| Abstract: |
| Study was made on soil physical and chemical properties of 14 pieces of abandoned cropland with different years of abandonment.The results showed that soil bulk density was descending and the texture was improving;soil organic matter content, CEC, total K, hydrolyze N and available K were increasing during vegetation restoration, while soil salt content and soil pH value were decreasing.It meant soil physical and chemical properties were improving during the vegetation restoration.In addition, plant biomass correlated closely with soil organic matter content, CEC, total N, total K, hydrolyze N, available K, pH and soil bulk density.It showed that soil and vegetation interacted. |
