Management dependent soil properties of cultivated versus non-cultivated southeastern Coastal Plain ecosystems 

Levi, Matthew (2007-12-15)
Management dependent properties describe dynamic soil quality. Comparisons of disturbed to reference sites are not extensive in the southeastern (SE) U.S. due to scarcity of undisturbed land. Objectives of this study ...

Management Effects on Yield and Flavonoid Content in American Skullcap (Scutellaria lateriflora) 

Shiwakoti, Santosh (2012-01-09)
American Skullcap (Scutellaria lateriflora) is a member of the mint family (Labiatae or Lamiaceae), and is a medicinal herb traditionally used for its mild relaxant properties attributed to its content of flavonoids. Field ...

Management of Palmer Amaranth in Glufosinate-Resistant Cotton and Cogongrass Eradication in the Southern United States 

Aulakh, Jatinder (2013-04-22)
The Southeastern US is struggling with cogongrass (Imperata cylindrica) and glyphosate- resistant Palmer amaranth (Amaranthus palmeri)–two of the most difficult-to-manage weeds of non-crop and row-crop areas, respectively. ...

Management of Ultra Narrow Row Cotton 

Delaney, Dennis (2006-08-15)
Ultra Narrow Row cotton (Gossypium hirsutum L.) production systems may have the potential to increase lint yields, decrease risks to losses from water stress, and allow the use of conservation systems which could contribute ...

Management-Dependent Soil Variability and Surface Hydraulic Properties of Southeastern U.S. Coastal Plain Plinthic Kandiudults 

Cochran, Joe Frank (2010-11-15)
Soil surveys are the foundation for natural resource planning and management and have been developed to illustrate and characterize the spatial variability of our soil resource; however, decade-scale temporal variability ...

Measuring Phenotypic and Genetic Variances and Narrow Sense Heritability in Three Populations of Annual Ryegrass (Lolium multiflorum Lam.) 

Chugh, Kamal (2013-07-19)
Annual ryegrass, also known as Italian ryegrass is a cool season bunch grass supposed native to Italy and belongs to family Poaceae. Annual ryegrass is a short duration grass chiefly used for pasture and silage in dairy ...

Microbial Implication of Iron Oxide Nanoparticles 

Starr, Kimberly (2010-05-12)
Magnetite nanoparticles (Fe3O4) designed for remediation will be intentionally released into the environment; however, little is known regarding their impact on bacterial populations. Research was conducted to 1) investigate ...

Middle-Season Drought Tolerance in a RIL Population of Cultivated Peanut 

Carter, Joshua (2015-05-07)
Grown extensively in Asia, Africa, and the Americas, cultivated groundnut or peanut (Arachis hypogaea L.) is one of the world’s most important food and oilseed crops. However, a vast majority of peanut crops are grown ...

Mineralization in Soils Amended With Manure as Affected by Environmental Conditions 

Watts, Dexter (2007-05-15)
Concerns for environmental quality have prompted interest in recent years to develop agricultural practices that mitigate nutrient loss to the environment. It is imperative that management practices are developed that ...

A Molecular Approach to Determine the Origin of Fecal Bacteria in the Catoma Creek Watershed 

Wijesinghe, Rasanthi (2005-12-15)
High concentrations of fecal indicator bacteria are the most common cause of surface-water impairment in Alabama. A 37 km segment of Catoma Creek in Montgomery Country has been included on Alabama 303(d) List of impaired ...

Mowing and nitrogen source effects on ammonia volatilization from fertilizers applied to turfgrass 

Knight, Ellen (2007-05-15)
Although ammonia (NH3) volatilization can be a pathway of nitrogen (N) loss from turfgrass systems, the magnitude of this loss has not been well quantified, especially from N sources other than urea. The objective of this ...

Mowing Height, Nitrogen Rate and Source Effects on Establishment and Maintenance of Tifway and TifSport Bermudagrass 

Hicks, Christy (2006-12-15)
Hybrid cultivars of bermudagrass (Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy) are the predominant turfgrasses used on golf courses and athletic fields throughout the southeastern United States, and in warm, ...

A New Spin on an Old Crop for Bioenergy: Sorghum 

Rocateli, Alexandre Caldeira (2010-08-02)
According to Renewable Fuels Standard (RFS) – Energy Policy Act of 2005, the U.S. must reduce foreign oil dependence, where the target is to produce 36 billion gallons of oil equivalent in 2022 (RFA, 2010). Cellulosic ...

Nitrogen release characteristics of commercial organic fertilizers in turfgrass 

Green, Brandon (2011-07-18)
Although organic fertilizer sources are widely marketed for application to turfgrasses, there is limited research that examines their nitrogen (N) release characteristics. For this research project, ‘organic’ refers to ...

Overseeded TifEagle Bermudagrass Putting Greens: Effects of Nitrogen (N) Rate and Traffic 

Bruner, Phillip (2013-07-30)
Hybrid bermudagrass (Cynodon dactylon x C. transvaalensis Burtt-Davy) putting greens are often overseeded with a cool season species at the onset of fall dormancy. Intended to provide winter color for the putting surface ...

Phosphite in Soil and Turfgrass
