Jarrod O. Miller

Jarrod O. Miller is an Associate Professor and Extension Specialist in Agronomy at the Department of Plant and Soil Sciences, University of Delaware. He holds a Ph.D. in Soil Science from the University of Kentucky and focuses on improving agronomic yields through economically efficient and environmentally sustainable practices.

• Ph.D. – Soil Science – University of Kentucky (2008)
• M.S. – Crop and Soil Environmental Sciences – Virginia Tech (2002)
• B.S. – Environmental Science – Virginia Tech (1999)

His research emphasizes precision agriculture technologies, including drones (UAV), variable rate equipment, sensors, and yield monitors, to enhance farm efficiency. He also studies saltwater intrusion and soil salinization on the Delmarva Peninsula, aiming to develop management strategies for coastal agricultural systems. Additional work explores nitrogen cycling in wetlands, biochar applications for soil fertility, and carbon sequestration in reclaimed mine soils.

Recent publications highlight his work on Mehlich-3 extractable sodium for salinity detection, drone-based multispectral imaging for cover crop nitrogen content, and soybean planting date effects on yield and nutrient concentrations. These studies reflect his commitment to integrating technology with soil health management.

Mills teaches courses like PLSC304 – Soil Fertility and Plant Nutrition Lab and PLSC305 – Soil Fertility and Plant Nutrition. He collaborates with institutions such as the USDA-ARS and Virginia Tech, and his projects are sponsored by organizations including the Delaware and Maryland Soybean Boards. His extension outreach includes the Delmarva Saltwater Intrusion initiative and drone-based agronomic recommendations.
