The first Workshop on Agricultural Air Quality: State of the Science was held at the Bolger Center in Potomac, Maryland from 4 to 8 June 2006. This international conference assembled approximately 350 people representing 25 nations from 5 continents, with disciplines ranging from atmospheric chemistry to soil science. The workshop was designed as an open forum in which participants could openly...

Uncertainty of best management practice (BMP) effectiveness is an important factor in the development watershed plans. This study explored uncertainty BMP reducing total nitrogen (TN) load owing to hydrological parameters, thereby improving their reliability. A model, annualized agricultural non-point source pollution (AnnAGNPS), was employed evaluate four potentially feasible BMPs (i.e., ripar...

This study evaluated the best management practices on how to manage soil losses from catchment and reduce sediment load into a dam reservoir. aimed evaluate relationship of runoff, loss, yield with practice (BMP) scenarios in GeoWEPP environment for selected three micro-watersheds (hot spot areas) Megech watershed, upper Blue Nile Basin. The impacts four agricultural BMP scenarios, including fo...

The reduction of agricultural nonpoint source (NPS) pollution is essential to protect the quality of North Carolina's water resources. In order to reduce these pollutants, increased implementation of Best Management Practices (BMPs) by individual producers is being proposed. Recommended BMPs include soil and water conservation practices, fertilizer and animal waste management and integrated pes...

Best Management Practices (BMPs) incentive programs have been introduced to protect agricultural land and reduce nutrient runoff in watersheds. However, their voluntary nature has not led the expected high participation rates. We examine influencing factors underlying drivers that are associated with BMP adoption farmer preferences for specific BMPs. Data collected through an online survey Onta...

Agriculture is both the cornerstone of global food security and one main drivers environmental degradation. To address existing potential impacts agriculture, policymakers are increasingly focussing on influencing farmers’ behaviour to adopt best management practices (BMPs). One strategies adopted provision advice aimed at raising awareness pollution mitigation measures. By improving awareness,...

Assessing best management practice (BMP) effectiveness in large basins is complicated by hydrologic variability, ecosystem complexity, and issues of scaling. A traditional approach to assessing BMP effectiveness in large watersheds is to forecast several BMP scenarios and compare their performance relative to a baseline scenario. While this approach may provide insight into the effectiveness of...

Best management practices (BMPs) started in Florida citrus (Citrus spp.) in the 1990s and have evolved to play a major role in production practices today. One of the earliest BMPs in Florida arose from concerns over nitrate-nitrogen concentrations in some surfi cial groundwater aquifers exceeding the 10 mg·L–1 drinking water standard. This occurred in an area of well-drained sandy soils known a...
