Irrigation scheduling is the process of deciding when and how much irrigation to apply to a field. Applying too little irrigation water can cause crop losses and yield reduction, but applying too much water can waste money, fertilizer, and labor, and can even decrease yields in some cases. The goal of this bulletin is to provide information that can help irrigators schedule irrigation using the checkbook method. It describes some of the benefits of irrigation scheduling and general factors that influence the amount and timing of irrigation needs. It then describes the data needed for checkbook irrigation scheduling and how to get this data, the calculations involved, and software/apps that can be used to help with these calculations.
