Risk and stability of phosphate-immobilized lead in contaminated urban soil and mining sites in the Jasper County Superfund Site
(University of Missouri--Columbia, 2007)
-contaminated urban site, a mill-waste contaminated site, and a mining-waste contaminated site within the Jasper County Superfund Site, Southwestern Missouri. Field plots at the urban site were treated with phosphoric acid at a rate of 10 g kg⁻¹ using surface...
Impacts of municipal wastewater effluent on seed banks, chemistry, and microorganisms of soils excavated from wetland impoundments designated for wildlife
(University of Missouri--Columbia, 2009)
To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set of greenhouse studies...
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
(OC) was the strongest predictor of ICD sorption (p less than 0.0001). The column transport study found peak concentrations of ICD at 5.83, 10.84 and 23.8 pore volumes for crop, grass VBS, and riparian VBS, respectively. HYDRUS-1D results indicated...
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 ...
Methods for high-resolution soil-landscape modeling in midwest upland landscapes
(University of Missouri--Columbia, 2008)
. These methods were tested in the upland landscapes of northern Missouri. Sensors, especially DRS, successfully estimated profile clay and organic carbon. Peak functions were valuable for modeling profile clay content and covariates of clay. Coherent depth...
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 ...
A tall tower wind investigation of northwest Missouri
(University of Missouri--Columbia, 2007)
With energy needs on the rise and our current energy consumption methods polluting the atmosphere, it is the right time to look at alternative forms of energy production. Six Tall Tower wind observation sites were studied in Northwestern Missouri...
Effects of a consortia probiotic inoculant on soil microorganisms and impacts on autoinducers employed in quorum sensing
(University of Missouri--Columbia, 2013)
to degrade autoinducers involved in QS in soil-borne pathogens. The first efficacy was assayed in Central Missouri during growing season of 2012. Soils under two management situations were studied: cultivated soil and restored grassland. Samples from...
On the synoptic and mesoscale organization of mid-latitude, continental convective snow events
(University of Missouri--Columbia, 2008)
An ingredients-based methodology was pursued in order to evaluate the likelihood of thunderstorms occurring in the presence of snowfall (i.e. thundersnow; TSSN). In order to properly distinguish from typical snowstorms ...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
and water quality and given rise to non-point source pollutants. The claypan soil region of Missouri has a high runoff potential that increases the possibility of transport of non-point source pollutants to downstream sites. The Agricultural Policy...
Playa wetland plant and soil response to predicted climate and land use change in the southern Great Plains
(University of Missouri--Columbia, 2019)
"To assess potential risks to playas in a changing climate, weaddressed the following objectives: (1) quantify effects of changing climatic conditions on plant germination and community composition, soil chemistry, greenhouse ...
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 orchards or vines in vineyards...
Polyacrylamide amendment for erosion and runoff control on soils of differing characteristics
(University of Missouri--Columbia, 2009)
The use of anionic polyacrylamide (PAM) as a soil amendment is an emerging conservation practice. However, guidelines have not been developed with considerations of soil properties and topographic characteristics. The ...
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 effects of season...
Use of slow-release N fertilizer to control nitrogen losses due to spatial and climatic differences in soil moisture conditions and drainage in claypan soils
(University of Missouri--Columbia, 2006)
urea in relation to crop N uptake and environmental N loss under four drainage/irrigation treatments in a claypan soil in northeast Missouri. The treatments consisted of: 1) no irrigation or drainage (NIN), 2) no irrigation and drainage (NID), 3...
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 ...
