Experiment Demonstrates 110 Years of Sustainable Agriculture

The oldest continuous cotton production experiment shows that winter legumes are as effective as nitrogen fertilizer in producing non-irrigated, 10-yr average cotton yields.

MADISON, WI, September 29, 2008A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods.

In 1896, Professor J.F. Duggar at the Agricultural and Mechanical College of Alabama (now Auburn University) started an experiment to test his theories that sustainable cotton production was possible on Alabama soils if growers would use crop rotation and include winter legumes (clovers and/or vetch) to protect the soil from winter erosion.
