PYROAG’s Wood Vinegar is leading the Australian charge to combat rising fertiliser costs and amplify premium regenerative farming methods.
The Australian-owned company is urging farmers to embrace the next generation of sustainable farming practices, as well as stripping their fertiliser costs significantly.
Pyroligenous acid (wood vinegar) is made by heating organic biomass material such as recycled wood chips in an oxygen-reduced environment.
The output gas is cooled into a liquid, which is separated and refined into wood vinegar.
A 2018 study between PyroAg and Newcastle University found wood vinegar improved soil’s biological health by enhancing the beneficial plant-growth-promoting bacteria.
According to the study, the application of PA in lower concentrations to soils enhanced microbial diversity and the abundance of beneficial microbes such as plant-growth-promoting bacteria in soil.
“The organic by-products from agriculture, which otherwise go as wastes in the environment, are now recycled and used effectively to increase agricultural production,” Newcastle University CRC CARE program leader Professor Megh Mallavarapu said.
“The researchers at the Global Centre for Environmental Remediation, University of Newcastle, conducted laboratory investigations to check for any potential impacts of Pyroligneous acid product (PyroAg) on aquatic and terrestrial biota in soil.
“Aquatic toxicity assays (alga, water-flea and duck weed) were included in this study in order to check the offsite impact of PA.
“The results suggest the PA is unlikely to pose risk to the aquatic biota at environmentally relevant concentrations.
“Whereas, in earthworms, the lower concentrations of PA promoted the cocoon and the juvenile production.”
PyroAg CEO John Mellowes said it was imperative the company complete the four-year study to present a case to Australian farmers.
“Through years of testing on a global and local scale, the evidence is promising,” he said.
“By increasing bacterial quantities and inhibiting actinomycetes, wood vinegar plays a role in dramatically changing the sustainability and stability of the soil ecosystem.
“The key is for farmers to look for alternative suppliers of bio-stimulants including local Australian products such as PyroAg Wood Vinegar.
“PyroAg is continuing to invest in research, with a new federal government grant funded project looking at yield increases through PyroAg applications.”
