It’s a digital world – and agriculture is no exception. More and more, farmers and ranchers are moving away from traditional methods of getting their news and information. Mobile devices are convenient, budget-friendly ways for farmers and ranchers to stay up-to-date on a variety of agricultural issues.

For a lot of people, the food we eat gives us energy to get through the day. However, it’s important to realize that food is more than just calories; there are compounds in food that are essential to strengthening our bodies and improving our health. Food is functional. These compounds may not be essential for normal functioning in humans, but they do have a beneficial effect on disease prevention and general health.

Scientists at Ohio State University (OSU) have conducted research on two foods that could aid in the fight against prostate cancer: tomatoes and soy. With support from USDA’s National Institute of Food and Agriculture, the Center for Advanced Functional Foods Research and Entrepreneurship at OSU has developed a cancer-fighting tomato soy juice.

Although Mark Hosier was told he’d never walk again, the Indiana farmer is running a 500-acre farm and 10-sow showpig business entirely on his own.  Injured in 2006 when a 2,000-pound hay bale rolled off his tractor on top of him and crushed two vertebrae, Hosier thought he wouldn’t be able to continue farming.  Today, he operates his tractor with the help of a mechanical lift; modifications to his facilities allow him to care for his hogs from a wheelchair.

When members of the Eastern Band of Cherokee Indians can’t make it to their local extension office, their extension office comes to them—with a gift of better health through home gardening.

“Can a School Garden Supplement a Community’s Food Supply in a Sustainable Way?” That was the question asked by Bob Gardner’s fifth grade class at Dayton, Nevada, Elementary School on Tuesday as students presented their science projects to classmates and adult guests.

USDA honors the achievements of American Indians during Native American Heritage Month and year-round.  With educational funding and support from the National Institute of Food and Agriculture (NIFA), Navajo Technical College in Crownpoint, N.M., is one of the many tribal colleges and 1994 land-grant institutions doing considerable work in the scientific fields.

Farmers across the nation are searching for ways to increase farm income.  In Alabama, small and limited-resource dairy goat farmers are boosting the bottom line by adopting “value-added” production techniques to their products.

With the help of researchers and Extension educators from Alabama A&M University and the Alabama Cooperative Extension System, USDA’s National Institute of Food and Agriculture (NIFA) provides funding to support this work through an Agriculture and Food Research Initiative grant for Agricultural Economics and Rural Communities.  And this program is now seeking applications for FY 2013 funding.

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.

Farmers are the ultimate survivors.  By definition, their work requires incredible planning, but it also requires creativity. This year, farmers have faced the test of limited summer rains, which have lowered the productivity of many farmers’ yields.  With fall approaching, farmers have an opportunity to invest today for better outcomes next year by planting what are called “cover crops.” Not harvested like a main crop, cover crops are mowed to stay on top of the soil or disked in for soil improvements.

Cover crops offer a wide range of benefits: they “trap” nitrogen left behind by fertilizer in the field, which otherwise may be washed away over the winter. They conserve water, improve the quality of soil, suppress weeds, and control insect pests and erosion.  Cover crops can also provide an excellent source of animal feed during periods when drought has reduced forage.

USDA science counts conservation research as an important area, so our scientists continually study cover crops, including timely focus on the impacts of drought stress to reduce potential losses in U.S. production capacity.  Using a grant provided by USDA’s National Institute of Food and Agriculture, researchers at Purdue University show that cover crops left on the soil surface after germination in spring will conserve soil moisture acting as a soil cover. This can increase crop yields in dry years and reduce year-to-year variability in yields.

For many military veterans and their families, the transition from the military to civilian life is a complex undertaking; however, reports and personal accounts indicate that many military veterans have discovered that farming offers a place for employment, training and healing.  The problem is there are few educational programs tailored to meet the particular needs and abilities of returning veterans.

The National Institute of Food and Agriculture’s (NIFA) Beginning Farmer and Rancher Development Program (BFRDP) makes it possible to fill that gap in training.  At the University of Arkansas, Dr. Dan Donoghue used BFRDP funds to develop internships, workshops and online courses that focus on the needs of veterans interested in pursuing farming after their service to our country.
