WebbSoil carbon stocks are sensitive to agricultural and forestry practices and loss of carbon-rich soils such as wetlands. Soils in North America have lost, on average, 20% to 75% of their original top soil carbon (0 to 30 cm) with historical conversion to agriculture, with a mean estimate for Canada of 24% ± 6%. WebbWood chips deplete nitrogen from a shallow zone of soil close to the surface. However, below the first few inches of the earth, nitrogen levels actually increase after the application of wood chips. This difference occurs because microorganisms use nitrogen to decompose organic matter (in this case, wood chips), causing a depletion.
