Citrus crop holds steady amid cold

As a follow-up to last week's story on how the citrus industry is weathering the cold nights, orchards are still holding strong, according to California Citrus Mutual.

From the organization:
Overnight low temperatures are forecasted to moderate tonight and gradually rise for the remainder of the week. Six nights of critically cold weather kept growers busy protecting California's $2.4 billion citrus crop, over the extended New Year's weekend.

Citrus growers have run water and wind machines in their groves six to ten hours each night since December 31st, as temperatures bottomed out at 26 degrees in the coldest areas for short periods of time. Generally, the overnight low temperatures in unprotected areas fluctuated between 27 and 29 degrees for durations of one to eight hours throughout the Central San Joaquin Valley, where 65% of California's citrus acreage is located.

"Wind machines have been very effective in holding temperatures inside groves above critical levels, maintaining safe conditions and protecting both oranges and mandarins from damage," reports CCM Vice President Bob Blakely. The higher sugar content in the fruit this time of year results in a piece of fruit that can better protect itself. However, there could be some damage to exposed fruit on the outside borders beyond the range of the wind machines. There is no indication at the present time of significant damage to the remaining 75% of the navel crop, or the remaining 70% of the mandarin crop. "I do not expect to see any impact from this cold event on fruit supply or price," said Blakely.

Mandarin producers and lemon growers, on average, ran their equipment at least ten hours each night. Navel orange growers, depending on location, ran their equipment for six to eight hours. The citrus industry has spent over $16.5 million protecting the citrus crop over the past six nights.

Based on California agricultural statistics for the 2013/14 season the California citrus industry represents $2.4 billion in value with another $1.75 billion generated in economic value. The crop estimate for the 2014/15 navel orange season was 78 million cartons in the San Joaquin Valley and another 5 million cartons in Southern California. Approximately 25% of the orange crop has been harvested. Mandarin tonnage was estimated to be 50 million 5lb cartons this year and approximately 70% of the crop remains on the tree. The vast majority of lemon tonnage is in Ventura County and all of it remains on the tree. The San Joaquin Valley has an estimated 10 million carton lemon crop to be harvested with about 80% of that tonnage remaining on the tree. The entire lemon crop is estimated at approximately 45 million cartons.

A preliminary forecast by the CCM weather team for citrus production areas indicates a slightly warmer night tonight with shorter durations below freezing. Temperatures are expected to gradually warm over the next few days.
