This paper is concerned with the profit‐maximizing choice of water quantities given the choice of crop and water quality but taking into account the dynamics of salt accumulation over time. The optimization model formulated in this paper is based on a detailed representation of the salt transport process in soils but assumes known or average rainfall levels. Optimal water quantities and soil salinities in steady state were calculated for navel oranges in two areas of California. Water applications sufficient to maintain maximum yields were found to be optimal in many cases.
