Sulfur is considered to be the forth important nutrient element
and its transformation greatly affects the growth of plants.In this paper
sulfur speciation in different soils is researched.Effects of long-term fertilization in different combinations were studied by sulfur K-edge XANES of the soil samples
and the proportions of S at different oxidation states were determined by fitting the sulfur K-edge XANES spectra.The results indicate that the soil samples contained all kinds of sulfur states
i.e.the most reduced S
intermediate S and highly oxidized S
with the highly oxidized S being the largest proportion.The contents of total sulfur are different in soils in different long-term fertilizer experiment
and both the rates and contents of different oxidation states change.
