Effects of three exposure levels of SO/sub 2/ (55, 100, and 170 ..mu..m/sup -3/) on the nutritive value of western wheatgrass were investigated. Significant increases in plant sulfur content were observed, both with time and level of SO/sub 2/ exposure. Plant ash content paralled the trends observed for sulfur concentrations. Nitrogen concentrations in western wheatgrass were not affected by SO/sub 2/ treatments. The increased plant sulfur content and decreased N:S ratios across treatments did not significantly affect forage digestibility as measured by in vitro digestible dry matter.
