Phosphorus Reduction in Runoff Using a Steel Slag Trench Filter System
(Oklahoma State University, 2012-12-01)
Excessive concentrations of phosphorus (P) can lead to the deterioration of surface waters by eutrophication. The objective of this study was to evaluate the performance of a steel slag trench filter system developed for ...
Investigation of insecticide leaching from potted nursery stock and aquatic health benefits of bioretention cells receiving nursery runoff
(2013-12)
Tree nurseries and greenhouses within the USDA red imported fire ant (RIFA) quarantine zone are required to incorporate insecticides into their potting media to prevent artificial spread of RIFA. Bifenthrin and fipronil ...
Determining bacterial and nutrient concentrations and loadings of surface runoff from differing grazer access and vegetative cover in north-central Oklahoma
(2022-05)
Water bodies in Oklahoma are primarily fed by runoff, making bacterial and nutrient contamination of surface runoff a significant water quality concern. The purpose of this thesis was to determine the impacts of grazing ...
Investigating scale, rainfall-runoff sequences and BMP effects on phosphorus, runoff and sediment yield
(2004-12)
Scope and Methods of Study: 1) Scale effects on phosphorus (P) loss and runoff depth from pastures were investigated by summarizing water quality data from 19 research projects. Spatial (area) and temporal (days after ...
Observing the Impacts on the Spatial Allocation of Crop Acres in the Fort Cobb Watershed caused by Maximizing Profit Subject to Runoff Constraints
(Oklahoma State University, 2004-12-01)
Budgets for peanuts, conventional till and no-till wheat, sorghum, and CRP production were generated. Using the SWAT model annual crop, sediment, nitrogen, and phosphorus yields were predicted for each hydrologic response ...
