Development of slow/controlled-release fertilizer production processes
Thread Content
Slow/controlled-release fertilizers are environmentally friendly, resource-saving, and represent new high-tech products that contribute to the rapid development of agriculture, rural areas, and farmers. Based on the principles of control structure, they are divided into externally controlled and internally controlled types. The externally controlled type, also known as the encapsulation type, is further divided into resin encapsulation and sulfur encapsulation, etc.; the internally controlled type includes polyurethane types and urea-formaldehyde resin types. Production processes include drum, tray, fluidized bed, and bubbling bed types. Everyone is welcome to participate actively!
Outer packaging is quite common, while inner packaging is hard to say about
Well, not bad :) It’s usually covered on the outside; it can’t really be called high-tech
Slow-release and controlled-release fertilizers have been included in the 12th Five-Year Plan. In China, companies such as Jindongda are active in this area, and the United States has also introduced measures to encourage the development of such fertilizers. However, at present it is still difficult for them to become the mainstream; the environmental impact of slow-release and controlled-release fertilizers remains unclear
I’m actually hearing about the classification into external control type and internal control type for the first time
One thing is clear: improving the efficiency of fertilizer use reduces its loss, which in turn contributes to environmental protection
