Geology and Geomorphology

The soil pit sites shown on this image have been characterised in association with the Birchip Cropping Group (external link). A series of soil pits were described during 2000 and 2002 as part of the Overcoming Rootzone Constraints (ORZC) project funded by the State Government’s Science, Technology and Innovation (STI) Initiative. Other soil pits were described in late 1993 (as part of a National Landcare Program funded project) and have also been included here. The more recent soil pits have been characterised as part of the 'Healthy Soils' project being run by DPI in association with BCG.

Healthy Soils

These soil pits have been selected as example soil profiles for major soil types in the Birchip area. There is only limited information available on soil types in this area and only general Land System maps exist at a broad scale of 1:250 000. Therefore, these pit sites should be used as a guide only to some of the soils. It is not possible to give an estimate as to how representative these sites are of major soil types across the region.

We wish to thank Ian and Warrick McClelland, John Ferrier, John Jones, Rex Barbary and Neil Davis for organising the site selection and soil pit excavation in 1993. A number of landholders must be thanked for allowing soil pits to be excavated during 2000 and 2002 including Leigh and Julie Weir, Ian and David Smith, Glenys Rickard, Alistair and Marcus Ferrier, Graeme and Jeni McLean, Roger, Dianne and Lincoln Lehmann, Eddie and Francis Lee.

Tony Fay (DPI, Birchip) must be thanked for organising a number of the 2002 pit sites.
