The relation of the size of seed to the character of plant produced
(University of Missouri--Columbia, 1916)
method, altho all have worked with the same general point of view in mind. Montgomery (I9IO) has classified the various methods used at different Stations as follows--Methods of selecting seed. 1. Hand selection. 2. Machine selection. 3. Specific gravity...
The surface tension of soap solutions and their emulsifying power
(University of Missouri--Columbia, 1919)
"In this work, surface tensions of solutions of sodium palmitate and of sodium stearate in contact with air have been determined. These surface tensions were found to increase with decrease in the concentration of the ...
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...
Development and evaluation of a site stormwater analysis calculator intended for the State of Missouri utilzing regional best management practices
(University of Missouri--Columbia, 2023)
impacts for their proposed development and redevelopment scenarios. The calculator utilizes the precipitation data from all weather stations in the State of Missouri reporting data to National Oceanic and Atmospheric Administration (NOAA...
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...
Silage investigation
(University of Missouri--Columbia, 1916)
Abstract derived from the Introduction and Literature sections of the thesis: Ensilage as defined by Webster is the material as it appears while being put into the silo. Immediately after the material is stored it begins ...
Uneven-aged management in the Missouri Ozarks: effects of site conditions, stand density, and prior populations on oak regeneration
(University of Missouri--Columbia, 2022)
While studies have shown the importance of site characteristics and overstory density on the success of white oak regeneration under uneven-aged management, few studies have analyzed the effects of these variables over time in the Missouri Ozarks...
Fire risk assessment of the western portion of the central hardwoods forest region
(University of Missouri--Columbia, 2008)
This study examined how fire risk, a combination of fuels conditions and fire probabilities, varied across a large portion of Missouri, Illinois, and Indiana. Case studies were conducted to evaluate the fuel loading variability in Missouri Ozark...
Quantifying suspended sediment loading in a mid-Missouri urban watershed using laser particle diffraction
(University of Missouri--Columbia, 2011)
/water-quality stations were installed in a nested-scale watershed study design to capture differing land-use type influences on SSC. Mean SSCs were estimated to be 66.0, 70.0, and 86.0 [mu]l/l for the headwater (agricultural), suburban (mixed land-use), and urban sub...
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...
What is the impact of livelihood strategies on farmers' climate risk perceptions in the Bolivian highlands?
(University of Missouri--Columbia, 2009)
The Andean Highland region in Bolivia possesses a harsh climate environment that is highly variable. This study combines risk perception literature and livelihood strategy literature to examine climate risk perceptions. ...
Climate and land use effects on hydrologic processes and water allocation in a primarily rain-fed, agricultural watershed
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] There is a need to raise our understanding of the impact of climate variability and change on hydrologic processes at the watershed scale. This is important, particularly...
Analysis of factors influencing loan losses of production credit associations
(University of Missouri--Columbia, 1974)
reflecting the production and market factors and associated risks, outside business interests that interacted with the kind of enterprise to produce a differential effect on loan losses, and finally, the interaction between education and farming experience...
Effects of light availability and herbivory on planted white oak (Quercus alba) seedlings and acorns
(University of Missouri--Columbia, 2022)
light availability caused by dense forest conditions and damage caused by deer herbivory. The purpose of this study is to analyze the effects of light availability and herbivory on planted white oak seedlings and acorns in Missouri. Data were collected...
Agroforestry and cover crops for improving surface water and groundwater quality
(University of Missouri--Columbia, 2023)
Unsustainable agricultural practices and the rapid expansion of agricultural lands to satisfy the food demand of the growing world population have caused significant sediment, and nutrient losses from agricultural fields, harming the environment...
Behavioral choice and demographic consequences of wood frog habitat selection in response to land use
(University of Missouri--Columbia, 2007)
, Missouri, and South Carolina are determining the effects of timber harvest on the persistence of amphibian populations. The purpose of my dissertation research was to define adult wood frog nonbreeding habitat in continuous oak-hickory forest...
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...
Use of geographic information systems and remote sensing as automated tool for variable rate irrigation prescriptions
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Economic as well as water shortage pressure on agricultural use of water has placed added emphasis on efficient irrigation management. Center pivot technology has made great...
Forging a national diet : beef and the political economy of plenty in postwar America
