NPK Fertilizer With Slow Release Fly Ash [PDF]

The Journal of Pure and Applied Chemistry Research, 2018
Fly ash is the solid of the remaining coal combustion carried along with the exhaust gas and captured by the air controller. Fluids in fly ash are Al2O3, SiO2, Fe2O3, CaO, MgO, Na2, and SO3 which are similar to zeolites. So that fly ash can be used as a substitute for zeolite for various carrier of fertilizer.
