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, ...

Assessment of Turmeric (Curcuma longa L.) Varieties for Yield and Curcumin Content 

Shi, Shanheng (2020-07-28)
Turmeric (Curcuma longa L.) is a rhizomatous herbaceous perennial plant belonging to the ginger family, Zingiberaceae. Currently, more than 80% of turmeric is produced by India and turmeric products are exported to numerous ...

BIOGEOCHEMICAL STORAGE AND TRANSFORMATION OF SEDIMENTS FROM GEOGRAPHICALLY ISOLATED WETLANDS IN AGRICULTURE LANDSCAPES 

Eggert, Chloe (2022-12-08)
Geographically Isolated Wetlands (GIWs) provide many beneficial ecosystem services including biogeochemical storage and processing. However, due to the absence of hydrologic connectivity to surface waters, they lack legal ...

Biology and control of yellow and knotroot Foxtail 

Joseph, Mikerly Mistral (2023-04-13)  ETD File Embargoed
Setaria pumila Roem. & Schult. (1817 and Setaria parviflora (Poir.) Kerguelen, respectively known as yellow and knotroot foxtail, are two common species infesting turfgrass, pastures, roadsides, and some cropping systems ...

Birdsfoot Trefoil (Lotus corniculatus) Cultivars Adaption Concerning Drought and Heat Tolerance Enabling the Expansion of Geographic Adaptation to include Alabama with Disease Resistance to Fungi and Nematodes as well as Herbicide Injury 

Moye, Hayden Hugh Jr. (2018-11-27)
Lotus corniculatus L., birdsfoot trefoil (BFT), is a common flowering plant in the Fabaceae family, native to grasslands in temperate Eurasia and North Africa. BFT is a perennial herbaceous plant, similar in appearance ...

Boron and Calcium Effects on Runner Peanut Production 

Van Cleave, Ashleigh (2019-04-16)
Calcium (Ca) and boron (B) deficiencies in peanut (Arachis hypogaea L.) reduce seed quality, yield, and crop value. Southeastern U.S. Coastal Plain soils are inherently low in Ca and B, requiring supplementation to reach ...

Characterization of Phosphorus in Poultry Litter and Determination of Phosphorus Extraction Efficacy of Extractants 

Dey, Poulomi (2020-12-10)
Poultry litter (PL) is used as a nutrient source for row crops, horticultural crops, and pasture production. Typically, PL is a mixture of poultry feces, bedding materials, spilled grain and feather than can potentially ...

Closing the Yield Gap in Soybean (Glycine max) with Combined Improved Management Practices 

Hampton, Jamie (2023-08-04)
Food demand is expected to increase by 35% to 56 % by 2050. According to projections by the United Nations Food and Agricultural Organization, global food and feed production needs to increase by 70% by that time to meet ...

Compaction Susceptibility of Select Alabama Piedmont and Upper Coastal Plain Ultisols 

Lane, Abigail S. (2018-11-15)
The U.N. categorizes soil compaction as the most important type of physical soil degradation because of soil productivity and quality loss. Subsoil compaction causes great concern because it is difficult to remediate, ...

A Comparison of Morphological Maturity Methods in Upland Cotton for the Optimization of Crop Production and Breeding Systems 

Peavy, Elliott (2021-12-03)
The indeterminacy of upland cotton (Gossypium hirsutum L.) necessitates methods for evaluating its reproductive status and progress. There is no universally accepted agronomic method for assessing cotton maturity and the ...

Comparison of Poultry Litter and Commercial Fertilizer Rate and Application Timing on Environmental Nitrogen Loss, Corn Grain Yield, and Mineral Composition 

Singh, Rajveer (2020-07-30)
For efficient use of poultry litter (PL) as a nutrient source, it is critical to balance the amount of nitrogen (N) needed to maximize corn (Zea Mays L.) grain yield while reducing N loss to the environment. Besides, there ...
