Regional simulation of nitrate leaching potential from winter wheat-summer maize rotation croplands on the North China Plain using the NLEAP-GIS model

•Regional simulation of nitrate leaching from NCP croplands was done using NLEAP-GIS.•Spatial-temporal variation of nitrate leaching in North China Plain was quantified.•Water input, fertilizer and soil jointly affect N leaching spatial-temporal pattern.•Optimal fertilizer N rates were recommended f...
