FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, namely to the production of a complex fertilizer containing carbon dioxide. The method provides for obtaining a complex fertilizer containing carbonic acid and a component based on bulk material, including nutritional ingredients. As the specified component, a natural mineral is used - serpentinite, wet milled in a carbonic acid medium. Before the specified grinding, the serpentinite is first subjected to crushing to achieve a size acceptable for equipment used for wet grinding, then it is poured with carbonic acid and kept for at least 7 hours. In this case, wet grinding is carried out at the initial mass ratio of solid and liquid phases in the processed material S:L from 1.2:1 to 1.4:1 and is carried out until the resulting product reaches a pasty consistency with a particle size of not more than 0.02 mm.
EFFECT: ensuring the possibility of obtaining fertilizer as a single material applicable by directly introducing it into the soil during plowing or pre-sowing preparation while maintaining the properties due to the presence of carbon dioxide, as well as ensuring the gradual release of the latter.
