Soil structure and texture affect how well a soil moisture sensor works. Researchers tested sensors in disturbed and undisturbed soil samples. They found that undisturbed soil calibrations were more precise in measuring soil water depth. Undisturbed calibrations also helped better estimate water demand and prevent over-watering. The sensors had higher accuracy in undisturbed soil setups compared to disturbed ones. Overall, using undisturbed soil samples led to more accurate measurements of soil water content and depletion.
