Functional group profiles in soil samples collected from distinct locations (Nashville, Oakdale, and Towers) and samplings (pre-soybean, mid-soybean, and post-soybean)_ Numbers represent the ratio of the total relative area of a chemical in wheat plots compared to fallow ((WT/FL)*100)_ Gray/white cells highlight higher concentrations of a chemical group in wheat or fallow plots under their respective fields and samplings_
