Abstract
Field experiments were conducted at three sites in the Lower Coastal Plain of North Carolina to measure the water table response to subirrigation, drainage, rainfall infiltration, and evapotranspiration. The water table response to drain tube subirrigation and drainage was determined for three drain spacings on a Lumbee sandy loam soil. Results showed that water could be supplied to the root zone at a rate more than sufficient to satisfy plant needs for the 7.5 and 15 m but not the 30 m drain spacings. Theoretical calculations showed that the suggested water table depth range of 60 to 90 cm could be maintained in this soil with a drain spacing of 19.2 m. Four theoretical equations were used to calculate drain spacings using water table drawdown rates measured in the field experiments.
