Irrigated Field Crop Acres In Kentucky, Lloyd W. Murdock
Irrigated Field Crop Acres In Kentucky, Lloyd W. Murdock
Soil Science News and Views
Irrigation in Kentucky has always been limited. This is due to a limited water supply in many parts of Kentucky and the high amount of rainfall in the state which reduces the chances for a consistent profitable response to field crops.
Coal Resources Of The Lower Elkhorn Coal Bed In Eastern Kentucky, Ernest E. Thacker, Gerald A. Weisenfluh, William M. Andrews Jr., John K. Hiett
Coal Resources Of The Lower Elkhorn Coal Bed In Eastern Kentucky, Ernest E. Thacker, Gerald A. Weisenfluh, William M. Andrews Jr., John K. Hiett
Map and Chart--KGS
This chart is one of a series that shows the regional characteristics of the Lower Elkhorn coal. The maps were prepared as part of the U.S. Geological Survey's Natural Coal Assessment Program, which compiles regional maps and databases that provide a comprehensive assessment of the most important coal beds in the nation. The Lower Elkhorn coal is one of the leading producers in the state of Kentucky and has, in some areas, a reputation as an excellent metallurgical-grade coal. It is known locally as the Pond Creek, Imboden, Path Fork, Blue Gem, Straight Creek, Bruin or Vires coal bed. This …
Effects Of Longwall Mining On Hydrology, Leslie County, Kentucky Part 2: During-Mining Conditions, Shelley Minns Hutcheson, James A. Kipp, James S. Dinger, Lyle V.A. Sendlein, Daniel I. Carey, Gregory L. Secrist
Effects Of Longwall Mining On Hydrology, Leslie County, Kentucky Part 2: During-Mining Conditions, Shelley Minns Hutcheson, James A. Kipp, James S. Dinger, Lyle V.A. Sendlein, Daniel I. Carey, Gregory L. Secrist
Report of Investigations--KGS
The effects of longwall coal mining on hydrology in the Eastern Kentucky Coal Field are being investigated. The study area is in the Edd Fork watershed in southern Leslie County, over Shamrock Coal Company's Beech Fork Mine. Longwall panels approximately 700 ft wide are separated by three-entry gateways that are approximately 200 ft wide. The mine is operated in the Fire Clay (Hazard No. 4) coal; overburden thickness ranges from 300 to 800 ft. Mining began in panel 1 in September 1991 and concluded with panel 8 in September 1994. Long-term monitoring consisting of a network of piezometers and time-domain …

The Effect Of Turfgrass Maintenance On Surface-Water Quality In A Suburban Watershed, Inner Blue Grass, Kentucky, R. Michael Williams, James S. Dinger, Andrew J. Powell, Dwayne R. Edwards
The Effect Of Turfgrass Maintenance On Surface-Water Quality In A Suburban Watershed, Inner Blue Grass, Kentucky, R. Michael Williams, James S. Dinger, Andrew J. Powell, Dwayne R. Edwards
Report of Investigations--KGS
Nutrients and pesticides applied during routine maintenance or establishment of turfgrass could result in nonpoint-source pollution. Nutrient and pesticide concentrations in water exiting a turfgrass management area in the Sinking Creek watershed, a suburban watershed in the Inner Blue Grass Region of central Kentucky, were monitored. This watershed was selected because it contains multiple land uses: agricultural, residential, and recreational (golf course).
A survey was conducted to determine the extent to which lawn-care products are used in the residential sector of the watershed. For the golf-course portion, the golf-course superintendent recorded chemical application daily.
Runoff from the golf course was …

Generalized Geologic Bedrock Conditions As Related To Solid-Waste Landfills In Kentucky, Martin C. Noger
Map and Chart--KGS
This map is not intended to be used for selecting individual landfill sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions throughout the state that affect the selection of solid-waste disposal sites.

Quality Characteristics Of The Springfield Coal In Western Kentucky, Cortland F. Eble
Map and Chart--KGS
Thickness and quality data from the Kentucky Coal Resources Information System (KCRIS) for the Springfield coal bed are summarized in this chart. Parameter averages and range of values are presented in the two tables, and average values are displayed graphically by county.
Geologic Map Of Kentucky, Garland R. Dever Jr., M. C. Noger
Geologic Map Of Kentucky, Garland R. Dever Jr., M. C. Noger
Map and Chart--KGS
This map shows the geologic age of rocks and sediments at the surface in Kentucky. Sedimentary rocks, deposited from about 465 to 290 million years ago during the Ordovician, Silurian, Devonian, Mississippian, and Pennsylvanian Periods, crop out across the state. The rocks mainly consist of shale, limestone, sandstone, and siltstone. As shown in the cross sections, these surface rocks are underlain by older unexposed rocks of Precambrian, Cambrian, and Ordovician age.
Small bodies of igneous rocks were intruded into the state's bedrock about 270 million years ago during the Permian Period. They crop out in Elliott County of northeastern Kentucky, …
