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. The Crop Circle research 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 as a researcher, agronomist and consultant to farmers in the northern agricultural region for almost 25 years.


    Highlights of Crop Circles Research include

    • Research and extension into liquid fertiliser equipment and application. This work led to the importation of liquid fertiliser distribution equipment and tow behind liquid fertiliser carts for many famers in the WA grain growing belt.
    • Developing farming systems to combat climate variability using fallow and residual herbicides. This work culminated in a 3 year, 3 location, 3400 plot project funded by the GRDC.
    • Studies of nutrient distribution patterns in the no-till systems for precision furrow placement and interception of residual nutrients.
    • Spot spraying herbicide applications – a multi location project to determine alternative herbicides for effective spot spraying of hard to kill and resistant weeds in summer and winter fallow.
    • Testing manganese Sources for prevention of Split Seed syndrome in Lupinus Angustifolius

    Currently Crop Circle Research is focusing its work on

    • Evaluation of Canola, Wheat and Barley for Plant breeding companies
    • Testing herbicide tolerance and efficacy of new herbicides pre and post registration in a range of cereal, pulse and oilseed crops
    • MRL studies for new chemicals
    • Evaluating new fertiliser products and practices for local and international fertiliser companies
    • General agronomy management strategy trials
    • Agricultural machinery evaluations
    • Horticulture pesticide and fertiliser evaluations.

    Thomo is always looking to improve the profitability of our business and is a leader in agronomic research in the northern ag region. We have enjoyed working with Thomo in the past and to continue this for years to come. 

    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

    I have worked closely with Grant over the past 15 years, he has been instrumental in all aspects of his agronomy advise adding a huge amount of value to our business. His vast knowledge gives me all the confidence I need.
