Recultivation of soils contaminated with radionuclides by phytomelioration

Abstract

The use of aqueous solutions of ammonium nitrate and microorganisms in the proposed method will intensify the transition of radionuclides into soluble forms for assimilation by the root system of plants, obtaining maximum biomass of plants accumulating radionuclides, and significantly reducing the growing season. The process of obtaining biomass using the above technology makes it possible to repeat this method of purification many times, including within one seasonal period, until the content of radionuclides in the soil reaches acceptable values, after which the soil becomes suitable for agricultural use. The purpose of the study. Consider the transition of radionuclides into soluble forms for assimilation by the root system of plants. Material and Methods. To substantiate the possible directions of soil reclamation, we propose a conceptual model of radionuclide transport in the agrocenosis, on the basis of which a functional scheme for recultivation of soils contaminated with radionuclides has been developed. The collected biomass and the root system of plants must be disposed of. Due to the fact that large volumes of mass are subject to disposal, it is subjected to heat treatment - drying.
