Andrew J. Margenot

Assistant Professor

Dr. Margenot addresses the literal foundation of all cropping systems: soils. He is advancing how we monitor and manage soils as natural capital. His research team evaluates how human activities can enhance or compromise soil services to human societies, with an emphasis on food security from urban and rural agroecosystems in the U.S. Midwest and East Africa.
