Abstract

While irrigation has been used to increase crop yields, increase profitability and reduce production risks, interest in subsurface drip irrigation (SDI) offers new spatial management opportunities. Producers must consider irrigation strategy (uniform rate, variable rate), water storage (e.g. optimal pond location) and management zone delineation. Results of this study help substantiate why interest in subsurface drip irrigation (SDI) has increased. Uniform rate SDI is shown to be most profitable when water resources are not limited, while variable rate SDI is economically advantageous when water resources are limited. Site-specific pond location according to soil type also shows particular economic promise.
