About Us

Agronomy. Research. Consulting. 

Crop Circle Consulting and Research is an independent research agronomy firm, based in Geraldton, the central hub of the northern agricultural region of Western Australia.

Grant Thompson and his team combine attention to detail and rigorous methodology to test new plant breeding material, fertilisers and pesticide chemistry in a variable Mediterranean climate.

The region is a world leader in lupin (lupinus angustifolius) production, as well as producing quality hard and noodle wheats, malting and feed barley, canola, chickpeas, oats, triticale and grazing pastures.

The region ranges from light textured grey sandy soils, through to deep loamy sand yellow sandplain soils, acidic wodjil soils, red loamy sand soils through to heavy red clay loam soils overlying limestone.

Grant Thompson

Director and Agronomist

Director and agronomist Grant Thompson has been working alongside and consulting to farmers in the area for many years.  Grant grew up working alongside his parents on a 29000 hectare (72000 acre) grain and livestock property in Mullewa. After completing an honours degree in Agricutural Science at the University of Western Australia, majoring in soil science and plant nutrition, Grant worked on farms in the UK before returning home to work as a researcher for Wesfarmers CSBP Ltd, in their Field Research Unit.  A 2 year stint as a regional and fee for service agronomist for IAMA led to a contractors postion at Wesfarmers Dalgety and then Landmark in Geraldton, whilst working as a private consultant agronomist to growers in the midwest.


Grant has been working as an agronomist and consultant to farmers in the northern agricultural region for almost 20 years. As a contractor to national leading Agribusiness LANDMARK, he provides agronomy support to their customers and is also involved in a comprehensive research program, as well as liaising with a team of hundreds of agronomists throughout Australia.  With a vision to think outside the square and develop new ideas, coupled with a keen interest in the development of liquid fertiliser practices in the region, Grant took the opportunity to travel to Canada to meet with liquid fertiliser and machinery companies and attend the SIMPLOT liquid fertiliser conference in Regina. This provided an opportunity to visit farmers and agronomists in the fluid fertiliser arena, and led to the imporation of liquid fertiliser distribution equipment and tow behind liquid fertiliser carts for many famers in the WA grain growing belt. 

In recent times,  our R&D efforts have been focused on creating new farming systems and strategies to  combat climate variability,  control exotic summer and winter weeds, storing and managing soil water and increasing farm productivity and profitability  using fallow systems, residual herbicides and herbicide tolerant crops. This work culminated in a 3 year, 3 location, 3400 plot project funded by the GRDC, utilizing R&D contractors and partners. 

As optimists, we at Crop Circle Consulting believe that the future of agriculture is a bright one.  Adopting new technology, managing climate variability, improving our farming environment and our carbon footprint will be the key to making agriculture sustainable and profitable into the future.

Tim Critch, Wyalong Farm, Tenindewa

Waringa Farming has been using Grant Thompson from Crop Circle Consulting since 2009. Grant has played a big part in our business by providing independent agronomic consulting to Waringa.  Grant works with us to provide the agronomic knowledge, new ideas and a second opinion and this has been important to our business to ensure we make the right agronomic decisions. 

As Grant has been brought up in a low rainfall and large broad acre farming environment we believe this experience together with his agronomic accumen combined gives him great knowledge to advise and assist us to make the right decision.

John Warr, Waringa Farming Co, Yuna
