The technology aims to reduce the cost of measuring soil carbon by 90 percent

Agricultural technology company Agrimix says it is on track to deliver a science-backed toolkit that will dramatically reduce the cost of measuring soil carbon by up to 90 percent for landowners.

Agrimix says the technology will enable landowners across the country to access and benefit from the fast-growing carbon credit market, often inaccessible due to the high cost and variable accuracy of current carbon credit technologies. soil carbon measurement.

Working in collaboration with the Queensland University of Technology Professor Peter Grace AND Associate Professor David RowlingsAgrimix is ​​the first company in Australia to commission a large-scale scientific research study into covariance vortex flow tower technology.

Agrimix has received support for the study from Meat & Livestock Australia and livestock regeneration property investment company Packhorse.

For the past 12 months, a network of flux towers across grazing properties in Queensland and NSW have remotely measured the fluxes of carbon and water into and out of plants and soil at a rate of twenty times a second, every day of the year.

This massive amount of high-frequency time series data has enabled the natural processes that drive plant growth and carbon sequestration to be understood in greater detail. The results show that combining this big data with internationally recognized soil carbon models and the latest remote sensing technologies can create a powerful platform that enables farmers to monitor and drive productivity and ESG outcomes in real time, Agrimix said in a statement.

Chief executive Ben Sawley said the company was collaborating with an international team of carbon and soil eddy flux scientists to develop a reliable and trustworthy measurement tool.

“The importance of our flux tower research is staggering because of the quality and expertise of our science team and their partnerships. They are world class,” Mr Sawley said.

The opportunities to increase productivity and carbon sequestration in Australia were huge, based on improved grassland land performance, however the main barriers to landowners realizing carbon credits had been high cost and variable accuracy, he said. .

“Currently the cost to measure soil carbon by drilling soil cores and transporting them to a laboratory for analysis can be more than $30 per hectare, which makes the carbon credit market out of reach for a portion of considerable amount of land owners. We are focused on providing the most accurate, scientifically proven and economical tools for measuring and modeling soil carbon.”

Mr Sawley said other soil carbon measurement systems based on soil testing were expensive and compromised by the high variability of soil carbon in a catchment.

“In contrast, using a well-tested soil carbon model, calibrated and often validated with flux tower data, provides relatively low ongoing operating costs over large areas. We believe that the eddy flux technique and our reference network will be a key component in modeling agricultural systems, enabling landowners to simulate soil carbon and productivity changes under different management practices, before they start their projects.

Flux tower-based technology is being developed and validated by QUT at multiple properties in Queensland and NSW, including Packhorse’s 10,029ha Moolan Downs property.

Tim Samway

Chair of Packhorse Investments Australia Tim Samway said the collaboration with Agrimix and QUT to develop and prove the effectiveness of the flux tower technology was extremely attractive given that Packhorse aims to amass two million hectares of rural pastoral property with strong productivity improvement and carbon capture potential.

“As organizations globally pledge net zero targets, an increasing amount of carbon credit units will be required to offset emissions,” Mr Samway said.

“Soil carbon is a key low-emissions technology, so further development of affordable and accurate technology such as flux towers and soil carbon models will be a game changer.

“But not all approaches to measuring soil carbon changes are created equal, and it is critical that landowners look to scientifically proven and tested methods to maximize their investment in this technology and generate the most accurate information. correct,” he said.

“The carbon credit market is set to grow to US$851 million in 2021, so it’s exciting to be part of developing Australian-led initiatives that enable landowners to participate in and benefit from this fast-growing market .”

Roma (QLD) beef producer John Scott, Allandale, said he believed the new technology would lead to greater uptake of land carbon projects across Australia.

“While many farmers and ranchers want to participate in carbon sequestration projects to maximize their land and help the environment, the barriers are substantial,” Scott said.

“This will enable us to use a reliable measurement tool to realize commercial opportunities on our land while supporting the environment.”
