Duchess Field Trial Harvest #2

Biochar field trials are challenging because biochar often does not show its full effects in soil right away. It's best to follow a trial for more than one year to see the results. For instance, this important study from Australia - Biochar built soil carbon over a decade by stabilizing rhizodeposits - monitored a biochar trial for ten years to learn that biochar not only added carbon to soil, it helped to stabilize additional soil carbon.

At the Duchess Horse Sanctuary, UBET volunteers helped to establish a long term field trial with researchers from Oregon State University. The trial is now in its third year and our team showed up to harvest biomass and take soil samples from the plots. We will share the results once the OSU researchers finish analyzing the materials.
