Abstract

A new type of micronutrient liquid fertilizers was obtained by treating the calcium nitrate porridge obtained on the basis of research with urea (ammonium nitrate, KAS) and micronutrient (Cu Zn Co) salts in the amount necessary for plant growth. The chemical composition, product properties and rheological properties of liquid fertilizers containing microelements were studied, and a laboratory device for the production of liquid fertilizers was created. As a result of preliminary investigations, it was found that copper, zinc, molybdenum, manganese, calcium, magnesium are the most scarce trace elements in the soils of our republic. In order to apply microelements to the soil as fertilizers, the research was carried out in order to find their various sources, to study various industrial residues, to solve the problems of testing, processing of local raw materials and industrial waste containing trace elements a rational technology for obtaining new types of simple and complex liquid, granular and suspended fertilizers was developed, and its agrochemical properties and the amount of microelements in the plant composition and its effect on the absorption of nutrients (NRK), cotton yield and quality parameters of fiber were determined when used in typical gray soil conditions.
