Abstract:
The distribution character of soil nutrient and precision management of fertilizer in farmland in the piedmont of Taihang were studied.The experiment results show that the soil nutrient contents are laid in a range of one or two closed grades,so it is possible for soil nutrient to be managed in subarea.According to the classification criterion of soil nutrient,the soil fertility in this area is at a middle level.The content of soil available phosphorous(P)is closely related to winterwheat yield and fertilized phosphorous is the main factor affecting winter wheat yield.The nitrogen(N)fertilizer is the most important factor to the maize yield and second one is soil alkaline hydrolysis N or P fertilizer.
