New UC study estimates costs for growing coastal organic strawberries
A new study that can help growers and other readers estimate costs and potential returns for Central Coast organic strawberries was recently released by UC Agriculture and Natural Resources, UC Cooperative Extension and the UC Davis Department of Agricultural and Resource Economics.
“This study provides growers with a baseline to estimate their own costs, which can help when applying for production loans, projecting labor costs, securing market arrangements, or understanding costs associated with water and nutrient management and regulatory programs,” said Brittney Goodrich, UC Cooperative Extension specialist and study co-author.
The cost study models a management scenario for a 30-acre farm, 27 acres of which are planted to organic strawberries. The remaining acres are for the irrigation system, roads, and buildings. The study describes the cultural practices used in organic strawberry production and harvest, including land preparation, soil fertility and pest management, irrigation and labor needs.
The 20-page study shows costs for each operation, material inputs and costs, and cash and non-cash overhead costs in a variety of formats for one production and harvest cycle. A ranging analysis is also included and shows potential profits or losses over a range of prices and yields.
The new study, “2024 Sample Costs to Produce and Harvest Organic Strawberries,” can be downloaded from the UC Davis Department of Agricultural and Resource Economics website at https://coststudies.ucdavis.edu.

A U.S.-China trade war would cost California farmers
Loss of China's preferred trade status could hurt crop, dairy and livestock exports
The Biden administration recently announced large, increased tariff rates for Chinese electric vehicles, solar cells, semiconductors, and aluminum and steel products. This raises the possibility of another trade war with China that could impact agriculture.
Economists from UC Davis and North Dakota State University evaluated the potential implications of the U.S. revoking China's Permanent Normal Trade Relations (PNTR) status. They found that if China retaliated against a change in China's PNTR status, it could lead to a 9.5% increase in China's agricultural import tariffs, resulting in potential trade losses to California agriculture of around $1 billion annually.
California agriculture was hit hard by the 2018-19 trade war with China, and many industries have still not recovered from its effects. Despite this, there is increasing support in Congress for further restrictions on trade with China, with proponents asserting that China is not complying with the World Trade Organization's regulations.
The authors' research suggests that some product groups – such as horticultural products, dairy, livestock and meats – would likely experience even steeper than average increases in import tariffs.
“The impact on import tariffs for non-agricultural sectors would be even larger, with the average import tariff going up from 3.9% to 32.5%,” said co-author of the study Colin A. Carter, Distinguished Professor in the Department of Agricultural and Resource Economics at UC Davis.
For all California agricultural exports, they estimated an average decline in export value between 28.4% and 34.8% when comparing a scenario where China's PNTR status is revoked to one where it is not. This translates into an estimated trade loss of between $800 million and $1 billion, using 2023 California agricultural exports. Some crops that rely heavily on China for exports, such as tree nuts, would be more severely impacted by these effects, particularly considering that some of them are still subjected to residual tariffs from the 2018-19 trade war.
The last trade war between the United States and China led to significant decreases in crop prices and lost export opportunities. As co-author Sandro Steinbach, Associate Professor in the Department of Agribusiness and Applied Economics and the Director of the Center for Agricultural Policy and Trade Studies at North Dakota State University notes, “Once access to a market is lost, gaining it back is difficult, as the 2018-19 trade war has shown.”

New UC study estimates blackberry production costs
A new study that can help growers and other readers estimate costs and potential returns for blackberries grown on California's Central Coast was recently released by UC Agriculture and Natural Resources, UC Cooperative Extension and the UC Davis Department of Agricultural and Resource Economics.
“The study provides growers with a baseline to estimate their own costs, which can help when applying for production loans, projecting labor costs, securing market arrangements or understanding costs associated with water and nutrient management and regulatory programs,” said Brittney Goodrich, UC Cooperative Extension specialist and study co-author.
The cost study models a management scenario for a 30-acre farm, 15 acres of which are planted to blackberries. The remaining acres are planted to other berries or are used for the irrigation system, roads and buildings. The authors describe the cultural practices used for the establishment, production and harvest of blackberries, including land preparation, soil fertility and pest management, irrigation and labor needs.
The 28-page study shows costs for each operation, material inputs and costs, and cash and non-cash overhead costs in a variety of formats for an establishment year and then four additional production years. A ranging analysis for the four production years is also included and shows potential profits or losses over a range of prices and yields.
The new study, titled “2024 Sample Costs to Establish, Produce and Harvest Blackberries” can be downloaded from the UC Davis Department of Agricultural and Resource Economics website at https://coststudies.ucdavis.edu.
For a detailed explanation of the assumptions and calculations used to estimate the costs and potential returns, readers can refer to the narrative portion of the study.
Sample cost of production studies for many other commodities grown in California are also available on the website.

Grape seeds, stems and skins can reduce dairy cattle emissions
Low-cost wine industry additive also improved feed efficiency and milk quality
Researchers at University of California, Davis, added fresh grape pomace left over from winemaking operations to alfalfa-based feed for dairy cows and found that methane emissions were reduced by 10% to 11%.
The preliminary findings could offer a low-cost sustainable pathway for vineyards to reduce waste while helping dairy operations maintain quality while cutting back on emissions of methane, which is a powerful greenhouse gas.
“This is the first time anybody has shown that this can work in California,” said Ermias Kebreab, an animal science professor and associate dean of global engagement at UC Davis. “You're reducing emissions, you're improving the quality and it may also reduce the cost of production.”
The pilot research project, which will be detailed in a paper later this year, also found that mixing in grape pomace improved feed efficiency and increased healthful fats, said Selina Wang, an associate professor of Cooperative Extension in small scale fruit and vegetable processing.
“We found that the feed with the additive of grape pomace changed the fatty acid composition of the milk and, in particular, increased the polyunsaturated fats, which are the main fats in grape pomace,” Wang said. “This suggests that supplementing the feed with an optimal fatty acid profile may have positive impact on the fatty acid profile of the milk and increase their health benefits.”
Symbiotic commodities?
In 2022, California was the leading dairy producer in the country, generating $10.40 billion in sales, while 90% of wine production came from the Golden State, with a market value of $5.54 billion.
Processing grapes for wine generates thousands of tons of waste in the form of grape pomace, which consists of leftover seeds, skins and stems. Dairy and livestock are responsible for more than half of the state's methane emissions, owed largely to cow burps.
They are the top two agricultural commodities in California, according to state production statistics, and reducing waste and emissions for both industries are key to the state meeting its climate goals.
Tannins for emission reductions
Wine grapes are high in fats and tannin, which is known to reduce methane emissions, so Kebreab sought to test if adding grape pomace to feed could have a positive effect while not adversely affecting production.
“It's a byproduct that's not being used much,” he said. “This is something that can be included in our efforts to try to reduce emissions.”
A mix of feed options
To do the research, scientists worked with Holstein dairy cows and gave the animals feed consisting of alfalfa, wheat, almond hulls, cottonseed and grain. After two weeks, the cows were split into three groups: A control group with no change in diet, another where the feed combination included 10% grape pomace and a third that received 15% grape pomace.
Every four weeks, the cow groups would change feed combinations.
They were fed twice daily by postdoctoral students and interns, and emissions were monitored daily. Milk production was documented in the morning and evening and milk samples were collected weekly to analyze for fat, protein, lactose and other measurements, which showed no differences between the control and other groups.
Methane and hydrogen emissions were reduced compared with the control group, suggesting that grape pomace reduced enteric emissions without affecting production.
“I think the dairy industry will be very interested in this,” Kebreab said. “Sometimes when you're using additives, they have palatability issues. With grape pomace, they absolutely love it.”
Next on the list is a trial with olive pomace and working to understand the mechanism that reduces emissions. “If we have a better understanding of the mechanisms, we can select the feed additive or a mix of feed additives to reduce dairy cattle emissions and make dairy milk healthier while making use of the agriculture byproducts,” Wang said. “There's a lot of room to grow in this space and we're excited about this work.”
The research was supported by the California Dairy Research Foundation.
