FIELD: agriculture.
SUBSTANCE: organic and mineral fertilizer of prolonged action is obtained from diatomite of a given fractional composition with a bulk density of 0.8 kg/dm3, a granule size of 0.05–0.1 cm, a porosity of 80–85%, a silicon content of 76–85% and sapropel in a ratio of 50/50. The mixture is thermally stabilized by heating to a temperature of 65°C and achieving humidity in the range from 10% to 12%.
EFFECT: fertilizer allows to increase the stress resistance of plants and maintain a stable level of moisture, improve soil aeration, retain moisture during the dry season, increase the biological activity of the fertilizer.
