Abstract

The counts ofAzotobacter, N-fixing clostridia, aerobic cellulose decomposing bacteria, spore formers and actinomycetes were not affected by examined irradiation doses. There were, however, indications of a disturbance in the balance between organisms as evidenced by the rapid increase of actinomycetes and sporeformers during incubation. The effects of various irradiation doses on organic matter decomposition, N-fixing capacity and nitrification power were negligible.
