Liming in Missouri in the 20th century
(University of Missouri--Columbia, Agricultural Experiment Station, 2003)
research on liming conducted by the Missouri Agricultural Experiment Station between 1967 and 1999 and related issues ... Recommended improvements in the recommendation program for agricultural liming materials in Missouri--Page 1....
Soil testing in Missouri : a guide for conducting soil tests in Missouri (2012)
(University of Missouri Extension, 2012)
Soil testing is a process or a group of processes used to estimate the ability of a soil to supply plant nutrients or support plant growth. Soil test results enable evaluation of the fertility status of soil represented ...
A test of differential GPS correction methods at Fort Huachuca, Arizona
(University of Missouri--Columbia, 2009)
in differential correction has previously proven unreliable. The effectiveness of base data acquired through use of a second field unit as an on-site base station was compared with the use of CORS. The accuracy of data differentially corrected using base data...
Factors influencing upland oak advance reproduction in the Missouri Ozarks
(University of Missouri--Columbia, 2011)
in the Missouri Ozarks, we used regression models for estimating the advance reproduction density of red oaks, white oaks, and non-oaks. The abundance of red oak advance reproduction was smaller on northeast-facing slopes and inversely related to soil plant...
Quantifying riparian canopy energy attenuation and stream temperature using an energy balance approach
(University of Missouri--Columbia, 2011)
of the central U.S. Hydroclimate data were collected from two intensively instrumented stream reaches of opposite orthogonal compass orientation in a semi-karst watershed on the border of southern Missouri's Ozark region, USA, during the 2010 water year. Data...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
and water quality and given rise to non-point source pollutants. The claypan soil region of Missouri has a high runoff potential that increases the possibility of transport of non-point source pollutants to downstream sites. The Agricultural Policy...
Recommended chemical soil test procedures for the north central region (2011)
(University of Missouri Extension, 2011)
Land cover classification from satellite imagery, and its applications in cellular network planning
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] To further increase the classification accuracies, radar image processing techniques were investigated to preprocess the Radarsat data before classification. Eight processing...
Long-term study of successional trends in an oak-dominated forest of central Missouri
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Changes in species composition and forest structure were studied over a 36-year period in the Baskett Research and Education Area (BREA) in central Missouri. Permanent plots were...
Economic Vulnerabilities and opportunities of Hispanics in non-metro Missouri
(Cambio Center, 2004)
Non-metro Missouri has observed a net in-migration in the last decennial period and a great part of these immigrants are Latinos. This research addresses the factors explaining vulnerabilities and economic opportunities of Latinos in non...
Wildlife response to spatial and temporal changes in forest habitat
(University of Missouri--Columbia, 2008)
A common goal in land-management planning is to describe the relationship between management actions, vegetation and wildlife habitat conditions for large landscapes. Achieving this goal can be challenging because ecological ...
Creating an imperial city: Kansas City in the 1920s
(University of Missouri--Kansas City, 2011-08-04)
This thesis is a community study of Kansas City in the
1920s as a city working to assume a prominent place within the
emerging American market empire. It begins by exploring the
role that men and women played in altering ...
Atrazine transport through a glacial till aquifer in north-central Missouri
(University of Missouri--Columbia, 2009)
Although the claypan of North Central Missouri is traditionally believed to protect the groundwater from contamination, low concentrations of the herbicide atrazine have been detected in a shallow glacial till aquifer. The fate of the atrazine...
Biomineralizers from the proterozoic to today : assessing taxonomy and paleoecology through the lens of taphonomy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The onset of metazoan predation is presumed to have triggered an evolutionary arms race of prey defenses, including the advent of biomineralization. Escalating biological...
Macroinvertebrate assemblage composition along a longitudinal multiple-land-use gradient in a midwestern stream
(University of Missouri--Columbia, 2012)
Land use changes often alter hydrogeomorphology and hydrologic flow regimes, which can adversely impact stream aquatic biota. Hinkson Creek Watershed (HCW, 231km2) located in Boone County, central Missouri, is comprised of 50% agriculture, 26...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods...
Multi-scale analysis of urban wetland changes using satellite remote sensing techniques
(University of Missouri--Kansas City, 2012-01-10)
This study investigates urban wetland-cover changes in the Kansas City metropolitan area with analyses at various spatial and temporal scales. Not many studies fully addressed multi-scale urban wetland-cover dynamics in ...
The role of terrrestrial habitat in the population dynamics and conservation of pond-breeding amphibians
(University of Missouri--Columbia, 2007)
-structured demographic models for two pond-breeding amphibian species and used these models to determine the potential effects of a range of core terrestrial habitat areas on population size and persistence. I next carried out field experiments designed to improve model...
Canopy recruitment dynamics in naturally regenerated longleaf pine (pinus palustris) woodlands
(University of Missouri--Columbia, 2017)
The ecological and cultural values of the longleaf pine (Pinus palustris) ecosystem, in combination with an approximately 97 percent loss in historic range, has led to increasing interest in ecosystem restoration and ...
