Fig. 5. Concentrations of total dissolved phosphorus (TDP) in overland flow from intensively managed pasture (regrowth, GRN; recently grazed, GRS) on the first (diamonds) and second (squares) days of rainfall simulation. Samples were collected in 5-min increments from the first paired plot to produce overland flow; 30-min composite samples (ACOMP, BCOMP) and equilibrium flow samples (A30, B30) were collected from both plots.
