C	140 – 190 cm	Reddish yellow (7.5YR6/8) sand; single grained; loose, moderately moist.

Management Considerations:

Plant Available Water Capacity (PAWC) is low for sandy soils such as these. The soils are, however, well drained.
These strongly acidic sandy soils have a very low nutrient holding capacity and are considered infertile – being naturally deficient in nitrogen, phosphorus, sulphur and potassium. Nitrate and sulphate are readily removed by leaching. Deficiencies of trace elements such as copper, zinc and molybdenum are likely to occur. The trace element boron (B) leaches rapidly through acid sandy soils and deficiencies are also likely to occur.

Notes:

Roughly fits into Gormandale, but has a coloured A3; no coffee rock but iron cemented sand concretions. No samples taken.
