The Corn Belt Multi-State Corn Nitrogen Rate Calculator: Not Reliable For Kentucky Corn Producers, John H. Grove, Gregory J. Schwab
Soil Science News and Views
Because of the rising price of nitrogen (N) fertilizer, university personnel across the country are in the process of fine tuning N recommendations for com. Historically, each state has had different N recommendations based on research results obtained in different production systems and growing environments across each state. Some states in the Com Belt have used a yield potential (yield goal) approach to N recommendations. The expected yield is multiplied by a factor (usually 1.2) and then N credits for previous crop, manure, etc. are subtracted. One problem with this method is that as com yields increase N recommendations also …

Generalized Geologic Map For Land-Use Planning: Nelson County, Kentucky, Stephen F. Greb, Bart Davidson, Daniel I. Carey
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 the characteristics of both the soils and the underlying rock.

Stratigraphic Column Of The Kope And Fairview Formations, Kentucky 445, Brent, Kentucky, Steven M. Holland, Arnold I. Miller, David L. Meyer, Benjamin F. Dattilo, Sharon C. St. Louis Diekmeyer
Map and Chart--KGS
The Upper Ordovician Kope Formation is exposed over a broad area of southwestern Ohio, southeastern Indiana, and northern Kentucky (Weir and others, 1984). Roadcuts along Ky. 445 near Brent (Figs. 2-3) and adjacent roadcuts along Interstate 275 expose a nearly complete section of the Kope Formation as well as the overlying Fairview Formation.

Groundwater Quality In Kentucky: Barium, Bart Davidson, R. Stephen Fisher
Information Circular--KGS
Barium is a silver-white alkaline earth metal that is not found free in nature because it is highly reactive with sulfate and carbonate. Barium compounds can be naturally occurring or man-made. The most common natural occurrence of barium is in the mineral barite (barium sulfate), which has many uses in industry, such as a filler in the making of rubber, plastic and resin, white pigment, drilling lubricants used in the oil and gas industry, paint, bricks and glass (Agency for Toxic Substances and Disease Registry, 2004). Barium sulfate is very slightly soluble in water and absorbs X-rays, making it an …

Chemical Analysis Of Fish Tissue: Kentucky Army National Guard Wendell H. Ford Western Kentucky Training Site, Muhlenberg County, Kentucky, Steven E. Webb, James S. Dinger, Dennis H. Cumbie
Information Circular--KGS
Thirty-one analytes were measured in fish tissue taken from largemouth bass, catfish, and bluegill harvested from lakes and ponds in reclaimed and unreclaimed coal-mine spoil of Pennsylvanian age. The spoil area is approximately 7,756 acres created primarily from surface mining, and has been used in increasing intensity since 1969 as a training site by the Kentucky Army National Guard. Four fish were harvested for analysis from the area of unreclaimed spoil that resulted from mining prior to 1977, and 15 fish were harvested for analysis from the part of the training facility that was reclaimed by 1985. Twenty-six analytes had …
