Propagule Dispersal Among Forest Islands In Southeastern South Dakota, J. Warren Ranney, W. Carter Johnson

United States Department of Energy: Publications

The study of seed dispersal between the widely separated forest patches (forest islands) of the eastern Great Plains can contribute to understanding effects of deforestation in the more complex forest island landscapes of the eastern United States. In the East, there is growing concern that the dissection of regional forests and the creation of small forest islands surrounded by non-forest uses (e.g., agriculture) may be affecting plant species richness and developmental patterns of vegetation (Levenson 1976), as has already been noted in the tropics (Gomezpompa et al. 1972). Curtis (1956) showed that the presettlement forest area in a portion of …

Nutrient And Energy Composition Of Beef Cattle Feedlot Waste Fractions, C. B. Gilbertson, J. A. Nienaber, J. R. Ellis, T. M. Mccalla, T. J. Klopfenstein, S. D. Farlin

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This bulletin describes nutrient and energy composition of beef cattle waste fractions as a function of the ration roughage level and type of feedlot. Results can be used to plan engineering system approaches and research to develop handling and processing equipment necessary for recovery of the most valuable portion of waste.

Missouri River Hydrology (Streamflow And Temperature) – Sioux City, Iowa To Rulo, Nebraska, David L. Schreiber

United States Department of Energy: Publications

In any plan for the development of water and land resources, hydrology must be a basic consideration. Because of the Missouri River Basin's large size and the many associated variations in hydrologic characteristics, hydrology is of special significance.
The Missouri River drains an area of approximately 530,000 square miles, and it is the longest river in the United States (2,315 miles). The source of the Missouri River is the headwaters of the Red Rock River in Montana, and the mouth is at the Mississippi River near St. Louis, Missouri. Part or all of 10 states and 9,700 square miles in …

The Uranyl Nitrate-Water System Above 60°, W. L. Marshall, Jr., J. S. Gill, C. H. Secoy

United States Department of Energy: Publications

Although there are some data in the literature for the solubility of uranyl nitrate in water, the discrepancy of these data indicated the necessity for a check on the measurements. We have measured the solubility from the incongruent melting point of the hexahydrate at about 60° to the melting point of the dihydrate at 184°. Our results show a lower solubility than that given in most of the earlier data and also indicate an incongruent melting point for the trihydrate rather than the congruent point inferred in some of the previous work. The system is thermally stable up to the …

Aircraft In Agriculture, N. E. Shafer, J. D. Furrer, J. W. Lomax

Nebraska Agricultural Experiment Station: Historical Circulars

Airplanes were first used in agriculture shortly after the close of World War I. They proved valuable for locating mosquito breeding areas, for forest fire patrol work, as an aid in locating outlaw cotton fields in the campaign against pink bollworm, and for surveying damage caused in large forested areas by the spruce budworm.

Nebraska Farm Building Data For South-Central Counties Taken From U.S. Census, R. M. Loper

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The Material given on the following pages was selected from United States Census data for the years indicated.

It has been arranged to permit analysis and comparison of building trends since 1900, both in the state and in individuals counties. Such a study often reveals areas in which effective educational programs could be developed and indicates the phases of such programs which are needed most.

Unfortunately, complete 1945 figures are not available yet, but space has been left for them so that they may be added when released by the Census Bureau.

Nebraska Farm Building Data For North-East Counties Taken From U.S. Census, R. M. Loper

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Fluctuation in the number of farms since the start of the century reflects economic trends, drouth effects and the results of increasing mechanization, particularly since 1935.

The 1945 figures also show the influence of land taken out of production for use as air bases, ordnance plants and ammuition depots. No doubt some of this will be returned eventually to agricultural uses. Since the buildings were removed from this land during the war some new sets probably. will be constructed when individual ownership is obtained again. Such activities present excellent opportunities for developing farmsteads efficiently and attractively arranged; buildings designed to …

Adjusting Planters And Listers For Sorghums, L. W. Hurlbut

Nebraska Agricultural Experiment Station: Historical Circulars

It is the purpose of this circular to present data and suggestions that will aid the farmer in attaining greater success in the planting of sorghum. It has been prepared primarily for the machine operator; and, although it is not a complete discussion of planters and listers, it contains highly practical suggestions regarding the adjustment of the corn planter and lister for sorghum seed.

Fitting The Mechanical Refrigerator Into The Home, E. B. Lewis, M. P. Brunig

Nebraska Agricultural Experiment Station: Historical Circulars

Within the last five years the mechanical refrigerator has become a popular piece of household equipment. Its year-round use has caused architects and others interested in planning for the convenience of the housewife to recommend placing the new cabinet in kitchens and other convenient places, with little thought about the effect on the operation of the refrigerator. The purpose of this publication is to point out some of the conditions under which the refrigerator has been expected to operate successfully, and some of the effects of these conditions upon the operation of the machine.

The Use Of A Small Electric Motor In Silo Filling, E. E. Brackett, E. B. Lewis

Nebraska Agricultural Experiment Station: Historical Circulars

Filling a silo 30 feet or more in height with a motor as small as five horsepower has been looked upon in general by Nebraska farmers as an impractical, if not impossible, procedure. The practice is not unheard of in other states, and certainly the possibility of avoiding the large tractor-driven cutters and the large crews will be welcomed by those who have available service from power lines.

The Nebraska Tractor Law And Rules For Official Tractor Tests, O. W. Sjogren, E. E. Brackett, C. W. Smith, F. R. Nohavec

Nebraska Agricultural Experiment Station: Historical Circulars

The Nebraska Tractor Law, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of improved types of tractors and to contribute to a more successful use of the tractor for farming. It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public.

The Nebraska Tractor Law And Rules For Official Tractor Tests, L. W. Chase, E. E. Brackett, O. W. Sjogren, C. K. Shedd

Nebraska Agricultural Experiment Station: Historical Circulars

The Nebraska Tractor Law, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of improved types of tractors and to contribute to a more successful use of the tractor for farming. It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public. These tests will give reliable information on the power, capacity and fuel consumption of each tractor and also some information on endurance. The …

Measuring Silage And Capacity Of Silos, L. W. Chase

Nebraska Agricultural Experiment Station: Historical Circulars

The condition of the corn at filling time, the rate of filling, and the length of time settling has taken place before measuring the depth of the silage, all tend to cause variations in the weight per cubic foot of the silage and in the tonnage that can be placed in a silo. The greatest variation comes when very green corn or very ripe corn is used, and because of this it is possible that a cubic foot of green silage, which may weigh fifty pounds, holds no more dry matter than a cubic foot of overripe silage which weighs …
