On a basic of an economical and radiological estimation of outcomes of perennial researches with organic fertilizers (peat, sapropel, manure) is established that is economically justified (yield rate - 5,3%) at improvement of the dry meadows, contaminated by radionuclides, on sod-podzolic sandy soils to apply manure in a dose 40 t/ha a background calcareous and mineral fertilizers ensuring to obtain the maximum yield increase (6,0-7,5 t/ha of hay) and a decrease to 10 times of value of transfer factors 137Cs and in 3,0 times 90Sr in yields of perennial grases at the highest value of a prevented collective dose - 0,0045 man-Sv per one year
