With the continuous improvement of agricultural science and technology, the promotion of high-yield varieties, the improvement of land re cultivation index, the vigorous development of economic crops, flowers and urban greening. The phenomenon of crop growth and soil nutrient ecological balance is becoming more and more serious, and the phenomenon of crop sulfur deficiency is becoming more and more serious.
Sulfur urea has become a popular fertilizer product in the market. It is coated with sulfur and other trace elements on the outside of urea by coater and pulverizer, so that the nutrients of fertilizer are released slowly. It is different from the technology of rotary drum granulator of compound fertilizer.
Why should sulfur coated urea fertilizer be used
1. sulfur coated urea can improve the utilization of fertilizer, similar to the granular fertilizer made by disc granulator, and can control the release rate of fertilizer nutrients. Especially, the utilization rate of nitrogen fertilizer can be greatly improved, the efficiency of fertilizer can be nearly doubled, and the agricultural investment can be greatly reduced and the environment can be protected.
2. increase crop yield greatly. The application of different soil and crop has a good effect on the yield.
3. the sulfur coated urea fertilizer can improve the quality of the crop products.
4. fertilizer can be used as soil conditioner, and the effect of the treatment of saline alkali land is good.
5. reduce labor input.
The application of sulfur coated urea fertilizer at one time can meet the needs of different growth stages of crops. With the high cost and shortage of modern agricultural labor cost, the application of sulfur coated urea in some crops also shows its characteristics.
For example, planting sugarcane, because the cane grows for months, it is not easy to mechanized fertilization after the crown is closed. In the early stage of self-growth, single fertilization can meet the needs of crops and is welcomed by sugarcane farmers. Strawberries grown in plastic mulch are also easy to apply nitrogen, so 70 percent of California’s strawberry growers use sulfur coated waste.
We provide a complete production line of sulfur coated urea, as well as the chemical fertilizer production equipment such as disc granulator, drum granulator, double roller granulator, coating machine, packaging machine and so on.
