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 of greenhouse studies...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
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...
Nutrients, chlorophyll and bacterial fecal indicators in coves and open water areas of Lake of the Ozarks, Missouri
(University of Missouri--Columbia, 2009)
the specificity of conventional fecal indicators (FC and EC). Discharges 3-4 times the average were recorded for both summers. Relationships between anthropogenic indices and water quality variables (TP, TN, Chl, FC and EC) were not apparent, likely because...
Analysis of factors influencing loan losses of production credit associations
(University of Missouri--Columbia, 1974)

The potential of producing bioenergy crops on conservation reserve program land in Missouri, Iowa, Nebraska, and Kansas (MINK Region) to mitigate carbon dioxide emissions : an integrated economics and biological modeling approach
(University of Missouri--Columbia, 2010)
policymakers develop sustainable and balance of energy-agriculture-environmental policies....
Importance of agritourism for agripreneur goal accomplishment
(University of Missouri--Columbia, 2010)
associated with the importance of agritourism in accomplishment within four goal dimensions via descriptive-relational survey research. Agritourism farms in Missouri are in the business of agricultural production, rather than maintaining their land...
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...
Interactions between cover crops, herbicides and weeds in soybean production systems
(University of Missouri--Columbia, 2018)
. An identical field experiment was conducted in 2016 in Arkansas, Indiana, Missouri and Wisconsin and repeated in Arkansas, Indiana, Mississippi and Missouri in 2017 to evaluate the most effective herbicide treatments for spring termination of regionally...
