The Role In Alfalfa In Soil Conservation, Glenn D. Johnson

Kentucky Alfalfa and Stored Forage Conference

Due to its many benefits, alfalfa has earned its reputation as "Queen of the Forages". Some of alfalfa's advantages are 1) very high nutritional value for all classes of livestock, 2) adaptability to a wide range of soils and growing conditions, 3) flexibility in being able to be grown alone or with grasses, 4) to be harvested for hay, silage or pasture, 5) strong seedling vigor and 6) high yields.

Alfalfa also should be rated "Queen of the Forages" as a crop for the soil. In addition to its many other benefits, alfalfa is an excellent choice for soil improvement …

1990 Kentucky Red Clover Variety Test, L. M. Lauriault, Norman L. Taylor, Jimmy C. Henning, W. T. Edmonson

Agronomy Notes

Red clover is a high quality, shortlived perennial legume that is used in mixed or pure stands for pasture, hay, silage, green chop, and soil improvement. This species is adapted to a wide range of climatic and soil conditions and therefore is very versatile as a forage crop. Stands are generally productive for two or three years with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures. It is the dominant legume in Kentucky because it is high in seedling vigor, quality, yield, and animal acceptance.

Fall Fertilization And Liming For Tobacco Production, J. L. Sims, Kenneth L. Wells

Soil Science News and Views

Proper nutrition of tobacco is a prerequisite for achieving high yields of cured leaf possessing desirable marketing characteristics. Together with the variety grown, soils, climate, and curing conditions, a desirable nutrient environment greatly influences yield, quality, and usability of the leaf produced. Late summer and early fall is a good time to select fields for future tobacco crops or to sample this year's tobacco fields which will be used for tobacco next year, and to assess their needs for lime, phosphorus, and potassium. Planning fertilization strategies this fall that lead to increased profit is much more effective than waiting until …

Response Of Soybeans To Available Potassium In Three Kentucky Soils, John H. Grove, William O. Thom, Lloyd W. Murdock, James H. Herbek

Agronomy Notes

Soybeans are produced in nearly all of Kentucky's soil physiographic regions. Soybean response to potassium (K) fertilization and soil test Kvaries with soil type and location. This variation may be associated with the wide range in soil chemical and mineralogical properties among the different regions. Of particular interest are differences in that level of soil test Kat which no further yield response to K fertilizer application would be expected. The main objective of this work was to evaluate the soil K-soybean response relationship on three different field sites where soybean yields were increased by fertilizer K. Several measures of soil …

Hay Additive Review: "Where We've Been, Where We're Going", William C. Mahanna, Steve Soderlund

Kentucky Alfalfa and Stored Forage Conference

The losses from harvest to feed bunk are undoubtedly greater with hay than any other crop grown by the American farmer. The economic implications of reducing losses through improved harvest technologies is staggering when one considers the 75-85 million tons of alfalfa harvested out of the total 140-145 million tons of hay produced annually in the United States.

Alfalfa Producers: Do You Really Know How Good Your Alfalfa Is? Forage Analysis: Importance And Interpretation, Jimmy C. Henning

Kentucky Alfalfa and Stored Forage Conference

Forages make up over 75% of the diet of all cattle and are the basis of cow-calf industry in the midwest. However, a recent survey of over 1000 livestock producers in Missouri revealed that only 5.6 % had ever had their hay tested. They gave several reasons for why they had not tested hay (Table 1). By a large margin, the greatest reason for not testing was that they did not see a need. This fact highlights the purpose of this paper and presentation at the 10th Annual Kentucky Alfalfa Conference. This paper will explain the terms used in …

Beef Cattle Production On Surface-Mined Land In Central Appalachia, William O. Thom, H. B. Rice, David Adams, Charles May, Curtis Absher

Agriculture and Natural Resources Publications

Extensive acreages of reclaimed surface-mined land in Central Appalachia are currently producing forages that can be used in beef cattle production. During reclamation, after these areas were graded, they were seeded with grass and grass-legume mixtures to form a ground cover and to reduce soil loss. Usually in the past these areas have not been managed to provide forages for beef cattle, but they can economically support beef cattle production when managed correctly.

Lead In Your Drinking Water, Joseph L. Taraba

Agricultural Engineering Extension Updates

The U.S. Environmental Protection Agency (USEPA) recently imposed a regulation requiring public water suppliers to notify all their customers of the potential health effects of lead from household plumbing. The USEPA regulates public water supplies (with at least 15 service connections or servicing 25 individuals) but does not regulate private water supplies. The potential health hazard of lead is also present from household plumbing which is supplied water from a private water source.

The Effect Of Preozonation On The Anaerobic Biodegradability Of Resistant Phenolic Compounds, Yi-Tin Wang, Pin-Chieh Pai, James L. Latchew

KWRRI Research Reports

Ozone pretreatment studies of four model phenolic compounds were conducted to evaluate the effects of ozonation on the anaerobic biodegradability and toxicity of these compounds. Two types of batch studies, the Biochemical Methane Potential (BMP) and the Anaerobic Toxicity Assay (ATA), were performed on samples ozonated upon phenol, o-cresol, 2,5-dichlorophenol, and 2,4-dinitrophenol.

Experimental results showed that toxic and refractory phenolic compounds were converted to methane gas by means of preozonation. In general, the biodegradable fraction of the oxidation products increased as the ozone dose was increased. However, ozonation to achieve at least 60% COD reduction was necessary to faciliate methane …

Feeding Young And Growing Horses, Equine Section, Department Of Animal Sciences, University Of Kentucky

Agriculture and Natural Resources Publications

When you plan a feeding program for your young horses, several factors are very important:

• body changes involved in growth,
• nutrient requirements of that particular class of horse,
• the feed’s nutrient content,
• anatomical limitations of young horses’ digestive system, for instance, you cannot feed young horses low-energy, bulky feeds because their digestive tracts are not large enough. Instead, young horses need concentrated sources of energy, protein, vitamins and minerals to meet their nutritive needs.

Evaluating Hay Quality, William C. Templeton Jr.

Kentucky Alfalfa and Stored Forage Conference

One of the frustrations to nutritionists interested in the feeding value of roughage has been that with all their book knowledge and technical aids no dependable scheme they could devise would consistently rank forages in feeding value, while the dumb ruminant animal could unerringly detect differences in their nutritive values.

The Stallion: Breeding Soundness Examination & Reproductive Anatomy, Equine Section, Department Of Animal Sciences, University Of Kentucky

Agriculture and Natural Resources Publications

A breeding soundness exam of a stallion includes not only examination of various seminal characteristics, but also, the evaluation of the stallion’s physical condition and his ability to perform in the breeding shed. The physical examination should include evaluation of the locomotor system, including muscular, skeletal and neurological factors, as well as the stallion’s visual function.

The most reliable measure of fertility in a stallion is the pregnancy rate he obtains when bred to mares of normal fertility under ideal management. Most stallions selected for evaluation include those about to be, or recently, purchased, those about to enter the breeding …

Nutrition Of The Performance Horse, Equine Section, Department Of Animal Sciences, University Of Kentucky

Agriculture and Natural Resources Publications

In today’s industry where seconds mean the difference between 1st and “also ran” at the track, our equine athletes must retain a competitive edge. Renewed interest in research about the performance horse’s nutrient needs has allowed horsemen to feed the athletic horse more scientifically than ever before to maintain that edge. Horses can be selected, bred, managed and fed as athletes. However, because knowing the horse’s individuality and nutrient needs is very important, the horseman’s skill in feeding the horse will never be totally replaced, no matter how precise the feeding recommendations.

Nutrition Of The Broodmare, Equine Section, Department Of Animal Sciences, University Of Kentucky

Agriculture and Natural Resources Publications

Feeding horses has long been considered an art passed down from generation to generation. However, recent advances are rapidly making horse nutrition a more precise science. Research in horse nutrition has provided valuable information on the nutrient needs of all classes of horses.

In feeding broodmares, you must consider several important factors:

• nutrient requirements of the particular class of horse being fed,

• physiological events involved in pregnancy,

• nutrient content of the feed,

• physiological limitations to certain rations.

Soil Microbes And Biotechnology, M. Scott Smith

Soil Science News and Views

There is nothing new about attempts to develop and market microbial products for crop or soil improvement. Several types of microbes have been sold for a variety of agronomic purposes for many years. With the important exception of rhizobial inoculants. these have been generally unsuccessful. Recently however. the scientific revolution in genetics and molecular biology, the need for low cost agronomic inputs. and widespread concern for environmental safety have tremendously stimulated research and commercial activity on microbial products. Claims that cheap, effective microbial inoculants can be developed for pest control, detoxifying pollutants, providing plant nutrients and improving soils have been …

1987 Update Of Agronomic Performance Of Tall Fescue Varieties, Paul B. Burrus Ii, Garry D. Lacefield, J. Kenneth Evans

Agronomy Notes

Tall fescue (Festuca arundinacea, Schreb.) is a well adapted, widely used pasture species occupying approximately 5.5 million acres in Kentucky and 35 million acres in the south central United States.

Commercial tall fescue varieties have been developed from plant materials of either northern European or Mediterranean origin. Varieties developed at the University of Kentucky -- Kentucky 31, Kenmont, Kenwell, Kenhy, and Johnstone -- trace to plant materials of northern European origin. The Kentucky varieties have later maturity dates and have greater resistance to certain foliar diseases during summer than varieties that are of Mediterranean origin (i.e., Alta, Fawn, Goar, and …

Effect Of Fertilizer Rates And Placement Practices On Yield Of Burley Tobacco, Kenneth L. Wells, G. D. Cantrill, J. L. Sims

Agronomy Notes

Management of fertilizer practices in production of burley tobacco is very important in control of manganese (Mn) toxicity of the crop. In addition to the use of agricultural limestone, the use of fertilizers in the appropriate amounts, the appropriate kinds, and in the appropriate manner can strongly influence acidity in the rooting zone during the growth of burley. Studies of these effects have made up a major thrust of the University of Kentucky's research programs on fertility of burley, and have largely been conducted by J.L. Sims and his students during the past 15 years.
