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...
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 ...
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...
Impacts of suspended and deposited sediment on benthic invertebrates and fishes in a Missouri Ozark stream
(University of Missouri--Columbia, 2006)
Sediment is suspected in the decline of sensitive-aquatic organisms in the Osage River basin of Missouri. In this study, I monitored sediment dynamics and evaluated corresponding linkages with benthic invertebrate and fish assemblages as it related...
A test of differential GPS correction methods at Fort Huachuca, Arizona
(University of Missouri--Columbia, 2009)
acquired from an on-site base station showed marked improvement over the use of CORS base data. Accuracy of locally corrected points improved by 75cm and 95cm in two study areas as compared to uncorrected data, while accuracy actually degraded by 28cm and 1...
Dry milling characteristics and polyphenolic contents of adapted colored corn varieties and polyphenol extraction by combining deep eutectic solvents and ultrasound
(University of Missouri--Columbia, 2023)
, hesperidin, and chlorogenic acid, the highest values being 3.29, 1.72, 0.63, 15.18, and 5.23 mg/g pericarp, respectively. Finally, epicatechin, naringin and kaempferol concentrations of 102.73, 19.93, and 1.55 mg/g pericarp, respectively, were eluted during...
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...
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...
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...
Establishing pin oak reproduction in bottomland forests in southeastern Missouri
(University of Missouri--Columbia, 2010)
In pin oak (Quercus palustris Muenchh.) bottomland forests in southeast Missouri, we revisited clearcuts, shelterwood harvests, and controls within the Mingo Basin. Seventeen years later, we found significant changes, in both the change in basal...
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...
Detection of cold flow properties of diesel and biodiesel fuel using optical sensor
(University of Missouri--Columbia, 2006)
of transmittance for all blends of biodiesel is 0.3 or lower....
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...
Plant community response during establishment of woodland silvopasture in the Missouri Ozarks
(University of Missouri--Columbia, 2022)
Disturbance-mediated oak (Quercus spp.) woodlands were formerly a prevalent community type in Missouri, and their restoration is a key objective of land management agencies and conservation organizations. Over one-third of wooded land in Missouri (2...
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...
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...
Alternative learning strategies for spatio-temporal processes of complex animal behavior
(University of Missouri--Columbia, 2020)
The estimation of spatio-temporal dynamics of animal behavior processes is complicated by nonlinear interactions. Alternative learning methods such as machine learning, deep learning, and reinforcement learning have proven ...
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
Agriculturally produced ethanol, a renewable resource, may be reformed noncatalytically into hydrogen by a novel process utilizing supercritical water, which acts synergistically both as a solvent and as a reactant. By utilizing supercritical water...
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...
