THE ROLE OF CHELATE COORDINATION COMPOUNDS OF BIOGENIC METALS IN THE VITAL ACTIVITY OF PLANTS

The review article discusses the main issues of creating and using modern chelated microfertilizers based on trace elements in agricultural production. Issues of the role of microelements in the vital activity of living organisms and methods of overcoming the lack of micro­elements in plants are highlighted. An overview of coordination compounds of 3d-metals (Fe, Mn, Zn, Cu, Co, Ni, Mo) with different classes of complexons, features of their structure and properties is presented. It contains relevant material on the use of microelement complexes for the creation of modern chelated fertilizers. Attention is paid to the use of trace elements complexonates in areas contaminated with radionuclides (137Сs, 90Sr).
