Abstract

In irrigated cropland of the semi-arid and arid regions of California, the lack of drainage outflow requires reassessment of crop rotation patterns. As regulatory actions place limits on drainage water quality and quantity, growers will be forced to manage water more efficiently and rely more heavily on salt-tolerant crops. Improved water use efficiency depends on integrated cropping systems in which cultural practices interact to reduce leaching requirements while maintaining productivity, profitability, and the environment. The success of this approach will require a better understanding of the physiological basis of plant salt tolerance and the evolution of soil properties as influenced by crop rotation, tillage, crop residue and soil fertility management. An increased commitment to evaluate such interactions in long-term field studies is needed.
