METHODS used in organic farming will be "unavoidable" if Professor Ross Garnaut's recommendations are followed, according to organic farming groups.
Australian Carbon Farmers Coalition founder Michael Kiely said carbon uptake in soil could be improved through organic methods.
"Non-organic farmers can capture large amounts of carbon, but you can 'turbo-charge' carbon uptake in soil if you protect the microbiological community below who manufacture it," Mr Kiely said.
"Any use of toxic substances - such as synthetic farm fertilisers, pesticides and insecticides - disrupts this."
Mr Kiely said many farmers were not aware they had billions of creatures working for them in their soil.
Biological Farmers Australia Standards Chairman Dr Andrew Monk said organic producers were looking to employ methods to improve their soil's long-term carbon capture potential.
"Organic farming's . . . design and implementation, organic works with and not against nature - and is only just beginning to get the environmental recognition it deserves."
Dr Monk said there may be opportunity for certified organic farmers to take advantage of the report's focus on carbon plantations and increased tree plantings, given that under the Australian Organic Standard, producers are required to set aside a minimum of 5 per cent of their property for regionally appropriate native land preservation.
