Spatial variation evaluation of cultivated land quality from the perspective of crop rotation for a typical lateritic red soil farming area in south China

Characterizing the spatial variation of cultivated land quality based on crop rotation pattern could provide a basis for improving regional cultivated land quality through optimizing crop rotation management. To this end, we constructed a crop rotation system classification for the typical lateritic...
