The present study investigated the interactions among nitrogen transformation and soil bacteria along the direction of diffusion of hole-applied urea. To this end, a lab incubation trial was conducted on sandy loam and silty loam soils. Soil bacterial communities were analyzed via 16S rRNA high-thro...
