CATION-ANION STRUCTURE OF LYSIMETER SOLUTIONS FROM ARABLE SOILS OF BELARUS (according to 1981-2012)

Abstract

The data of long-term lysimeter researches on cation-anion structure of sod-podzolic soils different texture are cited. The sum of ions (аnions and cations) in lysimeter solutions during researches (1981-2012) changed from 5,8 (sandy) up to 9,9 mg-equivalent/l (coherent sandy soil spread with moraine loams). Change of ionic structure and cation and anion correlation in a soil solution are influenced with entering lime means, organic and mineral fertilizers. At the raised dozes of entering both mineral, and organic fertilizers, the cation and anion content in a soil solution increases. At the moderate dozes of fertilizers attitudes (HCO3-/Са2 +, SO42-/Са2+и Cl-/Са2 +) decrease, that testifies to pollution decrease of ground and superficial waters by hydrocarbonates, sulfates and chlorides.
