* 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

Benefits of biochar areImprove soil structureImprove water penetrationImprove water retentionIncrease pHIncrease soil lifeIncrease organic matter
Triple bottom line
Biochar:
Good for environmentGood for societyGood for the economy
How do you make biochar ?
