Vegetative Filter Strip Removal Of Metals In Runoff From Poultry Litter-Amended Fescuegrass Plots, Dwayne R. Edwards, P. A. Moore Jr., Tommy C. Daniel, Puneet Srivastava, D. J. Nichols Jan 1997

Vegetative Filter Strip Removal Of Metals In Runoff From Poultry Litter-Amended Fescuegrass Plots, Dwayne R. Edwards, P. A. Moore Jr., Tommy C. Daniel, Puneet Srivastava, D. J. Nichols

Biosystems and Agricultural Engineering Faculty Publications

Runoff from land areas amended with poultry (Gallus gallus domesticus) manure can contain elevated concentrations of metals such as Cu, Fe, and Zn. Vegetative filter strips (VFS) can reduce runoff concentrations of animal manure components, but reported studies have typically focused on nutrients and solids rather than metals. This experiment assessed the impact of VFS length (0 to 12 m) on concentrations and mass losses of Cu, Fe, K, Na, Ni, and Zn in runoff from fescuegrass (Festuca arundinacea Schreb.) plots (1.5 m wide × 6 and 12 m long) treated with poultry litter. The runoff was produced from simulated …

Achievements In Wool 1997, Agriculture Western Australia

Animal production and livestock published reports

The Wool Strategy Group, which I initiated in 1993, and Agriculture Western Australia's Wool Program are strategic partners working together with industry to develop and market this State's wool industry.

Wool is Western Australia's second most important agricultural industry, with a current export value of $643 million. It has the potential to return to a billion dollar industry in the next five years and the industry needs to be strongly focused on producing what the market requires to take advantage of this.

The Wool Strategy Group, led by Chairman Mr Philip Gardiner, and the Wool Program, have established an international …


Bovine Respiratory Disease, Clell Bagley Jan 1997

Bovine Respiratory Disease, Clell Bagley

All Current Publications

Disease of the respiratory tract is a major problem for cattle and it continues to cause serious economic losses for producers. Bovine respiratory disease (BRD) causes increased death losses as well as medication costs, labor, and lost production. Many different infectious agents may cause similar clinical signs. Multiple agents are often involved in the development of BRD.


Molecular And Functional Characterization Of A Novel Low-Affinity Cation Transporter (Lct1) In Higher Plants, Daniel P. Schachtman, Raman Kumar, Julian I. Schroeder, Ellen L. Marsh Jan 1997

Molecular And Functional Characterization Of A Novel Low-Affinity Cation Transporter (Lct1) In Higher Plants, Daniel P. Schachtman, Raman Kumar, Julian I. Schroeder, Ellen L. Marsh

Department of Agronomy and Horticulture: Faculty Publications

The transport of cations across membranes in higher plants plays an essential role in many physiological processes including mineral nutrition, cell expansion, and the transduction of environmental signals. In higher plants the coordinated expression of transport mechanisms is essential for specialized cellular processes and for adaptation to variable environmental conditions. To understand the molecular basis of cation transport in plant roots, a Triticum aestivum cDNA library was used to complement a yeast mutant deficient in potassium (K+) uptake. Two genes were cloned that complemented the mutant: HKT1 and a novel cDNA described in this report encoding a cation …

The Impact Of Permaculture On The Above-Ground Mesofaunal Communities In The Perth Metropolitan Area, Ruth C. D'Sanges Jan 1997

The Impact Of Permaculture On The Above-Ground Mesofaunal Communities In The Perth Metropolitan Area, Ruth C. D'Sanges

Theses : Honours

Conventional agricultural practices (tillage, extensive application of synthetic fertilisers and biocides) exert substantial disturbance on soil ecosystems, consequently causing severe land degradation through loss of soil organic matter. These practices also place significant pressure on the soil inhabitants. However, permaculture systems practice non-tillage and extensive mulching. These non-tillage practices reduce the amount of perturbation on the litter invertebrates and encourage their abundances. The aims of this study were to describe the above-ground mesofaunal communities in the mulch layer of selected urban permaculture systems in the Perth Metropolitan area. This included determining the faunal abundance and diversity. Four permaculture sites were …


Diagnosis Of Livestock Production In Three Communities (La Inmaculada, Tunshi San Miguel, And Ela Guano) Using The Chambo Irrigation System - Guano, Egresado José Orozco Cruz Jan 1997

Diagnosis Of Livestock Production In Three Communities (La Inmaculada, Tunshi San Miguel, And Ela Guano) Using The Chambo Irrigation System - Guano, Egresado José Orozco Cruz

Theses and Dissertations

The purpose of this research was to implement a stratifying sampling system in the communities of La Inmaculada, Tunshi San Miguel, and Ela Guano, part of the Chambo-Guano irrigation system. The domesticated animal population in these communities consisted of cattle, sheep, swine, guinea pigs, and poultry. The animal feed used in these communities included alfalfa, grass, corn stalks, banana, weeds, kitchen residue, hulk, hard and soft corn, barley, wheat and other feed preparations. In general, animal management in these communities is technically deficient and most animals exhibited diseases that are controllable by veterinarians. Study recommendations to improve conditions for rural …


Study Of Livestock Production Levels In Three Communities Near The City Of Riobamba, Raul Rolando Nuñez Lopez Jan 1997

Study Of Livestock Production Levels In Three Communities Near The City Of Riobamba, Raul Rolando Nuñez Lopez

Theses and Dissertations

This study was done by administering household surveys to 50% of the families in the three communities. Families were selected through stratified random sampling. This allowed us to determine how much families are exploiting species that have a significant level of production as well as whether they use them for a commercial activity or subsistence. With regard to cows, 60.40 ± 4.72% of families use them. Each family has an average of 1.68 ± 0.21 cows. Productive cows make up 36.9% of the above percentage, which is a majority. The measured rate of production was 6.48 ± 0.25 L/cow/day. Overall, …

International Market Opportunities For Faba Beans, Andrew Quinn, Malcolm Sedgwick Jan 1997

International Market Opportunities For Faba Beans, Andrew Quinn, Malcolm Sedgwick

Farm Systems and Economics published reports

Western Australian faba bean production is growing and export volumes are increasing. In contrast, production is declining in many of the world's traditional faba bean regions. World trade, however, is growing.

China dominates the world export market and is growing rapidly as an exporter. The UK and Australia are the second and third largest exporters respectively.

As Western Australian production increases, the State will increasingly play an important role in Australia's ability to supply faba beans into markets looking tor quality and stable supply.

Saudi Arabia has emerged as the State's largest export market. The State is well located to …


Resource Management Decision Support Tools - Brief Model Descriptions, Campbell White & Associates Pty Ltd Jan 1997

Resource Management Decision Support Tools - Brief Model Descriptions, Campbell White & Associates Pty Ltd

Farm Systems and Economics published reports

During the past 10 years, a number of financial models have been developed within Agriculture Western Australia to assist decision making in resource management. Various approaches have been taken including whole farm, development and partial budgets.

Natural resource managers within Agriculture Western Australia, have identified a need to preserve these decision support systems in a central library. The models should be readily accessible to new staff, and the library should provide an 'engine' through which the models can be promoted, and information relating their application distributed. Recent technology such as the development and mainstream adoption of the World Wide Web …


Notes: Forage Yield, Quality, And Fertility Of Sorghum X Sudan Grass Hybrids In A1 And A3 Cytoplasm, Jeffrey F. Pedersen, J. J. Toy Jan 1997

Notes: Forage Yield, Quality, And Fertility Of Sorghum X Sudan Grass Hybrids In A1 And A3 Cytoplasm, Jeffrey F. Pedersen, J. J. Toy

Department of Agronomy and Horticulture: Faculty Publications

Currently, no information is available comparing the agronomic performance of A1 and A3 cytoplasms in sorghum x sudangrass [Sorghumbi color (L.) Moench] hybrids. The objectives of this study were to compare the effects of A1 and A3 cytoplasm on the maturity, fertility, height, forage yield, and forage quality of sorghum × sudangrass hybrids. In 1989, pollen from a bulk of eight sudangrass populations was used to pollinate four sorghum lines that had been male-sterilized in both A1 and A3 cytoplasm. Hybrids were grown at the Univ. of Nebraska Field Laboratory Ithaca, NE, in 1990 and 1991, in a split-plot …
