Measuring Carbon Sequestration on the Farm
Although there are models for measuring carbon sequestration in farming soils, a cheaper and more accurate way to evaluate the carbon in the soils is to do direct measurements of the organic content of the soils, and compare year-to-year concentrations.
At the same time every year, typically after the growing season, each field is sampled for organic matter. To sample the field, you should make a composite sample of 5 to 10 samples of soil (in the top 6 inches) spaced more-or-less evenly around the field.
The carbon sequestration is calculated as the difference in organic carbon from year to year.
