Nebraska Green Quartzite An Import Ant Future Industry, Erwin H. Barbour Jan 1915

Nebraska Green Quartzite An Import Ant Future Industry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

ln southern Harlan and Franklin counties, there occur many acres of green quartzite which must be of commercial consequence when made available. It is a neglected resource upon which important industries are sure to be based. With the development of this bed in view, the Nebraska Geological Survey has examined this area. and through this leaflet wishes to place the results before possible investors.


Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour Jan 1915

Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

This leaflet it intended to serve as an answer to correspondents who make inquiry about the rocks of Nebraska1. Unfortunately for those interested in such matters, the rocks of the State are few in number, and are deeply buried from view by sand and soil, so there are thousands of square miles in which even a pebble is a rarity. That our rocks are level and undisturbed is practically true. Still there are some surprisingly interesting folds and faults.


The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr Jul 1914

The Storage And Use Of Soil Moisture. Report Of Experimental Substation, North Platte, Nebraska, W. W. Burr

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The profitable cultivation of the non-irrigable lands in west central and western Nebraska is limited by the amount and efficient use of the precipitation. There are tracts of land in the sand hills and minor tracts of badly worn heavier soils where the need of soil fertility is becoming evident. But, in the main, the great problem at present is not one of soil fertility, but of how to get enough water to make use of the fertility now present. The rainfall of this section, which varies from an actual shortage to seldom more than a meager sufficiency, makes it …


Bulletin No. 134 - The Nitric Nitrogen Content In The Country Rock, Robert Stewart, William Peterson Jun 1914

Bulletin No. 134 - The Nitric Nitrogen Content In The Country Rock, Robert Stewart, William Peterson

UAES Bulletins

In many arid sections of Western America there have been reported marked accumulations of nitrates in the cultivated soil. Hilgard,(1) who was the first to observe these accumulations, believed that the nitrates are being formed at the present time by the rapid nitrification of the organic matter contained in the soil. In Colorado there has been considerable trouble with orchards dying; the death of the trees in some cases has been attributed to the excessive accumulations of nitrates in the cultivated soil. These accumulations are due, according to Dr. Headden,(2) to the fixation of atmospheric nitrogen by bacteria now at …

Notice Of Jelly Fishes In The Carboniferous Of Nebraska, Medusina Walcotti, Erwin H. Barbour Jan 1914

Notice Of Jelly Fishes In The Carboniferous Of Nebraska, Medusina Walcotti, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

In visiting the quarries of the State, certain quadripartite objects suggesting the form of jelly fishes have long attracted the writer's attention. They are large and coarse, and were assumed to be imitative concretions. However, the total number observed seems to strengthen the probability that they are of organic origin. In the fall of 1913, while conducting a field class through the Burlington Quarries, located about two miles northwest of South Bend, they were noted again in a new locality, and three specimens were obtained. Two of these were unusual examples, and showed sufficient structure to identify them with the …


Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always Jun 1913

Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always

Nebraska Agricultural Experiment Station: Historical Research Bulletins

These experiments were carried out in connection with and subordinate to various soil investigations, the object being to determine the relation of the final water content of the soil to the hygroscopic coefficient and to determine to what extent the moisture was removed from the different portions of the subsoil not penetrated by plant roots.


Bulletin No. 122 - The Nature Of The Dry Farm Soils Of Utah, John A. Widtsoe, Robert Stewart Jan 1913

Bulletin No. 122 - The Nature Of The Dry Farm Soils Of Utah, John A. Widtsoe, Robert Stewart

UAES Bulletins

Successful farming in Utah is dependent upon two main factors: First, the economic use of irrigation water upon the lands lying under the irrigation ditch, and second, upon the correct practice of the principles of dry farming upon those lands not susceptible to irrigation. Dry farming in Utah is, therefore, of great importance and it becomes essential to learn something of the nature of the dry farming soils of the State.


Bulletin No. 121 - The Soil Of The Southern Utah Experiment Station, John A. Widtsoe, Robert Stewart Jan 1913

Bulletin No. 121 - The Soil Of The Southern Utah Experiment Station, John A. Widtsoe, Robert Stewart

UAES Bulletins

The soil of the Southern Utah Experiment Farm is a very interesting type: it is highly charged with gypsum and thereby presents a condition unique in reported studies of the soils of America. Gypsiferous soils are characteristic of a large portion of Southern Utah; many of them are derived from shale, others from sandstone, impregnated with gypsum.


Cement Manufacture In Nebraska, Erwin Hinckley Barbour Jan 1913

Cement Manufacture In Nebraska, Erwin Hinckley Barbour

Conservation and Survey Division: Faculty and Staff Publications

It is the purpose of this paper to briefly review the history of cement manufacture in the State, to call attention to certain promising exposures of cement rock, and to report upon the first modern cement mill in Nebraska. Not that this State has been slow in recognizing cement as one of the most important modern constructional materials; or slow to recognize the need of developing its natural resources; but due rather to a combination of circumstances. For at least twenty years, many Nebraskans have had in mind the importance of establishing cement plants in this State. Furthermore encouraging inducements …


Bulletin No. 115 - The Movement Of Water In Irrigated Soils, J. A. Widtsoe, W. W. Mclaughlin May 1912

Bulletin No. 115 - The Movement Of Water In Irrigated Soils, J. A. Widtsoe, W. W. Mclaughlin

UAES Bulletins

This bulletin embodies a part of the data secured in the irrigation investigations of this Station. It aims to contribute something to our knowledge of the movement of water in irrigated soils . The science of irrigation can not well be built until the laws involved in the mutual relationships of waters, soils and crops are understood with fair accuracy. Much has been done by numerous investigators, during the last fifty years, to give a clearer comprehension of the movement of soil moisture; but the field experiments have dealt largely with saturated soils, and the laboratory experiments have seldom taken …


Bulletin No. 114 - The Movement Of Nitric Nitrogen In Soil And Its Relation To "Nitrogen Fixation", Robert Stewart, J. E. Greaves Dec 1911

Bulletin No. 114 - The Movement Of Nitric Nitrogen In Soil And Its Relation To "Nitrogen Fixation", Robert Stewart, J. E. Greaves

UAES Bulletins

In the spring of 1903, we commenced at the Utah Experiment Station a series of experiments, the purpose of which was to study the development and movement of nitrates in irrigated soil. The work was so outlined that it should give some very definite results, both as to the influence of water and the plant, upon the nitric nitrogen content of the soil.

Bulletin No. 109 - The Nitrogen And Humus Problem In Dry-Land Farming, Robert Stewart

UAES Bulletins

The effect of cultivation and the growth of crops upon the nitrogen and humus content of soils has been studied by various investigators, both in America and Europe. In general, the results of the various investigations indicate that cropping and cultivation are very destructive of the organic. matter and the nitrogen of the surface soil.

Bulletin No. 106 - A Study Of The Production And Movement Of Nitric Nitrogen In An Irrigated Soil, Robert Stewart, J. E. Greaves

UAES Bulletins

The problem of maintaining the nitrogen content in our agricultural soils is one of vital importance to the development of a permanent system of agriculture. Any investigation, therefore, which tends to throw any light on the conditions which are necessary for maintaining the maximum supply of nitrogen in our soils needs no apology for its institution.

Bulletin No. 104 - The Storage Of Winter Precipitation In Soils, John A. Widtsoe Oct 1908

Bulletin No. 104 - The Storage Of Winter Precipitation In Soils, John A. Widtsoe

UAES Bulletins

It has been found that the production of one pound of dry plant substance on soils of average fertility, requires in humid districts not more than five hundred pounds of water, and in arid districts like Utah about seven hundred and fifty pounds. This indicates that the average rainfall of Utah, which is about twelve inches, if properly conserved in the soil, is sufficient to produce annually, without irrigation, from thirty to forty-five bushels of wheat to the acre, or corresponding yields of other crops. The realization of this truth has changed greatly our views of irrigation practices. The beginning …

On The Origin And Definition Of The Geologic Term "Laramie", A. C. Veatch Jan 1907

On The Origin And Definition Of The Geologic Term "Laramie", A. C. Veatch

United States Geological Survey: Staff Publications

INTRODUCTION

Investigations of the United States Geological Survey during the summer of I906, covering the larger part of the Laramie exposures on the Laramie Plains, examined by the King and Hayden surveys, have revealed many new and important facts bearing on the Laramie problem.

By detailed areal surveys it was found: (1) that the lignitiferous series, which in the Laramie Plains lies between the Montana below and the Fort Union above, and has a maximum thickness of about 12,500 feet, is divided about the middle by an unconformity; (2) that this unconformity is in the same stratigraphic plane and continuous …

Biennial Report, Erwin H. Barbour Jan 1907

Biennial Report, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

The Nebraska Geological Survey as now constituted has been in operation since 1891, but it has enjoyed state aid during the past four years only. Considering the size of the commonwealth and the limited appropriations for geological work, unusual progress has been made. Since no report covering the work of the first biennium was prepared it will be included incidentally in this paper. Briefly stated the Nebraska Geological Survey during the past biennium has devoted especial attention to the industrial resources of the state, prepared ten o! twelve reports in manuscript form, published eight reports completing volumes I and II, …

The Morrison Formation And Its Relations With The Comanche Series And The Dakota Formation, T. W. Stanton Jan 1905

The Morrison Formation And Its Relations With The Comanche Series And The Dakota Formation, T. W. Stanton

United States Geological Survey: Staff Publications

The beds now generally designated on U. S. Geological Survey maps as the Morrison formation have been a subject of interest and discussion since I877, when abundant remains of dinosaurs were found in them. The first extensive collections of the vertebrate fauna were obtained in the neighborhood of Morrison near Denver, -in Garden Park, near Canyon City, Colorado, and at Como, or Aurora, Wyoming. Since then the formation has been recognized by means of its fossils, its lithologic features, and its stratigraphic relations in the Black Hills, on the Laramie Plains, and elsewhere in Wyoming, in Montana, in western Colorado, …
