[The agronomical and radiological estimation of application of different kinds and dozes of organic fertilizers at improvement waterless valley types meadows contamination 137Cs and 90Sr].
On the basis of agronomical, economic and radiological estimations of results of long-term researches with organic fertilizers (peat, sapropel, manure, mixes manure and peat) it is established, that is effective at improvement of the waterless meadows on sod-podsolic sandy soils contaminated by radionuclides to bring in 40-60 t/ha mixes manure and peat or covering the manure, on a background liming and mineral fertilizers (level of profitability--4.8-8.7%), providing reception of the maximal increase of a crop (6.0-7.5 t/ha of hay) and decrease to 10 times of size of transfer factors of 137Cs and to 3.0 times 90Sr in a crop of long-term cereal herbs (size of the prevented collective doze, deltaD - 0.0060-0.0065 man-Sv per one year; cost of the prevented collective doze, deltaepsilon--11500-13000 $ on 1 man-Sv annually. The application of 40 and 60 t/ga of peat and sapropel in the pure state on a background liming and mineral fertilizers is not expedient, as cost of additional production does not cover total expenses for their entering (level of profitability--20-32.0%), the and cost of the prevented collective doze exceeds 20000 $ US per 1 man-Sv annually.
