FIELD: chemistry.
SUBSTANCE: invention relates to agriculture. The method of producing organomineral fertiliser from sewage sludge by composting, wherein sewage sludge is mixed with sawdust (wood processing wastes) in ratio of 1:0.12 by weight or 1:0.61 by volume, or with shredded straw in ratio of 1:0.11 by weight or 1:1.82 by volume, and potassium sulphate is then added to said mixture in amount of 0.2-0.3% by weight of the substrate, followed by composting in piles.
EFFECT: invention simplifies and reduces the cost of producing organomineral fertiliser and increases fertilising value of the end product.
