Profiting From Adversity - Meeting The Challenge Of Salinity Through New Industry Development, Andrew Quinn, Tamara Law, Peter Rowe Nov 2000

Profiting From Adversity - Meeting The Challenge Of Salinity Through New Industry Development, Andrew Quinn, Tamara Law, Peter Rowe

Natural resources published reports

Salinity in the Wheatbelt of Western Australia is one of the most significant challenges facing the State's agricultural sector.

Efforts to manage the increasing effect of salt influenced and threatened farming land requires not only the implementation of new farming systems, but a new way of thinking and attitude to production more in tune with environmental and technological limitations.

While past environment lobby pressures have significantly focused on other production activities such as mining and forestry, the future is likely to see increased community interest in agricultural production systems.

Consumers World wide are becoming more environmentally sensitive, with global media …

Degradation In The Brockman River And Ellen Brook Catchments, Western Australia, Brian Lloyd

Natural resources published reports

An eight day survey of degradation in the Ellen Brook and Brockman River catchments revealed several areas of concern. Key concerns are:

Erosion and sedimentation

Various forms of erosion were observed during the survey that would cumulatively have an effect on the quality of both the Ellen Brook and the Brockman Rivers, and ultimately the Swan River. Erosion resulted from many situations including landholder management, subdivision design and infrastructure maintenance. Raising awareness as to consequences of erosion and sedimentation, along with remedial techniques and best management practices is recommended for the various levels of stakeholders.

Effects Of Elevated Atmospheric Co2 On Root Growth, Turnover And Decomposition In A Scrub Oak Ecosystem, John Joseph Dilustro Jul 2000

Effects Of Elevated Atmospheric Co2 On Root Growth, Turnover And Decomposition In A Scrub Oak Ecosystem, John Joseph Dilustro

Biological Sciences Theses & Dissertations

Atmospheric carbon dioxide levels are increasing and predicted to double this century. The implications of this rise on vegetation structure and function are not well understood. Measurement of root growth response to elevated atmospheric carbon dioxide is critical to understanding soil carbon input. I investigated the effects of elevated carbon dioxide on fine root growth and decomposition using open top chambers with both ambient and elevated (700 PPM) CO2 treatments in an oak-palmetto scrub ecosystem at Kennedy Space Center, Florida. Minirhizotron tubes were installed in each elevated and control chamber to allow observation of roots. Each tube was sampled …

Solute Transport As Related To Soil Structure In Unsaturated Intact Soil Blocks, L. Bejat, E. Perfect, V. L. Quisenberry, Mark S. Coyne, G. R. Haszler

Plant and Soil Sciences Faculty Publications

Concern about soil and groundwater pollution has resulted in numerous studies focused on solute transport. The objectives of our study were to investigate the effect of soil type and land-use management on solute movement. Transport of water and Cl− were measured through intact blocks of Maury (fine, mixed, semiactive, mesic Typic Paleudalf) and Cecil (fine, kaolinitic, thermic Typic Kanhapludult) soils, under steady-state, unsaturated flow conditions. Three replicate blocks for the Maury soil and two replicate blocks for the Cecil soil were studied per land-use treatment. The land-use treatments were conventional-till corn (Zea mays L.) production and long-term grass …

Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel

Environmental Science and Management Faculty Publications and Presentations

We reexamined geographic factors explaining the number of plant species on islands in the Galápagos Archipelago. We hypothesized that plant species richness (S) was related to the number of source pools and that plant species dispersal preferentially followed direct, oceanic pathways. To test different dispersal pathways from multiple source pools, the total number of islands within a given dispersal radius (i) was posed as the sum of the number of line-of-sight islands (Ci) and of the number of islands without line-of sight connection (Bi). In partial regression analyses, controlling for nearest island area (A2) …

Changes In Alfalfa Breeding — Where Is Alfalfa Headed?, Becky Greenwald Feb 2000

Changes In Alfalfa Breeding — Where Is Alfalfa Headed?, Becky Greenwald

Kentucky Alfalfa and Stored Forage Conference

Alfalfa didn't earn the title "Queen of the Forages" just because of its good looks on rolling hills or sweet smell at harvest. Alfalfa was first described nearly 2,500 years ago, in 490 B.C in the desert regions of what is now Iran. From the Middle East, alfalfa was taken into Europe and South America by invading armies, explorers, and missionaries.


Little Known Facts About Alfalfa, Don Ball Feb 2000

Little Known Facts About Alfalfa, Don Ball

Kentucky Alfalfa and Stored Forage Conference

During the previous nineteen Kentucky Alfalfa Conferences, many topics pertaining to alfalfa have undoubtedly been addressed. In fact, some topics such as establishment techniques, varieties, and factors affecting yield are important enough that they have probably been discussed in one form or another during most of these conferences.

However, a twentieth-year state commodity conference is a milestone that deserves some special consideration, and which should justify inclusion of one or more unique topics on the program. This line of thinking led to idea that for this presentation it might be interesting to discuss some facts about alfalfa that are not …


Reducing Alfalfa Harvesting Losses, Michael Collins Feb 2000

Reducing Alfalfa Harvesting Losses, 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.


Opportunities For Alfalfa As A Grazing Crop In Kentucky, Ken Johnson Feb 2000

Opportunities For Alfalfa As A Grazing Crop In Kentucky, Ken Johnson

Kentucky Alfalfa and Stored Forage Conference

Why do we continue to hear people talk about Alfalfa as a grazing crop? In my opinion there are two words that come to mind when I think of grazing Alfalfa, quality and yield. Alfalfa is without a doubt the highest quality forage we can graze. Alfalfa is also one of the highest yielding forages we can graze and maybe the highest yielding widely known and widely grown forage available to Kentucky farmers.

An Alfalfa Disease Calendar, Paul Vincelli Feb 2000

An Alfalfa Disease Calendar, Paul Vincelli

Kentucky Alfalfa and Stored Forage Conference

The following calendar provides producers and agricultural professionals with insights that may improve alfalfa production in several ways. First, knowing when to expect certain diseases improves one's ability to diagnose disease problems, which is a fundamental foundation for disease management. The many UK Extension Service publications on alfalfa as well as publications like the Alfalfa Analyst and the Compendium of Alfalfa Diseases, all are useful for diagnosis, but none provides a precise calendar of when to expect activity of alfalfa diseases in Kentucky. An alfalfa disease calendar can also provide occasional insights into timely management practices. For example, being …


Fertilizing Alfalfa For Profit, Monroe Rasnake, Steven G. Isaacs Feb 2000

Fertilizing Alfalfa For Profit, Monroe Rasnake, Steven G. Isaacs

Kentucky Alfalfa and Stored Forage Conference

Alfalfa has the potential for producing high yields of high quality forage with good management. A key component of good management is supplying plant nutrients in adequate quantities and proper balance. In Kentucky, this requires fertilizing soils with agricultural limestone, commercial fertilizers and/or animal manures. Good soil fertility is necessary for alfalfa stand establishment, high yields and long stand life.
