Optimizing crop N use efficiency using polymer-coated urea and other N fertilizer sources across landscapes with claypan soils
(University of Missouri--Columbia, 2008)
Development of improved management practices to increase nitrogen use efficiency (NUE) within agricultural fields is needed to improve crop production and reduce nitrogen (N) loss. Field studies planted to maize were ...
Evaluating and improving the performance of radar to estimate rainfall
(University of Missouri--Columbia, 2008)
A network of 10 rain gages reports data from the Goodwater Creek catchment in central Missouri. Because such a network is expensive to operate, it could be useful instead to use only a few gages and augment the observations ...
A formal evaluation of storm type versus storm motion
(University of Missouri--Columbia, 2008)
In order to predict the location of heavy storm-generated rainfall that could produce flash flooding, forecasters want to know with what velocity a storm will move. However, few systems exist in meteorology where a storm ...
Two extreme cases of atmospheric blocking over Europe and North America
(University of Missouri--Columbia, 2007)
Atmospheric blocking is simply the inhibition, on the synoptic and planetary scale, of the normal mid-latitude progression of migratory cyclones and anticyclones. While the block itself is readily observable as a 500-hPa ...
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 ...
A tall tower wind investigation of northwest Missouri
(University of Missouri--Columbia, 2007)
With energy needs on the rise and our current energy consumption methods polluting the atmosphere, it is the right time to look at alternative forms of energy production. Six Tall Tower wind observation sites were studied ...
Use of different sources and rates of foliar potassium with glyphosate to overcome environmental- and management-induced K deficiency in soybeans
(University of Missouri--Columbia, 2007)
The incidence of potassium (K) deficiency in soybeans [Glycine max (L.) Merr] has increased over the last few years in Missouri and other Midwestern states. Postemergence application of foliar K fertilizer would have the ...
Impacts of municipal wastewater effluent on seed banks, chemistry, and microorganisms of soils excavated from wetland impoundments designated for wildlife
(University of Missouri--Columbia, 2009)
To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set ...
Streambank erosion and risk assessment of contaminant transport in Missouri watersheds
(University of Missouri--Columbia, 2010)
Sedimentation and herbicide are significant water quality concerns in claypan watersheds. Two separate watershed-scale studies were conducted in the Central Claypan Region of northeastern Missouri. One project investigated ...
Analysis of forecast performance for hit, miss, and false alarm thundersnow events during ROCS
(University of Missouri--Columbia, 2010)
Thundersnow (TSSN) is a mesoscale event that is typically associated with large amounts of precipitation and both in-cloud and cloud-to-ground lightning. Starting in 2003, the Research on Convective Snows (ROCS) group began ...
The massive tornado outbreak of May 2003
(University of Missouri--Columbia, 2005)
In May of 2003, 516 tornadoes touched down in the central portion of the United States, which is a record for the most tornadoes for any single month. There were fourteen deaths associated with those tornadoes that touched ...
Infrared and passive microwave satellite rainfall estimate over tropics
(University of Missouri--Columbia, 2005)
Precipitation is an important but highly variable atmospheric parameter. Existing rain gauge networks and weather radar cannot provide the temporal and spatial coverage that is needed to monitor it sufficiently. Thus, ...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
Forecasting heavy rain events and the area of greatest threat has been a long standing challenge in operational meteorology. This is especially true in certain regions where the physical geography lends itself to the ...
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; ...
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 ...
Investigating near-surface wind fields as influenced by low-level jet occurrences in Missouri
(University of Missouri--Columbia, 2009)
Renewable energy sources remain a topic of increasing importance in today's society. One possible source is the utilization of wind energy. As such, the objectives of this study were to investigate and classify the character ...
An investigation into the contribution of the low-level jet (LLJ) to the available wind resource in Missouri
(University of Missouri--Columbia, 2009)
This work uses data (1 September 2006-31 August 2007) from a network of tall-towers to investigate the impact of the nocturnal low-level jet (LLJ) on near-surface winds in Missouri. Of particular interest is the contribution ...
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 ...
Impacts of soil management practices on soil fertility in potato-based cropping systems in the Bolivian Andean highlands
(University of Missouri--Columbia, 2010)
Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in ...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
