The first step in this monitoring effort is site selection on the farm. By mapping a monitoring transect, or a straight line across the surface of the Earth, we can ensure that the tests we performed are repeatable in the future. For example, we identified one of our transects by selecting two towers as the end-points. Each test is then performed along the transect.
After placing the observation hoop, we identified a grid to take our soil samples from. Samples are then taken at eight sampling points using a soil sampling probe that extracts soil cores. We then separated the cores by top, middle, and lower layers.
The monitoring effort will be repeated at the same locations in 2020. For more information on soil carbon monitoring visit: http://soilcarboncoalition.org/
