Soil salinity a key to pistachio production

California pistachio growers produce 98 percent of the U.S. pistachio crop. The remaining production is grown in Arizona and New Mexico. Soil quality is very important in pistachio production for this industry which added $1.1 billion to California’s economy in 2010. Soil salinity is a concern in pistachio production since too much salt can reduce yields and create other problems. Farm Press talks with Blake Sanden, University of California farm advisor in Kern County. Kern is the largest pistachio-producing county in California.
