| Abstract: | Under the frame of national cropland classification zones,the cropland in Jiangxi Province was classified into 4 sub-zones by induction method and experts' experience.The cropland soil ferility evaluation system was established by modifying method,based on soil genus data from soil survey in 1980 and complementary soil survey in 2005.Using soil genus as evaluation unit and numerical evaluation method,the cropland in Jiangxi Province was classified into 9 grades,37.8% of which was in grade 4. |
| Keywords: | cropland soil fertility evaluation system soil fertility grade soil genus |
