How does the moisture meter method work to determine moisture content?

The moisture meter method determines moisture content by measuring the electrical resistance within the soil. In this technique, as moisture levels increase, the conductivity of the soil also changes. Wet soil has a higher conductivity compared to dry soil because water acts as an electrolyte, allowing electrical currents to flow more easily.

The moisture meter typically uses electrodes inserted into the soil to measure the resistance or conductivity. By calibrating the device against known moisture levels, it can accurately provide a percentage of moisture present in the soil. This method is particularly useful for providing quick and non-destructive readings, making it a preferred technique for field inspections and soil assessments.
