Agroforestry and grass buffers for improving soil hydraulic properties and reducing runoff and sediment losses from grazed pastures
(University of Missouri--Columbia, 2009)Agroforestry buffers, a system of land use in which harvestable trees or shrubs are grown among or around crops or on pastureland, have been proposed for improving water quality in watersheds. The objectives of this study ... -
Analysis of cloud and cloud-to-ground lightning in winter convection
(University of Missouri--Columbia, 2008)The combination of the full suite of cloud-to-ground (CG) and cloud stroke data is used to observe lightning in precipitation events involving winter precipitation. In particular, we observe data for the winter season of ... -
Anthropogenic effects on soil physical, chemical, and biological properties in the Missouri Ozarks
(University of Missouri--Columbia, 2018)The maintenance of healthy forest ecosystems is critical to ensuring the sustainability of forest harvest activities. Forest soil health is a critical component of the knowledge required to manage a forest ecosystem; ... -
Apex and fuzzy model assessment of environmental benefits of agroforestry buffers for claypan soils
(University of Missouri--Columbia, 2013)Contamination of surface waters with pollutants from agricultural land is a major threat to the environment. A field-size watershed study in Northeast Missouri showed that vegetated filter strips containing grass and ... -
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 ... -
Assessing soil carbon and soil quality for sustainable agricultural systems in tropical hillslope soils using spectroscopic methods
(University of Missouri--Columbia, 2017)Soil quality is a concept that integrates physical, chemical, and biological components and processes of soil across landscapes. Identifying and developing appropriate methods to quantify and assess changes in soil quality ... -
Cell identification, verification, and classification using shape analysis techniques
(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The use of object-oriented approaches in both the verification of meteorological variables (especially precipitation) and the short-term forecasting ... -
Characterization of soil organic matter under varying conservation management practices
(University of Missouri--Columbia, 2012)This study examined the effects of three conservation management practices (i.e., no-till, grass vegetative filter strips (VFS) and agroforestry VFS) and four landscape positions (i.e., summit, shoulder, backslope and ... -
Cover crop effects on corn plant water uptake and soil health
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cover crops (CC), close growing crops that provide soil and seeding protection between periods of normal cash crop production or between trees in ... -
Degradation and transport of veterinary antibiotics and estrogens in a vegetated buffer strip system
(University of Missouri--Columbia, 2022)Knowledge of veterinary antibiotic (VA) and estrogenic hormone persistence in soil is critical to understanding environmental risks associated with these potential contaminants. Understanding sorption and transport of the ... -
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 ... -
Forecasting wind speeds at tall tower heights within Missouri
(University of Missouri--Columbia, 2022)Forecasting of wind speeds is necessary for the planning and operations of the wind power generating plants. This research investigates the short term forecasting of wind speeds at tall tower heights for stations within ... -
Grain yield and greenhouse gas emissions from organic and conventional cropping systems on claypan soil landscapes
(University of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] With increasing world populations, farmers must become more efficient at producing food, fiber and fuel while reducing negative environmental impacts. ... -
Greenhouse gas emissions and soil microbial activity for selected land use systems in floodplains
(University of Missouri--Columbia, 2022)According to the Intergovernmental Panel on Climate Change, concentrations of atmospheric greenhouse gases (GHG) have increased since the 1950s caused by human activities which have likely increased the chance of extreme ... -
Historical rainfall analysis and climate implications for agriculture in midwest United States
(University of Missouri--Columbia, 2021)A historical analysis of precipitation using 72 years of data from Midwest stations focuses on the implications of climate change for agricultural interests. The number of precipitation events, consecutive days of ... -
The horizontal redistribution of anomalous vertical heat fluxes at tropical latitudes /
(University of Missouri--Columbia, 2017)A study was conducted to improve quantitative understanding of how anomalous vertical heat fluxes associated with the El Nio-Southern Oscillation (ENSO) are transported poleward to maintain climate equilibrium. State-of-the-art ... -
Identification and characterization of atrazine-degrading phytochemicals in eastern gamagrass
(University of Missouri--Columbia, 2014)Naturally occurring phytochemicals of the 1,4-benzoxazin-3-one (Bx) class exhibit broad chemical reactivity that includes detoxification of chloro-triazine herbicides. Atrazine (6-chloro-N-ethyl-N’-(1-methylethyl)-1,3,5- ... -
