DISPOSAL OF CORN ASH

A plan for proper disposal of corn ash needs to be developed before purchasing a corn-burning stove or boiler. Burning shelled corn yields less ash residue than burning firewood or cinders from burning coal. Corn ash has some modest value as a fertilizer and as a liming agent, with no evidence of heavy metals or any other contaminants. The corn ash (after cooling) can be safely applied to garden areas, flower beds, lawns, and fields.
