KAN98 (Plot 1)

Site: KAN98 (Plot 1)	Land Unit: Warrabkook Basalts
*Aust. Soil Class.:*

General Land Unit Description:
This land unit consists of gently undulating basalt plains in the Macarthur area. In some drainage lines, the basalt has been dissected sufficiently to expose the underlying sediments. The soils on the basalt plains are commonly Brown Kurosols or Chormosols, intermixed with Sodosols, particularly on the lower slopes and drainage depressions. This site has two year old Eucalyptus globulus in a plantation on ex-agricultural land.

Geology: Quaternary basalt	Landform pattern: Level plain

Soil Profile Morphology

A1	0-22 cm	Very dark grey (10YR3/1) loamy sand, single grain structure, loose consistence when wet, common medium roots. Gradual and smooth transition to:
A2	22-50 cm	Dark greyish brown (10YR4/2) loamy sand, single grain structure, loose consistence when wet, few medium roots. Clear and smooth transition to:
A3	50-55 cm	Brown (10YR5/3) clayey sand, weak granular structure (10-20 mm), very weak consistence when wet, common medium ferruginous nodules, few medium roots. Abrupt and smooth transition to:
	Subsoil
B21	55-90 cm	Grey (10YR5/1) with common coarse distinct reddish yellow (7.5YR6/8) and red (2.5YR4/8) mottles, light medium clay, strong polyhedral structure structure (20-50 mm) parting to strong granular structure (5-10 mm), weak consistence when moderately moist, common very fine macropores, areal porosity 0.08%, few very fine roots. Diffuse and smooth transition to:
B22	90-150 cm	Brown (10YR7/1) with common very coarse prominent brownish yellow (10YR6/6) and red (2.5YR4/8) mottles, medium clay, strong vertical lenticular structure (50-100 mm) parting to strong granular structure (10-20 mm), weak consistence when moderately moist, common very fine macropores, areal porosity 0.05%, few very fine roots.
	150-300 cm	Clays with the odd sand pocket, similar to above, live roots found growing in old root channels.
	300-400 cm	Decomposing vesicular basalt (soft, well aerated) in a grey/yellow brown clay matrix, remnant roots observed, no root impeding layer.
