Fig. 1. Daily rainfall and flow, and logarithm of number of Escherichia coli and total coliforms and of NH₄⁺–N and dissolved reactive phosphorus (DRP) concentrations in tile drainage water near the time of inject (INJ) or topdress (TD) application of different rates of sidedressed liquid swine manure (LSM) in (A) 2000, (B) 2001, and (C) 2002 (all but total coliforms). LSM subscript indicates rate in m³ ha^–1. Time scales are logarithmic and labeled so that 0 = time of LSM application for each plot (negative values on the time scale thus refer to sampling events before application). Breaks in the x axis separate sections of data with different time scales or indicate instances when no samples were collected.
