Carbon Sequestration Methods Under Consideration

July 24, 2009 07:00 PM

The following information is a Web Extra from the pages of Farm Journal. It corresponds with the "Policy Journal” by Roger Bernard. You can find the article on page 40 in the Summer 2009 issue.

The following are carbon sequestration methods on agricultural lands, grasslands, rangelands, and forested lands that have to be considered as the list of approved offset projects is drawn up:
  • Soil tillage methods
  • Winter cover cropping, crop rotation, and other means of increasing biomass levels in soil, other than leaving fields fallow for periods of time after harvesting
  • Converting croplands to grasslands or rangelands, provided that such lands were not forested within 10 years of the projects initiation
  • Reducing nitrogen use or using nitrogen more efficiently (nitrogen is a common ingredient in fertilizers)
  • Reducing the frequency and duration of rice paddy flooding
  • Changes in livestock feed and other livestock management practices that are designed to reduce livestock "emissions”
  • Planting forests on lands not considered forests as of the beginning of 2007
  • Changes in timber production and harvesting designed to capture carbon emissions
  • Reduced deforestation
  • Preservation of peatlands or wetlands
  • Development of technologies designed to increase the carbon capture potential of forested lands
  • Reducing carbon emissions from organic soils
  • Reduction in emissions from manure and effluent
  • Aeration of fields with waste products
  • Biogas capture and combustion
In addition, the following items would be required to be considered:
  • Planting trees in urban areas
  • Recycling and other waste minimization
  • Methane collection and combustion projects at mines, landfills, and natural gas plants;
  • Emissions reductions at water treatment plants
  • Capturing and geologically sequestering uncapped greenhouse gas emissions with or without enhanced oil or methane recovery in active or depleted oil, carbon dioxide, or natural gas reservoirs
  • Capturing and destroying, or avoiding greenhouse gas emissions from industrial sources
