Sand County Foundation Measures Impact of No

We tagged along with field projects director Greg Olson, as he installed the CropX soil moisture and temperature sensors on the farm across the street from Ross, which is under conventional management. The sensors collect soil moisture and temperature readings at 4-, 12- and 22-inches.
By comparing data from fields under soil health management with data from adjacent conventionally managed fields, farmers will better understand how management can influence water infiltration and holding capacity, leaching potential, aggregate stability and other critical soil properties. I asked Greg for some of his biggest takeaways from the study so far.
“One of the things we tend to see is there’s better water management in the soil of the soil health systems. Now, I’m not going to say it’s drastic, but we’re seeing it’s better. During a drought, we had sites in Dodge County years ago, and we noticed when the drought hit, the soil health system was maintaining about 1-2% better soil moisture in the peak of the drought, which that could technically be … when you’re getting close to wilting point and crop death … that could be an extra couple days or even a week or two. That’s critical in a drought.”
“In the opposite side of the things, when it comes down to these extreme rain events we have, the soil health management systems are able to infiltrate a little better from what we’ve seen, so that means they’re managing that water better from both sides —keeping the water when you need it and migrating it out when there’s too much.”
If you’re wondering what the soil health management principles are…Sand County lists 6 of them: minimize soil disturbance, maximize soil cover, maximize plant diversity, maximize presence of living plants/roots, integrate livestock and know your context.

Executive Summary

Field projects involved installing CropX soil moisture and temperature sensors on a farm under conventional management to compare data with adjacent fields. The sensors collect readings for soil moisture and temperature at 4, 12, and 22 inches depth. Comparisons between fields managed under soil health systems and conventionally managed fields allow farmers to understand how management influences water infiltration, holding capacity, leaching potential, and aggregate stability. A key takeaway from the study is that soil health systems demonstrate better water management; during a drought, these systems maintained approximately 1-2% better soil moisture compared to conventional systems, potentially extending water availability by a few days or weeks near wilting points. Furthermore, in response to extreme rain events, soil health management systems demonstrated improved infiltration, suggesting they better manage water by holding it when needed and moving excess water out when it is abundant. The principles guiding soil health management include minimizing soil disturbance, maximizing soil cover, maximizing plant diversity, maximizing living roots presence, integrating livestock, and knowing the local context.

Full Take

The comparison between managed and conventional fields illustrates a fundamental divergence in hydrological response under stress. The observed resilience in soil health systems—maintaining higher moisture during drought and improving infiltration during heavy rain—suggests that the underlying management principles (minimizing disturbance, maximizing cover/diversity) create a more dynamic and effective soil matrix for water regulation. This moves beyond simple observation of where water is present to understanding the physical mechanisms governing water dynamics. The takeaway regarding drought resilience (1-2% better moisture retention) points to an internal capacity within the soil structure that buffers external climatic shocks, which is contingent upon the physical state of the ecosystem—namely, living roots and organic matter distribution. The principles listed provide a framework for operationalizing this biological reality into tangible soil physics. The implication is that management is not merely an input or output action, but a mechanism for optimizing biophysical properties that directly influence water security. This pattern suggests that resistance to environmental volatility is less about resisting the weather itself and more about fostering biological complexity that enhances the soil's inherent physical capacity to store and regulate moisture. What is missing is a quantitative understanding of how specific management practices translate into these measured soil property changes across diverse climatic regimes, which would further strengthen the causal link between action and outcome.
