Natural resources published reports

Kununurra Region

3rd edition

A small experimental farm was first established on the Ord River in 1941. This farm was relocated in 1945 to what is now known as the Frank Wise Institute of Tropical Agriculture.

The first stage of the Irrigation Scheme which included the Diversion dam was completed by 1963 and by 1966, 31 irrigated farms had been established.

In 1967 the second stage was commenced and by 1972 the main dam had been completed.

Cotton was the major crop until 1974. In the wet season of that year 3642 hectares was devoted to cotton. Various crops such …

Organic Matter Budgets And Models For Four Plant Communities In The Great Dismal Swamp, J. Patrick Megonigal Apr 1986

Organic Matter Budgets And Models For Four Plant Communities In The Great Dismal Swamp, J. Patrick Megonigal

Biological Sciences Theses & Dissertations

Budgets and models of organic matter dynamics were developed for one mesic and three seasonally flooded plant communities in the Dismal Swamp. Components included aboveground parts, belowground parts, litter and soil organic matter (SOM).

Net primary- production was significantly greater on them flooded sites. Comparisons show that the Dismal Swamp is highly productive despite relatively low nutrient inputs.

Budget calculations showed that over 65% of the total input to SOM comes from roots. Leaves contributed about 70% of the aboveground inputs.

The model predicted that species composition, aboveground biomass and turnover rates on the cedar site will become quite similar …

Development And Validation Of A Dynamic Model Of Growth And Quality For Cool Season Grasses, W. F. Brown, Lowell E. Moser, Terry J. Klopfenstein Mar 1986

Development And Validation Of A Dynamic Model Of Growth And Quality For Cool Season Grasses, W. F. Brown, Lowell E. Moser, Terry J. Klopfenstein

Department of Agronomy and Horticulture: Faculty Publications

A daily time step model simulating growth and quality of cool season grasses was developed and validated for smooth brome (Bromus inermis Leyss.) under varying environmental and management conditions. Growth predictions are based upon genetic potential, environmental temperature, leaf area, soil moisture, and nitrogen fertilization rate. Daily potential growth rate is a composite of two functions—one relating grass species maximum growth rate to minimum, optimum, and maximum temperatures for plant growth, and another relating daily minimum and maximum air temperatures to time. Multipliers are developed for available leaf area, moisture, and nitrogen, and the minimum of these values modifies …

Marketing Kentucky Hay, J. Kenneth Evans Feb 1986

Marketing Kentucky Hay, J. Kenneth Evans

Kentucky Alfalfa and Stored Forage Conference

That more income is needed by Kentucky farmers is a well established and accepted fact. Although, the tobacco program appears to be yet viable, we have long needed to supplement the tobacco income with income from the remainder of the farm. I think this audience is also well aware of the potential· for producing hay in Kentucky, particularly alfalfa. Estimates in the University of Kentucky potential study indicate that we could have in this state two million acres of alfalfa with a projected potential income of a billion dollars a year generated for our farmers.

This potential income should not …


Optimum Utilization Of Alfalfa In Horses, Stephen G. Jackson Feb 1986

Optimum Utilization Of Alfalfa In Horses, Stephen G. Jackson

Kentucky Alfalfa and Stored Forage Conference

When considering forage utilization in horses one must consider principally two factors; 1) forage quality and 2) the relationship between voluntary intake of a forage and a particular class of horses nutrient needs.


Optimum Utilization Of Alfalfa In Sheep Rations, G. L.M. Chappell Feb 1986

Optimum Utilization Of Alfalfa In Sheep Rations, G. L.M. Chappell

Kentucky Alfalfa and Stored Forage Conference

The unique qualities of alfalfa as a forage afford the progressive sheep producer many opportunities to develop efficient sheep feeding programs. As a grazed sward, as hay or silage, alfalfa can be utilized in a variety of ways. The following points should be considered in developing programs using alfalfa.


Maximizing Alfalfa Hay In Beef Feeding Programs, W. Roy Burris, Garry D. Lacefield Feb 1986

Maximizing Alfalfa Hay In Beef Feeding Programs, W. Roy Burris, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Beef cattle comprise the largest group of forage and hay users in Kentucky. Because of their ability to utilize large amounts of low quality roughage, they are sometimes relegated to that role exclusively. There are many instances in beef production when alfalfa hay can be utilized because of its high protein content. The value of alfalfa hay in a beef operation can be estimated by the protein and energy that it furnishes.


Maximizing Alfalfa In Dairy Feeding Programs, Dan O. Riddell Feb 1986

Maximizing Alfalfa In Dairy Feeding Programs, Dan O. Riddell

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is an excellent feed for dairy cows. When used properly, alfalfa can help cut cost of production and increase level of production. However, like everything else, the feeding of alfalfa needs to be managed to maximize efficient production. There are three key steps involved in maximizing alfalfa in a dairy feeding program. These are:

  1. harvest alfalfa at the proper stage of maturity
  2. know what the alfalfa contains and feed accordingly
  3. get the alfalfa to the cows that need it.


Hay Quality Evaluation, William C. Templeton Jr. Feb 1986

Reducing Hay Losses — From Standing Crop Through Storage, Michael Collins Feb 1986

Reducing Hay Losses — From Standing Crop Through Storage, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Alfalfa management for maximum economic productivity is quite complex. Many factors ranging from cultivar selection and establishment to storage and feeding must be considered. In some cases these factors, yield and quality of a particular cutting of forage for example, are negatively correlated. Following good establishment of an adapted cultivar, cutting management has important effects on forage yield, forage quality, stand persistence, weed encroachment and other important responses. Maturity stage at the time of cutting greatly affects quality. After cutting, hay curing, packaging and storage conditions also affect quality. Clearly, in order to achieve the optimum combination of yield and …

No-Till Alfalfa Establishment, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

The topic ''No-till Alfalfa" was discussed at the V Annual Alfalfa Conference this past February in Elizabethtown. At that conference, we reported results of demonstrations that had been conducted along with preliminary results of some of the research underway. In the presentation today, I would like to review some of the opportunities for no-till alfalfa and discuss some additional research results.


Herbicides For Alfalfa Weed Control, William W. Witt Feb 1986

Herbicides For Alfalfa Weed Control, William W. Witt

Kentucky Alfalfa and Stored Forage Conference

Numerous herbicides are available for controlling weeds in pure or mixed stands of alfalfa. In addition, these herbicides can be applied at different times and stages of alfalfa growth -from prior to planting to actively growing alfalfa to dormant applications during the winter. To be confident of achieving the desired weed control, it is important to apply alfalfa herbicides at the proper growth stage and rate.

The following tables contain information pertinent to proper utilization of the herbicides to obtain maximum weed control.

Grazing And Management Of Saltland Shrubs, C V. Malcolm, J. E. Pol Jan 1986

Grazing And Management Of Saltland Shrubs, C V. Malcolm, J. E. Pol

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

areas of bare saltland on farms need not be unproductive etesores. Many Western Australian farmers are now successfully growing salt-tolerant or halophytic shrubs such as bluebush (Maireana brevifolia), saltbushes (Atriplex spp.) and samphires (Halosarcia spp.) on these areas.

Department of agriculture trials and farmers' experience indicate that if saltland is planted with recommended shrubs, it can provide two months' valuable grazing for sheep during autumn and early winter, a time when paddock feed is scarce. Research by the Department has also identified a range of salt-tolerant shrubs suited to the various types of saltland.
