Impact/Purpose:
Water bodies and coastal areas around the world are threatened by excessive amounts of nitrogen (N) and phosphorous (P) from upstream watersheds, which can cause rapid proliferation of algae. These algal blooms negatively impact drinking water sources, aquatic species, and recreational services of water bodies by producing toxins, also called harmful algal blooms (HABs). Finding ways reducing nutrient losses from agricultural fields is paramount important for EPA program offices and regional partners to make informed decisions to better control nutrient losses from agricultural fields.
Description:
This presentation introduces the first edition of a special collection of literature reviews documenting performance and cost effectiveness of selected agricultural conservation practices (ACPs). The specific objectives are to summarize key information from each review paper and develop a comparative understanding of performance effectiveness and cost effectiveness of six ACPs. Based results from those six review papers, future needs were identified and discussed. Firstly, Studies of ACPs for performance effectiveness on dissolved P are limited; thus, more research is needed to find effective ACPs in reducing dissolved P. Furthermore, more studies are needed to better understand the cost-effectiveness including ecological benefits gained from implementing those ACPs in the future.
