The Millbrook Independent: The Futility of Soil Carbon Sequestration

"For a long time, farmers have realized that soil organic matter improves the quality of soils, by improving water-hold capacity, friability, and nutrient content. But, however we do it—fertilization, irrigation, manuring, reduced tillage, and planting cover crops—increasing soil organic matter doesn’t look like such a good idea to mitigate climate change. The chemistry of humus substances includes a substantial amount of nitrogen and phosphorus that will limit our efforts."
