A sprinkling infiltrometer was used to evaluate total phosphorus (TP) and total soluble phosphorus (TSP) losses in surface runoff from plots receiving manure application rates of 22-135 MT/ha and from plots where manure had been incorporated to depths varying from 0-20 cm. Both laboratory and field trials were conducted utilizing simulated precipitation. Infiltrometer runs were repeated for various drying conditions of the soil manure mixture at time intervals varying from 1-30 days. Significantly higher TP and TSP loads in surface runoff were associated with surface applications of manure immediately followed by a precipitation event. For the standard 12-cm, 60-minute event, TP and TSP loads were as high as 13.4 and 7.7 kg/ha, respectively. These loads were 20-25 times greater than observed TP, TSP loads from control plots.
