Liquid organic nutrient for agricultural use which comprises calcium carbonate, of which the particles have an average size of less than 1 micron, at least one humic substance to provide nutrients N-P-K (1-0-19), hydroxiphyllosilicate of aluminum and magnesium (HPAM) with a high gelling capacity, and water which is used as a diluent. Method of producing the liquid organic nutrient for agricultural use, which comprises mixing at least one humic substance with water, adding calcium carbonate, grinding the mixture in a vertical pearl mill using a batch system for a sufficient time for the particles to have an average size of less than 1 micron, adjusting the percentage of solids to the initial value indicated in the nutrient formula, adding a quantity of hydroxiphyllosilicate of aluminum and magnesium, and recovering the particles of less than 1 micron from the product.
Liquid organic nutrient for agricultural use, characterized in that it comprises:
Nutrient according to the preceding claim, wherein the particle size distribution of the calcium carbonate is dp50=0.75 microns to 0.70 microns.
Nutrient according to the preceding claim, wherein the calcium carbonate had a purity of >99%.
Nutrient according to the preceding claim, wherein the humic substance is present in a quantity of 1 to 5%.
Method for producing the liquid organic nutrient for agricultural use according to the preceding claims wherein said method comprises:
Method according to the preceding claim, wherein steps i) and ii) are carried out using a grinder-stirrer system.
Method according to the preceding claim, wherein the humic substance is present in a quantity of 1% to 5%.
Method according to the preceding claim, wherein the sufficient quantity of the liquid organic nutrient is from 10 L of liquid organic nutrient per ha.
Method according to the preceding claim, wherein the sufficient quantity of the liquid organic nutrient is from 5 L of liquid organic nutrient per ha.
Use of humic substances as a dispersing agent in processes for reducing the particle size of substance of interest.
