Efficient use of the Loess Plateau dammed land is consolidate the results of returning farmland to forest and grassland one of the important means.the test is base of the dammed land of Zhifang Valley in Jin river,and analyzed the soil moisture,soil level between the organic matter,total nitrogen,total phosphorus and available nutrient,such as differences in physical and chemical properties.The results showed that with the close crop of available nutrient content of the average performance for advanced age dammed land> lowed dammed land > terrace> wasteland slopes;and from the soil profile in different parts of soil,between the level of organic matter,total nitrogen,total phosphorus and available nutrient,The discrepancy was less,in the soil available nutrient supply capacity of more persistent,dammed land silt and sediment accumulation more nutrients available,and showed that the dammed land have greater potential to increase production.
