El Niño storms affect winter crop industry in Arizona
Friday, Jan. 29, 2016
TOLLESON – This year’s El Niño will be one of the strongest weather cycles of its kind on record, according to the National Oceanic and Atmospheric Administration. And Arizona saw its first bout of related weather in early January.
The storm, marked by four to five consecutive days of rain, increased cloud cover and left up to 3.5 inches of rain in some areas of Arizona, affecting farmers with winter crops.
Mike Etchart, one of the owners of Everkrisp Vegetables in Tolleson, said consumers might see higher prices at grocery stores.
“The market price of the vegetables have been higher because of the lack of yields and the lack of production,” he said. “It’s been pretty much area wide, so hopefully the prices that we’re getting will make up for the lack of yield and production.”
The roughly 1,500-acre farm produces everything from organic kale to parsley to mixed lettuce.
Everkrisp does 100 percent of its production in the winter, and it’s a month behind because of the weather caused by El Nino and below-average temperatures and rain in November and December.
“This year, we’re behind,” he said. “We’ve got some nice weather now, but we’re anticipating some more wet weather in the spring, so it’s been challenging.”
Of the $3.7 billion in farm sales for Arizona in 2012, 56 percent came from crop sales, according to the University of Arizona.
Overall, Arizona has nearly 1 million acres statewide of commercial agriculture, said Ayman Mostafa, a University of Arizona area extension agent for field crops.
“You already have, in some areas, about 3.5 inches of rain in only one week,” he said. “And if you know the average is 7 inches (per year), we already have half that in one week.”
The humidity also could bring other problems, like mildew and pathogens that harm plants, he said.
An increase in moisture isn’t all bad news, however.
The additional rain could help improve drought conditions in many areas. Growers like Etchart can reduce their reliance on irrigation.
“Basically, our timing of irrigation has a lot to do with the weather. We are anticipating one of the benefits from El Nino is using less irrigation water,” Etchart said.
El Nino, a worldwide climate phenomenon, can lead to storms and strong winds.
The last big El Nino events happened in 1982 to 1983 and 1997 to 1998. Maricopa, a city that has a lot of farming, saw a lot of flooding in the area during those storms, Mostafa said.
“El Nino is still a developing phenomena for us for the rest of winter,” Mostafa said. “It’s something we’re watching quite closely, and we’ll see whether that will impact especially the vegetable production here and in the Yuma area.”
Over the next few months, El Nino will likely have more of an effect in the south half of Arizona, including Maricopa and Pinal counties, he said.
