* What is it ?* Whats it for ?* How do you make it ?

Biochar

Terra Preta Amazonian rain forest between circa 450 BC and 950 ADBiochar is not new:

Typical: biochar under microscopeProperties of Biochar

When making (pyrolysis)Reduces Smoke (Haze)Greenhouse gas (GHG) reduction: pyrolysis Vs. field burning (approx 60% reduction)

When UsingSoil enhancementAdsorption of nutrients, beneficial micro organisms and waterIncrease yieldsPesticide and toxic adsorptionGreenhouse gas (GHG) reduction: carbon sequestration

Sustainable development

Reduce haze
