U.S. interstate food shipments rely on regional climate advantages and scale. Here's a snapshot of major crops moving from field to fork across state lines.
Top shipped: Grapes (table & wine), almonds, strawberries, lettuce, broccoli, tomatoes, oranges, avocados. Mediterranean climate + massive irrigation = year-round harvests feeding all 50 states.
Iowa: #1 in corn, #2 in soybeans. Mostly feed, ethanol, processed ingredients.
Nebraska: #3 corn, #4 soybeans, plus significant wheat. Rail networks move grain to Gulf export terminals and domestic processors.
Leads in hard red winter wheat (bread flour). Soybeans rising. Unit trains haul grain to millers nationwide.
Historic tobacco leader (though acreage declining). #1 in sweet potatoes—shipped fresh and processed year-round.
Top cotton producer; massive hay/alfalfa output for dairy/beef operations across the South and Southwest.
Lake-effect climate yields #1 tart cherries, top-5 apples. Fresh and processed (juice, pie filling) ship nationally.
Oranges (mostly juice), grapefruit, tangerines. Despite citrus greening disease, still dominant U.S. fresh-citrus source Nov–Jun.
Infrastructure (rail, barge, refrigerated trucking) and federal grading standards enable this coast-to-coast produce flow.
