Research summary

Chad J. Penn studies how phosphorus and other nutrients move through soils, wetlands, and agricultural drainage systems, and how to prevent excess nutrients from polluting waterways such as Lake Erie. His work includes testing materials and structures (like iron-based filters) that remove phosphorus from water, and examining soil chemistry and plant-fungal interactions that affect nutrient availability. Much of this research aims to help manage farmland in ways that reduce nutrient runoff into rivers and lakes.
