“It’s a symbiotic relationship — in return for providing the host plant with nutrients and water, the fungal microbes get carbon as a food,” Dr Singh said.
“Atmospheric carbon fixed by the plant flows into the soil via fluids released by the roots, increasing the soil carbon rather than removing it.
“More carbon means more grain yield, which is why it’s exciting for me because we’re doing meaningful research.
“Building carbon in the soil improves the soil structure, increases the water content of the soil and nutrient availability and capture.”
Loam Bio has been developing the inoculants for more than four years.
Company researcher Neeraj Purushotham said the results in the first year of trials at Gatton in Queensland were encouraging.
“What we are looking at with our UQ collaboration is to understand more deeply how our inoculant works and also understand how stable carbon is built, because that is what stays in the soil,” Dr Purushotham said.
“By increasing the amount of carbon sequestered, you’re helping the farmer because the healthier the soil, the less fertiliser you need.
“That would mean reducing the use of fertilisers while generating the same benefit in terms of yield, as well as getting carbon inside the soil.”
Dr Singh said the results warranted further investigation.
“Our findings suggest the endophytes have potentially beneficial impacts on crop growth, yield and play a role in altering soil organic matter,” Dr Singh said.
The research was published by Scientific Reports.
