INFLUENCE OF AGROCHEMICAL PROPERTIES OF SOD-PODZOLIC SANDY SOIL ON137Cs AND90Sr ACCUMULATION BY GREEN MASS OF PEAS

Abstract

Correlation analysis showed enough close negative relationship (r) between the pH, the content of mobile forms of phosphorus and potassium in sod-podzolic loamy sand soils and the transfer coefficients of¹³⁷Cs and⁹⁰Sr in the green mass of peas. The content of mobile potassium, at which there is a minimum accumulation of¹³⁷Cs by green mass of peas is in the range of 350-379 mg/kg, humus - 2.3-2.5 % and⁹⁰Sr at pH of 5.7-6.3. The content of mobile phosphorus, at which there is a minimum accumulation of⁹⁰Sr with green mass of peas is in the range of 210-240 mg/kg, the exchangeable CaO of 950-1050 mg/kg.
