| Abstract: | The economic impact of reducing the amount of nitrate leached out of the root zone under irrigation in the arid West was examined. The economic incentives of irrigation management were evaluated under the assumptions of both profit-maximizing and utility-maximizing (in reducing cost and effort expended in irrigation) decision-making criteria. The results indicate that there is a coincidence of interests of the farmer and the environment provided some leaching occurred. If no leaching is allowed, profit decreases markedly. Both behaviors result in less nitrate leaching than less profitable or less utility-producing irrigating practices. |
