The Ag Water Management research group at Iowa State University is a multi-tiered effort to study and analyze the impact of agricultural management practices on surface and subsurface drainage, from both a water quality and quantity perspective. The goal of this research is to study the fate and transport of water and contaminants on the agricultural landscape and to develop and promote practices that minimize water quality impacts of agricultural production. To accomplish our goals, the group uses field and lab research facilities, a university extension presence, and publications and presentations.

Why is our research important to you?

Agricultural water management incorporates both surface and subsurface drainage. Projects associated with water management through this research group focus on both environmental and agronomic impacts. Questions being investigated include: Is it possible to mitigate the impact cropping systems have on nitrate-nitrogen loss? If so, how? And, will mitigation techniques impact yield?
