Abstract

The quality of the biological fertilizer was based on the population of inoculated microorganism. The important efforts made to increase the population and maintain the population of microorganisms during storage was using the best carrier. The aim of this study was to measure the population dynamics of some microbes due to the application of various types of earthworms in producing biofertilizer. The study was conducted in Biology and Biotechnology SoilLaboratory, Department of Agriculture, Universitas Sumatera Utara. The design used was a Factorial Randomized Block Design consisting of 2 factors. The first factor was a type of earthworm with 4 treatments viz; without earthworm, anecic earthworms, endogeicearthworms, and epigeic earthworms. The second factor was a type of microorganism inoculants with 6treatments, viz; Azotobacter sp., Azospirillum sp., Bacillussubtilis,Trichodermapinophilus, Talaromyces asperellum, and Syncephalastrum racemosum. The results showed that there was a significant interaction between the types of earthworms ininfluencing the population of each microorganisms in the medium. The highest alteration of microbial population were found in Azotobacter sp. and Trichodermaasperellum. The best type of earthworm that could beused on the inoculum medium was the epigeic earthworm.
