Midwestern beef production works just as well off pasture
URBANA, Ill. – Beef producers in the upper Midwest know grazing land is in short supply. With more acres being developed or converted to cropland, producers who want to expand their cow-calf operations are looking for alternatives to traditional pasture management.
Researchers find tradeoff between water quality and emissions on the farm
URBANA, Ill. – With water quality guidelines compelling more farmers to act on nitrogen loss, cover crops and split nitrogen applications are becoming more common in the Midwest. But new University of Illinois research shows these conservation practices may not provide environmental benefits across the board.
Powerful sensors on planes detect crop nitrogen with high accuracy
URBANA, Ill. – Synthetic nitrogen fertilizers transformed agriculture as we know it during the Green Revolution, catapulting crop yields and food security to new heights. Yet, despite improvements in crop nitrogen use efficiency, fears of underperformance spur fertilizer overapplication to this day. Excess nitrogen then ends up in waterways, including groundwater, and in the atmosphere in the form of potent greenhouse gases.
Microbe sneaks past tomato defense system, advances evolutionary battle
URBANA, Ill. – When we think of evolution, many of us conjure the lineage from ape to man, a series of incremental changes spanning millions of years. But in some species, evolution happens so quickly we can watch it in real time.
Study clarifies nitrogen’s impact on soil carbon sequestration
URBANA, Ill. – Soil organic carbon is a cornerstone of soil health. It improves soil structure while enhancing water- and nutrient-holding capacity, key factors for any agricultural production system. To build it up, farmers incorporate crop residues into soils.
So why, despite decades of residue inputs, is soil organic carbon diminishing in corn production systems? Short answer: it’s the nitrogen.
Tanzania field trial finds soil testing and subsidies can increase fertilizer use and maize yields
URBANA, Ill. – The right mineral fertilizers applied appropriately can alleviate nutrient deficiencies in soils and increase crop yields, but most small-scale farmers in Sub-Saharan Africa do not have their soils tested to reveal these deficiencies.
Illinois AgrAbility celebrates 30 years of helping farmers, families
Urbana, Ill. – Illinois AgrAbility proudly acknowledges 30 years of service to Illinois agricultural producers. The program provides assistance to Illinois farmers with physical limitations and disabilities so they can maintain their independence and continue farming.
Resolute scientific work could eliminate wheat disease within 40 years
URBANA, Ill. – Wheat and barley growers know the devastating effects of Fusarium head blight, or scab. The widespread fungal disease contaminates grain with toxins that cause illness in livestock and humans, and can render worthless an entire harvest. As Fusarium epidemics began to worsen across the eastern U.S. in the 1990s and beyond, fewer and fewer farmers were willing to risk planting wheat.
First dicamba-resistant waterhemp reported in Illinois
URBANA, Ill. – University of Illinois weed scientists have confirmed resistance to the herbicide dicamba in a Champaign County waterhemp population. In the study, dicamba controlled 65% of the waterhemp in the field when applied at the labeled rate. And in the greenhouse, plants showed a 5-to-10-fold reduction in dicamba efficacy compared with sensitive plants.
ACES researchers named on international ‘Highly Cited’ list
URBANA, Ill. — Two ACES researchers are amongst 6,600 researchers around the world recognized by Clarivate as Highly Cited Researchers. The highly anticipated annual list helps define the “who’s who” of influential researchers based on data and analysis performed by experts and data scientists at the Institute for Scientific Information at Clarivate.
