Loam Bio and leading researchers from the Western Sydney University have announced results from a pioneering research collaboration demonstrating how fungi can increase soil carbon stocks and their stability.
This research demonstrates Loam’s fungi has the potential to increase carbon sequestration in soil and enhance the stability of soil carbon.
Not all fungi are created equal – some fungal species were shown to be better than others at improving plant performance and stabilising soil carbon.
At harvest, specific native fungal seed treatments in the study showed:
Importantly, increasing the stability of soil carbon indicates that sequestered carbon is less likely to be lost in future.
This innovative study was performed by world-class researchers Dr Emiko K Stuart, Dr Laura Castañeda-Gómez, Professor Jeff R. Powell, Dr Wolfram Buss from the Australian National University, and led by Dr Yolima Carrillo from the Western Sydney University’s Hawkesbury Institute for the Environment.
This evidence native fungi can sequester carbon in soil unlocks opportunities for more farmers to improve soil health and earn carbon credits.
Since 2019, Loam has been developing products which address the problem of too much carbon in the atmosphere and not enough in soils, where it is essential for soil health and agricultural productivity.
By independently characterising Loam’s fungal library, researchers at WSU have demonstrated the potential of non-mycorrhizal fungi for carbon sequestration.
“Combining multiple approaches to assess soil carbon responses, its origin, dynamics and fate in controlled experimental conditions was a powerful strategy to detect and understand the impact of the different fungal species and we are looking forward to continuing to investigate the mechanisms that drive the positive responses observed,” Dr Carrillo said.
“In our pursuit of enhancing stable soil carbon sequestration, results surrounding resistant carbon pools have emerged as critical findings,” Dr Jones added.
“These pools serve as a vital buffer against soil carbon loss and play a key role in placing our cropping systems and the broader Australian agricultural industry at the forefront of climate change mitigation.”
This study reinforced Loam Bio’s capacity to harness the potential of microbes to address climate change and deliver greater outcomes for farmers.
Dr Carrillo, Dr Stuart and Prof Powell are excited to continue researching the role of fungi in soil carbon cycling.
For farmers, the benefits are substantial.
Stable soil carbon translates to improved plant growth, productive soils and a more sustainable cropping system.
By harnessing the power of fungi to enhance soil carbon storage, this collaboration strives to equip farmers with knowledge and strategies to sequester soil carbon, while optimising their yields and increasing the sustainability of their operation.
