to identify all references to agriculture within the textbook. All references were categorized according to the agricultural literacy areas as defined by Frick, Birkenholz, and Machtmes (1995). Text references were coded as reports, inferences, judgments...
Modeling the influence of climate and management practices on water quality in Goodwater Creek experimental watershed
(University of Missouri--Columbia, 2006)
The objective of this study was to determine relationships among weather, runoff, water quality, and best management practice (BMP) implementation in reducing atrazine losses in the 7,250-ha Goodwater Creek Experimental Watershed in NE Missouri...
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...
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...
Personality type as a predictor of interaction between student teachers and cooperating teachers
(University of Missouri--Columbia, 2005)
-2004 school year, from the University of Missouri-Columbia and University of Illinois at Urbana-Champaign, participated in the study.The study was descriptive-correlational, quantitative research. To measure personality type, the Myers-Briggs Type Indicator...
Evaluation of soy hulls as the principal ingredient in a beef cattle receiving ration
(University of Missouri--Columbia, 2005)
Adjusting cattle to grain based diets from predominately forage diets remains one of the production problems facing beef cattle producers. When cattle are introduced to grain based diets they have a tendency to experience health problems...
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...
Three essays on food security, agricultural productivity, and commodity basis
(University of Missouri--Columbia, 2021)
The proposed research is constructed around the theme of food security, agricultural productivity, and commodity basis. The first paper analyzes the impacts of COVID-19 on the Bangladesh rice market within the framework of a partial equilibrium...
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...
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...
Entrainment and transport of coarse stream bed material in a fluviokarst watershed, south-central Missouri : a tracer particle study
(University of Missouri--Columbia, 2010)
of the longitudinal movement of tracers over a 10-month period indicate that minor amounts (0-13.2%) of coarse bed material in TCC are mobilized by relatively low flows (5-28% of bankfull) that recur somewhat frequently (less than 3.1 years). BCH transports a higher...
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...
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...
An assessment of the light and nutrient regimes constraining phytoplankton dynamics in Missouri reservoirs
(University of Missouri--Columbia, 2021)
Worldwide, nutrient pollution, or eutrophication, is one of the most pervasive environmental issues threatening water quality. Anthropogenic influences, primarily urbanization and agriculture, have drastically increased inputs of bioavailable...
