QUA98 (Plot 3)

Site: QUA98 (Plot 3)	Land Unit: Drumborg Basalt Hills
*Aust. Soil Class.:*

General Land Unit Description:
This land unit consists of the undulating rises of Sugarloaf Hill and Sheaok Rise, north of Heywood. The soils consist of Red Dermosols and occasionally Kurosols on the crests and slopes of the rises. On the lower slopes and plains in between the rises, Ferric Brown Chromosols or Dermosols predominate. There are minor occurrences of Black Vertosols in local depressions. Here a two year old Eucalyptus globulus plantation exists on ex-agricultural land

Site Description:

Geology: Quaternary basalt	Landform pattern: Undulating rises to low hills
Position in landscape: Lower slope	Internal drainage: Moderately well drained

Soil Profile Morphology

A1	0-20 cm	Dark brown (10YR3/3) clay loam, moderate granular structure (10-20 mm) parting to moderate granular structure (2-5 mm), very weak consistence when moderately moist, few medium ferruginous nodules, common medium roots. Abrupt and smooth transition to:
	Subsoil
B21	20-60 cm	Yellowish brown (10YR5/6) with common coarse distinct red (2.5YR4/6) mottles, light clay, moderate polyhedral structure (20-50 mm) parting to moderate polyhedral structure (5-10 mm), weak consistence when moderately moist, few medium ferruginous nodules, few fine macropores, areal porosity 0.3%, common very fine roots. Diffuse and smooth transition to:
B22	60-100 cm	Yellowish brown (10YR5/6) with many coarse distinct red (2.5YR4/6) mottles, light clay, moderate polyhedral structure (20-50 mm) parting to moderate polyhedral structure (5-10 mm), weak consistence when moderately moist, few medium ferruginous nodules, few fine macropores, areal porosity 0.3%, few very fine roots. Gradual and smooth transition to:
B23	100-150 cm	Red (2.5YR4/6) with many coarse prominent light yellowish brown (10YR6/4) mottles, light clay, strong polyhedral structure (20-50 mm) parting to strong polyhedral structure (5-10 mm), firm consistence when moderately moist, few medium ferruginous nodules, few fine macropores, areal porosity 0.3%, few very fine roots.
	150-400 cm	Medium clays, a little harder with depth but no impeding layer to roots, decomposing rock between 350-400 cm, and may become impeding to roots, live roots found at 350-400 cm.

Notes: few large macropores below 70 cm due to worm activity.
