Freshly sampled soils from across the farm. There was significant variability in soil texture and composition across the four management ecosystems, and even within each management system’s 3 spatial zones. Photo courtesy of Woods End Laboratories, LLC.

More consistent sampling and analysis of farm soil organic carbon needed for accurate test results
