Australian soil scientist Christine Jones has a new paper out that summarizes much of her conclusions about the soil carbon opportunity. "For some time, analysts have tipped carbon to become the world’s most traded commodity. The reality is that it has been the world’s most traded commodity for millennia." She also describes the crucial role of mycorrhizal fungi, and characterizes many of the conventional practices of modern industrial agriculture, such as the application of water-soluble nitrogen and phosphorus, along with soil disturbance, as inimical to the accumulation of beneficial carbon in the soil. Soil carbon -- can it save agriculture's bacon? Highly recommended, attached below.
