You can purchase fertilizer urea as prills or as a granulated material.
In the past, it was usually produced by dropping liquid urea from a prilling tower while drying the product. The prills formed a smaller and softer substance than other materials commonly used in fertilizer blends.
Today, considerable urea is manufactured as granules. Granules are larger, harder and more resistant to moisture. As a result, granulated urea has become a more suitable material for fertilizer blends.
physical form
You can apply urea 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.
Urea manufacturing releases few pollutants to the environment.
When properly applied, it results in crop yield increases equal to other forms of nitrogen.
advantages
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.
The key to most efficiently using urea 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.
