According to the serious situations of soil organic content reduced year by year,and the ability of soil water preserving decreased,we studied the carbonate chernozems remediation technique through cow dung,green manure,and formulated fertilization.The result showed that adoption of such techniques as adding organic manure such as cow dung,green manure,and formulated fertilization could significantly improve the physical characters of the carbonate chernozems.On the basis of normal fertilization in the local regions,adding organic manure and formulated fertilization increased the field water preservation rate by 6.9%~17.4%,increased the soil porosity by 7.4%~11.8%,decreased the soil volume weight by 0.09~0.1 g/cm3 and increased the corn yield by 10.3%~16%.The effect of green manure application was the best in improving the water preserving ability of carbonate chernozems. The effect of continuous applying organic manure to improve degenerated carbonate chernozems was significant.
