The legacy of corn nitrogen fertilizer: Study shows lengthy impact in tile drained systems

Midwestern soils are among the most productive in the world, thanks in part to extensive tile drainage systems that remove excess water from crop fields. But water isn’t the only thing flowing through tile drains. Nitrogen moves along with soil water into drainage ditches, streams, and ultimately into the Mississippi River Basin, where the nutrient contributes to massive algal blooms and hypoxic conditions that impact aquatic life in the Gulf of Mexico.

Illinois continues work to improve waterways by reducing nutrient pollution

The loss of nutrients into Illinois’ lakes, streams, and rivers harms water quality here and downstream all the way to the Gulf of Mexico. The Illinois Nutrient Loss Reduction Strategy, NLRS, was established in 2015 and is designed to reduce nutrient pollution in Illinois’ waterways and the Mississippi River and its negative impacts by exploring and recommending practical, research-based nutrient loss practices and collaborating with partners across the state.

Study forecasts tile drainage and crop rotation changes for nitrogen loss

URBANA, Ill. – Midwestern agriculture contributes the vast majority of nitrogen in the Gulf of Mexico, causing an oxygen-starved hypoxic zone and challenging coastal economies. State and federal policies have tried for decades to provide solutions and incentives, but the hypoxic zone keeps coming back. A recent study from the University of Illinois offers a new way to understand Midwestern nitrogen dynamics and forecasts future nitrogen loads under various management scenarios across the region.

The little algae that could: algal growth helps clean up toxic wastewater

URBANA, Ill. – You may not want to see algae spreading a green carpet on your favorite lake. But in toxic wastewater, tiny algal organisms become potent powerhouses that eat nutrients and produce oxygen, helping to convert poisonous sludge to reusable biomass.

A new study from the University of Illinois explores growth and viability of four different algae species in wastewater from biocrude oil production.

Illinois, Nebraska scientists propose improvements to precision crop irrigation

URBANA, Ill. – With threats of water scarcity complicating the need to feed a growing global population, it is more important than ever to get crop irrigation right. Overwatering can deplete local water supplies and lead to polluted runoff, while underwatering can lead to sub-optimal crop performance. Yet few farmers use science-based tools to help them decide when and how much to water their crops.

How the humble woodchip is cleaning up water worldwide

URBANA, Ill. – Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen in drainage water. Whether it flows out to the Great Barrier Reef or the Gulf of Mexico, the nutrient contributes to harmful algal blooms that starve fish and other organisms of oxygen.

Global Classrooms initiative will connect ACES undergraduates with peers abroad for project-based learning

Undergraduates from the College of Agricultural, Consumer and Environmental Sciences (ACES) will soon have the opportunity to work with other students around the world to support children’s health and design water projects. Thanks to the new Global Classrooms initiative and our faculty’s commitment to create such courses, these invaluable “international” experiences will be available from Illinois-based classrooms.

No-till practices in vulnerable areas significantly reduce soil erosion

URBANA, Ill. – Soil erosion is a major challenge in agricultural production. It affects soil quality and carries nutrient sediments that pollute waterways. While soil erosion is a naturally occurring process, agricultural activities such as conventional tilling exacerbate it. Farmers implementing no-till practices can significantly reduce soil erosion rates, a new University of Illinois study shows.
