- Abstract
[Objective] In order to reveal the relationship between total amount of four main soil trace elements, soil organic carbon and pH, in Xiao-guan Dong minority township Xuanen county Enshi city, the effect of soil organic carbon and pH on four trace elements in soil was studied. [Method] Using the soil in this area as the research object and taking soil samples in per square kilometer grid, 2127 samples were selected to analyze four kinds of soil trace elements in total quantity,includes iron, manganese, zinc, copper, and organic carbon also pH, the relationship between soil organic carbon and pH in four soil trace elements was analyzed. [Result]The correlation between soil trace elements Fe, Mn, Cu and organic carbon significantly (P < 0. 01) decreased with the increase of organic carbon. The correlation between trace elements Fe, Mn, Zn, Cu and the pH value of the soil were significant (P < 0. 01), and increased with the increase of soil pH. [Conclusion]The accumulation of organic carbon in the soil organic carbon in the county of enshi xuanen county has led to a decrease in the amount of iron, manganese and copper in the soil, but has no significant effect on zinc elements. The increase of soil acidity in the results of the analysis results in an increase in the amount of trace elements iron, manganese, zinc and copper in the soil.
