Fig. 3. (a) 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]. (b) Relationship between runoff to rainfall ratio and dissolved inorganic P concentrations in runoff, expressed as a ratio of the maximum concentration, as measured by Kleinman et al. (2002a).
