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 ...
Implications for soil health : assessing crop management systems and cover crops on mid-Ohio glaciated soils
(University of Missouri--Columbia, 2016)
Cropping systems management and the presence or absence of cover crops directly influence many physical, chemical, and biological soil properties. The research hypothesis was the use of cover crops and a no-till crop ...
Effects of deep vertical placement of lime on corn and soybean response and soil chemical properties in conservation tillage systems
(University of Missouri--Columbia, 2016)
Soil acidity is one of the most influential factors in limiting crop production around the world. Roughly 30% of the Earth's total land area and as much as 70% of potentially farmable land is affected by soil acidity ...
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 ...
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 ...
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 ...
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- ...
Evaluation of the non-supercell tornado parameter for the green bay, Wisconsin tornado event of 07 August 2013
(University of Missouri--Columbia, 2016)
The difficulty of detecting and forecasting the development of non-supercell tornadoes (NST) is well documented. The rapid, low level development of NSTs decreases the warning time as they often develop in minutes and can ...
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 ...
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 ...
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 ...
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 ...
Enso and PDO climate variability impacts on regional Missouri crop yields
(University of Missouri--Columbia, 2016)
An analysis of crop yields for the state of Missouri was completed to determine if an interannual or multidecadal variability existed as a result of the El Nino Southern Oscillation (ENSO) and the Pacific Decadal Oscillation ...
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. ...
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) ...
Urea fertilizer placement effects on soil greenhouse gas emissions and corn growth
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Agricultural soils are responsible for a majority of human caused greenhouse gas (GHG) production, such as N₂O and carbon dioxide (CO₂). Nitrous oxide ...
The relationship between Mid-west precipitation rates, teleconnections and blocking in the Eastern and Central Pacific
(University of Missouri--Columbia, 2016)
An integral aspect of accurate precipitation outlooks are timely forecasts of teleconnective phase transitions (i.e., the El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO)). Through executing ...
An examination of dual-polarized radar nowcasts and their verification using modern shape analysis techniques
