%X The availabilities of nitrogen,phosphorus and six trace elements in different topographical soils at Qianxian township of Yuanshi County in Hebei Province were analysed. The results showed that the contents of alkali hydrolysis N and olsen P in topsoil were lower than the average of those in other places of China.The six trace elements were also deficient, about 90% of the land were deficient of Zn and Mn,over 80% deficient of Mo and B,and about 60% deficient of Cu and Fe. The lower availabilities of soil untrients was closely correlated with the lower contents of organic matters.Landforms and soil types were also the factors influencing soil nutrient contents.
