ABC Interview with Ozzie Biochar Luminaries
LUKAS VAN ZWIETEN: We're getting very significant improvements in yield in our cropping situation. We've increased yield of sweet corn from 16 tonnes up to 35 tonnes of fresh cob per hectare and we've more than doubled our yield of fibre bean crops as our winter crop. So we're getting quite significant and also economic returns on the investment of applying biochar to soil.
STEPHEN KIMBER: We've seen very significant impacts in the laboratory where things are a lot easier to measure and we've had up to a 90 per cent reduction in nitrous oxide generation. Nitrous oxide is important because it has a potency of around 300 times that of carbon dioxide. So small fluctuations in the nitrous oxide story have a profound influence on the overall greenhouse gas story.
MALCOLM TURNBULL: For the life of me I cannot understand why they don't do it. It is pretty straightforward. It's readily measured. The science is very well known. It's been around for centuries, thousands of years, in fact. So it's something that we should just get on with and support.
TIM FLANNERY: I would argue using these technologies to repay our historic debt to the world, calculate how much carbon pollution we put in the atmosphere over the last century and seek to repay it using biochar and other biological carbon options.
