4. BaseStation 1000 Irrigation Controller Lower Threshold Moisture Sensor Based Watering If you have a Baseline soil moisture sensor biSensor installed in your landscaping and connected to your BaseStation 1000 irrigation controller you can program the controller to water based on the moisture levels in the soil This watering strategy can reduce outdoor water use by up to 62 percent or more over traditional irrigation methods And by watering your plants when needed you can increase landscape health promote deeper root growth and make your plants more disease resistant The BaseStation 1000 irrigation controller supports several biSensor based watering strategies but Baseline recommends the lower threshold also referred to as less than limit or lower limit configuration as a general watering strategy Overview of Soil Moisture Levels The amount of moisture held in the soil varies depending on the type of soil and the amount of time between watering events When you re using a sensor based watering methodology you should have a general understanding of the water holding capacity of various types of soil We ve included a brief description of the standard soil moisture content levels in this document You can learn more about soil moisture content soil classification and infiltration and water movement in Baseline s document titled Watering with Soil Moisture Sensors Soil moisture content is identified by the followin
