Fig. 4. Relationship between dissolved inorganic phosphorus (DIP) concentrations in runoff from soil boxes where manures had been surface-applied and subjected to simulated rainfall as measured in this study and by Kleinman et al. (2003, 2002a) and Kleinman and Sharpley (2003) and as predicted by Eq. [2], [3], and [4] with (a) an adjustment for the ratio of runoff to rainfall, and (b) a second adjustment based on the initial infiltration of manure dissolved P in the freely draining liquid of swine and dairy manures.
