Appendix A: The Low Threshold Setting
Landscape plants are the heartiest when their roots become established several
inches down where water is stored for the longest period of time. Watering
often, for short periods of time, promotes root growth near the top of the
soil, where the moisture evaporates quickly.
e key to maintaining healthy plants with minimum water waste is to water
thoroughly–only when it’s needed. e Precision™ Soil Sensor is preset to
restrict watering until the soil moisture level drops to 50% of capacity, or 1/2
of the total moisture that can be retained in the soil. If you were to draw a
comparison to a car’s fuel tank, 50% of the soil moisture capacity would be
similar to using 1/2 of the fuel in the tank before stopping to rell. A 50%
setting restricts the sprinklers from relling the soil to capacity until 1/2 of
the moisture has been lost; causing the roots to go deeper for water. With the
capability to adjust the setting incrementally from 0% to 100%, the Precision
Soil Sensor can be ne-tuned for virtually any soil condition.
