Recommendations for Manure Injection and Incorporation Technologies for Phase 6 Chesapeake Bay Watershed Model

Proceedings Home W2W Home w2w17 logo


A Best Management Practice (BMP) Expert Panel was convened under guidance of the Chesapeake Bay Program’s (CBP) Water Quality Goal Implementation Team to assess and quantify Nitrogen and Phosphorus load reductions for use in the Phase 6 Chesapeake Bay Watershed Model when manure is injected or incorporated into agricultural lands within the watershed.…

Developing Science-Based Estimates of Best Management Practice Effectiveness for the Phase 6 Chesapeake Bay Watershed Model

Proceedings Home W2W Home w2w17 logo


The Chesapeake Bay Program (CBP) is a regional partnership that leads and directs Chesapeake Bay restoration and protection. The CBP uses a suite of modeling and planning tools to estimate nutrient (nitrogen and phosphorus) and sediment loads contributed to the Bay from its watershed, and guide restoration efforts.…

Environmental Management on Equine Farms or the Good, the Bad, and the Ugly

Why Look at Environmental Practices of Horse Farms?

Equine farms are often small acreages that may not have ready access to technologies and information appropriate to their farms. Westendorf et al. (2010a) found that many equine farmers use extension services less than other sources of information, but they may use feed stores or neighbors for information (Table 1); Marriott et al.…

Case Study of Contaminated Compost: Collaborations Between Vermont Extension and the Agency of Agriculture to Mitigate Damage Due to Persistent Herbicide Residues

Why Study Herbicide Contamination of Compost?

Picloram, clopyralid, aminopyralid and aminocyclopyrochlor are broadleaf herbicides commonly used in pastures due to effectiveness in controlling undesirable plants and the very low toxicity for animals and fish. In fact, some of these herbicides do not require animal removal post application.…

An NE-1441 Project: Proposed Methodologies for Administering a Multi-State Environmental Best Management Practices Survey of Equine Properties


Several states have reported that equine are the fastest growing segment of the livestock industry. Nationwide, equine has increased by 77% since 1997; and it is reported there are approximately 9.5 million horses in the United States (AHC, 2005). Proper management of equine operations requires the adoption of Best Management Practices (BMPs) to balance nutrient production and prevent erosion.…
