FIELD: organic chemistry; production of fertilizers; agriculture. SUBSTANCE: main precursor components, namely, manure or droppings of poultry and finely ground chalk are mixed together in weight ratio 1.0:(0.6-1.5) and granulated by pelletizing with additive or without them in drum-type granulator, followed by sizing pellets on roller screen. Resulting granules are dried at temperature 110-120 C. Granules are strong and may have any predetermined chemical composition. EFFECT: higher efficiency. 2 cl, 1 tbl
