Description	Use of garden biowaste and sewage sludge for vermicomposting would be useful especially for smaller municipalities with waste water treatment plants. The study was focused on the evaluation of temperature, pH, electrical conductivity and two forms of mineral nitrogen during five-month vermicomposting of these types of waste. Garden biowaste and its mixtures with sewage sludge should be pre-composted to achieve temperature below 25°C. The pH value decreased during the process and ranged from 6.9 to 7.3 at the end of the experiment. Electrical conductivity increased from 1.6 to 2.7 mS/cm to the range between 3.0 - 6.8 mS/cm. The course of N-NO3- content was in inverse proportion to N-NH4+ content. Just the content of N-NH4+ was found as a critical parameter for vermicomposting of sewage sludge and its mixtures with garden biowaste. The optimal content of N-NH4+ in feedstock for surviving and living of earthworms should not exceed 200 ppm.
