Technology for Production of Humic Preparations

In a number of countries, a tendency towards a decrease in the doses of applied mineral fertilizers is being monitored, and the role of their integrated use with agrotechnical methods aimed at maintaining natural soil fertility is increasing, including scientifically measures aimed at increasing the biodiversity of useful soil microflora. One of these techniques is the use of humic preparations. The purpose of the study is to develop a technology for the production of humic preparations using modern technologies in the field of mechanization and automation of technological processes, aimed at improving their consumer properties, as well as environmental safety. When developing the technology for industrial production of humic preparations, the following research methods were used: analytical, comparative, information-logical analysis of initial information, rated and constructive, expert assessments, a computer modeling method. The authors have developed an innovative technology for the production of humic preparations related to the combined production methods and aimed at increasing the efficiency of the technological process and the quality indicators of the resulting product. The developed technology made it possible to increase the efficiency of the extraction process of humic and fulvic acids by 1.5 times due to the combined effect on the raw material, as well as the differentiated introduction of alkali using a neural network. Through the use of a multistage purification system for the finished product, the proportion of insoluble inclusions in which was less than 1% with an average dimension of less than 10 microns.
