Dangote Urea Fertilizer: Usage, Composition, Advantages & Storage
As Dangote Urea Fertilizer starts operation and distribution on the first week of April, 2021. We are glad to inform you that we are part of their Dangote Fertilizer Distributor in Lagos and Nigeria as a whole.
Dangote Urea Fertilizer is a granule fertilizer. Granules are larger, harder and more resistant to moisture. As a result, Dangote granulated urea has become a more suitable material for fertilizer blends.
Advantages
- You can apply Dangote Urea Fertilizer to soil as a solid, solution or, for certain crops, a foliar spray.
- Usage involves little or no fire or explosion hazard.
- Urea’s high analysis – 46 percent N – helps reduce handling, storage and transportation costs over other dry N forms.
- When properly applied, it results in crop yield increases equal to other forms of nitrogen.
Usage
The key to most efficiently using Dangote Urea Fertilizer is to incorporate it into the soil during a tillage operation. You can also blend it into the soil with irrigation water. As little as 0.25 inches of rainfall is sufficient to blend urea deep enough into the soil so ammonia losses won’t occur.
Nitrogen from urea can be lost to the atmosphere if fertilizer urea remains on the soil surface for extended periods of time during warm weather.

Applying to growing Crop
Urea can be applied to sod crops, winter wheat or other small grains. However, make this application in cool seasons. During warm periods (60 degrees Fahrenheit or above), urea in contact with vegetative material tends to give off ammonia.
If urea must be applied on grass pastures in the summer, apply when there’s a high probability of rainfall.
Foliar sprays
You can also apply urea as a foliar spray on some crops, such as potatoes, wheat, vegetables and soybeans.
Urea is highly water soluble. At normal atmospheric temperatures, approximately 1 pound of urea can be dissolved in 1 pound of water.
Research indicates that urea should contain no more than 0.25 percent biuret for use in foliar sprays. For many crops, the quantity of nitrogen applied at one time shouldn’t exceed 20 pounds of nitrogen per acre.
Storing Dangote Urea fertilizer
Urea isn’t combustible or explosive. Under normal circumstances, it can be safely stored with no loss of quality.
Storage tips
Don’t use small or fast-moving augers to move granular urea. Urea particles are generally soft and abrasion can break the granules. Use belt conveyors whenever possible.
Also, don’t store urea with ammonium nitrate. When in contact, these materials rapidly absorb water when the relative humidity is above 18 percent. Table 9 indicates the relative humidity at which urea and ammonium nitrate absorb moisture from the air.
Losing Dangote Urea Fertilizer to Air
Urea breakdown begins as soon as it’s applied to the soil. If the soil is totally dry, no reaction happens.
But with the enzyme urease, plus any small amount of soil moisture, urea normally hydrolyzes and converts to ammonium and carbon dioxide. This can occur in two to four days and happens more quickly on high pH soils.
Unless it rains, you must incorporate urea during this time to avoid ammonia loss. Losses might be quite low in the spring if the soil temperature is cold.
The chemical reaction is:
CO(NH2)2 + H2O + urease → 2NH3 +CO2 (urea)
The problem is the NH3, because it’s a gas. However, if it’s incorporated, it acts the same as incorporated anhydrous ammonia. Also, half of 28 percent liquid N is urea. The same thing happens with this half as with regular urea.
