Geology
Neogene (late Tertiary) alluvial sediments. The Tertiary sediments form the oldest ‘terraces’ and outwash fans from the uplands. The soils close to the Eastern Highlands the soil profile often has a gravelly component, but further south the soils are finer textured, with loamy fine sands to fine sandy loams overlying clays.

This early depositional sequence has been strongly dissected over time and sands, probably windblown from the many drainage lines, cover about 10 – 30% of the area. These soils often have organic matter and iron cemented sands in the subsoil, generally from about 70 cm – 1m.

Landform
The Waygara map unit encompasses undulating rises to rolling low hills. In the late Tertiary it is most likely that the area was an alluvial plain but since then this has been dissected and subject to periods of aridity, resulting in areas of deep sand cover. Consequently the map unit may be subdivided into two components.

Original vegetation
Lowland forest.

Soils
Component 1
Most of the soils of the Waygara map unit are texture contrast soils. The surface soils are strongly to moderately acidic and range from dark greyish brown loamy sands to sandy loams generally with a bleached subsurface soil. Brown medium to heavy clays, which are generally strongly to moderately acidic, occur at a variable depth, generally before 50 cm, typically with yellowish brown, grey or strong brown mottles. The sandy surface soils have a low nutrient and water holding capacity where the organic matter levels are low and are also prone to wind erosion; see EG 221, EG 248, EG 249, EG 250, EG 251. Areas of soils with sandy clay loam subsoils may also occur (Newell and Woodruff, 1962); see Site 147 Rees (unpublished).

Component 2
About 10 – 30% of the area is covered by deep sand generally with organic matter and iron cemented sands in the subsoil. In the Newell and Woodruff report (1962) it is called the Tostaree map unit (See EG 220).

Land use
Areas which have been cleared are used for grazing, but most of the uncleared land is public land and subject to forestry or is national park.

Previous maps and reports
A reconnaissance of soil and vegetation was made of an area south of Princes Highway between the Nowa Nowa River and Newmerella comprising about 20 250 ha, as well as a detailed survey of about 450 ha was made by J. W. Newell and B. J. Woodruff in 1962. This report is titled ‘Soils and Vegetation in the Hartland Area’, Soil Survey Report 34, Soils Section, Department of Agriculture.

Management considerations

Whole profile
  • If the soil is under pasture with an effective rooting depth of 70 cm, the plant available water capacity is considered to be low (estimated at 52 mm). Because of the low wilting points throughout the profile, plants will be able to use very light rains when the soil is dry. Due to the low water storage capacity of the soil, plants will suffer water stress unless further rains occur.
Surface (A1 and A2) horizons
  • The soil has a low organic matter content, but there are sufficient coarse roots to hold the soil together.
  • The soils are strongly acidic and, if under pasture, may show a response to lime. Test strips should be first used to evaluate the cost/benefits.
  • The nutrient holding capacity of the soil is very low (based on the sum of the exchangeable basic cations).
  • Potassium levels are deficient and a strong response to potassium fertilizers would be expected if the soils are under pasture.
Subsoil (Bhs) horizon
  • Even though this layer is cemented, it is sufficiently porous and well drained.

Management considerations

Whole Profile
  • The plant available water capacity of the soil is considered to be low (estimated at 54 mm) for the top 50 cm of the soil profile.
  • The dense and coarsely structured subsoil is likely to restrict root movement.
Surface (A) Horizons
  • The sand surface horizons are very well draining but have a low water storage capacity. The low wilting points (i.e. 5.7 and 3.0) indicate plants will be able to utilise light rains falling on dry soil. However, due to the low water storage capacity, plants will soon suffer moisture stress unless further rain occurs. Organic matter is an important source of nutrient holding capacity as well as enhancing water holding capacity in sandy soils.
  • The sandy surface soil will also be prone to wind erosion if plant cover is removed where blow-outs can occur.
  • The surface horizons have a moderate inherent fertility (based on the sum of the exchangeable cations).
  • The surface soil is quite high in potassium and no response to potassium fertilisers would be expected.
Subsoil (B) Horizon
  • The dense and coarsely structured upper (B21) subsoil is sodic. This will restrict the downward movement of plant roots and water. The temporary build up of water on top of this less permeable layer may be beneficial for deeper-rooted plants as it prevents deep drainage of water away from plant roots.
  • Sodic subsoils are typically moderately to strongly dispersive, but here are only slightly dispersive, mainly due to the high exchangeable aluminium.
  • The upper (B21) subsoil has a relatively moderate inherent fertility throughout (based on the sum of the exchangeable calcium, magnesium and potassium cations). The cations are dominated by exchangeable magnesium which may create nutrient imbalances.
  • The level of soluble salts is low.

Management considerations
  • The subsoil has low calcium and a low calcium to magnesium ratio. Calcium deficiencies may occur as a result.
  • The soil profile is strongly acid throughout. The availability of some elements (eg copper and molybdenum) may be low as a result. Aluminium toxicity can be a problem in strongly acid soils and the level here is likely to affect phosphorus availability. The use of test strips to see whether the addition of lime is going to be economical is recommended if the soil is to be used for pasture.
  • Potassium is low and deficient and a response to potassium fertilizer would be expected.
