Essay

The dissertation is devoted to investigation of the influence of out-root additional fertilizing by trace elements on uptake and accumulation of 90Sr and 137Cs in fodder plants. It was established that foliar additional fertilizing of spring rape and yellow lupine by water solutions of trace elements Zn, and Mn at rate 200 and 300 g/ha increases yield and diminishes the accumulation of 137Сs in 1,5 - 2,0 times more and 90Sr in 1,2 - 1,4 times in vegetative parts and seeds.Application of trace elements in complexioned form greatly raises the radio block effect. The accumulation of 137Сs was decreased in 1,6-2,8 times and 90Sr was decreased in 1,4-1,6 times under the influence of zinc and manganese heterocomplexonate.
