A decade ago Scientist discovered what is known by the Indios as Terra Preta or Black Earth and turned out be a part of instruments at our disposel to combat climate change. A incredible BBC documentary from 2002 reveals this story.

From VC Reporter by Shelby Maloney:
In the race against the clock to find new ways to fight climate change, Agromin, an Oxnard-based organic recycling company, plans to aid in the effort to modernize an ancient soil enhancement technology by developing its own version of a charcoal-like soil amendment known as biochar. Biochar is produced from organic biomass, or plant waste, and is known to have several environmental benefits, including carbon sequestration, the act of taking carbon out of the atmosphere.

Bunny Guinness from the Telegraph: We’re nation of weather watchers, and the gardeners among us are getting extremely concerned. Even if we get a drenching this month, the hosepipe ban in many areas looks set to stay for the summer. It’s time for a rethink about the way we use water in the garden.

Mashable:
Big Idea: Utilize organic waste to create carbon-negative charcoal, a substance that pulls CO2 from the air and helps crops grow taller and stronger.

Why It’s Working: Re:char’s mission is about providing farmers — both at home and in developing countries such as Kenya — with conservation-oriented soil-boosting complexes that can double food output compared to traditional farming methods.

You can buy now "Biochar action T-Shirts" with glow in the dark effect. This is a pretty cool idea to spread the message about this high potential soil amendment and to support the Biochar Earth Network!

From PR Web: Worm condos. Terra Preta. Black Gold. Whatever it’s called, healthy soil is the most important tool in successful gardening. With the new Soil Reef™ blend being launched this spring, gardeners can create a healthy, organic and permanent home for beneficial organisms living in the soil.

The new blend combines OMRI-listed compost and worm castings from Organic Mechanics® with biochar, adding a unique porous carbon to the soil to create a habitat for life to thrive. How does it work? Soil Reef creates a network of nearly permanent, natural carbon structures throughout your soil, which hold onto water and nutrients, and create homes for microorganisms.

So says Robert Brown, a professor of engineering at Iowa State University and a leader of the university’s Initiative for a Carbon Negative Economy and its Bioeconomy Institute. Those are interdisciplinary campus efforts to develop ways to remove carbon dioxide from the atmosphere by growing plants or algae, making them into fuels and burying their carbon residues in soil -- and make money doing it.

The notion that we can generate wealth and remove CO2 from the air is obviously appealing. As atmospheric concentrations of CO2 rise and climate risks grow, so does the need for carbon-negative technologies that pull CO2 from the air, as plants do, and then store it underground or deep in the ocean.

The use of Biochar to act as a carbon sink is causing quite a stir among environmentalists and scientists alike. This ancient technology of burning organic matter then burying it in the ground to fertilize crops may have been around for over 3000 years in the Amazon Basin, but the research that shows that this method of fertilization will also absorb some of the carbon in the atmosphere means that this could be a really viable solution to the long term problem of carbon over production.
