Abstract
This study was performed to compare medium characteristics during the composting stage for medium turning performed using an excavator agitator and a prototype medium turner in button mushroom cultivation. The changes in temperature in the medium did not significantly differ between the treatments until the 3rd turn performed using the excavator agitator. However, during the 4th and 5th turns, the temperature increased during turning with the prototype medium turner. During outdoor composting, various types of microorganisms such as thermophilic bacteria (Bacillus spp.), Actinomycetes, fluorescent Pseudomonas spp., and filamentous fungi were found to be distributed in the medium. The counts of aerobic bacteria and fluorescent Pseudomonas spp. did not significantly differ between treatments, and the counts of thermophilic bacteria and thermophilic actinomycetes were slightly higher during turning with the prototype medium turner. The rice straw was slightly shorter and water content lower for the prototype medium turner. There was no significant difference between pH and EC treatments. The L, a, and b values tended to increase on turning with the prototype medium turner.
