by education consultants from the Missouri Department of Conservation that corresponded to the visited sites. Qualitative data was obtained from each of the data sources in order to determine 1) what features had been funded, 2) level of implementation, and 3...
Establishment of native plant species for livestock forage in silvopasture systems
(University of Missouri--Columbia, 2022)
affect establishment of native plant species. The experiment was a Randomized Complete Block Design replicated in 2020 and 2021. Treatment establishment (3 treatments, 3 replications each) began each fall preceding the growing season by no-till drilling...
Forging a national diet : beef and the political economy of plenty in postwar America
(University of Missouri--Columbia, 2018)

Ferns as a forest farming crop: effects of light levels on growth and frond quality of selected speicies with potential in Missouri
(University of Missouri--Columbia, 2006)
In Missouri 11.3 million acres of commercial forests are privately owned. The vast majority is under very little - if any - management. Agroforestry, specifically forest farming, has the potential to provide producers an opportunity to put...
The role of genetic and phenotypic diversity in maize and its effects on aflatoxin accumulation by the fungus Aspergillus flavus
(University of Missouri--Columbia, 2008)
Accumulation of the potent carcinogen, aflatoxin, in maize poses a significant health risk to humans and animals. Most commercially grown maize lines are susceptible to infection by the fungus that synthesizes aflatoxin, ...
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...
A multi-configuration evaluation of the soil and water assessment tool (SWAT) in a mixed land use watershed in the central U.S.A.
(University of Missouri--Columbia, 2011)
. Watershed and soil resolution had negligible impact; climate input had considerable impact. Single climate station input is best used for applications requiring monthly predictions; distributed climate station input is needed for daily predictions. SWAT...
Determining the efficacy of a biosensor to detect calpastatin, a meat tenderness indicator
(University of Missouri--Columbia, 2007)
An instrumental tenderness detection system used at the time of grading to sort beef carcasses on their predicted tenderness would be valuable for the beef industry. A biosensor to accurately predict calpastatin, the ...
Forecasting wind speeds at tall tower heights within Missouri
(University of Missouri--Columbia, 2022)
Forecasting of wind speeds is necessary for the planning and operations of the wind power generating plants. This research investigates the short term forecasting of wind speeds at tall tower heights for stations within Missouri: Columbia, Neosho...
The family farm in the post-World War II era : industrialization, the cold war and political symbol

The growth of the dairy industry has been an important factor in the agricultural development of the United States. Missouri has shared in this development. The sale of dairy products has contributed nine to thirteen percent of the total income from...
Development of high protein soybean experimental lines with enhanced sulfur amino acid content
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is one of the most important field crops grown in the United States. Commercial soybeans contain about 36 - 40 [percent] protein and 18 - 20 [percent] oil, by dry weight...
Evaluation of the bonus fishery created by the low-density stocking of Striped Bass (Morone saxatilis) in Bull Shoals Lake
(University of Missouri--Columbia, 2023)
Bull Shoals Lake is a large impoundment of the White River system in Missouri- Arkansas. Striped Bass (Morone saxatilis; STB) have been experimentally stocked into Bull Shoals since 2013 to create a low-density trophy fishery. We addressed...
