Choosing the Right Water Potential Sensor in 2023

If you’re not measuring water potential, or not measuring it correctly, your data could be telling you the wrong thing. Water content measurements can only tell you so much, and inferring water potential from water content is inaccurate at best, and completely misleading in worst-case scenarios.
