| Abstract [eng] |
The technology of dry NPK fertilizers has been analyzed, the composite NPK fertilizer sticks have been developed and technological recommendations for their production are presented in the Master's thesis. The classification of fertilizers, their properties, their effects and the need for plants are discussed in the literature review. Information on the impact of bacteria and microorganisms and the need for soil fertility is provided. The research section describes the materials used, the physical, chemical and instrumental analysis methods used in the work. The influence of various binding materials on complex NPKs has been determined and analyzed 6–24–33-5(CaO)-2(S) properties of fertilizer sticks (static strength, humidity, hygroscopicity). The principal technological scheme recommended for the production of compound NPK fertilizer sticks is in the engineering section. Workers' safety and health requirements are discussed. Work size – 54 pages. It consists of introduction, literature review, research part, engineering part of employee safety and health, conclusions, list of used literature. The explanatory note contains 11 tables, 29 figures. |
