What is it about?
Using known relationships between soil health and crop yields, we hypothesize that areas with constantly measured low yields will return low carbon to the soil, affecting its health. This cycle repeats itself, perhaps continuously over many years, reinforcing the equation that low yields = lower soil health. Cause and effect are intertwined.

Why is it important?
It is common to attempt to use soil health metrics based on soil analysis in a lab to explain crop behavior - one of its great pitfalls. However, we invert the formula and use broad yield (crop biomass) attributes gathered over many years to surmise higher carbon inputs, which should improve soil health. This approach helps broaden the perspective and use caution in interpreting soil health test results without accounting for more environmental variables.
Perspectives
Brinton, one of the authors, spent 25 years developing the soil health tool used in this research. This study goes beyond traditional soil health testing by integrating crop attributes and landscape factors, creating a more comprehensive approach to farm analysis.
