Map of measured soil carbon change

Posted by Peter Donovan 8 years, 3 months ago

This is a mapping project for measured changes in soil carbon content over time (as well as Soil Carbon Challenge entries, in yellow). The purpose is not to aggregate "offsets" or to make broad predictions, but to show what's possible as verified by actual measurements. When the purpose is to show what is possible, rather than to generate a broad-scale prediction or quantify carbon offsets, questions of statistical reliability are less troubling.
