Assessing impacts and targeting of agricultural conservation practices
(University of Missouri--Columbia, 2010)
The U.S. Department of Agriculture initiated the Conservation Effects Assessment Project in 2003 to quantify water quality and wildlife benefits of conservation programs funded by the 2002 Farm Security and Rural Investment ...
Impacts of soil management practices on soil fertility in potato-based cropping systems in the Bolivian Andean highlands
(University of Missouri--Columbia, 2010)
Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in ...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
Water and soil are two key elements for life on this planet, and improving and preserving their quality are of prime importance. Various human actions including use of intensive chemicals in agriculture have accelerated ...
Enhanced rhizodegradation of munitions explosives and degradates by selected native grass species
(University of Missouri--Columbia, 2010)
TNT (2,4,6-trinitrotoluene) and RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) are the two most widespread explosives in the world. The manufacture, use and disposal of explosives can result in environmental contamination, ...
Climatology of atmospheric blocking 1978-2008 : global and hemispheric breakdown, as well as impacts of temperature, and global climate cycles
(University of Missouri--Columbia, 2010)
An examination of atmospheric blocking from the years 1978-2008 was conducted to explore the impacts of temperature and climate cycles on blocking intensity, blocking duration, and total blocking events on an annual basis. ...
Analysis of forecast performance for hit, miss, and false alarm thundersnow events during ROCS
(University of Missouri--Columbia, 2010)
Thundersnow (TSSN) is a mesoscale event that is typically associated with large amounts of precipitation and both in-cloud and cloud-to-ground lightning. Starting in 2003, the Research on Convective Snows (ROCS) group began ...
Forest harvest effects on soil chemical properties and nutrient concentrations in Ozark Highland soils
(University of Missouri--Columbia, 2010)
Mixed hardwood systems of the Missouri Ozark Forest Ecosystem Project are harvested using clearcutting (CC) and single-tree selection (STS) regeneration methods. This work indicates possible effects of regeneration method ...
Streambank erosion and risk assessment of contaminant transport in Missouri watersheds
(University of Missouri--Columbia, 2010)
Sedimentation and herbicide are significant water quality concerns in claypan watersheds. Two separate watershed-scale studies were conducted in the Central Claypan Region of northeastern Missouri. One project investigated ...
The use of geomorphological and pedological soil characteristics to assess planar borrowing at a Mandan Indian village, North Dakota
(University of Missouri--Columbia, 2011)
The Double Ditch State Historic Site is situated in a loess landscape immediately east of the Missouri River near Bismarck, North Dakota. The site was occupied from ca AD 1450 to 1785 by Mandan Indians, Plains Villagers ...
Soil microbial contribution to greenhouse gas efflux from a secondary forest in central Missouri
(University of Missouri--Columbia, 2011)
Greenhouse gas emissions (GHG) vary with the interactions among physical, chemical, and biological characteristics of soil and microclimate. Soil microorganisms are involved in almost all soil processes, and are also ...
Regional and geomorphic influence on soil genesis and oak ecosystems in the Chariton River Hills of Missouri
(University of Missouri--Columbia, 2011)
Little is known about soil, geomorphic, and vegetation relationships in the moderately-dissected glaciated forests of the Chariton River Hills Ecological Subsection (CRHES). To gain a better understanding of these relationships ...
The interannual and interdecadal variability of the Borneo vortex during boreal winter monsoon
(University of Missouri--Columbia, 2012)
The boreal winter monsoon over the Malaysian region has long been associated with heavy rainfall activity and flood disaster. One of the main features that characterized this monsoon is the presence of the Borneo vortices. ...
The verification of weather forecasts compared to numerical model guidance, climatology, human forecasts and seasonal variations
(University of Missouri--Columbia, 2011)
The accuracy of weather forecasts has been a topic of discussion for many years, and a simple but useful method for showing forecast accuracy has been an issue for meteorologists over time. My study on the comparison of ...
Effects of selected surfactants on nutrient uptake and soil microbial community
(University of Missouri--Columbia, 2011)
Surfactants with solvent and wetting abilities are used in the formulation of herbicides to enhance spraying capabilities. These chemicals eventually enter into the soil and may disrupt different chemical, physical and ...
Land use effects on greenhouse gas production in lower Missouri River floodplain soils
(University of Missouri--Columbia, 2012)
Soil-based greenhouse gases (GHG) are produced primarily through plant and microbial processes and are affected by soil properties. The lower Missouri River Floodplain (MRF) region encompasses different land use systems ...
Sorption and transport of veterinary antibiotics in agroforestry buffer, grass buffer, and cropland soils
(University of Missouri--Columbia, 2011)
Understanding sorption and transport of veterinary antibiotics (VAs) is important for assessing the risk of VAs reaching water resources. Vegetative buffer strips (VBS) may be a useful tool for mitigating veterinary ...
The verification of weather forecasts, numerical modeling, climatology, and variations in enso cycles in forecast accuracy
(University of Missouri--Columbia, 2011)
Weather forecasting has been a difficult problem for meteorologist for more than one hundred years. In the early days, our understanding of atmospheric processes was limited by our incomplete understanding of the governing ...
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 ...
Nitrogen fertilizer management of temporarily waterlogged soils to improve corn production and reduce environmental nitrogen loss
(University of Missouri--Columbia, 2014)
