INNOVATIVE TECHNOLOGY OF PRODUCTION OF ORGANOMINERAL FERTILIZERS FROM VARIOUS TYPES OF ORGANIC RAW MATERIALS
The use of organic-mineral (humic) fertilizers in agriculture contributes to the following positive results: the resistance of crops to negative weather and climate conditions, in particular, drought, and soil structure deterioration. Moreover, the effectiveness of the use of organic fertilizers largely depends on their quality, which, in turn, is determined by the production technology. This article discusses an innovative technology for the production of organic fertilizers from various types of organic raw materials. According to the proposed technology, the raw materials undergo preliminary preparation (grinding, sieving, hydration and separation of insoluble inclusions), after which it is subjected to alkaline extraction and cavitation dispersion until the active formation of humic and fulvic acid salts ceases. Next, the suspension of finished organic fertilizers passes through a multi-stage purification system, and then, to obtain complex fertilizers, micronutrients are differentially introduced into the organic fertilizer stream.
