Justification of production indicators of organic fertilizer based on sapropel

Abstract

Abstract The problem facing agricultural scientists is the search for effective ways to develop sapropel for fertilization to increase crop production by increasing soil fertility. One of the most important reserves of organic raw materials are the reserves of lake sapropels. It has been established that sapropel deposits, depending on the depth, have different values of agrochemical and physical properties. Having processed the empirical values of the sapropel characteristics in accordance with the requirements of the technological parameters, we obtained the optimal depths of the layer for industrial development. Its efficiency can be increased when applied together with lower doses of mineral fertilizers. To improve the technological process for the production of sapropel fertilizers, it is necessary to take into account that sapropel should be extracted from a scientifically substantiated layer of the deposit and in its natural state sapropel is not a full-fledged fertilizer; its effectiveness can be increased because of application together with mineral fertilizers. Mixing is one of the most important operations in fertilizer production technology and for this purpose; it is advisable to use a drum mixer.
