Sustained Release Resin Coated Urea

Resin-coated fertilizer is the first domestic jet-flow coating equipment developed by the Beijing Academy of Agricultural Sciences Research and Development by using special polymer organic materials to coat urea and ternary compound fertilizer under completely enclosed conditions. A resin film is formed on the outside of urea (compound fertilizer) to slowly release nitrogen (nitrogen, phosphorus, potassium). In the processing technology, the time and rate of nutrient release can be controlled by controlling factors such as material, coating time, coating thickness, and the size of the coating aperture, so that the product can be formed for 30 days, 60 days, 90 days, 120 days, The fertilizer effect of different days such as 150 days, 180 days, 220 days, and 270 days. The resin-coated urea (compound fertilizer) can be directly applied to some high value-added cash crops, flowers, and recreational lawns. The price of this fertilizer is lower than that of the United States, Israel, Japan and other foreign countries, so it is more competitive in foreign markets. At present, Sigli's long-acting controllable resin-coated fertilizer (urea) has been exported to Japan, South Korea, and the United Kingdom, North America, and other places, and have been registered in Japan and North America.

The long-lasting controllable resin-coated urea alone has a slightly higher application cost on general crops. It can be mixed with general compound fertilizers or combined with Sigli zeolite compound fertilizer to use on crops. It can be used as a base fertilizer application without additional topdressing. Among them, compound fertilizer can play the role of bottom fertilizer, and resin-coated urea can play the role of top dressing by controlling the release time.
