Wood ash is a waste product of biomass combustion, but it contains substantial amounts of plant nutrients such as calcium (Ca), potassium (K), magnesium (Mg), and phosphorus (P) [1,2,3].This composition of wood ash makes it a valuable fertilizer to increase the yields of crop and forest products [1, 4, 5].Previous studies revealed that wood ash has an acid-neutralizing capacity, expressed as .
