Matric potential is expressed in units of centibars (cbar) and is a measure of how tightly soil particles hold moisture.
A sensor placed in saturated soil will show a reading of near 0 centibars. As soil moisture is depleted due to evapotranspiration, the matric potential increases.
Tensiometers were used to monitor soil moisture content at a 30-cm depth, with irrigations triggered when readings reached 40 to 50 centibars. However, this irrigation schedule often had to be adjusted (either accelerated or delayed) to accommodate required insecticide spraying and any resulting restricted reentry interval.
