Dynamic optimization of crop production with nonuniform irrigation and nitrogen carryover and leaching is considered. A production function system with thresholds, plateau maximum, and yield reduction is estimated from experimental data; rapid convergence to a steady-state is observed. Spatial...

Groundwater provides many valuable services to society, especially as a source of irrigation water. However, over-extraction and degradation threaten the ability of many groundwater systems to continue to provide such valuable services to society. As governments consider the costs and potential...
