Application of a digital terrain model for forrest land classification and soil survey
(University of Missouri--Columbia, 2004)
Land characterization and classification is central to sound natural resource management. Forest land classifications usually lack sufficient detail, are not scale-adjustable, and are limited in scope and applications for ...
Rhizobacteria associated with glyphosate-resistant soybean (Glycine Max)
(University of Missouri--Columbia, 2006)
The research was conducted to examine the impact of GR soybean treated with glyphosate on rhizobacterial activities involved in IAA production and soil C and N mineralization in different soil management systems; to determine ...
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 ...
Use of slow-release N fertilizer to control nitrogen losses due to spatial and climatic differences in soil moisture conditions and drainage in claypan soils
(University of Missouri--Columbia, 2006)
Agricultural soils are a major source of nitrous oxide (N₂O) which has a significant environmental impact on global warming and ozone depletion. However, there is little information on soil N₂O emissions under different ...
Adsorption of isoxaflutole degradates to hydrous aluminum and iron oxides
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Isoxaflutole (IXF) is a pre-emergence herbicide that is rapidly transformed to a more stable and soluble diketonitrile degradate (DKN) after field ...
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 ...
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 ...
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 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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Scale and stability analysis of selected atmospheric blocking events
(University of Missouri--Columbia, 2008)
Global six year climatology of mid latitude atmospheric blocking events, during the period 1999-2004, is presented based on the scale and stability analysis, using the NCEP/NCAR re-analysis data. A total of 278 blocking ...
