From AI-powered beekeeping tools to antibiotic alternatives to plant-based defense against heart disease, the 1890 land-grant system to tackling some of the most pressing challenges in agriculture and human health.
By the 1890 Land-Grant Universities — summarized for agInnovation
The second batch of highlights from the 2026 1890 Land-Grant Universities Impact Report moves from crops to the living systems that surround him—pollinators, livestock, soil, and ultimately people. The through-line is resilience: research that strengthens agriculture against threats old and new, and that connects what happens on the farm to what ends up on our plates and in our bodies.
Central State University: Bee Strong
Pollinators support roughly one-third of the global food supply, and honeybees are at the center of that system—and under serious pressure. Central State University researchers tackled one of beekeeping's most destructive threats: the Varroa destructor mite, which decimates colonies worldwide.
Through selective breeding, they developed honeybee stocks with enhanced grooming and mite-biting traits, then created advanced imaging tools and a smartphone app that allows beekeepers to identify mite-resistant colonies with more than 90% accuracy.
Field studies found that feral honeybees in Ohio and Kentucky exhibit 34% to 49% higher mite-biting behavior than commercial bees—a reservoir of natural resilience that the team is now working to harness. The research also advanced molecular resources for wild pollinators, including the small carpenter bee, a critical native pollinator for fruits, vegetables, and biofuel crops. This is genetics, technology, and ecology working together in service of American food security.
Alcorn State University: Smarter Watermelon Fields
Graduate student TreDarious Clifton wanted to know whether planting pollinator-friendly flowering species alongside watermelon crops could improve yields—and the answer was yes.
Using a Randomized Complete Blog Design at Alcorn State's Model Farm and Experiment Station, Clifton compared traditional watermelon plots with intercropped plots and found that intercropped fields attracted significantly more pollinators and produced higher fruit yields. It's a practical low-cost strategy for small and mid-sized farmers that addresses one of American agriculture's most pressing long-term challenges: the decline of pollinators. Two-thirds of global crops depend on pollinators, and as that foundation weakens, so does the food system built on top of it. Clifton's work shows that sustainability and productivity don't have to be in conflict.
University of Arkansas at Pine Bluff: National Solutions for Healthier Sheep
Antibiotic overuse in livestock is a growing crisis for farmers watching treatments lose effectiveness, for consumers worried about residues in food, and for public health officials tracking the rise of antimicrobial resistance.
The University of Arkansas at Pine Bluff is testing a natural alternative: a two-year study evaluating sericea lespedeza and walnut hull powder as dietary supplements that enhance sheep’s innate immunity and gastrointestinal health, reducing the need for conventional antibiotics and de-wormers.
Fewer chemical inputs means cleaner food. It also means American producers can better compete in markets that increasingly demand naturally raised products, positioning U.S. farmers at the forefront of sustainable livestock innovation.
Southern University Ag Center: Proper Livestock Management Boosts Soil Health
Grazing lands cover 55% of all privately owned land in the United States, yet research on their role in soil health had been remarkably limited. The Southern University Ag Center conducted one of the first U.S. studies focused specifically on grazing lands, running a four-year project at three privately owned farms in south Louisiana.
Using a 30-day rest-rotation grazing schedule, the team measured soil organic matter, forage productivity, pasture quality, and botanical composition. The findings confirmed significant increases in soil organic matter, which boosts nitrogen availability and accelerates plant growth.
It’s foundational work: understanding how America’s vast grazing lands function is essential to managing them for both productivity and long-term sustainability.
North Carolina A&T State University: Fighting Heart Disease With Food Science
Heart disease is the leading cause of death in America, costing more than $400 billion annually in healthcare and lost productivity. NC A&T food scientist Shengmin Sang, Ph.D., has received one of the most competitive grants offered by the National Institutes of Health to investigate how flavonoids (the antioxidant compounds found in apples, blueberries, soy milk and green tea) may reduce carbonyl stress, a specific physiological marker linked to cardiovascular disease.
His three-week dietary trial will measure how flavonoid-rich foods affect stress biomarkers at the molecular level, potentially identifying a new, measurable early warning sign for heart disease risk.
“We know that plant-based foods are linked to a reduced risk of cardiovascular disease, but the internal mechanisms of how they work are still unclear,” Sang said. “For this project, we want to provide scientific evidence that links plant-based food to the prevention of cardiovascular disease.” This is agricultural science doing exactly what it was built to do: serving human health.
These five stories are drawn from the 2026 1890 Land-Grant Universities Impact Report, a document that makes a compelling case for why this network of institutions, and the public funding that sustains them, matters deeply.
