Iowa State researchers studying slow-release fertilizer to feed crops, improve water quality

By Mike Krapfl, Iowa State University News Service

A research project looking for ways to add value to biochar may have found an unexpected application for the black power that’s a co-product of thermochemically converting biomass to a liquid bio-oil. Iowa State University researchers have found biochar could be a slow-release fertilizer that delivers nutrients to crops while keeping those nutrients from washing away in the rain or leaching into groundwater. More uses for biochar could make thermochemical biofuel production a more economically attractive technology.
