Forage Testing & Marketing Program, Allen Johnson
Kentucky Alfalfa and Stored Forage Conference
Two thousand and three marks the 141th year for the Kentucky Department of Agriculture for testing forages. We continue to strive to offer a quality service to producers at the very least cost possible. After all these years we continue to charge only $10.00 per lot or cutting and have expanded our services to try to meet the needs of our forage and livestock producers. In January 2002, we introduced the testing of haylages and have expanded this to cover most of the haylage crops harvested in Kentucky. In cooperation with The University of Kentucky Extension Service, the department …
Producing Quality Alfalfa Hay, Jimmy C. Henning, Garry D. Lacefield
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.

Alfalfa And Mrls: What We Know After One Year Of Testing, Jimmy C. Henning, Wayne Long
Kentucky Alfalfa and Stored Forage Conference
The onset of mare reproductive loss syndrome in April 2001 in Kentucky lead to much speculation about its cause. Some of these initial 'suspects' included the ergot alkaloids of tall fescue, potential cyanide content of white clover, wide Calcium/Potassium ratios in pasture, fungal mycotoxins and the presence of certain poisonous plants. Certain consultants also indicated that no one should purchase or feed any Kentucky hay in 2001. However, these statements were not based on any hard information, just one person's opinion. But great damage was done to the confidence in Kentucky grown hay.
Alfalfa, The Queen Of Forage Crops — Reflections After Sixty Years Experience With The Crop, Warren C. Thompson
Alfalfa, The Queen Of Forage Crops — Reflections After Sixty Years Experience With The Crop, Warren C. Thompson
Kentucky Alfalfa and Stored Forage Conference
Yes, it is true I have been involved with alfalfa for 60 years and then some. Fact is I was fortunate enough to pick the World's best forage on which to base much of my career about the same time I fell in love with and married the best lady I ever knew. Betty has stuck with me through these crazy wonderful years. She was largely responsible for matters at home and raising the family. She managed our family and home while I was on the move trying to encourage maybe even coerce farmers in Kentucky and then over the …

Alfalfa For Summer Grazing, Jason Sandefur
Kentucky Alfalfa and Stored Forage Conference
Jason manages the Berle Clay Farm in Paris, Kentucky. The farm has been in the Clay family since the 1770's. The Homestead was built in 1778.
The farming operation consist of approximately 680 acres of orchardgrass-clover, 300 acres of orchardgrass-alfalfa, 210 acres of tall fescue-clover, 100 acres of crops, 13 acres of tobacco and 70 acres in roads, buildings, etc.
Advances In Developing Better Alfalfa Varieties, Jim Moutray
Advances In Developing Better Alfalfa Varieties, Jim Moutray
Kentucky Alfalfa and Stored Forage Conference
Alfalfa breeders continue to actively pursue the development of varieties that will bring more benefits to farmers. Yield and better persistence are our highest priorities. Other traits under selection can make alfalfa easier and cheaper to grow, better and safer for livestock and more attractive to livestock.
The goal of this paper is to update you on the types of alfalfa research going on in the U.S., time tables on when you may expect to see these new developments and how they may help you in your operation.
Alfalfa Hay Quality: Terms And Definitions, Garry D. Lacefield
Alfalfa Hay Quality: Terms And Definitions, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
At the 22nd Kentucky Alfalfa Conference we discussed the relationship among Alfalfa - Yield-Quality-Persistence. In our presentation, we indicated that all three components must be considered for best management of alfalfa stands. Over the past week, I have looked through the past twenty-two years of Alfalfa Conference Proceedings. It's interesting, but not surprising that we have focused far more attention on yield than on quality and/or persistence.
Alfalfa yield (quantity) and quality are both important; however, it is easier for producers to recognize problems associated with quantity than quality because quantity can be easily assessed visually. Thus, forage quantity …

Physics and Astronomy Faculty Publications
The intensity of the strong N V λ1240 line relative to C IV λ1549 or to He II λ1640 has been proposed as an indicator of the metallicity of quasi-stellar object (QSO) broad emission line regions, allowing abundance measurements in a large number of QSOs out to the highest redshifts. Previously, it had been shown that the (normally) much weaker lines N III] λ1750 and N IV] λ1486 could be used in the same way. The redshift 1.96 QSO 0353-383 has long been known to have N III] and N IV] lines that are far stronger relative to Lyα or …

We show that the mass of ionized gas in the broad-line regions (BLRs) of luminous quasars is at least several hundred M☉, and probably of the order of 103-104 Msolar. BLR mass estimates in several existing textbooks suggest lower values but pertain to much less luminous Seyfert galaxies or include only a small fraction of the ionized/emitting volume of the BLR. The previous estimates also fail to include the large amounts of BLR gas that emit at low efficiency (in a given line) but that must be present based on reverberation and other …

Physics and Astronomy Faculty Publications
We present Hubble Space Telescope (HST)/STIS long-slit spectroscopy of NGC 1976. Our goal is to measure the intrinsic line ratio [O III] 4364/5008 and thereby evaluate the electron temperature (Te) and the fractional mean-square Te variation (t2A)across the nebula. We also measure the intrinsic line ratio [N II] 5756/6585 in order to estimate Te and t2A in the N+region. The interpretation of the [N II] data is not as clear cut as the [O III] data because of a higher sensitivity to knowledge …
Precision Farming In Central Kentucky: Evaluating Public And Private Sector Influence On The Adoption Decision, Rod Grusy
Soil Science News and Views
The Cooperative Extension Service is challenged to assess the needs of customers who are unable or unwilling to try new production techniques with the potential to increase profitability. Precision Farming (PF) is a production technique that has the goal of maximizing economic potential by using technology that recognizes variability within fields. Ample research from the last decade shows that precision technologies hold promise for enhanced agricultural profitability. A study conducted in three Central Kentucky counties in 2001 shows that farmers obtain information for decision-making related to PF technologies from their local fertilizer dealer and the Cooperative Extension Service but are …
Value Of Nutrients In Poultry Litter When Applied In The Fall, Monroe Rasnake, George Kelley
Value Of Nutrients In Poultry Litter When Applied In The Fall, Monroe Rasnake, George Kelley
Soil Science News and Views
The value of nutrients in poultry litter depends not only on how much nitrogen (N), phosphorus (P) and potassium (K) it contains, but also on how it is handled and applied. The following table compares the value of 19 poultry litter samples from Hopkins County analyzed for N, P & K and the litter then spread in the fall. The samples include pullet, breeder and broiler manures, with storage times up to one year. Nutrient values were based on a comparison with urea (46-0-0) at $199/ton, triple super phosphate (0-46-0) at $215/ton and muriate of potash (0-0-60) at $165/ton.
Controls On Middle To Late Ordovician Synorogenic Deposition In The Southeastern Corner Of Laurentia, German Bayona
Controls On Middle To Late Ordovician Synorogenic Deposition In The Southeastern Corner Of Laurentia, German Bayona
University of Kentucky Doctoral Dissertations
Middle and Upper Ordovician strata in the southernmost Appalachians document initial collision along the southeastern margin of Laurentia during the Blountian orogeny, an early phase of the Taconic orogeny. Coeval drowning and exposure of different parts of the former platform and variations in stratal architecture have been attributed to tectonic and depositional loading along the collisional margin. Stratigraphic correlations, using a bentonite-graptoliteconodont time framework, a palinspastic map, and a map of subsurface basement structures, suggest that basement-fault reactivation, flexural subsidence, and eustasy variously controlled uplift, subsidence, and deposition at different sites within the peripheral foreland basin. This dissertation documents how …
Fixed Points Of Holomorphic Mappings For Domains In Banach Spaces, Lawrence A. Harris
Fixed Points Of Holomorphic Mappings For Domains In Banach Spaces, Lawrence A. Harris
Mathematics Faculty Publications
We discuss the Earle-Hamilton fixed-point theorem and show how it can be applied when restrictions are known on the numerical range of a holomorphic function. In particular, we extend the Earle-Hamilton theorem to holomorphic functions with numerical range having real part strictly less than 1. We also extend the Lumer-Phillips theorem estimating resolvents to dissipative holomorphic functions.

Map and Chart--KGS
This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site to site basis. At any site, it is important to understand both the soils, and the underlying rock.

Total Thickness Of The Amburgy Coal In Eastern Kentucky, Michael G. Shultz, Jeffery A. Esterle, Ernest E. Thacker
Map and Chart--KGS
This map showing the regional characteristics of the Amburgy coal bed was prepared as part of the U.S. Geological Survey's National Coal Assessment program, which compiles regional maps and databases that provide a comprehensive assessment of the most important coal beds in the nation. The Amburgy coal zone is composed of a number of distinct coal beds that merge in some areas to form mineable coal bodies. For the purpose of this assessment, the zone has been divided into two beds; the Lower Amburgy (A) and Upper Ambury (B). The lower bed is of greatest economic significance and is the …

Mapped Karst Groundwater Basins In The Harrodsburg 30 X 60 Minute Quadrangle, James C. Currens, Randall L. Paylor, Joseph A. Ray
Map and Chart--KGS
This map shows karst groundwater basins in the Harrodsburg quadrangle, determined primarily by groundwater tracer studies. It can be used to quickly identify the groundwater basins and springs to which a site may drain. Major springs and the relative size of their basin or catchment areas can be evaluated for potential as water supplies. The map also serves as a geographic index to literature on karst groundwater in the area.

Mining Geology Of The Fire Clay Coal, Stephen F. Greb
Mining Geology Of The Fire Clay Coal, Stephen F. Greb
Map and Chart--KGS
The Fire Clay (Hazard No. 4) coal is one of the leading producers in the Eastern Kentucky Coal Field, with more than 20 million short tons of annual production and 230 million short tons mined between 1976 and 1992, according to Kentucky Department of Mines and Minerals data. Regional thickness and resources of the coal are calculated in Greb and others (1999c) and Thacker and others (2000a, b).
Stratigraphically, the coal occurs in the middle part of the Hyden Formation of the Breathitt Group (Fig. 1), which was previously part of the Breathitt Formation (Chesnut, 1992). The coal occurs between …
