Long-Term Salinity Buildup on Drip/Micro Irrigated Trees in California

The Irrigation Training & Research Center (ITRC) of Cal Poly State University, San Luis Obispo, CA, hypothesized that there is salinity accumulation in the root zone of tree crops that have been irrigated with drip or micro-spray irrigation systems, located in arid and semi-arid regions.  Therefore, a study was conducted by ITRC during the summer of 2002 to examine the long-term impact of drip and micro irrigation on salinity accumulation in orchards, focusing on the salinity concentration pattern across a soil profile.  The project also provided information to support recommendations on the most effective and efficient leaching techniques.
