Abstract:

Drip irrigation of processing tomatoes in the saline soils along the West Side of the San Joaquin Valley of California was found to be highly profitable compared to sprinkler irrigation, even in the presence of very shallow, saline ground water. Some tomato growers on salt-affected soil now use drip irrigation to produce nearly all of their tomatoes, but there is concern about the long-term sustainability. This project has shown that salt distributions around the drip line clearly have a relatively low-salt zone near the drip line. It is in this zone where most of the roots exist; where soilwater content is the highest, and where nearly the entire soilwater uptake by the plants occurs. Thus, as long as sufficient leaching occurs near the drip line and the same drip line placement is always used, then there is a reasonable expectation for long-term sustainability.
