Schohr,whoworks inButte, Plumasand Sierra counties, said the Ag Pass program has been critical to helping ranchers tend to theirherdsdespite the fire. Theprogram issues passes, with the aid of the county sheriff and agricultural commissioner’s office, to farmers and ranchers so they can travel behind the lines to check on their livestock andproperty. “The concept of that is really working as it was intended to,” Schohr said. “We’ve hadranchersbeable togo inandcheckon cattle that are behind evacuation zones.” Some ranchers rely on well water to slake their animals’ thirst, and getting generators into the area to ensure reliable water supplies has been vital, she added. Some cattle in the Chester area have been returned to their home ranches, Schohr said. In addition, she’s helped one rancher evacuate cattle from the area and assistedotherswhosecattlehadbeensold and were under contract to ship within specific time frames. “Most of the cattle in this area are mi- gratory cattle,” Schohr said. “They’ll spend their winters in the valley and foothills, and then they’ll spend their summers at the higher elevation.” Fire is not the only threat facing these ranchers and their livestock, Schohr said. “We’re not only facing a fire, but in that valley they had significant forage loss due See FIRE, Page 4 Efforts mount to save livestock fromwildfires

Delta water cutbacks weigh on farmers Contra Costa County farmer Al Courchesne, at his Brentwood orchard, says he is concerned about water curtailments due to regulations for the Sacramento-San Joaquin River Delta watershed adopted by the State Water Resources Control Board last week.

Attention employers: Rules change for unpaid leave By Erica L. Rosasco

more employees within a 75-mile radius are also required to grant up to 12 weeks ofmedical leave under the federal Family andMedical Leave Act. In the past, CFRA provisions close- ly overlapped the requirements of the FMLA, and leave time grantedunder one act would simultaneously exhaust the leave available under the other. However, the newversion of the CFRA expands the scope of familymembers for whom leave is available beyond those listed in the FMLA. They now also include grandpar- ents, grandchildren and siblings. Leave granted for the care of those familymem- bers under the CFRA would not exhaust leave available under the FMLA. This could require an employer to pro- vide for up to 24 weeks of leave to a sin- gle employee within a 12-month period. For example, an employee could take 12 weeks of leave to care for a sibling under the CFRA and then take an additional 12 weeks of leave time to care for their child under the FMLA. California employers with at least five employees must now be careful to com- ply with the provisions of the CFRA. The Farm Employers Labor Service, an affil- iate of the California Farm Bureau, will be hosting a webinar regarding the ex- pansion of the CFRA to small employers. I will conduct a webinar to help agricul- tural employers better understand this recent expansion of the CFRA at 10 a.m. Aug. 27. To register, go to https://www. fels.net/1/ and click on “FELSWebinars.” There is no cost to attend, and I hope you can join us for answers to your ques- tions about CFRA expansion. (Er ica L .

Cal i fornia employers need to be aware of significant changes to the California Family Rights Act that be- came effective at the start of 2021. For the first time, employers with fewer than 50 employees are subject to the law and need to take steps to educate themselves on complying with their new obl igations. Larger employers that were previously subject to the law should also be aware of changes to their obligations and update their policies to ensure compliance. The CFRA requires employers to pro- vide qualifying employees with up to 12 weeks of unpaid leave for medical and family care reasons. They may include an employee’s illness, a familymember’s serious health condition, or the birth or adoption of a child. Employees qualify for leave if they have worked for the employer for at least a year and for at least 1,250 hours in the past 12 months. If such an employee re- quests leave, the employer must grant the request and guarantee that their job (or a comparable position) is available when they return. The employee may take the leave all at once or intermittent- ly, and the employer must continue to provide health insurance coverage to an employee onCFRA leave under the same conditions as coverage would have been providedhad the employee been actively at work. Before 2021, the CFRA applied only to employers with 50 or more employ- ees within a 75-mile radius. But since Jan. 1, California employers with as few as five employees are subject to the CFRA’s complex and potentially bur- densome obligations. As most small businesses have never had to deal

For the first time, businesses with fewer than 50 employees are subject the California Family Rights Act and must comply with rules for unpaid family or medical leave.

with protected medical leave before, there is a steep learning curve to com- ply with the new law. Employers who are subject to the CFRA for the first time should be sure to draft compli- ant CFRA leave policies and institute leave procedures. They will need to approve, administer, and track employee leaves. Compliance can be tricky, and employers should seek expert guidance to ensure theymeet their new obligations. The change in the law also presents new challenges for employers of 50 or more employees that may be used to complying with the former CFRA. Several exemptions in the law no longer apply, and the scope of family members for whom leave is available has been ex- panded. The changes also affect how the Act interacts with other laws that require these employers to provide leave time.

Accordingly, larger employers will need to update their practices to comply with the changes. Before 2021, the CFRA had a “key employee” exemption that allowed an employer to refuse to grant leave to a salaried employee who was among the highest-paid 10 percent of the employ- ees within 75 miles of their worksite. Additionally, an employer of both par- ents of a child were required to provide only up to 12 weeks of leave to care for the child between the two employees. Both exemptions have been eliminat- ed. Employers may not refuse to provide leave to key employees and must grant each parent-employee the full 12 weeks of leave time. The change in the lawcould require an employer to provide twice asmuch leave as before. In addition to leave required under the CFRA, employers with 50 or

Sales of organic products spike during the pandemic

mental and consumer demands contin- ue to increase,” Jasiello said. The Organi c Farming Research Foundation in Santa Cruz, which regu- larly surveys organic farmers about their needs and challenges, will be doing a special report on California trends us- ing data from its 2020 national survey, said Executive Director Brise Tencer. That report will be available in the fall, she noted. In its 2016 survey, irrigation and drought management came up as top

needs for organic farmers, she said, with soil health, biology, quality, nutrient management and fertility management being close behind. The foundation has invested in re- search to help support development of quality strawberry transplants for or- ganic systems. It is also developing in- tegrated irrigation management strate- gies to improve water and nutrient use efficiency in organic processing tomato

ByChing Lee Home cooking during the pandemic has liftedoverall sales of organicproducts in California and across the U.S. As people worked from home and ventured out l ess f requent l y , the market for organic products jumped by more than 12% to nearly $62 bil- lion in 2020, according to an annu- al survey conducted by the Organic Trade Association. Highlights of that survey were shared during a meeting of the State Board of Food and Agriculture, which focused on California organic agricultural pro- duction. The monthly meeting, held last week via webinar, included speak- ers who discussed market trends, re- search and emerging issues related to organic production. “Shoppers real ly deeply stocked pantries and freezers, so lots of cat- e go r i e s had p r e t t y b i g up t i ck s ,” said Angela Jasiel lo of the Organic Trade Association. Sales of organic food grew nearly 13% to more than $56 billion, according to the survey. Organic fruits and vegetables, which now account for 15% of the total U.S. retail produce market, saw notable gains. Fresh organic produce sales rose by nearly 11% in 2020 to nearly $18.3 billion. Frozen fruits and vegetables jumped 28.4% to $925 million. Canned fruits and vegetables increased 24.7% to $759 million. Dried beans, fruits and vege t abl es went up 18 . 1% to $503 million. Growth across all organic categories was constrained primarily by supply, Jasiello said, as “supply chains were caught off guard” from raw product to packaging to shipping capacity. Sales of organic nonfood products, which account for about 9% of total organic sales, reached $5.5 billion in 2020, “with some real winners in this category—and some struggles as well,” she said. For example, fiber—the larg- est segment in the nonfood catego- ry—experienced a “slow-growth year” of about 5%, as there wasn’t “much browsing in retail stores, not as many places to be and excuses to shop for new fiber items.” California continues to be “an or- ganic powerhouse,” she said, ranking No. 1 in the nation with 5,077 organic businesses. Some 90% of California shoppers buy organic, with commodity sales increasing 27% to nearly $3.6 bil- lion—36% of the U.S. total—from 2017 to 2019. The state boasts almost 20% of all organic acreage in the U.S., with 74% of its counties considered organic hotspots. Berries, chicken, milk, lettuce and grapes are the top organic crops in California, she noted. On the national level, Jasiello said the biggest policy challenge relates to the lack of movement to advance and

update organic standards at the U.S. Department of Agriculture. She cited a backlog of 20 different recommen- dations that have gone through the National Organic Standards Board that have yet to be implemented. “This will continue to harm the or- ganic sector as innovation and environ-

Water from the delta contributes to the water supply for more than two-thirds of Californiansand isusedto irrigatemillions of acres of farmland. Deltawaterdistricts,suchasCourchesne’s district, the Bryon-Bethany Irrigation District inContraCostaCounty, have some of the oldest water rights in the state—ri- parian and pre-1914 rights, in addition to a contract with the federal Central Valley Project. BBID’s post-1914 rights through theCVPwent froma 5%water allocation to zero. After last week’s adoption of curtail- ment regulations, he expects cutbacks to seniorwater rights. Chris Scheuring, California Farm Bureau senior counsel, in addressing the state water board last week, said, “Most of the (Delta) water rights holders discussed here have a face behind them—a farmer, farmfamily, farmworker or it couldbe just a person eating a salad. But there’s a face behind all of this, includingmy family.” “Ingeneral, farmersunderstanddrought and they understand lean rain years, but they don’t understand the downward

slide inwater reliability that we are facing inCalifornia,”Scheuring said. “At the same time, we’re watching the slow permitting of new storage and infrastructure projects and the failure to execute on what might get us out of these places called curtail- ment, things like Proposition 1.” Proposition 1, approved with wide vot- er support in 2014, was supposed to lead tomajor water storage projects to prevent crises in drought years. Work on getting these projects constructed has been slow. Back in the orchard in Brentwood, Courchesne is preparing for less water. He said he plans to continue farming sus- tainably by using micro-irrigation and regenerating the soil to build fertility and nutrients. He said he hopes this will help his trees bemore resilient and survive.

Hehas expanded the farmto280acres, specializing inpeach- es, plums, nectarines andother crops. Courchesne said he keeps farming be- cause “I love it. I get to work with nature, I get to be outdoors, and I work with great people.We’re that kindof a farmthat is in- tegrated into the community.” Noting that “farmers are cutting back their water use more than anybody else,” Courchesneunderscoredtheneedformore water conservationbyallCalifornians. “Everybodyhas todrink, everybodyhas

to take a bath and cook food, but we don’t have to water our golf courses and ceme- teries and lawns,” he said. “Millions of gal- lons go towaste every day becausepeople let their water run while brushing their teeth, so let’s not target the farmers.

Upon review of the previous admin- istration’s Navigable Waters Protection Rule done during the Trump administra- tion, the U.S. Environmental Protection Agency andU.S. Department of theArmy determined that that rule reduces clean water protections.

Pecan farmers test remedies to recharge aquifers Water seeps into an orchard in the San Joaquin Valley as part of test efforts to recharge aquifers with surface water captured during wetter winter months. A pilot program targets California pecan farms. A survey found that pecans were well-equipped to handle saturated soils.

ByDennisPollock Almond farmers in California have long been recharging depleted groundwater sup- pliesonsomeof theirmillionacres.Nownewinsights arebeing learnedas growersof a far smaller sister crop—pecans—are also capturing surfacewater inwintermonths in order to recharge underground aquifers. Pecan farms account for just 5,000 acres inCalifornia. But efforts by farmers to capture rainwater inwetterwintermonths and later flood their farms to reinvigorategroundwater supplies are offering new remedies to severe drought conditions.

The survey was conducted fromearlyMay tomid-June in 2019 and 2020. It found that pecans were able to tolerate saturated soils and floodingwell. No abnormalities, such as signs of bronzing or wilting, were observed, and there were no differences between trees in on-farm recharge treatments from those in a regularly irrigated treatment. Leaf analysis showed on-farm recharge either improved or had no effect on nutrient levels. Stemwater potential data indicated healthy trees. And yields were the same or higher in on-farm recharge plots compared to the regularly irrigated control and other nearby orchards in 2019 or 2020. Lowoxygenwas not detrimental to pecan tree health and yields. Additional benefits included salt flushing from the root zone and the ability to reduce irrigation. Bachand said recharge projects are being spurred in part by climate change, with less surface water stored in California’s snowpack and greater frequency and variability of drought and floods. Another stimulus is the Sustainable Groundwater Management Act and the fact that on-farmrecharge offers “new” water to help augment groundwater. “Water that currently flows out of an area in awet year can be captured in aquifers and that enhances flexibility,” Bachand said.

Asked about challenges to recharge, Cameron said those include providing theneeded infrastructureandconsidering soil differences and themovement of salts, pesticides and herbicides. “Management criteria have to be in place,” Cameron said. He and others also said challenges in- clude the difficulty of getting into flooded fields for treatments such as spraying. Cameron saidhe laser-leveled fields for even distribution of water. McKean said his almond trees are on high berms to control water flow, and he usesbothdripand flood irrigation. “It’snot real simple,” he said. McKean said he has concerns about plant health, and said he would like to see more research on rootstocks that might be best suited to recharge condi- tions. He said he would also like to see more research on leaching. King said timing is important inmanag- ing recharge. When water is available, he said, “you have to be prepared to take it.” King said he favors recharge because “it’s replicating natural systems.” McKean said he would like to see “credits” given to growers who use on- farm recharge.

In California, pecans are grown in 17 counties. The leaders inpecanproduction areTulareandColusacounties,withnearly half the acreage. One of the research plots had continu- ous flooding to maintain standing water. In another, there was alternate flooding between two sub-blocks, and in another there was regular irrigation followed by a second irrigation. A control plot had reg- ular flood irrigation. Poly pipe was stretched across about 850 feet of one field. It was fitted with ad- justablegates forwater flow. Terracingwas used to improvewater depth uniformity. Flooding did bring oxygen decreases in theroot zone, but recovery fromthatbegan immediately whenwater was off the field, Bachand said. Management techniques were to allow soils to dry briefly for five or sixdaysor toapply rechargewater toevery other row, then switch rows. The cost of recharge ranged from$35 to $200 an acre, about 1.5% to 9% of the cost of regular operations.

showed no significant effect on yield, and onwell-drainedsoils, largeamountsofwa- ter can be recharged. She said it is a viable option for regionswhere large amounts of excess water are less frequently available. “Flooding can create short-lived anoxic conditions in the root zone,” she said, add- ing that the duration of such conditions needs to be managed. Flooding reduces oxygen levels within the soil, inhibiting root respiration and root growth with po- tentially negative effects on crop yield. She added that winter recharge can produce nitrates in the root zone through mineralization of organic nitrogen and might reduce fertilizer needs during

the growing season. The most nitrate is leached within the first few hours of ap- plication, before conditions for denitri- fication are reached, and denitrification plays a greater role in fine textured soils with continuous flooding.

Is all salt bad?

The total salts in soil and water can come from several sources. Salts are often measured by the electrical conductivity (EC). The EC for irrigation water is normally a measure of total salts, but it does not tell us which salts make up the composition. Common units of measure are deciSiemens per meter (dS/m) or millimho per centimeter (mmho/cm), 1 dS/m = 1 mmho/cm. The EC is usually a balance of cations and anions reported as meq/l. Cations (+) Anions (-) Calcium Ca Bicarbonate HCO3 Magnesium Mg Carbonate CO3 Sodium Na The predominate cations and anions are listed above. Potassium may be reported but does not usually contribute to salinity issues. Boron and Nitrates may also be reported, these are important for diagnosing toxici- ties and N requirements. Irrigation water samples should be analyzed to tell us how much individual cations and anions are present. When EC measurements are above 4.0, and sodium levels are high, crops may experience reduced soil water availability for root absorption. Crops grown on saline soils must work harder to take up water. These crops may show symptoms of water stress, even when soils are moist. High levels of sodium in the water or soil can lead to poor soil structure decreasing water infiltration, damaging crops and increasing soil pH which changes nutrient availability. If leaching sodium with clean water isn’t an option, keeping calcium as the dominate salt will help reduce the negative effects of sodium. Remember to keep Ca > Mg + Na.

Researchers target fungus that attacks tree fruit, nuts

upper roots and tree crown is kept fairly moist through the entire growing season. “Most infected orchards have been found in the North Coast with fewer in the Sacramento Delta,” the guide- lines added. “Most affected orchards are on sandy loam to loam soils along streams or rivers originally lined with native oaks.” The disease can show itself as a grad- ual decline of trees in a circle extending out from the center or may result in the sudden collapse and death of trees that appeared for years to be healthy. The native oak root fungus pathogen is

already inmuch of California’s soil, even before susceptible tree fruit or nut crops are planted. “If an orchard is planted on a site where oak, black walnut or willow trees once grew, chances are very high that the inoculum already exists in the soil on old decaying roots,” according to the UC guidelines. Once an orchard is infested with ar- millaria, farmers can limit the spread by machinery or slow the damage through irrigationmanagement, but there is no re- liableway to rid ground of the pathogens.

ByBob Johnson Pear growers may be one step closer to having an answer for a widespread fungus that grows and survives for de- cades in wooded soils while waiting to attack tree fruit and nut crops with dev- astating impact. Armillaria, commonly known as oak root fungus, is a native pathogen that survives invisibly on deadwood and root material deep beneath the ground until new trees are planted, and then it can spread, causing wilt and decline. A recent University of California, Davis, study has developed protocols that will let researchers and plant breeders more quickly detect whether a pear rootstock is resistant to themost lethal strain of ar- millaria, at least in the lab. “There is no pear rootstock known to be resi stant to armi l lar ia,” said Carolina Tweedy, the UC Davis grad- uate student who adapted an in vitro technique for screening armillaria re- sistance in pear rootstocks. “This limits options for replanting trees in infected orchards. Due to the broad host range of armillaria, other tree crops face a similar challenge. In order to identify sources of resistance to be utilized in rootstock breeding programs, a rapid and reliable screening technique for pears is necessary.” Many pear varieties were considered resistant or at least tolerant of armillaria, but changes in irrigation practices may be creating conditions that encourage the disease. The switch from flood or furrow ir- rigation to sprinklers that keep the top of the soil and upper roots moist more often may be the reason armillaria has become more of an issue in pears in re- cent years.

“Armillaria root and crown rot most often occurs when the soil is cool and moist,” according to UC pear pest man- agement guidelines. “Recent infections of armillaria root rot in pear orchards may have been caused by a switch in irrigation practices from flood or fur- row irrigation to permanent under-tree sprinklers where water is applied more frequently and the soil layer close to the

personnel qualifications and training that haven’t been completed, some- times due to a lack of training records or other paperwork discrepancies, she said. Inspectors also recorded some health and hygiene compliance issues related to improper handwashing or ac- cess to facilities. Most noncompliance issues relate to record keeping, which Phillips said is “easily correctable and is not really going to lead to a large food safety issue.” Noting the program’s motto is “to educate before we regulate,” she said the program offers “a lot” of education and outreach to ensure farmers under- stand how to comply with the produce safety rule.

“We want this culture of food safety to become ingrained” in California farms, she added. Jeremy Johnson, chairman of the Cal i fornia State Organic Program Advisory Committee, said it is work- ing with the state to ease the adminis- trative burden on organic farmers so that there’s less paperwork. He said the committee has also been providing rec- ommendations to the state on how it can best use excess funds from organic registration to support organic. It has narrowed priorities to equity, education and research. Houston Wi l son, di rector of the Un i ve r s i t y o f Ca l i f orn i a Organ i c

Agriculture Institute, formed in 2020, said “a huge gap” remains in research for organic. Though research is need- ed in every area of production, he said the institute’s highest priority is pro- viding more effective crop nutrition practices, followed by weed, pest and disease management. With creation of the institute, Wilson said, California organic farmers will now have an addi t iona l resource to maintain their lead in the nation “while at the same time contributing to the economic viability and envi- ronmental quality of agriculture in this state.” (ChingLeeisanassistanteditorofAgAlert.

CCOF’s goal , she said, is to reach 30% organic farmland in the state by 2030, “because we believe organic can really offer solutions for climate resil- ience, economic security and health equity.” As the leading organic state, California currently farms about 10% of i ts land organical ly, she noted. Less than 1% of the nation’s land is farmed organically. Since the start of the CDFA Produce Safety Program in 2017, more than 430 California farms have been inspect- ed, with less than 20% of them organ- ic, said program Supervisor Shelley Phi l l ips. Organic farms “general ly have a good understanding of food safety,” she said. About a third of those inspected have gotten clean records, she said, although two-thirds are not in full compliance.
