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 ... -
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 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 in ... -
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 ... -
Assessing soil carbon and soil quality for sustainable agricultural systems in tropical hillslope soils using spectroscopic methods
(University of Missouri--Columbia, 2017)Soil quality is a concept that integrates physical, chemical, and biological components and processes of soil across landscapes. Identifying and developing appropriate methods to quantify and assess changes in soil quality ... -
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)Knowledge of neonicotinoid sorption and transport in soil is crucial to understanding environmental risk associated with the most widely used class of insecticides. To determine mobility and transport of the neonicotinoid ... -
Soil physical and hydraulic properties affected by topsoil thickness in switchgrass and row crop management systems /
(University of Missouri--Columbia, 2016)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Degraded claypan landscapes can be seen as a potential resource for bioenergy production. Therefore, an important decision needs to be made to determine ... -
The occurrence of extreme monthly temperatures and precipitation in two global regions
(University of Missouri--Columbia, 2017)There has been a lot of focus on the occurrence of extreme weather events and their connection to climate change and variability. Much of this previous work has been related to individual events rather than for mean monthly ... -
Thermodynamic, kinematic, and radar parameters of isolated tornadoes with and without NWS warning
(University of Missouri--Columbia, 2017)Tornadoes are a rapidly forming weather phenomenon that forecasters may have difficulty anticipating. A tornado warning is issued when atmospheric conditions are imminent for formation or a tornado has already formed and ... -
Management of nitrogen and nitrification inhibitors for corn and wheat production on claypan soils
(University of Missouri--Columbia, 2017)Use of nitrification inhibitors (NI) in agricultural production systems is considered a risk management strategy for both agricultural and environmental considerations. It can be utilized when risk of reduced nitrogen (N) ... -
The horizontal redistribution of anomalous vertical heat fluxes at tropical latitudes /
(University of Missouri--Columbia, 2017)A study was conducted to improve quantitative understanding of how anomalous vertical heat fluxes associated with the El Nio-Southern Oscillation (ENSO) are transported poleward to maintain climate equilibrium. State-of-the-art ... -
Soil quality in organic cropping systems
(University of Missouri--Columbia, 2016)The objective of this research was to quantify soil quality indicator levels under contrasting organic practices and to provide scientific information that can lead to development of best management practices for organic ... -
Implications for soil health : assessing crop management systems and cover crops on mid-Ohio glaciated soils
