Agroecosystem Effects on Carbon Sequestration and Soil Function in Tennessee Valley (Alabama) Paleudults

Croy, Andrew (2011-12-15)

Agronomic management affects soil organic matter (SOM) pools that impact chemical and physical properties, soil carbon (C) sequestration, soil quality, and ultimately, soil function. Pools of SOM and management-dependent ...

Agroecosystem Management Effects on Carbon And Nitrogen Cycling across a Coastal Plain Catena

Gacengo, Catherine (2008-08-15)

Agricultural activities contribute an annual increase in radiative forcing of about 20%. In southeastern US, use of cover crops in conservation tillage (CsT) has increased in recent years. However, data on soil C and N ...

Analyzing the Use of Publicly Available Multispectral Imagery to Guide the Creation of Soil Sampling Schemes

Oldag, Jordan (2020-02-26)

As site-specific nutrient management has grown in popularity, the need for accurate soil fertility data has increased. Unfortunately, the cost of detailed soil sampling has prohibited many farmers and consultants from ...

Assessing Zeolite Amended Bioretention Media for Removal of Nutrients and Metals from Stormwater

Sweeney, Lillie (2020-08-06)

Bioretention cells are installed to treat stormwater through physical, biological, and chemical processes facilitated by a permeable soil media. The soil media is commonly composed of sand, silt, clay, and organic matter, ...

Characterization of Pecan Shells for Value-added Applications

Littlefield, Brad (2010-07-30)

There is a growing need in the United States to decrease dependence on fossil fuels because of energy security and environmental concerns associated with their use. Energy derived from biomass is especially important to ...

Cover Crop Effects on Soil Hydrology

Bonilla, Rodolfo (2022-05-09)

Cover crops are known for their positive and significant effects on soils. They contribute to growing subsequent crops, reducing soil erosion, increasing water infiltration, and improving nutrient management. Cover crops ...

Design Guidance and Development of Construction Stormwater Technologies

Liu, Lan (2020-10-19)

As one of the largest sources of nonpoint source pollution, soil erosion has become an increasingly important topic in the U.S. Construction sites. Erosion and sediment control (ESC) practices are commonly used on ...

Development of Reliable Erosion Indices for Climate-Informed Soil Conservation in the Southeastern United States

McGehee, Ryan (2016-12-09)

A new methodology and corresponding dataset are recommended for a more accurate calculation of erosion index (EI) and erosivity (R) that was more consistent with observations from superior data sources. NOAA NCDC DSI-3260 ...

Evaluation of Indicator of Reduction in Soil (IRIS) Tubes to Verify Wetland Hydrology in Constructed Wetlands

Liggett, Cole (2018-11-15)

Wetlands are essential components of the environment that provide unique functions and values to the ecosystems in which they occur. As urban population and the economy continue to grow, impacts to wetlands are unavoidable ...

Evaluation of Water-use in Turfgrass

Githinji, Leonard (2007-12-15)

This dissertation examined the response of four hybrid bluegrasses [Texas bluegrass (Poa arachnifera Torr.) × Kentucky bluegrass (Poa pratensis L.)], HB 129 (‘Thermal Blue’), HB 130, HB 328 and HB 329 (‘Dura Blue’) and two ...

Exploring the use of ground penetrating radar for determining floodplain function of restored streams in the Gulf Coastal Plain, Alabama

Eckes, Samantha (2018-05-01)

Accurately characterizing subsurface structure and function of remediated floodplains is indispensable in understanding the success of stream restoration projects. Although many of these projects are designed to address ...

Growing Degree-Days Optimize Trinexapac-ethyl Reapplications for Ultradwarf Bermudagrass Putting Greens

Brown, Austin (2019-07-09)

Applying trinexapac-ethyl (TE) is a standard practice for growth suppression and quality improvement of ultradwarf bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy] putting greens, but research is ...

Hydrology, Water Quality, and Channel Morphology Across an Urban-rural Land Use Gradient in the Georgia Piedmont, USA

Schoonover, Jon (2005-12-15)

The southeastern United States is experiencing rapid urban development. Consequently, Georgia’s streams have been threatened by hydrologic alteration, nutrient and bacteriological impairment, and channel morphometry changes ...

Hydromorphology and Plinthite Characterization of Some Alabama Coastal Plain Soils

Smith, Richard (2007-12-15)

Estimating seasonal high water tables (SHWTs) within soils by the evaluation of redoximorphic features is critical for soil interpretations. Certain redoximorphic features indicate contemporary moisture regimes, while ...

Improvements in Construction Stormwater Treatment using Flocculants

Kazaz, Billur (2022-05-03)

Construction stormwater runoff constitutes an increased risk for downstream water bodies if unmanaged sediment-laden discharge exits a construction site. Federal and state regulations emphasize the significance of erosion ...

Investigations of Water Supply and Water Quality Issues Related to Inland Shrimp Farming in Western Alabama

Boyd, Christopher (2006-08-15)

Examination of data on chloride concentrations in well waters revealed that an area in Greene, Sumter, Hale, Marengo, and Wilcox Counties had the greatest potential for inland culture of marine shrimp. A few places in ...

Management and Landscape Influences on Soil Organic Carbon in the Southern Piedmont and Coastal Plain

Causarano, Hector (2006-08-15)

Southern Piedmont and Coastal Plain soils have undergone severe degradation, which is reflected in low soil organic carbon (SOC) contents. Restoration of SOC would improve soil quality and C sequestration, leading to a ...

Management and Landscape Variability Effects on Selected Coastal Plain Soil Physical Properties
