An effective irrigation water management program is needed to produce efficient and profitable yields for an irrigated crop and to minimize the potential risks of leaching of some agrichemicals into the ground water. Excessive irrigation is likely to cause some agrichemicals to leach into the underlying ground water.
Several irrigation scheduling and soil water monitoring methods are available to assist the irrigating farmer in managing a crops' soil water needs and knowing when to irrigate. If the irrigation operator hasn't time to regularly monitor soil water status in the field for water scheduling, hire an irrigation crop consultant to assist in achieving an effective irrigation water management program.
Obtain more information on irrigation water management practices from personnel in the county offices of the University of Minnesota Extension Service, Soil and Water Conservation District, and Soil Conservation Service, or from their respective state irrigation/water quality specialists.
