USDA Scientist Eager to Lead New Initiative to Combat a Devastating Citrus Disease

When I learned I was chosen to lead USDA’s new emergency, multi-agency response framework to combat one of the most serious citrus diseases in the world, I felt both humbled and honored.  I relish the opportunity as a scientist to partner with other federal agencies, states, and industry to combat a disease—huanglongbing (HLB or citrus greening)—that has devastated so many citrus groves in Florida and threatens other citrus-producing states.

When Secretary Vilsack established this new framework—USDA’s HLB Multi-Agency Coordination (MAC) Group—he directed us to fund the most promising, practical research to give growers tools to use against HLB as quickly as possible.  USDA provided $1 million in funding, and the 2014 Federal budget includes an additional $20 million for HLB research, which the Group will collectively determine how best to spend.

Consortium Uses Innovative Research to Tap Key Groundwater Source for Rural Region

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

As a major underground water source, the Ogallala Aquifer plays a key role in the economic vitality of vast stretches of the rural Midwest.  The aquifer covers around 225,000 square miles in 8 states from South Dakota to Texas, supplying 30 percent of all U.S. groundwater used for irrigation.

But as with other natural resources that seem inexhaustible, the aquifer is effectively a nonrenewable resource. Demand from agricultural, municipal and industrial development on the Great Plains has meant that water is pumped out of a large portion of the aquifer much more quickly than it can ever be replenished.

Northern Plains Climate Hub Aims to Help Producers "No Matter What the Weather May Bring"

Weather dominates the conversation at local coffee shops and community gathering locations across the Northern Plains.  Depending on the time of the year, I’ve heard things like this:

“We sure could use rain - really dry out there. Cattle are going to have to come off the pastures soon.”

Or…

“Hoping the rain will break here for a few days so I can get the hay cut without it getting rained on this time.”

Midwest Climate Hub to Help Producers, Coordinate Climate-Related Agricultural Research

Flooding and water damage in the Park and Tongue River Watershed

Producers endure the weather across the Midwest and wonder if it will be too wet to plant, too wet to harvest, too wet to spray, or if the rain will come at the right time to produce a bumper or just an average crop. In all of the presentations I have given on climate and agriculture across the Midwest, during the last year the prevailing question has been about whether the increasing variation in precipitation and temperature we’re experiencing is the “new” normal during the growing season. Producers point to the last four growing seasons as examples of the variation they face each year: 2010 was hot and wet during the grain-filling stage of growth causing the crops to mature more quickly, 2011 was almost normal with some dry periods during the last part of the growing season, 2012 was a drought year, and 2013 experienced two different extremes. In 2013, it was wet in the early growing season, delaying and in some places preventing planting, followed by a dry summer.  Across the Midwest, the early spring rains are increasing erosion from fields. Producers are now asking what they can do to protect their natural resources and the crops that depend on them, and what the next season will be like. If these extremes continue, how do they adapt their farming operations?

Student Agricultural and Food Systems Innovation Prize Launched - Help Innovate Agriculture!

Food ties all of humanity together, and making sure there is enough to go around while conserving our natural resources is critical to USDA’s mission. Our researchers think about how to sustainably produce greater quantities of safe and nutritious food every single day. Our in-house science agency, the Agricultural Research Service, has labs across the country that work on just those problems, while our National Institute of Food and Agriculture seeks out the most promising ideas from our university partners and awards the funding needed to get started.

Sometimes, all it takes is a fresh perspective to make a big jump in progress.

From Granddad's Garden to Global Food Security

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

As a boy, Steven Cannon helped his grandfather in the garden grafting fruit trees, all the while developing an interest in plants. As an adult, Cannon has followed in his grandfather’s footsteps, working with USDA as a scientist—but only after first taking a different, though ultimately, complementary career path.

After graduating college, Cannon worked various jobs, including one as an educational software designer that used his knack for computing.  In 2000, he rekindled his early interest in plant biology, earning a PhD and practical experience as a postdoctoral researcher assigned to a genome mapping project. In 2006, he accepted a position as a plant geneticist with the USDA-Agricultural Research Service (ARS) Corn Insects and Crop Genetics Research Unit in Ames, Iowa.

USDA Researchers Study Hydromulches with Guar Gum Substitutes

In the depths of winter, planting grass seed isn’t at the top of one’s to-do list. But soon, spring will arrive and landscaping companies will be out, spraying that green mixture of seed and mulch on patches of bare ground.

Hydromulch, a temporary, porous layer that can help protect newly sown seeds, contains water, dye, a mulching material, and a binder, which keeps the mulch intact. Typically the binder is made from guar gum, made by grinding beans of the guar plant into powder. When water is added, the powder forms a viscous gum.

Kitty Litter: Potential New Use for Spent Corn Grains

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA's rich science and research portfolio.

Sometimes, the results of USDA science show up in the most unlikely places—maybe even in your cat’s litter box.

USDA Agricultural Research Service (ARS) scientists have discovered a way to make kitty litter that's nearly 100 percent biodegradable by processing spent grains left over from corn ethanol production.

And what’s good for you and your cat may also be good for the environment. ARS researcher Steven F. Vaughn and his colleagues have shown that litter made with these grains as the starting material may prove to be more environmentally friendly than popular but nonbiodegradable, clay-based litters that mostly end up in landfills.

Secretary's Column: Supporting Innovation for Stronger Rural Communities

American innovation is one of our most special traditions, fueling our nation to new heights over the course of our history. Innovation is critically important in rural America, where research is helping to grow American agriculture, create new homegrown products, generate advanced renewable energy and more.

Continued research has the capacity to lead the way to economic opportunity and new job creation in rural areas – and USDA has been hard at work to carry out these efforts.  But we need Congress to get its work done and provide a new Farm Bill that recommits our nation to innovation in the years to come.

NIFA Signs Pact to Promote and Support U.S.-Israeli Agricultural R&D

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA's rich science and research portfolio.

On November 22, the United States and Israel came one step closer to renewing agricultural research and development activities that could produce new knowledge and innovations beneficial to both countries and increase the economic bottom line for farmers and ranchers.

Dr. Sonny Ramaswamy, director of the U.S. Department of Agriculture’s National Institute of Food and Agriculture (NIFA) and Edo Chalutz, executive director of the U.S.–Israel Binational Agricultural Research and Development Fund (BARD), signed a memorandum of understanding (MOU) to promote collaboration via NIFA among U.S. and Israeli scientists and engineers. BARD and the Agricultural Research Service (ARS), USDA’s intramural research agency, have cooperated on research together since BARD’s inception.
