This study examined how fire risk, a combination of fuels conditions and fire probabilities, varied across a large portion of Missouri, Illinois, and Indiana. Case studies were conducted to evaluate the fuel loading variability in Missouri Ozark...
The effects of various planes of nutrition upon the cost of maintenance, reproduction, and development of beef cows
(University of Missouri--Columbia, 1916)
The frequency with which valuable animals reproduce themselves has always been a factor of economic importance in the pure bred cattle business. Great economic changes during the last few years have made this an important ...
Use of green manures & cover crops for the south
(University of Missouri--Columbia, 1907)
The problem of restoring the fertility to the worn soils and of maintaining that of the new or fresh soils is perhaps the most serious one with which the farmers of the cotton states are confronted. It is indeed unfortunate ...
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
sorption and column leaching experiments were performed using soils collected from cropland (crop), grass vegetative buffer strips (VBS), and riparian VBS. Single-point, solid-to-solution partition coefficients (Kd) were determined by reacting soil...
Effects of prescribed burning in Missouri Ozark upland forests
(University of Missouri--Columbia, 2007)
Prescribed fire is used in Missouri to achieve various silvicultural goals, but the use of burning in upland Ozark forests raises many questions that research has yet to answer. The purpose of this study is to examine the effects of prescribed...

(University of Missouri-Kansas City, 2012-06-14)
The Komadugu-Yobe River located in northeastern Nigeria is an important tributary of Lake Chad. Since the 1970s, the Komadugu-Yobe basin has experienced significant changes in population density and land use/land cover. ...
Establishing pin oak reproduction in bottomland forests in southeastern Missouri
(University of Missouri--Columbia, 2010)
In pin oak (Quercus palustris Muenchh.) bottomland forests in southeast Missouri, we revisited clearcuts, shelterwood harvests, and controls within the Mingo Basin. Seventeen years later, we found significant changes, in both the change in basal...
Horse flesh and its digestibility
(University of Missouri--Columbia, 1919)
The use of horse flesh as a human food is a custom as old as that of using the flesh of any other food producing animal. Proof of its use by the cave men has been unearthed in Northern Europe by archaeologists. Judging ...
