Ⅰ. SCU can help reduces the application of nitrogen and increase the utilization of fertilizer.
1．Ordinary urea can only last for 7 day, but SCU can last for 8 weeks in soil. It can make nitrogen fully released.
2．SCU can reduce the numbers of applications from ordinary urea’s 2-3 times to only 1-2 time, the amount of fertilizer can also be reduced by half.
SCU makes controlled-release of nitrogen possible; it can greatly increase the utilization ratio of nitrogen, the most by 100%. Therefore it can considerably cut the cost of agriculture production and better protect the environment.
Comparison on effect using ordinary urea and SCU:
|
Application Area |
Paddy output
(kg／hm) |
Output increased

Ordinary Urea |
4911 |
1677 |
15.5 |
SCU |
5972 |
2378 |
21.9 |
The experiment shows that utilization of Nitrogen can reach 50% if SCU used in maize, sunflower and tomato. While it is only 1% if ordinary urea is used.

Ⅲ. SCU can help improve the quality of produce:
With SCU being used, oil content of peanut increases by 6.5%, Dl-Methionine increase by 40.9%. Resolvable sugar in grapes and tomato increase by 10.0% and 1.1%. Vitamin C increases by 58.5% and 12.6%. Acidity in grapes decreases by 11.7%. Garlic oil content in garlic can also be considerably increased. Flour from SCU fertilized wheat features better baking properties and the size of bread can increase by 42.6%.
Soybean: SCU (L)

Ⅳ. SCU can act as soil regulator to ameliorate Saline Alkaline soil.
After the urea in SCU is released, the sulphur shell can store water and air molecule (Oxygen) and so increase the ventilation of soil. And it can neutralize basic group in soil so as to ameliorate Saline Alkaline soil. SCU has been used in many countries such as U.S., Spain and Canada. Many examples prove the effect of improvement of Saline Alkaline soil.
Ⅴ. Save labor cost and lower production cost:
One application satisfies the needs of plants through all stages of growth. With agriculture labor increasingly becoming expensive and short in supply, great savings on labor, material can be achieved, resulting in a better productivity SCU. When used in some certain crop, enjoy its unique advantages. For example, in sugar cane planting, the growth period of sugar cane spans a few months. Mechanized application of fertilizer becomes hard after cane crest grow closed. But one time application of SCU at early stage of plant growth can satisfy the needs of the whole life time. So SCU has earned itself popularity among sugar cane farmers. Likewise strawberry growth inside plastic film is hard to give fertilizer, so more than 70% of strawberry farmers use SCU.
Ⅵ. SCU can prevent potential plant injury due to over application and help
exterminate pest and bacteria and strengthen plant's drought resistance and cold resistance.
SCU supplies not only nitrogen but also some sulphur to plants. Sulphur plays quite a few special roles in plant growth. It can strengthen plants' drought resistance, cold resistance and pest resistance, and quicken the maturity of plants. It promotes nitrogen fixation of peanut rhizobium, and increase protein content of its seeds. Sulphur is also important to composing of chlorophyll.
