In a decisive new study, crop scientists at the University of Illinois Urbana-Champaign

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.

University of Illinois Urbana-Champaign alumnus Eric Hodel didn’t begin his career expecting to lead one of the nation’s largest faith-based food banks.

Another round of excessive heat is on the way through much of the United States next week, with heat indices predicted to reach 110 degrees Fahrenheit or more in many locations. 

Every time Fred Below and Connor Sible meet with Illinois farmers, they get the same question. “What’s the story with these biologicals? Do they work?” 

When most growers plant corn, they expect perfect, uniform rows and plump and pearly yellow kernels lining the cob. But a group of USDA Agricultural Research Service scientists intentionally plant the misfits — some gnarled and speckled, others sprouting tassels where ears should be — to perpetuate the wide array of genetic variation in the Midwest’s most economically important crop. 

Drones can now detect subtle soybean canopy damage from dicamba at one ten-thousandth of the herbicide’s label rate — simulating vapor drift — eight days after application.

The global food system faces growing risks from climate change, even as farmers seek to adapt, according to a June 18 study in Nature.

In contrast to previous studies suggesting that warming could increase global food production, the researchers estimate that every additional degree Celsius of global warming on average will drag down the world’s ability to produce food by 120 calories per person per day, or 4.4% of current daily consumption. 

Inside a large walk-in refrigerator on the University of Illinois Urbana-Champaign campus, thousands of envelopes hold the fate of global food security, not to mention a significant portion of the world’s economy.
