Sulphur Dioxide (SO2)

Sulphur Dioxide :: Improved grassland

Impact Type: Direct exposure to pollutant

Key Concerns:

While very large concentrations of SO2 may negatively effect grass growth, studies have shown that grasses may evolve a tolerance to high SO2 levels (Ayazloo and Bell 1981, UKCLAG 1996). The latter would imply that differential effects could be expected on permanent improved grassland than on resown swards and temporary grassland.

Sulphur Dioxide :: Arable & Horticultural

Impact Type: Deposition of pollutant

Key Concerns:

While very large concentrations of SO2 may negatively affect grass growth, studies have shown that agricultural grasses may evolve a tolerance to high SO2 levels (Ayazloo and Bell 1981, UKCLAG 1996). In the case of arable crops, this would require the specific planting of SO2 tolerant seeds.
