Soil Conservation means, basically sound land management. With good management the Ste's resources of productive land can be bot only maintained but actually improved. It is a question of deciding the best use for each soil type and situation. Profitable Production must be kept up in changing economic conditions without destroying land assets in the process.

A New Tribe Of Saber-Toothed Cats (Barbourofelini) From The Pliocene Of North America, C. Bertrand Schultz, Marian R. Schultz, Larry D. Martin

Bulletin of the University of Nebraska State Museum (1924–2023)

A new genus of Pliocene Saber-toothed felid, Barbourofelis, is proposed and two new species B. fricki and B. morrisi are described. These two forms and other described material represent an unusual lineage of felids with long sabers, shortened crania, and massive postorbital bars. The tribal name Barbourofelini is proposed for this lineage which is presently known in North America from deposits ranging in age from Clarendonian through Kimballian. The Barbourofelini apparently migrated from Eurasia to North America in the Late Miocene or Early Pliocene. Sansanosmilus of the French Vindobonian appears to represent the ancestral stock of these cats. The …

Part I - Controlling The Soil Moisture Environment Of Transpiring Plants, Part Ii - Prediction Of Leaf Temperature Under Natural Atmospheric Conditions, Charles T. Haan, Billy J. Barfield, Robert Edling

KWRRI Research Reports

Part I

A technique for controlling the soil moisture potential in the root zone of transpiring plants was developed. The method uses the principles of unsaturated flow through a porous media to develop the desired moisture potential. In the case of non-steady state transpiration, the maximum possible fluctuation in the soil moisture potential can be determined by the techniques presented.

Part II

Two implicit leaf temperature prediction equations were derived from the energy balance approach. The equations define sensible and latent heat transfer from a plant population as a two step process:

1. Transfer between the plant leaf and the canopy …

Annual Summary Of Experimental Results 1970-71 - Evaluation Of Pasture Species, G H. Walton

Experimental Summaries - Plant Research

During 1970 interest in the small ungrazed Legume Species Trials was reduced to ten trials located in the more troublesome areas. Five of the trials are on the sandy soils of the Midland Plain three trials are in Merredin-Southern·cross region, one is on deep sand at Tincurrin and the other is at Pindar. All thesites are sandy soils on which the sub clover strains appear to perform the best. The newer trials are investigating the value of sub clover cultivars such as Northam A,Mt Helena A, Shenton Park A, and Daglish. These trials will be the subject of a special …

Soil Microbiology, D E. Chatel

Experimental Summaries - Plant Research

SUBTERRANEAN CLOVER INOCULATION EXPERIMENTS Badgingarra and Newdegate Comparisons between Rhizobium trifolii strain WU290 and possible replacement strains were continued. The work was conducted for the following reasons 1. The need for information on "back-up" strains particularly since the inoculant manufacturers had experienced difficulty in producing high-count peat cultures of WU290. 2. Strain CC2480a had proved very satisfactory in the Eastern States. Although it did not show up to advantage under our conditions in 1968,further testing was indicated. 3. The need for information on inoculation needs on old land.

Opset Program For Computerized Selection Of Watershed Parameter Values For The Stanford Watershed Model, Earnest Yuan-Shang Liou, L. Douglas James

KWRRI Research Reports

The advent of high-speed electronic computer made it possible to model complex hydrologic processes by mathematical expressions and thereby simulate streamflows from climatological data. The most widely used program is the Stanford Watershed Model, a digital parametric model of the land phase of the hydrologic cycle based on moisture accounting processes. It can be used to simulate annual or longer flow sequences at hourly time intervals. Due to its capability of simulating historical streamflows from recorded climatological data, it has a great potential in the planning and design of water resources systems. However, widespread use of the Stanford Watershed Model …

Quaternary Sedimentation On The Inner Atlantic Shelf Between Cape Henry And Cape Hatteras: A Preliminary Report, Donald J. P. Swift, Gerald L. Shideler, Nicholas F. Avignone, Barry M. Holliday, Charles E. Dill Jr.

OES Faculty Publications

The coast of the Middle Atlantic Bight of North America's Atlantic shelf consists of a series of spit - barrier island systems attached on their northern ends to eroding headlands. It has been suggested that these barriers were generated as coastwise-prograding spits (Fisher, 1967) or alternatively as mainland beaches detached by the Holocene rise of sea level (Hoyt, 1967). The shore face before the barriers consists of fine, seaward-fining sand. Locally, it is corrugated by oblique-trending ridges with up to 8 metres of relief — see for instance CSGS Chart 1109. Beyond the shore face lies a vast submarine sand …

The 51 species consist of 1 species of scaphopod, 13 species in 11 genera of gastropods, 24 species' in 17 genera of bivalves, and 13 species in 6 genera of cephalopods.

The stratigraphy of the Pierre Shale in Bowman County was not compiled into a composite section because of the homogeneity of the shale, the lack of distinctive lithologic units, and the slumped condition of the shale. However, the biostratigraphic position of the Bowman …

Authigenic Analcite In The Golden Valley Formation Southwestern North Dakota, Marvin J. Furman

Theses and Dissertations

Authigenic analcite constitutes up to about 60 percent of a massive, arksosic sandstone exposed on major buttes in the North Dakota Badlands. The analcite constitutes up to about 80 percent of a thin analcimolite bed at the top of the arkose unit. The analcite occurs as spherulites in the interstices of the arkose and as a cement in the analcimolite. Three types of spherulites are recognized: (1) spherulites with an internal radial structure; (2) spherulites with a massive center and a peripheral radial structure; and (3) spherulites lacking an internal radial structure or having a poorly-defined internal structure. The spherulites …

Rates Of Hillslope Lowering In The Badlands Of North Dakota, John R. Tinker Jr.

Theses and Dissertations

Measurements in a small drainage basin in the Little Missouri Badlands of western North Dakota indicate an average rate of hillslope lowering by slopewash of 0.41 inch per year on the west-facing hillslopes underlain by the Sentinel Butte Formation, 0.14 inch per year on the southwest-facing hillslopes underlain by the Tongue River Formation, and 0.11 inch per year on the northeast-facing hillslopes underlain by the Tongue River Formation. Soil creep occurs mainly on the Tongue River Formation and is mostly restricted to the northeast-facing hillslopes where the average rate of soil creep parallel to the hillslope surface is 0.23 inch …

Theses and Dissertations

Rolette County contains approximately 942 square miles in north central North Dakota (Tps. 159-164 N., Rs. 69-73 W.) adjacent to the Canadian border. It includes the southeastern part of the Turtle Mountains and part of the glacial Lake Souris basin. Basic lithologies recognized in the surface sediments were bedded clay, silt, sand, and gravel; and three types of non-bedded diamicton. These were combined and, with bedding characteristics and organic content, formed 15 practical field mapping units. Geologically significant scarps and hill slopes were also mapped. The data collected is shown at a scale of 1 inch to 2 miles. The …

Groundwater Flow In Part Of The Little Missouri River Basin, North Dakota, Thomas M. Hamilton

Theses and Dissertations

The Little Missouri valley in western North Dakota is deeply incised into slightly permeable Mesozoic and Cenozoic sediments. An evaluation of the groundwater flow in part of this valley was 'based on the present groundwater flow-system models. Abrupt changes in the hydrochemical facies have been explained relative to a continuous flow system.

The Little Missouri valley ls the discharge area of a regional groundwater flow system; it affects the potential distribution of the flow system for a minimum of 1.000 feet below the valley floor. The discharge area is approximately the same width as the valley floor and has a …

The Lund Ash-Flow Tuff, John Evans Kreider

Masters Theses

"The Lund Ash-flow Tuff is the uppermost member of the Needles Range Formation, located in southwestern Utah and eastern Nevada. This member can be correlated over an area of several thousand square miles. A detailed study of petrographic and physical features of the Lund show vertical and lateral variations in mineral content and welding intensity. Vertical differences are related to changes in the magma chamber during the Lund eruption interval. Several different ash-flows make up the Lund member. All mineral concentrations vary laterally, with concentration decreasing away from the center of the Lund field. Vertical and lateral variations in physical …

Petrology And Diagenesis Of The Cyclic Maquoketa Formation (Upper Ordovician) Pike County, Missouri, Edwin Carl Kettenbrink Jr.

Masters Theses

"The Maquoketa Formation (Upper Ordovician-Cincinnatian Series) has been extensively studied for over one hundred years, but a petrographic study of its cyclic lithologies has been neglected. The following six distinct Maquoketa lithologies have been recognized in this study in Pike County, Missouri: 1) phosphatic biosparite, 2) phosphorite, 3) micrite-microsparite, 4) dolomitic shale, 5) dolomitic marlstone, and 6) dolomitic quartz siltstone. Three cycle types are present in the Maquoketa. They are expressed as thin beds (1-20 inches) of alternating micrite-shale, micrite-marlstone, and shale-siltstone. Contacts between different lithologies are sharp, indicating a primary sedimentological origin for the cycles. Precisely what mechanism was …
