URBANA, Ill. – Cementing waterhemp’s reputation as a hard-to-kill weed in corn and soybean production systems, University of Illinois researchers have now documented the weed deviating from standard detoxification strategies to resist an herbicide that has never been commercialized.

URBANA, Ill. – The Feed the Future Innovation Lab for Soybean Value Chain Research (Soybean Innovation Lab, “SIL”) at the University of Illinois has been awarded $5 million by the United States Agency for International Development (USAID) to train and empower other Feed the Future Innovation Labs to achieve sustained impact from their innovations.

URBANA, Ill. – Machine learning can pinpoint genes of importance that help crops grow with less fertilizer, according to a new study published in Nature Communications.

URBANA, Ill. – While agrifood production is essential for feeding our growing global population, it can also contribute to environmental and social problems, including deforestation, biodiversity loss, poor or precarious labor conditions, and persistent poverty. Certification and standards can encourage use of sustainable production practices, but how effective are such programs in addressing food system challenges?

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.

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.
