This experimental study was carried out to examine the utilization of the anthracite ash as a fertizer. It was found that the ash had very small amount of the soluble matters in 2% citric acid solution therefore it is proved ineffective as a fertilizer. When the small amount of calcinated dolomite was added to the anthracite, it was observed that the resulting ash showed much increased solubility of magnesium, calcium, sulfur and silica etc in the citric acid solution. So it is concluded that the ash of the mixture of anthracite and calcinated dolomite would be one of the useful soil-conditioner and supplyer of nutrients
