agriculture instructors in teaching concepts related to science; 2) To assess how such a change in the curriculum would impact current agricultural education programs. The sample was derived from the population of agriculture instructors teaching in Missouri...
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...
Biomass Burning and Its Relationship with Water Cycle Dynamics of the Chari-Logone Catchment of Lake Chad Basin
(University of Missouri -- Kansas City, 2018)
The present study investigates the effect of biomass burning on the water cycle dynamics of the Chari-Logone catchment, which is the primary water source of Lake Chad, in central sub-Saharn Africa, providing approximately ...

(University of Missouri--Columbia, 2019)
survival and growth rates of planted shortleaf pine relative to artificial and natural hardwoods, identify barriers to regeneration success, and develop tools for individual tree assessment. Data from three long-term studies in southeastern Missouri were...
Roadway effects on the hydrologic regime of temporary wetlands in the Missouri River floodplain in Missouri
(University of Missouri--Columbia, 2005)
on the hydrologic regime of temporary wetland basins within the agricultural landscape of the Missouri River floodplain from Hartsburg to Independence, Missouri. This study is part of a larger existing research project designed by the Missouri Department...
Response of natural and artificial pin oak reproduction to mid- and understory removal in a bottomland hardwood forest
(University of Missouri--Columbia, 2006)
bottomland forest sites in southeastern Missouri. The mid- and understory removal treatment increased the amount of photosynthetically active radiation reaching the understory from 3 percent of full sunlight to 16 percent of full sunlight. This increase...
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...
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...
Flood potential of Poyang Lake, China
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Poyang Lake, located in Jiangxi Province, China, is a large freshwater lake ([about]4000 km[superscript 2]) connected to the Yangtze River. Flooding hazards in Poyang Lake...
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...
Geostatistical analysis of land use/land cover changes and population growth trends in the Komadugu-Yobe River Basin in Nigeria
(University of Missouri-Kansas City, 2012-06-14)
The Komadugu-Yobe River located in northeastern Nigeria is an important tributary of Lake Chad. Since the 1970s, the Komadugu-Yobe basin has experienced significant changes in population density and land use/land cover. ...
Effect of irrigation on fertilizer nitrogen requirement, economic returns, and water availability in a corn-soybean rotation
(University of Missouri--Columbia, 2019)
application. Two irrigation experiments were conducted at University of Missouri Greenley Research Center near Novelty, MO from 2015 to 2018. In each experiment, three irrigation treatments: sprinkler irrigation, subsurface drip irrigation, and no...
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...
Distribution and abundance of anurans in southeast Missouri
(University of Missouri--Columbia, 2005)
Studies were conducted on 15 1034 ha landscape blocks to investigate the effects of forest fragmentation and habitat availability on anuran populations. Detections of anurans did not indicate a correlation between the ...
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...
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...
Prehispanic agriculture and climate on the Pacific slope of Guatemala
(University of Missouri--Columbia, 2009)
The relationship between agriculture and social complexity is a complicated one through both time and space; this is no less true in prehispanic Mesoamerica. Human occupation of the Pacific Coast of Gualtemala prior to Spanish contact was affected...
Importance of agritourism for agripreneur goal accomplishment
