Measuring and monitoring soil water content helps determine when
to irrigate, how much water to apply, depth of wetting and trends
in moisture content with time. Soil moisture determines the
transport and storage of dissolved nutrients and pollutants and the
availability of water to plants. The ECH2O is a capacitance probe
that measures the dielectric permittivity of the surrounding
medium. In soil, dielectric permittivity is directly related to the
water content. The ECH2O Probe provides a mV output which
correlates to Volumetric Water Content. This is a measure of volume
of soil water per unit of total volume and should not be confused
with Gravimetric Water Content. Applications for the ECH2O probe
include, irrigation scheduling and management, water balance
studies, vadose zone monitoring and landfill & hazardous waste
site monitoring.
