DAP (stands for Di-Ammonium Phosphate) fertilizer is a commonly used plant nutrient booster used across India. Further speaking, it contains high compositions of Nitrogen (N) and phosphorus (P). Additionally speaking, these two nutrients are responsible for plants’ growth and colour, respectively. Henceforth, fertilizer is one of the most popular choices of farmers interested in increasing crop yield and health with sustainability.
Further speaking, the DAP fertilizer is oftenly founds in its usage in vegetables, fruits, grains, etc., plantations. In addition to the above facts, its quick water-dissolving capacity makes it more versatile and quickly absorbable by plants. Speaking about the importance of DAP in agriculture, the plant’s nutrient uptake booster has two essential minerals, as already discussed. Additionally, these minerals are part of plants’ DNA and chlorophyll and help in growth and reproduction.
As we all know, Nitrogen (N) in plants plays an important role in their growth. Further speaking, the other part of DAP fertilizer includes Phosphorus (P) which is responsible for root growth. Furthermore, phosphorus is also a part of chlorophyll responsible for a plant’s colour and food production.
Henceforth, in this blog, we will discuss different verticals of DAP fertilizer. The discussion will include its chemistry, benefits, application, choice, types, effects, and economics. So, stay tuned till the end to get the full projection. Let’s dive in.

Chemistry and working of DAP fertilizer
Speaking of the chemistry behind the production of DAP (Di-Ammonium Phosphate) Khad, it has the chemical formula (NH4)2HPO4. The nitrogen in it is in the form of Ammonium (NH4)+, which is readily absorbed by the plant’s roots as it is a chemically active ion.
Speaking a bit more, The ammonium found in the DAP compound is also a chemically active ion and absorbed by plant roots. Further speaking, the ion ammonium, once absorbed, used in the production of amino acids. Further speaking, this particular ion is responsible for a plant’s growth and development. Talking more about the ammonium ion, it is less likely to drain away with irrigational water.
Further speaking, the Phosphorous of DAP fertilizer is found in the compound in the form of phosphate (HPO4)-2, which plays an important role in RNA and DNA synthesis. Furthermore, phosphate is known as an energy transferer in plants.
Henceforth, the fertilizer works by quickly dissolving in irrigational water. Furthermore, once dissolved and fed to plants, it breaks down into the above-explained ions. Furthermore, these ions are readily available to chemically react with roots and other minerals present in the soil. Henceforth, after breaking down and breaking into individual ions and/or minerals, these are absorbed through the roots of the plants.

What are the benefits of using DAP khad?
There are several benefits of using DAP fertilizers. Below are the benefits mentioned in bullets.
1. Increase in crop yield
DAP fertilizers are essential for those areas that lack proper nutrients and minerals in the soil. Henceforth, boosting nutrient-capturing capacity is known to increase crop yield significantly.
2. Enhanced plant growth
The khad increases plant growth by providing the essential nutrients needed in a plant’s growth and development. Further speaking, highly concentrated Di-Ammonium Phosphate fertilizer encourages photosynthesis in plants. Henceforth, increased growth is observed in plants.
3. Highly reactive compound
DAP is a highly reactive compound and quickly dissolves in water. Henceforth, it is readily available for absorption through plants’ roots.
4. Enhanced root development
The phosphate ion-containing phosphorous is essential for the development of strong roots that are important for plant growth. Further speaking, these strong roots help a plant withstand drought and other rough water conditions.
5. Versatility
Speaking of the range of usage of compound DAP it is wide and includes cereals, grains, fruits, and vegetables.
Henceforth, conclusively speaking, the DAP fertilizer is a well-known choice among farmers due to its multiple benefits.
Methods for proper application of DAP fertilizer
The proper application of DAP khad is necessary for ensuring the right amount of nutrients and their absorption. Furthermore, it also avoids overuse or waste of fertilizer. Below are some of the methods necessary for the proper application of DAP fertilizer.
1. Soil testing and interpretation
Before the application of the khad, it is equally important to test the soil’s need for nutrients. Additionally speaking, the Department of Agriculture & Cooperation and Farmers Welfare, Government of India, provides soil testing solutions across the country.
Henceforth, a farmer in India can easily opt for soil testing. This helps us know the exact requirements of soil and the apt amount of fertilizer required.
2. The right dose
After soil testing, since the nutrient need of the soil is quite clear, the right dose of the fertilizer calculated. The farmers in India can consult experts regarding the matter by calling the Kisan Call Centres (1800-180-1551) meant to assist farmers. The call centre controlled and funded by the Ministry of Agriculture in India and is home to agricultural experts.
3. The right time to apply DAP fertilizer
The right time for DAP in agriculture can vary from crop to crop. Further speaking, it depends on the crop being grown and the stage of growth.
4. DAP fertilizer application methods and requirements
DAP khad can be used in a plantation using a variety of methods, including broadcasting, banding, and side dressing. Furthermore, more specific methods depend on the type of crop or plantation. Further speaking, the DAP fertilizer application should be uniform across the crop area to ensure equal growth of each crop plant.
Furthermore, DAP is a compound that easily dissolves in water and gels well with moisture. Also, applying it to dry soil not recommended as it may hinder nutrient absorption, negatively affecting growth.
The importance and process of choosing the right DAP fertilizer
It recommended and important as well to choose the right DAP khad to ensure the right amount of nutrient uptake. Depending on the crop, the percentage of Phosphorous and Nitrogen may vary in the fertilizer. Below mentioned points are some important factors that affect the process.
1. Soil’s pH and applicable type of DAP Khad
The pH level of the soil is a major factor determining the percentage of constituents in the DAP compound. Further speaking, in acidic soils, phosphorous may dissolve easily, while in alkaline soils, ammonium ions containing Nitrogen may lost because of volatilisation. Henceforth, it is important to match the soil’s pH with the type of DAP fertilizer required or available for the crop.
2. A projection of overall nutrients in it
The overall constituents’ percentage in fertilizer may depend upon the manufacturer’s production process. Henceforth, choosing a DAP khad depending upon the right balance of constituents is equally important.
Further speaking, the particle size of the DAP compound can affect the dissolving capacity or the rate of dissolution and availability of the minerals. While smaller particles dissolve faster, they are susceptible to leaching. However, larger particles dissolve slowly but have enriched mineral composition. The right particle size depends on the soil type, climatic conditions, and the crop being grown.
3. The purity of the fertilizer
A DAP fertilizer should be pure and free of contaminants. Speaking specifically of contaminants, these can be potentially hazardous for a plant’s growth. Hence buy the fertilizer from Government authorities or authorised dealerships only.
4. The cost of the fertilizer
The cost of DAP fertilizer may vary depending on the quality of the manufacturing unit and the quantity & quality needed. Henceforth, choosing the right fertilizer that satisfies the principles of value for money is of utmost importance.
