Productive soils, healthy climate
We are farmers and scientists transforming agriculture into a Gigaton Carbon Drawdown industry.
At SoilCQuest 2031, we believe soil carbon is the central metric of success for farm resilience, productivity and profitability.
Bringing farmers & scientists together
Soil is our most important natural carbon sink
Soil plays a vital role in the global carbon cycle, storing around twice the amount of carbon than the atmosphere and three times that of vegetation. Small percentage changes in the soil organic carbon pool can significantly affect the global carbon cycle by changing the level of carbon dioxide in the atmosphere.

SoilCQuest presents Carbon Calling
We measure and validate these farming systems and practices through the three lenses of economic viability, soil carbon science and adoptability.
The SoilCQuest team work closely on the ground with landholders, understanding the day-to-day farm culture, the drivers and barriers to innovation.
SoilCQuest has an audacious vision to help double the world’s on-farm carbon stocks by 2031, so that farmers and our planet can thrive.
We have an unapologetically ambitious agenda to fulfil our quest for agricultural soil carbon sequestration, at speed, at scale.
Agriculture can be a Gigaton carbon drawdown industry
Shifting agricultural practices worldwide by 2050 would
For carbon drawdown to help reverse climate change, we need emissions reduction
“Drawdown” is the term used to describe the future point in time when levels of greenhouse gases in the atmosphere stop climbing and start to steadily decline. We cannot reach Drawdown without simultaneously reducing emissions toward zero and supporting nature’s carbon sinks to sequester or drawdown carbon from our atmosphere.
Reaching "Drawdown"
Farmers we work with
Weemabah Trangie, NSW
Broad-acre cropping and grazing Trangie, Western Plains NSW Average rainfall 468mm
The early 2000s saw Mick start work on his father-in-law’s 10,500-acre cropping and grazing farm in Trangie, New South Wales. Uninspired by the model of industrial agriculture and curious to find a different way of doing things, Mick began taking courses to broaden his understanding of regenerative farming and experimenting with innovative practices. Over the last twenty years, Mick has transitioned the farm from purely conventional methods to a more holistic approach.
Mick’s current methods include applying fungal-rich liquid compost extract, cover cropping, and multi-species companion planting. These approaches aim to improve soil health, fertility and water holding capacity, increase resilience to pests and diseases, decrease weed pressure, and reduce reliance on harsh agricultural chemicals.
Canowindra, NSW
Broad-acre cropping,
merino sheep and Illawarra dairy cows
Canowindra, Central NSW
Average rainfall 602mm
Stuart is a fourth-generation farmer on 1400 hectares in Canowindra, NSW. Stuart’s family took ownership of the property in 1888 and has been there ever since. Stuart grows dry-land crops, including wheat, canola, barley and chickpeas, and raises merino sheep and Illawarra dairy cows.
In 2020, Stuart transitioned the family farm to a zero-till approach as a way of helping maintain ground cover. Canowindra experiences a non-seasonal distribution of rainfall, so making the most of the rain available is vital to extending the growing season of his crops. Stuart selects varieties based on their suitability for the rain’s timing, and is currently experimenting with summer cover crops and different companion planting combinations.

Forbes, NSW
Broad-acre cropping and grazing
Forbes, Central West NSW
Average rainfall 426mm
Steve and his wife bought their property 22 years ago and now run a successful farm business with their two sons. They own and lease 3,500ha and grow wheat, barley, canola and occasionally legumes, long-term perennial pastures, and have 4,000 head of merino sheep.
Steve’s background as an Agronomist means he has a thorough understanding of agricultural science and knows that healthy soils are everything. A long-standing focus on improving soil health and structure since the Millennial Drought meant that Steve’s farm continued to be profitable throughout the tough seasons we’ve had since.
Steve does not believe in relying on a perfect year but instead depends on ensuring his farm is resilient enough to withstand unpredictable but inevitable harsh weather events. His approach involves a balanced strategy for managing the land, using groundcover methods and good chemical applications that don’t destroy the soil.
Manildra, NSW
Grant and Carmen, Luke and Belinda, Alex and Kate Manildra, Central West NSW Average rainfall 625mm 1740 Ha (owned/leased/share-farmed)
Wheat, barley, oats, canola, chickpeas, sorghum
Angus cows and Merino 1st cross ewes.
The Wood Family has been in the Manildra district for 20 years, moving from the Blayney area in 2001. Their focus is on improving soil health through zero till and CTF on 9m. A diverse rotation of cash and grazing crops and livestock are integral to the ongoing goal of increasing soil organic carbon and decreasing bulk density. Shifting soil characteristics in that direction will help to bolster the resilience of the overall business.
With a background in Agronomy, Luke and Alex are proactive in trying new ideas and technology to improve their farming system. The Woods family strive to reduce synthetic inputs, particularly fungicides and insecticides, to allow beneficial soil biology to express.

Agriculture has the greatest carbon drawdown potential
Shifting our agricultural practices could sequester the most amount of greenhouse gases globally by 2050, by supporting our natural carbon sinks of soil and vegetation.
Shifting agricultural practices could sequester the most Gigatons of carbon dioxide equivalent by 2050
Our Story
SoilCQuest is a for impact research institute, collaborating with research and industry partners on farm systems innovation and education. Achieving our goals will result in viable, climate smart agriculture and agribusiness resilience.
Founded in 2012 by Guy Webb, Mick Wettenhall and Mark Shortis, SoilCQuest 2031 was established to develop a microbial inoculum from a carbon-capturing fungus discovered in our soils. This melanised endophytic fungus sequesters long lasting soil organic carbon around plant roots. When inoculated onto the roots of crops via a seed dressing, this microbial inoculum draws down atmospheric carbon and is practical and scalable technology for farmers to increase their soil carbon.
In 2019 Guy Webb and Mick Wettenhall raised investment for this technology and formed Loam Bio with Guy Hudson, Tegan Nock and Frank Oly. Loam Bio is a bio-tech startup at the intersection of agriculture, climate change and microbes. Developing these technologies, Loam Bio puts agriculture at the forefront of improving soils and our climate.
SoilCQuest continues as a research institute and a key stakeholder in Loam Bio.
