Yield and Cs137 and Sr90 accumulation by crops depending on rates of potassium fertilizer

In field experiments was established that Cs137 and Sr90 content in crops are reduces at the increasing of extractable potassium content in soils up to 240-260 mg/kg of soils. The effectiveness of application of potassium fertilizers depends on potassium soil status, soil acidity and level of manure application. The high rate of potassium fertilizers taking account of soil fertility allows to increase the crop yield i 1,5-4,8 times with reducing of Cs137 and Sr90 accumulation in 1,3-4,0 times tj the control treatment without fertilizers
