Summary

Continuous, systematic use of fertilizers affects the stability of the fixing of radioactive products of division and CO60 in the soil, and especially affects the accumulation of radioisotopes in the plant yield. Application of mineral fertilizers greatly affects the intake of radioisotopes from the soils to the plants. When manure is systematically used with mineral fertilizers on calcareous soils, there is an increase in the stability of the fixing of Sr90, Cs137, Ce144 and Co60; this is accompanied by a significant reduction in the accumulation of these radioisotopes in the oat yield. Intake of Co60 and its accumulation in the yield is considerably increased when nitrogenous fertilizers and N in combinations are introduced into the soil. When nitrogenous fertilizers are used over a long period there is a reduction in the stability of fixing Co by the soil.
