Age Determination Of Recent Cave Deposits Using Excess 210Pb - A New Technique, M. Baskaran, Thomas M. Iliffe
Age Determination Of Recent Cave Deposits Using Excess 210Pb - A New Technique, M. Baskaran, Thomas M. Iliffe
Environmental Science and Geology Faculty Research Publications
Cave deposits have been widely used as proxy recorders in deciphering palaeoclimate during the last glacial/interglacial maxima (∼ 120 ka) [Harmon et al., 1975; Atkinson et al., 1978; Goede and Harmon, 1983; Ayliffe and Veeh, 1989]. Palaeoclimatic studies of cave deposits for the past 1–1000 yr time scale require a precise dating technique, that until now has been lacking. Due to the multiple sources of carbon in speleothems, 14C dates obtained for recently deposited calcite are highly variable and thus, 14C dating techniques are not suitable to obtain speleothem ages for the past 1–1000 years.

Producing And Marketing Kentucky Hay - A Challenge, Ed Logsdon
Kentucky Alfalfa and Stored Forage Conference
Many of you probably are aware that Kentucky's commodity organizations are working with UK, the Agriculture Department and Farm Bureau in developing a plan to improve farm income in the state. This is a very ambitious project involving more than 40 farm organizations, including the Kentucky Forage and Grassland Council. This group has set a lofty goal of attempting to raise gross farm sales in the state from its current $3 billion level to around $5 billion by the turn of the century.
Alfalfa For Hay And Grazing In Tennessee, Joe Burns
Alfalfa For Hay And Grazing In Tennessee, Joe Burns
Kentucky Alfalfa and Stored Forage Conference
Alfalfa has truly had its "ups and downs" in terms of acreage in Tennessee for the last 30 years. Just as the effect of a good fertilizer-lime-soil testing program was increasing the alfalfa acreage, the alfalfa weevil appears and begins to destroy the crop. With the aid of the insecticide heptachlor sprayed on the fertilizer, farmers continued to fertilize the alfalfa and kill the weevil at the same time.

Grazing Alfalfa — National Perspective, Warren C. Thompson
Kentucky Alfalfa and Stored Forage Conference
The production of alfalfa specifically for grazing is a fairly new practice. But now, farmers all around the USA are beginning to look toward alfalfa for a long living legume to increase yield, quality, and reliability all during the growing and grazing seasons. They also are looking for ways to reduce the cost of harvest, equipment, and storage costs, as well as weather-related harvest losses, and in time, reduced fertilizer costs.

Kentucky Alfalfa and Stored Forage Conference
Alfalfa has been grown in Kentucky for many years, but in the last decade, its acreage has increased dramatically- from 208,000 in 1978 to 350,000 in 1981 (Ky. Agri. Statistics Service). Alfalfa is generally thought of as a hay crop but the practice of grazing alfalfa has received considerable attention recently. Much of this interest was generated by "Graze-More-Beef" demonstrations which have been conducted in the state. Demonstrations in which alfalfa was grazed averaged 791 pounds per acre during 1986-1988. Alfalfa's ability to withstand dry weather and its excellent nutritional qualities make it an attractive grazing alternative to fescue - …
Do's And Don'ts Of Alfalfa Grazing, Ken Johnson
Do's And Don'ts Of Alfalfa Grazing, Ken Johnson
Kentucky Alfalfa and Stored Forage Conference
I usually start grazing in April when alfalfa is about 10 inches tall. I like to start with enough cattle to graze a paddock clean in two to five days, then move to another paddock, returning to re-graze in about 35 days. I usually need at least eight paddocks in the system. You must rotate cattle on Alfalfa for the stand to persist. It will take seven or eight head of 500 pound calves per acre to keep up with alfalfa growth in the spring. Part of the calves will need to be removed in June and maybe some more …

Grazing Alfalfa — County Perspective, Steve Osborne
Kentucky Alfalfa and Stored Forage Conference
Often the difference between successful farming operations and others is the ability of the producers to manage the available resources to their advantage. The rolling topography and plentiful supply of livestock water in Monroe County is well suited to forage production. The purpose of this program is to introduce new forage species, improve forage production, and increase producer profits.

Grazing Alfalfa — An Overview, Garry D. Lacefield, W. Roy Burris
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is the most important forage legume grown in the United States. Grown over a wide range of soil and climatic conditions it has the highest yield potential and feeding value of all perennial forage legumes. This versatile crop can be used for hay, pasture, silage, green-chop, pellets, cubes and soil improvement. Because of its many merits, especially yield, quality and versatility, it can be used successfully in many animal feeding programs.
Grazing alfalfa has not been practiced to any great extent in the U.S., but has been done extensively in other countries. Research and producer experience has shown excellent …

Quality From The Seed To The Sale To The Animal, Jimmy C. Henning, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
Forages in Kentucky have been valued at over $700 million annually. This figure combines receipts from cash hay sales to indirect value from the portion of beef, dairy, sheep, and horse receipts that are attributable to pasture and stored forages. However, the key to the maintaining and even increasing the value of forages to Kentucky lies in Quality: A) Quality of seed B) Quality as it relates to sales, and C) Quality as it relates to the animal.
New Developments In Hay Harvesting, Michael Collins
New Developments In Hay Harvesting, Michael Collins
Kentucky Alfalfa and Stored Forage Conference
Hay and pasture crops are critical to Kentucky Agriculture and to that of the entire temperate region of the US. The sale of cattle, calves and dairy products provide 29% of Kentucky's farm income compared with 23% for tobacco. Beef cowcalf enterprises comprise the majority of cattle numbers in the state, however, dairy production is also significant. A substantial horse industry also exists in Kentucky which is an excellent market for high quality alfalfa hay. At present a substantial amount of alfalfa for feeding horses in the state is imported.
My Observations And Experiences With Alfalfa, Larry Jeffries
My Observations And Experiences With Alfalfa, Larry Jeffries
Kentucky Alfalfa and Stored Forage Conference
I was raised on a small dairy farm in Henry County, Kentucky. I'm the oldest of six children and wanted to leave the farm as soon as possible. Upon graduation from Transylvania College in 1956, I was quickly drafted into the U.S. Army. I was sent to El Paso, Texas, for training and remained in the southwest for 11 (eleven) years.
In 1958 I married Carolyn Billman. We have 4 (four) children: Rae Lynne, Janet, Keith, and Joy.
Upon returning home to Henry County to farm and teach school in 1967, I found a catastrophe had happened to the alfalfa …

An Alfalfa Management Program For Optimum Yields And Quality, Bill Griffith
Kentucky Alfalfa and Stored Forage Conference
Alfalfa popularity is not surprising because it has the highest yield potential and the highest feeding value of all perennial hay crops. While the protein value of alfalfa is of major importance, its energy content is also high and should not be discounted. High yields of alfalfa harvested at the proper stage of maturity compare favorably with corn silage in production of energy.
Alfalfa Production And Trends In Kentucky, David D. Williamson
Alfalfa Production And Trends In Kentucky, David D. Williamson
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is often referred to as the "Queen of U.S. Forage Production". Looking at all hay production alfalfa should be called "The King". In 1991, 83.8 million tons were harvested in the United States -- 55 percent of all the hay harvested in the United States. This total does not include the many tons harvested as green chop, which is an especially common practice among dairy farmers. But, why shouldn't alfalfa be popular? This deep rooted leguminous plant is generally the forage leader in yield, protein, and TDN.

The Origin And Evolution Of The Southern Snake Range Decollement, East Central Nevada, Allen J. Mcgrew
The Origin And Evolution Of The Southern Snake Range Decollement, East Central Nevada, Allen J. Mcgrew
Geology Faculty Publications
Regional and local stratigraphic, metamorphic, and structural constraints permit reconstruction of the southern Snake Range extensional deformational system in east central Nevada. The dominant structure of the range, the southern Snake Range décollement (SSRD), operated during Oligocene and Miocene extensional deformation to exhume a footwall of multiply deformed metasedimentary and plutonic rocks. Intrusion of three plutons (∼160 Ma, 79.1 ± 0.5 Ma, and 36 ± 1 Ma, respectively) and development of two cleavages preceded the onset of extensional deformation. Plastic deformation of lower plate metasedimentary rocks accompanied the early phases of regional extension and produced bedding-parallel grain shape foliations and …

Soil Testing: Field, Sample And Laboratory Variability, Lloyd W. Murdock, Dan Kirkland, Phil Gillespie, Tim Gray
Soil Science News and Views
Soil testing has advanced as a science and has become a tool widely used in making fertilizer recommendations. One of the basic components for ensuring reliability of recommendations is calibration of soil test results to determine the proper match of fertilizer recommendations with the soil test level for each nutrient and crop. Generally, calibration has been accomplished on small plot areas and is quite accurate. Even though there is nutrient variability within small areas, the potential for variability is much greater on a field basis. An important factor in making reliable fertilizer recommendations is the assumption that the soil sample …

Broiler Litter For Topdressing Tall Fescue, Monroe Rasnake, David Watson
Soil Science News and Views
A test was started in Princeton in 1991 to observe the response of tall fescue to applications of nitrogen fertilizer and broiler litter. Five treatments were used: two and four tons of litter per acre, 100 lbs nitrogen (half in May and half in July), 100 lbs nitrogen plus soil test recommended rates of phosphate and potash (only 55 lbs of Phosphate applied in 1991) and a check which had no nutrients applied. The treatments began in May 1991 on an established stand of tall fescue on a fragipan soil at the U.K. Research and Education Center in Princeton.

Improving Sustainable Production From Water Repellent Sands, Paul Blackwell
Improving Sustainable Production From Water Repellent Sands, Paul Blackwell
Journal of the Department of Agriculture, Western Australia, Series 4
The agricultural management of water repellent ( non-wetting) sands is difficult, and production from them is mostly low. However, there are ways to make them more productive.
Furrow sowing and the incorporation of dispersive clay are two likely methods to make these soils easier to manage, more productive and more profitable than they are now.
This article discusses several aspects of our research on water repellent sands. In addition, some of the costs and benefits of alternative management strategies are outlined.
Establishment Of Lupin Seedlings, Miles Dracup
Establishment Of Lupin Seedlings, Miles Dracup
Journal of the Department of Agriculture, Western Australia, Series 4
Good seedbed conditions lead to high and rapid seedling emergence and vigorous seedlings best equipped to avoid disease, weed competition and sand-blasting. Good establishment is needed for a high yielding crop.
In Western Australia, seedbed moisture and temperature are most likely to limit successful emergence of lupins, especially with the trend toward early sowing.
Research by the Department of Agriculture is helping to define seedbed temperature and moisture requirements for successful lupin establishment that will help future research for improving seedbed conditions.

Journal of the Department of Agriculture, Western Australia, Series 4
A new rotary blade soil sampler has taken the hard work out of collecting soil samples from Western Australia's hard-setting soils to test for soil phosphorus levels .
Conceived and developed by Department of Agriculture technical officer Mike Baker, it should enable soil testing to be more widely adopted. Fortunately, the soil calibration tests that were developed using pogo samples can also be used for the new sampler.

Controlling Wind Erosion In Field Pea Stubbles, Jeff Russell
Controlling Wind Erosion In Field Pea Stubbles, Jeff Russell
Journal of the Department of Agriculture, Western Australia, Series 4
The area sown to field peas in Western Australia's eastern wheatbelt has increased from 4000 ha in 1985 to about 35, 000 ha in 1992.
While field peas can be grown on soil types not suited to lupins, their stubble is highly fragile and prone to wind erosion, even at low grazing pressure. This is one reason why some farmers are hesitant to grow field peas.
Haroest losses of field peas can also be high; levels of JOO to 200 kg/ha of seed on the ground are not uncommon. For this reason farmers believe the stubbles should be grazed.
