Palo Verde Valley Prepares for Fall Crops
October 3, 2014
Dr. Vonny Barlow, a UC Cooperative Extension Entomology Farm Advisor in Blythe located in Imperial County, reports the Palo Verde Valley has a lot of activity this time of year.
“Currently we’re transitioning out of the summer crops; temperatures are getting cooler; we’re no longer in the 114° to 116° F zone; and nighttime temperatures are dropping. So we are transitioning to our late fall/winter crops, which is predominantly lettuce in the Palo Verde Valley,” said Barlow.
“A lot of those growers out there are pre-irrigating their fields now to increase soil friability—to break it up so that when they come in and mulch the soil, they can create fine soil and soil particles—because lettuce seed needs good soil contact for it to imbibe water and germinate,” said Barlow.
“The Palo Verde Valley is unique in the desert in that it is a highly productive agricultural region. It’s the second largest alfalfa production in that area outside the San Joaquin Valley, and it actually has greater production than the inner-mountain areas in Northern California. We have plentiful sunshine, good soil types, easily-drained soils, and available water for irrigation, so that’s the trifecta for agriculture,” said Barlow.
