Perceptions of secondary agriculture teachers and 4-H youth development extension personnel regarding cooperative behavior
(University of Missouri--Columbia, 2008)
and types of cooperation that occur between secondary agriculture teachers and 4-H youth development personnel in Missouri. Secondary agriculture teachers and 4-H youth development personnel acknowledge cooperation is important for secondary agricultural...
The social economics of organic production in Columbia's Farmer's Market
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The research involves preliminary field investigation of the impacts of social demands on economic decisions made by producers, such agricultural management among farmers...
Reflectance sensors to predict mid-season nitrogen need of cotton
(University of Missouri--Columbia, 2008)
Nitrogen (N) is an essential nutrient for cotton production; consequently there is a tendency to over-apply nitrogen. High N causes excessive vegetative growth and delayed crop maturity, which result in increased cost in ...
The family farm in the post-World War II era : industrialization, the cold war and political symbol
(University of Missouri--Columbia, 2008)
This dissertation examines the particular path of technological change after World War II, how farm people adjusted to that change in their work and identity, as well as the policy implications of the numerous ramifications ...
Visitor experiences at Eagle Days in Missouri
(University of Missouri--Columbia, 2010)
Missouri since the winter of 1978-1979, only one formal study has been conducted on these events and it was after the first year. The purpose of this research is to evaluate visitors' perceptions of Eagle Days events in Missouri using the experience economy...
Seasonal variation in nutrient availability and uptake by oak saplings following four nitrogen treatments on Missouri River floodplain
(University of Missouri--Columbia, 2008)
Bottomland restoration of native hardwood species provides a variety of benefits to the environment and the landowners. However, when reforesting agricultural floodplains along the Missouri River, high soil pH often causes nutrient deficiencies...
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...
A multi-scale investigation of ecologically relevant effects of agricultural runoff on amphibians
(University of Missouri--Columbia, 2008)
Modification of landscapes for agricultural production can introduce agrochemicals into surface waters and degrade aquatic habitats used by many amphibians for breeding and larval development. Although many ecotoxicological studies have shown...
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...
Development of implementation methods of water quality trading policy : using the Hydrological simulation program-Fortran (HSPF)
(University of Missouri--Columbia, 2010)
-fortran (HSPF) was used to estimate the hydrology and sediment loading throughout the Brush Creek, MO watershed for future land use development scenarios between upstream and downstream locations. Brush Creek does not have a proper monitoring station...
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....
Alternative tillage and nitrogen management options to increase crop production and reduce nitrous oxide emissions from claypan soils
(University of Missouri--Columbia, 2010)
The Central Claypan Region covers an area of 10 million acres of claypan or claypan-like soil in Missouri, Oklahoma, Kansas, Iowa, and Illinois. Agricultural production on claypan soil can have lower yield and a greater impact on the environment...
A comparison of grant-funded outdoor classrooms in rural and nonrural Missouri schools
(University of Missouri--Columbia, 2009)
This study addressed the question: How do outdoor classrooms in rural and nonrural areas of Missouri compare? Data was collected from applications for state funded grants awarded from 2004- 2006 to elementary schools in rural and nonrural areas...
A multi-configuration evaluation of the soil and water assessment tool (SWAT) in a mixed land use watershed in the central U.S.A.
(University of Missouri--Columbia, 2011)
. Watershed and soil resolution had negligible impact; climate input had considerable impact. Single climate station input is best used for applications requiring monthly predictions; distributed climate station input is needed for daily predictions. SWAT...
Beyond the edge : riparian habitat use and forest management effects on stream salamanders in the southern Appalachian mountains
(University of Missouri--Columbia, 2007)
While there are many types of habitat loss and degradation (e.g., agriculture, land development), many studies have focused on the impacts of logging on wildlife populations and on ecosystem processes. Little information, however, exists...
Estimation of total height, growth, and mortality of forest trees in Missouri
(University of Missouri--Columbia, 2005)
A model for predicting total tree height as a function of tree diameter was calibrated for twelve tree species common to the Missouri Ozarks. Model coefficients were derived from nearly 10,000 observed trees. The calibrated model did a good job...
River restoration in the upper Mississippi River Basin
(University of Missouri--Columbia, 2006)
River restoration has become an important management choice to address causes and effects of surface water impairment and river modification in the Upper Mississippi River Basin (UMRB). I report information on individual UMRB river restoration...
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...
Determining the efficacy of a biosensor to detect calpastatin, a meat tenderness indicator
(University of Missouri--Columbia, 2007)
An instrumental tenderness detection system used at the time of grading to sort beef carcasses on their predicted tenderness would be valuable for the beef industry. A biosensor to accurately predict calpastatin, the ...
Ferns as a forest farming crop: effects of light levels on growth and frond quality of selected speicies with potential in Missouri
(University of Missouri--Columbia, 2006)
In Missouri 11.3 million acres of commercial forests are privately owned. The vast majority is under very little - if any - management. Agroforestry, specifically forest farming, has the potential to provide producers an opportunity to put...
