A unique
collaboration

SoilCQuest 2031 is a unique collaboration of farmers, agricultural and soil scientists, agro-ecologists, agronomists, educators, and business, communication, and extension specialists.

The thread connecting our diverse backgrounds and expertise is a deep respect for the farming profession and the agricultural industry. We understand daily farm life and culture and how it drives decisions and change on the ground.

Our multidisciplinary team of Board Directors, Staff, and Research Committee Members have extensive experience across the agricultural industry, academia, community, and government.

Associate Professor

Richard completed his studies at the University of New England with a focus on plant nutrition and root: soil interactions, and has over 15 years research experience across a diverse range of fields relating to soil physical and chemical fertility, as well as plant function and productivity in both crop and pasture systems.

He has worked on improving non-wetting soils in WA; on root system architecture and nutrient acquisition of crop and pasture species; in ameliorating constrained soils; and more recently in mitigating green house gas emissions from agriculture through the Zero Net Emissions Agriculture Cooperative Research Centre.

Richard is committed to a practical and systems approach to solving problems in agriculture, using strategies that are implementable and realisable by farmers, to improve the sustainability and productivity of farming systems.
