What are Humic Substances and How Do They Help with Climate Control by Sequestering Carbon?

How to Calculate Carbon Sequestration Potential from Applications of Humic Substances.

Increased carbon sequestration from humic acid addition to soils will be gradual, but most sequestration will result from increased biomass growth stimulated by use of humic products in impaired soils which otherwise are not amenable to biomass cultivation. For example, about 3-4 tons/yr of CO₂ is captured on each acre of land with tree biomass planted only on 10% of land, which can be intercropped with food crops on the remaining 90%. The Kyoto Treaty qualifies this reduction for a 70-years average active growth cycle of trees via the provisions of clean development mechanisms. Other approaches still under consideration indicate acceptance of this approach for 100 years or more, since trees can sequester CO₂ for centuries.

The humic fertilizer applied at a rate of 50 gallons per acre per year will result in producing food and tree biomass on 20 acres of land and thus sequestering 60 tons of carbon dioxide in tree biomass per year even if estimated at a low rate of 3 tons of CO₂ per year per acre.
