Abstract: AQEOUS SUSPENSION FERTILIZERS RESISTANT TO SEFIMENTATION AND FORMATION OF LARGE CRYSTALS AND SOLID AGGREGATES ARE FORMULATED TO COMPRISE A WATER-SOLUBLE POLYPHOSPHATE AND A WATER-SOLUBLE MAGNESIUM COMPOUND. THE RATIO OF THE WEIGHT OF THE POLYPHOSPHATE (EXPRESSED AS P2O5) THE WEIGHT OF THE MAGNESIUM COMPOUND (EXPRESSED AS MGO) IS BETWEEN ABOUT 0.2 AND ABOUT 2, AND THE SUM OF THE WEIGHT OF THE POLYPHOSPHATE (EXPRESSED AS P2O5) AND THE WEIGHT OF THE MAGNESIUM COMPOUND (EXPRESSED AS MGO) CONSTITUTES BETWEEN ABOUT 0.5% AND ABOUT 12% OF THE TOTAL WEIGHT OF THE FERTILIZER COMPOSITION.
