Denitrification in a best management practice bioretention system
This study investigates the occurrence of denitrifying soil bacteria in a bioretention system located in Singapore and containing a saturated anoxic zone intended to facilitate denitrification. Soil samples were collected from six depths within the rain garden, four of which were within the …

Performance Analysis of an Urban Stormwater Best Management Practice Retrofit
… the primary objective of traditional stormwater best management practices (BMPs) was to attenuate peak runoff discharges from urban areas. There has been growing demand to construct BMPs that improve stormwater runoff quality to reduce pollutant loading into downstream water bodies. A BMP located …

Evaluating the Two-Stage Ditch as a New Best Management Practice
… ditch in a hydrologic model as a conservation practice, comparing the model outputs with observed water quality from the two-stage ditch that was part of this study, and 4) simulate the dominant mechanisms controlling nutrient retention in the two-stage ditch at the watershed scale using the …

Best Management Practice Use and Efficacy for the Virginia Nursery and Greenhouse Industry
Best management practices (BMPs) are used in the nursery and greenhouse industry to increase production efficiency, and also serve to help meet clean water limitations on contaminants entering waters such as the Chesapeake Bay Watershed. Research is lacking on which BMPs are most widely used or …

Application of the Analytic Hierarchy Process Optimization Algorithm in Best Management Practice Selection
The efficiency of a best management practice (BMP) is defined simply as a measure of how well the practice or series of practices removes targeted pollutants. While this concept is relatively simple, mathematical attempts to quantify BMP efficiency are numerous and complex. Intuitively, the …

Evaluation of Sedimentation Control as a Best Management Practice for Removing Copper-based Crop Protectants in Plasticulture Runoff
… ± 99 mg/L dissolved copper). Sedimentation, a best management practice for reducing copper loadings, was found to reduce the total copper concentrations in runoff by 90% to a concentration of 245 ± 127 mg/L; however, dissolved copper concentrations remained stable, averaging 139 ± 55 mg/L. …

Assessing the use of exfiltration pervious pavements as a best management practice for storm water management for Lusaka urban
Stormwater management is being justified as a fundamental line of consideration in achieving sustainable urban development. Lusaka urban experiences impacts ensuing from developments in form of urban floods. This study was undertaken in Lusaka urban to assess the use of a full exfiltration pervious …

Modeling farmer decision-making using an agent-based model for studying best management practice adoption rates: A typological approach
… to this problem. The implementation of best management practices (BMPs) by farmers could greatly reduce the amount of nutrient runoff into the surrounding watershed. For this to be effective, however, farmers must implement these practices. Understanding the factors that farmers consider …

Pollutant Monitoring of Effluent Credit Trading Programs For Agricultural Nonpoint Source Control
… by financing agricultural nonpoint source best management practices. It describes the results of a national survey of existing trading programs that assessed how each program determines nonpoint source baseline pollutant discharges, pollutant reductions attributable to best management …

Integrating cover crops into crop rotations in upstate Missouri
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best management practices for conservation, soil health could …

Impacts of Best Management Practices on Farm Financial Performance
… through strategy development and execution. A best management practice is broadly defined as a practice that is considered to be most effective in improving business performance. This study examined the relationship of financial leverage and management practices with financial performance on a …

Understanding Potential Agricultural Owner-Operator And Tenant Adoption Of Saturated Buffers In Elm Creek Watershed, Minnesota
Saturated buffers are a new agricultural best management practice that aims to redirect nitrogen laden subsurface tile water into a buffer area to promote denitrification, thus reducing excess nutrients in nearby water bodies This study explores factors that influence adoption of this emerging …

Simulating the Cost and Legacy N Reduction Potential of Denitrifying Spring Bioreactors Installation in the Chesapeake Bay Watershed
… springs. Denitrifying spring bioreactors are a best management practice that offers an opportunity to abate N from groundwater springs. The objective of this research is to estimate the regional abatement costs to remove legacy N using bioreactors. We identified 196 candidate springs for …

Modeling Best Management Practices on Flow and Sediment using the Rangeland Hydrology and Erosion Model
… Dakota’s rangelands. Rangeland conservation and management requires the ability to assess the potential impacts of best management practices on sediment yield and runoff in order to help mitigate negative effects of erosion and sedimentation on soil vegetation productivity and water quality. This …
