Lameroo Midslope – Loamy Sand over Medium Clay

This site closely relates to an F2a soil type – sandy loam over poorly structured brown clay. This soil type has a thin sandy loam surface layer, with a coarsely structured dispersive brown clay sub surface. The subsurface becomes calcareous with depth.

The soil pH is alkaline at the surface and becomes strongly alkaline with depth. Rooting depth is approximately 60cm. The dense dispersive subsoil reduces root proliferation. Below the 60cm depth, high pH, boron and sodicity limit further root growth. Seedling emergence could be slightly limited with surface soil having a slight tendency to seal and set hard.

Further information on F2 soils can be found on page 184 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 F2a soil type.
