Supplemental irrigation represents a production technology that may be used to modify the risk-return position of a farm business. A safety-first model is used as a basis for evaluating supplemental irrigation of cotton and soybeans in the Macon Ridge area of Louisiana. The results of the application suggest that supplemental irrigation of soybeans does not substantially improve income stability on a representative farm while supplemental irrigation of cotton does improve income stability and the ability of the farm to meet its fixed obligations.
