In order to effectively manage plant available water in the soil, the CCA needs to consider the water balance – the sum of the inputs and outputs of water into the soil bank. Evapotranspiration is a chief component in the soil water balance, and can be used like an accounting tool to identify when irrigation is necessary and how much water to apply. The most common ET estimation methods will be discussed, and how they can be used for irrigation scheduling. Plant canopy temperature is an indication of plant water stress, and infrared thermometry (IRT) may be used to identify when plants reach a stress threshold temperature at which irrigation should be initiated.
