[QUOTE="frederick, post: 7571294, member: 11063"] So organic matter is named as such because it is material that contains carbon. Soil is simply a collection of minerals. As the organic matter decays to just minerals so soil the C is released as CO2. This is why it is only the increase in organic matter that can be counted as carbon sequestration. The trouble is as you increase the organic matter of the soil you increase the biological activity and hence the increase in CO2 emissions. From what I have read it is not long until a new equilibrium is reached when capture equals release. The greatest opportunity for sequestration is probably turning arable soils into permanent pastures but I have yet to see much scope in increasing permanent pastures annual capture. [/QUOTE]
