A weed calculator developed by an Agricultural Research Service (ARS) scientist tells ranchers the number of additional cows they could raise if they eliminated one or two widespread exotic invasive weeds. Rangeland ecologist Matt Rinella at the ARS Fort Keogh Livestock and Range Research Laboratory in Miles City, Mont., created a computer model that predicts weed impacts on forage production. Data for developing the model came from 30 weed researchers working throughout the western United...

Two new compact oakleaf hydrangea cultivars ideal for small gardens have been released by Agricultural Research Service (ARS) scientists. "Ruby Slippers" and "Munchkin" are the latest cultivars released by ARS geneticist Sandy Reed with the U.S. National Arboretum's Floral and Nursery Plants Research Unit's worksite in McMinnville, Tenn. The arboretum is operated by ARS, the principal intramural scientific research agency of the U.S. Department of Agriculture (USDA). The new cultivars are the...

Agricultural Research Service (ARS) scientists are helping U.S. Nuclear Regulatory Commission (NRC) experts model the movement of radioactive materials in the soil. Their findings can be used to fine-tune the risk assessment studies that are an essential component in the development of commercial nuclear facilities. Soil scientists Yakov Pachepsky, Timothy Gish and Andrey Guber all work in the ARS Animal and Natural Resources Institute in Beltsville, Md. The team set up their study at the...

An Agricultural Research Service (ARS) scientist may have found a way to cut the amount of ammonia produced by cattle. To do it, he's using a key ingredient of the brewer's art: hops. Cattle, deer, sheep, goats and other ruminant animals depend on a slew of naturally occurring bacteria to aid digestion of grass and other fibrous plants in the first of their four stomach chambers, known as the rumen. The problem, according to ARS microbiologist Michael Flythe, comes from one group of bacteria,...

Incoming raw poultry is the primary source of Listeria monocytogenes contamination in commercial chicken cooking plants, according to a 21-month study conducted by Agricultural Research Service (ARS) scientists and their collaborators at the University of Georgia. The study's results will help these facilities more sharply focus their sanitation processes to reduce cross-contamination. L. monocytogenes is a bacterial human pathogen that is sometimes found in fully cooked, ready-to-eat...

Agricultural Research Service (ARS) scientists are figuring out how to turn wheat straw into ethanol "gold," and learning more about the bacteria that can "infect" ethanol plants and interfere with fuel production. At the ARS National Center for Agricultural Utilization Research (NCAUR) in Peoria, Ill., ARS chemist Badal Saha conducted a 5-year study that examined whether wheat straw"”a crop residue left over after the grain has been harvested"”could have commercial potential for...

Self-pollinating almond trees that can produce a bountiful harvest without insect pollination are being developed by Agricultural Research Service (ARS) scientists. This is good news for almond growers who face rising costs for insect pollination because of nationwide shortages of honey bees due to Colony Collapse Disorder (CCD) and other factors. ARS geneticist Craig Ledbetter, at the agency's Crop Diseases, Pests and Genetics Research Unit near Parlier, Calif., is developing this new line...

Tomorrow's fragrant bouquets and colorful potted plants might last longer, thanks to floriculture research by Agricultural Research Service (ARS) plant physiologist Cai-Zhong Jiang. His investigations might help boost the vase life of favorite cut flowers and shelf life of prized potted plants. Jiang is with the ARS Crops Pathology and Genetics Research Unit at Davis, Calif. He's collaborating with researchers from the University of California-Davis (UCD) and elsewhere. In ongoing studies,...

A unique collection of St. John's wort (Hypericum) curated by Agricultural Research Service (ARS) scientists in Ames, Iowa, is providing university collaborators with genetically diverse, well-documented sources of this herb to use in studies examining its medicinal potential. In collaboration with Mark Widrlechner, a horticulturist with the ARS crop genebank at the North Central Regional Plant Introduction Station in Ames, scientists from the Center for Research on Botanical Dietary...
