FIELD: mixed fertilizers.
SUBSTANCE: object of invention is preparation of fertilizers from solid combustible fossils and, in particular, consists in mixing ground coal containing at least 50% humin acids with alkali additives in rotary mixer. First, total batch of coal is loaded and then alkali is added at a velocity maintaining temperature of reaction mixture in the range of 70-80оС, alkali-to-coal weight ratio being (0.125-0.150):1.
EFFECT: reduced expenses on providing humin acids.
