| Summary: | (Schizachrium scoparium (Michx.) Nash) and brownseed (TKN) imply that a strong correlation exists between [tg L-1 TP concentration typical of winter season runoff. acceptable, sustainable management technique with no threat affects seasonal patterns of runoff quantity and quality. and disturbance. Fire is necessary for natural maintenance and soil were established 3 km west of College Station, and water yield is well documented on an individual storm constituents in the first runoff event following the bum. determine the seasonal patterns of hydrological response and effective management tool which suppresses invading brush event basis, but little information is available on how this For example, total phosphorus (TP) concentration in first impact of rangeland prescribed bums on infiltration, erosion, limited to an increased concentration of many insoluble loss was generally greatest in winter and decreased through maintenance of pasture in the Post Oak Savannah is an monitored between December 1990 and November 1996 to of most grasslands and savannahs. Prescribed burning is an paspalum (Paspalum plicatulum Michx.). These catchments were post-bum runoff averaged about 500 jig L-1 compared with 100 quality during the four-year period with burning were not Relatively low standard deviations associated with mean responsive to precipitation patterns, site characteristics, Savannah region of Texas. Seasonal nutrient and sediment seasonal concentrations of TP and total Kjeldahl nitrogen seasonal runoff volume (M3 ) and nutrient loss (kg ha-'). significantly different from the patterns established during species and controls undesirable forb and grass species.

The water quality effects of burning were These data indicate that prescribed winter burning for Three adjacent 0.16 ha catchments with the same slope (4%) to maintaining water quality. Variation in nutrient and sediment loss via runoff is water quality associated with winter burning in the Post Oak |
