Robust Results From Long-Term Research On Organic Cover Cropping, Eric Brennan, Ann Perry

Agricultural Research Magazine

“We can obtain important results from short-term field studies, but they don’t always capture year-to year variability. Long-term research often provides more reliable results that farmers need,” says Agricultural Research Service horticulturist Eric Brennan.

Brennan speaks from personal experience. In 2003, he and a team of University of California-Davis collaborators began a 2-year field study that evolved into a unique long-term investigation of high value organic cropping. The project, the Salinas Organic Cropping Systems trial, is being conducted on an ARS research farm and is now in its 10th year of certified organic production. Brennan, who works in the ARS …

New Tools For Studying The Root Of The Matter, Leon V. Kochian, Dennis O’Brien

Agricultural Research Magazine

Like any structure, a root has its own architecture. Some roots burrow straight down into the soil. Others scatter web-like tentacles. However they turn out, root systems play a critical role in the health and survival of today’s crops. That’s why Agricultural Research Service scientists in Ithaca, New York, have developed a new tool for studying root architecture, one that brings them out in three-dimensional color. It’s a major step forward in a challenging field.

Studying root-system architecture can be extremely difficult because the opaque nature of soils makes it hard to capture and visualize the root structures. Also, field …

Travel Patterns Of Wind-Blown Soil Microbes, Veronica Acosta-Martinez, Dennis O’Brien

Agricultural Research Magazine

When strong winds carry away soil, microbes in the soil can act like hitchhikers and go along for the ride. With help from a wind tunnel and the latest DNA technology, Agricultural Research Service scientists are shedding light on the travel patterns of these soil-borne hitchhikers. The work has implications for soil health and could lead to management practices that minimize the damage to soils caused by wind erosion.

Scientists have been studying wind-eroded soils since the 1930s, but few studies have focused on wind’s effect on soil microbes. Microbes drive a number of critical processes, such as releasing enzymes …

Emerging Enemy Of Veggies Unmasked, Carolee T. Bull, Marcia Wood

Agricultural Research Magazine

Chic, trendy veggies like arugula and baby broccoli, and familiar stand-bys like Brussels sprouts and cauliflower, are vulnerable to attack by a once-puzzling pathogen. Agricultural Research Service plant pathologist Carolee T. Bull and colleagues have, in laboratory, greenhouse, and field research, detected, identified, renamed, and classified the plant-killing microbe that’s now officially known as Pseudomonas cannabina pv. alisalensis. “Pv.” stands for “pathovar” and indicates that the microbe is a specific pathogenic form, or strain, of a species.

Their work has sorted out some of the taxonomic confusion surrounding classification of the large, complex group of harmful bacteria in …

New Club Wheat Holding Its Own Against Fungal Disease, Kim Garland-Campbell, Jan Suszkiw

Agricultural Research Magazine

Pacific Northwest wheat growers now have added insurance against outbreaks of yield-robbing fungi, thanks to Cara, a soft, white, winter club wheat cultivar developed by the Agricultural Research Service that boasts high levels of disease resistance and outstanding flour quality.

Washington State accounts for 77 percent, or 230,000 acres, of the entire U.S. club wheat crop, with the remainder produced in Oregon and Idaho. Much of the acreage in Washington and Oregon is planted with three cultivars: Bruehl, Cara, and Chukar. Spring-sown club wheat cultivars JD and Eden are grown on another 11,000 acres. Although several other winter club wheats …

A Well Designed Goat Grazing Plan Can Reduce Noxious Weeds, Sterling Banks

All Current Publications

Goat grazing can be an effective tool in reducing noxious weeds, if the right grazing plan is designed and implemented. Areas where herbicides are not an option or limited, goat grazing can reduce noxious weeds by reducing seed production and plant growth.

Annual Costs To Establish And Maintain Birdsfoot Trefoil Pastures In Northern Utah, 2012, Kynda Curtis, Trevor Knudsen, Jennifer Macadam

All Current Publications

This publication is meant to reflect birdsfoot trefoil establishment and maintenance costs on a small-scale cattle grazing area (5 to 10 acres). Birdsfoot trefoil is a perennial legume, and under proper irrigation and management, stands in northern Utah can persist for up to 8 years after seeding. Establishment costs are amortized annually based on a 6 year stand life.

Virtual Water, Marianna Khachaturyan, E. Wesley F. Peterson

Cornhusker Economics

Life on earth depends on water. Unfortunately, water resources are not evenly distributed. There are countries with abundant water supplies, such as Brazil or Canada, and countries that lack water resources, such as Egypt or Jordan. Because water is critical for the production of food and other goods, as well as for human consumption, recreation and ecosystem support, competition among the various users for available supplies is often intense. The problem is compounded by the fact that water markets often work imperfectly or are lacking altogether.

What can countries with limited water resources do? In rare cases, it may be …

The Role Of Speculators In Recent Price Volatility In Wheat Futures Markets, Jacob Delane Holloway

Student Theses and Dissertations

Investors in the agricultural futures markets have been blamed for the recent price spikes. Consequently, policies have been proposed to curb speculation in these markets. This study evaluates "excessive" speculation or the lack thereof in the US wheat markets using hedging ratios, speculative ratios, Working's speculative `T' index and Granger causality tests to examine the investment activities of commodity index traders. The study results show that there is no "excess" speculation in the US wheat markets over the 2006-2011 periods. Indeed, the speculation levels found in this study are not significantly different from historical results reported in other studies and …
