Composition of soil as affected by different cropping systems
(University of Missouri--Columbia, 1913)
Among the experiments in soil fertility which are being carried out by the University of Missouri College of Agriculture is a series of plot experiments which have been in progress since 1889. There are thirty-nine plots in the field and each has...
Restoration treatments and regeneration dynamics in East Texas mixed wood forests
(University of Missouri--Columbia, 2023)
Extensive harvesting, fire exclusion, and plantation forestry altered composition and structure, and thus function and habitat values of east Texas Pineywoods uplands. Upland restoration efforts are made difficult by the ...
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...
Investigation upon the nitrogen, phosphorus, sulfur, and ash content of three beef animals, with special study upon the forms of sulfur
(University of Missouri--Columbia, 1917)
This thesis explores the chemical composition of beef cattle, with special attention given to nitrogen, phosphorus, sulfur, and ash content. A review of previous research is provided as well as a description of an experiment carried out...
Three essays on biofuel policies and aggregate supply curve
(University of Missouri--Columbia, 2022)
The first essay investigates the impacts of Brazil's new biofuel policy, namely RenovaBio. RenovaBio aims to reduce greenhouse gas (GHG) emissions in the transportation sector through expansion of biofuels by requiring ...
Predator-prey interactions involving the soybean aphid (Hemiptera: Aphididae) in Missouri
(University of Missouri--Columbia, 2007)
The recently introduced soybean aphid, Aphis glycines Matsumura, is found in all soybean growing areas within Missouri. Despite soybean aphid's widespread distribution, it has reached economic threshold in few soybean fields in Missouri. We...
Analysis of twenty-five years of heavy rainfall events in the Texas Hill Country
(University of Missouri--Columbia, 2008)
climate stations in the region; the period examined for this study was 1982-2006. Days with measurable precipitation were treated as a gamma distribution in order to determine the top 2%, 1%, and 0.5% to define events as unusual, rare, and extreme...
Urban Riparian Areas: Ecological And Streamside-Ordinance Assessments
(University of Missouri--Kansas City, 2018)
Streamside protection ordinances have been established in many urbanizing areas;
however, there has been a paucity of assessments of the effectiveness of such ordinances. A
quantitative assessment of the ecological ...
Effects of dormant season soil flooding and soil temperature on pin oak (Quercus palustris) seedlings
(University of Missouri--Columbia, 2022)
. During soil flooding, root mass was significantly less in flooded seedlings than those that were not flooded. However, following drainage this difference was no longer present. By the end of the experiment, seedlings that received flooding exhibited...
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 ...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
. This dissertation includes results from four studies conducted at the MU Greenley Research Center, Grace Greeley farm, and Ross Jones farm. Long-term, no-till research evaluated the influence of a wheat (Triticum aestivum L.), radish (Raphanus raphanistrum subsp...
The demography of Atlantic brant (Branta bernicla hrota)
(University of Missouri--Columbia, 2022)
for greatest understanding of population level processes and to inform prioritization of conservation efforts for Atlantic brant. Future brant research should focus on nutrient dynamics of James Bay staging areas, identifying core breeding areas and quantifying...
