Gyeonggi Province is a major oyster mushroom production region, and most of the mushrooms are cultivated in bottle. Most oyster mushrooms are produced year-round using a bottle cultivation system, so a stable supply of substrate materials plays a significant role in farm management. Therefore, we aim to analyze the farm culture substrate and raw material components to use the information for a stable substrate supply. In June 2024, substrate production, sterilization conditions and bottle size were investigated for 20 farms status. In September 2025, 16 raw materials and 15 mixed substrates were analyzed for physicochemical properties and particle size distribution. The daily production of substrate was found to range from 4,000 to 11,000 bottles, and bottles with a volume of 1,100 ml and an opening diameter of 70 to 75 mm were used. The mixed substrate had a pH of 4.7~6.0, a moisture content of 65~74%, and a total nitrogen content 1.3~2.0%. The sawdust particle size distribution varied by company, with the 1.0~2.0 mm size accounting for the majority. To address the unstable prices and supply of substrate materials, continuous monitoring of raw materials and farm substrate current situation is necessary.
