Liquid organic nutrient for agricultural use and production method thereof

An organic nutrient for agricultural use, consisting of:

• i) calcium carbonate consisting of particles having an average size of less than 1 micron and a relative neutralizing power of 100%;
• ii) at least one humic substance capable of releasing nitrogen, phosphorous and potassium having a N-P-K value of 1-0-19;
• iii) attapulgite (hydroxiphyllosilicate of aluminum and magnesium (HPAM)) with a gelling capacity and a relative neutralizing power of 30%;
• iv) water used as a diluent;
• v) wherein the particle size distribution of the calcium carbonate is dp50=0.75 microns to 0.70 microns, the calcium carbonate has a purity of >99% and the calcium carbonate is present in a quantity of no less than 65% of the liquid organic nutrient;
• vi) wherein the attapulgite is in a quantity of 0.1% to 0.5% of the liquid organic nutrient;
• vii) wherein the humic substance has a purity of over 90% and is present in a quantity of approximately 1% to 5% of the liquid organic nutrient;
• and
• viii) wherein the organic nutrient is a liquid.
