A nine-year study comparing a typical two-year corn and soybean rotation with a more intensive three-year rotation involving corn, cereal rye, soybean and winter wheat found that the three-year system can dramatically reduce nitrogen — an important crop nutrient — in farm runoff without compromising yield.

The new findings are detailed in the journal Frontiers in Environmental Science.

Weeds like Palmer amaranth make farming harder and less profitable, and available herbicides are becoming less effective. For scientists to find solutions, they first need to know their enemy.

There’s a longstanding attitude in many farming communities that trees and agriculture don’t mix. But agroforestry — the intentional integration of trees and shrubs in agricultural systems, such as planting trees as windbreaks, integrating trees on pastures, or growing tree crops intercropped with annual crops — can provide a multitude of benefits to both farmers and landscapes. So far, in the U.S. Midwest, these benefits have gone unrealized, with vanishingly small adoption rates.  

Yesterday, U.S. Representative Nikki Budzinski (IL-13) and the ITI Institute joined top researchers and policymakers at the University of Illinois Urbana-Champaign to see how AI is reshaping agriculture to address key challenges in food security, sustainability, and workforce development.

If corn was ever jealous of soybean’s relationship with nitrogen-fixing bacteria, advancements in gene editing could one day even the playing field.

Agricultural field trials can provide crucial information that helps scientists and farmers optimize production and reduce environmental impacts.

A team from the University of Illinois Urbana-Champaign has engineered potato to be more resilient to global warming, showing 30% increases in tuber mass under heatwave conditions. This adaptation may provide greater food security for families dependent on potatoes, as these are often the same areas where the changing climate has already affected multiple crop seasons.

Fungal contamination of cereal grains poses a substantial threat to food security and public health while causing hundreds of millions of dollars in economic losses annually.

A few years back, a group of weed scientists showed that soil-applied herbicides are less effective against agricultural weeds in the context of our changing climate.

Most corn and soybean fields in the U.S. are planted with herbicide-resistant crop varieties. However, the evolution of superweeds that have developed resistance to common herbicides is jeopardizing current weed management strategies. Agricultural robotics for mechanical weeding is an emerging technology that could potentially provide a solution.
