Land zone 11
Short description: metamorphic rocks General term: hills and lowlands on metamorphic rocks Metamorphosed rocks, forming ranges, hills and lowlands. Primarily lower Permian and older sedimentary formations which are generally moderately to strongly deformed. Includes low- to high-grade and contact metamorphics such as phyllites, slates, gneisses of indeterminate origin and serpentinite, and interbedded volcanics. Soils are mainly shallow, gravelly Rudosols and Tenosols, with Sodosols and Chromosols on lower slopes and gently undulating areas. Soils are typically of low to moderate fertility. (Queensland Government, 2016)

Land zone 3
Short description: recent Quaternary alluvial systems General term: alluvial river and creek flats Recent Quaternary alluvial systems, including closed depressions, paleo-estuarine deposits currently under freshwater influence, inland lakes and associated wave built lunettes. Excludes colluvial deposits such as talus slopes and pediments. Includes a diverse range of soils, predominantly Vertosols and Sodosols; also with Dermosols, Kurosols, Chromosols, Kandosols, Tenosols, Rudosols and Hydrosols; and Organosols in high rainfall areas. (Queensland Government, 2016)
Chromosols and Kurosols
Both these soil orders are texturecontrast soils. Kurosols are strongly acid (pH below 5.5) whereas Chromosols are not. Extensive areas of Chromosols are in the Western Downs and the Maranoa districts—west of the Great Dividing Range. Kurosols occur along the coast, mainly in southern Queensland. (Queensland Government, 2016)
Rudosols, Tenosols and Podosols
These soils orders generally have a low fertility and low water-holding capacity. Rudosols and Tenosols are poorly developed but widespread and can be shallow and stony. The most extensive areas of these soils are inland from Cairns. Podosols occur in the more humid coastal regions including areas such as Fraser Island and Shelburne Bay. Podosols occupy less than 1% of the state. (Queensland Government, 2016)
Vertosols
Vertosols are the most common soil in Queensland—characteristics include: • brown, grey or black soils which crack open when dry • they commonly form hummocky relief called gilgai • very high-soil fertility—ability to supply plant nutrients • large water-holding capacity. These soils are the cracking clay soils of the Darling Downs and Central Highlands. A large belt of grey and brown Vertosols also run from the New South Wales border to Charters Towers—corresponding with Brigalow forests. (Queensland Government, 2016)
Ferrosols and Dermosols
Ferrosols are well-drained soils with red or yellow-brown colour and have clay-loam to clay textures. This soil type is usually associated with previous volcanic activity and is mainly located along the Great Dividing Range. Large areas of these soils occur around Kingaroy and Atherton where they are used for intensive crop production. Dermosols are red, brown, yellow, grey or black and have loam to clay textures. This type of soil covers the higher-rainfall coastal and sub-coastal regions. Important areas of these soils are the Burdekin delta and the Lockyer and Fassifern valleys. (Queensland Government, 2016)
Sodosols
Sodosols are texture-contrast soils with impermeable subsoils due to the concentration of sodium. These soils occupy a large area of inland Queensland. Generally Sodosols have a low-nutrient status and are very vulnerable to erosion and dryland salinity when vegetation is removed. (Queensland Government, 2016)

Bore Reports
To gain complete accuracy of soil composition, boring should be carried out in the site area. This will be able to provide the information required to ensure the most successful selection of planting. The immediate and ongoing success of the plants planted is critical to the strategy and so should in know way be overlooked. For now, the nearest boring done within the same land zone type can give and indication of the soil makeup and inform initial plant selection. Bore number RN 181363 report result can be seen in Figure 10.
