World Soil Day – A Time to Celebrate the Foundation of Agriculture

Amy Overstreet, NRCS Public Information Officer, created a video series for the 2015 International Year of Soils to raise awareness and appreciation for everything that soil provides.

Last year during the International Year of Soils (IYS), I had the incredible opportunity to help the USDA-Natural Resources Conservation Service (NRCS) spread the word about the many life-giving functions of soil. As part of this effort, I traveled to New York City to attend the kickoff ceremony for IYS at the United Nations, which was held on World Soil Day.

In 2014, the United Nations General Assembly designated December 5 as World Soil Day. It is observed this day each year to honor the birthday of King Bhumibol Adulyadej of Thailand, the world’s longest reigning monarch, who passed away in October. He played a pivotal role in the promotion of soil science and conservation, and was a leader in sustainable land resource management. Read more »

‘Soil and Air’ – Where Crops Meet the Environment

You probably know that climate change affects how we grow food, but you might not know that how food is grown also affects our climate. This interplay is at the heart of an Agricultural Research Service (ARS) project called “Soil and Air,” a concerted effort to feed the Earth’s 7.5 billion people while protecting the planet.

Farmers and ranchers produce food at the intersection of soil and air, which in turn impacts soil and air quality. For instance, warmer air creates warmer soil, leading to different compositions of bacteria and other microbes in the ecosystem and to increased moisture loss through evaporation. Read more »

Farming Nature’s Way

The left sample, after 11 years of continuous no-till farming. The right sample, conventional tillage

These two soil samples are the same soil type. The one on the left is after 11 years of continuous no-till farming. The one on the right is conventional tillage.

No-till farming used to be only about reducing soil erosion. Today, continuous no-till is the preferred tillage system in some areas. Why? It’s all about soil health.

The loss of organic matter in soil, which is the lightest soil component and the first to wash away, is the healthiest portion of our topsoil. It is the house where the biological systems in our soils live and includes everything from the tiniest organisms like bacteria, algae, fungi, and protozoa to the more complex nematodes, micro-arthropods (think tiny spiders), and the more visible earthworms, insects, small vertebrates, and plants. They are all part of healthy soil. Read more »

Soils in the Classroom: Celebrating the Discovery and Donation of a Historic Soils Collection

Thanks to the efforts of a dedicated science teacher from New Jersey, a valuable piece of soil science history is now available for viewing and research among the special collections at USDA’s National Agricultural Library (NAL) in Beltsville, Maryland.

Jill Guenther, who has taught Earth and space science for 29 years, discovered the antique soils collection tucked away in a classroom cabinet. “I knew it was something special, and I wanted to use it as a display when teaching erosion and conservation issues,” she explained. Read more »

Southeast Regional Climate Hub Celebrates Agriculture Champions of Change

The White House recognized 12 Champions of Change for their leadership in sustainable and climate-smart agriculture.

The White House recently recognized 12 Champions of Change for their leadership in sustainable and climate-smart agriculture. This week we will meet them through their USDA Regional Climate Hub, today featuring the Southeast’s William “Buddy” Allen and Donald Tyler.

Farmers, ranchers, and forest land managers across the Southeast are at the forefront of climate change and its various effects on their operations, yields, and profits. Many of these producers know that adaptive agriculture practices can benefit soil, air, and water quality and at the same time increase resilience to climate change and other environmental threats. Communities and businesses that support climate-smart agriculture in turn are creating jobs and growing the rural economy.

USDA’s Southeast Regional Climate Hub works to bring land managers in the Southeast the science and other tools that can help them adapt to changing weather/climate conditions. Many farmers, ranchers and land managers are already leading efforts to develop and demonstrate the value of sustainable agricultural practices that benefit soil, air, and water quality while helping to mitigate climate change by reducing emissions.  Educators and advisors have also been crucial in bringing science-based, sustainable, and climate-informed agricultural practices to the agricultural community.

Restoring Appalachian Soils to Restore the Forests

The land of forest-covered hills, mountain music and coal has a lesson for restoration: healthy forests require healthy soils.

The forests of Appalachia, a region that extends from southern New York to Georgia, are considered to be among the most diverse temperate deciduous forests in the world, with as many as 30 different tree species growing together.  Coal has played an important role in the development of Appalachian culture, but mining for coal has also created a need for restoration in extensive areas of the 13 states that make up the Appalachian region.
