    The Department of Environment, Great Lakes, and Energy (EGLE) encourages the use of Biosolids (also known as sewage sludge) to enhance agricultural and silvicultural production in Michigan. Almost all Biosolids that are land applied in Michigan are used to grow crops on sites at agronomic application rates approved by the EGLE. Biosolids are also used to provide nutrients and soil conditioning in mine reclamation programs, tree farms, and forest lands.
