The acceleration of the possibility of the composting process of plant waste with mineral additives has been studied. The proposed method has proven itself during both thermophilic and mesophilic composting. There was no change in the ripening period of the compost obtained with the presence of mineral additives compared to the microbiological fertilizers. The received organic mineral fertilizers were enriched with a fairly high amount of nitrogen, phosphorus, potassium, and magnesium compounds.
