One of the most important problems of agriculture under conditions of the soil contamination with radioactive elements is the maximum possible decrease in the supply of these substances to crop production and prevention of their accumulation in the organisms of farm animals. In connection with this, now we have a problem of introducing new technologies and techniques not only in the agrochemical survey of lands but also in the agro-industrial complex as a whole. This article presents experimental data on the concentration of radionuclides 137Cs, 90Sr, 232Th, 226Ra, and 40K in the soils of agricultural enterprise «Druzhba» in the Gorky District of the Omsk Region. The survey was conducted in 2016 on the basis of the Center for Agrochemical Service «Omskiy». The content of 137Cs and 90Sr was shown not to exceed background indices, whereas the use of potassium fertilizers and the composition of soil-forming rocks gives rise in the increase in the content of such radionuclides as 40K, 232Th and 226Ra.
