| Abstract: | At present the content of organic matter in the cultivated soil is at 5.30 g/kg ~ 24.21 g/kg, averaging 14.65 g/kg. Compared with that measured during the second national soil survey, the content of organic matter shows a rising trend. The content of humin C accounts for about 53 % ~ 70 %, averaging 61 %, and that of humic acid C for about 39 % of organic matter C. |
