This rotation also includes rotations with corn, soybean, and small grains. It was placed on the National Register of Historical Places in 1988 and is celebrating its centennial on 4 October 1996. Information from this test provided evidence that rotation with legumes could sustain and actually improve yields of cotton and corn in Alabama soils. Data from this experiment have been the source of numerous scientific, popular, and educational publications on cotton production and soil fertility. Because only minor changes have been made in the cropping systems, it continues to document the effect of these systems on productivity, soil and environmental quality, and sustainable agriculture.
Recent data show the effect of increasing soil organic matter on cotton productivity.
