Agriculture

As a recent communications graduate, Lia Basden missed getting her hands dirty and making things grow. “My parents have a big garden and chickens,” she said.

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 Illino

Antibiotic resistance in human and animal health is on the forefront of public debate, but it’s a less well-known issue in plant agriculture. However, antibiotics are important tools in fruit production, and their efficacy hinges on avoiding resistance in disease-causing bacteria. 

Scientists at the University of Illinois Urbana-Champaign can now differentiate between human-derived and hydrological contributions of riverine nitrogen pollution in the Upper Mississippi River Basin.

University of Illinois Urbana-Champaign corn breeders know profitability is about more than yield.

Bathed in an otherworldly purple glow, James Santiago points to a curled leaf at the base of a spinach plant. “This is an issue we saw all the time at the vertical farm where I worked in Virginia. We don't know exactly what's going on, but I think it has something to do with water stress, which is weird because the plants are growing in water.”

The energy that plants capture from sunlight through photosynthesis provides the source of nearly all of humanity’s food. Yet the process of photosynthesis has inefficiencies that limit crop productivity, especially in a rapidly changing world. A new review by University of Illinois scientists and collaborators reflects on how improving photosynthesis can bring us closer to food security.

The U.S. is largely self-sufficient in agricultural food production, supported by a well-developed storage and interstate trade system. However, extreme weather events put increasing pressure on agriculture, potentially impacting the country’s ability to provide food for its growing population and underscoring the importance of maintaining a resilient food supply chain. 

Cover crops improve soil health and water quality, prevent nutrient loss, and reduce greenhouse gas emissions, but they’re only grown on about 5% of U.S. agricultural lands. That’s despite billions in annual federal investments, primarily in the form of cost-share and incentive payments to farmers who adopt conservation practices.   

A new study from the Agroecosystem Sustainability Center (ASC) of the University of Illinois Urbana-Champaign provides one of the most comprehensive explanations to date of how tile drainage, a common agricultural practice, enhances the functioning of agricultural landscapes. Although tile drainage has been widely studied as an important form of agricultural infrastructure, the new study built a comprehensive framework to explain why tile drainage is so effective across a wide range of outcomes.
