Crop Nutrition

MAP

purpose

Monoammonium Phosphate (MAP) is a highly effective source of phosphorus and nitrogen for crops, providing balanced nutrition for strong root establishment, vigorous growth, and higher yields. MAP is water-soluble and quickly delivers essential nutrients, making it a popular choice for both broadacre and specialty crops. Its acidic reaction helps improve nutrient uptake, especially in neutral to alkaline soils.

  • Supplies readily available phosphorus and ammonium nitrogen to crops, crucial during planting and early growth.​

  • Used as a starter fertilizer for cereals, corn, pulses, fruits, vegetables, and pasture sowing.​

  • Ideal for band placement or surface broadcasting in the soil; also suitable for suspension fertilizers and fertigation systems.​

  • Enhances root development, establishment, flowering, and fruit setting across a range of crops.​

  • Compatible with most fertilizers and micronutrients (but avoid mixing with calcium- or magnesium-containing products in solution).​

  • Delivers nitrogen in ammonium form for slow, controlled uptake with reduced leaching risk.​

  • Acidifies the soil surrounding the fertilizer, improving phosphorus availability and reducing ammonia loss to air.​

  • Safe for direct seed placement—low risk of seedling injury compared to some high-ammonium fertilizers.​

  • Highly water-soluble, easy to handle and blend, suitable for use in precision agriculture.​

  • Free from chloride and heavy metals, safe for crops sensitive to salts.

Storage:

  • Store MAP in a cool, dry, well-ventilated area away from moisture and direct sunlight; product is hygroscopic and may cake if exposed to humidity.​

  • Use sealed containers or packaging (preferably in original bags or lined bulk bins) to maintain quality.​

  • Keep away from incompatible materials (alkaline substances, oxidizing agents); do not mix with calcium or magnesium fertilizers in solution.​

  • Palletized storage is recommended to minimize contact with the floor and maintain air circulation.​

  • Ensure proper labeling and regular inspection for damaged bags or contamination.
