Illinois, Nebraska scientists propose improvements to precision crop irrigation
URBANA, Ill. – With threats of water scarcity complicating the need to feed a growing global population, it is more important than ever to get crop irrigation right. Overwatering can deplete local water supplies and lead to polluted runoff, while underwatering can lead to sub-optimal crop performance. Yet few farmers use science-based tools to help them decide when and how much to water their crops.
Incentives could turn costs of biofuel mandates into environmental benefits
URBANA, Ill. -- New studies from the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) shed more light on the economic and environmental costs of mandates in the Renewable Fuels Standard (RFS), a federal program to expand the nation’s biofuels sector.
How the humble woodchip is cleaning up water worldwide
URBANA, Ill. – Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen in drainage water. Whether it flows out to the Great Barrier Reef or the Gulf of Mexico, the nutrient contributes to harmful algal blooms that starve fish and other organisms of oxygen.
In pig brain development, nature beats nurture
URBANA, Ill. – Before humans can benefit from new drug therapies and nutritional additives, scientists test their safety and efficacy in animals, typically mice and rats. But, as much as they’ve done for biomedical research, rodents aren’t always the best research model for studies on neonatal brain development and nutrition. That’s where pigs can play an important role.
New pig brain maps facilitate human neuroscience discoveries
URBANA, Ill. – When scientists need to understand the effects of new infant formula ingredients on brain development, it’s rarely possible for them to carry out initial safety studies with human subjects. After all, few parents are willing to hand over their newborns to test unproven ingredients.
Love bats? Think twice about that bat box, experts say
URBANA, Ill. – Ever thought about buying or building a bat box to help bats? Think carefully about the design and where you put it, University of Illinois researchers say.
Here’s why: Bats and their pups can overheat and die in poorly designed or placed bat boxes, and in a warming climate, it could happen more often.
Genome sequenced for pesky pumpkin pathogen
URBANA, Ill. – Pumpkin growers dread the tiny tan scabs that form on their fruit, each lesion a telltale sign of bacterial spot disease. The specks don’t just mar the fruit’s flesh, they provide entry points for rot-inducing fungus and other pathogens that can destroy pumpkins and other cucurbits from the inside out. Either way, farmers pay the price, with marketable yields reduced by as much as 90%.
Frequent fire too hot to handle for invasive plants
URBANA, Ill. – Land managers know one of the best ways to prevent forest fires is to set fires. Periodic controlled or prescribed burns can reduce the amount of flammable materials lying about on a forest floor, so when wildfires do start, they stay small.
Prescribed fires do more than that, though. New University of Illinois research shows frequent fires can help keep invasive plants in check by reducing nitrogen availability in soils.
Going back in time restores decades of quiet corn drama
URBANA, Ill. – Corn didn’t start out as the powerhouse crop it is today. No, for most of the thousands of years it was undergoing domestication and improvement, corn grew humbly within the limits of what the environment and smallholder farmers could provide.
Not just CO2: Rising temperatures also alter photosynthesis in a changing climate
URBANA, Ill. -- Agricultural scientists who study climate change often focus on how increasing atmospheric carbon dioxide levels will affect crop yields. But rising temperatures are likely to complicate the picture, researchers report in a new review of the topic.
