Three commercially available tree stump removal products: Dexol Stump Remover, Cooke Stump Remover & Potassium Nitrate, and Lily/Miller Stump Remover and Potassium Nitrate, as well as three nitrogen-containing fertilizers—potassium nitrate (13-0-45), ammonium nitrate (34-0-0), and ammonium sulfate (21-0-0), were evaluated for their ability to hasten decomposition of the stumps of two tree species [Eucalyptus camaldulensis Dehnh. and Paulownia tomemtosa (Thunb.) Steud.]. None of the products accelerated decay in either species after 8 weeks.
