Abstract
The concentration and distribution of metal (Mg, K, Ca and Na) elements in agricultural and non-agricultural soils were investigated in upstream of the Pearl River, China. The result showed that total Mg, K, Ca and Na concentrations in agricultural soils were higher 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 Mg, K, Ca and Na 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 Mg, K and Na were lower in both agricultural and non-agricultural soils in the study area, while Ca was relatively higher, which were possibly due to Karsts geographic environment in the study area.
