One doesn't need to be a seasoned farmer to know that growing conditions in Canada are completely different than those found in the low desert of California.
And yet, for many years, studies conducted in Canada were used to generate nitrogen uptake data for the California carrot production system, so growers managed their fields based on their own experiences – and that research conducted thousands of miles to the north.
Carrots had been among the crops grown in California that did not have site-specific data to suggest the best source, rate, timing and placement of nitrogen, in the highly variable cropping seasons and locations throughout the state. That's why new information – based on local research and published in August – is invaluable to farmers in Imperial and Kern counties, where the majority of the carrots in California are grown.
Two years of data from two experimental trials at UC Agriculture and Natural Resource's Desert Research and Extension Center – as well as from 10 commercial fields – produced key recommendations for farmers to make the most of their irrigation and nitrogen applications.
“The point is we developed information in your field, based on your practices, your climate, your production system – and this is what is really happening,” said Ali Montazar, UC Cooperative Extension irrigation and water management advisor for Imperial County. Montazar conducted the study alongside Daniel Geisseler, UCCE nutrient management specialist at UC Davis, and Michael Cahn, UCCE irrigation and water resources advisor for Monterey County.
With reliable data gathered under real-world conditions, Montazar said growers now have solid reference points for when – and at what rate – to irrigate and apply fertilizers in the low desert environment. One of the key findings, for example, was that the carrots' nitrogen uptake is generally low in the first 40 to 50 days, so growers are advised to limit their fertilizer application during that period.
Then, by tailoring those basic guidelines to their own site-specific situation and optimizing their practices, growers can maximize the amount of nitrogen taken up by the carrots – and minimize the amount that is leached out.
“Improving irrigation and nutrient management in the desert production system is what local growers are themselves trying to achieve. With improving efficiency and reducing nutrient leaching, we can improve the quality of water in the Salton Sea,” said Montazar, noting the longstanding challenges of reducing contaminants from irrigated lands to protect its unique ecosystem and wildlife.
While contamination of groundwater is not a critical issue in the desert, the best practices in this study can also help carrot growers in parts of California where nitrogen leaching into groundwater and drinking water supplies is a greater concern.
Montazar is currently leading a team in studying carrot-growing management practices under slightly different conditions in Kern County, with the hopes of publishing findings in late summer 2022.
The Imperial County study, “Spatial Variability of Nitrogen Uptake and Net Removal and Actual Evapotranspiration in the California Desert Carrot Production System,” is published in the journal Agriculture, and can be found at https://doi.org/10.3390/agriculture11080752. Findings and recommendations also appear in Progressive Crop Consultant: https://progressivecrop.com/2021/09/new-knowledge-based-information-developed-to-enhance-water-and-nitrogen-use-efficiency-in-desert-fresh-market-carrots/.
Funding for this study was provided by the California Department of Food and Agriculture's Fertilizer Research and Education Program, as well as the California Fresh Carrots Advisory Board.
The COVID-19 pandemic hit farmers hard. Supply chains were disrupted and even non-traditional agritourism revenue streams such as hay mazes and on-farm events had to be canceled due to shelter-in-place mandates.
On the other hand, demand for local farm products skyrocketed, and thus many farmers and ranchers needed a quick pivot strategy and a set of new skills.
UC Sustainable Agriculture Research and Education Program (SAREP) was well-positioned to support this shift toward direct sales, pulling in trusted community partners and experienced farmers and ranchers to put together a comprehensive webinar series, “Agritourism and Direct Sales: Best Practices in COVID Times and Beyond”.
Funded by a USDA Farmers Market Promotion Program (FMPP) grant, the webinar series is part of a three-year project, Strengthening California Local Food Networks with Agritourism and Direct Sales, which provides trainings and technical assistance to farmers and ranchers on how to diversify their revenue streams.
The strength of the series, which includes eight webinars that were recorded earlier this year and are available online, lies in the collaborations among the UC SAREP Agritourism Program, UCCE, community groups, and farmers and ranchers.
The series features a range of speakers, including representatives from community organizations, technical experts, academic researchers, and farmers – all coming together to build resilience and adaptability for small-farming operations and the agritourism industry across California during the pandemic and after.
“It's great to collaborate with other organizations and regions, to learn from each other and to broaden our networks, as we are all working to create more resilient and sustainable food systems,” said Carmen Snyder, executive director of Sonoma County Farm Trails, one of the nonprofit partners on this project.
And because of those strong partnerships, the webinar topics reflected the on-the-ground needs facing agricultural producers.
“COVID initially dramatically affected farmers' restaurant contracts, with many losing more than 80% of their accounts overnight,” Snyder said. “CSAs [Community Supported Agriculture], on the other hand, couldn't keep up with the demand, and all of our CSA members were full and had wait lists for the first time ever. Producers pivoted by creating more online stores, including pick-up and delivery options. It was a challenge for them to navigate the new technology and platforms.”
The “Online Sales Options and Methods” webinar, a partnership with the Community Alliance with Family Farmers (CAFF), provided an overview of several e-commerce marketing and online sales strategies that farmers can implement to diversify their revenue pathways and reach new customers. CAFF stressed the importance of farmers enhancing their resiliency through e-commerce.
The webinar also featured Ciara Shapiro, the owner of AM Ranch in Penn Valley, who shared her experience with online marketing and how it helped her and her husband survive the pandemic when the restaurants and farmers markets they sold to shut down. This personal and informative webinar demonstrated the effectiveness of online sales and marketing, while highlighting available resources from groups like CAFF.
The “Safe, Healthy and Successful Farm Stands” webinar was aimed at farms of all sizes and organizations that operate or advise agricultural operations using farm stands as a form of revenue. The webinar provided an outline of the rules and regulations that farm stand operators needed to follow during COVID – as well as during business-as-usual times.
Both farmers saw an increase in farm stand business during the pandemic, which Yagi attributed to the “traffic storm of people” who attended their annual plant sale fundraiser and came to participate in new farm outdoor activities and volunteer opportunities. Yagi also noted the growing number of low-income individuals who were unable to access fresh produce during the pandemic.
The speakers' shared experiences running successful farm stands gave audience members tangible examples and real-time information on how to incorporate farm stands into their businesses.
Carmen Snyder of Sonoma County Farm Trails, which helped circulate the recorded webinars to their network of farmers and ranchers, remarked: “These webinars were extremely helpful for local producers, to get clarity on best pandemic practices during these challenging times and to learn how other producers are adapting and navigating the circumstances.”
My father was ahead of his time.
Years before Americans were asked to, Jim Hayden ensured that our family conserved energy by keeping the thermostat low, turning off lights and taking "military" showers to reduce water use. My father also observed the speed limit. Our family vacations took us to national parks. I grew up with a keen appreciation for the outdoors. I remember the sense of horror and helplessness when I saw the images of distressed wildlife in the aftermath of the Santa Barbara oil spill, which devastated the beaches that were an important part of our family's life.
In part as a result of that oil spill, Earth Day came into being. And 49 years after that inaugural Earth Day event, many of us will find ourselves at a gathering dedicated to increasing awareness of the environment that supports and sustains us all.
History of Earth Day
Earth Day was launched in 1970. Many factors contributed to the call for a national day focusing on environmental stewardship, including the publication of Rachel Carson's Silent Spring - serialized in the New Yorker - and the catastrophic oil spill that occurred off the coast of Santa Barbara in 1969. The Santa Barbara oil spill galvanized U.S. Senator Gaylord Nelson (D-Wisconsin) to call for a national day of locally inspired and organized "teach-ins" on the environment - a national "Earth Day." The Earth Day model was inspired by the spirit of campus activism at the nation's colleges and universities. It wasn't top-down, but rather a grassroots effort that encouraged communities to develop educational and service events around issues and topics important to them.
Earth Day struck a chord; some estimates suggest that 1 in 10 Americans participated in the first events. Earth Day is widely credited with "sparking" the modern environmental movement. Landmark environmental legislation swiftly followed (including the Clean Air Act, Clean Water Act and Endangered Species Act). The Environmental Protection agency was founded that same year. Twenty years after its launch, Earth Day became a global movement.

UC ANR research efforts support a healthy and sustainable environment
UC ANR is dedicated to supporting a healthy and sustainable environment. It's part of our core mission. Highlighted below are just a few of the many projects we're working on to protect California's natural resources, build climate-resilient communities and ecosystems, and promote healthy people and communities.
Seeking Street Trees that Can Cope With Climate Change
Trees play a vital role in shading and beautifying California's urban areas. UC ANR researcher Janet Hartin says that:
“Urban areas create heat islands, with dark asphalt surfaces reradiating heat. Cities can be 10 to 20 degrees warmer than the surrounding environment."
Trees provide other benefits, including improving soil health and stability, providing habitat for wildlife and serving as a source of beauty. But climate change (resulting in reduced rainfall and higher temperatures) can create chronic stress in some street tree species.
To find a solution, UC Cooperative Extension scientists are partnering with the U.S. Forest Service "in an unprecedented 20-year research study to expand the palette of drought-adapted, climate-ready trees for several of the state's climate zones."
“The idea is to look at available but under-planted, drought-tolerant, structurally sound, pest resistant trees for Southern California that do well in even warmer climates,” said Janet Hartin, UCCE horticulture advisor in San Bernardino County.

CDFA and UC ANR join forces to advance Climate-Smart Ag
A new partnership between the California Department of Food and Agriculture (CDFA) and UCANR aims to advance climate-smart ag in California. More than $1 million has been used to hire 10 UC Cooperative Extension community education specialists, who are being deployed to 10 counties to help farmers participate in CDFA programs that increase the adopting of "smart" farming and ranching practices.
The primary focus is putting into action on-farm solutions to improve (and increase) smart farming practices that reduce greenhouse gas emissions. Practices that improve soil health, nutrient management, irrigation management, and more will be emphasized.

Be kind to the Earth by reducing food waste
Nearly 40 percent of the food produced in the U.S. is wasted and much of that waste ends up in landfills (definitely not good for our environment or the economy). The National Resources Defense Council estimates that the average family of four throws out nearly 1,000 pounds of food each year, wasting roughly $1,500. Consumers as a group waste more food than farms, grocery stores or restaurants. For tips on ways you can reduce #FoodWaste, click here.

The above photo is one of my favorites. It was taken by Apollo 8 astronaut Bill Anders on Dec. 24, 1968, while in orbit around the moon. It shows the Earth rising for the third time above the lunar horizon. It always serves to remind me that my individual actions do matter, and when considered with the actions of others, contribute to real change ... the "moon shot." Have a great Earth Day!/h3>/h3>
When people don't think about the impact of their decision-making on others, it can ultimately lead to tragedy - the tragedy of the commons, said UC Agriculture and Natural Resources researcher Mark Lubell during an interview on Jefferson Public Radio. Lubell, director of the Center for Environmental Policy and Behavior at UC Davis, studies human decision-making in the context of the environment.
"People think about what happens on their private land and make their private decisions, but they don't think about how their private decisions affect others," Lubell said. "You see this all the time with human decision-making."
An example he uses with his students is how they and their roommates manage their shared kitchens.
"When one person's dishes pile up, it impacts the others," Lubell said. "I ask how they would make rules to solve the problem."
Lubell said the parties need to collectively develop a policy that is mutually beneficial.
"If we didn't have that capacity, we would be in big trouble," Lubell said.
Cooperation tends to be the norm, however the media is more likely to cover cases of conflict, so they tend to get more attention.
Citizen science is really picking up steam with the White House honoring 12 “Champions of Change” for their dedication to increasing public engagement in science and science literacy and the recent launching of a new Citizen Science Association. This year the momentum continues and everyone will be able to celebrate the first national Citizen Science Day on April 16, 2016, when the Citizen Science Association and SciStarter will promote and inspire organizations around the country to host events in celebration of public participation in scientific research. A major celebration will be held in conjunction with the USA Science & Engineering Festival in Washington, DC. This will kick off a series of citizen science open houses and activities to be locally sponsored by science centers, museums, libraries, universities and schools, and federal agencies nationwide.
What is “citizen science” exactly? Citizen science involves engaging non-professionals in scientific research. While applied across many disciplines of science, including biochemistry, astronomy, and psychology, UC Agriculture and Natural Resources' California Naturalist Program (CalNat) specifically empowers participants and partners to use citizen science to inform natural resource management. To understand and protect natural resources, scientists and decision makers often need information over long time periods and across many locations. Citizen science is one crowd-sourced
The CalNat Program has incorporated citizen science in the training curriculum from the program's inception. One of the program's primary goals is to increase public participation in natural resource conservation and citizen science projects throughout the state. Each partnering organization offering a CalNat certification course must adopt a class citizen science project so that each course participant gains experience in data collection and entry. Course participants are introduced to the interactive, on-line iNaturalist tool, where users can record observations from nature, develop online species lists and journals, meet other naturalists, and contribute to research-grade observations at the Global Biodiversity Information Facility. While some partner organizations already have an active
Together, with the Alliance of Natural Resource Outreach and Service Programs (ANROSP), we anticipate celebrating the first national Citizen Science Day on April 16 with our 16 scheduled spring California Naturalist courses and the 26 other Naturalist programs around the nation.
California Naturalists contribute to a variety of citizen science projects.
