Journal of the Department of Agriculture, Western Australia, Series 4

TRACE element deficiencies are widespread in Western Australia and application of copper, zinc, molybdenum and cobalt have played a major part in land development in this State.

Research Officer E. N. Fitzpatrick, M.Sc. (Agric.) reviews recent Department of Agriculture research on the use of Trace elements for crop and pasture growth on deficient soils in Western Australia.

A Middle Miocene Rhinoceros Quarry In Morrill County, Nebraska (With Notes On Hip Disease In Diceratherium), Robert M. Stecher, C. Bertrand Schultz, Lloyd G. Tanner

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

Extensive deposits of fossil rhinoceros bones have been excavated from University of Nebraska State Museum collecting localities Mo-113, -114, -115, -116, and -118 some 8 1/2 to 9 1/2 miles north of Bridgeport, Morrill County, Nebraska. The fossils were associated with other faunal elements in the lower portion of the Marsland formation (middle Miocene) of the Hemingford group. The rhinoceros is considered to be Diceratherium niobrarensis Peterson, geologic variety. A pathologic right femur of D. niobrarensis provides evidence of hip disease in the medial Miocene rhinoceroses.

Early Records Of Some Mammals From Nebraska, J. Knox Jones Jr.

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

Ten species of Recent mammals that formerly occurred in Nebraska have been extirpated there by European man. Surprisingly few specimens of the species concerned are preserved in museum collections. Perusal of a representative segment of the historical literature pertaining to Nebraska has revealed records of occurrence of most of the extirpated species that provide a basis for estimating the former distribution of each in the State.

Seismic Investigation Of Flint Clay Deposits In East Central Missouri, Roland D. Dayley

Masters Theses

"Seismic refraction surveys were conducted in several localities within the east central Missouri clay districts in order to determine the applicability and economy of this method as a clay exploration tool. Results of these surveys revealed that the sink-type clay deposits possess lithologic and structural characteristics that lend themselves favorably to this method of exploration.

Seismic records obtained from profiles shot across known deposits indicate that several factors other than velocity contrast serve to produce apparent seismic anomalies.

Some unforeseen time loss and expense was encountered because of malfunctions of the seismic equipment employed, which necessitated the purchase and installation …

Light Lands In Western Australia. 1. History And Future Prospects, F L. Shier

Journal of the Department of Agriculture, Western Australia, Series 4

BECAUSE of the scattered distribution of light lands of the agricultural areas of Western Australia among the better soils, and their large total area, it is not surprising that attempts to develop these unattractive soils for agriculture started many years ago.

The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Naturalists for many years have known that birds sing most at dawn and at dusk, but to which of many physical variables they are responding has not been completely determined. This problem has taken on importance in the field of wildlife management because calling rate has been used as an index of abundance for numerous game birds, namely the Pheasant, Phasianus colchicus (Kimball, 1949); the Mourning Dove, Zenaidura macroura (McClure, 1939); the Bobwhite Quail, Colinus virginianus (Bennitt, 1951; Rosene, 1957): and the Woodcock, Philohela minor (Pitelka, 1943).

Influence Of Compaction And Freezing On The Structure And Permeability Of Some Selected Horizons From Northern Utah Soils, Samir Ramzy Nagmoush

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Frequently, in evaluating plant deficiencies, one considers only those soil factors which are associated with the fertility of the soil-- mainly the levels of phosphorus, potash, nitrogen, and organic matter. A certain level of nutrition is essential for plant growth, but in order for the nutrients to exert their maximum influence on the productivity of the soil, it is equally important that a good soil environment be provided and maintained. A good environment requires that good physical conditions of soil, sir, and water be in balance.

Copper Minerals For Fertilizer Use, R N. Glencross

Journal of the Department of Agriculture, Western Australia, Series 4

COPPER fertilizers have an important role in maintaining: and increasing Western Australia's agricultural production.

On many soils they are essential for cereal growing or pasture production and persistence and for animal health and wool quality.

They are also sometimes used for fruit trees, vines, and vegetables.

Fossils And Farmers, D Merrilees

Journal of the Department of Agriculture, Western Australia, Series 4

The West Australian Museum is looking for fossil remains from the Pleistocene age, the period of geological time when Europe was covered with ice.

Little is known of what the Australian continent was like at that time, and the Museum hopes, by collecting as many fossil remains as possible, to get a better picture of Australian conditions at that time.

It is also hoped to discover more about the ancestors of our present marsupial fauna.

Farmers may be able to make a valuable contribution to the present knowledge of this period by forwarding suspected fossil remains to the Museum. Here …

Correcting Cobalt Deficiency, Laurence C. Snook

Journal of the Department of Agriculture, Western Australia, Series 4

COBALT is essential in the food eaten by sheep and cattle. As little as one part of cobalt in 10,000,000 parts of food appears to be adequate.

But if this mere trace is missing, ruminants will waste away and die, even when the feed appears excellent In every other way.

Establishing Saltland Pastures, C V. Malcolm

Journal of the Department of Agriculture, Western Australia, Series 4

WITH the approach of winter, thoughts are turning to the seeding season. It will therefore be appropriate to discuss methods of establishing saltland pastures.

This discussion will be restricted to "bluebush," creeping saltbush, and old man saltbush. Seed of these plants is available from local stock firms.

Potassium Deficiency In Medium Rainfall Areas, William John Toms

Journal of the Department of Agriculture, Western Australia, Series 4

IT is well known that potassic fertilisers must be used for the successful growth of subterranean clover (Trifolium subterraneum L.) on many soils in the higher rainfall districts of Western Australia.

Recent investigations have shown that some soils in medium rainfall districts are also too low in potassium to grow healthy subterranean clover pastures.

Fossils And Farmers. 2. The Ice Age, D Merrilees

Journal of the Department of Agriculture, Western Australia, Series 4

What did the giant Australian marsupials of the "Ice Age" look like?

Fossil remains found by farmers could help reconstruct them, as well as giving some idea of conditions on the Australian continent at that time, says D. Merrilees, B.Sc, acting Curator of Palaeontology at the West Australian Museum.

The Use Of Lime In Market Gardens, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THE term "lime" when used in relation to agriculture means any calcium containing material that is capable of correcting soil acidity.

While generally used for this purpose, lime has many other equally important functions in the soil.

Certain Trace Element Distribution In The Searchlight, Nevada Quartz Monzonite, Clark County, Nevada, Jai Nandan Shrivastava

Masters Theses

"The once prosperous gold, silver, copper and lead mines of the Searchlight mining district, Nevada, are situated along the south and western margins of a large quartz monzonite body. This intrudes the Precambrian gneisses and younger lava flows. Associated mineral veins show an eccentric type of zoning around the intrusive.

Seven rock samples of the quartz monzonite representing different parts of the intrusive were analyzed petrographically and spectrographically. Modal analyses and various types of rock alteration were investigated petrographically. Spectrochemical analyses of the rock samples and their major minerals were carried out for certain trace elements. A semi-quantitative method was …

Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.

Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.

Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

Studies In Iron Chlorosis Of Leaves, Narayan Gunderao Perur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Normal healthy growth and development of plants is controlled by certain factors known as factors of plant growth. They are soil, climate, and plant inheritance. The soil contains many nutrient elements needed by plants both in macro and micro quantities. Iron is one of the essential elements required by plants in small amounts.

When plants are starving for any of the essential nutrients, characteristic symptoms usually appear as certain abnormalities, discoloration and deformation of leaves, fruits, and other parts. The deficiency symptoms, though not easily recognizable in some cases at the beginning, are quite apparent in advanced stages of plant …

Reclaiming Salt Land With Bluebush, Stanley Thomas Smith

Journal of the Department of Agriculture, Western Australia, Series 4

IN Western Australia there are approximately a million acres of salt land, some of which is a serious economic problem to individual farmers, unfortunate enough to have the major portion of their properties affected by salt encroachment.

Cyclic Sedimentation Of The Upper Fayetteville Formation, Faramarz Frouzan

Masters Theses

"In the past decade considerable interest has developed in the geology of the Boston Mountain area of northern Arkansas. This has been due to exploration for oil and gas in-the area and the related desire to know more about the structure and stratigraphy of the region. Principal work has been done by the University of Arkansas, the United States Geological Survey, and oil companies. This study involves only one of the formations making up the geologic column in the Boston Mountains, the Upper Mississippian (Chesterian Series) Fayetteville Formation.

Portions of the upper part of the Fayetteville Formation of northwestern Arkansas …

Soil Conservation In The Kimberley Area Of Western Australia, K Fitzgerald

Journal of the Department of Agriculture, Western Australia, Series 4

OFFICERS of the Soil Conservation Branch of the West Australian Department of Agriculture, have not been engaged in soil conservation work in the Kimberleys prior to this year, not because a serious erosion problem did not exist, but rather because with limited trained staff available they were too fully occupied elsewhere.

The recent arrival of a senior Soil Conservation Officer in the area to assist and plan an approach to the problem of soil erosion in the Ord River catchment area is therefore very welcome.

Mississippian Bioherms Of Southwestern Missouri And Northwestern Arkansas, Arthur R. Troell Jr.

Masters Theses

"Lenticular bodies of massive limestone, flanked by thin crinoidal beds, crop out in southwestern Missouri and northwestern Arkansas. They are within the St. Joe limestone of the Lower Mississippian.

Strata underlying these bodies typically are down-warped, those on the flanks lapping against, finally passing completely over the limestone core. Dips away from the “reef” are commonly around 5 degrees, but reach as much as 30 degrees. Conglomeratic detritus, originating from the core, occurs in flanking beds at their contact with it.

Thin sections of these masses show no more than 15 per cent of the limestone to consist of fossil …

Early History Of Malad Valley, Glade F. Howell

Theses and Dissertations

The Malad Valley is geographically located in a unique position in the Pacific Northwest. The Bear River and its main affluent, the Malad River, are the only rivers in the Pacific Northwest that drain into the Great Basin, whereas the other streams and rivers of the states of Washington, Idaho, and Oregon empty eventually into the Pacific Ocean. It is also characterized for being the northern end of prehistoric Lake Bonneville, and eventually it was through this valley that an outlet opened to drain the lake. The soil deposits from this lake left a fertile valley, capable of producing most …

Geology Of The Upper Middle Creek Area Huerfano County, Colorado, J. H. Copeland

Open Access Master's Theses (through 2010)

The Sangre de Cristo Mountains of Colorado and New Mexico are, geologically speaking, relatively unknown. The equivocal nature of our knowledge of the range was a primary reason for studying a portion of it in some detail. Most of the previous studies have been concerned with the northern part of the range in Colorado, in the general area between Salida and La Veta Pass. This work has indicated that the complicated structure which characterizes the northern part of the range becomes simpler to the south. Therefore, a second objective of the current study has been to test this hypothesis. Thirdly, …

A Review Of Fossilization Processes In Different Sedimentary Environments (With Special Reference To The Time Factor Of Deposition Of Ore Minerals Associated With Fossil Material, In Particular The Coprolitic Phosphate Deposits), Giovanna Reggiori Ligasacchi

Masters Theses

"This thesis offers a cross/section through some principal fossilization processes involving organic matter (animals and plants) during and after sedimentation. The influence of different environments during fossilization is considered. The chemical composition of some classes of living invertebrates and plants is compared with the chemical composition of same organisms as found in consolidated sediments as fossils.

Some literature on carbonates, oxides, silicates, phosphates, and sulphides in fossils is reviewed with particular attention to those instances where the fossils are associated with ore minerals. Special consideration is given to the occurrence and composition of fecal matter in recent and consolidated sediments. …

Gastropoda From The Pierre Shale (Upper Cretaceous) Of Emmons County, South-Central North Dakota, Alan M. Cvancara

Theses and Dissertations

Fossil gastropods were studied from the upper part of the Pierre shale (Upper Cretaceous) in Emmons County, south-central North Dakota. This primary purpose of this study was to figure all gastropods found and bring the nomenclature of up to date. Secondly, an attempt was made to determine whether these fossil gastropods could be used in defining the contact between the Pierre shale and overlying Fox Hills sandstone.

Little paleontological work has been done on Pierre gastropods in North Dakota. Identification previously made seem to have been done somewhat hurriedly from Meek (1876) with little regard to modernizing the nomenclature.

These …
