The 2025 SPAA Precision Ag Expo was held on 27 March 2025 in Wallaroo. This conference-style event brings together growers, researchers, agronomists, precision ag (PA) consultants and the education sector. The 2025 event explored the latest applications of PA developments in relation to soils, seeding, satellites, sensors and other tech, as well as spraying (in terms of targeted weed management).

Summary
South Australian crops can be severely impacted by poor and variable growing conditions, which includes low-fertility soils. Crop plants possess strong instincts to reduce grain number due to variable growing conditions or reduced fertiliser. This is a major contributor to the yield gap in SA. This project seeks to help close this yield gap through the import and testing of new genetic material that makes barley less responsive to environmental conditions.

Latest Research Projects
SA Mallee regional internship in farming systems and applied grains research and extension (MSF7124)
The intern will gain hands-on experience of regional research and develop an understanding of the challenges of farming in a low rainfall zone. Through mentoring by an MSF farmer member, the intern will gain insight into the practicalities of farming in the Mallee, its challenges and rewards. The intern will work on projects that have been prioritised by MSF and local farmers, such as crop rotations, amelioration, soil variability, weed management, soil moisture and risk management and business development. This project was funded through and out-of-session application in October 2024 and is a co-investment, with the SA Drought Hub providing 50% of the total funding.
Mixed farming intern – Limestone Coast (MFM1125)
This project will employ an intern to build the human capacity of the grain-livestock industry, particularly in the areas of research, development and extension and drought resilience in the Limestone Coast (south east SA). This project is a co-investment, with the SA Drought Hub providing 50% of the total funding.
