Ammonium Thiosulfate and Potassium Thiosulfate as Potential Nitrification Inhibitors in Soils
Galloway, Lane (2024-03-12)
Nitrogen use efficiency (NUE) can vary according to soil properties, precipitation, and
soil temperature. Nitrification inhibitors show potential to increase NUE by decreasing the
amount of N lost from leaching and ...
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 ...
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 ...
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 ...
Cover Crop Effects on Insect Dynamics in Cropping Systems of the Southeastern U.S.
Akins, Joseph (2020-11-16)
Evidence suggests winter cover crops could be useful for augmenting conservation biological control of insect pests in southeastern row crop systems. Management decisions such as selection of cover crop species and irrigation ...
Cover Crop Effects on Urease Inhibitors
Hull, Noah (2018-07-23)
Urease inhibitors continue to be introduced in the agricultural market, and thus new studies with these products are warranted. The objective of this research was to examine the utility of these inhibitors for reducing ...
Cover Crop Management Practices to Improve Soil Health and Weed Suppression in Cropping Systems
Reiter, Wade (2023-11-27)
Introducing integrated crop-livestock systems into row crop production may provide incentives for producers to plant cover crops and promote soil health benefits on degraded soils of the southeastern United States, but ...
Efficacy and Antagonism of Pinoxaden Alone and in Combination with Other Pesticides for Annual Grass Control
Peppers, John (2019-11-14)
Pinoxaden is an acetyl coenzyme A carboxylase (ACCase) inhibiting herbicide in the phenylpyrazoline chemical family. Recently, pinoxaden was labelled for turfgrass use with a limited number of labelled susceptible weeds. ...
Evaluating the effects of soil tillage on ground nesting bees in the southeastern United States
Cuminale, Anthony (2023-12-04)
Pollination by native bees is an economically and ecologically valuable service, necessary in both agricultural and natural landscapes. The majority of bee species nest below ground, an aspect of their biology that raises ...
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 Integrated Weed Management and Herbicide Tolerance in Peanut-Cotton Rotation
Price, Katilyn (2021-07-13)
As resistant weeds such as Palmer amaranth (Amaranthus palmeri L.) continue to spread through the Southeast, peanut-cotton producers are forced to utilize herbicides which pose a greater risk to injuring crops to control ...
Evaluation of Irrigation Scheduling and Sustainability Indicators as Tools to Increase the Adoption of Conservation Practices Among Central Alabama Farmers
Duarte de Val, Marina (2023-11-27)
In recent years, there has been a significant surge in the adoption of conservation practices in agriculture, driven by a collective understanding of the urgent need to minimize risks, enhance profitability, and protect ...
EVALUATION OF NITROGEN SOURCES FOR ALABAMA COTTON PRODUCTION SYSTEMS
Rose, Evan (2022-05-16)
Cotton is the most-widely produced cash crop in Alabama, with an average of 415,000 acres per year planted during the 2011-2020 growing seasons. Nitrogen (N) is often the most limiting nutrient in cotton production systems ...
Impacts of Winter Grazing on Soil Health in Southeastern Cropping Systems
Crowell, Hayley (2020-11-16)
Coastal Plain soils are often characterized by low soil organic carbon as a result of historically intense row cropping practices, highly weathered soils, and the humid climate of the region which often breaks down organic ...
Improved Understanding of Mitotic-Inhibiting Herbicide Resistance in Poa annua and Eleusine indica
Russell, Eli (2021-04-12)
Poa annua is a problematic weed that infests golf courses, sports fields, and home lawns. Mitotic-inhibiting herbicides are often used to control Poa annua in these affected areas. However, resistance to mitotic-inhibiting ...
Influence of Cover Crop Mixtures on Soil Health and Weed Control in Cotton Production Systems
Johnson, Anna (2020-03-06)
The restoration of soil health is a crucial step in maximizing productivity in the
historically-eroded Ultisols of the Southeast. The utilization of winter cover crops can
potentially improve soil health by increasing ...
Influence of Cover Crops and Fertility Management on Soil Health and Soil Microbial Community
Decker, Hannah (2021-11-19)
The southeastern United States has a long history of soil degradation due to intensive agriculture, and conservation agriculture practices aim to improve soil productivity. Conservation management practices include nutrient ...
