Understanding Corn Planting and Agronomy in the U.S.: A Historical Perspective

Each year, the United States plants approximately 85 million acres of corn, highlighting the importance of this staple crop. Agronomy, the science of crop production, encompasses soil science, pest management, and genetics to improve yields. The industry's evolution from small, animal-drawn farms to modern technology has significantly changed agricultural practices. Today, average farm sizes have increased from 146 acres in 1900 to 449 acres in 2007, reflecting advancements in farming techniques and equipment.
