Why Tracy Is a Farming Powerhouse
Tracy may be known today as a fast-growing commuter city linked to the Bay Area by Interstate 205 and the Altamont Corridor, but its roots run deep in agriculture. Located in southwestern San Joaquin County, the city is surrounded by fertile soil, a long growing season, and irrigation water delivered through the Delta-Mendota Canal and the California Aqueduct. That combination has made the Tracy area a reliable producer of almonds, walnuts, tomatoes, alfalfa, dairy, grapes, and specialty crops for generations.
The farming companies that thrive here balance tradition with innovation. Many are multi-generation family operations, while others are cooperatives that give growers access to national and global markets. Below are ten of the most respected farming and agricultural businesses connected to Tracy and the surrounding Central Valley, chosen for their reputation, community involvement, sustainability practices, and contribution to the regional economy.
1. Dell'Osso Family Farm
Based just north of Tracy in Lathrop, Dell'Osso Family Farm is a multi-generation operation best known for its fall pumpkin maze and family attractions. Behind the seasonal fun is a working farm that has cultivated crops in San Joaquin County for decades. The farm has become a model for agritourism, showing how growers can diversify revenue while teaching thousands of visitors each year about where food comes from.
2. Van Groningen and Sons
Operating in the Manteca and Tracy area, Van Groningen and Sons is a respected family farm that grows a variety of crops, including its well-known sweet corn and seasonal pumpkins. The family is recognized for direct-to-consumer farm stands and for building strong relationships with local shoppers. Their success highlights the demand for fresh, locally grown produce among Tracy households.
3. Delicato Family Wines
Headquartered in nearby Manteca, Delicato Family Wines is one of the largest family-owned wine companies in the United States. Its roots trace back to a small vineyard planted in the 1920s, and the company now farms extensive vineyard acreage across California. Delicato represents the economic importance of viticulture to San Joaquin County and invests heavily in sustainable farming practices.
4. Blue Diamond Growers
Blue Diamond Growers is a grower-owned almond cooperative with thousands of member farmers across California, many of them in San Joaquin County.

Blue Diamond is widely respected for product innovation and for supporting orchard research.
5. Diamond of California
With deep ties to Stockton, Diamond of California is a leading name in walnuts and culinary nuts. Walnut orchards are a familiar sight along the roads outside Tracy, and the brand has long worked with regional growers to bring their harvest to grocery shelves nationwide. Its focus on quality control and consistent supply makes it a key partner for nut farmers in the area.
6. Pacific Coast Producers
Pacific Coast Producers is a grower-owned cooperative headquartered in Lodi that processes canned fruits and tomatoes. Its member-growers farm across the Central Valley, and the cooperative model allows family farms to share in the value of finished products. The organization is known for stable relationships with growers and for supplying private-label grocery products across the country.
7. The Morning Star Company
The Morning Star Company is one of the largest tomato processors in the world, with facilities in the Central Valley. Processing tomatoes are a major crop in San Joaquin County, and Morning Star contracts with many local growers during the busy summer harvest. The company is also known for its unique self-management business philosophy and highly efficient operations.
8. Leprino Foods
Leprino Foods operates a large cheese manufacturing facility in Tracy, making it one of the most visible agricultural employers in the city. While Leprino is a processor rather than a farm, its presence supports the dairy farms of the region by providing a dependable market for milk. The plant also provides hundreds of local jobs and anchors Tracy's food manufacturing sector.
9. California Dairies Inc.
California Dairies Inc. is a farmer-owned dairy cooperative representing a large share of the state's milk production. Many of its member families operate dairies throughout San Joaquin County.

10. Sunsweet Growers
Sunsweet Growers is a grower-owned cooperative famous for prunes and dried fruit. Although headquartered farther north in Yuba City, its network includes orchard growers across the Central Valley. Sunsweet stands out for its marketing strength, rigorous quality standards, and long history of supporting farm families who rely on tree fruit crops.
Trends Shaping Farming Around Tracy
Water management remains the top issue for Tracy-area farmers. Many operations have adopted drip and micro-sprinkler irrigation, soil moisture sensors, and satellite-based crop monitoring to make every acre-foot count. Sustainability certifications are also growing in importance, as buyers and consumers increasingly want proof of responsible land and water stewardship.
Another major trend is diversification. Agritourism, farm stands, and direct-to-consumer sales help family farms capture more value, while cooperatives help growers absorb market volatility. Urban growth in Tracy also creates pressure on farmland, which makes efficient, high-value production more critical than ever.
How to Evaluate a Farming Partner
Whether you are a buyer, investor, job seeker, or fellow grower, look for companies with a long operating history, transparent sustainability practices, strong grower relationships, and a visible commitment to the community. The businesses listed above meet those standards and illustrate why the Tracy region continues to feed California, the nation, and the world.
