Pollution Of Surface Irrigation Waters By Plant Pathogenic Organisms, James R. Steadman, C. R. Maier, H. F. Schwartz, E. D. Kerr
Pollution Of Surface Irrigation Waters By Plant Pathogenic Organisms, James R. Steadman, C. R. Maier, H. F. Schwartz, E. D. Kerr
Department of Plant Pathology: Faculty Publications
Systematic sampling of waterways and irrigation runoff from agricultural lands in the North Platte Project of Nebraska in July and August of 1972–1974 demonstrated that phytopathogenic organisms were disseminated. The organisms monitored included the bean common blight bacterium Xanthomonas phaseoli, the bean white mold fungus Whetzelinia sclerotiorum and various nematodes. Although many types of nematodes often were recovered from irrigation water, Heterodera sp. cysts which cause significant disease problems in the valley were found infrequently. Patterns of movement of the bacterial and fungal organisms were correlated with previous or current season infection of bean plants. The short-term survival of X. …

Scope Of Work, Environmental Impact Statement For The Dickey-Lincoln School Lakes Project, New England Division, United States Army Engineer Division, United States Army Corps Of Engineers
Dickey-Lincoln School Lakes Project
Revised draft combines data previously published in two separate impact statements prepared by the corps relating to the dams, reservoirs and power plants and by the U. S. Department of Energy for transmission facilities to link the St. John River development to the New England power grid. The latter agency is responsible for the marketing and distribution of power generated at federally-financed installations.

Hydroelectric Power Potential At Corps Of Engineers Projects : A Report, Ralph L. Trisko, United States. Army., Institiute For Water Resources
Dickey-Lincoln School Lakes Project
This report completes phase one of the study. It is intended to fill the need, recognized at the outset, for a broad framework within which subsequent more detailed study at the project level might take place. It is an overview of physical hydropower potential in the context of energy and water resources and demands, energy economics, and federal policy, organization, and practices pertaining to hydropower development and marketing.
Growing Sunflowers In South-Western Australia, M L. Poole
Growing Sunflowers In South-Western Australia, M L. Poole
Journal of the Department of Agriculture, Western Australia, Series 4
The oil produced from sunflowers falls into the "polyunsaturated" group and usually commands a premium price on world markets.
Some Western Australian farmers seeking to diversify their cropping programmes in the face of marketing difficulties for many agricultural products are trying sunflowers, although commercial production has not yet been achieved.
This article sets out some basic information for farmers wishing to try sunflowers.
Integrated Numerical Simulation Of Drip Irrigation With Subsurface Drainage, James Ray Hoover
Integrated Numerical Simulation Of Drip Irrigation With Subsurface Drainage, James Ray Hoover
Electronic Theses and Dissertations
A numerical method and model were developed to simulate soil moisture during steady-state and transient flow toward a tile drain. Intermittent application of water by drip irrigation and rainfall were simulated by use of finite difference approximation equations. No known analytical solution for these flow situations exists because of the complex mathematics describing unsaturated flow in the soil. The computer model is based on the electrical resistance network analog. The explicit finite difference equations were solved by the successive over-relaxation method for steady-state flow and by iteration for transient soil moisture flow. The computer program for the model consists of …
