Consumer demand for organically produced goods has shown double-digit growth during most years since the 1990s, according to industry statistics, providing market incentives for U.S. farmers across a broad range of products. Consumers can now purchase organic food at nearly three out of four conventional grocery stores. These products generally carry a price that reflects the additional costs of producing organic foods and of keeping products segregated throughout the supply chain. The price premiums reflect these costs as well as consumers’ willingness to pay more for organic products.

A new Economic Research Service report provides estimated retail price premiums—and changes in premiums—for 17 commonly purchased organic foods relative to their nonorganic counterparts from 2004 to 2010. We used grocery store purchase data from a large set of nationally representative households. The data included detailed information on each product (degree of processing, flavor, package size, and whether organic), its price, and where it was purchased, allowing us to isolate the organic price premium.

The goal of USDA’s Hispanic-Serving Institutions National Program (HSINP) Future Scientists Program is to enhance the scientific knowledge of teachers, helping them to become more effective in encouraging student interest and progress in science. Teachers in the program attend two-day summer institutes at Agricultural Research Service (ARS) labs nationwide, where scientists introduce them to various research projects. ARS researchers share scientific knowledge with the teachers, who then share it with their students to encourage them to become future scientists.

One of the catalysts for this lofty goal is a tiny, inconspicuous and innocuous caterpillar—the corn earworm that wreaks havoc in corn fields nationwide as an agricultural pest.  This program began in 2003.  I brought 10 teachers into the ARS Southern Plains Agricultural Research Center (SPARC) in College Station, Texas, for a summer institute that included teachers studying in corn research plots searching for corn earworm caterpillars in 100-degree heat! It was the first time I made caterpillars the focus of this program.

It’s a case of “darned if you do, darned if don’t.”

Responding to Climate Variability is one of the goal areas of the REE Action Plan.  The objective is to develop science-based knowledge to address climate variability, position agricultural communities to reduce emissions of greenhouse gases, and enhance carbon sequestration.

Many valuable USDA accomplishments for the year 2015 were the result of cross-divisional teams that developed useful tools to support decision-makers with research-based data.  Knowing weather and climate patterns--driving forces behind the success or failure of cropping systems--is vital information to land managers.  One such tool, AgroClimate, supported by REE and the National Oceanic and Atmospheric Administration (NOAA), helps users manage climate risk with tools that provide information on crops best suited to grow in their region, based on water availability and the amount of water a crop will use.

Today we learn more about how the National Institute of Food and Agriculture invests in and advances agricultural research, education and extension and seeks to make transformative discoveries that solve societal challenges.

Seventy years ago, when Nat “King” Cole first regaled us about roasted chestnuts in The Christmas Song, not many Americans could actually enjoy the treat because American chestnut trees were in dire straits.

The predominant tree in Eastern American forests was nearing the tail end of a 50-year blight that killed an astonishing three to five billion trees, making the species functionally extinct. Now, however, researchers supported by USDA’s National Institute of Food and Agriculture (NIFA) are working to restore the American chestnut and may be only a few years away from bringing back the iconic tree.

An epidemic of wheat blast is underway in Bangladesh, published reports say, and losses may be substantial in the six southeastern districts where it has been reported. Wheat blast is a crop disease caused by the Triticum pathotype of the fungus Magnaporthe oryzae (MoT). In nations where broad wheat blast epidemics have occurred, 30 percent losses have been noted, but localized areas have experienced 50-100 percent losses, according to Dr. Barbara Valent, fungal molecular geneticist at Kansas State University (KSU).

The U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA), through its Agriculture and Food Research Initiative (AFRI), has provided nearly $5.4 million since 2009 to support research on wheat and rice blast. KSU leads a multi-institutional research project that brings together expertise from University of Arkansas, University of Kentucky, the Ohio State University, Purdue University, and USDA’s Agricultural Research Service.

For many veterans, agriculture may be a career choice worth exploring when they return to civilian life. Veterans have discipline, passion and a sense of service—qualities that would translate well for anyone interested in getting into agriculture.

That may be why a collaborative USDA training project is such a hit. The program, run by Agricultural Research Service (ARS) scientists and their partners in Fayetteville, Arkansas, trains veterans in the basics of agricultural practices by offering workshops, online courses, internships and “Armed to Farm” boot camps at various sites, including the University of Arkansas campus in Fayetteville.

Farmers love data. And while big picture items are great, growers tell us they really want and can use local data. In addition to national and state-level statistics, some of our most popular data are the county-level agricultural production information that we collect and publish.

Collecting local data is not an easy task. For example, in Iowa, where I oversee agricultural statistics, to determine 2015 county-level numbers, we surveyed 11,500 farmers in December and January to supplement data from nearly 3,000 Iowa farmers surveyed for the January 12^th Crop Production Annual Summary report. These statistical surveys are designed so all farmers in the state have a chance to be selected for participation. In order to publish county data, we need responses from at least 30 producers in each county or yield reports for at least 25 percent of the harvested acreage in a county. Luckily, here in Iowa, we received 50 or more farmer reports for many counties but we still had a couple of counties that did not make the 30 report requirement for publication.

I serve as Co-Chair of the Interagency Committee on Human Nutrition Research (ICHNR), which on March 4 released the first-ever National Nutrition Research Roadmap. This document will help guide government, academia, and the private sector to more effective collaboration on federally funded human nutrition research. Accordingly, the Roadmap itself is the result of more than a year of collaboration among 10 different federal departments and agencies, more than 90 federal experts, and numerous public comments.

The American people are keenly interested in knowing which dietary choices will help them to be healthy and prevent chronic diseases. Research on this relationship between nutrition, dietary choices, and health is important, because even a small impact on health could have large economic benefits to society. In fact, improved nutrition could be one of the most cost-effective approaches to address many societal, environmental, and economic challenges facing the US and nations around the globe. The Roadmap will help make federally supported nutrition research more effective and productive by identifying knowledge gaps and breakthrough opportunities that can be addressed through coordination and collaboration.

March is National Nutrition Month, an annual observance that encourages Americans to adopt a healthy eating pattern that includes nutritious and flavorful foods. What started as a week-long event in 1973 by the Academy of Nutrition and Dietetics became a month-long celebration in 1980, thanks to growing public interest in nutrition. Food and nutrition professionals often celebrate this special month by providing educational and fun resources and treats—such as information booths, posters, games, recipes, and healthy snacks—to promote healthy eating in the workplace and at home. This year’s theme, “Savor the Flavor of Eating Right,” encourages food traditions and the appreciation of eating flavorful foods with friends and family.
