Risk and stability of phosphate-immobilized lead in contaminated urban soil and mining sites in the Jasper County Superfund Site
(University of Missouri--Columbia, 2007)
In situ application of soluble phosphates and organic matter is considered to be a cost effective remediation technique for immobilizing lead (Pb) and other heavy metals and reducing health and ecological risks associated ...
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 ...
On the synoptic and mesoscale organization of mid-latitude, continental convective snow events
(University of Missouri--Columbia, 2008)
An ingredients-based methodology was pursued in order to evaluate the likelihood of thunderstorms occurring in the presence of snowfall (i.e. thundersnow; TSSN). In order to properly distinguish from typical snowstorms ...
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 ...
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 ...
Analysis of cloud and cloud-to-ground lightning in winter convection
(University of Missouri--Columbia, 2008)
The combination of the full suite of cloud-to-ground (CG) and cloud stroke data is used to observe lightning in precipitation events involving winter precipitation. In particular, we observe data for the winter season of ...
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 ...
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 ...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
Traditional soil mapping concepts do not sufficiently address the spatial resolution of some soil management problems. Continuous models of soil profiles and landscapes are needed to move beyond the categorical paradigm ...
A study of lightning flashes attending periods of banded heavy snowfall
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Lighting[sic] flashes associated with 24 banded thundersnow events were analyzed to document their polarity, signal strength, and multiplicity. Radar ...
Cell identification, verification, and classification using shape analysis techniques
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The use of object-oriented approaches in both the verification of meteorological variables (especially precipitation) and the short-term forecasting ...
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 ...
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 ...
Utilization and limitations of soil health metrics in Missouri corn production decisions
(University of Missouri--Columbia, 2022)
Soil health benefits are widely acknowledged but empirically-vetted connections to agronomic outcomes remain absent. Therefore, recommendations for on-farm soil health assessments and interpretation remain ambiguous. ...
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; ...
Historical rainfall analysis and climate implications for agriculture in midwest United States
(University of Missouri--Columbia, 2021)
A historical analysis of precipitation using 72 years of data from Midwest stations focuses on the implications of climate change for agricultural interests. The number of precipitation events, consecutive days of ...
Assessing fall velocity-maximum dimension relationships and particle size distributions for snowfall
(University of Missouri--Columbia, 2021)
Snowfall is an atmospheric phenomenon that can cause significant impacts to many aspects of daily life in Missouri. Further, no two snowfall events are exactly the same, as even small differences in environmental characteristics ...
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 ...
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 ...
