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 Act. This study examined...
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...
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 ...
Groundwater vulnerability to agrochemicals: a GIS-based DRASTIC model analysis of Carroll, Chariton, and Saline counties, Missouri USA
(University of Missouri--Columbia, 2006)
This investigation presents an analysis of groundwater vulnerability in three mid-Missouri counties that represent an agricultural production region that is physiographically and hydrogeologically complex. The goals of this study are to (1) provide...
The potential of producing bioenergy crops on conservation reserve program land in Missouri, Iowa, Nebraska, and Kansas (MINK Region) to mitigate carbon dioxide emissions : an integrated economics and biological modeling approach
(University of Missouri--Columbia, 2010)
policymakers develop sustainable and balance of energy-agriculture-environmental policies....
Three essays on the competitiveness of the US corn seed industry
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation provides an analysis of various aspects of the competitivity of the US corn seed industry. In the first essay I develop a price depend model of seed demand...

Effect of irrigation on fertilizer nitrogen requirement, economic returns, and water availability in a corn-soybean rotation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In regions of the US and the world where precipitation does not consistently meet crop water needs, there is extensive research documenting the value of irrigation to increased...
Application of the systems approach : an information and decision model for the hog enterprise

Neonatal beef calf morbidity and mortality in Missouri
(University of Missouri--Columbia, 2022)
Neonatal morbidity and mortality are major causes of economic loss for US beef cattle producers. The Missouri cattle industry represents 19 percent of the total agriculture sales in the state and is valued at 1.6 billion dollars. It is estimated...
Dry milling characteristics and polyphenolic contents of adapted colored corn varieties and polyphenol extraction by combining deep eutectic solvents and ultrasound
(University of Missouri--Columbia, 2023)
breeding program at the University of Missouri and their milling coproducts were ascertained and compared with a commercial purple corn. With mean large grits yield of 22.98 percent (db), colored varieties had a dominant softer endosperm composition...
Automated and non-contact human finger range of motion measurement system

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Nitrogen is a macronutrient that is critical for plant growth and development because it provides the building blocks of nucleic acids, proteins, chlorophyll, and energy...
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...
Evaluation of modified montmorillonites in poultry diets
(University of Missouri--Columbia, 2007)
The present work was conducted to determine if modification of MONTs with Cu and Zn would enhance the protection of broiler chicks against the adverse effects of AF, and to determine if the modified MONTs would be bioavailable ...
