Usage:
More than 90% of world industrial production of Urea
is destined for use as Nitrogen–release fertilizer. Urea
has the highest Nitrogen (N) content of all solid
nitrogen content of all solid nitrogenous fertilizers in
common use. Therefore, it has the lowest
transportation costs per units of nitrogen nutrient. The
standard crop–nutrient rating of urea is 46 – 0 – 0. The
most common impurity of synthetic urea is Biuret,
which impairs plant growth.
Urea is usually spread at rates of between 40 and 300
Kg/HA but rates vary. Smaller applications incur lower
losses due to leaching. During summer season, Urea
is often spread just before or during rain to minimize
losses from volatilization (A process wherein Nitrogen
(N) is lost to the atmosphere as Ammonia Gas). Due
to the high Nitrogen concentration in Urea, it is very
important to achieve an even spread. The application
equipment must be correctly calibrated and properly
used.

Thank you.
