A renewed national interest in energy issues emphasizes some of the AFSRC’s history of groundbreaking research on the safe and efficient use of coal combustion by-products as soil amendments. This vintage photo shows a former support scientist and Mr. C. E. Lynch, Biological Science Technician, collecting samples from lysimeters used to study coal combustion by-products used as soil amendments. AFSRC scientists are still researching uses for coal combustion by-products by developing and testing approaches to modifying the rhizosphere through constructed soils utilizing agricultural and/or industrial by-products as amendments for amenity grasses
