摘要：

PROBLEM TO BE SOLVED: To effectively utilize unused resources by establishing a method of recovering industrially usable fulvic acid. SOLUTION: A fulvic acid-containing material is produced by a method including a step for bringing a fulvic acid-containing aqueous liquid into contact with activated carbon to cause the activated carbon to adsorb fulvic acid and a step for bringing the activated carbon which has adsorbed fulvic acid into contact with a warm alkaline aqueous liquid of 40-95°C as an eluent to elute fulvic acid.
