Subsoiling Of No-Tilled Corn, Lloyd W. Murdock
Subsoiling Of No-Tilled Corn, Lloyd W. Murdock
Soil Science News and Views
No-tillage corn production has become very popular in Kentucky because of the advantages it offers producers. Currently, over half of the corn in Kentucky is planted by this method and even a higher percentage is no-till planted on erodible lands. Because of this, many fields have received little tillage in the last 10 to 20 years. Many producers wonder if soil compaction increases with time on these long-term no-tilled fields due to annual trafficking by heavy equipment. Subsoiling implements have become available that allow subsurface tillage while preserving the surface mulch layer. This practice allows for continued no-till planting while …

Tectonic Implications Of Erosional And Depositional Features In Upper Meramecian And Lower Chesterian (Mississippian) Rocks Of South-Central And East-Central Kentucky, Garland R. Dever Jr.
Tectonic Implications Of Erosional And Depositional Features In Upper Meramecian And Lower Chesterian (Mississippian) Rocks Of South-Central And East-Central Kentucky, Garland R. Dever Jr.
Bulletin--KGS
Erosional and depositional features in upper Meramecian and lower Chesterian (Mississippian) carbonate rocks of south-central and east-central Kentucky suggest the influence of coeval structural activity. The study area, which extends from Pulaski County northeastward into Powell County, is underlain by (1) the Greenwood Anomaly, a large north-trending gravity anomaly, which probably represents part of a Precambrian rift system, and (2) the western part of the Rome Trough, an east-trending graben-like structure, which represents a Late Precambrian to Cambrian continental rift zone. The study focused on the St. Louis Limestone and lower Monteagle Limestone of south-central Kentucky and correlative carbonate rocks …

Information Circular--KGS
Fluoride (F-) is an ion of the element fluorine, and is a natural component in most water resources. According to Hem (1989), fluoride concentrations in fresh water are generally less than 1 mg/L (milligrams per liter), and the concentration of fluoride in the world's oceans is about 1.3 mg/L. The source of most fluoride in natural fresh-water resources is various rocks and minerals in bedrock and sediments.
Mass Flux Of Agricultural Nonpoint-Source Pollutants In A Conduit-Flow-Dominated Karst Aquifer, Logan County, Kentucky, James C. Currens
Mass Flux Of Agricultural Nonpoint-Source Pollutants In A Conduit-Flow-Dominated Karst Aquifer, Logan County, Kentucky, James C. Currens
Report of Investigations--KGS
Changes in water quality in a karst ground-water basin used intensively for agriculture are being measured before, during, and after the implementation of best management practices (BMP’s) and other management practices, to determine the success of such programs in protecting ground water. The study was divided into three phases. The results of the first two phases are included in this report and cover research conducted between August 1990 and October 1994. During phase I of the study the overall ground-water quality of the basin and its hydrogeology were investigated. Phase II began monitoring the water quality at Pleasant Grove Spring …
