A method utilizing a humic acid substance for renovating and afforsesting slag is provided. A humic acid substance may be utilized for passivation, adsorption, reduction, chelation and immobilization of harmful heavy metal elements in slag, for example, Cr, As, Cd, Ni, Pb, Ba, Hg, Co, Se, Ag and Be, and aggregating the slag, thereby detoxifying the slag and producing artificial earth. The artificial earth may be used in combination with a carrier bacterial fertilizer to continuously produce the active humic acid substance, achieving an effect similar to the combination of blood transfusion and blood production, thereby forming a high-quality artificial soil.
