FIELD: agriculture, fertilizers.
SUBSTANCE: method involves treatment of turf with hydrogen peroxide and aqueous ammonia. Treatment of turf is carried out at intensive vibration mechanical grinding for 0.5-3 h at temperature 25°C in the content of hydrogen peroxide 0.1-0.6 g/g and in the content of ammonia 0.25-0.5 g/g. Method allows enhancing the average content of humic and fulvic acids that improved quality of fertilizers obtained. Invention can be used in preparing nitrogen-containing organic fertilizers of prolonged effect based on turf.
EFFECT: improved preparing method.
