Calcarosols (Australian Soil Classification) generally have a negligible or gradual increase in clay content with depth and the soil profile is calcareous throughout.
Calcarosols are not common in the region and occur mainly on dunefields along coastal regions both on the Bellarine Peninsula and between Ocean Grove and Lorne. These soils are generally sandy throughout and can contain large amounts of shell fragments. A small area of shallow clayey Calcarosols developed on limestone, occurs on the Bellarine Peninsula near Wallington.
Calcarosols in the Corangamite Region
This broad scale map presents an overview and should only be used as a general indication of the distribution of Calcarosols in the Corangamite region. It shows areas where Calcarosols are most likely to occur within the region. Note that other soil types may also occur within these mapped areas.
This map has been developed from work undertaken by Robinson et al. (2003) as part of the Corangamite Land Resource Assessment project. This work utilised existing surveys, remote sensing information and additional field-work to develop an updated 1:100 000 scale soil/landform coverage across the region.
Soils are difficult to map at this broad scale because of their diversity. Even in relatively small areas, a number of soils may occur which relate to differences in topography and landscape position. Variation in some of the major soil profile properties can also occur within these mapped areas. Any agricultural enterprise should be based on a proper on-site assessment of the soil and landscape.
A number of soil surveys have been completed in this region at varying scales and intensity. However, in some areas very little soil survey has taken place so see the Soil and Land Survey Directory.
