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.

Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel Aug 1943

Nitrate Production As Affected By Grain-Crop Residues On The Surface Of The Soil, T. M. Mccalla, J. C. Russel

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of this bulletin is to present the data on nitrate contents and nitrate production in tests where straw or stalk residues were left on the surface through subsurface tillage, as compared with check treatments where these residues were plowed under or were absent. Nine of these tests were at Lincoln, Nebraska, and one was at the Hastings, Nebraska, Hydrological Project. Two tests were conducted in 1939, four in 1941, and four in 1942.

Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead Jul 1942

Vegetation Of The Northern Part Of Cherry County, Nebraska, William L. Tolstead

Conservation and Survey Division

Agricultural practices in the Great Plains of North America are now in a period of adjustment from a traditional agriculture initiated by pioneer farmers to a grazing economy based upon potentialities of climate and soil. The attainment of a proper system of land use has been retarded in many localities by the lack of definite information concerning the vegetation and its indicator significance. In this study of the vegetation of Cherry County, Nebraska, the interrelations between the plants and their environments are discussed, the dominant species are described, and changes in grasslands caused by seasons, grazing, and climatic cycles are …


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 …


Zinc Relationships Of Some Utah Soils, Wilford Derby Laws Jr. May 1941

Zinc Relationships Of Some Utah Soils, Wilford Derby Laws Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent reports from many parts of the United States indicate that the so-called zinc-deficiency disease is wide spread. It affects some varieties of trees in some areas and all varieties in other areas, and occurs from Florida westward to the Pacific coast and northward to the Canadian line. Although the disease is more prevalent in trees, it is also known to affect annual plants.

A recent survey of Utah orchards shows a wide-spread occurrence of little-leaf, a zinc deficiency disease, in fruit trees. The disease was found to be common on the upper sandy soils between Ogden and Salt Lake …

Effect Of Organic Matter Decomposition On The Solubility And Fixation Of Phosphorus In Alkaline Soils, H. F. Rhoades Jun 1939

Effect Of Organic Matter Decomposition On The Solubility And Fixation Of Phosphorus In Alkaline Soils, H. F. Rhoades

Nebraska Agricultural Experiment Station: Historical Research Bulletins

It is the purpose of this bulletin to report a laboratory study on the effects of organic matter decomposition on the solubility and fixation of phosphorus in alkaline soils. The study included the following: (1) a comparison of the effects of a decomposing organic material with those of a physiologically acid nitrogen fertilizer, and (2) a comparison of the effects of different organic materials of varying phosphorus contents.


Effect Of Soil Type, Slope, And Surface Conditions On Intake Of Water, F. L. Duley, L. L. Kelly May 1939

Effect Of Soil Type, Slope, And Surface Conditions On Intake Of Water, F. L. Duley, L. L. Kelly

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In connection with investigations of runoff and erosion in the Great Plains an attempt has been made by means of artificial applications of water to determine certain principles concerning the effect of different soils and soil conditions on runoff and soil erosion. Such information is needed in planning all field operations dealing with soil erosion and moisture control. It is also needed in connection with watershed studies that are being established in the Central Great Plains, dealing with runoff and flood flows from larger areas. The method employed makes it possible to obtain comparable data on a wide range of …


An Outline Of The Principal Natural Resources Of Nebraska And Their Conservation, George E. Condra Jan 1939

An Outline Of The Principal Natural Resources Of Nebraska And Their Conservation, George E. Condra

George E. Condra Publications

Nebraska is well endowed with important natural resources, such as stone, clay, sand, soil, water, prairie, forests and wildlife. However, soil and water are our basic heritage because they, more than other resources, support native life, agriculture, industry, and social development.
