Hello all,
Do forgive me if I am sharing information that is common knowledge! I refer to a magazine article written in
The Digger's Club (yes, I have referred to it in a previous thread!) entitled
The Organic Solution to Climate Change. All quotes are stated by organic leader Tim Marshall --

Soil is the largest carbon sink over which we have control. It holds twice as much carbon as the atmosphere, and twice as much as all the vegetation on Earth, including forests. Sixty percent of the Earth's surface is used for agriculture. This soil can remove more CO2 from the atmosphere faster and more economically that trees or any other method . . . . Soil carbon is more stable. Trees can be burnt and trees drop leaves so they shed carbon during winter and droughts . . . . The most efficient method of accumulating carbon in soils must be by direct decomposition of plant material. Soil carbon is created my bugs and microbes living and dying as a consequence of the vigorous root action in the soil. The rotting remnants of organic matter feed the microbes that produce soil carbon . . . ploughing disturbs microbes, dries out the soil, and releases CO2 into the atmosphere . . . if farmers went back to a grazing/cereal crop rotation, as organic wheat farmers do, organic levels will rise, as manure and grass provide good conditions for microbes below the ground . . .

If governments would actively support self-sufficiency, oh, what a world this could be!!
Soils - a better carbon sink
