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. – 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. – 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.

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. 

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.

URBANA, Ill. – Starting weanling pigs off with the right diet can make all the difference for the health and productivity of the animal. A new University of Illinois study shows amino acids from a new torula yeast product are more digestible by young pigs than amino acids from fish meal.
