Abstract:Efficient utilization of check-dam-induced land is one of the important ways to keep the sustainable development of the conversion of arable land into grassland or forestland on the Loess Plateau.An investigation was launched to check soil moisture,organic matter,total nitrogen,and total phosphorous,as well as soil available nutrients in the soil profiles of the check-dam-induced land in Zhifang watershed,the first tributary of Jinghe River.Results showed that land types,in terms of the level of soil available nutrients in different types of lands,followed the descendant order of long-term check-dam-induced land,short-term check-dame-induced land,terrace,and sloping wasteland.The discrepancy of soil organic matter,total nitrogen,total phosphorous and available nutrients among soil layers in the profiles of check-dam-induced lands was insignificant.The supply ability of soil available nutrients demonstrates the sustainability and the sediment in the check-dam-induced lands readily enriches available nutrients,suggesting that there is the great potential for the growth of crop yields.
