  1. Day-x: timing of sediment sampling in days relative to the start day (Day-0) of the experiment. Each sampling event represents the average OM percentage in each treatment. The OM was estimated by percentage (%) based on the differences in dry weight of samples before and after muffle burning. SD: standard deviation.
