Row crop agriculture in Virginia and other Eastern states is largely rainfed, but there is increasing interest in irrigation as a way to manage dry periods and weather variability. However, irrigation systems require substantial installation and operating costs, and it can be very difficult determine if yield improvements will be sufficient to justify these costs. This publication provides an overview on the Irrigation Financial Estimator Tool, which was recently developed to help row crop producers estimate financial aspects of supplemental irrigation. The tool estimates installation and operating costs, as well as revenues from improved yields, using user-supplied information and historic data on weather and prices for crops and fuel. It accounts for uncertainty in these estimates by presenting a range of values for each cost.
