Illinois farmers planning to apply limestone to their fields
can consult a free publication from the Illinois Department of
Agriculture to make sure that they are applying at the appropriate
rate. The Illinois Voluntary Limestone Program Producer Information
Book lists the Calcium Carbonate Equivalent and a correction factor
for limestone from each supplier that takes part in the program.
"The information in the Limestone Book is very important
for producers who want to make the most effective application
possible on their fields," said Mark Ringler, Bureau Chief
of Agricultural Products Inspection for the Illinois Department
of Agriculture. "Not all limestone is the same, so this information
is designed to let the producer know how much limestone from a
particular quarry needs to be applied to meet the needs of their
fields." If a farmer is instructed to apply one ton of limestone
per acre to neutralize acidity, but he purchases from a source
with a listed correction factor of 1.5, the producer would need
to apply one and a half tons per acre.
The Limestone Book is produced annually through the cooperation
of the aggregate producers, the Illinois Department of Transportation
and the Illinois Department of Agriculture. Limestone samples
collected by the Department of Transportation are tested by the
Department of Agriculture. The Limestone Book is available on-line
or by calling 217-785-8349.
New Virus Test Kit Helps Keep Chicken on the Dinner Table
Don Comis, ARS News Service, USDA, (301) 504-1625, firstname.lastname@example.org
A new commercial blood test kit based on Agricultural Research
Service technology detects chicks infected by an extremely virulent
strain of avian leukosis virus, ALV-J. It is the first commercial
product to result from an emergency ARS response to an ALV-J emergence
in the United States that reached epidemic proportions in 1996.
The epidemic produced shortages of breeding stock that threatened
the poultry industry's ability to meet the burgeoning demand for
chicken on the dinner table.
The new ALV-J kit, made by Synbiotics Corp. of San Diego, Calif.,
is one of two such kits in the world. The other kit was developed
through a similar response by researchers abroad. To meet this
worldwide threat, ARS works with scientists throughout the world
as part of an ever-expanding consortium of private industries,
universities and government agencies. The U.S. Primary Breeders
Veterinary Roundtable has funded some of the ARS research as part
of its long-term reliance on ARS for industry-sustaining research.
Biochemist Lucy Lee, at the ARS Avian Disease and Oncology Laboratory
in East Lansing, Mich., (www.msu.edu/~arsadol) made this kit possible
by finding a way to isolate and clone the gene that produces the
protein coat that protects the live virus. Chicken cells react
to the coating because that is the first thing they detect when
the virus invades. The U.S. Department of Agriculture has patented
Lee's techniques. ARS is the chief scientific research agency
of USDA. Breeders can use the kits to reduce ALV-J infection.
They can take blood samples from chicks to see if the chicks have
antibodies indicating exposure to ALV-J. Lee and other researchers
in the United States and abroad are using the gene for research
in developing an ALV-J vaccine.
ALV cannot infect people or animals besides chickens and has
largely been found in the birds raised by primary broiler breeders,
the birds that are the parents of the birds we eat.

University Extension Service. It was funded through an NRCS EQIP
grant to develop materials based on the Farm*A*Syst/Home*A*Syst

Judicious Use of Antimicrobials in Food Animals Videos
The Food and Drug Administration's Center for Veterinary Medicine,
in conjunction with AVMA, has produced educational materials on
the judicious use of antimicrobials in food animals. These include
two videos and booklets, "Keeping Up Our Guard" (designed
for veterinarians) and "Safeguarding America's Health"
(designed for livestock producers), and four booklets for veterinarians
on judicious use of antimicrobials in swine, beef cattle, dairy
cattle, and poultry. For more information contact: Beth Karp,

Biodiversity of Illinois, Volume III: Prairie and Edge
The new Biodiversity of Illinois, Volume III: Prairie and Edge
Habitats CD-ROM is the third and final installment in the Biodiversity
of Illinois series of CD-ROMs from the Illinois Department of
Natural Resources' Division of Education. Prairie and Edge Habitats
is designed to provide supplemental information about Illinois
prairie and edge species and habitats for the educator and student.
It contains 505 Illinois prairie and edge species representing
mammals, birds, reptiles, amphibians, fishes, arthropods, flatworms,
roundworms, flukes, plants, fungi, protists and bacteria. Species
are accessible in a field guide format.
Along with the photographic images, each individual species screen
offers information about features, behavior, habitat, Illinois
range, sounds (if available), classification and status (endangered/threatened;
native/exotic). The sounds produced by 90 species are available
for the listener. Descriptions and photographs of Illinois prairie
and edge habitats are included on the CD-ROM. A section on biodiversity,
what it is and why it is important, is available as are resources
and references and an explanation of scientific names. Prairie
burning is discussed and illustrated in the biodiversity section.
The CD-ROM is searchable. The CD-ROM runs on both Windows and
Macintosh operating systems. Funding Biodiversity of Illinois,
Volume III: Prairie and Edge Habitats was provided by the Illinois
Department of Natural Resources, the Illinois Chapter of The Nature
Conservancy and the Lake County Forest Preserves. Funding was
administered by the Illinois Conservation Foundation. The Biodiversity
of Illinois series of CD-ROMs was developed for grades five through
