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...
Indexes of the influence of weather on corn yields in Missouri
(University of Missouri--Columbia, 1964)
in these measurements of economic phenomena. In agriculture, much of the data does include significant random effects. Weather is one of the primary causes of random variation in agricultural production and has a significant effect on yield data. In fact, this random...
Minimum milk requirement for calf raising
(University of Missouri--Columbia, 1919)
The dairyman is keenly interested in knowing how he can raise his calves in an economical and successful manner. This thesis reports the results of several experiments in early weaning and minimum use of milk for calf rearing, which constitute part...
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...
Insight into the roles of prescribed fire and hardwood competition in the survival and growth of shortleaf pine throughout its early life
(University of Missouri--Columbia, 2023)
pine is competition from hardwoods. In Missouri specifically, many sites formerly occupied by shortleaf pine are now dominated by oak species with established and highly competitive advanced regeneration. Prescribed fire is a tool often used...
Development of implementation methods of water quality trading policy : using the Hydrological simulation program-Fortran (HSPF)
(University of Missouri--Columbia, 2010)
-fortran (HSPF) was used to estimate the hydrology and sediment loading throughout the Brush Creek, MO watershed for future land use development scenarios between upstream and downstream locations. Brush Creek does not have a proper monitoring station...
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 ...
To study the effect of pregnancy and of nursing on the maintenance requirement of mares

Storage facilities of Missouri country elevators
(University of Missouri., 1958)
"The objectives are to determine adequacy of present storage facilities by Crop Reporting Districts and to provide information for decisions relative to location, capacity, type, remodeling, and rebuilding of country ...
Investigation of transportation innovations for food delivery and truck platoons
(University of Missouri--Columbia, 2022)
discusses the novel issue of driver behavior interacting with truck platoons in work zones. This research investigates the effects of education, platoon signage, and the number of platooned trucks using a federated simulator study. The study found...
The effect of calcium carbonate of certain soil constituents and on plant growth
(University of Missouri--Columbia, 1915)
of Problem": It is the purpose of this investigation to secure data on the effects of adding calcium carbonate in the form of ground limestone to types of soils of common occurrence in the state of Missouri. These effects were studied in crop yields, in per...
Impacts of municipal wastewater effluent on seed banks, chemistry, and microorganisms of soils excavated from wetland impoundments designated for wildlife
(University of Missouri--Columbia, 2009)
To evaluate the effects of municipal wastewater effluent (WWE) and Missouri River water (MOR) as irrigation sources on soil chemistry, seed banks, and microorganisms, a field study was conducted in conjunction with a set of greenhouse studies...
The potential of producing bioenergy crops on conservation reserve program land in Missouri, Iowa, Nebraska, and Kansas (MINK Region) to mitigate carbon dioxide emissions : an integrated economics and biological modeling approach
(University of Missouri--Columbia, 2010)
Concerns about global warming and climate change have generated increasing interest in development of bioenergy crops as a potential source of low-carbon energy. The goal of this research was to quantify environmental and economic effects of using...
Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)
compared fall herbicide applications to early spring applications. Therefore, field experiments were conducted in both no-till corn and soybean fields from 2004 through 2006 in central, northwest, and northeast Missouri. Herbicide applications were made...
