GL63

Site: GL63	Land Unit: Condah Basalt
*Aust. Soil Class.:* Ferric, Eutrophic, Yellow CHROMOSOL (confidence level 1)

Soil pit GL63 auger

General Land Unit Description:
The undulating plains and rises of the Condah area mainly consist of Ferric Chromosols. On the lower slopes bleached A2 horizons and mottled subsoils are common. On the broad level crests, gilgai microrelief is common.

Site Description:

Slope: 2%	Geology: Quaternary basalt
Landform pattern: Level to gently undulating plains	Position in landscape: Crest
Internal drainage: Moderately well drained

Soil Profile Morphology
