This Irrigation Scheduling Calculator uses real-time daily Evapotranspiration (ET) rates determined from climate stations that are linked to www.Farmwest.com.
Irrigation systems should be designed and operated to supply plant water requirements while minimizing runoff and leaching. To ensure peak irrigation system performance the system design should take into account evapotranspiration (ET), soil type and irrigation system efficiencies.
High frequency irrigation leads to increased surface evaporation and usually a higher rate of transpiration by the plants. Proper scheduling minimizes the frequency of irrigation but maximizes duration of application that is allowed by the soil and plants. It is better to have an irrigation schedule where irrigation occurs less frequently but fully utilizes water stored in the plants' root zone.
