Monoammonium Phosphate fertilizer has been an important granular fertilizer for many years. Mono-ammonium Phosphate fertilizer is water-soluble and dissolves rapidly in adequately moist soil. Upon dissolution, the two basic components of the fertilizer separate again to release ammonium (NH₄⁺) and phosphate (H₂PO₄⁻), both of which are necessary for plants to rely on for healthy, sustained growth. The pH of the solution surrounding the granule is moderately acidic, making MAP an especially desirable fertilizer in neutral- and high-pH soils.

  • Instructions on the package should be followed to determine the rate in pounds per square footage that you will need. This will vary depending on the type of grass you are fertilizing, whether it is being used for pre-planting or maintenance and how much actual nitrogen you need to add to your lawn.
  • Set the lawn spreader according to the instructions on the package to get the appropriate coverage.
  • Water the lawn with 6 inches of water immediately after fertilizing. Fast-release fertilizers will burn the grass if not washed off right away.
