URBANA, Ill. – Construction on the University of Illinois’ new Feed Technology Center may be complete, but donations are still arriving to sponsor the facility’s $20 million price tag. For Ed McMillan and his family, the first individual donors, the choice to give to the Feed Technology Center was simple.

URBANA, Ill. – Dairy producers know early nutrition for young calves has far-reaching impacts, both for the long-term health and productivity of the animals and for farm profitability. With the goal of increasing not just body weight but also lean tissue gain, a new University of Illinois study finds enhanced milk replacer with high crude-protein dry starter feed is the winning combination.  

URBANA, Ill. – Soil erosion is a major challenge in agricultural production. It affects soil quality and carries nutrient sediments that pollute waterways. While soil erosion is a naturally occurring process, agricultural activities such as conventional tilling exacerbate it. Farmers implementing no-till practices can significantly reduce soil erosion rates, a new University of Illinois study shows.

URBANA, Ill. – Large perennial grasses like miscanthus are a primary target for use as bioenergy crops because of their sustainability advantages, but they take several years to establish and aren’t ideal for crop rotation. Maize and other annual crops are easier to manage with traditional farming, but they are tougher on the environment.

Energy sorghum, a hefty annual plant with the ecological benefits of a perennial, may combine the best of both crops.

URBANA, Ill. – Scientists are getting closer to finding the genes for maleness in waterhemp and Palmer amaranth, two of the most troublesome agricultural weeds in the U.S.

Finding the genes could enable new “genetic control” methods for the weeds, which, in many places, no longer respond to herbicides.

URBANA, Ill.  – Smallholder farmers in Sub-Saharan Africa use fertilizer well below recommended rates, contributing to consistently low agricultural productivity. Farmers in Tanzania and Kenya, for example, apply just 13 kilograms of fertilizer per hectare, compared with 165 to 175 kilograms in India and Brazil. Low use directly affects cereal yields, which average 1.2 to 1.7 metric tons per hectare, compared to 4 to 4.5 metric tons in South America and Asia.

URBANA, Ill. – The Natural Resources Conservation Service (NRCS), part of the U.S. Department of Agriculture, has awarded $1.12 million to support University of Illinois-led research to clean agricultural drainage water through saturated buffers and denitrifying bioreactors. The investment, part of NRCS’s Conservation Innovation Grant (CIG) program, was matched by numerous stakeholder partners in Illinois, Iowa, and Minnesota, for a total of nearly $2.25 million. 

CHAMPAIGN, Ill. — Carbon dioxide fuels photosynthesis, the process by which plants generate their food in the form of carbohydrates. The atmosphere’s carbon dioxide levels are rapidly increasing, but there is uncertainty about whether plants can turn these extra resources into higher yields while retaining nutritional quality. 

URBANA, Ill. -- The U.S. backs out of the Paris climate agreement even as carbon dioxide (CO₂) levels continue to rise. Through photosynthesis, plants are able to turn CO₂ into yield. Logic tells us that more CO₂ should boost crop production, but a new review from the University of Illinois shows that some crops, including corn, are adapted to a pre-industrial environment and cannot distribute their resources effectively to take advantage of extra CO₂.

CHAMPAIGN, Ill. — Five years ago, the United Nations committed to achieving the Sustainable Development Goal of Zero Hunger by 2030. Since then, however, world hunger has continued to rise. Nearly 9 percent of our global population is now undernourished, according to a 2020 report from the FAO, and climate variability is a leading factor driving us off course.
