Soil regeneration and climate change

Globally, the total amount of carbon stored within soil is estimated to be 2500 gigatons (Gt), roughly equal to 3.3 times the amount of atmospheric carbon.〔Lal, R. (2004). Soil Carbon Sequestration Impacts on Global Climate Change and Food Security. Science, 304(5677), 1623 – 1627.〕 Carbon is removed from and reintroduced to soil through a variety of ecosystem processes known as the carbon cycle. The exchange of carbon between soil and atmosphere takes place rapidly and continuously.〔Falkowski, P., Scholes, R. J., Boyle, E., Canadell, J., Canfield, D., Elser, J., ... Steffen, W. (2000). The global carbon cycle: a test of our knowledge of earth as a system. Science (New York, N.Y.), 290(5490), 291–296. http://doi.org/10.1126/science.290.5490.291〕 Certain agricultural practices can deplete soil of carbon, such as monoculture, failing to rotate crops sufficiently, and intensive livestock grazing.〔Sundermeier, A., Reeder, R., & Lal, R. (2005). Soil Carbon Sequestration Fundamentals. Columbus, OH.〕 Soil that is low in carbon will not support plant life and is susceptible to desertification. Without plants, soil cannot hold water sufficiently, and will become dry and brittle over time. If there is no intervention, the land may become desertified. Scientists cite quasi-desertification as the driving force behind the Dust Bowl.〔Cook, B. I., Miller, R. L., & Seager, R. (2009). Amplification of the North American "Dust Bowl" drought through human-induced land degradation. Proceedings of the National Academy of Sciences of the United States of America, 106(13), 4997–5001. http://doi.org/10.1073/pnas.0810200106〕
