ИССЛЕДОВАНИЯ ПО ПОЛУЧЕНИЮ ХЕЛАТНОГО ПОЛИМЕРСОДЕРЖАЩЕГО МИКРОУДОБРЕНИЯ НА ОСНОВЕ ТЕХНОГЕННЫХ ОТХОДОВ.

Background. A method of obtaining microfertilizer, in which the fertilizer is obtained by the joint processing of humates of allkali metals and salts of trace elements in the solid phase, followed by mechanochemical activation of the mixture in the presence of an oxidizing agent (potassium permanganate) and an alkaline agent. However, this method is considered economically impractical from the point of view of the complexity of the technological design and, as a consequence, the need to purchase expensive equipment [1]. The objective of this work is to develop a method for producing a chelated polymer-containing microfertilizers, which reduces the cost of the process, improves the quality of the finished product and partially solves the issue of recycling technogenic waste. Purpose. Studying the process of obtaining chelated polymer-containing microfertilizers based on technogenic waste. Methodology. The chemical composition of raw materials and the yield of humic acid determined using SEM and IR spectrum. Originality. A method has been developed for the preparation of chelated polymer-containing microfertilizers based on phosphorus sludge - waste phosphorus production and bird droppings, and humic acid is used as a solvent using SAS «OGSPlast» surfactant as a chelating agent with trace elements. Finlings. It was established that mainly in the presence of chelated polymer-containing microfertilizers is formed in the form of an amorphous structure with a partial appearance of crystallization structures, it is also determined that microfertilizers obtained are characterized by a high content of humic substances that are involved in the structure of the soil, the accumulation of nutrients and trace elements in plants accessible to plants form, contribute to the regulation of geochemical metal flows in water and soil ecosystems.
