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.

A recent sighting of a threatened snake in Georgia by partners of USDA’s Natural Resources Conservation Service (NRCS) shows how conservation work helps wildlife.

The Orianne Society and the Georgia Department of Natural Resources, two key NRCS partners, spotted an Eastern indigo snake in an area where NRCS and landowners have worked together to restore wetlands, an ecosystem where the species typically spends several months of the year.

The Eastern indigo snake is a large nonvenomous snake found in Georgia and Florida. Its historic range also included Mississippi, Alabama and South Carolina, and it’s the nation’s longest native snake. The snake was listed as threatened in 1978 because of a lack of habitat and people capturing for pets or killing them.

On a recent trip to California, I had the pleasure meeting several farm families who are impacted by the state's worsening drought. Both stops gave me a first-hand view of the challenges these farmers face. We discussed how USDA can further help them with available resources. While the discussion centered on concerns over water supply, I was heartened to see that the Natural Resources Conservation Service’s (NRCS) recommended conservation practices have helped them better prepare for the state’s historic water shortage.

During the first stop, I visited with a distinguished dairyman and conservationist in Marin County, Bob Giacomini, and his four daughters, who operate the Point Reyes Farmstead Cheese Company. Driving over the hill towards Bob’s milking complex, I could see the pastures had little, if any, grass. In talking to Bob, he said that typically the grass would be at least two feet tall by now. He has real concerns about having enough forage for his cows. I also spoke with Paul Bianchi, who had joined us.  Paul owns a dairy operation in neighboring Sonoma County and, like Bob, is very concerned about his ability to feed his cows. Both discussed the real possibility that they may have to sell some of their herd.

Today, Secretary Vilsack joined the President in Michigan to sign the 2014 Farm Bill, an accomplishment that would not have been possible without your engagement. Last year we began the #MyFarmBill campaign in an effort to share with all Americans the need for a comprehensive Food, Farm and Jobs Bill to keep up momentum in American agriculture. Today that bill was signed and we are able to move forward to do work that grows the rural economy and creates jobs.

The new Farm Bill will allow the proud men and women who feed millions around the world to invest confidently in the future. While no legislation is perfect, this bill is a strong investment in American agriculture and supports the continued global leadership of our farmers and ranchers.  Take a look at how your voices were included in the 2014 Farm Bill:

Grasses for grazing livestock are making a comeback on Utah’s McCracken Mesa thanks to a project partnership among the Aneth Chapter of the Navajo Nation, USDA’s Natural Resources Conservation Service (NRCS) and the Bureau of Indian Affairs.

Known as the McCracken Mesa Rangeland Project, the Aneth Chapter is working to rehabilitate degraded land through a grass establishment project. McCracken Mesa rises 5,500 feet and covers 57,000 acres. An estimated 37,000 acres are intended for grazing livestock. But the mesa’s terrain, extreme weather and overgrazing from livestock have left much of the land bare.

The use of native grasses ensures a more sustainable ground cover for the mesa along with habitat for wildlife. Plants that are native to an area typically are the most suitable for restoration efforts because they boast advantages such as adaptability to the soil and have mastered surviving and thriving in the sometimes harsh environment.

Data on soils on the nation’s 3,265 soil survey areas are now updated and available free online from USDA’s Natural Resources Conservation Service (NRCS).

“This update is a major step-forward in meeting the growing demand for NRCS soils data,” said Dave Hoover, NRCS national leader of Soil Business Systems. “Our soil scientists in every state helped us upgrade all our software and databases, improve our spatial data, and put together a complete suite of soil interpretations and other products our customers want.”

With declining budgets in the public school system, there has been a steady decrease in school fieldtrips in recent years. This plight further widens the disconnect between children and nature.

To help bridge the gap between the schoolroom and the natural world, the Shawnee National Forest will offer a new school program this year called Naturalist in the Classroom.  The program will be piloted to third- through fifth-grade students in Union and Alexander counties located in southern Illinois, and will focus on two themes – forest ecology and wetland ecology.

For years, researcher and filmmaker Buz Kloot suspected something remarkable was happening under our feet.

His suspicion was based on interviews he conducted with farmers from various parts of the country – all of whom reported significant production and environmental benefits by simply improving the health of their soil.

“These farmers reported more consistent yields, lower input costs and higher net income,” said Kloot, a University of South Carolina research associate professor. “They weren’t sneaking out at night to fertilize and irrigate. I had to believe what I saw. And with each visit, these ‘anomalies’ amassed.”

The National Organization of Professional Black Natural Resources Conservation Service Employees recently honored three farm families at their annual outreach and agricultural education exposition.

The Lloyd Wright Small Farmer Award is named after the organization’s founder. The award is given to producers who share a passion for improving awareness and development in the field of agriculture. The organization selected Kentucky rancher William E. Boulden, Jr. for first place, Texas grape growers Alphonse and Martha Dotson for second, and Mississippi ranchers Percy and Emma Brown for third.

Known to her neighbors in Clarke County, Miss. as the blueberry lady, Barbara Robinson has a vibrant 20-acre farm packed with blueberries, muscadines and other produce. Robinson is one of the nation’s many fruit growers, and a recent USDA report shows the land dedicated to growing cultivated fruits, nuts and flowers is rapidly growing.

The National Resources Inventory released recently by USDA’s Natural Resources Conservation Service shows a boom in land dedicated to growing fruits, nuts and flowers, increasing from 124,800 acres in 2007 to 273,800 in 2010. Cultivated refers to farms that plant a second crop amid the fruit, nut and flower crop. This finding is one of many in the newest NRI report.

While the report only provides the numbers and doesn’t make inferences, experts at NRCS say one reason for the growth is more available assistance to fruit, nut and flower growers.
