Experiment
The Old Rotation consists of 13 plots of six planting systems:
- A control test where cotton is planted without rotation or fertilizer
- Cotton rotated with winter legumes but not fertilized
- Cotton just fertilized
- Cotton rotated with corn and winter legumes
- Cotton rotated with corn, winter legumes, and fertilizer
- Cotton rotated with corn, winter legumes, and soybeans
After 110 years of continuous plantings, cotton yields remain high for the rotated plots, producing nearly three times the yield of the unrotated plots.
