Movement of Elements in a Rock-Soil System and the Effects of a Geological Environment on Agriculture in the Ningguo Region, Anhui Province

How the movement of elements in a rock-soil system affects agriculture in a given geological environment is an entirely new study subject in petrology and geochemistry. This paper generalizes the fundamental features of the geochemical distribution of elements in various soil and rock types in the Ningguo region, Anhui Province, by means of the measurement of trace element abundance in bedrock-soil sections. The results show the regular movement patterns of elements in a rock-soil system in this region. Six trace elements Fe, Mn, Cu, Mo, Zn and B, indispensable to plant growth, are abundant in soil. It shows that, in Nanhuan system-Cambrian system, Fe, Mn and Cu are abundant in soil. This clearly suggests that the movement of elements in a rock-soil system significantly affects the growth environment of well-known agricultural, and forest products in Tianmu Mountains of Ningguo region. Walnuts, the leading product in Tianmu Mountains, are suited to the soil in the area of the Nantuo, Lantian, Yangliugang, Huayansi and Xiyangshan formations.
