Concentration and Distribution of Fe, Al, Mn and Cr in Soils

Article Preview

Abstract:

The concentration and distribution of metal (Fe, Al, Mn and Cr) elements in agricultural and non-agricultural soils were investigated in upstream of the Pearl River, China. The result showed that total Fe, Al and Cr concentrations in agricultural soils were higher than those in non-agricultural soils, while total Mn concentrations in agricultural soils were lower than those in non-agricultural soils, indicating that agricultural input, such as water irrigation, fertilizer and pesticide application, may have led to the accumulation of Fe, Al and Cr in agricultural soils. Total concentrations of the metal elements in agricultural and non-agricultural soils were compared with the background values of Yunnan soil, the result showed Fe, Al, Mn and Cr were lower in both agricultural and non-agricultural soils in the study area.
