Agricultural Patterns in U.S.: Livestock and Crop Distribution

This overview examines agricultural patterns in the U.S., focusing on livestock, particularly dairy and beef cattle, and crop distribution. It highlights how beef cows are widely dispersed, yet highly concentrated in feedlots, particularly in regions like Iowa. The crop patterns relating to climate are analyzed, with emphasis on major crops like corn, soybeans, and their rotation practices. The importance of nitrogen in this rotation is discussed, illustrating how corn utilizes soil nitrogen while soybeans enrich it, thereby enhancing soil quality.

  1. US Agricultural Patterns

  2. Livestock Patterns • Cows -- Dairy and Beef

  3. Notice how Beef cows are so widely dispersed.

  4. http://www.nal.usda.gov/awic/pubs/Beef/beef.htm

  5. But beef cattle in feedlots are more highly concentrated.

  6. What are you more likely to see in Iowa, cows or pigs?

  7. Crop Patterns • Climate of North America (US) • Corn, Soybeans, Sorghum, Citrus, Cotton, Wheat

  11. Does this match with your Act.K map?

  12. Why does this map of Soybeans so closely match the corn map?

  13. Corn – Soybean Crop Rotation • It’s all about the nitrogen—a critical element for all life • Corn draws nitrogen from the soil (and air) and it gets used and stored in the plant and especially the kernels. • Soybeans draw nitrogen from the air and store it in nodules in the root system. When the plant dies, that nitrogen remains in the soil.

  14. Does this match your Act.K map? (notice the next map)

  15. Notice the irrigation in western Kansas and Texas
