Advances In Alfalfa Seed Coating, Bill Talley

Kentucky Alfalfa and Stored Forage Conference

Seed coating for alfalfa has been available since the mid to late 70’s. Over the last 30 years, advances in the industry have made it the choice of many producers. The purpose of the coatings at that time was mainly to add weight to increase the ballistic properties and to be a carrier for the rhizobia. Through research and new technology, coatings have evolved and shown great agronomic benefits. Seed coating can provide an opportunity to supply effective quantities of needed materials to each seed, which can influence both the physical property, and the microenvironment of the seed. Coatings can …

Impact Of Alfalfa In Lincoln County, Dan Grigson

Kentucky Alfalfa and Stored Forage Conference

Lincoln County is located 45 miles south of Lexington, Kentucky. It is part of 3 geographical regions of the state-the outer Bluegrass, the Knobs, and the Eastern Pennyroyal area. Thus the land ranges from moderate sloping fields that can be row cropped to fields that are nearly too steep to mow. The majority of the land is best suited for hay and pasture production. The soil fertility is moderately high with limestone, sandstone, shale and siltstone parent material. The land is very well suited to growing very productive forage crops.

Teaching Stand Management Using Virtual Alfalfa Plants, S. Ray Smith, Lars Muendermann, Av Singh

Kentucky Alfalfa and Stored Forage Conference

A ‘virtual’ alfalfa plant model was developed at the University of Manitoba in Canada as part of a comprehensive grazing research project. This model shows an alfalfa plant ‘growing’ on a computer screen and the plant’s response to grazing (similar to time-lapse photography). The original model was designed and constructed by Av Singh to show the research potential of visually modeling alfalfa plant growth. The ability to visually ‘grow’ a plant on a computer screen also provides an excellent teaching and extension tool.

Generalized Geologic Map For Land-Use Planning: Logan County, Kentucky, E. Glynn Beck, David A. Williams, Daniel I. Carey

Map and Chart--KGS

This map is not intended to be used for selecting individual sites. Its purpose if 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 the characteristics of both the soils and the underlying rock.

Structure And Isopach Maps Of The Mississippian "Big Lime" (Newman Limestone/Slade Formation), Eastern Kentucky, David C. Harris, Thomas N. Sparks

Map and Chart--KGS

The maps included in this publication were made using stratigraphic data collected by us from almost 8,000 wells as part of a regional stratigraphic study of the Mississippian Slade Formation in eastern Kentucky. The data extend from the Mississippian outcrop belt along the northwestern edge of the map area to the state borders on the northeast. The southeastern border of the map area is marked by the Pine Mountain Fault.

Formation tops data for these wells were collected from geophysical (electric) logs and drillers' logs, and are available in electronic format from the Kentucky Geological Survey (Harris and Sparks, 1997). …

Cross Section Of The Upper Elkhorn Coal Zone Between The Evarts And Benham Quadrangles, Bradford L. Luckett

Map and Chart--KGS

This cross section shows lithic variation and coal-bed correlations for the interval between the Upper Elkhorn No. 1 (Harlan) and the Upper Elkhorn No. 3 ½ coals in Harlan County, Ky. It is one of a series being made to document the characteristics of the Upper Elkhorn coal zone in eastern Kentucky. The data are derived from the KGS coal borehole database, which contains records of exploration core holes supplied by coal companies. Lines on the diagram show general bed correlations and indicate places where mineable coal beds split into two or more thinner benches. The vertical alignment of logs …

Evaluation Of A Mechanical System For Reconstructing Soil On Surface Mined Land, John P. Fulton, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

The existence of excessive soil compaction has hindered the surface mining industry from returning land to pre−mining productivity after reclamation, especially on prime farmland soils. Heavy earthmoving equipment used during reclamation tends to generate root−limiting bulk densities that adversely affect plant growth thereby decreasing yields. Therefore, the purpose of this study was to evaluate a mechanism, called the ‘Soil Regenerator,’ which reconstructs soil media at minimum bulk density during surface mine reclamation. The prototype soil forming mechanism was mounted on the front of a conventional bulldozer. Soil was placed in long narrow windrows by a scraper or bulldozer. As the …

Groundwater Quality In Kentucky: Mercury, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Mercury is a naturally occurring metal that occurs in trace amounts in water, soils, and rocks. Elemental mercury is a liquid that occurs in some ore deposits; it may also be concentrated around hot springs. Currently, about 50 percent of mercury use is for electrical products such as dry-cell batteries, fluorescent lights, switches, and other control equipment. Mercury is also used in the electrolytic preparation of chlorine gas and caustic soda, and in paint manufacture and pesticide production (U.S. Environmental Protection Agency, 2002). In the past, significant amounts of mercury were used in thermometers and pressure gauges.

Groundwater Quality In Kentucky: Selenium, Bart Davidson, R. Stephen Fisher

Information Circular--KGS

Selenium is a naturally occurring element found in most rocks and soils (Agency for Toxic Substances and Disease Registry, 2003). In its solid form, selenium is black, gray, or red and is odorless (New Jersey Department of Health and Senior Services, 2002). Most selenium is obtained from byproducts of the copper refining industry. Selenium compounds are often used in electronic components, photocopiers, metal alloys, rubber, paint pigments, glass-making (ruby red glass), and photographic emulsions (U.S. Environmental Protection Agency, 2003). Selenium exhibits both photovoltaic and photoconductive properties. As more light shines on selenium, its electrical conductivity increases, making it extremely useful …

Lithostratigraphy Of Precambrian And Paleozoic Rocks Along Structural Cross Section Ky-1, Crittenden County To Lincoln County, Kentucky, Martin C. Noger, James A. Drahovzal

Report of Investigations--KGS

This east–west cross section across western Kentucky is one of a network of regional cross sections prepared by the Illinois Basin Consortium that illustrate the structural and stratigraphic framework of the Illinois Basin. The structural cross section uses wireline logs of deep tests, as well as proprietary reflection seismic data, to show the relationship of Paleozoic rocks to each other from the surface to the top of the Precambrian unconformity.

The line of the cross section extends east from the complexly faulted Western Kentucky Fluorspar District across the Moorman Syncline and the underlying Rough Creek Graben to the Cincinnati Arch …
