John Schendel took the January 2008 Earth Activist Training course. Since then, he has done some literature searching and analysis on sequestering carbon dioxide in soil using various approaches including permiculture techniques, namely no-till agricultural practices. Two people, Abe Collins and Darren Dougherty, have reportedly asserted that humans can reduce atmospheric carbon dioxide concentrations to pre-industrial levels by increasing the soil organic carbon (SOC) content in the top one foot of the world's agricultural topsoil by 1.6 percent annually over a ten-year period. This assertion is reportedly based on the work of Allan Yeomans and his book Priority One. John reviewed the assertion and discusses his findings in a document posted on the Resources and Publications list for this group, under the headline "Sequestering CO2 in Soil". His findings are based on assumptions about how the assertion made by Mr. Collins and Mr. Dougherty was derived. John is interested in feedback on his write-up and whether or not it accurately reflects the basis of the assertion. Any feedback is welcome.
