Recent NATURE STUDY;
Sustainable biochar to mitigate global climate change
http://www.nature.com/ncomms/journal/v1/n5/full/ncomms1053.html

Not talked about in this otherwise comprehensive study are the climate and whole ecological implications of new , higher value, applications of chars.

First,
the in situ remediation of a vast variety of toxic agents in soils and sediments.

And at USDA;

Second,
the uses as a feed ration for livestock to reduce GHG emissions and increase disease resistance.

Third,
Recent work by C. Steiner showing a 52% reduction of NH3 loss when char is used as a composting accelerator. This will have profound value added consequences for the commercial composting industry by reduction of their GHG emissions and the sale of compost as a nitrogen fertilizer.

Since we have filled the air , filling the seas to full, Soil is the Only Beneficial place left.
Carbon to the Soil, the only ubiquitous and economic place to put it.
