Avocado trees tolerate salinity

San Diego County's avocado growers have been struggling for years with the soaring cost of water and mandatory cutbacks in its use. But several dozen trees on the Nick Stehly Ranch provides the $137 million industry with a rare cause of optimism.

From the North County Times:

San Diego County's avocado growers have been struggling for years with the soaring cost of water and mandatory cutbacks in its use. But several dozen trees on the Nick Stehly Ranch provides the $137 million industry with a rare cause of optimism.

The experimental trees are thriving, and producing fruit, on irrigation water so salty that ordinary trees won't bear fruit. Native to the highland rain forests of tropical Mexico, avocados are one of the most salt-sensitive crops. Water fresh enough for humans to drink can be too salty for avocados.

On a recent visit to the ranch, the more productive experimental trees were covered in profuse greenery, bearing large avocado clusters.
