165 rural lots across 1,684 ha in Greater Geelong. Dominant: Domestic Livestock Grazing.
Soil organic carbon is the headline indicator of soil health and productivity across the 165 rural lots in this suburb, alongside the land-system susceptibilities that shape what the land can carry.
National soil-grid values averaged across rural lots, with the dominant Victorian land system.
Soil values: Soil and Landscape Grid of Australia (CSIRO/TERN), ~90 m national soil grid, 0–30 cm depth-weighted. Land systems: Victorian land-systems mapping (Agriculture Victoria). Regional indicators — not a substitute for a site soil test.

Climate values are the average across rural lots in this area, from national long-term climate grids (rainfall and temperature normals, growing season and aridity).

Soil organic carbon, pH and texture come from the Soil and Landscape Grid of Australia; salinity, erosion and waterlogging susceptibility from Victorian land systems mapping. Planning overlays and zones are from the Victoria Planning Provisions. Land use is from the Victorian Land Use Information System, groundwater from the Victorian monitoring network, and terrain from the national elevation model. Market context is the published Valuer-General Victoria suburb median — a suburb indicator, never a property valuation.
