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 who exhibited a systematic...
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...
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...
Influence of characters of ear and kernel upon the germination of maize
(University of Missouri--Columbia, 1912)
of the ear and kernel which have a marked influence upon the yield. This is so universal that we have score cards which set forth the ideal type of ear and give certain values to the different characters. In general, the score cards are alike and all agree...
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 ...
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...
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 ...
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 ...
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 ...
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...
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...
