Fertilizer 21 53 0 DAP Diammonium Phosphate

It is a product with high solubility in water, which ensures a rapid response to fertilization. As reaction fertilizer in the soil around

a granule acidification is generated that improves the utilization of phosphorus applied and available in the rhizosphere. Due to

its nitrogen content (present as ammonia), it is good for crops that require these nutrients in its initial phase.

1. The advantages of fertilizer 21-53-0 dap diammonium phosphate

l Fully water-soluble

l Consists of 100% plant nutrients

l Highly-concentrated source of phosphorus and nitrogen (as ammonia) for plants

l Free of chloride, sodium and other detrimental elements for plants

l Excellent for low pH or alkaline soils

l Suitable for the fertigation, foliar application and production of fertilizer blends and nutrient solutions

Compared with MAP: The ammonium present in DAP is an excellent N source and will be gradually converted to nitrate by soil

bacteria, resulting in a subsequent drop in pH. Therefore, the rise in soil pH surrounding DAP granules is a temporary effect. This

initial rise in soil pH neighboring DAP can influence the micro-site reactions of phosphate and soil organic matter. DAP is alkaline

with a high pH, exceeding 7.5. DAP is excellent for low pH or alkaline soils.

2. Compatibility fertilizer 21-53-0 dap diammonium phosphate

DAP is compatible with most water-soluble fertilizers, except for fertilizers containing calcium (Ca⁺⁺)

or magnesium (Mg⁺⁺). To apply DAP in combination with calcium or magnesium fertilizers, use two

fertilizer tanks. If only a single fertilizer tank is available, apply those fertilizers at different times.

3. Quantitative Nutrigation

Each kilogram of DAP in the tank provides 530 grams of phosphorus (P₂O₅) and 210 grams of

ammonium-nitrogen (N-NH₄).

4. Foliar Feeding

Foliar spray with DAP is effective in supplying phosphorus whenever quick response to deficient plants is required. It should be

considered a supplemental method to soil applied phosphorous and nitrogen (as ammonia)

1. Application Recommendations fertilizer 21-53-0 dap diammonium phosphate

Because of unique product characteristics, DAP can be applied through any irrigation system and onany growing medium.

Unlike phosphoric acid, DAP is moderately acidic. Therefore, it is not corrosive to fertilizer pumps or to irrigation equipment.
