alternative to synthetic fertilizers that deliver bioavailable nitrogen to rice fields. However, the spatial variability of BNF and the relative contributions of soil physicochemical properties and trace-element availability remain poorly understood in long-term culti...
