Old Rotation
Old Rotation[edit | edit source]
The Old Rotation is a historic agricultural experiment located in Auburn, Alabama. It is the oldest continuous cotton experiment in the world and the third oldest field crop experiment on the same site in the United States.
History[edit | edit source]
The Old Rotation was established in 1896 by the Alabama Agricultural Experiment Station director J.F. Duggar. The experiment was designed to study the effect of different crop rotation and fertilization methods on cotton yield.
Experiment[edit | edit source]
The Old Rotation experiment consists of 13 plots, each with a different combination of crops and fertilizers. The main crops grown are cotton, corn, and winter legumes. The experiment has provided valuable information on the benefits of crop rotation and the use of legumes to improve soil fertility.
Impact[edit | edit source]
The results from the Old Rotation have had a significant impact on farming practices in the Southern United States. The experiment demonstrated the importance of crop rotation and the use of legumes to maintain soil fertility, which has led to increased cotton yields and improved soil health.
Recognition[edit | edit source]
In 1988, the Old Rotation was designated as a National Historic Landmark by the National Park Service. It is also recognized as a historic site by the American Society of Agronomy.
