Abstract

This article provides information on the development of a technology for the production of polymer-containing microfertilizers based on humic acid obtained by decomposing coal waste from the Lenger deposit. Also describes the composition of coal waste and humic acid determined with using SEM and IR spectrum. For benefication with microelements, a solution of ammophos, boric acid, copper sulfate, potassium sulfate and ammonium molybdenum acidic is added to the mixture obtained, as a chelating agent SAS «GS-1». The got polymer-containing microfertilizers are characterized by a high content of humic substances, that participate in the structure formation of the soil, accumulation of nourishing elements and microelements in an accessible for plants form, contribute to the regulation of metal content in aquatic and soil ecosystems.
