Transformation characteristics of sulfur forms in acid sulfate soils under different soil water conditions

Abstract

Abstract: Aimed to detect the quantitative impact of soil water condition on the transformation of sulfur forms in acid sulfate soils(ASS),a simulation test was made with 8 treatments.The results indicated that water was an important factor affecting the transformation processes.Wet but not inundated or over dried condition was benefit to the oxidation of pyrite S and the formation of water soluble S (WS-S) and exchangeable S (Ex-S) in ASS.In the three treatments with different inundated and drained off cycles,soil pyrite S content averagely decreased 1.29～3.20 g·kg^-1 during a single drained off period,while soil WS-S and Ex-S contents averagely increased 0.90～1.63 and 0.58～1.47 g·kg^-1,respectively.During inundated period,soil pyrite S content was relatively stable,but soil WS-S and Ex-S contents were decreased significantly due to the dilution of water.It was suggested that the total S(mainly WS-S)of ASS was discharged in drainage process,and the accumulative amount of the discharge and the transformation of the S forms were associated with the length of the inundated and drained off cycles.The dynamics of Jarosite S,organic S and element S in all treatments were also discussed here.
