Richard Cruse is an Agronomy professor at Iowa State University. His research focuses on soil and crop management. One of his most recent projects involved leading a research team that created a system to more realistically estimate the amount of soil erosion occurring in Iowa. Cruse talked with Iowa Environmental Focus about this project, and about the importance of preserving Iowa’s topsoil.
