Engineers develop ‘bury-and-forget’ sensors, data networks for better soil, water quality

By Mike Krapfl, Iowa State University News Service

Iowa State’s Jonathan Claussen, an assistant professor of mechanical engineering, is leading a team of engineers developing a system of low-cost, “bury-and-forget” soil sensors connected to a remote, wireless, data-collection network. Data collected by the system will help the engineers build better models of the interactions of fertilizer, soil and crops. Those models could help…
