Biochar is the new smart environmental answer to reducing carbon emissions according to Richmond New South Wales Landcare group secretary Tony Walker.
“Biochar is a very complicated product,” Walker said. “It depends what you make it from – it reacts differently.”
What is biochar?
It can be made from waste ranging from chicken litter to woodchips, manure or green waste and it had different effects in different soils. In Richmond they used chicken litter which worked well in the volcanic soils in that area.
According to scientist Dr Lukas Van Zwieten who’s working at the Wollongonbar Agricultural Research Institute, says that biochar can assist with sequestering carbon that would otherwise be released as carbon dioxide.
