> "such burned, dead matter fertilizes better than compost and animal manure"

> the "better than" comparison of biochar vs. compost+manure is false and

> the sentence should have more accurately read
> such burned, dead matter *added to* compost and animal manure fertilizes *better

> "enhances soil's natural ability to seize carbon"
> should include *nitrogen* as well as carbon
> a far more deadly GHG -- 289x more deadly.

> 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
