Iowa Learning Farms Webinar: Recycling Nutrients from Hog Manure Using Biochar and Zeolite


AMES, Iowa – The Iowa Learning Farms Conservation Webinar taking place May 25 at noon CDT will feature Iowa State University environmental researchers Chumki Banik and Santanu Bakshi.

Banik and Bakshi are collaborating on research on the management and use of manure as organic fertilizer in ways that improve soil health while limiting nutrient loss to waterways. Their work includes evaluating the impacts of biochar-manure mixtures on the physical and chemical structure of agricultural soils. Additionally, their current research focuses on using zeolite, a highly absorbent mineral, and biochar to concentrate and recover nutrients from pig manure for efficient recycling back to cropland while reducing nutrient leakage and improving air quality in the pig production system.

Iowa Learning Farms is a conservation and water quality education program at Iowa State University Extension and Outreach.

In the webinar, “Using Biochar and Zeolite to Recycle Phosphorus and Nitrogen from Pig Manure: An Integrative Approach,” Banik and Bakshi will discuss the effectiveness of using biochar and biochar mixtures. zeolite to help recover nitrogen and phosphorus from pig manure. They will also highlight the potential environmental and economic benefits and impacts of agroecosystems that use organic fertilizer processes such as those currently under investigation.

“We anticipate that this study will provide significant data and results to help identify potential positive impacts on climate change mitigation strategies, reduction of pollutants in natural water bodies, and long-term sustainability of a wide range of farming systems,” Banik said. “This study should also help inform and encourage farmers about the positive economic and environmental benefits of using sustainable organic fertilizer methods.”

Attendees of Iowa Learning Farms conservation webinars are encouraged to ask questions of the presenters. People from all walks of life and all areas of interest are encouraged to join.
