Description: Infiltration and runoff were measured using a rainfall simulator and runoff frames at five sites. Three sites were located in hayfields and two were in pastures. One of the hayfield sites consisted of reclaimed mineland. Three management treatments (hayed, mowed, and fallow) were applied to the hayfield plots and two treatments (grazed and fallow) were applied to the pasture plots. Runoff volume was measured at 5-min intervals to an elapsed time of 30 min and then infiltration rates and accumulated infiltration were detennined. Runoff volumes were low from all treatments (runoff coefficients < 0.50), even under the high intensity used and high antecedent soil moisture conditions. Grazing did not affect infiltration in comparison to fallow. Initially, abstractive losses other than infiltration were also low « 9 mm). In general, hayed and mowed treatments had higher infiltration rates and accumulated infiltration than the fallow treatment. The reclaimed and unmined soils had similar infiltration variables. Linear relationships between initial abstraction and 5-min infiltration rate with degree of saturation were not significant at 5% significance level.
