URBANA, Ill. -- The growing threat of drought and rising water demand have made accurate forecasts of crop water use critical for farmland water management and sustainability. But limitations in existing models and satellite data pose challenges for precise estimates of evapotranspiration — a combination of evaporation from soil and transpiration from plants. The process is complex and difficult to model, and existing remote-sensing data can’t provide accurate, high-resolution information on a daily basis.

CHAMPAIGN, Ill. —  Like many industries, big data is driving innovations in agriculture. Scientists seek to analyze thousands of plants to pinpoint genetic tweaks that can boost crop production—historically, a Herculean task. To drive progress toward higher-yielding crops, a team from the University of Illinois is revolutionizing the ability to screen plants for key traits across an entire field.

URBANA, Ill. – Edamame may be a niche crop in the United States, but growers and processors still need the best possible information to make sound management decisions. That’s why USDA Agricultural Research Service (USDA-ARS) and University of Illinois researchers are making new plant density recommendations for machine-harvested edamame, at less than half the rate suggested by seed companies.

URBANA, Ill. – Like most invasive species, when the soybean aphid arrived in the Midwest in 2000, it brought none of its natural enemies along for the ride. So, naturally, finding itself in the soybean capital of the world, the tiny insect went bonkers. Taking advantage of a nifty ability to reproduce without mating, populations exploded and the soybean aphid quickly became the number one insect pest affecting the crop.

URBANA, Ill. — A diet including daily avocado consumption improves the ability to focus attention in adults whose measurements of height and weight are categorized as overweight or obese, a new randomized control trial found. Researchers at the University of Illinois at Urbana-Champaign conducted the 12-week study, published in the International Journal of Psychophysiology. Read more.

URBANA, Ill. – Cattle feeders choose distillers grains in feedlot diets as an inexpensive alternative to corn and soybean meal. But until now, no one had studied the effects of the common feed ingredient on bull development and fertility. With bull fertility to blame for a significant portion of reproductive failures in cow-calf operations, University of Illinois researchers decided it was worth a look.

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.

URBANA, Ill. — Being distracted by technology during mealtime may decrease the amount of food a person eats, nutrition scientists suggest in a new study.

When 119 young adults consumed a meal while playing a simple computer game for 15 minutes, they ate significantly less than when they ate the same meal without distractions, said lead author Carli A. Liguori.

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.  

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.
