Abstract/Contents:"This research was implemented to gain a better understanding of the relationship between runoff, hillslope hydraulics, and turfgrass growth. The research was conducted on a 6 to 8 % hillslope, on Arkport sandy loam soil (Coarse-loamy, mixed, active, mesic Lamellic Hapludalf). Runoff was collected from 51 natural rainfall events over a 30-month period. Site runoff losses varied from 0.10 mm to 19.0 mm. The most important factor in predicting runoff was hillslope location. Runoff from the lower slope was a factor of five greater than from the upper slope. This was due to the effects of greater clay content, lower soil infiltration rate and shallow through flow from up slope increasing the average soil moisture content on the lower slope by 20%. Measured infiltration rates varied with hillslope location and time. Over time the infiltration rates increased (lower and upper slope soils exhibited 70 and 66% increase respectively) and runoff losses decreased as a result of turfgrass growth. On average infiltration rates were twice as high in the upslope areas. Turf growth and formation of soil structure were the major factors in decreasing runoff and increasing infiltration over time. Both nutrient and pesticide mass losses were generally higher from lower slope areas. Nitrate (NO3--N) mass losses were 25% higher at the bottom of the slope. Phosphate (PO43--P) and ammonium (NH4+-N) mass losses were 4 and 5 times higher at the bottom of the slope respectively. The herbicides 2,4-D (2,4-dichlorophenoxyacetic acid), and dicamba (3,6-dichloro-2-methoxybenzoic acid) mass losses were 95, and 84% higher respectively from the lower slope. The concentration of nutrients and pesticides in runoff were not significantly different between upper and lower slope areas. This suggests that mass losses are driven by the difference in runoff volume as influenced by hillslope position rather than by concentration, of the compounds in runoff."
