STUDY OF PHYSICOCHEMICAL PROPERTIES OF 16;16;16;5 BRAND NPK FERTILIZER IN LABORATORY CONDITIONS
Keywords:
NPK, ammaphos, urea, KCl, NH4SO4, nitrogen, phosphorus, potassium, laboratory, solubility.Abstract
In this article, the physicochemical properties of the 16;16;16;5 brand NPK fertilizer were studied, ammaphos, urea, potassium chloride and ammonium sulfate were ground and mixed in laboratory conditions, and granular fertilizers of the required size were obtained. The appearance, internal structure and quality of the NPK granules of this brand obtained in laboratory conditions were evaluated. In particular, the surface structure, particle shape and degree of intergranular adhesion (agglomeration) of the NPK granules were visually and microscopically analyzed using a Euromex Microscopen B. V. microscope.
