[J]., 2014, 51(2): Fe and S Transformation Characteristics and Their Influential Factors in Simulated Mirabilite Soil YANG Xun 1, LI Yan 2, YUAN Dagang 1*, LI Xiaoying 1, CHEN Na 1, WANG Yiyan 1, CHEN Guanhua 1 (1 College of Resources, Sichuan Agricultural University, Chengdu , China; 2 Forestry Bureau of Yucheng District, Ya an, Sichuan , China) Abstract: In an indoor incubation experiment, Na 2 SO 4 contents of simulated mirabilite soil were determined, and then the effects of drying-submergence and different kinds and quantities of organic substances on Fe and S transformation in the soil were observed and discussed. The results showed that drying/submergence and organic substances had no significant effect on Fet and Fed. However, submergence and the quantities of organic substances had significant effects on Feo, Fep, Fe( ) and Fea. Moreover, Fe( ) and Fea were significantly affected by organic substances as well. Submergence and organic substance both could promote S transformation in the soil. Fe and S transformation was realized by direct reaction of organic substance, on the other hand, by changing the conditions of soil redox regime including Eh and TARM. Besides, there was a coupling relationship between the transformation of different forms of Fe and S in the soil. Key words: Simulated mirabilite soil; Fe; S; Drying/Submergence; Organic substance
