organism: uncultured bacterium
description: U-IF(Unamended-intermittent flood): These plots had not been exposed to any As-containing products for at least the 20 years and received an intermittent flooding treatment.  The plots were flooded and allowed to dry until surface cracking was evident and were then re-flooded. This irrigation scheme continued for the entire 2008 growing season. Equal quantities of community DNA from each of three field-level replicates were composited into one sample per treatment and sequenced for 16S rRNA.
