B Financial Statement .............................................................................................. 27 Staff ...................................................................................................................... 28 Purpose of the Kentucky Agricultural Experiment Station As a Land Grant institution, the University of Kentucky is responsible for serving the people of the Commonwealth of Kentucky. The College of Agriculture, with its research, teaching, and extension activities, has developed a structure and organization to provide the mandated Land Grant ser- vices in agriculture and related areas. The Kentucky Agricultural Experiment Station has been providing research results to farmers and rural residents for more than 100 years. The continued advancement of Ken- tucky agriculture attests to the benefits of applying new knowl- edge and technology. Much of the research leading to in- creased quantity and improved quality of Kentucky’s agri- cultural output was performed by the Experiment Station. College researchers also have successfully addressed prob- lems of agribusiness, consumers, international trade, food processing, nutrition, community development, soil and wa- ter resources, and the environment. Although much Experiment Station research has immedi- ate application to agricultural and natural resource-related problems, scientists are also involved in basic research, gen- erating new information to help solve present and potential problems. The ability of Kentucky producers to be competi- tive in domestic and world markets requires an expanded base of knowledge in emerging areas of research applicable to agriculture, food, and natural resources. This Annual Report lists Experiment Station research projects and publications completed during 1999. A faculty list is also provided. The research programs of the Kentucky Agricultural Ex- periment Station have benefited Kentucky’s agriculture over the past century, and the results of present and future re- search will continue to serve Kentucky’s primary industry. Statewide Research Research activities of the Kentucky Agricultural Experi- ment Station were conducted at Lexington, Princeton, Quicksand, and Owenton and in counties throughout the state in 1999. Efforts are constantly made to ensure that the research studies have application to the problems of all Kentucky farmers and other clientele groups. Locations of the experi- mental facilities provide conditions representative of most sections of the state. Campus—Laboratories and specialized equipment for all research program areas. Coldstream—Maine Chance—Spindletop Farms—Beef and dairy cattle, poultry, horses, sheep and swine, forages and grain crops, tobacco and turf. South Farm—Fruits and vegetables, omamentals. UKAnimal Research Center (Woodford County)——This farm was purchased in late 1991 as a location for develop- ment of state-of-the-art food animal research programs. The farm is in Phase I of development as a research facility. At Princeton (Caldwell County) the Research and Edu- cation Center facilities and the West Kentucky Substation Farm are devoted to research on grain crops, beef cattle, swine, fruits and vegetables, forages, and tobacco. At Quicksand (Breathitt County) the Robinson Station is the location of research on fruits and vegetables, omamentals, forages, grain crops, tobacco, and wood utilization. Quick- sand is also the headquarters of Robinson Forest, which spreads over parts of Breathitt, Perry, and Knott counties and is the site of forestry and watershed management research. At the Eden Shale Farm, located in Owen County near Owenton, experimental and demonstration studies are con- ducted on forage crops, tobacco, fruits and vegetables, and beef management. Regulatory Services The Division of Regulatory Services administers state laws pertaining to the manufacturing, processing, labeling, and marketing of commercial fwd, fertilizer, seed, and raw milk. Its purpose is to protect farmers and other consumers from poor quality, mislabeled, or misrepresented products and to pro- tect agricultural businesses from unfair competition from those who might take shortcuts in the quality of their products. Feed, fertilizer, and seed are monitored in the manufactur- ing or retail channels for reasonable and acceptable compli- ance with state laws through label review, product and facil- ity inspections, and product sampling and analysis. Raw milk is monitored during marketing to assure an accurate and eq- uitable exchange between producers and processor and to ensure the integrity of milk from farm to processor. Ten regulatory inspectors and one auditor cover the state, collecting samples, inspecting facilities, and auditing records. Additionally, a specialty-products inspector checks and samples small-package and specialty feed, fertilizer, and seed products throughout the state. The Division also offers to growers and homeowners seed testing, soil testing, poultry litter and animal manure testing, and water and nutrient solution analyses for greenhouse pro- duction and float-bed systems of seedling production. Auditing Program H.S. Spencer Audits of sales and fee payments were made on 3 14 of 546 milk seed, feed, and fertilizer businesses in Kentucky to verify check-off and tonnage fees. Fees assessed to help pay the costs of inspecting, sampling. and analyzing commodities in accordance with Kentucky laws are: fertilizer, 50 cents per ton; feed. 35 cents per ton; and seed, 4 to 24 cents per unit. During May, raw milk is assessed a check-off fee of 3 cents per 100 pounds. Income from fees in 1999: Feed .................................................................... $720, 728 Fertilizer ............................................................... 631,360 Milk ........................................................................ 61. 925 Soil testing ........................................................... 168,721 Seed tags. testing, and licenses ........................... 363,661 TOTAL $1,946,395 These cash receivables were substantiated on 2,612 fertilizer tonnage reports. 2.976 feed tonnage reports, 724 seed re- ports. and 15 milk reports. These reports were checked for accuracy and compared with field audits of the firms submit- ting them. Additional fees of $ 16,920 were found as a result of these audits. Milk Regulatory Program C .D. Thompson The milk regulatory program administers the Kentucky Creamery License Law and Regulations. The program’s pri- mary objective is to ensure the proper payment for milk pro- duced in Kentucky. These payments must be based on a series of accurate weights and tests. The program provides a market- place environment that is fair and equitable for all individuals and firms involved in the dairy industry. In 1999, the division: - reviewed and issued licenses to 14 milk buyers, 56 testers, 3 97 sampler-weighers, and eight raw milk transfer stations. - analyzed and administered action on 6,757 official samples. - analyzed 801 samples submitted by licensed testers for comparison purposes. - conducted 12 producer pay record audits. - conducted 56 inspections at 15 milk laboratories. - trained and examined 48 new sampler-weighers and 15 new testers, ~ conducted 653 inspections of 225 sampler-weighers. - conducted 36 inspections of raw milk transfer stations. Feed Regulatory Program Eli Miller The feed regulatory program provides consumer protec- tion for the purchasers of livestock feed and pet foods, main- tains a marketplace environment that promotes fair and equi- table competition for the feed industry, and helps ensure the safety and wholesomeness of animal products as human food. In 1999, the program: - administered actions on 4,83 9 official samples of commer- cial feed involving 27,994 ofiicial tests to monitor about 3 million tons of commercial mixed feed and feed ingredi- ents distributed in Kentucky. - administered a cooperative program with the FDA to in- spect two feed mills that mix restricted drugs in feed and to inspect seven feed mills for compliance with FDA’s national BSE regulation, which prohibits the feeding of certain mammalian proteins to cattle and other ruminants. An additional 63 state inspections were conducted on mills that mix non-MFA drugs in feed to ensure compli- ance with medicated feed regulations. Fifty-three mills that mix no drugs were inspected to ensure compliance with labeling, manufacturing, and storage practices. - conducted 7,500 label reviews and maintained product reg- istration for about 15,000 products from 900 companies. - continued implementation of the revised feed labeling re- quirements for livestock and poultry feeds. l— )— [— ls 5, )r Fertilizer Regulatory Program D.L. Terry The Kentucky Fertilizer Law ensures that fertilizers sold in Kentucky are clearly and accurately labeled so that con- sumers can make informed purchases of fertilizer and be as- sured of its quality. The law also protects the legitimate fertil- izer industry from unfair competition. In 1999, the program: ' administered actions on 3,856 official and 458 unofficial samples of fertilizer involving 13,361 tests of the approxi- mately one million tons of fertilizer distributed in Ken- tucky. - reviewed labels and registered 3,714 products from 543 firms, including 214 who manufactured custom blends of fertilizers. - conducted two bulk-blend workshops for the fertilizer in- dustry. Inspection Program F Herald The inspection program aims to achieve industry compli- ance with the consumer protection laws that the division is charged with administering. Inspectors strategically located throughout the state, each with an assigned area to cover, carry out this responsibility. They inspect manufacturing plants, processing facilities, storage warehouses, and retail stores; collect official samples of feed, pet food, fertilizer, milk, and seed; review records; and offer assistance to cli- entele in improving their operations to achieve compliance with the laws. In 1999: - A team of nine inspectors performed 5,205 inspections of the processing, manufacturing, and marketing of feed, fer- tilizer, and seed. They inspected eight feed mills for compli- ance with FDA’s regulation to prevent the establishment of bovine spongiform encephalopathy (BSE) in the United States. One inspector traveled throughout the state to in- spect and sample small-package and specialty feed, fertil- izer, and seed products in urban areas. Another inspector covered the state to administer the Creamery License Law. - Inspectors collected the following numbers of official Samples for laboratory verification of appropriate constitu- ents and quality: Feed ......................................................................... 4,839 Fertilizer ................................................................... 3,856 Seed ......................................................................... 2,981 Milk ......................................................................... 6,757 Seed Regulatory Program D. T Buckingham The seed regulatory program'assures Kentucky farmers and urban consumers of quality seed and promotes fair and equitable competition among seed dealers and seedsmen. In 1999, the program: - collected and tested 2,981 ofiicial seed samples. - issued stop-sale orders on 428 official seed samples and 229 violative seed lots at seed dealer and seed processor locations. - cooperated with the USDA-Seed Branch regarding ship- ments of seed into Kentucky that were in violation of the Federal Seed Act. - issued 237 permits to label seed and registered 373 seed dealer locations. Performed inspections and sampling of agricultural, lawn, turf, and garden seeds during 1,854 vis- its to more than 600 wholesale and retail locations. Seed Testing Services E.E. Fabrizius The seed testing program provides the seed industry and seed growers of Kentucky with competent, reliable, and timely analyses of their seeds for labeling requirements and quality assurance. In 1999, the seed laboratory tested the following number of samples: Ofiicial seed samples (regulatory) ........................... 2,981 Regular seed samples (service) ............................... 3,551 Certified seed samples (service) ................................. 283 Tobacco seed samples (service) .............................. 1,506 TOTAL .................................................................... 8,321 In addition to routine testing for purity, germination, and noxious weed seed, the laboratory offers testing for seed vigor (accelerated aging and cold test), seed moisture, seed size (seed count), and germination following fungicide appli- cation. The laboratory also provides tests to seedsmen and livestock farmers for the presence of the fungal endophyte in tall fescue seed and live fescue tillers. Soil Testing Service El. Sikora (Lexington); D.L. Kirkland (UKREC, Princeton) Soil testing provides farmers, homeowners, greenhouse op- erators, surface-mine specialists, and others with scientific in- formation about the fertility status of their soils. In partnership with the Cooperative Extension Service, it also provides them with lime and fertilizer recommendations based on soil tests. We also offer analyses of poultry litter and animal wastes for farmers and farm advisors, water and nutrient solution analyses to green- house operators and float-bed seedling producers, and non- routine soil tests for University of Kentucky researchers. Samples analyzed in 1999 were: Type Number % Increase Agriculture ......................... 32,921 ............................... -4 Home lawn and garden ........ 6,133 ............................... -l Snip-mine reclamation ................ 0 ............................ -100 Commercial horticulture .......... 610 .............................. 19 Greenhouse ................................ 0 ............................ -100 Research ............................. 1 1,775 ............................. -35 Atrazine residue in soil ............. 65 ............................. -56 Animal waste .......................... 848 ............................. 568 Nutrient solution ..................... 256 ............................... 22 TOTAL .............................. 52,608 ............................. -12 Kentucky Agricultural Experiment Station Projects Agricultural Economics Agricultural Industrialization and Globalization: Implications for Ru- ral Economies—S.
