- Abstract:
- ... Erosion prediction utilizing digital elevation models (DEMs) is a logical advancement for automating the simulation process for models such as the Water Erosion Prediction Project (WEPP). The effects of using different DEM resolutions on watershed simulations and the ability to accurately predict sediment yield and runoff from different rainfall event sizes were studied using three application met ...

- Abstract:
- ... Concentrated flow can cause gully formation on sloping lands and in riparian zones of floodplains adjacent to incising stream channels. Current practice for riparian gully control involves blocking the gully with an earthen embankment and installing a pipe outlet. Measures involving native vegetation would be more attractive for habitat recovery and economic reasons. To test the hypothesis that sw ...

- Abstract:
- ... The USDA Annualized Agricultural Non-Point Source Pollution model (AnnAGNPS) has been developed to aid in evaluation of watershed response to agricultural management practices. Previous studies have demonstrated the capability of the model to simulate runoff and sediment, but not phosphorus (P). The main purpose of this article is to evaluate the performance of AnnAGNPS on P simulation using compa ...

- Abstract:
- ... The carry-over effects from one year to the next of surface residue and tillage management decisions on runoff and erosion are not clear. The dynamics of runoff and erosion processes during rainfall events are likely dependent on the tillage and residue management system. The objective of this study was to elucidate the effects of tillage practices and residue management, by removal of residue cov ...

- Abstract:
- ... Studies have shown that no-till (NT) management reduces soil erosion relative to chisel/disk-tillage (CT) and that this benefit may increase over time. There are fewer data, however, to separate the erosion-reduction contributions of surface residue mulch from those of improved soil properties under NT. The objective of this study was to quantify these separate contributions for a silt loam soil ( ...

- 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:
- ... Soil samples were collected on a 0.4-ha (1.0-ac) grid from two agricultural fields in northeastern Mississippi. The samples were measured for soil nutrient composition, soil texture, and diffuse reflectance between 250 and 2500 nm. The data were examined for two purposes: (1) to understand the relationships between soil properties and reflectance spectra, and (2) to understand the sources of varia ...

- Abstract:

A field study was established in the fall of 1993 on Tunica clay soil to evaluate the response of cotton to profile modification tillage relative to more conventional types of tillage for clay soil. Ten treatments were replicated four times using plots 15 m wide x 30.5 m long in a wide-bed controlled-traffic production system. Annual tillage treatments included bedding, disking, chiseling, subsoil ...
