SCU (Sulfur
Coated Urea)
As a hi-tech controlled/slow release fertilizer, Sulfur coated
urea (SCU) has both effects of nitrogen and sulfur fertilizers.
It is being used in rice, wheat, corn, vegetable, bamboo, fruit
and garden with such features as fertilizer-saving, labor-saving,
output-increasing, income-increasing and environment improvement.
As one new kind of bio-fertilizer, it has excellent social
and economic benefits.
A, Increasing the availability of fertilizer
In have rain condition, the
nitrogen loss per mu (15kg nitrogen) is 0.53~0.6kg, which is
similar to the land without nitrogen, which the normal loss
is 2.13~2.4kg/hektare. In the regions where lose nitrogen easily,
the availability is 50% (4% for
normal urea) in lands.
B, increasing the outputs
It can improve outputs of crops all kinds of lands.

Sulfur coated urea can offer good effects
for rops with long growrh period , crop in sand lands. It also
offer good effects to green lands, pasturage and ornamental.
C, improving the quality of crops
Sulfur coated urea can improve
the quality of crops, which is related to the demands
of plant on sulfur and the dosage of fertilizer.
For example, sulfur can increase 10.0% and
4.1%. soluble sugar of grape and tomato, 58.5% and 12.6% of
vitamin C, and the sourness of grape is lowered 14.7%, it also
can increase the assay of garlic oil.
Sulfur also ocan offer another functions:
increasing the resistance of crop to freeze and drought, increase
the cometition of bean crop in grass, control the insect and
disease of plant, acclerating the growth and mature of crops;
it also can be used in wheat to improve the baking quality
of flour and taste.
Sulfur can increase the outputs of cole and
peanut, but also increase the assay of oil and protein in seeds;
unsaturated fatty acids can help heal heart disease and cancer,
and amino acids are very important to health.

D, used as soil regulator
After the uear is relaese, the sulfur sheel
can keep moiture air and increase the permeability of soil,
it alos can kill bacteria and dispel insects. It also can improve
soil in long-term application.
E, Saving labor and time, reducing the coat
of labors
It can meet the demands of growth in one-time
application. As to the crops with long growth period such sugar
cane, can offer engou fertilizer in every stage of growth;
moreover, it is hard to fertilize in the strawberry field coated
with membrane, so we can used SCU for the crops coated with
membrane, especillay for chilli and tomato in green house.

(pure).
