Farming in San Joaquin County, California

Broader context

Without reviewed regional crop guidance for California, the most reliable next step is the state's Extension service, which publishes crop, forage and livestock information for its own regions and can tell you what is commonly grown in San Joaquin County. The links below cover the essentials for any county.

• USDA NASS Quick Stats for crops historically produced in the county (statistics, not a suitability test)
• USDA plant hardiness map for winter cold limits on perennials (not annual crops)
• NRCS Web Soil Survey for mapped soils (a map is not a soil test)
• Crop and enterprise guides for what each enterprise needs from the land
