- Abstract:
- ... The effectiveness of conservation initiatives on private lands in the southern United States plays an important role in improving provision of ecosystem services and mitigating negative environmental impacts. However, participation in conservation efforts is in part affected by landowner concern about environmental issues. This study used a seemingly unrelated regression (SUR) to quantify the impa ...

- Abstract:
- ... Agricultural fertilizer use is widely acknowledged to be a leading cause of water pollution. Yet, no national estimates exist on the effect of fertilizer application on concentrations of agricultural pollutants in US watersheds. This paper employs a watershed‐level panel data on nitrogen and phosphorus pollution readings to examine the impact of fertilizer use on US water quality over a fifty‐five ...

- Abstract:
- ... A central challenge in the Mississippi River Basin is how to continue to support profitable agricultural production, provide water supply, flood control, transportation, and other benefits, while reducing the current burden of environmental degradation. Several practices have been shown to reduce nutrient runoff and water pollution, and improve soil fertility, while often yielding profits for farm ...

- ... A community-based participatory research was utilized to address the coastal community's concern regarding Deepwater Horizon oil contamination of seafood. Therefore, we analyzed polycyclic aromatic hydrocarbons (PAHs), major toxic constituents of crude oil, in the seafood collected from gulf coast (Louisiana, Alabama and Mississippi) during December 2011–February 2014. PAHs were extracted from edi ...

Here, we demonstrate the ongoing biodegradation of weathered Macondo Well (MW) oil residues by tracing oil-derived carbon into active microbial biomass using natural abundance radiocarbon (14C). Oiled-sand patties and non-oiled sand were col ...

- Abstract:
- ... It often difficult to determine the environmental soundness of rivers and streams particularly those that may have been impaired by farming as might be the case in the Mississippi Delta. Analysis of fish data can be simplified by calculating mathematical indices that provide a simple number that indicates an impaired or healthy stream. This research shows that while the index may provide a sound w ...

- Abstract:
- ... Phosphorus (P) loss from agricultural fields is of environmental concern because of its potential impact on water quality in streams and lakes. The Mississippi Delta has long been known for its fish productivity and recreational value, but high levels of P in fresh water can lead to algal blooms that have many detrimental effects on natural ecosystems. Algal blooms interfere with recreational and ...

- ... Reduction of nonpoint source pollutants, principally sediment and nutrients moving from cultivated fields to surface waters, is a major challenge. Remnants of once-extensive natural wetlands occur across the agricultural landscape, and it has been suggested that these areas might be managed to yield improved wetland function in terms of trapping and retention of nonpoint source pollutants.

- ... BACKGROUND: Contamination of surface waters by pesticides is a concern in the United States and around the world. Innovative mitigation strategies are needed to remediate this potential environmental contaminant. One potential solution is to divert pesticide-laden drainage or surface water through agricultural rice fields. With a hydroperiod, hydrosoil and hydrophyte (rice), these systems serve es ...
