Water Balance and Irrigation Scheduler

This program calculates the number of irrigations needed for a given crop over a user defined period of time. This program assumes the level of available ground water is replenished to field capacity when irrigation is needed.

Irrigation amounts may be altered by clicking on the values. The balance is then recalculating using the user specified values.

For information on your soil type please visit the USDA Soil Survey.
