Waikerie Midslope – Sandy Loam over Loamy Clay/Calcrete (Maggea)

This site closely relates to an A4/C1 soil type – gradational red sandy loam. This soil type has a sandy loam surface becoming more clayey and calcareous at shallow depth. It grades to a red sandy clay loam with Class III carbonates.

The soil pH is alkaline at the surface and strongly alkaline with depth. Rooting depth is approximately 70cm, but very few roots extend below 50cm. Rubble reduces the wather holding capacity of the soil. High pH, salinity, sodicity and boron from 70cm limit root growth. Seedling emergence can be limited by sandier types, which are water repellent.

Further information on A4/C1 soils can be found on page 104 & 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 an A4/C1 soil type.
