Abstract

Bottom ash (ash of coal) has been discarded as waste matter, but recently, because of its porous structure, trial use has been made of it as a soil amendment. In this paper, the characteristics of bottom ash, when used as a mendment, were examined.<BR>It is often pointed out that one of the problems with bottom ash is high alkalinity (over pH 9). However, the high alkainity of Bottom ash could be neutralized by mixing with masa soil (pH 5.6) and peat moss (pH 3.8). Bottom ash can improve the water retentivity of masa soil ; more importantly it increased soil water to the pF 1.8 to 2.8 range where it can easily be taken up by plants. It also showed good resistance to pressure. It is assumed that bottom ash could be used as a substitute for perlite.
