It became available during the 1960s, and has since been widely used on both commercial crops, … Diammonium Phosphate (DAP) DAP is the most widely used phosphate fertilizer among growers today. Typically, we need approximately 1.5 to 2 tons of phosphate rock, 0.4 tons of sulfur (S) to dissolve the rock, and 0.2 tons of ammonia for the production of DAP. Research has also shown that phosphorous can greatly improve the health of crops when applied at the early stages of plant growth, after germination. Therefore, if we add this fertilizer to the soil, it can create an alkaline pH around the fertilizer granules that dissolve in soil water; thus the user should avoid adding a high amount of this fertilizer. © PhosAgro Group of Companies 2001 — 2020, 119333, Bld 1, 55/1, Leninsky Prospekt, Moscow, Russian Federation.

Diammonium phosphate (DAP) is the world’s most widely used phosphorus fertilizer. It’s highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. In alkaline soil conditions, one of the ammonia molecules in DAP will revert to ammonia, making it an excellent fit for low pH or alkaline soil. The effects last for several years. Bhd., incorporated in the year 2000 has experienced tremendous growth in this industry. 1.

Therefore, the nitrogen in DAP is considered a ‘delayed’ release nutrient, and will take longer than phosphorus to reach the plants. It's made by combining ammonia and phosphoric acid. In alkaline soil conditions, one of the ammonia molecules in DAP will revert to ammonia, making it an excellent fit for low pH or alkaline soil. Granules can be white, grey or black (with tones) DAP contains 18% of nitrogen in ammonia form and 46% of phosphours as ammonium phosphate (exact formula can differ slightly depending on producer) Ammonia nitrogen is not leached from soil, is slowly uptaken by plants and facilitates phosphorus uptake, limits excessive uptake of potassium. What is DAP Fertilizer It is widely used among farmers in the production of grain and row crops, such as corn, wheat, rye, and some lawn grasses. Diammonium phosphate (DAP) NP 18:46. It is highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. What Are the Different Types of Agricultural Fertilizer. Some bags may also contain up to 2% sulfur which also adds nutrients to the soil. The standard nutrient grade of DAP is relatively high, at 18-46-0, so fertilizer products with lower nutrient content may not be labeled DAP. Such statements should not be relied upon. When transporting in closed decked vessels, the fertilizer shall be packed in bags. But it also makes them toxic. Avoid using DAP with any Zinc based fertilizer as they can react and form Zinc Phosphide which is a toxic poison. Therefore, it is an important source of all three primary nutrients that a plant requires for its growth, development and proper functioning. Actual events or results may differ materially. For example, 10-10-10 indicates that the fertilizer provides 10% of each nutrient. Banding is similar, but a row is dug down one length of plants instead of around each stalk individually and then filled with pellets.

When using as a starter on bare lawns, apply before seeding. Diammonium phosphate fertilizeris a plant food that is rich in the mineral phosphorus. Terms of Use and Privacy Policy: Legal. Best solid granular fertilizer to provide crops with phosphorus and nitrogen that are easy to uptake. Like any other industry, we have our ups and downs. DAP itself is alkaline with a high pH, exceeding 7.5. To prevent such damage, users should avoid placing high concentrations of DAP near germinating seeds. DAP also acts as a fire retardant. Foliage growth is typically increased as well when such a phosphorus heavy fertilizer is applied, making diammonium phosphate fertilizer a popular choice for most farmers.
