A multi-institutional study led by scientists in the Agroecosystem Sustainability Center (ASC) at the University of Illinois Urbana-Champaign concluded that although soil moisture varies significantly both within a single field and from field to field due to varying soil properties and different management practices, soil moisture distribution relative to the field average remains consistent across time within each field. 

As greenhouse gases go, nitrous oxide (N2O) is a doozy. With a global warming potential 273 times that of carbon dioxide, mitigating N2O could make a big difference. But before mitigation can happen, it’s important to understand where the compound is coming from. 

Illinois landowners could be eligible for $5,000 in free soil analyses and consultation with a University of Illinois Urbana-Champaign research team in exchange for participating in a historic project seeking to learn how soils have changed over 120 years. 

Soils are not just key to crop production and food security. They form the literal foundation supporting homes, roads, septic systems, and other essential infrastructure. That’s why students in NRES 285, a laboratory and field soil judging course, learn to identify important physical properties of soil. And they’re good at it.

URBANA, Ill. — Like every industry, modern farming relies heavily on plastics. Think plastic mulch lining vegetable beds, PVC pipes draining water from fields, polyethylene covering high tunnels, and plastic seed, fertilizer, and herbicide packaging, to name a few.

Earth’s soil contains large stocks of carbon — even more carbon than in the atmosphere. A significant portion of this soil carbon is in organic form (carbon bound to carbon), called soil organic carbon (SOC). However, SOC has historically been greatly diminished by agricultural activity, releasing that carbon into the atmosphere as carbon dioxide, contributing to climate change.

URBANA, Ill. — Let’s say you’re a corn grower farming on low-fertility soil. How do you go about making that soil healthier and more fertile? Many farmers think if they add plenty of nitrogen fertilizer, that nutrient, along with carbon, will be stored in the soil as organic matter when microbes decompose crop residue.

URBANA, Ill. – In 1876, when University of Illinois professor Manly Miles established the Morrow Plots, he couldn’t have imagined the plots would become the oldest continuous agricultural experiment in the Western Hemisphere. Nor could he imagine, more than a century before the dawn of the internet, that the plots’ data would be digitized and made available online to scientists, students, and educators around the world.

URBANA, Ill. – When he heard an old barn on the University of Illinois campus was scheduled for demolition, soil scientist Andrew Margenot went to investigate. Inside, on dusty shelves, he discovered a time capsule in the form of thousands of jars of soil from around the state, some dating as far back as 1862. 

URBANA, Ill. – Sometimes, a summer can change everything. For several undergraduate women in the College of Agricultural, Consumer and Environmental Sciences (ACES) at the University of Illinois, a summer internship with the USDA’s Natural Resources Conservation Service revealed new career goals and delivered the skills and experience to get there.
