Moorlands Flat – Loam over Calcrete Rubble

This site closely relates to a B3a soil type – shallow calcareous sandy loam over calcrete. These soil types consist of sandy loam to sandy clay loam with variable calcareous rubble at the surface. This is over rubbly calcrete layer at a shallow depth.

Soils pH is neutral at the surface becoming more alkaline at depth. Rooting depth is limited to approximately 50cm, however there is often few roots below 20cm. The calcrete layer prevents significant root development and higher pH levels below the calcrete inhibit root growth further. Rooting depth will be determined by the extent of the calcrete layer.

Further information on B3 soils can be found on page 122 of The Soils of Southern South Australia, Part 1 or Part 2.

Detailed representative soil profile data is available for more than 1100 locations around South Australia and can be accessed through Nature Maps, with a handy guide for using data sheets also available. A localised soil characterisation site data sheet provides indicative chemical analysis of a B3a soil type.
