Abstract: This study compares subsurface drip irrigation and sprinkler irrigation with respect to expected returns, aquifer life, nutrient utilization and accumulation in the production of irrigated corn using swine effluent and fresh groundwater from a depleting aquifer in the Oklahoma Panhandle. Most of the equations estimated econometrically had heteroskedasticity problems and MLE was used. The econometric estimation of a PDF of ammonia volatilization dependent on amount of nitrogen applied, for each irrigation system, was successful and is the basis for developing a stochastic chain for the soil nitrogen carryover equation. The results of the stochastic dynamic programming model are still being developed and will be presented at the conference.
