Cosmetic Grade Urea

Efficently using urea

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.

Losing urea to air

Cosmetic Grade 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.
