California sources fertilizer via San Francisco Bay, Los Angeles, and Central Valley distributors; nitrogen from Trinidad-based LNG and liquid ammonia terminals; phosphate via Long Beach port.
| Driver | Impact |
|---|---|
| Crude oil prices | WTI crude is the primary cost driver; farm diesel tracks crude with a 6–8 week lag. |
| Refinery capacity | U.S. refinery utilization affects the diesel crack spread independent of crude prices. |
| Seasonal demand | Spring planting and fall harvest create regional price spikes of 5–10 cents per gallon. |
| Off-road vs. on-road | Dyed off-road diesel runs $0.10–$0.20/gallon below on-road retail; use where legal. |
