Going to the expense of shifting a parcel of land from dryland farming to the production of irrigated crops may—or may not be—profitable. In this study six alternative uses were compared for six parcels of land that were the same in every way except size. For ladino seed, canning olives, and irrigated pasture used either for growing out dairy heifers or the production of Grade A milk, the opportunity for profit improved as the size of the operation increased. On the other hand shifting from dry land barley to irrigated grain sorghum made a bad situation worse.
