The simulation model DRAINMOD was used to determine the effect of surface and subsurface drainage on corn production for two soils in eastern North Carolina. The model uses historic climatological data to predict the day-by-day, hour-by-hour water table and soil water status for a given drainage system design. Apporximate methods, based on the stress-day-index concept, are used in the model to predict the effect of soil water stresses on corn yields. The methods include the effects of both excessive and deficient soil water conditions, as well as the influence of delays in planting date on yields. Rains and Portsmouth sandy loam soils were analyzed in this study. Simulations were conducted for both good and poor surface drainage and for subsurface drain spacings ranging from 5 m to 300 m. Most of the simulation studies were conducted for a 26-year period of record from the Wilson, N.C. weather station. Additional simulations were conducted for the Rains soil for five other eastern N.C. weather stations to evalute the effect of location differences on predicted yield responses. Economic analyses were made to identify the drainage alternatives needed to maximize profits from corn production on the two soils.
