In Wyoming, about $4 million worth of rangeland cattle and sheep were lost to predators in 2005. Using a computerized model, researchers have now simulated an individual ranch’s economic impact of livestock losses to predators such as wolves and coyotes. Both short-term profitability and long-term viability were found to be affected by predation.

Potatoes come in all shapes, sizes and colors-including tubers with red, yellow, orange and purple flesh. This diversity also applies to phytonutrients, Agricultural Research Service (ARS) scientists in Prosser, Wash., are discovering.
Conventional wisdom has long held that grazing livestock on rangelands in good to excellent condition is the most productive, both ecologically and economically. However, ranchers generally maintain a lower level of range condition and neither profitability nor sustainability have been negatively affected.
Study finds benefits of cover crops in preventing soil erosion in the winter and the following year when compared to rough tillage

A team of scientists estimated net global warming potential for three grazing management systems located in central North Dakota. The results indicate that grazinglands are strong sinks of soil organic carbon and minor sinks of methane, but small to moderate sources of nitrous oxide.
New book chapter highlights critical agricultural research areas receiving federal funding, including food, nutrition, and natural resource sciences.
Algae--already being eyed for biofuel production--could be put to use right away to remove nitrogen and phosphorus in livestock manure runoff, according to an Agricultural Research Service (ARS) scientist.
A North Carolina State University study shows that out-of-work agricultural laborers from small farms that do not provide unemployment insurance spend fewer weeks unemployed and then earn less than other workers when rehired.
Using herbicides to sterilize rather than to kill weedy grasses might be a more economical and environmentally sound weed control strategy, according to a study by Agricultural Research Service (ARS) scientists and a cooperator.
Stem canker caused by a fungus, can severely create losses in soybean crop yield. Midwestern and north central regions of the United States and Ontario, Canada were plagued by the northern fungus in the late 1940s and early 1950s that was eradicated. Southern stem canker arose in the 1970s and continues to be a significant problem. The northern fungus now appears to have returned.
