Radiological condition of lands of agricultural purpose and production of plant growing of the forest-steppe of Omsk region

On the basis of radiological monitoring in the forest-steppe zone of Omsk region the studies were made to determine the changes in the content of toxicants in the plow horizon of soil benchmark sites of the experimental fields. Also the agricultural production grown up on these soils of benchmark sites of experimental fields was studied and ana-lyzed. The material of 9 years of supervision was the basis for the researches. They were carried out on 2 benchmark sites of experimental fields: in JV “Lezhansky” of Gorky area and SPK “Pushkin” of Omsk territory of Omsk region. It was revealed that the content of dangerous artificial radionuclides in arable horizon of soils of benchmark sites of exper-imental fields was steady and did not exceed aver-age Russian indicators. Considering it, and also that the studied agricultural production was not pol-luted, it was revealed that the radiological situation on the benchmark sites of experimental fields was favorable. Despite a favorable situation concerning radionuclides on the benchmark sites of experi-mental fields and in the forest-steppe zone of Omsk region, the need of radiological monitoring was ob-vious as for the acceptance of timely preventive measures it was important to have the system of early detection of changes in natural ecosystems and agricultural landscapes.
