Impacts of nitrogen fertilizers and nitrification inhibitors on greenhouse gas emissions from soil
(University of Missouri--Columbia, 2024)[EMBARGOED UNTIL 08/01/2025] This thesis investigates the impact of nitrification inhibitors and varying fertilizer rates on greenhouse gas emissions and crop yield in agricultural systems. Fertilized agricultural soils ... -
Cycles and drivers of spatiotemporal variation of forest soil respiration at the intra-landform scale
(University of Missouri--Columbia, 2024)Spatiotemporal variability of soil respiration (RS) is a primary driver of large uncertainties associated with forest carbon budgets. However, most studies focus on either spatial or temporal variations, not both. As the ... -
Drought impacts on forest responses to precipitation and biological drivers of the surface energy imbalance
(University of Missouri--Columbia, 2024)The eddy covariance (EC) technique is used across the world to study the interaction between the biosphere and the atmosphere. This thesis consists of two research chapters, one devoted to analyzing historical EC data to ... -
Evaluation of soil properties in log landings after subsoiling and biochar amendments
(University of Missouri--Columbia, 2024)[EMBARGOED UNTIL 05/01/2025] Log landings are a necessary component of timber harvest infrastructure that decrease overall impact of harvest activities by concentrating management operations to a small area. However, the ... -
Identifying cold-air damming in the region of the Ozark Plateau
(University of Missouri--Columbia, 2024)Following the events of March 2014 in which icy, hazardous conditions stranded motorists along the roadways and interstate highways of eastern Arkansas, an investigation is launched to determine if the event was the result ... -
The evaluation of drop size distrubutions captured by two weather radars in mid Missouri
(University of Missouri--Columbia, 2022)In 2015, an X-band dual-polarization Doppler radar (MZZU) was installed in Columbia, Missouri. Its goal is to fill a gap in radar coverage and provide a precipitation climatology for Mid-Missouri. MZZU captures precipitation ... -
Effects of prescribed fire on forest soil properties in the Ozark Highlands
(University of Missouri--Columbia, 2020)Prescribed fire is commonly applied to meet a variety of forest management objectives, including the restoration and maintenance of Oak (Quercus spp.) woodlands. In the Ozark Highlands, private landowners, conservation ... -
Playa wetland plant and soil response to predicted climate and land use change in the southern Great Plains
(University of Missouri--Columbia, 2019)"To assess potential risks to playas in a changing climate, weaddressed the following objectives: (1) quantify effects of changing climatic conditions on plant germination and community composition, soil chemistry, greenhouse ... -
A review of Bayesian belief network models as decision-support tools for wetland conservation : are water birds potential umbrella taxa?
(2018)Creative approaches to identifying umbrella species hold promise for devising effective surrogates of ecological communities or ecosystems. However, mechanistic niche models that predict range or habitat overlap among ... -
Quantifying evaporation of precipitation below the cloud base using a vertically pointing radar
(University of Missouri--Columbia, 2019)Evaporation is the transformative process by which liquid water becomes water vapor. This is a very complex process that many times gets parameterized or even omitted in model forecasting. Previous work has been undertaken ... -
Cover crop effects on corn plant water uptake and soil health
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Cover crops (CC), close growing crops that provide soil and seeding protection between periods of normal cash crop production or between trees ... -
Anthropogenic effects on soil physical, chemical, and biological properties in the Missouri Ozarks
(University of Missouri--Columbia, 2018)The maintenance of healthy forest ecosystems is critical to ensuring the sustainability of forest harvest activities. Forest soil health is a critical component of the knowledge required to manage a forest ecosystem; ... -
Detection of gust fronts using the doppler velocity derived divergence product
(University of Missouri--Columbia, 2018)Identifying gust fronts can be essential for situational awareness when developing nowcasts during convective events. In addition to bearing potentially damaging winds, gust fronts also act as forcing mechanisms; influencing ... -
Influence of residue management on soil chemical properties and nutrient flux in forests harvested for woody biomass
(University of Missouri--Columbia, 2014)Altered soil solution chemistry and nutrient flux within forests harvested for woody biomass may result from disturbance, slash removals, slash decomposition, and mineralization. Because of the potential adverse effects ... -
Identification and characterization of atrazine-degrading phytochemicals in eastern gamagrass
(University of Missouri--Columbia, 2014)Naturally occurring phytochemicals of the 1,4-benzoxazin-3-one (Bx) class exhibit broad chemical reactivity that includes detoxification of chloro-triazine herbicides. Atrazine (6-chloro-N-ethyl-N’-(1-methylethyl)-1,3,5- ... -
Influence of cover crop and tillage management practices on soil physical and hydraulic properties
(University of Missouri--Columbia, 2017)Several agricultural land management practices, such as cover crops and tillage, can influence soil physical and hydraulic properties, soil health indicators and crop productivity. This study evaluated the influence of ... -
Measuring and modeling rainfall with terrestrial sensors and radar : implications for rainfall heterogeneity and discharge
(University of Missouri--Columbia, 2017)Quantitative precipitation estimates are fundamental for hydrometeorological analyses. Radars provide a superior spatiotemporal advantage over terrestrial-based precipitation gauges to provide such measures of rainfall. ... -
A study of elevated convection and its impacts on surface weather conditions
(University of Missouri--Columbia, 2017)Elevated convection is a vexing phenomenon that causes forecasting problems for both numerical weather prediction systems and human forecasters alike. It is frequently associated with heavy rain and can produce flash ... -
