Kimberley Research Station Progress Report, 1964 : Soil Fertility And Plant Nutrition, D B. Parbery, R. Wetselaar

Journal of the Department of Agriculture, Western Australia, Series 4

BEFORE 1963, very little work, other than that described in Burvill's original report, had been done on the analysis of Ord soils, nor had their fertility status been clearly defined.

The Starling, John L. Long

Journal of the Department of Agriculture, Western Australia, Series 4

Despite their pretty colour and their song, starlings cannot be considered beneficial, especially in the fruit and grain-growing areas of W.A. where they are declared vermin.

MILLIONS of starlings inhabit the settled parts of eastern and south-eastern Australia, but so far they have not reached Western Australia.

Kimberley Research Station Progress Report, 1964 : Climate, Jan Jerzy Basinski, E. A. Fitzpatrick, W. R. Stern

Journal of the Department of Agriculture, Western Australia, Series 4

A review of recent research in climate, soils, tropical crops and pastures, weeds, insect pests and cattle husbandry at the Kimberley Research Station.

EXTENSIVE climatic data are recorded at the Station and analysed in relation to crop performance, irrigation requirements, and farm management practices.

Seed And Pasture Rates For New Dairy Pastures, F E. Ryan

Journal of the Department of Agriculture, Western Australia, Series 4

THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.

Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.

Wheat Quality Surveys In Western Australia. 2. Variation Between Seasons And Localities In The Production Of High And Low Protein Wheat, J A. Parish

Journal of the Department of Agriculture, Western Australia, Series 4

Although the protein content of West Australian f.a.q. wheat averages only 9.4 per cent., often substantial amounts of comparatively high protein wheat are contained in this mixture.

However the quantity varies widely from year to year and is obtained from widely scattered areas of the wheatbelt.

Sulfur Fertilizers For Alfalfa Production In Nebraska, R. L. Fox, A. D. Flowerday, F. W. Hosterman, H. F. Rhoades, R. A. Olson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

In order to elaborate all aspects of the sulfur problem in alfalfa production, a series of field, greenhouse and laboratory experiments was initiated to determine: 1. The influence of sulfur fertilization on the yield of alfalfa in Nebraska. 2. The influence of sulfur fertilization on the protein, vitamin A, and sulfur contents of alfalfa. 3. The sulfur supplying capacities of various soils under field and greenhouse conditions. 4. The sulfur content of precipitation at widely scattered points in Nebraska. 5. Soil properties associated with sulfur deficiency. 6. Optimum methods for estimating the sulfur status of soils by soil testing. The …

Phosphate Requirements Of Rice In The Ord River Valley, Rijn P J Van, A. L. Chapman

Journal of the Department of Agriculture, Western Australia, Series 4

A three-year experiment on the initial and maintenance phosphate requirements of wet-season rice was carried out at Kimberley Research Station between 1960 and 1963.

Application of 2 cwt. per acre superphosphate as the first application on new land, followed by annual application of 1J cwt. per acre is recommended.

The Development Of Irrigation In Nebraska, 1854–1910: A Descriptive Survey, Martin Evald Carlson

Department of History: Dissertations, Theses, and Student Research

Preface (excerpted)

The primary purpose of this study is tto trace the development of irrigation in Nebraska from the organization of the state as a territory in 1854 through the rest of the nineteenth century. This period covers the first four stages through which irrigation progressed: individualistic, corporate, district, and state. A brief discussion of the North Platte Project is included, however, in order to carry the story into the fifth and final stage--the development of irrigation with Federal aid, as provided for in the Reclamation Act of 1902.

The emphasis of this work is on the irrigation movement and …

The F.A.Q. Standard For 1962-63, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THE term f.a.q. refers to "fair average quality" as a standard for the sale of wheat -*- produced in Western Australia during any particular season.

The practice of using this standard developed after a standard sample of wheat grown in 1904 was obtained and declared to have a bushel weight of 62 lb.

A Progress Report On Commercial Cotton Growing On The Ord River Project, William John Toms

Journal of the Department of Agriculture, Western Australia, Series 4

The recommendations given in this article have been built up from the experience of the author in growing 200 acres of cotton in the Ord River area during the 1962-63 season for the Department of Agriculture, from findings made by Kimberley Research Station, and from discussions with the present farmers in the area.

When a new form of agriculture is introduced into a new area techniques and ideas change rapidly as farmers become acquainted with their new environment and the new crops. The recommendations will therefore require constant revision.

Applying Copper And Zinc Fertilizers To Cereals, H M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

Most light soils with a sandy or gravelly surface are likely to need copper and zinc; heavier clay or loamy soils mostly do not.

Frost Injury Of Wheat, S C. Chambers

Journal of the Department of Agriculture, Western Australia, Series 4

Late spring frosts commonly reduce yields and affect the quality of grain in many wheat crops- especially throughout the southern, eastern and north-eastern districts.

The damage is usually localised on individual farms, but occasionally widespread damage occurs in the south of the State.

Farming Without Fallow, H M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

UNDER the more intensive cropping rotations common in the early development of the cereal areas of Western Australia bare fallowing was a basic technique in cereal production.

By ploughing the land in July or August and keeping it bare of vegetation for nine or ten months, either by grazing or cultivation, a substantial beneficial effect on the subsequent crop could be expected.

Bare Patch And Poor Emergence Of Cereals. 3. Crusting Of The Soil Surface, S C. Chambers

Journal of the Department of Agriculture, Western Australia, Series 4

In some seasons extensive bare patches occur in cereal crops sown on the heavier wheat belt soils.

Experimental results from Beverley indicate that the poor emergence in some of these plantings may be due to crusting of the soil surface.

Working the surface with light harrows may destroy the crust and improve emergence.

Microorganisms And Soil Structure, T. M. Mccalla, F. A. Haskins

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Good stable soil structure is valuable for promoting the growth of plants and micro-organisms by permitting enhanced aeration and water penetration and by decreasing erosion under some conditions.

Micro-organisms influence water percolation through the soil. They may plug up soil pores with byproducts of growth and reduce water percolation. On the other hand, if a soil containing a large amount of microbial products is stirred and allowed to dry, then the percolation may be high.

Micro-organisms are involved in stabilizing soil structure by their products of decomposition and their cellular binding material, such as mycelia. Microorganisms differ greatly in …

Some Results With Nitrogen Fertiliser On Cereals At Esperance Plain Research Station, William John Toms

Journal of the Department of Agriculture, Western Australia, Series 4

ON newly-cleared land at Esperance Plain Research Station the use of sulphate of ammonia on cereals has proved profitable over a number of seasons.

The response to sulphate of ammonia varies markedly with the season.

The Development Of Western Australian Sand Plain Soils For Agriculture, Richard Philip Roberts, F. L. Shier

Journal of the Department of Agriculture, Western Australia, Series 4

IN a recently published economic survey of the Australian wheat growing industry, it was reported that nearly two-thirds of the farms surveyed in Western Australia were located on lateritic "sand plain."

As a random selection was made of the eighty farms that were visited it is reasonable to conclude that a similar proportion of all the State's wheat producing farms are on that type of country.

This constitutes a remarkable change from the earlier days of wheat belt settlement when the sand plain soils were regarded as virtually useless and by-passed for development.

It is the purpose of this article …

Kimberley Research Station : A Progress Report, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

INTEREST in the agricultural potential of the Kimberley region in Western Australia dates from its early exploration and settlement in the last century.

Several farming development schemes were considered for the area, but were never implemented.

This could be mainly attributable to lack of knowledge of agricultural potentialities, limitations of the local environment and ways of exploiting the local environment.

Up to the present the economy of the region is almost entirely based upon the extensive production of beef and to a lesser extent, wool.

Commercial Vegetable Growing In The Perth Metropolitan Region, L T. Jones

Journal of the Department of Agriculture, Western Australia, Series 4

MARKET gardening with sprinkler irrigation on deep sandy soils around Perth is really a commercial application of hydroponics or sand culture principles.

Provision of a continuous and adequate supply of nitrogen is the major problem. Peat swamps scattered among the sandy areas have higher natural fertility. However, their common problems are drainage, acidity ("sourness"), salt and various special soil deficiencies. Over-liming of acid swamps can cause new problems.

Granular Fertiliser, C R. Hale

Experimental Summaries - Plant Research

There is general agreement that granulation of fertilisers improves their physical characteristics with respect to handling, storage and distribution in the field. These physical advantages rather tan any established agronomic reason appear to be responsible for the increasing use of granular fertiliser.

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 …

Microorganisms And Soil Structure, T. M. Mccalla

Department of Agronomy and Horticulture: Faculty Publications

SUMMARY

Laboratory tests were made to determine the effectiveness of different compounds and microbial groups in increasing the stability of Peorian loess lumps against the action of falling water drops. The influence of these on percolation tests in the laboratory was also determined.

Many organic substances-dextrose, sucrose, starch, peptone, cullulose, and gum arabic-did not themselves contribute directly to soil-structure stability, though these substances do furnish energy material for soil microorganisms, which can convert them readily into either microbial tissue or decomposition products that increase soil-structure stability. Lignin, proteins, oils, fats, waxes, resin, and paraffin increased the stability of lumps of …

Leaflet No 1003 - The Salt Problem In The Wheat Belt, G. H. Burvill

Bulletins 1 - 2999

IN the wheat belt of Western Australian bare patches in farm paddocks are often seen. Many are bare, or almost bare, because of too much salt in the soil. The excess of salt prevents the germination of seeds, or kills living plants, because it causes the water supply for germination or growth to be cut off. This salt problem is so serious in places that single farms or groups of farms have been ruined; wheat growing on them has become unprofitable.

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.

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 …

The Effect Of Cultivation On Certain Chemical And Physical Properties Of Some South Dakota Soils, Oscar E. Olson

Electronic Theses and Dissertations

Soil Nutrient losses have followed closely in the paths of advancing frontiers in agriculture. Remedies for depletion as the result of overcropping were sought by George Washington, whose interest and investigation of soil nutrient losses probably represent the earliest attention given to land exploitation in the United States, which at the present time has become a problem of national concern. Soil losses have been attributed to a number of causes , among which are cropping, erosion, leaching, burning, and rapid oxidation of organic matter in the soil. Associated with soil nutrient losses, certain significant physical and chemical changes may occur …

Temperature And Atmospheric Humidity As Factors Influencing Seed Setting In Alfalfa, Lealand A. Clark

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years seed growers have thought that definite relationships existed between seed production and the weather. When this subject is approached there is little unity of opinion, even among neighboring seed growers. This lack of unity would indicate that growers generally are aware of some cause which affects seed setting, but they are not certain that any particular condition of the weather is the chief contributing factor. Scientific writers¹ on the subject are also confident that weather is probably one of the major factors influencing seed production.

Principles Of Irrigation Farming As Developed By American Field Experiments, Prabh Dyall Sikka

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Irrigation is "the artificial application of water to the soil for the purpose of getting large and steady crop yields". It is supplementary to rainfall and the quantity of water applied and the time of application, therefore, must be determined by the character of the rainfall. Irrigation is usually practiced in those regions which have low rainfall as natural precipitation at such places is insufficient to meet the full water requirements of crops.

Improvement Of Small Grains By Pure Line Selection, Dilworth Walker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present economic status of grain farming in the United States calls for adjustments in various ways. Legislation, such as price fixing, can do very little. Adjustment of acreage along with improved methods of marketing can do much. But improvement of the grains grown through breeding processes to increase the yields per acre and improve the milling quality, will render a service of permanent value, since all of the results appear in the profit column.

Bulletin 115 - The Value Of Windmills For Pumping Water In Western Australia, A. H. Scott

Bulletins 1 - 2999

It is surprising to note the dearth of up-to-date reliable information dealing with actual results of modern windmills, under working conditions, though literature on thousands of other subjects less important can usually be obtained.

In this bulletin there is presented a complete and accurate record of the amount of water pumped daily by a windmill, under actual working conditions, for a period of 14 months.
