SMRT-Y Soil Moisture SensorSetting the Watering ScheduleField Capacity is the amount of water your soil will hold at equilibrium . The amount of water required to bring the moisture content of the soil from 80% of Field Capacity to 100% of Field Capacity is given by the formula:Inches of water = 0 .2 * Field Capacity * depthIf your Field Capacity is 25% and you are watering to a depth of 8 inches, then the amount of water needed is 0.2 * 0.25 * 8 = 0.4 inchesIf you know the effective precipitation rate of your sprinklers, then the watering time is given by:Run time minutes = 60 * Inches / Effective Precipitation RateIf your Effective Precipitation Rate for the example above is 0 .5 inches per hour, then the minutes watering time is 60 * 0.4 / 0.5 = 48 minutes.
