Pre-Training and Post-Training

This study analyzed the classification capabilities of 11 participants before and after training on soil organic carbon (SOC) assessments. Before training, the New England participants accurately assigned soil classes only 41% of the time, significantly lower than the post-training accuracy of 68%. This improvement closely matched the 69% success rate of the Mid-Atlantic committee post-training. The results revealed a tendency to overestimate SOC in mineral soils and underestimate it in organic soils, highlighting the need for refined training methodologies in soil classification.

  2. New England Class Assignment Results

  3. Mid-Atlantic Class Assignment Results

  4. Summary • Not easy to estimate SOC and determine between mucky modified and mineral or organic soil materials • Without training New England folks could only assign the correct class on average 41% of the time. • Training improved our ability to assign the correct class (68%). This was essentially the same amount as the Mid-Atlantic committee got correct after training (69%) • In general we over-estimate SOC in mineral soil materials and under-estimate SOC in organic soil materials.
