description: M-CF (MSMA-continuous flood): These plots were amended with monosodium methylarsenate (MSMA) and had soil-As concentrations of ~25 mg kg-1. The plots were continuously flooded and had a water depth of ~10-cm until one week before harvest in 2008. Equal quantities of community DNA from each of three field-level replicates were composited into one sample per treatment and sequenced for 16S rRNA.
