Absorption Of Nutrients From Subsoil In Relation To Crop Yield, John W. Crist, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Investigations of the development of root systems of native and crop plants have been pursued for a number of years at the University of Nebraska. The gradual intensification of this work has led to a type of experimentation designed to discover the nature of the activities of roots at great depths in relation to absorption of water and nutrients. In the present investigation the effects of absorption of nutrients from deep levels upon quantity and quality of yield were determined. Studies on the amounts of water and nitrates removed by crops from various soil levels were begun in i919, but …

Range And Pasture Management, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Sampson's range and pasture management is an excellent example of the application of the principles of ecology to the solution of economic problems. In grazing experiments it is of equal importance to know what is happening to the stock and to the vegetation. This emphasizes the fact, which ecologists are coming more and more to recognize, that animals, both wild and domesticated, have a proper place in the environment and that they play an important role in modifying the vegetational development. This volume consists largely of first-hand information obtained by the author during fifteen years of intensive pasture investigations for …

Critique Of Influence Of Mineral Manures Upon The Mineral And Nitrogen Composition Of Plants, Dan Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Variation in quality of plants of the same species has been known to exist for a long time. The influences bringing about such variation have been studied only comparatively recently. Quantity production has been given the greatest amount of attention as a rule, the beneficial results from the use of manures being judged by the quantity of produce. Some plants, however, varied so widely in composition, and the variations were of such paramount importance, that the influences affecting quality began to receive some attention. Of this type of plants may be mentioned sugar-beets and tobacco. There was also the hope …

Circular No. 50 - Brooding And Feeding Chicks, Byron Alder

UAES Circulars

Raising baby chicks seems a comparatively simple matter to some, yet there are more failures in poultry-keeping due to inability to raise good, vigorous pullets than to any other one cause. The number of eggs produced, the size of the eggs (within certain limits), and the profit made from a flock of hens is often determined very largely by the success in brooding the chicks and developing the pullets into strong, vigorous hens. Many who try to raise chicks are not successful because they fail to realize that a baby chick is a "real baby". They cannot survive with careless …

Circular No. 49 - This Public Domain Of Ours, George Stewart

UAES Circulars

In Utah are somewhat more than fifty-two and a half million acres of land. Of this about five million acres are in farms, but only 1,371,000 acres, or 2.6 per cent, are irrigated. In addition there are about 344,000 acres under dry-farm culture, making a total of 1,715,000 acres of improved land. This leaves all of Utah's fifty-two and a half million acres, except about 3.5 per cent, to be utilized by some means other than crop-growing. There will be some addition of new lands not in farms and some development in unimproved farm lands, but when every development that …

Tuberculosis affects all species of domestic mammals although with different degrees of intensity and frequency. Cattle and swine furnish the greatest number of cases.

Bulletin 118 - Pigs And Pig Raising, P. G. Hampshire

Bulletins 1 - 2999

The importance of the development of pig-raising as one of the primary industries of Western Australia cannot be too greatly stressed.

In Western Australia we have a deficiency in production of bacon and hams equal nearly £200.00 per annum. When this exceedingly profitable market has been satisfied, export markets are geographically very favourable to Western Australia pig raisers as compared to the rest of Australia.

Circular No. 48 - Rural Credits In Utah, E. B. Brossard

UAES Circulars

The subject of rural credits is of interest to farmers, bankers, investors, and all others concerned about public welfare. This circular is written for the purpose of giving general information about agricultural credit conditions existing at the present time, with special reference to mortgage credit in Utah and the Federal Farm Loan System as now amended. The passage of the Federal Intermediate Credits Act, approved March 4, 1923 makes this an opportune time to check up on the situation.

Bulletin No. 186 - Irrigation Experiments With Sugar Beets, F. S. Harris, D. W. Pittman

UAES Bulletins

A previous bulletin of this station gives the results of an experiment on the irrigation of sugar-beets continuing for five years. Since this experiment was deemed of sufficient importance to merit our best attention and since the climatic conditions which largely determine what is the best irrigation practice may not for so short a period properly represent the average of the community, it was thought advisable to continue the experiment, with certain modifications, for an additional five years. This bulletin reports the results of these last 5-years' work together with such general conclusions as can be drawn from the entire …

Bulletin No. 187 - Irrigation Experiments With Potatoes, F. S. Harris, D. W. Pittman

UAES Bulletins

In a previous bulletin of this station are given the results of an experiment on different irrigation treatments of potatoes continued for five years. In view of the importance of the potato crop and of the importance of having it properly irrigated it was considered advisable to continue the experiment, with certain modifications based on experience, for a further period of five years. This total period of ten years should include most of the climatic variations which are common in this locality, and by eliminating the more unsatisfactory irrigation systems a closer approximation to the best system should be found. …

Bulletin No. 185 - The Influence Of Nitrogen In Soil On Azofication, J. E. Greaves, D. H. Nelson

UAES Bulletins

Many soils of the arid west have a rich active azofying flora. This is due in no small measure to their composition. They are high in calcium and magnesium carbonate and contain a good supply of available phosphorus and potassium but have a low nitrogen content. They are poor in organic carbon; hence, their native supply of energy is limited. It is well-known that a liberal supply of rapidly decaying organic matter is beneficial, and this is being supplied to some soils in the form of manures. This will increase the nitrogen content of the soil. What effect will this …

Bulletin No. 184 - A Farm-Management Study Of The Great Salt Lake Valley, George Stewart

UAES Bulletins

This survey had for its purpose the study of farm organization in Great Salt Lake Valley. It is hoped that some conclusions may have been reached as to how to improve farming conditions. The records were taken during the summer of 1915 and consequently represent the farm business for 1914. Ordinarily the period of time that has elapsed since the records were taken would be too long to justify their being published. In view of the fact, however, that the World War began in 1914 and that its effects on the prices of farm products lasted until 1921, it is …

A Study Of The Flowering And Fruiting Habits Of The Delicious Apple, Emery R. Ranker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the most disagreeable and at the same time the most unprofitable features of commercial apple production is the tendency of most apple varieties to "take a rest" every other year in order to regain the strength given to the production of a very heavy crop the previous year, and thus be able to repeat the process of heavy production the following year. This process is referred to as "off-year" or alternate bearing. Various causal relationships have been suggested , from time to time, by the different workers in the field but the suggestion now most generally accepted, and …

Soft Cheese Making, Susan Z. Wilder

Adequate Diet For The School Child, Susan Z. Wilder

SDSU Extension Circulars

Ease of digestion and adequacy in protein, minerals, and vitamins are absolutely essential for the school child. The results of mistakes in the feedings of school children are not seen as quickly as in the case of younger children. Mistakes in feeding at this age may result in serious diseases conditions later on. The adolescent child probably requires as much or more food than the adult because he is growing rapidly. The three food needs for both children and adults are those to supply building materials for repair and growth, fuel foods for heat and energy, and to take care …

Bulletin No. 183 - Water-Holding Capacity Of Irrigated Soils, Orson W. Israelsen, Frank L. West

UAES Bulletins

All information that will 'enable the irrigator to use water economically is valuable to arid-climate agriculture. In many arid-climate regions, including the western part of the United States, excessive waste of water occurs in the irrigation of highland porous soil areas, as a result of lack of information concerning the capacity of the soil to hold water. Following the waste of water on the uplands by excessive percolation through open soils, vast lowland areas are rendered partially or wholly nonproductive by water-logging. To illustrate, a gravelly bench soil four feet deep, if underlain by a coarse open gravel to a …

Bulletin No. 178 - The Irrigation Of Barley, F. S. Harris, D. W. Pittman

UAES Bulletins

The proper use of irrigation water is one of the most important problems of every comnunity and of every farmer in an irrigated district. The irrigation farmer has largely under his control one of the most important factors in determining the yield and quality of his crops and one over which all other farmers have little control at all. On the other hand, in an arid district there is generally less available irrigation water than is needed to give the optimum amount to all the land, or if one region receives an excess there is generally an accumulation of alkali …

Eggs, Mary A. Dolve

SDSU Extension Circulars

When we remember that an egg is store-up food material to be used for developing the young chick, we can naturally expect it to be a good food containing the various nutrients. Eggs are more nearly interchangeable with milk than any other food. Eggs are tissue building foods, being rich in protein and mineral matter. (Phosphorus, calcium, and iron.) On account of their richness in iron, they are one of the first foods added to the growing child’s diet.

Fruits And Vegetables : Budget, Salad And Greens, Mary A. Dolve

SDSU Extension Circulars

Fruits and vegetables have been wrongly considered by some as luxuries and relishes valuable principally for the pleasant variety they give to the diet. This conception may be largely due to the fact that they contain a large amount of water and a comparatively small amount of the so called nutrients. The fact that milk is the most perfect food, though it contains 87% water goes to show that the nature of the solids in any food rather than the quantity determines its actual food value. As a whole fruits and vegetables are more economical sources of protein and energy …

Circular No. 47 - Celery Culture For Utah, T. H. Abell

UAES Circulars

At one time practically all the celery consumed in Utah was shipped from California and eastern states. It was soon discovered, however, that celery could be raised in Utah, and as the population increased more and more acres were utilized in the production of this crop. Very little found its way to the outside markets, but what little did get out was well received because of its very high quality. Men who travel say that "Utah Celery" on the menu on trains and in hotels means the best there is in celery.

Within recent years several carloads have been shipped …

The Three Food Needs, Mary A. Dolve

SDSU Extension Circulars

All parts of the body, muscles, bones, nerves, blood, etc., must be supplied with material from which they can grow or make repairs. The bodies need for building and repair material is like that of an automobile. Materials are needed to build it in the first place, and after that there will be need of constant repairs. No good machine can be made without the right material, nor can it last long without repairs.

Bulletin No. 181 - Duty-Of-Water Investigations On Coal Creek, Utah, Arthur Fife

UAES Bulletins

Coal Creek flows from the west slope of the part of the Wasatch Mountain range which is located in the southeast part of Iron County, Utah. Its drainage area is almost 100 square miles.

Seasonal and daily stream-flow fluctuations are very pronounced. During the high water of spring the flow has reached more than 600 second-feet. At the time of high water, the daily fluctuations are the greatest. During the low water season in July and August, the flow has dropped as low as 12 second-feet since 1917, when accurate records were first kept; and, from the accounts of early …

Bulletin No. 182 - The Net Duty Of Water In Sevier Valley, Orson W. Israelsen, Luther M. Winsor

UAES Bulletins

The Sevier River is one of the most important sources of irrigation water in Utah. It rises in two main branches. The south fork rises in Kane County and flows almost due north to Junction in Piute County, where it joins the east fork, which rises partly in Garfield County and partly in Sevier County. The Garfield County branch of the east fork flows north, and the Sevier County Branch flows south to Coyote where the two tributaries join and flow westward into Junction. From Junction, the river flows northward past Marysvale, Sevier, Richfield, Salina, Gunnison, and Mills, where it …

The School Lunch Box, Mary A. Dolve

SDSU Extension Circulars

The cold lunch at its best is not the most desirable food for taking care of the food requirements of the child, and when it is to be repeated every day of the school year is very apt to become tiresome and monotonous. The feeling that anything will do for the lunch box is altogether too prevalent. The lack of time is the most common excuse for the poorly prepared lunch box. It does not take any more time to put up wholesome lunches in an attractive way, but it does take thought and an appreciation of what the boy …
