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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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. ...
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. ...
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 ...
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 ...
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. ...
Enhanced efficiency phosphorus application for corn
(University of Missouri--Columbia, 2012)
Farmers are interested in the use of enhanced efficiency phosphorus (P) fertilizer applications or treatments. The objectives of this research are (1) to determine the effects of tillage/fertilizer placement [no-till ...
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 ...
A Study of the effect of liming an acid soil on the growth of certain legumes and non-legumes
(University of Missouri--Columbia, 1914)
A number of investigators have found that applications of lime to an acid soil have in many cases resulted in a depression of crop yields. This effect has been observed especially in connection with pot cultures where ...
Effects of veterinary antibiotics on atrazine degradation in soil
(University of Missouri--Columbia, 2014)
The release of veterinary antibiotics (VAs) in the environment is concerning because VAs have been linked to the development of antimicrobial resistant bacteria and may influence nutrient cycling and agrochemical degradation. ...
Soil phosphorus pools and harvest effects on soil solution chemistry in the Missouri Ozark Highlands
(University of Missouri--Columbia, 2013)
Forests ecosystems are governed by complex and dynamic nutrient cycles where soil is a major provider of nutrients essential for plant growth. Disturbances occurring in forested ecosystems (timber harvest, fire, and disease ...
