Abstract

The present invention relates to the field of producing humic acids from peat by using alkaline extraction of them with potassium carbonate. The amount of peat is treated with oxidising agent giving oxygen during extraction-process. 2,5-10% solution of potassium carbonate is used for extraction at the temperature of 60 to 100 C.
