How are you celebrating American agriculture in your life? In advance of National Ag Week, March 19-25, and National Ag Day, March 21, Central Valley third-grade students were “learning with lettuce” how to bring more agriculture into their lives last week. The UC Kearney Agricultural Research and Extension Center offers the free lettuce plantings every year at Farm and Nutrition Day in Fresno County and Kings County, typically around the time of National Ag Week.
Students with the help of volunteers learned how to plant tiny lettuce seedlings into a pot of healthy soil to take home for transplanting later. In addition to helping the students connect their food to agriculture, the lettuce planting offered an engaging, hands-on experience growing healthy and nutritious food at home.
National Ag Week is a nationwide effort coordinated by the Agriculture Council of America to tell the vital story of American agriculture and remind citizens that agriculture is a part of all of us. National Ag Day encourages every American to:
• Understand how food and fiber products are produced.
• Appreciate the role agriculture plays in providing safe, abundant and affordable products.
• Value the essential role of agriculture in maintaining a strong economy.
• Acknowledge and consider career opportunities in the agriculture, food and fiber industry.
Each American farmer feeds about 144 people. As the world population soars, there is even greater demand for the food, fiber and renewable resources produced in the United States. Agriculture is this nation's #1 export and incredibly important in sustaining a healthy economy. That's why National Ag Week is a great time to reflect on and be grateful for American agriculture.
Grocery shopping can be the most anticipated or the most dreaded necessity of daily life. A trip to the market can end with a smile over the thrill of victory from finding great bargains or end with a frown from the agony of defeat over budget anxieties. For most of us, budget is the primary factor in our food experiences. Low budget or no budget is often the culprit that leads to unhealthy food choices.
University of California 4-H Food Smart Families program with the UC Kearney Agricultural Research and Extension Center, teens from Parlier High School in Fresno County are teaching Parlier youth ages 8-12 how to get around budget roadblocks on the path to healthy eating. The program uses a “Teens as Teachers” approach, with teens educating younger youth through a series of hands-on, interactive nutrition lessons after school.
Food connections to local agriculture are highlighted through the partnership with the UC Kearney Agricultural Research and Extension Center. The center will host agriculture tours and family nutrition education activities at a Wellness Fair later this month to wrap up the program.
According to recent United States Department of Agriculture studies, nearly 16 million children live in households where they do not have consistent access to food throughout the year.
UC 4-H Food Smart Families empowers families through food knowledge and education to build sustainable solutions that confront food insecurity and improve health. Youth are engaged at a critical age for growing skills and establishing behaviors today that become sustainable, healthy habits for their families and communities tomorrow. Youth learn they can prepare food themselves and parents learn about working together as a family to plan healthy meals.
Thoughtful discussions, and sometimes passionate debates, ranging from whole grain pasta versus whole wheat pasta to the tasty virtues of hummus, mixed with youthful laughter. The teens were pleasantly surprised to discover they had additional budget to spare. Return trips were made to the produce department for more fruit, vegetables and even hummus.
Comments from the teens told the story of their success. “Now I know what my mom has to go through when she's shopping for food,” and “Look at my cart. Food Smart Families is really influencing me!” Who knew grocery shopping could be so much fun?
The USDA Center for Nutrition Policy and Promotion offers these 10 tips for affordable vegetables and fruits:
• Use fresh vegetables and fruits that are in season.
• Check your local newspaper, online and at the store for sales, coupons and specials.
• Plan out your meals ahead of time and make a grocery list.
• Compare the price and number of servings from fresh, canned and frozen forms of the same vegetable or fruit.
• Buy small amounts more often to ensure you can eat the foods without throwing any away.
• For fresh vegetables or fruits you use often, a large size bag is the better buy.
• Opt for store brands when possible.
• Buy vegetables and fruits in their simplest form.
• Start a garden for fresh, inexpensive, flavorful additions to meals.
• Prepare and freeze vegetable soups, stews or other dishes in advance.
UC Cooperative Extension and Agricultural Experiment Station researchers are working with growers on fertilizer management, irrigation efficiency and other farming practices to provide options for protecting groundwater, which serves as a primary drinking water source for many rural communities. The following are some examples of ANR research and extension projects under way. The scientists’ names are hyperlinked to their contact information.
Quick nitrate test guides fertilizer management
Michael Cahn and Richard Smith, UC Cooperative Extension advisors in Monterey County, and Tim Hartz, UCCE specialist in the department of Plant Sciences at UC Davis, have developed a quick test to measure soil nitrate in the field so growers can match fertilizer rates with plant needs. The test has reduced nitrogen-loading rates by an average of 70 pounds per acre in lettuce. On-farm demonstration trials have shown that by testing the soil, growers can reduce their fertilizer use by about 30 percent. Major growers in Monterey County, who manage a significant number of vegetable acres in the Salinas Valley, have begun using the quick nitrate test in their operations. For more information read the summary article on p. 5 and fine tuning article on p. 12 of Crop Notes.
Assessing plant nutrient status
Leaf sampling is a common method of determining when a nut tree has a nutrient deficiency. Patrick H. Brown, professor in the Department of Plant Sciences at UC Davis and Agricultural Experiment Station pomologist, and his colleagues are studying other ways of assessing plant nutrient status to help almond and pistachio growers manage fertilizer applications with more precision. For more information, see Crop Nutrient Status and Demand.
NBOT aids dairies in nutrient planning
The Nitrogen Budget Optimization Tool (NBOT) is a planning tool being developed for dairies by David Crohn, professor and UC Cooperative Extension specialist in the Department of Environmental Sciences at UC Riverside. NBOT is an algorithm that uses a daily time step to represent crop nitrogen demand, nitrogen mineralization and losses from leaching, denitrification and ammonia volatilization. Typical nitrogen application charts tell how much nitrogen a crop needs during the growing season, but they do not say when the crop will need it. With NBOT, dairy operators input information about the crop they are growing, how much they expect to harvest and when they can apply manures. NBOT’s output gives an idealized management strategy that helps dairy operators decide what they should do all year round.
N-Ledger software addresses nitrogen management
A software program under development by a team headed by Marsha Campbell Mathews, UC Cooperative Extension advisor in Stanislaus County, will help dairy operators and other farmers improve nitrogen management by calculating when nitrogen applied in manure is expected to be released from organic form into a form that the crops can use. Nitrogen applications are tracked, release rates are estimated and adjusted for expected losses, and the calculated total is compared to the expected daily crop need for nitrogen. The program helps the user choose an application strategy that will meet the crop’s needs and result in the least possible amount of nitrate in the soil during periods when it is vulnerable to leaching or other losses. For more information, see the UC Cooperative Extension in Stanislaus County Manure Nutrient Management website.
Adjusting field length can reduce irrigation levels
In his research on how dairy operators can reduce water applications to their crops, Larry Schwankl, UC Cooperative Extension specialist at Kearney Agricultural Research and Extension Center in Parlier, has found that allowing less water to percolate will reduce impacts on groundwater. With shorter furrows, water applied per acre was cut nearly in half. In addition, manure water is often added to fresh water as part of dairy irrigation and fertigation practices, so being able to reduce the applied water also significantly reduces the amount of nitrogen applied. For more information, see Schwankl's Irrigation Management website.
UC helps dairy industry manage nitrogen on the farm
It is common practice for dairy operators to use cattle manure as fertilizer for their silage crops. UC Cooperative Extension advisors throughout California routinely provide reliable information to dairy operators and consultants so they can efficiently manage nitrogen on the farm and comply with pending state regulations. This information includes how to install and calibrate flow meters, how to measure nitrogen levels in manure ponds, how much nitrogen crops need and when they need it, and how to properly sample the crops that are harvested to know how much nitrogen is being removed. “We’ve developed protocols to ensure accurate information gathering, and we can share these with the dairy industry,” said Carol Frate, UCCE advisor in Tulare County. For more information, contact a UC Cooperative Extension dairy advisor.
