Gromag - Quick Release Fertilizer

Since the advent of acid phosphate and more concentrated phosphatic fertilizers such as super phosphates, the growth in area of salt and acid affected agricultural land on a world-wide basis has been extremely significant.

The Calix technology takes advantage of the fact that the addition of partially calcined dolomite to any type of crop or pasture affected by acid or salt obtained from the application of phosphate fertilizers will neutralise the acid and salt content of the soil.

Further, the fertilizing dolomitic material when introduced to the aqueous system of the soil supplies magnesium as a plant food in three concentrated and available forms of magnesium phosphate, carbonate and bicarbonate.

This is because the magnesium hydroxide and magnesia oxide are inactive and insoluble in dry conditions and are readily and immediately transformed into soluble magnesium carbon through reaction with the carbon dioxide of the soil.

The calcined dolomitic materials should be spread dry on the surface of the pasture or soil at any rate capable of bringing about the chemical reaction of rapid released fertilisers as described here.

Because of the preferential reaction of the magnesium with the phosphoric acid the calcium carbonate contained within the dolomitic material shall remain in its original condition as a concentrate and available form of calcium which will be readily and rapidly assimilated as a food by the plant.
