Using Soil Moisture Sensors for Automated Irrigation Manual irrigation is labor-intensive and repetitive, so it is one of the first greenhouse tasks that should be automated. Although automating irrigation is easy, automated systems are not necessarily water efficient. Combining soil moisture sensors with irrigation controllers can result in automated irrigation systems that can water crops based on the actual water use of the crop with minimal to no water leaching. Measurement and Control of Plant Drought Stress Levels Soil moisture sensors also have important applications in drought stress research because of the need to quantify the severity of the imposed stress. Not only can these sensors be used to measure the severity of drought stress, they also can be used to control the drought stress level. Join guest speaker Marc van Iersel from the University of Georgia for a presentation addressing two key areas in irrigation management where soil moisture sensors have been used beyond measuring the water content of soils or soilless substrates.
