Humboldt and Gibson County enjoy one of the best-diversified economies in the MidSouth. Farmers in the County pioneered the switch from cotton, corn and tobacco to truck farm crops such as strawberries, cabbage, and tomatoes, and have become one of the nation's major suppliers of vegetable seedlings. To match this, Humboldt's local plants produce commercial bakeware, soda fountain products, mop yarns, high temperature material for molten metal, electric motors, corrugated boxes, metal stampings, golf balls, axle housings, children's clothing, non-dairy cheese products, load tap changers and components for bath and kitchen cabinets.
