The South Plains is, according to Texas A&M, the largest cotton producing region in the world with up to 3 million acres in cotton a year. Cotton is either irrigated and you’ll see the large center pivot irrigation systems in the fields. Or dry land farmed, without irrigation. Cotton needs warm soil to germinate and a long growing season of frost-free days, ideal for this area. Other major crops you’ll notice if you’re out and about are peanuts, corn, grain sorghum, and wheat.
