Monoammonium Phosphate 12:61:00

Monoammonium Phosphate is one of the best sources of potassium. It is a 100% water-soluble fertilizer. Once it is fed to the crops it makes sure that all plants are able to withstand all the vagaries of nature. If a plant does not have phosphorous, Monoammonium Phosphate offers the best low-cost solution for the farmer. Its good nitrogen content makes it valued for the fauna.

Chemical Specification of Monoammonium Phosphate 12:61:00

12% of nitrogen,
61% of phosphorous
0% of potassium

Benefits of Monoammonium phosphate:

1. It is 100% water soluble fertilizer & can be used for fertigation or foliar sprays.
2. It offers superior nutrition as it provides highest nutrients (i.e 73%
2. It is better fertigation solutions keeping the pH efficiency stable at around 4.5
4. It has urea free Nitrogen hence it can give better availability of Nitrogen through ammonia (as it will prevent leaching via fertigation systems).

Compatibility with other fertilizers

It can be mixed with any other fertilizer that does not contain calcium. It is capable of buffering fertigation. The pH level remains stable, usually at 4.5 which is ideal in environmental conditions where plants grow. It adds to the micro availability of the other nutrients in the soil. When it is added to pure h3PO4, it becomes a clear solution that can be added to irrigation water. This is used as a foliar spray. It becomes a blended fertilizer for liquid based products.

Applications of Monoammonium Phosphate 12:61:00

It can also be applied as a fire retardant for paper, timber, and fabric. It can be a coating agent for fire prevention. The dry powder of fire extinguishers contains this ingredient. In the food processing industry, it is nourishment for grading foods. In case of agricultural industry where its most benefits are seen, it is applied below the surface of the soil. Farmers spread it across the farmland during the tilling process. It is an essential ingredient of suspension fertilizers. The P2O5 equivalent content of high-purity MAP is usually 61%. As long as it is used in the first stages, i.e. tilling process, it is an important nutrient.
