Ammonium Dihydrogen Phosphate, commonly known as MAP, is a widely used chemical compound in agriculture, particularly as a fertilizer. With the Chemical Abstracts Service (CAS) number 7722-76-1, MAP is a source of essential nutrients for plants, providing both nitrogen and phosphorus in a form that is easily absorbed by crops. Its primary function is to promote plant growth and enhance agricultural productivity. Ammonium Dihydrogen Phosphate MAP CAS 7722-76-1

Composition and Properties

Ammonium Dihydrogen Phosphate is a crystalline salt composed of ammonium (NH4+) and phosphate (H2PO4-) ions. The chemical formula for MAP is (NH4)H2PO4. It is highly soluble in water, making it an effective nutrient source for a variety of crops, especially in soils that are deficient in these essential elements. MAP is typically produced through the reaction of ammonia (NH3) with phosphoric acid (H3PO4), resulting in a high-quality, concentrated fertilizer.

MAP has a nitrogen content of about 11% and a phosphorus content of approximately 48%. This makes it one of the most efficient fertilizers in terms of providing both of these key nutrients simultaneously, which are essential for healthy root development and overall plant growth.

Applications in Agriculture

MAP is predominantly used as a fertilizer in agriculture due to its high phosphorus content, which is vital for the development of plant roots, flowers, and fruits. Phosphorus is also crucial in energy transfer within the plant, aiding in photosynthesis and the formation of vital compounds like DNA and RNA. The ammonium component provides nitrogen, which is essential for protein synthesis and overall plant growth.

MAP is suitable for a wide range of crops, including cereals, vegetables, and fruits. It can be applied to both soil and hydroponic systems, and it is commonly used in the early stages of plant growth to boost root development and ensure a strong start for the crop.

Safety and Handling

While MAP is generally safe to handle, it should be stored in a cool, dry environment away from incompatible substances like strong acids and strong oxidizing agents. The compound can be harmful if ingested or if its dust is inhaled, so proper safety precautions, including protective clothing and ventilation, are recommended during handling and application.

Conclusion

Ammonium Dihydrogen Phosphate (MAP) CAS 7722-76-1 plays a vital role in modern agriculture. By providing essential nutrients to crops, MAP supports healthier plants, higher yields, and improved food security. Its widespread use in fertilizers highlights its importance in the global agricultural industry, contributing to sustainable farming practices worldwide.
