Map Unit Descriptions
Map units have been described on the basis of landform patterns or landscapes which are characterised by different and particular collections or associations of soils.
Each mapping unit has a dominant soil or soils. Where on particular soil is dominant it covers >50% (which has been arbitrarily set) of the actual area within the given landscape. If two more soils are co-dominant then no single soil occupies >50% of the area, but together they occupy most of the total area. Any of the co-dominant soils may be dominant locally within the particular mapping unit. Where a soil is sub-dominant, its occurrence is described as being common on an areal basis (arbitrarily set at 10-20%). Soils which are described as being only of minor occurrence together occupy less than than 10% (and sometimes considerably less than 1-%) of the area within a mapping unit.

Map Unit 1
Classification Code: BbA,BaA - S - PLA
Co-dominant Soils | Minor Soils | Landform Element | Landform Pattern |
BbA,BaA | | S | PLA |
Soil Distribution:
These soils have been formed on outwash deposits of the Grampians and occupy the gently undulating plains at the base of the steeper mountain slopes. The soils are very similar apart from surface textures which range from loamy sand to fine sandy loam and the degree of development of hardsetting surfaces, i.e. there is no development in the BbA soils and only weak development in the soils of subclass BaA.
Map Unit 2
Classification Code: EaK,EcK - SWP - ALP
Co-dominant Soils | Minor Soils | Landform Element | Landform Pattern |
EaK,EcK | EaA | SWP | ALP |
Soil Distribution:
The grey clays, Eck, tend to be the dominant soils of the smaller swamps and depressions which occur on the lava plains. On the other hand the black clay soils, Eak, are commonly found in the swamps and depressions associated with stony rise landscapes and the larger alluvial plains with cracking clay soils. The soils of subclass EaA are occasionally found in swamps and depressions. Due to the map scale only the larger swamps and depressions have been delineated and either the element only is mapped or the element is part of an alluvial plain landform pattern.
Map Unit 3
Classification Code: AaK,AaN,AbKps - S - LAV
Co-dominant Soils | Sub-dominant Soils | Landform Element | Landform Pattern |
AaK,AaN,AbKps | AbK,AbKp EcK,AiNd,DbKd | S SWP | LAV |
Soil Distribution:
These mainly alkaline soils occur on the gently undulating plains in the Willaura area. The conspicuously bleached soils, class Aa, tend to occur on the broad flat crests and other level areas, while the soils with sporadically bleached subsurfaces, class Ab, tend to occur on slopes. Sporadically bleached soils with deep surfaces (AbK and AbKp) are not as widespread as those with shallow surfaces (AbKps). Numerous grey clay (EcK) swamps and depressions are scattered throughout this map unit. Occasionally red or brown soils (AiNd or DbKd) may be found on banks surrounding .these swamps.
Map Unit 4
Classification Code: AaK,AaN,AbKps - HSL - LAV
Co-dominant Soils | Sub-dominant Soils | Landform Element | Landform Pattern |
AaK,AaN,Abkps | AbK,AbKp EcK,AiNd,DbKd | HSL SWP | LAV |
Soil Distribution:
The soils of this unit, which occur to the east of Willaura, consist of conspicuously bleached alkaline and neutral soils (AaK and AaN) in association with alkaline, sporadically bleached soils (AbKps) on the rises and grey clays (EcK) in the numerous swamps and depressions between the rises. Sporadic bleached soils with a shallow surface are more common than those with a deep surface (AbK and AbKp). Red or brown soils (AiNd or DbKd) may occur on the banks bordering the clay depressions. These banks tend to be the best yielding areas, whereas the neutral soils (AaN) are more easily managed and higher yielding than the alkaline soils. Some rises may have basalt boulders and stones scattered on their surface.

Black duplex soils (AhA) and shallow black uniform clay soils (EaKf) occur on the slopes above the level of the basalt parent material of the adjoining plains. Black (EaK) and grey (EcK) clay soils are commonly found on terraces and backplains, while there are minor occurrences of shallow brown uniform clays (EbKf) on limestone valley walls and acidic mottled-yellow duplex soils (BcAph) on fan deposits particularly in the valleys to the south of Cobden.

Soil Distribution:
The alkaline mottled-yellow duplex soils of class Ab are the dominant soils on the gently undulating basalt plains of this unit. On the gentler rises, which generally lack any surface stones or boulders, the soils have mainly sporadic bleached subsurface horizons (AbK) although those with a conspicuously bleached subsurface horizon (AaK) may also occur but are less common. Although the shallow phases (AbKs and AbKps) of subclass AbK occur throughout the unit they are more commonly found on the steeper rises with scattered surface boulders and stones. The sub-dominant soils of these stonier rises are AaK and neutral (AgN) or alkaline (AgK) mottled-black duplex soils. On the rises with many surface stones and boulders, which are mainly concentrated on upper slopes and crests, the soils are dominantly the shallow phase (AbKs) of subclass AbK and shallow friable loamy soils (FaA). Cracking grey clays (EcK) occur on the flats between the steeper rises and in the numerous swamps and depressions that are scattered throughout the unit. Gilgai patches commonly occur on these plains with the dominant soils of both the mounds and depressions being AbK,AbKs or AbKps. In the Hamilton area around Lake Linlithgow, black clay soils (EaN) occur on some banks and are highly prized because of their productivity. There are also minor occurrences of neutral soils (AbN) of class Ab and the phase AbKp which is usually found in the more poorly drained areas, and acidic black duplex soils (AhA).
