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 ...
An investigation into the contribution of the low-level jet (LLJ) to the available wind resource in Missouri
(University of Missouri--Columbia, 2009)
This work uses data (1 September 2006-31 August 2007) from a network of tall-towers to investigate the impact of the nocturnal low-level jet (LLJ) on near-surface winds in Missouri. Of particular interest is the contribution ...
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, ...
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 ...
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. ...
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 ...
The amount of edible meat in the various cuts from animals of known life histories
(University of Missouri--Columbia, 1909)
This series of experiments was undertaken with the thought of studying the composition of the different cuts of meat from the housekeeper's standpoint, to determine what cut of meat will furnish the most edible meat for a ...
Control of the humus supply of certain important Missouri soils
(University of Missouri--Columbia, 1908)
The soils of Missouri, with very few exceptions, are deficient in humus, and the continuous cropping (to corn especially) which is practiced in many parts of the state is rapidly depleting what humus there is in the soil. ...
Experiment to determine the relation existing between drainage water and the soil, and the relation existing between drainage water and rainfall
(University of Missouri--Columbia, 1907)
The time chosen for conducting this experiment was the year of 1906. The drainage water taken was that of Richland creek which drains a territory of 84,954 acres. This valley is located in the southwestern part of Madison ...
Soil quality as affected by agroforestry and grass buffers in grazed pasture and row crop systems
(University of Missouri--Columbia, 2011)
Establishment of agroforestry and grass buffers within agroecosystems is believed to improve soil quality. Soil enzyme activities and water stable aggregates have been identified as sensitive soil quality indicators to ...
Kinetic energy flux associated wiht natural and simulated rainfall events and instrumentation used in the evaluation
(University of Missouri--Columbia, 2011)
There have been many studies that focus on the evaluation of the raindrop-size distribution and the parameters that are based upon this distribution, ranging from radar reflectivity to kinetic energy flux at the surface. ...
Relation of lime and magnesium to plant growth in Missouri soils
(University of Missouri--Columbia, 1906)
The relation of lime and magnesium to each other in plant growth is a problem over which the Agronomist and Plant Physiologist have stumbled for some time, and before its solution is finally reached, will likely involve ...
Some factors influencing the germination of corn : a thesis
(University of Missouri--Columbia, 1908)
One line of agricultural investigation that has been much neglected is that of determining what factors may influence the germination of corn. There has been in fact no direct work done along this line that is available ...
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 ...
Use of green manures & cover crops for the south
(University of Missouri--Columbia, 1907)
The problem of restoring the fertility to the worn soils and of maintaining that of the new or fresh soils is perhaps the most serious one with which the farmers of the cotton states are confronted. It is indeed unfortunate ...
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 metabolism and localization of glycerol by bovine spermatozoa
(University of Missouri--Columbia, 1958)
Since the discovery that glycerol, a trihydroxy alcohol, would provide protection for spermatozoa during the freezing and thawing process, many questions have arisen concerning its metabolism and mode of action. Most of ...
The effect of liming an acid soil on the growth of certain legumes
(University of Missouri--Columbia, 1914)
The experimental work for this thesis was planned to secure information as to the effect of limestone applied to an acid soil (1) on the growth of legumes, (2) on the activities of tuberclue bacteria, and (3) on the amount ...
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 ...
