Urea fertilizer placement effects on soil greenhouse gas emissions and corn growth
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Agricultural soils are responsible for a majority of human caused greenhouse gas (GHG) production, such as N₂O and carbon dioxide (CO₂). Nitrous oxide ...
The relationship between Mid-west precipitation rates, teleconnections and blocking in the Eastern and Central Pacific
(University of Missouri--Columbia, 2016)
An integral aspect of accurate precipitation outlooks are timely forecasts of teleconnective phase transitions (i.e., the El Niño Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO)). Through executing ...
Soil physical and hydraulic properties affected by topsoil thickness in switchgrass and row crop management systems /
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Degraded claypan landscapes can be seen as a potential resource for bioenergy production. Therefore, an important decision needs to be made to determine ...
An examination of dual-polarized radar nowcasts and their verification using modern shape analysis techniques
(University of Missouri--Columbia, 2016)
Meteorological forecasting on a very short time scale using radar data has always posed numerous problems since the advent of modern radar technology, including what field to use, how strongly to advect the forecast, and ...
Implications for soil health : assessing crop management systems and cover crops on mid-Ohio glaciated soils
(University of Missouri--Columbia, 2016)
Cropping systems management and the presence or absence of cover crops directly influence many physical, chemical, and biological soil properties. The research hypothesis was the use of cover crops and a no-till crop ...
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
Knowledge of neonicotinoid sorption and transport in soil is crucial to understanding environmental risk associated with the most widely used class of insecticides. To determine mobility and transport of the neonicotinoid ...
Soil quality in organic cropping systems
(University of Missouri--Columbia, 2016)
The objective of this research was to quantify soil quality indicator levels under contrasting organic practices and to provide scientific information that can lead to development of best management practices for organic ...
Enso and PDO climate variability impacts on regional Missouri crop yields
(University of Missouri--Columbia, 2016)
An analysis of crop yields for the state of Missouri was completed to determine if an interannual or multidecadal variability existed as a result of the El Nino Southern Oscillation (ENSO) and the Pacific Decadal Oscillation ...
Evaluation of the non-supercell tornado parameter for the green bay, Wisconsin tornado event of 07 August 2013
(University of Missouri--Columbia, 2016)
The difficulty of detecting and forecasting the development of non-supercell tornadoes (NST) is well documented. The rapid, low level development of NSTs decreases the warning time as they often develop in minutes and can ...
Effects of deep vertical placement of lime on corn and soybean response and soil chemical properties in conservation tillage systems
(University of Missouri--Columbia, 2016)
Soil acidity is one of the most influential factors in limiting crop production around the world. Roughly 30% of the Earth's total land area and as much as 70% of potentially farmable land is affected by soil acidity ...
Discrimination of elevated convection based on low-level radar-derived convergence
(University of Missouri--Columbia, 2016)
Elevated convection has now been widely associated with severe hazards such as large hail and heavy rainfall, however, high winds and tornadoes are not as common (e.g., Grant 1995, Moore et al. 2003, Horgan et al. 2007). ...
An index for anticipating excessive precipitation with elevated thunderstorms
(University of Missouri--Columbia, 2016)
Attempting to predict the location and the initiation of elevated thunderstorms can be very challenging due to the uncertainty in of the mechanisms that release elevated instability (Moore et al., 2003). Excessive Precipitation ...
