Oleksandr D. Scientific basis for the formation of agroecosystems in the radioactively contaminated territories

The Dissertation devoted to the scientific basis for the formation of agroecosystems in the radioactive contaminated territories, key approaches to optimize the ussng of countermeasures, their timing and significance of the peculiarities remote period of the radiological situation. Proved that the most important critical factors that determine the intensity of 137Cs migration in primary food chain is a set of indicators of soil fertility. The chemical reclamation of contaminated soils and optimization of potassium nutrition of plants remain one of the main anti-radiation measures. It's shown, that the efficiency of potassium fertilizers application based on reduction in the content of available forms of potassium in the soil to the content of 137Cs in it. Investigated the ecological and radiological aspects of crop rotation in the radioactive contaminated territories. They are based on the individual characteristics of agricultural plants to accumulate radionuclides from the soil. A science-based areas of specialization of economic activity for guaranteed to produce radiologically safe agricultural products. It's proved priority for agricultural production, which is not used directly in food needs. Substantiated the scientific approaches to improve monitoring and control of radionuclides content in agricultural products in the remote period after the Chernobyl disaster. The directions of optimization, priorities and conditions for the effective application of countermeasures to overcome the consequences of the Chernobyl disaster in agricultural contaminated regions.
