The Cullars Rotation Experiment (circa 1911) is the oldest, continuous soil fertility study in the Southern U.S. This study’s yields reflect growing conditions during the season. The Cullars Rotation Experiment is an excellent site to see dramatic nutrient deficiencies compared to healthy crops each year. Treatments include with and without winter legumes, timing of fertilizer application, 2-year rotations with corn with and without winter legumes, and a 3-year rotation with corn, wheat and soybeans. This experiment has become highly visible because of its location adjacent to the Jules Collins Smith Museum of Art in Auburn.
