Soil microbial response to land management practices and wildfire in Appalachian ecosystems
… communities change as a result of different land management practices or natural disturbances can provide insight into the effects of these perturbations on ecosystem health, such as water quality and organismal growth. The studies presented in this thesis address how relevant land management …

Impact of Manure Land Management Practices on Manure Borne Antibiotic Resistant Elements (AREs) in Agroecosystems
… primarily with livestock rearing. Animal manure land application integrates livestock farming and agroecosystems. This manure contains antibiotic resistant elements (AREs) (resistant bacteria, resistance genes, and veterinary antibiotics) that contribute towards antimicrobial resistance. Altering …

Understanding the relationship between agricultural nutrients NPS, land management, and climate using distributed hydrologic models
… nutrient loading in our water bodies, different land management schemes have been developed and implemented to reduce N and P NPS in the agroecosystem, but the effectiveness of these land management practices needs evaluation. Due to the complexity of the watershed response to natural and …

Estimation of the global carbon fluxes due to agricultural management activities using a land surface model (ISAM)
… from the agriculture sector. This study uses a land surface model with spatially heterogeneous representations of agricultural land management practices to estimate the carbon dynamics induced by agricultural land management practices (i.e., planting crops, fertilization, irrigation, harvesting, …

A GIS-Based Watershed Impact Management Model
<p>Assessment of land use changes on hydrological processes is essential for the planning and development of sustainable land management practices and water resources. Understanding how land management practices influence hydrological components is essential for the prediction of hydrological …

The Relationship of Small Mammal Species to Habitat Variables in West-Central Georgia and East-Central Alabama
… microhabitat characteristics due to training or land management practices would change the distributions of several species. The four most important environmental variables with respect to how the small mammals responded to them were understory, canopy cover, the number of deciduous species, and …

Assessing belowground biomass changes following land management and vehicle disturbance
… of military training on vegetation into their land carrying capacity models. An understanding of the impacts and methods to reduce impacts would increase training throughput, minimize costs, and improve training realism. This study is the beginning of an effort to understand the otherwise …

Isotopic evidence for the cycling of nitrate and nitrous oxide in aquifers beneath an irrigated agricultural district using established and emerging measurement techniques
… controls on NO3- and N2O, leading to improved land management practices. Although most groundwater isotopic measurement techniques are well-established, laser spectroscopic methods to acquire groundwater N2O isotopic data are still evolving. However, if proven robust, they may provide potential …

The quantification and characterization of soil carbon pools in biofuel agriculture.
… opportunity to study and implement sustainable land management practices that improve soil health and a deeper understanding of mechanisms involved in terrestrial carbon cycling. Agricultural land management strategies such as fertilization, tillage, and crop selection affect soil organic carbon …

Erosion and nutrient loading characteristics of two small agricultural watersheds in Piedmont Virginia
… were contrasted between the two watersheds whose land management practices differed. A comparison between years was also made on the conservation watershed, where part of the conservation plan was abandoned the second year. The use of conservation practices resulted in smaller estimates of gross …
