UDP: Background and Benefits
v Urea is the most common
nitrogen fertilizer for rice
v 1-3 g briquettes (USG)*, in
root zone at transplanting
v Slower release = nutrient
use efficiency improves
v Negligible losses to air
and water
* USG—Urea Supergranule

How to Prepare USG
Prilled Urea
Rollers
Briquettes
USG is produced
from prilled or
granular urea by
pressing the
urea with rollers
in a briquette
machine of 1.8
