Soil Carbon Sequestration: a Surprising Opportunity to Heal Ourselves and the Planet at the Same Time

  • Soil provides habitat to an extremely complex and diverse microbial ecosystem. To cite one example, Dr. James Tiedje at Michigan State University’s Center for Microbial Ecology estimates that a 1/4 acre woodlot would have about one million species of bacteria, a teaspoon of that soil housing between 600 million to 1,000 million individual bacteria. Fungus is also a key component in soil. Vast mycorrhizal networks of fungi connect individual plants together and play a critical role in the storage and distribution of nutrients and water. These networks are integral with the carbon cycle and the health of above-ground plant life (see interview with Elaine Ingham here).

  • And finally, in addition to this carbon sequestration potential, improving soil health has the following additional benefits: the ability to hold more water to hedge against drought, increase biodiversity and plant pest and disease resistance, grow healthier food through boosting nutrient density in plants, and increase productivity, or crop yields. Simply put: increasing carbon content in soils lifts many boats at the same time and is the right thing to pursue regardless of its impact on the climate.
