Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Three essays on Renewable Portfolio Standards
(University of Missouri--Columbia, 2023)
production prices. We extend the framework to incorporate the influence of renewable electricity policy (RPS) and other agricultural policy (CRP). The coefficients of the composite price index are positively related to acreage, while the coefficients...
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)
Distributed watershed hydrologic/water quality (H/WQ) models are ubiquitous tools for watershed management. Despite advancements, there remain impediments for end-users. This study presents a practical framework for use ...
Bulletin : summer session, 1979
(University of Missouri--Columbia., 1979)
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 ...
Identification and characterization of health-promoting benefits and bioactive molecules in black walnuts (Juglans nigra l.) and waste materials from agroforestry systems
(University of Missouri--Columbia, 2020)
selected and cultivated for nut production by the University of Missouri - Center for Agroforestry (Columbia, MO, USA). Additionally, it is likely that the bioactive activities of black walnut are correlated with its bioactive constituents including...
Variability of soil hydraulic properties and estimation of plant-available water on claypan-soil landscapes
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Soil hydraulic properties and plant-available water (PAW) capacity are critical properties in evaluating land management and soil productivity. This study investigated...
An economic analysis of the agricultural development potential for Southern Honduras
(University of Missouri--Columbia, 1975)
for various resources r which would provide guidance for making investment decisions; and (3) to derive policy recommendations for the purpose of agricultural development in Southern Honduras. A survey of 449 randomly selected sample farms, including 686...

A market study of sealed bid competition for Utah public school lunch milk, 1970-1975
(University of Missouri--Columbia, 1981)
This study was designed to determine the influence of various economic factors on sealed bid prices and, accordingly, to serve as a guide for setting these factors to obtain a more competitive price. Traditional concepts on structure, conduct...
Modeling of delayed fluorescence from photosystem II and applications in assessment of drought and chemical stresses
(University of Missouri--Columbia, 2009)
Photosynthesis is not only vital for plant growth and survival but also indicative of plant-environment interactions. This research was designed to analyze photoelectron kinetics and its dependence on environmental factors. ...
