Data were collected from tile drains of total dissolved phosphorus (TDP), total phosphorus (TP) concentrations measured in mg P/L. Each measured concentration was obtained from the selected study sites reviewed in literature. Quartiles were obtained to describe the data trend for TDP and TP. The TDP concentrations ranged from 0.002-0.310 mg/L with n=88 concentrations obtained. Additionally, TP concentrations ranged from 0.008-1.13 mg/L. Probability of exceedance and quartiles were determined for the set of phosphorus concentrations with values resulting in TDP concentrations above below 0.03 mg/L P. In order to explain the significance of the tile drained TDP and TP, further data including, total phosphorus in surface runoff, must be compiled and compared. The comparison will be presented in a later paper. This comparative analysis of total dissolved and total phosphorus concentrations may provide insight on quantifying the stress surface runoff and tile drainage phosphorus apply to surface waters.(Download PDF) (Export to EndNotes)
