Abstract: Surge irrigation was compared to continuous flow in Nebraska from 1983 - 1990. As a result of surge irrigation, advance inflow times were reduced an average of 20 percent compared to continuous irrigation treatments. The effects of furrow packing and surge irrigation both individually and combined were evaluated in 1989 and 1990. Continuous irrigation in packed furrows provided similar results to surge irrigation in soft furrows. When surge irrigation was used in combination with furrow packing, advance inflow times were reduced approximately 9% more when compared to either continuous irrigation in packed furrows or surge irrigation in soft furrows.
