Classification of air pollution regimes in the Missouri region
(University of Missouri--Columbia, 2009)High levels of ground level ozone have been linked to large-scale weather patterns both at the surface and in the upper atmosphere. For this reason, the main focus of this study was to analyze the atmospheric conditions ... -
Climatology of atmospheric blocking 1978-2008 : global and hemispheric breakdown, as well as impacts of temperature, and global climate cycles
(University of Missouri--Columbia, 2010)An examination of atmospheric blocking from the years 1978-2008 was conducted to explore the impacts of temperature and climate cycles on blocking intensity, blocking duration, and total blocking events on an annual basis. ... -
The climatology of dew points and fire weather related parameters in the Missouri-Arkansas region
(University of Missouri--Columbia, 2010)Forecasting fire weather in the Springfield, Missouri and Little Rock, Arkansas Weather Forecast Offices (SGF and LZK WFO, respectively) across the greater Missouri and Arkansas regions (MoArk) county warning areas has ... -
Comparison of rainfall energy and soil erosion parameters from a rainfall simulator and natural rain
(University of Missouri--Columbia, 2007)Numerous studies have used artificial rainfall to quantify relationships for runoff and soil detachment. Application of these results to natural rainfall conditions is dependent in part on how well artificial rainfall ... -
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 ... -
Cover crop practices in Missouri claypan soils and their influences on selected soil health indicators
(University of Missouri--Columbia, 2015)Growing world human populations and diversified global markets have increased demand for agricultural food products, as well as non-food agricultural industry products. To meet these expected future demands, increasing and ... -
Cover crops : an alternative practice to improve soil physical properties and soil water dynamics
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cover crop management practices have emerged in the past decades as an alternative to improve soil physical, biological and chemical properties by ... -
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)Water and soil are two key elements for life on this planet, and improving and preserving their quality are of prime importance. Various human actions including use of intensive chemicals in agriculture have accelerated ... -
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 ... -
Discrimination of elevated convection based on low-level radar-derived convergence
(University of Missouri--Columbia, 2016)Elevated convection has now been widely associated with severe hazards such as large hail and heavy rainfall, however, high winds and tornadoes are not as common (e.g., Grant 1995, Moore et al. 2003, Horgan et al. 2007). ... -
Effects of a consortia probiotic inoculant on soil microorganisms and impacts on autoinducers employed in quorum sensing
(University of Missouri--Columbia, 2013)Disease control in plant agriculture is largely achieved through application of various antimicrobials. Manipulation of indigenous soil microbial communities received attention as it promises improved pathogen control and ... -
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 ... -
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 ... -
Effects of selected surfactants on nutrient uptake and soil microbial community
(University of Missouri--Columbia, 2011)Surfactants with solvent and wetting abilities are used in the formulation of herbicides to enhance spraying capabilities. These chemicals eventually enter into the soil and may disrupt different chemical, physical and ... -
Effects of veterinary antibiotics on atrazine degradation in soil
(University of Missouri--Columbia, 2014)The release of veterinary antibiotics (VAs) in the environment is concerning because VAs have been linked to the development of antimicrobial resistant bacteria and may influence nutrient cycling and agrochemical degradation. ... -
Elemental concentration changes in soil and stockpiled tall fescue leaves after liming
(University of Missouri--Columbia, 2006)Tall fescue (Festuca arundinacea Schreb.) is the dominant forage in Missouri and grows primarily on acidic soils that possess little plant available phosphorus (P). Little is known about the effects of lime on the elemental ... -
Enhanced efficiency phosphorus application for corn
(University of Missouri--Columbia, 2012)Farmers are interested in the use of enhanced efficiency phosphorus (P) fertilizer applications or treatments. The objectives of this research are (1) to determine the effects of tillage/fertilizer placement [no-till ... -
Enhanced rhizodegradation of munitions explosives and degradates by selected native grass species
(University of Missouri--Columbia, 2010)TNT (2,4,6-trinitrotoluene) and RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) are the two most widespread explosives in the world. The manufacture, use and disposal of explosives can result in environmental contamination, ... -
Enso and PDO climate variability impacts on regional Missouri crop yields
