- Abstract:
- ... Atrazine was amended into an agricultural drainage ditch and constructed wetlands for the purpose of monitoring transport and fate of the pesticide. Aqueous half lives of 6 and 16 to 48 days in drainage ditch and constructed wetlands, respectively, were found. Flow paths of 50 m and 103 to 281 m were required to mitigate atrazine in the drainage ditch and constructed wetlands, repectively. This in ...

- Abstract:
- ... The movement of fallout ¹³⁷Cs from soils in three north Mississippi watersheds was found to be logarithmically (r = 0.89) related to potential soil loss as calculated by the Universal Soil Loss Equation. Analysis of other published data on ¹³⁷Cs as well as the north Mississippi data also showed a significant (r = 0.95) logarithmic relation existing between soil loss and ¹³⁷Cs loss from soils. This ...

- Abstract:
- ... The amount of fluometuron [1,1-dimethyl-3-(α,α,α-trifluoro-m-tolyl)urea] in runoff water under different environmental conditions was determined in the southern U.S. and Puerto Rico. In Mississippi, Puerto Rico, and Texas, runoff water was collected from soil sprayed with 4.4 kg/ha of fluometuron each year for 3 years. Tests were conducted in Tennessee for 2 years and in North and South Carolina f ...

- Abstract:

In the Memphis catena, the well-drained Memphis (fine silty, mixed, active, thermic Typic Hapludalfs) is more erodible than the moderately well-drained Loring (fine silty, mixed, active, thermic Oxyaquic Fragiudalfs) and Grenada (fine silty, mixed, active, thermic Glossic Fragiudalfs). We hypothesized that soil wetness and Fe oxide status affects the erodibility of these soils. Samples (<2 mm) of ...

- Abstract:
- ... Grass hedges are narrow (1-2 m wide) parallel strips of stiff, erect, grass planted near to or on the contour of fields but crossing swale areas at angles convenient for farming. They serve as guides for contour cultivation, retard and disperse surface runoff, cause deposition of eroded sediment, and reduce ephemeral gully development. After three years of tilled fallow between mixed-species hedge ...

- 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 dissipation of the cotton defoliant tribufos was measured in laboratory incubations and on 0.2-ha research plots. Computed 50% dissipation time (DT50) using nonlinear and linear kinetic models ranged from 1 to 19 days. Data indicated that exchangeable soil aluminum inhibited tribufos-degrading soil organisms. Nevertheless, measured DT50 values were 40 to 700 times less than the aerobic soil h ...

- Abstract:
- ... No-till practices generally reduce runoff (RO) and soil loss (SL) by contributing to accumulations of soil organic matter (SOM) in the near-surface zone. This research was conducted to determine the effects of SOM contents on RO and SL from two highly erodible soils using crops that produce a wide range of residue, in the context of long-term tillage studies in widely separated climatic regions.

- Abstract:

This largely agricultural landscape undergoes a bulk soil erosion rate of ∼480 t·km⁻²·yr⁻¹ (∼1500 × 10⁶ t/yr, across the MS Basin), and a soil organic carbon (SOC) erosion rate of ∼7 t·km⁻²·yr⁻¹ (∼22 × 10⁶ t/yr). Erosion translocates upla ...

- Abstract:

The need to control glyphosate [N-(phosphonomethyl)glycine]-resistant weed biotypes with tillage and preemergence herbicides in glyphosate-resistant crops (GRCs) is causing a reduction in no-tillage hectarage thereby threatening the advances made in water quality over the past decade. Consequently, if environmental gains afforded by GRCs are to be maintained, then an in-field best management pract ...

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 ...
