Winter rations for dairy heifers
(University of Missouri--Columbia, 1918)
"Comparatively little experimental data are as yet available concerning these problems of raising heifers. The purpose of the author in conducting the experiments reported in this thesis was to add to the data now available regarding the wintering...
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...
Agroforestry and cover crops for improving surface water and groundwater quality
(University of Missouri--Columbia, 2023)
Unsustainable agricultural practices and the rapid expansion of agricultural lands to satisfy the food demand of the growing world population have caused significant sediment, and nutrient losses from agricultural fields, harming the environment...

(University of Missouri--Columbia, 2008)
and 2006. A quantitative content analysis of 456 stories, a qualitative framing analysis on a subset of that coverage, and interviews with a science or medical reporter at each newspaper provided converging lines of inquiry. This study finds that one...
Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
