- Abstract:
- ... The National Agricultural statistics Service (NASS) currently uses two distinct adjustment methods to account for nonresponse on the list side of its Agricultural Surveys. A complex imputation program is employed for crop (acreage, production, and stock) items, while an adjusted form of reweighting is used for livestock items. This paper examines the subtle differences in the two approaches. A uni ...

- Abstract:
- ... The formation of ephemeral gullies can significantly increase soil loss from agricultural lands and severely impact farm productivity. Erosion prediction technology and conservation management techniques would be greatly improved if the contribution from ephemeral gullies could be more accurately quantified. Field research in Mississippi, U.S.A. and Spain has revealed three categories of ephemeral ...

- Abstract:
- ... Sediment and its associated pollutants entering a water body can be very destructive to the health of that system. Best Management Practices (BMPs) can be used to reduce these pollutants, but understanding the most effective practices is very difficult. Watershed models are the most cost-effective tools to aid in the decision-making process of selecting the BMP that is most effective in reducing t ...

- Abstract:
- ... Historical streamflow and concentration data were used in regression models to estimate the annual flux of nitrogen (N) to the Gulf of Mexico and to determine where the nitrogen originates within the Mississippi Basin. Results show that for 1980–1996 the mean annual total N flux to the Gulf of Mexico was 1568000 t yr⁻¹ The flux was about 61% nitrate N, 37% organic N, and 2% ammonium N. The flux of ...

The ability of these ecosystems to mitigate potential contaminants is not well understood. Five sites along a 650-m agricultural ditch located in the Mississippi Delta Management Systems Evaluation Area (MDMSEA) were used to measure fate and effects of an esfenvalerate (insecticide) e ...

- Abstract:
- ... Grassland bird populations are sharply declining in North America. Changes in agricultural practices during the past 50 years have been suggested as one of the major causes of this decline. Field-border conservation practices encouraged by the U.S. Department of Agriculture's National Conservation Buffer Initiative meet many of the needs of sustainable agriculture and offer excellent opportunities ...

Currently, installation of erosion control structures (drop pipes) at the riparian zone--agricultural field interface halts gully erosion and simultaneously establishes one of four riparian habitat types. Avian communiti ...

The application of inorganic nitrogen fertilizers on agricultural landscapes has the potential to generate concerns of environmental degradation at fine to coarse scales across the catchment and landscape. Inorganic nitrogen species (NO₃ ⁻, NO₂ ⁻, and NH₃) are typically associated with subsurface flow processes; however, surface runoff from rainfall events in no-till agriculture with inorganic sur ...

This current study examined whether Leersia oryzoides, a common wetland plant, exhibits luxury uptake of nutrients from simulated farm runoff. The study also tested whether with subsequent decomposition, these nutrients are released back ...

Impact of agricultural activities on the quality of water resources can be minimized by implementing suitable agriculture land-use types. Currently, land uses are designed (location, type, and operational schedule) based on fie ...

Yet it is not known whether the common practice of repairing or obliterating these gullies during annual tillage activities exacerbates or mitigates soil losses over long time periods. Here, a numerical model is used to de ...

- Abstract:

Vegetation Buffer Strips (VBS), one of the commonly used off-field structural BMPs, when designed and placed correctly, can significantly improve the water quality. However, VBS takes up agricultural land used for crop pro ...
