| Abstract: | The influences of different modifiers on the acidity of brown red soil in Xuancheng City of Anhui Province were studied. The results showed that white lime power, calcium carbonate power and dolomite power all worked well on improving brown red acidity and increasing cole yield, and the feasible applied amounts of modifiers should be 1125 ~ 1687.5 kg/hm2 of white lime power, 1500 ~ 2250 kg/hm2 of calcium carbonate power and 1500 ~ 3000 kg/hm2 of dolomite powder. |
