Abstract
(1) 由供試煤之一般分析結果獲知粉炭與亞炭、泥炭之成分不同，粉炭對一般化學試藥甚為安定，如鹼可溶性的腐植酸為量甚少，泥炭及亞炭之腐植質則多為鹼可溶性者。對一般化學試藥比較脆弱，故如施用前於土壤中則其分解速度必遲緩無疑，以煤為肥料製造之原料要在利用其腐植質，故煤之選擇素以(1)水分含量高(2)灰分少(3)鹼可溶性腐植多者為宜。
Efforts has been laid in order to introduce peat and low grade coal as a fertilizer resource. Former researches carried in foreign countries were investigated and it was found that preperation of ball fertilizer seems preferable in Taiwan. In 1953, a salient availability of the ball fertilizer was indicated in Japan. This fertilizer having a size as an olive was prepared by moltening the mixture of peat and Chemical fertilizers. It was learned that peat was used as an organic adsorbent to hold N, P, & K elements, thus can prevent their loss from leaching.
