Deficit irrigation strategies with varying effectiveness can be employed in many cases to maximize production and profit. These strategies can include modifying irrigation schedules, concentrating irrigation to critical crop growth stages, reducing rates,...

It is important to consider the possible hydrologic impacts of irrigation optimization efforts to avoid implementing practices that have little appreciable effect relative to the desired outcome. Examples of desired outcomes include increasing supply reli...
