A method for restoring a contaminated site comprising the steps of: undertaking an amendment of a contaminated site by applying a first catalyst and a second catalyst to the contaminated site; and incorporating the first catalyst and the second catalyst into a soil on the contaminated site to form an amended contaminated site, wherein the contaminated site has excessive acidity, alkalinity and/or sodic contamination, wherein amending the contaminated site with the first catalyst and the second catalyst assists in the restoration of the amended contaminated site by transferring a biological energy generation mechanism to the amended contaminated site which improves the capacity of the amended contaminated site to balance a hydrogen cycle and hydrogen exchange between biotic and abiotic sources.
