Compact – A Reclamation Soil Compaction Model Part Ii. Sensitivity Analysis And Applications, Ronald L. Bingner, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

COMPACT, a physically based, event-oriented compaction model, was developed as a management or research tool to evaluate the influence of a surface mining system on compaction of soil material during reclamation. Two systems of area mining reclamation operations were simulated by COMPACT. The first system involved scrapers and bulldozers and the second also included trucks. Scrapers or trucks were used to pick up and deposit the soil material. Bulldozers were then used to shape the site for reclamation. The simulated results were compared with measured results and show how equipment patterns and soil parameters can affect overall soil compaction. This …

Dollars And Sense Of Alfalfa: Marketing Your High Yield, High Quality Alfalfa At High Prices, David C. Petritz

Kentucky Alfalfa and Stored Forage Conference

It seems every farmer wants to be in the commercial hay business--growing hay for the cash market. Have you ever stopped to think about the amount of hay that would be produced if everyone who talked about producing hay actually produced hay?

Chemical, Biological And Machinery Aids For Quality Haymaking, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

Hay and pasture crops are critical to Kentucky Agriculture and to that of the entire temperate region of the US. The sale of cattle, calves and dairy products provide 29% of Kentucky's farm income compared with 23% for tobacco. Beef cow-calf enterprises comprise the majority of cattle numbers in the state, however, dairy production is also significant. A substantial horse industry exists in Kentucky which is an excellent market for high quality alfalfa hay. At present a substantial amount of alfalfa for horse feeding in the state is imported.

Alfalfa In My Cash Hay Operation, Nicky Baker

Kentucky Alfalfa and Stored Forage Conference

I'm Nicky Baker, a fifth generation farmer from the Fredonia Valley's area in Western Kentucky. My current farming operation consists of 65 acres alfalfa, 100 · acres of row crops, (basically a corn, wheat, soybean double-crop rotation) and 2.5 acres of burley tobacco. I also have a 50 cow beef herd.

I remember having alfalfa on our farm before the weevil days of the '60's caused farmers to stop growing it. In those days, most of the farms had alfalfa and the majority of them had dairy cattle. The grain explosion of the '70's further curtailed alfalfa acreage, thereby providing …

Alfalfa In Our Horse Operation, Ben H. Crawford

Kentucky Alfalfa and Stored Forage Conference

"There's nothing better for the inside of man than the outside of a horse and there's nothing better for the inside of a horse than alfalfa hay".

Our operation consists of approximately 500 acres of rolling clay land. We lease an additional 100+ acres for alfalfa and other hay production. Our rotational program includes com, soybeans, wheat, oats followed by either red cloverorchardgrass or alfalfa-orchardgrass for hay and pasture.

Alfalfa In The Shirley Dairy Operation, Gary Tilghman, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Mr. Larry Thomas Shirley grew up on a small dairy farm in southern Barren County, Kentucky where they milked 25 cows by hand. In 1960 he graduated from Austin-Tracy High School and attended Western Kentucky University for 2 years. He has also taken several other hours of class time at night. In 1962, he married Martha Spillman and they have 3 children; Debra 26, John 14 and Ben 11.

Mr. Shirley's first job was as a computer operator for Malone & Hyde, a wholesale grocery company. He worked in this position from 1962-1968. In 1968 he worked for Glasgow Manufacturing …

Alfalfa In My Beef Operation, Jay Quisenberry

Kentucky Alfalfa and Stored Forage Conference

I have had two failures seeding alfalfa in the past few years. Once I seeded into land that had been in no-till com only one year. I found that fescue came back into that stand of alfalfa and took it in several years. Another time I seeded alfalfa into land that had been in com for a few years but had not been seeded down properly. I thought I could no-till alfalfa in that piece of ground and there would not be too much competition. But I was wrong again. I realize that both times I could have come back …

Alfalfa In Beef Backgrounding Programs, G. D. Cantrill

Kentucky Alfalfa and Stored Forage Conference

Alfalfa can be a very important part of most beef backgrounding operations. Today I want to look at two ideas about alfalfa.

First, why we should consider making alfalfa our most important crop on a farm that's backgrounding. Secondly, what are some of the ways to best utilize the alfalfa we do produce?

We can say a lot of positive things about why alfalfa can be important to a beef backgrounder. In preparing for this presentation, I talked with several producers about why they grow and feed alfalfa. Most often I came away with the thought: Alfalfa improves cash flow.

Advances In Grazing Alfalfa, Charles T. Dougherty

Kentucky Alfalfa and Stored Forage Conference

Many farmers are reluctant to develop a new enterprise based on the grazing of alfalfa if they have had no experience with grazing of this species. Their first negative reaction is usually based on their fear of legume bloat. Often their second reaction is that grazing will destroy the alfalfa stand in short order. Another response is that grazing is a wasteful and inefficient use of a valuable resource generating less income than conventional uses, such as hay and silage. Another reaction is based on the fear Alfalfa grazing, according to other sceptics, also requires lots of capital for fencing …

Is Ridomil Recommended When Seeding Alfalfa?, Paul C. Vincelli

Kentucky Alfalfa and Stored Forage Conference

Ridomil 2E® fungicide received a federal label in 1991 for control of seedling diseases of alfalfa caused by Pythium and Phytophthora fungi. Pythium fungi are widespread in Kentucky soils but can be controlled with Apron^® seed treatment. Phytophthora is less common in Kentucky soils. Where present, Phytophthora can usually be controlled with a combination of resistant varieties and Apron seed treatment. Occasionally, yield increases may be observed using Ridomil in fields highly infested with Phytophthora. However, broadcast applications of Ridomil at seeding are not recommended for most alfalfa fields in Kentucky.

Alfalfa Varieties, Jimmy C. Henning, Linda Brown, Garry D. Lacefield, Leonard M. Lauriault

Kentucky Alfalfa and Stored Forage Conference

Alfalfa (Medicago sativa) is the highest yielding, highest quality legume forage crop raised in Kentucky. This crop forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef and sheep diets. In 1990, 320,000 acres of alfalfa were produced in Kentucky, averaging 3.4 tons of dry matter yield per acre. At $75 per ton, the value of this alfalfa to Kentucky farmers would be $81.6 million.

This report will provide current yield data on alfalfa varieties currently in the Kentucky Alfalfa Variety Trials. Also, guidelines on selecting alfalfa varieties will be discussed.

Water Quality In The Kentucky River Basin, Daniel I. Carey

Information Circular--KGS

Data gathered up to 1990 suggest that water pollution problems existed throughout the Kentucky River Basin. Fecal coliform bacteria in streams was a widespread problem because of the inadequate treatment of municipal wastes, failing septic systems, and agricultural runoff. Iron, lead, manganese, mercury, and silver exceeded State standards and Federal guidelines for drinking water and aquatic life at most of the sample sites for a majority of samples. Aquatic life in many smaller streams in the Knobs region was reduced by chloride discharges from oil and gas operations, according to the Kentucky Division of Water. Organic enrichment and high nutrient …

Soil And Water Conservation Provisions Of The 1990 Food, Agriculture, Conservation And Trade Act, Monroe Rasnake, Bob Eddleman, Tommy Howard

Agriculture and Natural Resources Publications

Soil conservation is not new in Kentucky. Most farmers are aware of the need to protect soil and have used practices such as crop rotation, residue management, contour tillage, sod waterways, and no-till for many years. However, soil erosion is of neverending concern and still remains a problem in many areas.

Current Research On Soil Nitrate Testing For Corn In Kentucky, John H. Grove

Soil Science News and Views

Concern has been expressed that growers do not have the "slte-specific" information they need for more efficient nitrogen (N) fertilizer management on a field-by-field basis. Soil testing has routinely been used to guide recommendations for phosphorus, potassium, and lime additions to individual fields, but effective soil N test procedures have long eluded soil scientists working in warm, humid regions with substantial winter rainfall. Now, recent research suggests that a new soil test procedure has some potential to guide fertilizer N applications for corn. The purpose of this report is to define the concept of soil nitrate testing; to describe how …

Effects Of Tillage And Grass Filter Strips On Surface Runoff Of Water, Nitrate, Sediment, And Atrazine, C. E. Madison, Robert L. Blevins, Wilbur Frye

Soil Science News and Views

The contamination of streams and other natural bodies of water through agricultural runoff has become a very important environmental issue. Surface water runoff can contain heavy loads of sediment and/or agricultural chemicals, such as nitrogen and atrazine. Conservation tillage methods with vegetative filter strips downslope from cropped fields help· to combat this problem. Conservation tillage has proven effective in decreasing erosion by decreasing exposure of the soil surface to rainfall. Vegetative filter strips provide an area where sediment and agricultural chemicals from cropland can be deposited before the runoff reaches a body of water.

Poultry Litter As A Nitrogen Source For Corn, Monroe Rasnake, Larry Reber

Soil Science News and Views

Development of an intensive poultry production industry in western and south-central Kentucky will make poultry litter available to many farmers. It is estimated that 45, 000 tons per year will be produced just in the Jackson Purchase Area. One of the most efficient uses of this litter is as a nitrogen fertilizer source for corn.

Use Of Fluorogypsum To Reduce Subsoil Acidity In A Fragipan Soil, Grant W. Thomas, Gerald R. Haszler

Soil Science News and Views

In western Kentucky, there are several million acres of fragipan soils which are characterized by both acid subsoils and fragipans which commence at depths of 20 to 30 inches below the soil surface. The combination of subsoil acidity and a fragipan with massive structure impedes root growth and water movement, diminishing, somewhat, the usefulness of the soils for crop production. Alfalfa, a crop which is very sensitive to soil acidity and to poor drainage, was chosen as a test crop to measure the effects of adding fluorogypsum to Sadler silt loam, a soil representative of the fragipan soils found in …

Factors Affecting Crop Response To Liming, Kenneth L. Wells, J. L. Sims

Soil Science News and Views

Soil acidity levels directly affect the rate, kinds, and degree of chemical reactions which take place in soil. Crops respond to varying degrees to these chemical reactions. For the most part, these reactions affect the solubility of mineral elements in soil and the activity of the soil's biological processes. As a result, the availability of many plant nutrient elements is regulated by soil acidity. The level of availability of plant required nutrients can be adequate, deficient, or toxic to the plant, depending on the nutrient, soil acidity, and the crop. That is why measurement of soil acidity is regarded by …

Developing Efficient Crop Production Systems, Kenneth L. Wells

Soil Science News and Views

Land is initially the most limiting resource to consider in setting up a farm system aimed at maximizing returns. This is because soil, its topographical features, and its physical and chemical properties are largely fixed. There is little which can be done about them except to manage soil fertility and control erosion. Over the long run, crop production from any land tract will be directly influenced by the nature and character of the soils in that land tract. For this reason, the most basic step in initiating or redesigning a farming operation is to get an evaluation of the soil …

Geology And Stratigraphy Of The Western Kentucky Coal Field, Stephen F. Greb, David A. Williams, Allen D. Williamson

Bulletin--KGS

The Pennsylvanian rocks of the Western Kentucky Coal Field produce between 40 and 55 million tons of coal a year from as many as 45 coal seams; however, three seams produce more than 75 percent of the total. In addition, Pennsylvanian strata contain numerous oil and natural gas reservoirs, tar-sand reservoirs, and industrial minerals. Pennsylvanian sandstones are also some of the most important bedrock aquifers in the coal field. Because of the economic importance of the Pennsylvanian strata to the region and the Commonwealth as a whole, a better understanding of these rocks is needed. This description of the nomenclature …

Low-Silica And High-Calcium Stone In The Newman Limestone (Mississippian) On Pine Mountain, Letcher County, Southeastern Kentucky, Garland R. Dever Jr., Thomas L. Robl, Jack R. Moody, Frank H. Walker, George W. Ellsworth Jr., Lance S. Barron

Information Circular--KGS

The coal industry of Kentucky is an important market for limestone. Coal producers use limestone as rock dust for explosion abatement in underground coal mines and as a neutralizing agent in surface-mine reclamation and acid-drainage control. Haulage-road construction and maintenance require crushed stone.

Coal-bearing rocks of Pennsylvanian age in the Eastern Kentucky Coal Field generally do not contain limestones that are sufficiently thick to quarry or mine economically, but in the southeastern part of the coal field, fault movement has brought the Newman Limestone to the surface along Pine Mountain. The Newman was sampled at three sites in Letcher County …

Map and Chart--KGS

Highway roadcuts along Interstate Highway 75 from Conway, Kentucky, to Jellico, Tennessee, expose Mississippian and Pennsylvanian rocks in south-central Kentucky (Fig. 1). The roadcut exposures offer easy access and stratigraphic variety for educational purposes, and are ideal for high school, university, and professional geology field trips. Several national and international field trips, and many out-of-State university field trips have examined these exposures. In addition, scientific studies involving elastic and carbonate sedimentology, coal geology, paleontology, biostratigraphy, and karst (cave) development have been undertaken along this road.

Design, Construction, And Monitoring Of The Ground-Water Resources Of A Large Mine-Spoil Area: Star Fire Tract, Eastern Kentucky, David R. Wunsch, James S. Dinger, Page B. Taylor

Report of Investigations--KGS

By the year 2010, the Star Fire mining operation in Knott, Breathitt, and Perry Counties in eastern Kentucky, which uses mountaintop-removal and hollow-fill mining techniques, will have created approximately 5,000 acres of gently rolling terrain that could support alternative land uses. The present research is centered on approximately 1,000 acres of spoil created since mining began in 1981. An aquifer fed by both ground and surface water will be created within the spoil. Spoil-handling techniques such as cast blasting, dragline placement, end dumping by trucks, and surface grading have created porous coarse-rock zones within the spoil through which ground water …

Pavement Deflection Evaluations, R. Clark Graves, David L. Allen

Kentucky Transportation Center Research Report

In this study a procedure has been developed to evaluate the structural condition of pavements using Road Rater deflection measurements. These procedures compare actual field deflections with deflections calculated by the Chevron N-Layer linear elastic computer program. The results obtained from these procedures are the layer moduli of the pavement materials. Procedures have been developed for asphaltic concrete pavements and composite pavements, including broken and non-broken concrete layers. This report also contains a comparison of structural overlay determined using the results of the new procedure, with overlays calculated using results from the 2-3 Projected procedure currently used by the Pavement …

Row Cleaners In No-Till Corn, Lloyd W. Murdock, James H. Herbek, Tim Gray

Soil Science News and Views

Row cleaners are planter attachments mounted in front of the double-disc openers on planters. They are designed to move most of the surface residue to the sides of the row, allowing no-till planting into a band with a fairly clean surface. This attachment is best suited for wet, cool soils to allow a more rapid warming of the soil surface, on rough soil to allow some smoothing before planting, and in heavy residue to prevent "hairpinning" of residue into the planting slot. There is evidence that cleaning the residue from the row raises soil temperatures which results in quicker corn …

Geologic Highway Cross Sections: Interstate Highway 64 Farmers To Catlettsburg, Kentucky, Donald R. Chesnut Jr.

Map and Chart--KGS

Highway roadcuts along Interstate Highway 64 from Farmers to Catlettsburg, Kentucky, provide scientifically significant exposures of rocks of Devonian, Mississippian, and Pennsylvanian ages in northeastern Kentucky. The roadcut exposures offer easy access to a variety of stratigraphic units and are ideal for educational field trips. However, Kentucky law prohibits vehicles from stopping on the shoulders of limited- access highways except in case of emergency, so any planned field trips must be coordinated with State authorities. Several national and international field trips, as well as many out-of-State university field trips, have examined these exposures. In addition, scientific studies involving carbonate sedimentology, …

Stratigraphic And Structural Framework Of The Carboniferous Rocks Of The Central Appalachian Basin In Kentucky, Donald R. Chesnut Jr.

Bulletin--KGS

A series of seven cross sections across the Central Appalachian Basin in Kentucky, Tennessee, Virginia, West Virginia, and Ohio was constructed in order to determine a stratigraphic and structural framework of the Carboniferous rocks for the basin. Oil and gas well logs, coal-company core descriptions, measured sections, and mapping of surface geology were used to construct these sections. New surface and subsurface faults, folds, and flexures were identified.

New, formal and informal lithostratigraphic nomenclature was introduced to clarify the stratigraphic framework. Formalized nomenclatural changes are (1) elevating Breathitt Formation to Breathitt Group, (2) dropping the Lee Formation, (3) elevating four …

Available Coal Resources Of The Booneville 7.5–Minute Quadrangle, Owsley County, Kentucky, Gerald A. Weisenfluh, R. E. Andrews, John K. Hiett, Stephen F. Greb, Richard E. Sergeant, Donald R. Chesnut Jr.

Information Circular--KGS

The Booneville Quadrangle lies within the Southwestern Reserve District of the Eastern Kentucky Coal Field. Six coal beds in the quadrangle have been commercially developed, mainly by surface mining methods, and comprise the basis of this Coal Availability Study. These beds are, in descending stratigraphic order, Copland, Whitesburg, Amburgy, Upper Elkhorn No. 3, Jellico and Manchester. A computerized Geographic Information System (GRASS) was used to calculate estimates of original, mined-out and remaining resources, restrictions to mining and available resources.
