Why Practice IWM?
Practicing IWM can help:
Minimize water quality problems;
Reduce energy costs; and
Improve crop quality and yield.
Distribution and application uniformity;
How irrigation timing and soil water holding capacity affect irrigation scheduling; and
How a soil moisture monitoring system is useful in irrigation scheduling decisions.
Install at least one soil moisture monitoring probe per field;
Provide a graph for each field of documented soil moisture readings for the entire season;
Provide total precipitation in acre inches for each field at season end, including rain and irrigation;
Document daily evapo-transpiration (ET) for the field through the irrigation season. Provide documentation of projected, scheduled irrigation recommendations throughout the season;
