FIELD: agriculture.
SUBSTANCE: invention relates to the agriculture. Fertilizer contains weight fraction of coke-chemical ammonium sulphate in powder form, weight fraction of dolomite (limestone) flour, weight fraction of phosphorite flour, weight fraction of powdered potassium chloride, wherein it additionally contains weight fractions of salt forms of microelements, such as manganese sulphate, iron sulphate, copper sulphate, zinc sulphate and boric acid. All components are taken at a certain ratio.
EFFECT: invention enables to develop a complex universal granular NPK fertilizer composition with a set of trace elements (Mn 0,06 %, B 0,02 %, Zn 0,02 %, Fe 0,1 %, Cu 0,01 %), characterized by pronounced agrochemical efficiency and soil-protective properties, promoting fertility restoration of soil and increased crop capacity.
