Monoammonium phosphate is ideal for use in the initial growth phase of all crops, immediately before and after seeding and planting/transplanting. Highly efficient source of phosphorus as phosphate (H₂PO₄-)  which promotes rapid absorption by the plant, MAP provides an acidifying effect on the soil solution favouring solubility of phosphorus and micronutrients, freely soluble and quickly dissolving, Product of high purity, no residue or contaminants.
