METHOD OF PRODUCTION OF ORGANOMINERAL FERTILISER Russian patent published in 2015 - IPC C05F11/02 

FIELD: agriculture.

SUBSTANCE: method of production of organomineral fertiliser comprises treatment of coal by chemical action, and mixing it with nutritional ingredients, at that the sooty coal is taken with the fraction of 1.1-7.8 mm and is mixed at ambient temperature with the nutritional ingredients in the form of the montmorillonite and phosphate clay with the fraction of 1.1-7.8 mm each at a weight ratio of 2:0.5:1, the 12-15% solution of ammonium sulphate is added into the mixture, and then the mixture is treated with cavitation dispersing at a temperature of 10-55°C for 10-20 minutes, the resulting suspension is placed in a closed vessel for 14-30 days to complete chemical interaction.

EFFECT: invention enables to reduce the cost 2-3 times due to the use of natural ingredients, to increase the yield of grain crops.
