LABILE ORGANIC MATTER AS A FACTOR MOBILIZATION- IMMOBILIZATION OF TRACE ELEMENTS IN SOILS

Abstract

The article presents data on changes in trace element composition in chernozems soils of Left-bank Forest-steppe zone of Ukraine and labile organic matter under the influence of the soil plowing, long-term using of fertilizers and crop rotations. Determined that treatment of chernozem soil bring to a significant reduction of the labile organic matter content, in composition sharply occurs increases mass fraction trace element. Prolonged use of fertilizers contributes to the enrichment of labile soil organic matter with copper and iron, while when contributing manure, on the contrary, contained relatively less trace elements. Ability of the soil to the mobilization / immobilization of trace elements from organic matter by microorganisms could assessed by the indicator, which are, defined similarly nitrification capacity.
