URBANA, Ill. – The University of Illinois has been awarded $4.5 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) through its “Systems for Monitoring and Analytics for Renewable Transportation Fuels from Agricultural Resources and Management” (SMARTFARM) program. The funding will be used to calculate farm-scale carbon credits, allowing individual farmers to understand the value of their land and practices towards carbon trading markets.

URBANA, Ill. – Representing some of the most troublesome agricultural weeds, waterhemp, smooth pigweed, and Palmer amaranth impact crop production systems across the U.S. and elsewhere with ripple effects felt by economies worldwide. In a landmark study, scientists have published the most comprehensive genome information to date for all three species, marking a new era of scientific discovery toward potential solutions.   

URBANA, Ill. – In its 63rd year, Agronomy Day at the University of Illinois will be an event unlike any other. For the first time, due to the COVID-19 pandemic, the event moves online and features recorded video presentations from College of Agricultural, Consumer and Environmental Sciences (ACES) researchers and Extension specialists.

CHAMPAIGN, Ill. — Crops grow dense canopies that consist of several layers of leaves—the upper layers with younger sun leaves and the lower layers with older shaded leaves that may have difficulty intercepting sunlight trickling down from the top layers.

URBANA, Ill. – Conventional agriculture relies on the application of phosphorus from fertilizers or animal manure to deliver adequate amounts of the essential element to growing crops for maximum productivity. However, unintended losses of phosphorus from fields to water bodies can impact aquatic ecosystems.

A University of Illinois study reveals soil phosphorus concentrations can vary greatly across a single field translating to sub-field variability of dissolved phosphorus, a readily available form promoting algal production, in tile (artificial subsurface drainage) water.

URBANA, Ill. – The Soybean Innovation Lab (SIL) developed a new Guide to African Soybean Seedborne Diseases and Pests for use by African seed companies, seed multipliers, research institutions, and soybean processors, whose operations demand high-quality seed. Identifying the causes of decreased seed health, which translates to poor germination, low yields, and decreased profitability, is key to building a successful soybean industry in Africa.

URBANA, Ill. – As climate change becomes increasingly difficult to ignore, scientists are working to diversify and improve alternatives to fossil-fuel-based energy. Renewable bioenergy crops, such as the perennial grass Miscanthus, show promise for cellulosic ethanol production and other uses, but current hybrids are limited by environmental conditions and susceptibility to pests and diseases.

URBANA, Ill. – Genetically speaking, the loaf of bread you stress-baked during the COVID-19 shutdown is more complex than you think. Wheat’s 16 billion genes, organized in not one but three semi-independent genomes, can overlap or substitute for one another, making things extremely tricky for geneticists trying to enhance desirable traits in the world’s most widely grown crop.

CHAMPAIGN, Ill. — The crops we grow in the field often form dense canopies with many overlapping leaves, such that young “sun leaves” at the top of the canopy are exposed to full sunlight with older “shade leaves” at the bottom. In order to maximize photosynthesis, resource-use efficiency, and yield, sun leaves typically maximize photosynthetic efficiency at high light, while shade leaves maximize efficiency at low light. 

URBANA, Ill. – Like antibiotic-resistant bacteria, some herbicide-resistant weeds can’t be killed by available chemicals. The problem affects more than just the errant weed in our driveways; herbicide-resistant weeds threaten our food supply, stealing resources and outcompeting the crops that make up our breakfast cereal and feed the nation’s livestock.

The weed that represents the biggest threat to Midwestern corn and soybean production, waterhemp, has outsmarted almost every kind of herbicide on the market today.
