Lowaldie Midslope – Sandy Loam over Clay

This site closely relates to a C1 soil type – gradational red sandy loam. This soil type has a sandy loam surface layer, becoming more clayey and calcareous at a shallow depth. This grades to a red sandy clay loam with Class III carbonates.

The soil pH is alkaline at the surface and becomes strongly alkaline with depth. Rooting depth is approximately 70cm, but with few roots below 50cm. The level of rubble in the profile limits its water holding capacity. Soil depth below 70cm is higher in pH, salinity, sodicity and boron levels and limits root growth. Seedling emergence can be affected by sandier water repellent incidences.

Further information on and C1 soils can be found on page 140 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 C1 soil type.
