Primary Fertilizer & Supplement Materials

Di-ammonium Phosphate popularly known as DAP is a preferred fertilizer in India because it contains both Nitrogen and Phosphorus which are primary macro-nutrients and part of 18 essential plant nutrients.

DAP (NH4)2HPO4: Fertilizer grade DAP Contains 18% Nitrogen and 46% Phosphorus (P2O5). DAP is manufactured by reacting Ammonia with Phosphoric acid under controlled conditions in fertilizer plants.

Urea is a white crystalline substance with the chemical formula NH2-CO-NH2; it is highly water soluble and contains 46% nitrogen. It is used extensively as chemical fertilizer as well as for industrial uses. Government of India mandated all producers to coat urea with Neem Seed oil and fortify Urea.

Neem coated urea is created by utilising two best things available. First the urea created by technology from Air & Natural gas and second products from nature’s gift i.e. neem plant. Neem has proven Nitrification inhibition properties and hence slows down the release of nitrogen from urea and makes available nitrogen over a longer period with minimum loss of nitrogen thereby increasing nitrogen use efficiency. At our Hazira and Shahjahanpur Plants, Neem coated urea is produced by uniformly coating neem oil on prilled urea during the manufacturing process.

Product Description

Analysis: 46-0-0

Manufactured from reacting CO2 with ammonia, urea is one of the most commonly used Nitrogen fertilizers.

Properties:

Sold as granular and prilled product in various sizes (SGN)
Water soluble
White in colour

Application methods:

Broadcast (surface-applied) or banded (adjacent to the seedbed)
Generally used in NPK blends, along with micronutrients

Advantages:

Relatively easy to store and handle
Breaks down fairly quickly in the soil into a plant-available form
Has the highest concentration of N in a dry fertilizer product (46-0-0)
Blends well with most fertilizers

Drawbacks:

Hygroscopic properties so can bridge and deteriorate if stored for extended periods of time or in humid environments.
Risk of N volatilization when surface applied

Calcium Ammonium Nitrate can be considered as near-neutral in its effect on soil pH – and therefore can be used on soils that have a low pH without lowering further. This also means it is most suitable for using on perennial fruit crops (where soil incorporation of lime is normally difficult to achieve).

For use on perennial fruit crops (where soil incorporation of lime is difficult)

Is a nitrogen fertiliser which contains equal parts of fast acting nitrate-nitrogen and longer lasting ammonium-nitrogen.

Volatilisation of nitrogen from CAN is negligible, therefore the timing of the applications is flexible.

Can be considered as near-neutral in its effect on soil pH and therefore can be used on soils that have a low pH without lowering further.

CAN is a nitrogen fertiliser which contains equal parts of fast acting nitrate-nitrogen and longer lasting ammonium-nitrogen. This ensures a more continuous nitrogen supply to the crop and thus better efficiency of use, and also makes it suitable for unseasonal application during summer or winter.

What does NPK ratio mean?

The NPK ratio refers to the three numbers that indicate the percentage of nitrogen, phosphorus, and potassium in an NPK fertilizer. A 20-20-20 fertilizer, for example, would have 20% nitrogen, 20% phosphorus, and 20% potassium.

What is NPK fertilizer?

NPK fertilizer contains three essential nutrients needed for plant growth and overall plant health. These three essential nutrients include nitrogen (N), phosphorus (P), and potassium (K).

What is NPK fertilizer good for?

The nitrogen in NPK fertilizer is usefully for helping plants to growth leaves. Phosphorus, by contrast, helps to produce healthy flowers, buds, roots, and fruits. Potassium is used by plants to help sustain overall plant health.

NPK Fertilizer: What Does NPK Stand For?

All living organisms rely upon micronutrients to sustain their basic biological functions. Micronutrients include vitamins and minerals that are acquired from food sources and used by living organisms to grow, reproduce, and recover from illness and injury. In humans and animals, niacin, ascorbic acid, thiamine, calcium, and sodium represent familiar micronutrients found in foods.

Plants, like animals, also require micronutrients to help support their basic functions. The primary nutrients needed by plants include carbon, hydrogen, oxygen, and three essential minerals. Carbon is acquired from the atmosphere, while hydrogen and oxygen are derived from water.

To acquire the three essential minerals, NPK fertilizer represents the primary product used for supplementing the nutritional requirements of flowers, trees, grasses, and agricultural crops.
