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; ...
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 ...
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 ...
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 ...
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 ...
Forest harvest effects on soil chemical properties and nutrient concentrations in Ozark Highland soils
(University of Missouri--Columbia, 2010)
Mixed hardwood systems of the Missouri Ozark Forest Ecosystem Project are harvested using clearcutting (CC) and single-tree selection (STS) regeneration methods. This work indicates possible effects of regeneration method ...
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 ...
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 ...
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 ...
The metabolism and localization of glycerol by bovine spermatozoa
(University of Missouri--Columbia, 1958)
Since the discovery that glycerol, a trihydroxy alcohol, would provide protection for spermatozoa during the freezing and thawing process, many questions have arisen concerning its metabolism and mode of action. Most of ...
A Study of the effect of liming an acid soil on the growth of certain legumes and non-legumes
(University of Missouri--Columbia, 1914)
A number of investigators have found that applications of lime to an acid soil have in many cases resulted in a depression of crop yields. This effect has been observed especially in connection with pot cultures where ...
Radar characteristics of tornadic and non-tornadic quasi-linear convective systems over the central United States
(University of Missouri--Columbia, 2014)
Soil hydraulic and physical properties as affected by logging management
(University of Missouri--Columbia, 2014)
Former studies have shown that once compacted, forest soils often recover slowly (many decades) to pre-disturbed levels for soil properties such as bulk density or penetrometer resistance. Runoff and soil erosion from ...
An analysis of the spring-to-summer transition in the west central Missouri Ozarks
(University of Missouri--Columbia, 2014)
The spring-to-summer transition is of special importance in forecasting, as the general circulation undergoes an energy shift to a warmer regime, which affects the Midwestern United States. Beginning at the most localized ...
A study of emergency management policy regarding the use of tornado sirens during severe weather in the state of Missouri
(University of Missouri--Columbia, 2013)
In recent years there have been many devastating tornadoes which have hit cities of all sizes across the state of Missouri, including St. Louis (April 22, 2011) rated EF 4, Joplin (May 22, 2011) rated EF 5 and Sedalia (May ...
A study of the connection between TV meteorologists and their viewers during severe weather broadcasts
(University of Missouri--Columbia, 2013)
After the devastating tornadoes in Joplin, MO and in the Deep South in 2011, it seemed appropriate to look at the impact that broadcast meteorologists (and their TV coverage) have on their viewers during severe weather ...
Apex and fuzzy model assessment of environmental benefits of agroforestry buffers for claypan soils
(University of Missouri--Columbia, 2013)
Contamination of surface waters with pollutants from agricultural land is a major threat to the environment. A field-size watershed study in Northeast Missouri showed that vegetated filter strips containing grass and ...
Rainfall observations using dual-polarization radar coupled with a drop motion and evaporation model
(University of Missouri--Columbia, 2013)
Measuring spatial coverage of rainfall is important for several disciplines; unfortunately, rainfall data via rain gauges is very limited in spatial coverage. The best remote sensing tool available for rainfall estimation ...
