Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard Jan 1957

Nebraska Deer, William Bailey Jr., George Schildman, Phillip Agee, C. G. Pritchard

Nebraska Game and Parks Commission: Publications

IN COMMON with the experience of most states, Nebraska's deer herds were reduced to a very low level by excessive harvests in our early history. Most American big-game animals were overharvested in the early history of this nation because of commercialization. Buffalo were killed for their hides, deer for their meat. This slaughter continued as long as the hunter (or poacher) could sell his take at a profit. Modem game management and public opinion reversed this trend. Deer are on the way back all over America, and in some states the protection-complex was so strong that deer were restored to …


Influence Of Various Factors On Aggregation Of Peorian Loess By Microorganisms, T. M. Mccalla, Francis A. Haskins, E. F. Frolik Jan 1957

Influence Of Various Factors On Aggregation Of Peorian Loess By Microorganisms, T. M. Mccalla, Francis A. Haskins, E. F. Frolik

Department of Agronomy and Horticulture: Faculty Publications

Soil structure is important in the attainment of adequate aeration for the aerobic microorganisms whose activities maintain such higher plant nutrients as sulfur, phosphorus, and nitrogen in a highly oxidized and thus readily available state. Good soil structure is also necessary for soil and water conservation, Under Nebraska conditions microorganisms and their decomposition products constitute a major source of soil-aggregating agents. The decomposition of crop residues and plant roots is important in the nutrition of these aggregating microorganisms. Other microorganisms, however, also utilize crop residues and plant roots, and they may decompose the aggregating agents as well, so that the …

Economic Analysis Of Forage Production And Utilization In Dakota And Dixon Counties, Nebraska, Howard W. Ottoson Nov 1953

Economic Analysis Of Forage Production And Utilization In Dakota And Dixon Counties, Nebraska, Howard W. Ottoson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Soil erosion remains a serious problem on many Nebraska farms despite programs of financial assistance, technical aid, and education by several national and state agencies. One reason that soil conserving adjustments in land use have not been made by farmers is that considerable uncertainty surrounds the economics of soil erosion control on the farm level. This study is an attempt to increase knowledge and reduce some of the uncertainty with regard to the economics of erosion control in a specific area.


Commercial Fertilizers For Winter Wheat In Relation To The Properties Of Nebraska Soils, R. A. Olson, H. F. Rhoades Jan 1953

Commercial Fertilizers For Winter Wheat In Relation To The Properties Of Nebraska Soils, R. A. Olson, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this bulletin to report the investigations that have been made correlating soil properties and fertilization practices with yields of winter wheat. Since the success or failure of fertilization practices is so dependent on specific soil conditions, an attempt has been made here to further characterize the major soils of the different sections of the state which are devoted to wheat production and to analyze fertilizer practices and results in relation to the soil properties determined. The data are summarized for the four sections of the state designated as southeastern, east-south-central, west-south-central and western Nebraska. These …

Conservation and Survey Division

Recent studies of the stratigraphy and paleontology of the Pleistocene of Nebraska have resulted in additional data that require further clarification and partial revision of the Grand Island sand and gravel formation (1,2) in order that there may be no condusion as the results of varying usage of the term.

Physical And Chemical Properties Of Soil Profiles Of The Burchard And Steinauer Series, Henry W. Smith, H. F. Rhoades Jul 1945

Physical And Chemical Properties Of Soil Profiles Of The Burchard And Steinauer Series, Henry W. Smith, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this bulletin is to report an investigation of the soils mapped as types of the Burchard and Steinauer series. Burchard soils are described as nearly mature Prairie soils, and Steinauer soils as Lithosols, by the Division of Soil Survey. The C horizons of soils of both series consist of calcareous glacial drift. A part of the conclusions drawn from the investigation of these soils is based upon observations made in the field in southeastern Nebraska, the remainder upon laboratory data for samples taken by horizons from nine profiles.

Physical And Chemical Properties Of Soil Profiles Of The Scott, Fillmore, Butler, Crete, And Hastings Series, Henry W. Smith, H. F. Rhoades Jun 1942

Physical And Chemical Properties Of Soil Profiles Of The Scott, Fillmore, Butler, Crete, And Hastings Series, Henry W. Smith, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

For the studies reported here most of the samples were taken in the spring of 1940 from the walls of deep pits dug in areas previously selected by surveyors and inspectors as type locations for the Butler series. To elucidate certain points, samples were taken from the upper part of several other profiles, also called Butler, the following year. In addition to this work on the characterization of the Butler series, further data have been collected concerning soils of the Scott, Fillmore, Crete, and Hastings series. Profile samples were obtained from type locations of each of these series. The data …


The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding Jun 1941

The Geographic Distribution Of Azotobacter And Rhizobium Meliloti In Nebraska Soils In Relation To Certain Environmental Factors, H. B. Peterson, T. H. Goodding

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In this investigation a survey of Nebraska soils has been made in order to determine the distribution of the aerobic nonsymbiotic and symbiotic nitrogen fixers of the genera Azotobacter and Rhizobium respectively. In connection with this survey, some of the characteristics of the soils which may bring about this distribution were studied. Up to this time practically no research has been reported on the microflora of the soils of Nebraska. Hence there is little basis for predicting the activity of these organisms under environmental conditions as they exist here. It is hoped that this work will not only supply some …

A Proposed Method For Classifying And Evaluating Soils On The Basis Of Productivity And Use Suitabilities, Arthur Anderson, A. P. Nelson, F. A. Hayes, I. D. Wood May 1938

A Proposed Method For Classifying And Evaluating Soils On The Basis Of Productivity And Use Suitabilities, Arthur Anderson, A. P. Nelson, F. A. Hayes, I. D. Wood

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the object of this paper to present a method for classifying and evaluating the soils as mapped in regular soil surveys on the basis of land types, which are here defined as areas having reasonably similar productivity and use suitabilities. The standards used to differentiate land types will vary according to the desired objectives, but any material difference in yield, or in practices necessary to maintain a desirable level of productivity will justify recognition of land types. The proposed procedure involves a more detailed study of the influence which soils, slope, erosion, and drainage have on specific crops …
