Current Challenges Can Help Fuel Future Opportunities, Jeffrey J. Steiner

Agricultural Research Magazine

Native juniper trees and invasive plants pose an expanding threat to the survival of the sagebrush ecosystem in arid western rangelands. As the trees mature, they compete with other native plants that are valuable food sources for wildlife and cattle. After these plants die back, the bare patches of soil that remain are vulnerable to erosion and encroachment from other species like cheatgrass, an invasive nonnative annual that fuels wildfires.

Wildfires threaten livestock ranches, are suppressed in large part by efforts funded with taxpayer dollars, and increase the probability that invasive plants will spread and thrive in the postfire landscape. …

Better French Fries: Technique Helps Lower Fat, Zhongli Pan, Marcia Wood

Agricultural Research Magazine

No doubt about it. Americans love French fries.

But fries soak up a lot of oil while they’re turning a perfect golden brown in the deep-fat fryer.

Agricultural Research Service scientist Zhongli Pan and colleagues have tackled the challenge of lowering some of the fat from this favorite side order without skimping on the fries’ delicious taste and texture or their pleasing appearance and aroma. Their idea? After potatoes are peeled and sliced into strips, and just before the raw strips are dunked in the fryer, prep them with 3 minutes of infrared (IR) heat—just like that created in home …

Fungi Can Be Friends Or Foes, Amy Rossman, Jo Anne Crouch, Shannon Dominick, Sharon Durham

Agricultural Research Magazine

Fungi are a large and diverse group of organisms. Some fungi, like mushrooms, are edible and considered crops. Others, however, can cause serious diseases of crop and forest plants, and those diseases can have negative effects on local and international economies as well as on the supply of food and other materials that agriculture provides.

The Agricultural Research Service maintains a unique resource—the U.S. National Fungus Collections—for helpful and detailed information about fungi. Accurate knowledge of fungi is critical for controlling the diseases they cause.

Measuring The Feeding Behavior Of Livestock, T. M. Brown-Brandl, Roger A. Eigenberg, Sandra Avant

Agricultural Research Magazine

Determining how much time animals spend eating could help animal caretakers identify sick livestock, improve management, and establish genetic differences within a herd. But first, a system is needed to monitor animal feeding behavior.

Scientists at the Agricultural Research Service’s Roman L. Hruska U.S. Meat Animal Research Center in Clay Center, Nebraska, have developed a new system to monitor feeding behavior of feedlot cattle and grow-finish swine in a livestock industry setting.

The system, created by agricultural engineers Tami Brown-Brandl and Roger Eigenberg in the center’s Environmental Management Research Unit, uses standard radio-frequency identification technology designed around a commercial reader. …

New, Improved Codling Moth Lures Available, David Nicholson, Jan Suszkiw

Agricultural Research Magazine

New lures that entice codling moths with the scent of food and a possible mate are available for use in monitoring this orchard pest and controlling it with carefully timed applications of insecticide. The research related to the development and use of the lures involved scientists Alan Knight and Peter Landolt at the Agricultural Research Service’s Yakima Agricultural Research Laboratory in Wapato, Washington, and Douglas Light at the ARS Western Regional Research Center in Albany, California.

As larvae, codling moths are major pests of apples, pears, and walnuts. Historically, growers have sprayed their orchards with insecticide to prevent the pinkish-white, …

Better Maps Mean Better Rangeland Management, Brandon Bestelmeyer, Ann Perry

Agricultural Research Magazine

Land managers are always hoping for the next best thing to help them figure out where they should spend their time and money restoring and maintaining healthy rangelands. Now Agricultural Research Service rangeland ecologist Brandon Bestelmeyer has one of the answers—an ecological-state map that identifies where rangeland is holding its own, where it could respond to restoration efforts, or where it’s already past the point of no return.

“We wanted to find a way to turn existing field-level rangeland assessments into broader tools for comprehensively managing larger landscapes,” says Bestelmeyer, who works at the ARS Jornada Experimental Range in Las …

New Strawberry Species Found In Oregon, Kim E. Hummer, Sharon Durham

Agricultural Research Magazine

A recently discovered wild strawberry species provides new genetic material for plant research and, in the future, might also provide a new class of commercial strawberries.

Agricultural Research Service scientist Kim Hummer, with the USDA-ARS National Clonal Germplasm Repository at Corvallis, Oregon, found the new species during several plant collection expeditions in the high peaks of Oregon’s Cascade Mountains. She named it Fragaria cascadensis.

The find was reported in the Journal of the Botanical Research Institute of Texas.

The new strawberry is endemic to the Oregon Cascades, hence its specific name, F. cascadensis. It is perennial, with …

Turning Trees Into Fighter Fuels, Ann Perry

Agricultural Research Magazine

In western U.S. rangelands, native juniper and pinyon pine trees are spreading beyond their historical ecological niches and disrupting the environmental balance of their expanded range. Meanwhile, Agricultural Research Service scientists are teaming with university and industry colleagues to turn this problem into a source of fuel for U.S. Navy fighter jets.

“Juniper competes with grass and forbs for water and nutrients, and this leaves bare soil that is vulnerable to erosion,” says ARS scientist Mark Weltz, who works at the Great Basin Rangelands Research Unit in Reno, Nevada. “We have also lost habitat for sage grouse and mule deer, …

Tools For Tracking Troublesome Trees, Kirk Davies, Matt Madsen, Ann Perry

Agricultural Research Magazine

In Oregon, western juniper trees are expanding their range, pushing out other plant species, reducing sagebrush habitat and livestock forage, and at times fueling catastrophic wildfires. During some of these conflagrations, fires burn even hotter because more wood is available to feed the flames—a cause-and-effect that in turn lengthens the time that temperatures remain elevated at fire-stricken sites.

To help streamline efforts to manage invasive trees, Agricultural Research Service rangeland scientists Kirk Davies and Matt Madsen are investigating ways of combining aerial photography and computer programs to quickly identify and measure affected areas. These tools could save time and money …

Savvy Seed Sorter Gains New Fans, Thomas C. Pearson, Marcia Wood

Agricultural Research Magazine

Simple, swift, and comparatively inexpensive, a color-image-based seed sorter is helping plant breeders and others separate the seeds they want from those they don’t—with an impressive degree of accuracy.

Agricultural Research Service agricultural engineer Thomas C. Pearson, based at the agency’s Center for Grain and Animal Health Research in Manhattan, Kansas, developed the sorter in collaboration with National Manufacturing in Lincoln, Nebraska. The company has marketed the device to customers in the United States and abroad since 2010.

In tests, the compact, portable sorter— a simpler and faster version of other machine-vision equipment that Pearson developed in 2009—speedily differentiated kernels …

Providing More—And Better—Food By 2050, John W. Finley

Agricultural Research Magazine

The world in 2050 is predicted to have 9 billion people, who will differ in almost every way but one: They will all need to eat on a daily basis.

Their nutritional needs will be similar, too. Nutrition means eating, eating means food, and food means agriculture. Many people speak of the increased food needed for 9 billion, but in reality, the increased need is for nutrition. Thus, the world of 2050 will force a melding of two disciplines that have diverged in recent years—agriculture and nutrition.

We need to change our focus. We need sustainable nutrition as much as …

Though the price makes you wince, you might just buy that bottle of your favorite olive oil anyway. Perhaps it’s exactly what you want for the salad dressing you’re making tonight and for your special stir-fry on the weekend. But are you really getting what you paid for?

A bottle proclaiming that it is olive oil might actually include another, lessexpensive vegetable oil derived from, for example, safflower or canola. Mislabeling is of concern not just to shoppers, retailers, and chefs, but also to America’s olive growers, olive oil processors, and more—especially those newly entering the U.S. olive oil market. …

Mapping The Way To Even Healthier Rice, Shannon Pinson, Jan Suszkiw

With the aid of high-tech tools, Agricultural Research Service and collaborating scientists are closing in on the genes in rice that regulate the uptake and storage of important minerals—a pursuit that could bolster the nutritional value of this cereal grain crop as a staple food for roughly half the world’s population.

Ultimately, the team envisions biofortifying rice using traditional plant breeding methods to develop new varieties whose kernels (grain) boast exceptionally high concentrations of essential minerals, including zinc, iron, and calcium.

Rice is a mainstay of the human diet for good reason. It is a rich source of energy, free …

Nematode-Filled Capsules Tested Against Corn Rootworms, Jan Suszkiw

Agricultural Research Magazine

Each spring, the western corn rootworm (Diabrotica virgifera) awakens from its winter slumber to wreak havoc on corn crops across the United States. The pest emerges in larval form, hatching from small white eggs deposited beneath the soil and causing significant feeding damage to the grain crop’s roots. The toll on U.S. farmers: an estimated $1-2 billion annually in yield losses and chemical control.

European growers face a similar threat from the pest, which was first reported in a corn field near the Belgrade international airport in Serbia (formerly Yugoslavia) in 1992, but is presumed to have arrived …

Getting Hooked On Farmed Salmon: A Good Source Of Omega-3s, Susan Raatz, Matthew Picklo, William Wolters, Rosalie Marion Bliss

Nearly 85 percent of seafood enjoyed by U.S. consumers is imported, and almost half of that is farm raised through a process called “aquaculture,” according to the National Aquaculture Association, based in Pine Bluff, Arkansas. In 2011, the United States imported $16.6 billion of seafood and exported $5.4 billion, a difference of $11.2 billion.

As the world’s population grows and demand for seafood increases, many seafood species are overfished or fully exploited. That means the world’s oceans cannot turn out more fish than are currently being produced. As the ceiling is being reached on seafood availability from the wild, U.S. …

Dogs, Pine Trees, And Carbs, Neil P.J. Price, Marcia Wood

Agricultural Research Magazine

Carbohydrates from a perhaps surprising source—pine trees—may have beneficial effects on dogs’ digestive-system health, according to collaborative studies by Agricultural Research Service, university, and corporate scientists.

The carbs, predominantly a group known as “GGMOs”—short for galactoglucomannan oligosaccharides—are a key ingredient in Previda, an all-natural dietary ingredient marketed to makers of pet food, aquaculture feed, and other animal-nutrition products.

ARS chemist Neil P.J. Price began his studies of these fiber-rich carbs in 2007, working under the auspices of a cooperative agreement with Temple-Inland, a Texas-based producer of lumber, fiberboard, and other wood products made from loblolly, longleaf, and other kinds of …

Nourishing America’S Preemies Scientists Confront The Challenges Of Iv Feeding, Douglas G. Burrin, Marcia Wood

Agricultural Research Magazine

Each year, more than a half-million infants are born prematurely in the United States. Many of these preemies, particularly those whose tiny digestive systems are simply too underdeveloped to handle mother’s milk or infant formula, may need to be nourished exclusively via intravenous feeding, known as “total parenteral nutrition,” or TPN.

TPN solutions, usually administered at the hospital for anywhere from a few days to a month or more, provide essential nutrients broken down into a very basic form. This liquid is gently and continuously infused into the infant’s bloodstream, completely bypassing the digestive tract.
