WebIdentifying WA soils. Western Australia covers a vast area with a wide range of soil types. Many areas of the south-west of the state are characterised by soils with sandy surfaces ranging from deeps sands to sands over clays, and soils dominated by ironstone gravels. Soils in the northern parts of the state, although variable, are often ... WebThe Ultisols are the most highly weathered of the temperate zone soils. They are characterized by a thin or absent A horizon, with a thick, strongly expressed B. The soils are deep and productive if well-managed. The soils are often very red or yellow-red and are the dominant soil of the southeastern U.S. See some ULTISOLS. Oxisols (oxidized)
