Research results on the chemical elements' absorption from the soil of the agricultural crops in organic farming technologies

Abstract

Annotation Purpose. Research and children of cultivation of environmentally friendly crop products in various soil and chemical conditions of Ukraine according to organic farming technologies. Methods. Monographic, analytic, experimental-field. Results. As a result of the conducted experiments on obtaining environmentally friendly crop products in different soil and climatic conditions of Ukraine using organic farming technologies, it was established that to obtain environmentally friendly crop products in the presence of harmful substances in the soils, the concentration of which exceeds the maximum permissible concentration (MPC) Impossible. Conclusions. According to the results of the conducted research on the cultivation of environmentally safe crop products in different soil and climatic conditions of the Southern Steppe and Forest-Steppe of Ukraine on organic farming technologies and organic farming technologies BTU-center, ENZIM, center of effective technologies and Danube technologies were established: - in the presence of the content of chemical elements in various types of soil with exceeding the maximum permissible concentrations, it is impossible to grow environmentally friendly crop products; - for the cultivation of environmentally friendly crop products, it is necessary to substantiate the MPC in the soil for 78 chemical elements; - need to be developed a universal controlled program of the intra-soil agrochemical process, taking into account all chemical elements from hydrogen to uranium, their compounds, and on the basis of such a program to develop a combined laser analyzer to determine the gross content of chemical elements in the soil in the mode of movement of the unit and at the same time to bring into the soil necessary and chemical and elements for creating favorable conditions for the growth and development of crops in the soil. This will make it possible to reproduce soil fertility, grow environmentally friendly agricultural products, reduce the burden on the environment, regardless of climate change.
