EC38-118 Soil and Moisture Conservation in Nebraska

When the white men first explored Nebraska, they found little erosion taking place. They found the hills, particularly in eastern Nebraska, covered with a dense growth of grass, underlain with a thick mat of decaying debris. The valleys were even more densely covered with the water-loving grasses and sedges. The soil underneath and prairie was black and soggy, the result of centuries of accumulating humus. The valleys bordernig the streams were boggy and abounded with springs. Clear water flowed constantly in the streams. The upland draws in the more favorable parts of the state were heavily covered with the big bluesteam and slough grass. Springs occurred in many of these. Soil erosion in Nebraska has not progressed to as great an extent as in states to the east and to the south. This is because of the comparatively lower rainfall in Nebraska, because the land has been farmed for fewer years in this state, and because some Nebraska soils are comparatively less erosive. This extension circular covers the factors which influence erosion, erosion control practices and storage of soil moisture.

EC31-133 The Management of Nebraska Soils (Revised March 1936)

The agricultural lands of this country are its greatest natural resource. History points out that nations with vast areas of good farm land are most likely to prosper and survive over long periods of time. Local communities, too, prosper and flourish in proportion to the productiveness of the surrounding land. Schools, social life, and business develop best in areas where the land is productive and properly managed and conserved. Nebraska, in common with other states, has suffered by the depletion of soil fertility. The reduction in acres in legumes and grasses, and the deplation of the organic matter in the surface soils, has likewise had its effect on the run-off of precipitation, soil blowing, and damage from drouth. In order to know what elements of fertility may become deficient and how soil fertility may be restored and maintained, we should understand the composition, character, and management of soils. In the following pages, some fundamentals of soil feritlity are given, followed later by a discussion of practical soil-management practices.

RB31-258 The Contribution fo Nebraska Farm Women to Family Income Through Poultry and Dairy Products

This investigation was made in 1929-1930 for the purpose of studying the activities of Nebraska farm women in the raising of poultry and in the care of dairy products, to discover whether or not such activities resulted in a contribution to the family income. With this in view, a group of women were asked to keep records for one year (from April 1, 1929 to March 31, 1930) of the value and amount of dairy and poultry products sold or used, of all expense incurred in production, and of the time spent both by the homemaker herself and by all other members of the household, in the production and sale of dairy and poultry products. When this study was outlined it was intended to cover only actual cash addition to the family income. This, however, did not prove to be feasible, as a considerable portion of the contribution to the family income was in the form of dairy and poultry products used at home.

EC24-721 Dairy Barns for Nebraska

The increasing interest shown among the farmers thruout this state in the betterment of dairy stock, and the tendency to give more attention to dairying on the farms, is bringing to the Agricultural College a great many requests for plans and suggestions for dairy barn construction. It is impossible to give every one of these inquiries individual attention to the extent of drawing a detailed plan to suit the conditions in each case. It is hoped therefore, that the material contained in this bulletin will offer helpful suggestions and answer many questions in the minds of prospective dairy men and dairy barn builders relative to the arrangement and construction of barns.

RB34-71 Effects of Inflation and Deflation Upon Nebraska Agriculture, 1914 to 1932

Nebraska farmers prospered during the period which followed the depression of the nineties and preceded the beginning of the World War. To be sure the prosperity was not uniformly distributed either by years or by areas. The corn crop was unusually short in a large portion of the state in 1901 and an almost total failure in many of the southern counties in 1913. Chinch bugs did considerable injury in 1901 and the Hessian fly in 1905 and 1914. There was noticeable damage from insects in some areas in other years. No part of the state, however, suffered from long-continued drouth or repeated ravages of insect pests. The depression of 1907 affected credit and prices very severly for a few months, but recovery was rapid and within less than a year business was again moving forward. This 1934 research bulletin covers the problems of inflation and deflation; changes in the prices of various commodities during inflation and deflation; prices and purchasing power of Nebraska farm products, 1914 to 1932; adjustments during inflation and deflation; the effect of wages on Nebraska agriculture; taxes; Nebraska farm income; changes in types of farming in Nebraska, 1914 to 1932; the banking situation; Nebraska farm land prices; and the effects of inflation and deflation upon Nebraska businesses.

EC33-136 Corn in Nebraska

Corn is Nebraska's most important crop. Of the nearly 19 million acres under cultivation in the state, over 10 million acres or more than 50 percent is normally planted to corn. This is three times the acreage of wheat, four times that of oats, and ten times that of barley. The 10-year average acre yield of corn for this state is 25.8 bushels compared with 26.9 bushels for the entire United States. Nebraska, with an average annual crop of approximately 258 million bushels, usually ranks third among all states in the total production of corn, being exceeded by Iowa and Illinois. This 1933 extension circular discusses the importance of corn, seed, varieties of corn, freezing injury, testing seed corn, hybrid corn, soil fertility and rotation, cultural practices, harvesting and storing corn, power machinery in relation to costs in corn production, corn diseases and insects, and utilization of corn.

The Nebraska Agricultural Outlook for 1938

Each year the federal government gathers data relating to agriculture through the various departments of the United States Department of Agriculture. These data are classified and analyzed by the Bureau of Agricultural Economics at Washington and all information which may be helpful to farmers is published. For several years it has been the policy of the Department of Rural Economics and the Agricultural Extension Service of the College of Agriculture, Lincoln, to select from the federal information facts which may be especially helpful to Nebraska farmers. These facts and other economic conditions in Nebraska are published this year as the Agricultural Outlook for Nebraska, 1938. The Outlook should be helpful in the marketing of the crops and livestock on hand. It should also be helpful in making farm plans for 1938.

Forty-eighth Annual Report of the Agricultural Experiment Station of Nebraska, February 1, 1935

This report differs from previous reports in two respects: it covers experimental work up to January 1, 1935, and it includes brief abstracts of publications since the last report. Previously most of the report dealt with work done before the end of the fiscal year; that is, work done between June 30 and January 1 was not reported until over a year later, for the most part. The present report corrects that defect, and in addition the abstracts of publications will make the report useful as a reference guide to published matter. The projects are discussed under subject headings and in addition to the abstracts, brief reports of progress in projects under way are included. Complete data for these projects are not included; rather an attempt has been made to show how far the work has gone and to indicate some of the directions or trends of the work. The drouth of the past summer reduced yields severely. As a result the collection of significant data on yields was almost impossible. A few of the Experiment Station workers have ben loaned to federal projects. Despite these handicaps many projects have been advanced and many have been completed.

Forty-Fifth Annual Report of the Agricultural Experiment Station of Nebraska, February 1, 1932

This report covers the investigations, expenditures, and publications of the Nebraska Agricultural Experiment Station for the fiscal year June 30, 1931. During the year 68 projects have been under investigation at the main station. These have covered a wide range of subjects. At the various substations the work is planned to meet the needs of the different regions. The funds for carrying on the work of the stations are derived from federal and state sources. The work is carried on in definite projects according to the supporting fund. Satisfactory progress was made on the research program. During the year eight projects were completed and seven new ones added. The selection of new projects is on the basis of most urgent need, together with the ability of the Experiment Station to carry the project. The financial depression in which agriculture still finds itself has increased rather than decreased the demand upon the Experiment Station and the College for new and definite information. This demand has been taken care of insofar as possible. During the year covered by this report eleven bulletins, nine research bulletins, and one circular have been published by the Experiment Station. In addition 22 technical papers have been prepared by members of the staff and printed in various technical and professional journals.

Comparison of Botanical Composition, Soil Carbon Content, and Root Distribution of Subirrigated Meadows in The Nebraska Sandhills

Characterizing vegetation composition, carbon/nitrogen (C/N) content of soils, and root-mass distribution is critical to understanding carbon sequestration potential of subirrigated meadows in the Nebraska Sandhills. Five subirrigated meadows dominated by cool-season (C3) graminoids and five meadows dominated by warm-season (C4) grasses were selected throughout the Nebraska Sandhills. Vegetation, soil carbon and nitrogen, and root-mass density distribution were sampled in each meadow. Meadows dominated by C3 vegetation had 12% greater (P < 0.1) yields than meadows dominated by C4 vegetation. Total root-mass density was 30% greater (P < 0.1) in C4-dominated meadows than C3-dominated meadows. Total carbon and nitrogen content was 65% and 53% greater (P < 0.1), respectively, in the A horizon of C3-dominated meadows, but was 43% and 52% greater (P < 0.1), respectively, in the C horizon of C4-dominated meadows. Although meadows dominated by C3 vegetation had more carbon in the soil profile, much of the carbon in C3-dominated meadows appeared to be recalcitrant C4 carbon from historic vegetation.

Sulfate Mineral Paragenesis in Pennsylvanian Rocks and The Occurrence of Slavikite in Nebraska

The acid weathering of pyrite-bearing Pennsylvanian clastic sedimentary rocks in southeastern Nebraska locally produces the secondary sulfate minerals alunogen, copiapite, epsomite, felsobanyaite/basaluminite, gypsum, halotrichite, jarosite, rozenite, and slavikite. Of these mineral occurrences, four are first-time discoveries in the state or the surrounding region. Slavikite (NaMg2Fe5 (S04)7 (OH) 6• 33H20), which has been reported only once before in North America and from a handful of sites in Europe and South America, was found in abundance at an outcrop at Brownville, NE. The pH values in 1:1 solutions of deionized water of the studied minerals, excluding epsomite, range from 1.94 to 4.82. Therefore, segregations of secondary minerals in themselves are significant microenvironmental reservoirs of acid that can be mobilized during precipitation events. Because of its role in liberating and concentrating ions such as Al3+, Fe2+, Fe3+, Mg3+, and SO42-, acid rock weathering should be considered in local to regional assessments of surface-water and groundwater chemistry. Observations also suggest that rock weathering by the growth of sulfate salts is a potential factor in local hillslope development, one that has not previously been considered in the study area.

Portraits of Protestant Teens: A Report on Teenagers in Major U.S. Denominations

This report examines the religious beliefs and practices of American Protestant teenagers using new, nationally representative survey data from the National Study of Youth and Religion (NSYR). The NSYR is a major study of the religious and spiritual lives of contemporary American teens, which recently produced a book on its major findings entitled, Soul Searching: the Religious and Spiritual Lives of American Teenagers (by Christian Smith with Melinda Lundquist Denton, Oxford University Press, 2005). In addition to broadly describing the religious outlook of Protestant teenagers today — and as a more detailed, descriptive follow-up to that book — this report highlights several positive and negative experiences and evaluations of teenagers in different Protestant denominations and groupings of denominations. In brief, this report presents the following findings in these areas of interest: ♦ Religious Participation: Protestant teenagers are relatively active in religious organizations and activities, both within and beyond their churches. About one-half of all Protestant teens attend church weekly, participate in Sunday school or in a religious youth group, pray and attend a religious summer camp or retreat, though less than one-third read the Bible each week. This also means, however, that substantial numbers of Protestant teens are not actively participating in their religious traditions. Teens from conservative denominations such as Southern Baptist Convention and Assemblies of God are especially likely to regularly attend church and participate in other religious activities. ♦ Theological Beliefs: Protestant teenagers are likely to hold many traditional Christian religious beliefs. The majority of Protestant teens say they believe in God, the afterlife, angels, demons, miracles, judgment day and they view God as a personal being involved in the lives of people today. Sizable numbers of Protestant teens, on the other hand, do not hold these traditional Christian religious beliefs. Teens from conservative and black Protestant denominations are more likely than mainline Protestant teens to hold these religious beliefs. ♦ Importance of Faith: The majority of Protestant teenagers report that their religious faith is very important in their lives. Most of them also say that their families talk about religion together, that they have shared their faith with someone not of their faith and that they have had a powerful worship experience. A large minority of all Protestant teenagers, and in the case of some denominations a majority of teenagers, do not report that religious faith is very important in their lives. Teens from conservative and black Protestant denominations are particularly likely to report that faith is important in their lives. ♦ Evaluations of Churches: The majority of Protestant teenagers express relatively positive views of their churches and fellow church members. They typically report that they would continue to attend church if it were totally up to them, that they would attend a similar church if given the choice and that their current church is generally warm and welcoming. Protestant adolescents, however, do have some reservations about and problems with their churches and fellow church attendees, as spelled out in the following pages, particularly with other teenage attendees.

Hydrogeologic Setting and Ground-Water Flow Simulations of the Eastern High Plains Regional Study Area, Nebraska

The transport of anthropogenic and natural contaminants to public-supply wells was evaluated in a part of the High Plains aquifer near York, Nebraska, as part of the U.S. Geological Survey National Water-Quality Assessment Program. The aquifer in the Eastern High Plains regional study area is composed of Quaternary alluvial deposits typical of the High Plains aquifer in eastern Nebraska and Kansas, is an important water source for agricultural irrigation and public water supply, and is susceptible and vulnerable to contamination. A six-layer, steady-state ground-water flow model of the High Plains aquifer near York, Nebraska, was constructed and calibrated to average conditions for the time period from 1997 to 2001. The calibrated model and advective particle-tracking simulations were used to compute areas contributing recharge and travel times from recharge areas to selected public-supply wells. Model results indicate recharge from agricultural irrigation return flow and precipitation (about 89 percent of inflow) provides most of the ground-water inflow, whereas the majority of ground-water discharge is to pumping wells (about 78 percent of outflow). Particle-tracking results indicate areas contributing recharge to public-supply wells extend northwest because of the natural ground-water gradient from the northwest to the southeast across the study area. Particle-tracking simulations indicate most ground-water travel times from areas contributing recharge range from 20 to more than 100 years but that some ground water, especially that in the lower confined unit, originates at the upgradient model boundary instead of at the water table in the study area and has travel times of thousands of years.

Hydrogeology, Chemical Characteristics, and Transport Processes in the Zone of Contribution of a Public-Supply Well in York, Nebraska

In 2001, the U.S. Geological Survey, as part of the National Water Quality Assessment (NAWQA) Program, initiated a topical study of Transport of Anthropogenic and Natural Contaminants (TANC) to PSW (public-supply wells). Local-scale and regional-scale TANC study areas were delineated within selected NAWQA study units for intensive study of processes effecting transport of contaminants to PSWs. This report describes results from a local-scale TANC study area at York, Nebraska, within the High Plains aquifer, including the hydrogeology and geochemistry of a 108-square-kilometer study area that contains the zone of contribution to a PSW selected for study (study PSW), and describes factors controlling the transport of selected anthropogenic and natural contaminants to PSWs.

Assessing Sandhill Crane Roosting Habitat along the Platte River, Nebraska

Each spring approximately 500,000 sandhill cranes and some endangered whooping cranes use the Central Platte River Valley in Nebraska as a staging habitat during their migration north to breeding and nesting grounds in Canada, Alaska, and the Siberian Arctic. Over the last century changes in the flow of the river have altered the river channels and the distribution of roost sites. USGS researchers studied linkages between water flow, sediment supply, channel morphology, and preferred sites for crane roosting. These results are useful for estimating crane populations and for providing resource managers with techniques to understand crane habitats.
