Biochar: …..The Oldest New Thing You’ve Never Heard Of: Wae Nelson at TEDxOrlando
Wae Nelson was employed as a mechanical engineer in the aerospace and defense industries for many years, working both as a designer and as a manager in manufacturing. Now he publishes the magazine beloved by local gardeners, Florida Gardening, and pursues his passion for biochar — a diy, scalable technique to both improve horticultural yields and sequester carbon simultaneously.
Biochar is created by slowly heating biomass (wood and other plant materials) in a low-oxygen environment, such as a kiln, until everything but the carbon is burned off and then putting it into the ground
Biochar can help reverse rising CO2 levels in the atmosphere; improve overall soil quality, and raise soil’s water retention ability. It may also help “filter” toxic chemicals in the soil
Adding biochar to just 10 percent of the world’s croplands would store 29 billion tons of carbon dioxide equivalent. This roughly equals the world’s annual greenhouse emissions
More importantly, addition of biochar would radically improve the soil fertility and allow the production of far healthier crops
US soils alone could absorb up to 330 million tons of carbon annually with better carbon management practices. That’s enough to offset all car emissions in the US, while simultaneously boosting food production by 12 percent
