Interpretive Summary: Information on soybean and cotton rotations, particularly their effect on soil fertility is limited. Scientists at the USDA_ARS Crop Production Systems Research Unit at Stoneville, MS examined six irrigated cotton:soybean rotation systems for changes in soil fertility levels from 2012 to 2016 and found no differences in cation exchange capacity, organic matter, pH, or macro nutrient levels among the rotations, over the five sampling periods nor weed control methods used for either crop.

Technical Abstract: The effects of cotton (Gossypium hirsutum L.):soybean [Glycine max (L.) Merr.] rotations on the soil fertility levels are limited. An irrigated soybean:cotton rotation experiment was conducted from 2012 through 2015 near Elizabeth, MS. Rotation sequences were; continuous soybean, continuous cotton, cotton followed by soybean, soybean followed by cotton, soybean followed by two yr of cotton, and cotton followed by two yr of soybean. A weed control treatment of a non-glyphosate post-emergence vs. glyphosate post-emergence was used in both crops. Soil samples taken prior to planting each year and in 2016 showed no differences in cation exchange capacity, organic matter, pH, or macro nutrient levels among the rotations, over the five sampling periods nor weed control methods used for either crop.
