Abstract. Under coverage, it is advisable to use liquid complex fertilizers with chelated microelements. They have a positive effect on the growth and productivity of plants under adverse weather conditions. For many years, Kurchatov Institute has been developing complexones and complexonates obtained on their basis. The paper presents a table of liquid complex fertilizers (LCF) with chelated microelements on various matrices. Complex LCF Helaton EXTRA on oxyethylidene diphosphonic (OEDP) and ethylenediaminetetraacetic (EDTA) acids contained six metals (zinc, iron, copper, manganese, molybdenum, and cobalt), as well as inorganic boron. Kurchatov Institute developed a technology for producing a liquid concentrate of microelements, which in turn allows producing chelated fertilizers with two, three, or more microelements. It is a solution of dark green colour, stable at temperatures varying from -10 C to +50 C with a neutral reaction of the medium.
Keywords: microelements; complexones; complexonates; chelated fertilizers; production technology; liquid complex fertilizer.
