The Central Queensland Grower Solutions (CQGS) project illustrates the power of precision agriculture (PA) technologies in transforming grain farming. By collaborating with regional growers, the project integrates advanced tools to maximise efficiency, boost yields, and cut costs.
Driving farm productivity
Using PA technologies has transformed the operations of local farms.
A range of case studies showcases how PA technology is being successfully implemented in local farming systems and delivering impressive results.
Here’s what you need to know:
- Every grower increased productivity and profitability through precision technology.
- Most growers estimated a return on investment within a few years.
- Reduced expenses on chemicals and seeds made a noticeable impact on margins.
Results varied depending on factors like paddock conditions and technology choices, but identifying tools tailored to specific needs was key to every success story. Through tailored application and targeted approaches, precision planting is directly improving yields, reducing costs, and contributing to the development of a more competitive grains industry.
Cutting weed control costs
Weed control is one of the largest expenses for growers. Optical spot-spraying cameras, section-control spray rigs, and similar precision tools are helping growers dramatically reduce chemical use and overcome herbicide resistance.
Game-changing weed management tools
- WeediT Technology: Reduced chemical use by 82–94%, translating to $14–16/ha in savings for 5 growers.
- Weedseeker 2 Technology: In one case, retrofitting this tool onto a self-propelled sprayer resulted in 97% chemical savings and $11.50/ha in savings during the first spray.
- Section Control Sprayers: Precision control to avoid waste, resulting in 3% less chemical use for one grower.
Ground-following booms have proven most effective in flat paddocks but face challenges with obstacles, while suspended booms perform better in undulating terrain.
These technologies are particularly valuable in drought-affected areas, where preserving moisture and combating herbicide resistance are critical. Together, they offer practical and scalable weed management solutions for Queensland growers.
Precision tools for planting
In tough growing conditions, every decision matters, especially when it comes to planting. Ensuring precise seed placement can help you reduce waste, conserve resources, and boost your farm's profitability.
Farmers are reporting:
- seed savings: 3 Central Queensland growers cut seed use by 5–25%
- lower costs: Sorghum growers saved $2–5/ha, while mungbean growers saved $10/ha
- smart section control: One grower slashed seed costs by 24%.
These planting technologies improve crop performance and profitability, supporting sustainable production practices in the long term.

Why this matters for you and Queensland
The advances made by these growers are just the beginning. By investing in PA technologies, you’re unlocking more than just higher yields and lower costs; you’re also contributing to the long-term sustainability of Queensland's agricultural sector.
The CQGS project, brought to life through a partnership between the Grains Research and Development Corporation (GRDC) and the Queensland Government, is driving this wave of innovation. With support from leading producers, it's positioning Queensland as a leader in agricultural innovation.
