[Terrapreta] In Brief article in Scientific American

[Sean K. Barry]

Hi TP List readers,

There is an "In Brief" article on page 38 of the June 2008 edition of Scientific American on Terra Preta

CHARRED FOR LIFE
In the heart of the Amazon River basin 1,500 years ago, tribes mixed soil with charcoal derived from animal bone and tree bark to boost their crop yields. Now scientists conclude that such burned, dead matter fertilizes better than compost and animal manure, helping to transform the soil into the richest earth in the world. The "biochar" also profoundly enhances soil's natural ability to seize carbon, thereby trapping greenhouse gases. Delaware State University researchers presented their findings April 10 at a national meeting of the American Chemical Society.
