Abstract A study of the effects of low-level SO2 exposure on decomposition ofAgropyron smithii was conducted. Finely groundA. smithii litter was exposed to 220 μg m−3 SO2 continuously for five weeks. Respiration and total decomposition were measured. Sulfur dioxide exposure resulted in a 90 % reduction in decomposition rate during the initial phase of exposure and a 17% reduction during the latter phase. Differences in respiration rate were not observed. The reductions in decomposition corresponded to a previous report of reduction in the decomposition ofA. smithii and lowered soil pH with SO2 exposure in a field experiment (Dodd and Lauenroth, 1981).
