When you sit down to your Thanksgiving feast and reflect on the bounty on your table, you might want to say a quiet “thank you” to the agricultural researchers who have made your holiday favorites so plentiful and so good for you, too.

Let’s start with the Thanksgiving star: the turkey.  This Native American bird was rapidly slipping in popularity in the 1930s because smaller family size and smaller iceboxes meant there were too many unwieldy leftovers from the big birds.

Some Arizona growers rely on broad-spectrum insecticides to treat whiteflies, but scientists with the USDA’s Agricultural Research Service (ARS) are studying the option of letting nature lend a hand in combating the costly pests.

It’s hard to believe that ancient seas once covered a large part of California’s San Joaquin Valley—until you check the soils.

Organic agriculture is proving itself to be a veritable cornucopia, according to the results of the first-ever report on certified USDA organic production, which we released earlier this month. While the number of organic farms is a fraction of its conventional counterpart, an organically produced version of virtually every crop or animal product is now available in the United States.

This was the first time the National Agricultural Statistics Service (NASS) conducted this survey, which means that we cannot see trends yet, but we can already easily see some of the impacts of organic production in the United States. From four farms in Alabama, Alaska or Delaware to 1,898 farms in California, every state in the nation is now home to USDA-certified organic producers. And while these farmers make up less than a half of one percent of all U.S. farmers, they already sell more than $3.5 billion worth of agricultural products.

It’s shaping up to be a good year for students in Indian Country.

For the first time in school history, students at Saginaw Chippewa Tribal College in Mount Pleasant, Michigan can register to take physics thanks to an upgraded laboratory. And at Leech Lake Tribal College in Cass Lake, Minnesota, students were able to take trigonometry for the first time last year.  Funded and supported by USDA’s National Institute of Food and Agriculture (NIFA ), both schools made  improvements to bolster their students’ learning in the areas of science and mathematics.

NIFA’s Tribal Colleges Education Equity Grant is a noncompetitive program that enhances educational opportunities for American Indians in the food and agricultural sciences.  These grants strengthen formal educational opportunities at the associate, baccalaureate, or graduate level at 1994 land-grant institutions, also known as tribal colleges.

Even back in the days of Mark Twain’s riveting tales of steamboat pilots and derring-do on the Mississippi River, it was known that you could catch a crook by means of almost invisible clues left at the scene of the crime:  the unique patterns of his fingertips.  How do we know this? In Twain’s “Life on the Mississippi,” published in 1883, a murderer was identified by his fingerprints.

From ensuring the sustainability of our water resources, to breeding crops tolerant to changing climactic conditions, to preparing for the increased food demands of 9 billion people by 2050, finding solutions to the biggest agricultural challenges we face will require a new level of scientific innovation, coordination and long-term planning.  As Iowa State University’s College of Agriculture and Life Sciences Associate Dean Joe Colletti recently put it, ag science is not rocket science - it’s more complicated than rocket science!

True or false?

• Since 1985, the amount of rice available for Americans to eat has nearly doubled, from 11.6 to 21.2 pounds per person in 2010.
• In 2010, pineapples were America’s favorite canned fruit, and tomatoes were our favorite canned vegetable.
• U.S. milk availability, which peaked at 44.7 gallons per person in 1945, was 20.1 gallons per person in 2010.

Answers (all true) can be found in the Economic Research Service’s Food Availability (Per Capita) Data System—a unique data set revealing the types and amounts of food commodities available for U.S. consumers to eat.

One of the most frequent questions I receive at the National Agricultural Statistics Service (NASS) is, “How can we accurately forecast agricultural production?” After all, anyone in the agriculture industry knows that regardless of how accurate you are, every year the weather can wreak havoc on any forecasts. This is why NASS doesn’t simply rely on formulas when we prepare our forecasts. Our data incorporate input from hundreds of thousands of farmers and ranchers across the United States.

The past few years have given us a great opportunity to highlight the importance of farmer surveys. Last year, producers were battered by some of the most significant floods on record, which were followed by a summer that broke several heat records. Although many crops were affected, one result was that U.S. growers produced significantly less wheat. North Dakota farmers, the nation’s leading Durum wheat growers, planted a record-low number of acres in 2011. If farmers themselves didn’t report this information to us, there would be no other way NASS could accurately estimate the results of such an unusual year.

Over the past decade, we’ve seen a lot of variability in the weather, with severe droughts in some places, excessive flooding in others, and more extreme weather events all over the country.  While there has always been variability in the weather, scientists predict increasing variability in weather patterns as the concentration of greenhouse gases (GHG) increases in the atmosphere. Such changes present challenges for farmers, who, in many areas, are trying to grow crops under hotter, drier climate regimes and must protect their crops from damage during extreme weather events.  That’s why the USDA is actively doing research on how to produce crops and livestock through increasing climate variability, and that’s why the fourth in a series of Office of the Chief Scientist white papers on the Department’s research portfolio is focused on what USDA science is doing to help prepare the agency, and the nation’s farmers for a changing climate.
