Product Description
Sulfur coated urea is a kind of inorganic coated slow-release fertilizer, which takes sulfur as the main coating material and wraps granular urea to realize slow-release and controlled-release of nitrogen. Release nutrients continuously and stably to meet the nutritional needs of crops and improve yield and quality. After the urea is coated with sulfur, wax sealant is sprayed to seal the cracks and reduce the degradation of sulfur film by microorganisms. Finally, a layer of active clay is applied to make the surface smooth. SCU can provide the plants with medium amount of elemental sulfur, which is more suitable in the sulfur deficient areas. Sulfur coated urea has a unique color, which is suitable for all kinds of soil and crops. In addition, the unique sulfur nutrients in the coated urea can control the release rate of nutrients. The law of nutrient release is consistent with the law of crop fertilizer demand. After coated urea is applied to the soil, sulfur will slowly oxidize into sulfur dioxide and sulfur trioxides, and then react with water to generate sulfuric acid, making the soil around the fertilizer acidified; after slowly released urea is transformed into ammonium bicarbonate or ammonium carbonate, it will turn into stable ammonium sulfate, preventing the volatilization of ammonium. All of these can reduce the loss of nitrogen and improve the effect of nitrogen fertilizer. Compared with ordinary fertilizer, it also improves the utilization rate of fertilizer, has a higher cost performance, and is welcomed by the majority of users.
