Restoring soil carbon can reverse global warming
Erich J. Knight, February 21, 2008

Here is a strait forward conversion of the impact of building soil organic material (SOM) on ppm of GHGs using just marginal land.

Tony Lovell of Soil Carbon P/L in Australia estimates that by actively supporting regrowth of vegetation in damaged ecosystems, billions of tons of carbon dioxide can be sequestered from the atmosphere.

Soil Organic Carbon
Jan Skjemstad, CRC Greenhouse Accounting

In Summary

Soil OC is a significant source and sink of atmospheric CO2

Soil is a complex, biologically active medium

Soil OC is not one material

Changes in SOC can be measured directly or can be modelled

The C sink value of soils is limited BUT increasing and maintaining SOC has many benefits for improved productivity and soil resilienceMysneakers | Patike

Manage carbon to sustain soil structure
Jan Skjemstad, CSIRO LAND AND WATER AND CRC FOR GREENHOUSE ACCOUNTING in FARMING AHEAD No. 158 March 2005

Soil organic carbon plays a critical role in the biological, chemical and physical health of a soil. But little is known about how crop management impacts on soil organic carbon levels and thus soil health. This article describes how a new approach to understanding this relationship could help farmers better manage soil organic carbon.

On highly weathered soils in tropical and subtropical climates, maintenance of soil organic matter is essential to sustain system productivity and avoid rapid soil degradation. But climatic conditions as well as soil characteristics favor the rapid decomposition of organic matter. However, several recent studies indicated that black carbon, the product of incomplete combustion of organic material, could combine characteristics highly beneficial for soil nutrient dynamics with high stability against chemical and microbial breakdown.
