Role of sulphate in affecting soil availability of exogenous selenate (SeO42-) under different statuses of soil microbial activity

Popis výsledku v původním jazyce

We investigated sulphate application, different statuses of soil microbial activity and their joint effects as variables associated with changes in potentially plant-available selenium (Seppa) and soil Se fractionation during the course of an incubation study. The behaviour of added selenate in two agricultural soils was elucidated by means of single extraction (50 mmol/L NH4H2PO4), sequential extraction procedure (SEP) and chemical speciation analysis. The decrease in phosphate-extractable Se, a consequence of soil aging, was inhibited by sulphate (by 34 and 29% in Chernozem and Cambisol, respectively) and by gamma-irradiation (by 46 and 20% in Chernozem and Cambisol, respectively) after 72 days of incubation as compared to the control treatments. Glucose amendment dramatically decreased Seppa only in the Chernozem. After 1 year, the initial soil treatment with respect to inhibited or stimulated microbially-mediated processes substantially controlled the distribution pattern of exogenous Se.
