INFLUENCE OF AGROCHEMICAL PROPERTIES OF SOD-PODZOLIC SANDY SOIL ON the accumulation137Cs BY GREEN MASS OF CORN
Abstract
The сlose negative nonlinear correlations have been found between indexes of soil fertility and137Cs accumulation by corn in field experiments conducted on sod-podzolic sandy soils. The minimum bioavailability of137Cs for corn cultivated for green mass was observed at the organic matter content of 3.1 (2.8-3.5) %, mobile potassium - 436 (385-462) ppm, exchange magnesium - 244 (197-302) ppm and pH(KCl) - 6.3 (6.1-6.5). The effectiveness of soil saturation with organic matter, potassium and magnesium in137Cs discrimination is much higher on soils with low supply of these nutrients for plants.
