Agriciltural microbiology| Резюме: | The complex of indicators of quality of sewage sludge (SS) of biological purification stations“Pivnichna” and “Pivdenna” of the City of Odessa was investigated for establishing a safe way of theirdisposal. It was established that these of SS are characterized by a number of positive features: they contain relatively small concentrations of pollutants, have a weakly acidic and acidic reaction of the medium,a wide Ca2+/Na+ratio in the salt composition, a high absorbent cationic capacity and saturation of absorbed complex with calcium ions; according to the fertilizer properties (in particular, the total nitrogencontent), they exceed traditional fertilizers and, according to agroecological assessments, are suitable foruse as fertilizers in the fields (after balancing them with the composition of the main nutrients and subjectto the recommended restrictions on the dose and frequency of application) and/or as local organic rawmaterial for processing it on the fertilizing biocompost (mixture) for use in agriculture |
