摘要：

The seasonal sulfur dynamic of semisubmerged Salic Fluvisols was investigated in Neuwarpeler-AuBengroden (Southern North Sea coast) from August 1991 to October 1992. The study was mainly performed by sulfide-sulfur (HCl digestion) and sulfate-sulfur were measured, organic sulfur and pyrite-sulfur were calculated. The dominating sulfur fraction was pyrite, followed by organic sulfur sulfate and sulfide. The sulfide contents did not change remarkably in the course of the year. They were positively correlated with the chloride contents. The total sulfur contents were highest in summer and winter. They show two phases of pyrite formation. The redox potentials show a simultaneous reoxidation in summer.
