Advanced model and field data add up to better cover crop management

URBANA, Ill. – Cover crops are widely seen as one of the most promising conservation practices, improving soil health while also removing carbon from the atmosphere. But while the number of Midwestern farmers planting cover crops has increased markedly in recent years, 2017 USDA Census data show only about 5% have adopted the conservation practice. The reluctance of the other 95% may be due, in part, to a perception that cover crops require more effort and may also negatively affect summer cash crop yield.

$25M tech grant lets Illinois researchers ‘talk’ to plants

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.

Think climate change is bad for corn? Add weeds to the equation

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.

Marginal land available for bioenergy crops much scarcer than previously estimated

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.

Dynamic photosynthesis model simulates 10-20 percent yield increase

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.

Herbicide resistance no longer a black box for scientists

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.

Some birds steal hair from living mammals

URBANA, Ill. -- Dozens of online videos document an unusual behavior among tufted titmice and their closest bird kin. A bird will land on an unsuspecting mammal and, cautiously and stealthily, pluck out some of its hair.

New modeling solution sets bar for quantifying carbon budget and credit

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.
