Composition of soil as affected by different cropping systems
(University of Missouri--Columbia, 1913)
Among the experiments in soil fertility which are being carried out by the University of Missouri College of Agriculture is a series of plot experiments which have been in progress since 1889. There are thirty-nine plots in the field and each has...
Three essays on phosphorus runoff and water quality
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Water pollution caused by nutrients, and the resulting eutrophication, have increased over time. This water pollution is increasingly caused by non-point source pollution, both...
The effect of age and condition on the mineral composition of the ash of the bovine
(University of Missouri--Columbia, 1916)
and in most cases incomplete. Furthermore, a great deal of the data as presented by various investigators cannot be compared because of lack of uniformity in reporting results as well as in the selection of samples for analysis. Forbes in his bulletin on "The...
Climate and land use effects on hydrologic processes and water allocation in a primarily rain-fed, agricultural watershed
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] There is a need to raise our understanding of the impact of climate variability and change on hydrologic processes at the watershed scale. This is important, particularly...
Stand structure development effects on wood quality of Melina (Gmelina arborea roxb.)
(University of Missouri--Columbia, 2009)
A stem analysis was perform to examines the effects of thinning treatments on Melina (Gmelina arborea) wood quality and tree architecture in the North Coast of Colombia. 27 plots under forest management regimes and age ...
Restoration treatments and regeneration dynamics in East Texas mixed wood forests
(University of Missouri--Columbia, 2023)
Extensive harvesting, fire exclusion, and plantation forestry altered composition and structure, and thus function and habitat values of east Texas Pineywoods uplands. Upland restoration efforts are made difficult by the ...
A Python-based GIS simulation of a water balance for wetland decision-making
(University of Missouri--Columbia, 2021)
wetland site to determine the potential existence of the excess water component. The study area is a location within Pershing State Park within Linn County, Missouri. Three goals have been set in this research in order to achieve the ultimate goal...
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...
Estimation of demand parameters : an empirical analysis of consumer behavior in the United States
(University of Missouri--Columbia, 1971)
Demand analysis is a key element of economics. It has the attractive feature of being important in theory as well as in application. Its purpose is to explain consumer behavior in the market place, i.e., demand analysis ...
