This study evaluated the effect of the use of sewage sludge in nature on biological soil parameters. The study was conducted is field experiment environment (small beds). The sandy soil was fertilized with sewage sludge dried naturally (in heaps) and in solar drying facilities. The fertilization was based on the doses of sewage sludge and manure with the amounts of 10, 20, 30 and 40 Mg/ha. The experiment duration was 3 years. The sanitary status of the soils fertilized with the sludge and

Furthermore, the content of pathogenic bacteria was evaluated, with determination of its resistance to first-line antibiotics. Material and research methodology Sewage sludge from the wastewater treatment plant in Myszków, Poland, was used as a fertilizer to perform a field experiment. After dehydration (with addition of
