Req 8a4 — Major Crop Regions

Crops are not grown evenly across the United States. They cluster in regions where temperature, rainfall, soil, length of growing season, and transportation all line up in the crop’s favor.

Major Crop Patterns

Corn

The Corn Belt—especially Iowa, Illinois, Indiana, eastern Nebraska, and surrounding states—leads corn production. Deep prairie soils, warm summers, and enough rainfall or irrigation make this region ideal.

Cotton

Cotton is concentrated in the South and Southwest, including Texas, Georgia, Mississippi, Arkansas, and parts of the Carolinas and Arizona. It needs a long, warm growing season and does not tolerate frost well.

Forage crops

Forage is grown widely, but especially where livestock production is important: the Great Plains, upper Midwest, and irrigated western valleys. Hay, alfalfa, and pasture plants are tied closely to cattle and dairy systems.

Small grains

Wheat, oats, rye, and barley dominate parts of the Great Plains, the northern tier, and the Pacific Northwest. Dryland farming, cooler seasons, and broad open acreage favor many small grains.

Oil crops

Soybeans lead oil-crop production in the Midwest and eastern Corn Belt, often in rotation with corn. Canola is important farther north, where cooler conditions fit that crop better.

Why Regions Matter

Location is not just about weather. Successful crop regions also usually have:

• soil suited to machinery and root growth
• storage and processing facilities nearby
• rail, river, or road systems for moving harvests
• generations of local knowledge about the crop
