Purpose of research is the study of ecologic and economic efficiency of specific antiradionuclides countermeasures in different soil types and in different landscape-ecological conditions. Research methods and equipment are caesium-137 in soil determined by spectrometry method on the analyzer of impulses АІ-1024-95 with the stintillation detector БДЕГ- 2-23; in plants - on the betta-radiometer РУБ-014ПС. Measuring of gamma-background was conducted by a dosimeter РМ1701М. Strontium-90 defined by radio-chemistry method on the device УМФ-2000 and spectrometer "Gamma-plus". Agrochemical researches were spent according to the techniques actual in agroservice. Soil pollution density in critical territories (pastures for the private milch herd of cows) and vegetable mass pollution level has been defined. Entwinement between the level pollution of vegetable mass and ground cover and influence agrochemical parameters on migration of radionuclides of soil are founded. It allows to develop the forecast of pollution of a pasturable forage and to give recommendations about use of a pasture or its replacement. Information about survey of critical pastures near 22 settlements with total area of 3098 hectares has summarised. The level of pollution by cesium of pastures forage definitely in 292 samples. Average level of pollution is 128 Bq/kg and it limits 20-1266 Bq/kg. In the 29 samples the permissible level of pollution was exceeded. Pollution of green mass by strontium is in limits 1-389 Bq/kg, having average value of 30 Bq/kg. Ecologic efficiency of countermeasures has been implemented. Liming reduces the pollution of crop production in 1.6-2.4 times and рНсол increase in 0.7-1.1. Potassium fertilization increases efficiency of liming. Generalization of study results revealed that the ecological most effective interventions are a one-time deep plowing (pollution of products reduced in 7-10 times), grassing arable land (2-8 times), surface improvement of meadows (1.5-2.5 times). Agrochemical methods reduce pollution: liming (1.5-2.5 times), fertilization (1.3-2.4 times). Zeolite introduction reduces the acidity on 0,4-0,6 units and reduces pollution phytomass on 13-32%. The high economic efficiency of countermeasures was defined. Liming increases the yield on 12-94%, fertilization - 33-165%, compatible action of these methods - 33-165%. The use of zeolite resulted in growth of yield on 36-187%. The profitability of these activities varied from 43 to 167%.
