Technical Abstract: Drip irrigation offers several advantages over other irrigation methods in humid areas, including lower labor need, ease of automation, lower water pressure, lower water flow rate, and improved management of water and nutrients. System cost can be reduced and drip irrigation made more profitable for some agronomic crops through the use of wider spacing and subsurface placement of laterals. Yields were lower for a wide lateral spacing (6 ft.) in only one of six years for corn and none of seven years for cotton. Consequently, subsurface placement of laterals at wider spacings has significant potential for profitable irrigation of agronomic crops in the southeastern Coastal Plain.
