The argument by extension officers that the NPK fertiliser is superior to DAP because the latter does not acidify soils is highly debatable. First, we do not know the nutrient carriers that supply nitrogen in the NP fertiliser supplied by the National Cereals Board.
What is NPK value of DAP?
The composition of DAP is 18% Nitrogen and P2O5 46%. Within the same facility, Hindalco can also produce nitrogen phosphorus potassium (NPK) complexes as value-added downstream products. It can manufacture NPK complexes such as 10:26:26, 12:32:16 and 20:20:0.
Is DAP good for flowering plants?
DAP fertilizer is an excellent source of P and nitrogen (N) for plant nutrition. It’s highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. A notable property of DAP is the alkaline pH that develops around the dissolving granule.
Is DAP good for all plants?
Most concentrated phosphate-based fertilizer. It is perfect for any agriculture crop to provide full phosphorus nutrition throughout crop growth and development, as well as a starter dose of nitrogen and low sulphur.

Can I spray DAP on plants?
Spray 2% DAP at the time of first appearance of flowers and a second spray at 15 days after first spray for enhanced seed set. Spray NAA 40 ppm at first flowering and a second spray after a fortnight to reduce the flower drop. NAA can be mixed with insecticides and fungicides.
What is the benefit of DAP fertilizer?
DAP fertilizer is an excellent source of P and nitrogen (N) for plant nutrition. It’s highly soluble and thus dissolves quickly in soil to release plant-available phosphate and ammonium. A notable property of DAP is the alkaline pH that develops around the dissolving granule.
Is DAP fertilizer water soluble?
DAP is a water soluble fertilizer. The soil pH temporarily reduces to 8.5 in areas where DAP initially reacts with soil. DAP may produce free ammonia in high pH soils, which may cause seed injury if placed too close to seed rows.
How long does DAP fertilizer take to work?
The reaction will begin to occur 24 hours after application and be complete within 2 to 5 days. The reaction time is slowest in cold, waterlogged conditions. It is hydrolysed in the soil by the enzyme urease to furnish ammonium and then nitrate ions.
Can I use NPK for potted plants?
Application of this fertilizer crystals is very easy and depends on the size of the pot. For Larger pots of 16 – 18 inch diameter, you can use 15 to 20 crystals, once, every 15 days. For 12 to 14 inch pot diameter, you can use arounf 10 crystals every fortnightly.

What is a good NPK fertilizer?
Studies have found that the ideal NPK fertilizer ratio of those nutrients for flowering plants is 3-1-2. (That’s 3% Nitrogen, 1% phosphorus & 2% potassium.) So look for that ratio on the label of packaged fertilizers; anything close to a 3-1-2, a 6-2-4 or a 9-3-6 should be ideal.
