      abstract = {Many agriculturalists have been focusing on the most  efficient farming method that would produce the maximum  yield while still sustaining the soil ecosystem. Soil  samples were collected from the “ Old Rotation ” area  (Auburn University, Auburn, AL ), and were assessed for  soil biochemical, chemical and biological characteristics  related to soil quality. Treatments of the experimental  site were a control with no legumes or N fertilizer; cotton  every year with winter legumes ; a 3 - yr cotton - corn -  soybean rotation with wheat and winter legumes ; and cotton  every year with N fertilizer . Impacts of irrigation were  also tested between the sites. Assays were performed  measuring phosphomonoesterase and phosphodiesterase  activity, soil organic carbon , soil pH , and microbial  diversity. The 3 - year and winter legume rotation s showed  significant differences in the structure and membership of  microbial communities and differences in biochemical  activity. These results further demonstrate the ability of  crop rotation to enhance the soil health of agricultural  ecosystems.},
