Evaluating Agricultural Best Management Practices to Mitigate Neonicotinoid Transport in Water and Soil
… health when they are transported from agricultural fields. To minimize environmental impact of neonicotinoid pesticides to non-target organisms, it is important to quantify the movement of neonicotinoids from agricultural fields and examine how conventional agricultural practices can be …

An Assessment of the Quality of Agricultural Best Management Practices in the James River Basin of Virginia
… cost, rapid method of quantifying the quality of agricultural best management practices (BMPs). Best management practices are either cost-shared, where some or all of the capital costs of the practice were subsidized with federal, state, or local funds, or non cost-shared, where the cost of the …

Post-implementation re-assessment of agricultural best management practices on watersheds of Conesus Lake: Effects on stream water chemistry and aquatic macroinvertebrate communities
… to the Environmental Protection Agency (EPA). Agricultural best management practices (BMPs) are intended to improve water quality, reduce sediment and nutrient runoff, and remediate the effects of altered hydrology. BMPs were installed in the early 2000s in the Conesus Lake watershed and have …

Uncertainty Analysis of the Performance of a System of Best Management Practices for Achieving Phosphorus Load Reduction to Surface Waters
… algal blooms suggests an inadequate phosphorus management system that results in excessive loads to the lake. In response, Canadian and United States’ governments have issued a new management objective, a 40% reduction in total and dissolved reactive phosphorus loads relative to 2008. To provide …

Quantifying the Potential for Non-Point Source Pollution in Model Urban Landscapes
… Virginia and beyond. While research on agricultural best management practices in nutrient management and nutrient and soil stabilization has made progress in reducing agricultural contributions to nutrient and sediment loading of watersheds, little is known about how land covers of …

Legacy Nutrient Management and Remediation in Diverse Agricultural Watersheds
Excess nutrient loading from agricultural landscapes remains a primary driver of freshwater eutrophication in the United States, despite decades of conservation investment. In many watersheds, water quality impairments persist due to the accumulation of legacy nutrients—phosphorus (P) stored in …
