FIELD: agriculture.
SUBSTANCE: method of obtaining fertilizer from bird droppings by mixing manure with mineral filler, mineral filler is used as mineral filler with density of no more than 0.2 g / cc in amount of 24-58% of volume of mixture total volume, and mixture is stirred at speed of 1300-1500 rpm for 3-5 minutes.
EFFECT: invention makes it possible to increase productivity of fertilizer manufacturing process by reducing mixing time of mixture, and also by eliminating need for prolonged exposure to resulting mixture, while improving quality of fertilizer obtained by increasing stability and uniformity in dispersion of resulting granules of this fertilizer.
