EXCHANGEABLE CALCIUM OF SOIL AND90Sr ACCUMULATION BY CROPS
Abstract
In the field experiments conducted on sod-podzolic loamy sand soil (Podzoluvisol) сlose negative correlations have been found between exchange calcium contents in the soil and90Sr accumulation by plants. The efficiency of soil saturation by calcium in discrimination of90Sr is much higher on soils with low Ca status. The minimum of bioavailability of90Sr was observed at the content of exchange calcium for grain crops at 1300-1400 ppm of soil, rapeseed - 1195, corn - 1236, timothy grass - 980, clover - 1229, alfalfa - 1502 and potato - 1260 ppm of soil.
