Photosynthesis varies greatly across rice cultivars — natural diversity could boost yields

CHAMPAIGN, Ill. —  Rice is a direct source of calories for more people than any other crop and serves as the main staple for 560 million chronically hungry people in Asia. With over 120,000 varieties of cultivated rice (Oryza sativa) across the globe, there is a wealth of natural diversity to be mined by plant scientists to increase yields.

Corn productivity in real time: Satellites, field cameras, and farmers team up

URBANA, Ill. – University of Illinois scientists, with help from members of the Illinois Corn Growers Association, have developed a new, scalable method for estimating crop productivity in real time. The research, published in Remote Sensing of Environment, combines field measurements, a unique in-field camera network, and high-resolution, high-frequency satellite data, providing highly accurate productivity estimates for crops across Illinois and beyond.

Illinois study shows universally positive effect of cover crops on soil microbiome

URBANA, Ill. – Only a fraction of conventional row crop farmers grow cover crops after harvest, but a new global analysis from the University of Illinois shows the practice can boost soil microbial abundance by 27%.

The result adds to cover crops’ reputation for nitrogen loss reduction, weed suppression, erosion control, and more. Although soil microbial abundance is less easily observed, it is a hugely important metric in estimating soil health.

Boost soybean yields by adapting photosynthesis to fleeting shadows, according to model

Komorebi is a Japanese word that describes how light filters through leaves—creating shifting, dappled “sunflecks” that illustrate plants’ ever-changing light environment. Crops harness light energy to fix carbon dioxide into food via photosynthesis. In a special issue of Plant Journal, a team from the University of Illinois reports a new mathematical computer model that is used to understand how much yield is lost as soybean crops grapple with minute-by-minute light fluctuations on cloudy and sunny days.

New artificial intelligence algorithm better predicts corn yield

URBANA, Ill. – With some reports predicting the precision agriculture market will reach $12.9 billion by 2027, there is an increasing need to develop sophisticated data-analysis solutions that can guide management decisions in real time. A new study from an interdisciplinary research group at University of Illinois offers a promising approach to efficiently and accurately process precision ag data.

Harrington Seed Destructor kills nearly 100% of U.S. agronomic weed seeds in lab study

URBANA, Ill. – In the battle against herbicide-resistant weeds, farmers are increasingly eager to add non-chemical control methods to their management toolbox. Impact mills, which destroy weed seeds picked up by a combine, have been shown to kill 70-99% of weed seeds in soybeans, wheat, and other small-statured cropping systems.

Chinese tariff rate quota policy severely impacted U.S. wheat exports, study shows

URBANA, Ill. – The U.S. and China recently agreed to a phase one trade deal that aims to resolve the current trade war between the two countries. But that is just the latest development in longstanding and complicated U.S.-Chinese trade disputes.

DOE project at U of I will measure bioenergy crop carbon emissions

The U.S. Department of Energy has awarded a $3.3 million grant to a multidisciplinary research team at the University of Illinois at Urbana-Champaign to develop a precise system for measuring greenhouse gas emissions from commercial bioenergy crops grown in central Illinois.

Nanosatellites improve detection of early-season corn nitrogen stress

URBANA, Ill. – For corn growers, the decision of when and how much nitrogen fertilizer to apply is a perennial challenge. Scientists at the University of Illinois have shown that nanosatellites known as CubeSats can detect nitrogen stress early in the season, potentially giving farmers a chance to plan in-season nitrogen fertilizer applications and alleviate nutrient stress for crops.
