Dr. Hanna Poffenbarger is an associate professor of soil nutrient management at University of Kentucky. She studies how carbon and nutrients cycle in cropping systems and uses this understanding to develop sustainable soil management practices and resilient production systems. Specific areas of interest include: nutrient capture and release by cover crops, spatiotemporal controls on nitrogen dynamics, optimal fertilization practices for crop yield and quality, and root impacts on soil organic matter formation and persistence. She also teaches Soil Nutrient Management to undergraduate and graduate students at University of Kentucky.
