Final irrigation of the growing season - Timing is everything

As the end of the growing season approaches, producers can improve their water productivity by correctly timing their final irrigation application. Early termination can lead to reduced yields. Late termination results in unnecessary pumping and energy consumption, increases the risk of soil compaction, and drains the soil profile going into winter.
