摘要：
The invention relates to a method for producing a lignin-based substrate for soil improvement having a water-storing property, characterized by the following steps: providing lignin, oxidizing the lignin in either an aqueous alkaline suspension or a pH-neutral aqueous suspension, the pH-neutral aqueous suspension being converted into an alkaline substance after the lignin has been oxidized, cross-linking the lignin in an aqueous alkaline medium using multifunctional compounds, and neutralizing, drying, and comminuting the lignin.
