Effects Of Land Disposal Of Pulp Mill Effluents On Plant Nutrient Uptake And Element Balance, Joseph B. Schwarzback
Effects Of Land Disposal Of Pulp Mill Effluents On Plant Nutrient Uptake And Element Balance, Joseph B. Schwarzback
Electronic Theses and Dissertations
An analysis of the soil and plant tissues was undertaken to ascertain the effect that land irrigation with pulp mill effluent has on nutrient uptake and element balance of tree seedlings. Results show that the effluent significantly increased the sodium content of both soil and tissue; however, these levels fell far below the level necessary to become detrimental to plant life, soil chemistry and soil structure. There was evidence that the increase of elements from the effluent provided positive effects in growth and plant health. There was no evidence of sodium toxicity or calcium starvation. Evidence clearly points out the …

Effects Of Fungus-Fermented Soybeans On Broiler Growth And Life Cycle Performance Of Coturnix Quail, Cheong Choo Chah
Electronic Theses and Dissertations
Despite the extensive data that have accumulated on the detrimental effect of molds on the growth of farm animals, very little is known as to the beneficial role of fungi in animal feed. Recent studies at South Dakota State University research laboratories revealed, however, that only 164 of 392 strains of Aspergilli were found to be toxic. When the cultures were grown on sterile soybeans or wheat, some of the tested cultures exerted positive effects on growth of chicks and mice. Hence, the investigations reported herein were initiated to obtain further information on those cultures beneficial to chick performance and …
American Labor Unions: Structure, Conduct, Performance, Lyle Adrian Johnson
American Labor Unions: Structure, Conduct, Performance, Lyle Adrian Johnson
Electronic Theses and Dissertations
Given some specific assumptions, theories have provided specific conclusion concerning unions. This type of theoretical framework, however, provides for a ''narrow" discussion of union activities. General textbooks written about labor unions supply an opposite approach by providing much material dealing with union relationships. A more comprehensive approach, however, may be developed through an analysis of labor unions with industrial organization theories. This type of analysis allows one to see both the forest and the trees. The specific objectives of this research paper are to study: 1. union organizations and their operations 2. antitrust policy toward union structure 3. strike costs …

Parasites Of Salmonid Fishes From Southcentral Alaska, James Carl Riis
Parasites Of Salmonid Fishes From Southcentral Alaska, James Carl Riis
Electronic Theses and Dissertations
The importance of fish parasites is directly related to the value of the fish they affect. Alaskan salmonids are extremely important and are constantly increasing in value to the United States. Other countries, such as Japan and Russia, are also finding Alaskan salmonids important as a foodstuff. If human populations continue growing at present rates, in only a few years there could be twice as many people eating fish. As a recreational asset in Alaska, salmonids rank at or near the top, both for sportfishing and as a natural attraction. It is thus important from an economic point of view …
Volatility, Drift And Phytotoxicity Of Dicamba To Corn When Applied With Additives, Bart A. Brinkman
Volatility, Drift And Phytotoxicity Of Dicamba To Corn When Applied With Additives, Bart A. Brinkman
Electronic Theses and Dissertations
Herbicides have become an important asset to the farmer since the discovery of 2,4-D as a useful weed killer. Although herbicides are a relatively new and useful tool, various hazards are associated with their use. Drift and volatility are of primary concern. Air pollution is recognized as an environmental detriment to both plants and animals. The prevention of herbicide drift and volatility is necessary to maintain an environment suitable for many plant habitats. Dicamba (3,6-dichloro-o-anisic acid) is used to control broadleaf weeds in corn, small grains, lawns, and rangelands. Sometimes nontarget areas adjacent to crops are affected seriously because of …

Sulfur Supplementation With Soybean Meal Or Urea For Feedlot Lambs, Joseph Cletus Ebert
Sulfur Supplementation With Soybean Meal Or Urea For Feedlot Lambs, Joseph Cletus Ebert
Electronic Theses and Dissertations
One of the urgent tasks facing agricultural scientists throughout the world is that of supplying sufficient food of adequate quality to the ever-increasing human population. The problem is not only that of supplying calories but also providing adequate quantity and quality of protein. Ruminant animals have the ability to convert much plant energy, not utilizable or having low availability for man, and nonprotein nitrogen products into body tissues. Ruminant animals, therefore, can have a very important role in providing food for the human population. The most widely used nonprotein nitrogen compounds urea. The process of building amino acids into body …
