References and bias towards agriculture in a middle grade social science textbook
(University of Missouri--Columbia, 2006)
The central purpose of this study was to assess the degree of bias toward agriculture within a middle grade social science textbook. Literary formats used to reference agriculture within the text were also assessed. A content analysis was used...
An essay on the idea and logic of agricultural economics
(University of Missouri--Columbia, 1977)
The idea and logic of agricultural economics is primarily concerned with determining what agricultural economists mean by the "science" of agricultural economics. What is the logic of "scientific discovery" in agricultural economics? What sort of a...
Optimizing crop N use efficiency using polymer-coated urea and other N fertilizer sources across landscapes with claypan soils
(University of Missouri--Columbia, 2008)
Development of improved management practices to increase nitrogen use efficiency (NUE) within agricultural fields is needed to improve crop production and reduce nitrogen (N) loss. Field studies planted to maize were conducted in 2005 and 2006...
Coenzyme Q₁₀ content, composition, texture and physiochemical characteristics of pasta fortified with freeze-dried beef heart
(University of Missouri--Columbia, 2008)
This study evaluated the feasibility of fortifying fresh pasta with beef heart, a beef by-product high in coenzyme Q₁₀. Incorporating freeze-dried beef heart into pasta significantly increased coenzyme Q₁₀ and protein ...
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)
Several agricultural management practices such as terrace construction, cover crops (CC), drainage water recycling (DWR), free drainage (FD), and 4R nitrogen (N) management can influence water quality, soil properties, and crop production...
Biomineralizers from the proterozoic to today : assessing taxonomy and paleoecology through the lens of taphonomy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The onset of metazoan predation is presumed to have triggered an evolutionary arms race of prey defenses, including the advent of biomineralization. Escalating biological...
The assessment of soil enzyme activities in multiple land use in Central Kalimantan, Indonesia
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Peat swamp forest is one of the most important ecosystems in Southeast Asia, particularly in Indonesia. Tropical peat swamp forests contain a high number of valuable timber...
A comparison of soil characteristics in relation to success of a restored prairie
(2013)
The Department of Energy's Weldon Spring Site began as an ordinance site and later became a uranium processing facility. Remediation of hazardous waste resulted in an on-site disposal cell and approximately 150 surrounding ...
Avian nest survival and breeding density in cottonwood plantations and native forest fragments in southeast Missouri
(University of Missouri--Columbia, 2008)
I compared nest survival and breeding density between native bottomland forest and cottonwood (Populus deltoides) plantations over a three-year period for Acadian Flycatcher (Empidonax virescens), Prothonotary Warbler ...
Improvement of co-digesting swine manure and waste kitchen oil
(University of Missouri--Columbia, 2021)
Anaerobic co-digestion of swine manure (SM) and waste kitchen oil (WKO) was conducted to evaluate the effect of substrate loading rates on biogas production efficiency. Biogas yields of M4O2 (4 g-VSSM L-1 d-1 + 2 g-VSWKO L-1 d-1) and M2O1 were 917...
Some factors influencing fruitfulness in apples
(University of Missouri--Columbia, 1918)
"SUMMARY AND CONCLUSIONS: Missouri apple yields tend to rotate in three year cycles, the sizes of the crops produced showing the following order: heavy, light, medium, heavy, etc. A five years' study of the behavior of individual apple fruit spurs...
Quantifying corn emergence using UAV imagery and machine learning
(University of Missouri--Columbia, 2022)
of UAV imagery in the corn emergence assessment at fields of conservation agriculture that are covered with cover crops or residues to improve soil health and sustainability. The overall goal of this research was to develop a fast and accurate method...
Characterization of black walnut (Juglans nigra) cultivars for agroforestry systems
(University of Missouri--Columbia, 2022)
The identification of complementary species combinations will accelerate the expansion of temperate agroforestry. Since the mid-19th century, European timber plantations have taken advantage of the late-leafing habit of ...
Uneven-aged management in the Missouri Ozarks: effects of site conditions, stand density, and prior populations on oak regeneration
(University of Missouri--Columbia, 2022)
While studies have shown the importance of site characteristics and overstory density on the success of white oak regeneration under uneven-aged management, few studies have analyzed the effects of these variables over time in the Missouri Ozarks...
The portfolio problem in agricultural cooperatives: an integrated framework
(University of Missouri--Columbia, 2005)
A portfolio problem within agricultural cooperatives arises as a result of the traditional cooperative's property rights structure. As members' investment is tied to patronage, this traditional structure prevents them from adjusting cooperative...

Soil surface-seal measurement using high-resolution x-ray computed tomography (HRCT)
(University of Missouri--Columbia, 2006)
Rainfall on bare soil breaks soil aggregates, detaching particles, plugging pores and decreasing porosity in the top few mm of soil. This reduces hydraulic conductivity and increases runoff through a process known as surface ...
