Can highly water-absorbing silicon-containing minerals be used as fillers in slow-release fertilizers?
Thread Content
I would like to ask the experts: our company has a type of mineral with high water absorption and micropores. Could it be used as a filler in slow-release fertilizers? What are the characteristics of the fillers in slow-release fertilizers? Thank you!
It has nothing to do with sustained release. . . . Check out the principle of sustained release. . . .
Is encapsulation the only way to achieve slow-release effects? This mineral has multiple layers of micropores; if fertilizer molecules are placed inside these pores, it might be possible to achieve a slow-release effect during the application of the fertilizer. It’s just my personal opinion – I’m not sure if it makes sense.
