Investigations of the influence of added organic matter content (rice straw or clover) on the reduction of added sulfate (8 meq/100 g soil) following submergence and incubation of 120 days gave these results: 1. In soils with native organic matter (humus) the rate of sulfate reduction was very low; it slightly increased with increased clay content of the soils. 2. The addition of undecomposed organic matter led to a complete reduction of the added sulfates within 120 days. 3. The varying C/N ratio of the added organic matter appeared to have no influence on the sulfate reduction. 4. As a qualitative indication of the reduction the soil darkened after three weeks of incubation, and an odour of H2S was detected.
研究添加有机物（稻草或三叶草）含量对淹水并培养120天后添加的硫酸盐（8毫当量/100克土壤）还原的影响，得到以下结果：1. 在含有天然有机物（腐殖质）的土壤中，硫酸盐还原速率非常低；随着土壤粘土含量增加，还原速率略有增加。2. 添加未分解的有机物导致在120天内添加的硫酸盐完全还原。3. 添加有机物的不同碳氮比似乎对硫酸盐还原没有影响。4. 作为还原的定性指标，培养三周后土壤变黑，并检测到硫化氢气味。
