Our groundbreaking seed inoculum that uses wheat roots to store increased soil carbon stably in cropping soils

A tailored solution for your wheat crop
CarbonBuilder Wheat, providing productivity and sustainability outcomes with ease of delivery


CarbonBuilder Wheat is delivered as a seed inoculum, applied at time of planting. Simple, economical, impactful.
What are the results?
CarbonBuilder Wheat was extensively tested across Australia during our 2023 small plot field trials.
Its performance was assessed independently by Kalyx during 5 small plot trials across 5 sites.
Across these sites we observed an average of 3.2% increase in total soil carbon and a 3.6% increase in grain yield, when the crop was treated with CarbonBuilder Wheat compared to the control.
We saw a win-rate of 80% across locations for both carbon build and grain yield.
What is CarbonBuilder Wheat?
Building stable soil carbon in your wheat crop
CarbonBuilder Wheat is one of our groundbreaking microbial products that supports wheat’s natural ability to draw down carbon into cropping soils. CarbonBuilder Wheat is an endophytic fungi applied as a seed dressing, and is compatible with most fungicidal seed treatments in Australia.
CarbonBuilder provides an important tool for growers looking to participate in soil carbon projects and increase crop productivity.

How does it work?
CarbonBuilder Wheat has been developed and extensively tested in Australian cropping soils
The beneficial fungi in CarbonBuilder Wheat is a dark septate ascomycetous fungi belonging to the order Chaetosphaeriales.
The members of this genus have been previously reported as saprophytes, commonly found in soil and plant litter from both terrestrial and freshwater habitats.
Species from this genus have also been reported as non-pathogenic root endophytes, which colonise the inter/intracellular spaces of the roots.
