Effect of exogenous selenium on soybean yield and its total N and P contents and on soil enzyme activities

Abstract

Abstract: Based on pot experiment with black soil,the effects of various concentrations and various valence of exogenous selenium on soybean yield and its Nand Pcontents and on soil enzyme activities were studied. The results showed that applying0.25μg·g^-1 soil and 0.5μg·g^-1 soil of both Se⁴⁺ and Se⁶⁺ could increase soybean yield and its Ncontent and promote soil urease activity, but decrease the Pcontent of soybean and soil phosphatase activity. When the concentration of Se⁶⁺ was 0.5μg·g^-1 soil, there was a significantly parabola relationship between the Ncontent of soybean and soil urease activity; and when the concentration of Se⁶⁺ was 0.25μg·g^-1 soil, there was a significantly parabola relationship between the Pcontent of soybean and soil phosphatase activity. There were no significant relationships between the Nand Pcontents of soybean and the activities of test soil enzymes when Se⁴⁺ was applied.
