| Summary: | (Groundwater Loading Effects of Agricultural Management 1.0 %. Model simulation results included surface runoff and 1983; Mostaghimi et al., 1988). The purpose of this study a non-reactive tracer. The field was planted in corn and agreement between the measured results and the simulated and its oxidation to nitrate (Padgett and Leonard, 1993; and pesticides are the major contributors to the non-point and sediment losses (Leonard et al., 1987). The study approximately 10 miles west of the main campus in College Ashraf and Borah, 1992). The amount of atrazine lost from the atrazine, bromide, nitrate, ammonium, and sediment losses. central Texas. The site provided the unique opportunity to characteristics ranged from 0.35 to 0.83, indicating poor during the four month growing season surface water runoff emergent, were atrazine, bromide, and a granular fertilizer field due to sediment transport was estimated as 1.0 % of the initial amount applied using a fraction of organic carbon of located on the Brazos River floodplain was instrumented for measure the quantity and quality of runoff from an actual measured little atrazine in the runoff (0. 15 % of applied). Non point source (NPS) pollution is a growing concern in the percentage of ammonium can be attributed to volatilization respectively, with ammonium losses of 0.13 %. The lower results. river floodplain. A 0.89-ha agricultural research plot samples were analyzed for these four chemicals and total sediment on a research plot located in a river floodplain in solids. The site is located on the Texas A&M research farm source pollution problem in the United States (U.S. EPA, Station, Texas. The soil surface layer is a Ships Clay, surface water runoff studies. The chemicals applied, pre- Systems) model was used to simulate runoff events, chemical The bromide and nitrate losses were 4.0 % and 4.6 I/o, The correlation coefficients for simulated versus measured United States and the world. Sediment, nitrogen, phosphorous was to monitor the fate of certain agricultural chemicals and which contained ammonium and nitrate. Bromide was applied as which has high shrink/swell properties.
