Presentations by leading experts will address the broad concept of sustainable development, with a particular look at Arizona's experience. The focus will be …

Transitions In Masculinity And Hemingway's Developed "Code", Daniel Polk

Honors Theses

The "Hemingway Code" is much more than two words that fit nicely together for a scholar's usage; the words signify a much deeper championing of masculinity, almost a haunting presence. For Ernest Hemingway living life every day, every moment with its fullest masculine fervor, became an obsession, a never-ending quest to be at one with the attitude of never complaining, never crying out, panicking, thinking too much, or regretting. To live a manly life in a series of tactical victories, performed with steadfast ritualistic mannerisms, is to embody masculinity, and therefore the "Hemingway Code."

Buntine-West Wubin And West Maya Catchment Management Report, William Oldfield, Natalie Hunt

Natural resources published reports

Buntine West/Wubin land Conservation District was formed when a number of landholders wanted to extend and join on to some existing deep drains. At first the group concentrated on the deep drains with some farmers joining on anda project to connect the drains up througha naturally occurring saline area and to run the main drain into a salt lake system. Funding was attained for 50% of the project and farmers with drains paid for the rest. It was considered unfair for landowners whose land this drain went through to pay all the cost as it was not draining arable land. …

What Leading Alfalfa Growers Do To Produce Quality Hay, Jimmy C. Henning, Garry D. Lacefield, Buddy Sims

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is the highest quality forage legume crop grown in Kentucky and is the number one cash hay crop. Hay raised by Kentucky farmers has been recognized for its quality at local, state (state fair and Kentucky Alfalfa Conference), and national (American Forage and Grassland Council) hay contests. The testing records of the Kentucky Department of Agriculture also document the high quality alfalfa hay of Kentucky. However, little has been written about the farm practices used to produce high quality alfalfa hay in Kentucky. The current practices of top hay growers may be helpful in defining the options available to …

How To Make Your Alfalfa More Profitable, Clive Holland

Kentucky Alfalfa and Stored Forage Conference

As a perennial plant, alfalfa can be expected to continue to live and produce for an indefinite period of time. Why then do stands need to be replanted every few years? Is modern seed available today, weakened and unable to live up to the perennial label? What about yield? How does your stand measure up? Are you barely making the state average, or struggling to even meet this modest yield level?

The first harvest each spring can produce over 40% of the yield in a single growing season. Why is a stand slower growing in the spring than you would …

Role Of Alfalfa In Animal Diets, Jennifer L. Garrett

Kentucky Alfalfa and Stored Forage Conference

Alfalfa forage use has increased in all classes of livestock - dairy, beef, horses, sheep, and swine - during the last 40 years. The highest utilization of alfalfa by livestock is found in dairy cattle diets. Additionally, the use of alfalfa as a grazing crop has also undergone a considerable increase with the use of new grazing management techniques and the development of new grazing varieties.

Alfalfa's strength as a forage crop is its high nutritional value. Alfalfa is higher in protein, minerals, and net energy than grasses and small grains. High quality alfalfa also helps to promote intake, especially …

Saving Those Valuable Leaves During Haymaking, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Field dry hay needs to be reduced from near 80% moisture to 20% or less to prevent spoilage during storage. Drying hay to safe baling moistures often takes several days. Sources of loss during forage harvest include mechanical losses such as mowing, conditioning, chopping, raking, packaging and handling as well as respiration and leaching. The general relationship between forage moisture concentration at harvest and losses during the field and storage phases is shown in Figure 1. Harvest losses are greatest for very dry forage and are low for very wet material like direct cut silage. However, the latter is subject …

Alfalfa As A Grazing Crop: Progress Continues, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

This makes the third consecutive year that I have talked about "Alfalfa as a Grazing Crop". At our XIII Kentucky Alfalfa, I, along with five other speakers, discussed several aspects of grazing alfalfa and all agreed that the concept had tremendous potential.

This past year I reviewed some of the discussion of our XIII Conference and shared some of the activities going on in research and educational programs throughout the region. In addition, I announced the date for a National Alfalfa Grazing Conference to be held in Nashville, Tennessee. The Conference was held July 29 and was a big success. …

Control Of Johnsongrass And Other Weedy Grasses In Alfalfa, Jonathan D. Green

Kentucky Alfalfa and Stored Forage Conference

Johnsongrass is considered one of the major weed species that infests alfalfa in Kentucky. Other weedy grasses such as large crabgrass, foxtails, barnyard grass, and fall panicum can also interfere with alfalfa production. Low infestation levels of these grasses may not create significant concern, but high infestation levels can result in reduced yield, alfalfa hay quality, and/or shorten the life of the stand.

Opportunities For No-Till Alfalfa In Kentucky, Jimmy C. Henning, Garry D. Lacefield, Andy Anderson

Kentucky Alfalfa and Stored Forage Conference

There is a rising interest in the use of alfalfa in pastures, especially for dairy cattle, beef stockers and as supplemental summer grazing for cows with calves. Kentucky has the land resource to support 2 million acres of alfalfa without reducing acres in cultivated crops. Acres of alfalfa seeded for pasture use would be in addition to the 350,000 acres presently used primarily for hay. However, these additional acres are rolling and erodible and therefore alfalfa should be established by no-till methods.

Establishing Alfalfa Following Alfalfa: How Long Do We Wait?, Monroe Rasnake

Kentucky Alfalfa and Stored Forage Conference

It has long been recommended that alfalfa fields be rotated to another crop such as com for at least one growing season before reestablishing alfalfa. One reason for doing this is that insect and disease levels build up in the old alfalfa and this time is needed to allow them to die out. Another reason is that alfalfa plants have been shown to produce compounds that inhibit the germination and growth of new alfalfa seedlings. This is called autotoxicity or allelopathy.

Recently researchers from other states have indicated that it may not be necessary to have a full growing season …

Making Horticulture Sustainable, Bob Paulin, Neil Clifton Lantzke, Ian Mcpharlin, Murray Hegney

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

Sweet crunchy carrots, luscious strawberries at very reasonable prices, crisp green vegetables - these are just a few of the horticultural products that Western Australians take for granted and eat almost every day. But is their future availability guaranteed as population grows, suburbia spreads and environmental concern increases?

Storm : [Wind Erosion In The Great Southern], Dan Carter

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

On Thursday 11 May 1995, a low pressure system with central barometric pressure of 990 hPa formed of south-western Australia. This depression directed gale force winds over the South-West Land Division for some seven hours.

Dan Carter reports on the widespread damage to soils and property, and management practices that would have reduced the problem.

Land Management Report For The Kent River Catchment, Sue Kelly

Natural resources published reports

The Kent River Catchment is located in the South-West of Western Australia, approximately between latitudes 34° 15' and 35° 10' South and longitudes 116° 45" and 117° 50° East. The north-eastern boundary of the catchment stretches to the Albany Highway at Tenterden, and from there the catchment curves towards Rocky Gully before continuing to the South Coast (Figure 1.1.1). The catchment is located within the Shires of Cranbrook, Plantagenet and Denmark.

The Kent River Catchment is part of Basin 604, which is the Water Authority descriptor for the Kent, Bow and Kordabup River catchments collectively. Basin 604 has a total …

A Guide To Floodplain Cattle Fencing, Department Of Agriculture, Western Australia, Main Roads, Western Australia

Animal production and livestock published reports

A seminar and workshop was held at Fitzroy Crossing in October 1993 to address the consequences of flooding to landholders and communities.

Damage to flood plain fencing was identified as one of the major concerns to landholders.

An outcome from the workshop was the decision to draw on local knowledge and collate information on options for fence and floodgate designs.

This information was to be made available to land holders and other interested parties - hence this publication.

Miscellaneous Publication 39/94 - Horticulture On The Swan Coastal Plain - A Study Of Grower Concerns, Department Of Agriculture, Western Australia, Water Authority, Western Australia, Csiro, Australia

Horticulture published reports

This study reports on issues, concerns and desired actions expressed in 60 interviews with people directly involved in horticulture on the Swan Coastal Plain in the region between Gingin and Mandurah. I stress that in compiling this report every effort has been made to avoid biasing or changing the information provided by growers.

These interviews were conducted over ten days during April 1994.

The study also presents information on what is currently being done to address some of these concerns by the Department of Agriculture and the Water Authority of Western Australia as well as other agencies and organisations and …

Bulletin 4279 - Streamlining - An Environmentally Sustainable Drainage Network For The Swan Coastal Plain (Peel-Harvey Catchment), Garry Heady, Neil Guise

Bulletins 4000 -

Community Catchment Centre Pinjarra

A network of over 1400 kilometres of drains and modified natural waterways constructed by the Public Works Department criss-crosses the Peel-Harvey catchment. There are also over 3300 kilometres of minor drains and natural waterways in this same region.

The expansion of agriculture relied on this extensive drainage network, which was designed to ensure rapid drainage of the region. Unfortunately there was little regard to future environmental consequences.

Along with drainage water, these same drains now carry high loads of silt and nutrients. Many of the drains are also degraded and require expensive maintenance annually.

Arkansas Rice Research Studies 1993, B. R. Wells

Arkansas Agricultural Experiment Station Research Series

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for longterm recommendations. Several research reports in this publication dealing with soU fertility also appear in Arkansas Soil Fertility Studies 1993, Arkansas Agricultural Experiment Station Research Series 436. This duplication is the result of the overlap in research coverage between the two series and our effort to inform Arkansas rice producers of all the research being conducted with funds from the rice check-off.

Discussion And Measurement Of Soil Erosion In Iceland, Kimberly Jane Richardson

Undergraduate Honors Capstone Projects

Soil erosion has occurred since the beginning of time. It is a natural process, but one that has been increasing at an alarming rate. Once soil is eroded--whether it is blown out to sea or washed down a river to sedimentize a lake--it is lost. It is almost impossible to reestablish similar soil components and characteristics in a given system. Since soil and vegetation reestablishment is expensive, the prevention of soil erosion by controlling its causes has become the most cost-effective reclamation effort.

After spending six months in Iceland, I wrote this paper on the unique erosion problems facing that …

Bulletin 4283 - Nitrogen Fertilisers For Cereal Production, M. G. Mason

Bulletins 4000 -

Because fertiliser prices are high, it is important to understand what affects the response to fertilisers by crops.

Among the many factors influencing crop response to nitrogen applications, the most important are the season, soil type, paddock history, time of application and source of nitrogen. Before deciding whether to use nitrogen on a cereal crop, which source to use and at what rate, you need some understanding of how these factors work.

Greatest responses to nitrogen fertilisers can be expected in areas with a relatively long growing season. In such areas light soils with a low nitrogen status give the …

Miscellaneous Publication 10/94 - The Climate And Soils Of South-Western Australia In Relation To Vine Growing, J. S. Gladstones

Viticulture research reports

The vine industry in Western Australia is at present located mainly in the Swan Valley, some 15 miles inland from Perth. It produces currants for export, wine grapes, and table grapes for both local and export markets, in approximately that order of importance.

Climatically, the Swan Valley is well suited to vine fruit production. With an annual rainfall of about 34 inches, it has a mild, wet, almost frost-free winter, and a warm, dry summer. Olmo (1956) concluded that the Swan was especially well suited to the production of currants, table grapes and sweet dessert wines. However, he considered that …

Marketing Quality Alfalfa Hay, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa hay is a potentially marketable-profitable product if--if quality is satisfactory to meet buyer's needs, if it is packaged such that it meets buyer's feeding program and can be transported efficiently, if in sufficient quantity, if storage site is accessible by truck or trailer, and if it is competitively priced. Meeting these minimum criteria only means the hay is potentially marketable; only after it has been sold does it become potentially profitable.

Producing Quality Alfalfa Hay, Jimmy C. Henning, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Hay is one of the most versatile of stored forages in that (1) it can be kept for long periods of time with little loss of nutrients if protected from weather; (2) a large number of crops can be successfully used for hay production; (3) it can be produced and fed in small or large amounts; (4) it can be harvested, stored and fed by hand or the production and feeding can be completely mechanized; and (5) hay can supply most nutrients needed by many classes of livestock. Hay is, therefore, the most commonly used stored feed on most farms. …

Harvesting Hay For High Yield And Quality — More On Bale Ventilators And Other Harvest Aids, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

In some areas of the country, producers store a substantial portion of their forage for winter feeding as silage or haylage. However, hay remains the most popular storage method for forage. Hay stores well for long periods and is better suited to cash sale and transportation than silage. Mechanical conditioning, which gained acceptance during the 1950's is probably still the greatest single change in hay harvesting and storage technology during this century. However, a number of other noteworthy changes and innovations have occurred in recent years which have helped to reduce the extent of losses during hay harvesting and storage. …

Role In Alfalfa In Livestock Feeding Programs In Kentucky, Donna M. Amaral-Phillips

Kentucky Alfalfa and Stored Forage Conference

Alfalfa, the "Queen of the Forage Crops", is a highly versatile forage crop which can be grazed directly by livestock or harvested as hay or silage. With the development of new alfalfa varieties, increased pest and weed control, and increased demand from livestock owners, the amount of alfalfa fed to livestock will increase. As with any forage crop, proper harvest and feeding management is necessary to reap the benefits.

Fencing For Optimum Grazing, Larry W. Turner

Kentucky Alfalfa and Stored Forage Conference

Controlled or rotational grazing can result in better utilization of forage resources. By better forage management through controlled grazing, producers may increase profitability of cattle/forage systems. To effectively develop a controlled grazing system, however, fencing must be used to subdivide the pasture into sub-fields or paddocks. The animals may then be rotated among the paddocks to optimize forage and beef or dairy production from the system. Alfalfa grazing can play an important part in such a system.

Planning the "best", or optimum, fencing strategy should be done with the overall goal in mind of improving profitability. Key factors that describe …

Grazing Alfalfa — Momentum Continues, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

In my presentation at our XIII Kentucky Alfalfa Conference held here last year, I stated. that interest in grazing alfalfa was at an all time high. Five other speakers followed me on the program with presentations about alfalfa grazing. Steve Osborne discussed alfalfa grazing trials in Monroe County. Ken Johnson talked about the Do's and Dont's in Alfalfa Grazing. Dr. Roy Burris talked about alfalfa grazing from a state perspective and Mr. Warren Thompson discussed the topic from a national perspective. Professor Joe Bums concluded the grazing portion of the program with grazing alfalfa experiences in Tennessee.
