Corn bred with genes from wild relatives can reshape soil microbial communities and reduce nitrogen loss — with no yield reduction — according to new research from the University of Illinois Urbana-Champaign. The advancement marks the first time corn’s genetic makeup has been linked with inhibition of nitrifying and denitrifying bacteria, the microbes responsible for turning fertilizer nitrogen into forms that pollute water and contribute to climate change.   

The ubiquitous plastic beverage bottle makes up about half of plastic waste collected for recycling in the U.S. Most recycled plastic is processed domestically, but a portion is traded overseas. A new study from the University of Illinois Urbana-Champaign draws on citizen science data to investigate how the global plastic waste trade contributes to litter along coastlines and waterways in importing countries.

Thanks to research breakthroughs by CABBI’s internationally known miscanthus experts and geneticists, this unique plant is poised to be a game-changer on the bioenergy front — and beyond.

Airplane travel is more popular than ever, and our desire for fast transportation means jet fuel has become a major contributor to greenhouse gas emissions. Now, researchers at the University of Illinois Urbana-Champaign have discovered a novel way to address that problem—by converting food waste into sustainable aviation fuel (SAF) that meets industry standards without relying on fossil fuel blends.

Wetlands are an important part of the ecological system, providing a myriad of benefits for people, wildlife, and the environment. They also serve as “nature’s kidneys,” filtering out pollutants from surface water. A new study from the University of Illinois Urbana-Champaign finds that wetlands along the Mississippi River Basin effectively clean up nitrogen runoff from agricultural fields.

Students in the College of Agricultural, Consumer and Environmental Sciences know communication is key. From public speaking requirements to advanced composition classes, ACES students are trained to share their knowledge with the world. Pam Leiter, the recruitment coordinator for the Department of Natural Resources and Environmental Sciences, is part of that effort.

Illinois once harbored more than 8 million acres of wetlands. By the 1980s, all but 1.2 million wetland acres had been lost, filled in for development or drained to make way for agriculture. Now, thanks to a 2023 Supreme Court decision, roughly 72% of the remaining 981,000 acres of Illinois wetlands are no longer protected by the federal Clean Water Act, putting communities at risk of losing the flood control, groundwater recharge, water purification and natural habitat these wetlands provide, researchers report.

In a decisive new study, crop scientists at the University of Illinois Urbana-Champaign and USDA’s Agricultural Research Service show that soybeans are doubly damaged by drought and ozone pollution, both of which are increasing across the globe due to climate change.  

A team of agricultural economists, environmental scientists and policy experts envisions a path toward a carbon-neutral agricultural future by expanding the reach of policies designed to promote low-carbon biofuels for transportation and aviation. In a new paper in the journal Science, the researchers propose policies that would reward farmers for adopting “climate-smart” practices when growing biofuel crops and remove the hurdles that currently thwart such efforts.

Tile drainage is a common practice used in agricultural fields to remove excess water, but it also transports harmful nutrients into water bodies, contributing to algal blooms that deprive aquatic life of oxygen. Woodchip bioreactors are an efficient way to reduce nitrogen pollution by treating the water as it exits the field. However, these denitrifying bioreactors may leach phosphorus from the woodchips into the environment.
