Abstract
무연탄 탄분을 비료로서 이용하기 위하여 연구를 하였다. 무연탄 탄분은 2% 시트르산 용액중에서는 가용성물질이 대단히 적으나 하소된 dolomite를 첨가한 무연탄탄분은 마그네슘, 칼슘, 황, 무수규산 등의 구용성 가용분이 많아 지므로 비료로서의 효과가 있음을 알았다.

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.
