Coastal ‘Tiger Mottle’ Soils , Simpson, Southwest Victoria, Australia
Location: flat, coastal plains,
Heytesbury Settlement, Simpson, Western District, southwest Victoria
Values for these soils:
– Food production -soil produces pasture mainly used for dairying, in a high rainfall zone (600-1000 mm/yr)
– Research – as a window into the geologic history of the formation of the soil from the regolith below
– Aesthetics- beautiful ‘art’ created by soil formation process
Challenges for Tiger Mottle Soils:
– Lacking in copper
– Prone to waterlogging due to water perching on the clay subsoil and saturating the A2 and surface soil.
– Cattle trampling the wet soil cause pugging/poaching of the surface which then aggravates the drainage problem and reduces pasture growth and utilization as feed and so milk production
– Subsurface hazards for infrastructure placed underground
