Sulphur Coated
Urea 31-0-0 (SGN 150)
Sulphur coated Urea (SCU) is manufactured by coating Urea, first with sulphur,
then with a sealant. The amounts of Sulphur and sealant determine the slow
nitrogen release characteristics of the product.
The following analysis is applicable at the point of SCU.

Slow release
properties: Guaranteed maximum urea N Release in 7 days (12
0f 31
units) 39.0%
Typical 7 day N
Release (8 to 12 of 31 units) 26.0% -39.0%
(The controlled
release characteristics are measured by determining the
amount of urea
nitrogen which dissolves when a 50 gram sample of product is
immersed in 250
milliliters of water at 37.80 C for seven days
