Aims Intercropping promoted land productivity and be performed worldwide. This study aimed to assess the effect of intercropping on soil dissolved organic carbon (DOC) and its nitrogen (N) regulation. Methods The potato was monocropped and intercropped with maize under four N levels (0, 62.5, 125 an...
