FIELD: chemistry.
SUBSTANCE: invention relates to agriculture and a method of preparing an organomineral fertiliser mixture. Sewage sludge is mixed with a detoxicant. The detoxicant used is sodium humate in form of a finely dispersed fraction with particle size of not more than 100 mcm in amount of not less than 10% of the weight of the sludge.
EFFECT: invention increases effectiveness of using sewage sludge as fertiliser owing to reduction of content of heavy metals.
