Improving land management decisions through a better understanding of factors limiting production locations
Aims
  • To identify within paddock variability (subsoil limitations) and its effects on production and recharge.
  • To identify different paddock ‘zones’ and the effect of rainfall (amount and distribution) on production.
Key messages
  • EM38 surveys need to be calibrated through soil testing to identify areas with subsoil constraints.
  • Simulated wheat yields using historical rainfall data demonstrated the effects of soil type and subsoil limitations on potential crop yields and recharge.
  • Variable rate technology for fertiliser could optimise returns for paddocks with subsoil limitations.

Acknowledgments

This project was funded by the National Landcare Program through the North Central Catchment Management Authority. Landholders David and Ian Smith and Ken Hinkley kindly allowed us access to their paddocks and farm records. CSIRO Sustainable Ecosystem researcher Perry Poulton turned himself inside out to provide modelling support to the project team. Harm van Rees and Anne Jackman of CropFacts were critical to the implementation and completion of the project.
