One of the most exciting aspects of my job as the head of USDA’s National Agricultural Statistics Service (NASS) and an advocate for statistical literacy is to see students coming into the profession of statistics. We are fortunate, according to Bob Rodriguez, past-president of the American Statistical Association (ASA) in a column published in ASA’s AMSTATNEWS, “that the number of students majoring or minoring in statistics is soaring because of positive experiences in AP Statistics courses. The word is out that statistics is a ‘must’.”

Engaging students even earlier than high school is important not only for developing future statisticians but also so that they understand the importance of responding to surveys.  Both private and government statistics, including those about agriculture from my agency, are dependent on voluntary survey response.

The average consumer might not think about it, but for decades, USDA plant breeding research has been producing varieties that have been helping feed the world and preserve the environment. We know that you look for the plumpest, juiciest strawberries at your neighborhood market, so USDA plant breeding scientists worked to find the genes to make them taste even better.  And to help farmers in Northern climates produce more food for our tables, USDA plant breeding researchers developed corn that would mature early before the bitter cold arrived. This important work plays a significant role in our lives and USDA hopes to build on all these positive outcomes to make sure even more keep coming.  Therefore, to coordinate work on plant breeding and maximize the results from ever more limited resources, USDA formed a new Plant Breeding Working Group (PBWG) earlier this year.

Unlike the math and agricultural statisticians with whom I work daily, I took a completely different career path into the world of agricultural statistics. In college, I started out as an accounting major at Shepherd University, Shepherdstown, WV. Based on the recommendation of friends, I took some courses in computer programming and the love affair began when I was introduced to Fortran and Cobol. After college, I stuck to my IT knowledge and went into sales revolving around IT solutions for government contractors and customers including Dulles Airport, Martin Marietta, and Contel. These experiences taught me to think logically, to put myself in the other person’s shoes, and to communicate effectively.

When you plunk down $17.99 for a bottle of your favorite premium olive oil, you’d like some assurance that what you just bought actually is top-quality olive oil.  Sadly, there’s a possibility that your high-priced olive oil might be watered down with other, less expensive vegetable oils, such as those from safflower or canola.

Fortunately, the scientists of the Agricultural Research Service (ARS) are helping ensure that what you get is what you paid for.

Did you know that more than 11 million Americans worked on farms in 1930, of which 8.3 million were family workers? Compare that to the fewer than 1.5 million workers employed in agriculture during the peak harvest months of 2011.

Every year, the Department of Agriculture releases a reference book of major agricultural statistics for the United States and countries around the world. It is a one-stop location for annual production, consumption, trade, and price data for all sorts of crops and livestock, as well as spending for government programs, farm economics, and lots of other statistics important to our country’s agricultural system. Agricultural Statistics has a long history of publication, and is an important archive for researchers to study the history of U.S. farming.

Most people don’t equate aviation with agriculture, but two USDA partners, Washington State University (WSU) and members of a Texas 4-H Club, received the chance to participate in the 2013 Paris Air Show, which was held June 17-23.

In 2010, USDA’s National Institute of Food and Agriculture awarded WSU with a $40 million grant to develop effective alternative biofuels for commercial and military jets. The project, the Northwest Advanced Renewables Alliance (NARA), is working to convert closed timber mills into bioenergy development centers, which will improve the economic potential of rural communities affected by the downturn in timber production. The team is focusing on feedstock development, sustainable forest production and establishing new methods to identify the most promising plant lines for biofuel conversion. NARA aims to develop a regional source of renewable aviation fuel for Seattle-Tacoma International Airport.

In the wake of the economic downturn that began in late 2007, food insecurity in households with children remains near the highest level observed since monitoring began in 1995. In 2011, 20.6 percent of U.S. households with children were food insecure—unable at some time during the year to acquire adequate food for one or more members due to insufficient money or other resources for food.  In about half of those households, only adults experienced reduced food quality or quantity, but in 10 percent of all households with children, one or more of the children were also affected.

Food security is especially important for children because the foods they eat—or don’t eat—affect not only their current health and well-being, but also their development and future health. Studies suggest that children in food-insecure households are more likely to have negative health and development outcomes than children in otherwise similar food-secure households, such as poorer health, more frequent colds, and lower math and reading achievement.

Chances are that you—or whoever’s the “grillmaster” at your house—have your own “secret ingredient” for making grilled burgers taste even better.  But it might surprise you to know that  Agricultural Research Service (ARS) scientists and their university colleagues also are working on secret ingredient for a better burger, although their interest focuses on food safety rather than flavor.

They’ve been testing the capacity of olive powder, a byproduct of olive processing, as a weapon against Escherichia coli O157:H7, and the powder’s potential to retard the formation of undesirable substances called heterocyclic amines while the patties are being grilled.

Some say careers in agriculture are a thing of the past, but don’t tell that to Krish Jayachandran, a professor and co-director of Florida International University’s (FIU) Agroecology Program. He will tell you that agriculture is the wave of the future—and he is backing that statement with nearly a decade of work to ensure the next generation of agricultural scientists are ready.

“If we are going to feed more than 9 billion people in the future, we have to get creative in how we use our soil and water resources—not to mention our over-reliance on the same kind of germplasm decade after decade,” Jayachandran said. “I tell students that agriculture research is not farming, it is science and technology. It’s thinking about bio-geo-chemical processes and nutrient cycling; on-farm and off-farm remediation measures, surface and groundwater management, and bioenergy.”

If you’re of a certain age, you might remember General Douglas MacArthur’s famous corncob pipe, or the one sported by “Granny” on the hit TV show “The Beverly Hillbillies.” But aside from those picturesque examples, corncobs have tended to mostly be considered a waste product left over from the harvest of the golden, juicy kernels of corn.

That’s in the process of changing, thanks to the scientists of the Agricultural Research Service (ARS).  For starters, they’ve shown that corn cobs left in the field after harvest can boost soil quality.  Beyond that, those tough cobs can be used to make a whole host of products.
