URBANA, Ill. – Farmers in Sub-Saharan Africa use fertilizer well below recommended rates for optimal productivity. One reason is lack of trust in the products available from local agri-dealers, says Hope Michelson, professor in the Department of Agricultural and Consumer Economics (ACE) at University of Illinois.

URBANA, Ill. – The National Science Foundation (NSF) announced today an investment of $25 million to launch the Center for Research on Programmable Plant Systems (CROPPS). The center, a partnership among the University of Illinois at Urbana-Champaign, Cornell University, the Boyce Thompson Institute, and the University of Arizona, aims to develop tools to listen and talk to plants and their associated organisms.

URBANA, Ill. – By the end of the century, scientists expect climate change to reduce corn yield significantly, with some estimating losses up to 28%. But those calculations are missing a key factor that could drag corn yields down even further: weeds.

Wetter springs and hotter, drier summers, already becoming the norm in the Corn Belt, put stress on corn during key reproductive stages, including silking and grain fill. But those same weather conditions can benefit the scrappy weeds that thrive in tough environments.

URBANA, Ill. -- Land is the planet’s limiting resource. We need land for food, biofuel, feed, ecosystem services, and more. But all land is not equal. Concerns about diverting land under food/feed crops to biofuel feedstocks have led to interest in using marginal land to produce these dedicated bioenergy crops for advanced biofuels. Marginal land has typically been defined as land that is of low quality and not in food crop production.

URBANA, Ill. ­– Most scientists agree climate change has a profound impact on U.S. agricultural production. But estimates vary widely, making it hard to develop mitigation strategies. Two agricultural economists at the University of Illinois take a closer look at how choice of statistical methodology influences climate study results. They also propose a more accurate and place-specific approach to data analysis.

CHAMPAIGN, Ill. —  Plants use sunlight to generate their food through photosynthesis. When the sun rises each morning, plants must prepare themselves to receive nutrients from the sunlight, which takes time. Decreasing the prep time in plants could hold the key to improving yields in many crop varieties.

URBANA, Ill. – When he thinks about where he’ll be in five to 10 years, recent University of Illinois graduate Austin Parish sees himself disrupting the agriculture industry. In a good way.

“Right now, our only limitation in ag is how big we can think. I'm excited to be working alongside startups to bring more data and technology than ever to disrupt the plant biotechnology space,” he says.

URBANA, Ill. – When agricultural weeds evolve resistance to herbicides, they do it in one of two ways. In target-site resistance, a tiny mutation in the plant’s genetic code means the chemical no longer fits in the protein it’s designed to attack. In non-target-site resistance, the plant deploys a whole slew of enzymes that detoxify the chemical before it can cause harm.

URBANA, Ill. -- Carbon is everywhere. It’s in the atmosphere, in the oceans, in the soil, in our food, in our bodies. As the backbone of all organic molecules that make up life, carbon is a very accurate predictor of crop yields. And soil is the largest carbon pool on earth, playing an important role in keeping our climate stable. 

As such, computational models that track carbon as it cycles through an agroecosystem have massive untapped potential to advance the field of precision agriculture, increasing crop yields and informing sustainable farming practices.

URBANA, Ill. – Ask a farmer, a scientist, and a conservation professional to define soil health, and you might come up with three rather different answers. That mismatch may be at the root of lower-than-ideal adoption of soil conservation practices, according to a new study from the University of Illinois and The Ohio State University.
