EC‐5 Volume of Sensitivity Application Note

One of the most important factors to evaluate when selecting a soil moisture sensor is the volume of soil that is integrated into the volumetric water content measurement.  For many field applications, a large volume of sensitivity is advantageous from the standpoint of minimizing errors caused by small scale soil heterogeneity. However, for some field applications (e.g. near surface measurements) and most greenhouse and laboratory applications, a sensor with a small volume of sensitivity is desirable. To this end, the EC‐5 soil moisture sensor is a good solution. This application note describes a set of tests that were conducted to quantify the volume of sensitivity of the EC‐5, and the results of those tests.
