Monoammonium Phosphate (MAP) is a widely used, water-soluble fertilizer valued for its high content of phosphorus (P) and nitrogen (N)—two essential nutrients for plant development. Chemically represented as NH₄H₂PO₄ and registered under CAS No. 7722-76-1, MAP contains approximately 11% nitrogen and 52% phosphorus (as P₂O₅), making it one of the most phosphorus-rich solid fertilizers available on the market. It appears as a white or off-white crystalline powder or granules and is known for its excellent solubility and quick nutrient release in soil.

MAP is produced through a straightforward chemical reaction between ammonia (NH₃) and phosphoric acid (H₃PO₄)—two staple raw materials in the fertilizer industry. The result is a stable compound that is low in moisture, free-flowing, and suitable for blending with other fertilizers or for direct application. Its low pH in solution (around 4.5) also improves nutrient uptake in alkaline soils and reduces ammonia loss, enhancing fertilizer efficiency.

In agriculture, Monoammonium Phosphate is favored for starter fertilizer formulations, especially for crops like cereals, oilseeds, vegetables, and fruits. It promotes strong root development in early plant stages, making it ideal for placement near the seed during planting. MAP is also used in fertigation and foliar spray systems due to its high purity and compatibility with other soluble fertilizers.

With its high nutrient concentration, excellent solubility, and reliable performance across soil types, MAP is a cost-effective and agronomically efficient solution for modern farming. It is typically available in 25 kg and 50 kg moisture-proof bags, with custom packaging available for bulk agricultural distributors.

Hydrofluoric Acid

Iron (II) sulfate is sold as ferrous sulfate, a soil amendment^[23] for lowering the pH of a high alkaline soil so that plants can access the soil's nutrients.^[24]

In horticulture it is used for treating iron chlorosis.^[25] Although not as rapid-acting as ferric EDTA, its effects are longer-lasting. It can be mixed with compost and dug into the soil to create a store which can last for years.^[26] It is also used as a lawn conditioner,^[26] and moss killer.
