Sandy Soils & Soil Modification
The Ag Bureau of SA and branches of across the State have undertaken numerous projects on this issue.
This has culminated in the collation of a best practice manual.
Current projects relating to sandy soils include:
- The 20:20 Carbon Challenge: increasing soil organic carbon of sandy soils - funded by Caring for our Country and to be completed in 2013.
This project has already: undertaken in-depth sampling of 3 sites; selected 6 demonstration sites and collected baseline data from those sites; completed a soil C audit for 42 sites; established a database of modified soils on Eyre Peninsula and in the South East; and seen the commencement of a PhD student undertaking associated research.
- Reducing erosion and improving soil health by modification of sandy soils - funded by the State Government Sustainable Dryland Agriculture Initiative.
This project has already produced a publication and other articles and presentations. A workshop is planned for June/July 2012, spring field day activities and a state compendium report.
The State NRM Program has also funded projects carried out by the Karoonda and Southern Mallee branches.
Through these projects, yield data and root development impacts have been monitored to examine the benefits of the various methods of modification of sandy soils.
