GL77

Location: Greenwald

Australian Soil Classification: Ferric, Eutrophic, Brown, CHROMOSOL (confidence level 1)
General Landscape Description: Undulating rises
Site Description: Upper slope
Land Unit: Gorae Basalt
Geology: Quaternary basalt

General Land Unit Description: This land unit has a variety of soil types occurring over a short distance. Ferrosols and Black Chromosols are found is association with the more dominant Ferric Brown Chromosols. The Brown Chromosols have been used to represent this area as they are deemed to be the major soil type, and due to restrictions of scale the other soil types have not been mapped as individual units. It must be noted however, that the better drained soils (Red Ferrosols / Dermosols) have a higher capability of supporting a range of land uses (e.g. viticulture) due to their favourable physical and chemical properties.


Soil Profile Morphology

Surface Soil

A110-10 cmDark brown (7.5YR3/3) loamy sand, apedal to weak structure, weak consistence when dry, many ferromanginferous nodules and a few medium subrounded basalt pebbles (2-10 mm), pH 6.3; transition to:


A1210-40 cmDark brown (7.5YR3/3) sandy loam, weak polyhedral structure (2-10 mm), ferromangiferous nodules are abundant, pH 6.1; transition to:


Subsoil


B240-70 cmStrong brown (7.5YR4/6) sandy clay, many distinct red mottles, weak subangular blocky structure (5-10 mm), very firm consistence when dry, ferromangaiferous nodules and angular basalt fragments are abundant, pH 6.2.




Key profile features:
  • Strong texture contrast between topsoil and subsoil
  • Mottled subsoil
  • Ferromangiferous nodules and coarse fragments are abundant throughout
