표고(Lentinula edodes), 노루궁뎅이(Hericium erinaceus), 느타리(Pleurotus ostreatus)의 버섯수확후배지(spent mushroom substrate, SMS)를 퇴비화에 활용하였다. 퇴비화 온도변화는 50oC 이상에서 7일에서 10일 동안 지속 되어 30일에 부숙이 완료되었다. 퇴비화 된 LeCSMS, HeCSMS는 130%, 80% 무종자에 대한 종자 발아지수를 보여 부숙도에 대한 종자 발아지수를 충족하였다. 퇴비화에 따른 물리 화학적 변화를 조사한 바 pH 범위가 4-5 에서 6-7로 증가 되었고 EC는 1-1.4 dS/m로 소폭 감소 되었으며 유기질 함량은 LeCSMS에서 36.9%로 SMS에 비하여 60% 이상 가장 큰 폭으로 감소 되었다. LeCSMS 를 기준으로 N (1.2%), P(2.3%), K(0.77%)함량이 조사되었으며 중금속은 모든 CSMS에서 기준치 이하였으며 Ca, Mg는 30%에서 60%이상 증가하였다. C/N비는 LeCSMS, HeCSMS에서 15% 낮았으나 PoCSMS에서 32%로 높게 나타났다. LeCSMS 처리에 따른 고추 유묘 생육효과는 시판 유기퇴비 처리구 등 대조 구에 비하여 초장이 60% 이상 높게 성장했으며 옆폭, 옆장, 옆수에서 다른 대조 구 에 비하여 모두 우수한 생육 효과를 보였다.

This study aimed to assess the feasibility of composting spent mushroom substrate (SMS) materials of Lentinula edodes (Le), Hericium erinaceus (He), and Pleurotus ostreatus (Po). The different SMSs were composted for 7 to 10 days at high temperatures over 50oC; the composting procedure was completed in 30 days. A maturity test was conducted using the radish seed germination index and CoMMe-100. The composted SMS (CSMS) from Le and He showed gemination indices of 130% and 81%, respectively, that satisfied the criteria of maturity standard (gemination index over 70%) and the CoMMe-100 analysis. The physicochemical changes of CSMSs included an increase in the pH range from 4–5 to 6–7, slight reduction in the EC to 1–1.4 dS/m, and an organic content of 36.9% in LeCSMS. In LeCSMS, the contents of N, P, and K were 1.2%, 2.3%, and 0.77%, respectively, and heavy metals were detected below the standard value in all CSMSs; the Ca and Mg contents in the CSMSs were increased from 30% to 60% when compared to those in the SMSs. The C/N ratio (from 26–33) in LeSMS and HeSMS decreased to 15.3–15.9 in CSMSs. The growth effect of LeCSMS treatment on pepper seedlings was 60% higher than that in the control groups , one of which was treated with commercial organic compost; the former showed a superior growth effect on the leaf width, leaf length, and leaf number compared to other control groups. In conclusion, LeCSMS and HeCSMS could be utilized as compost resources capable of efficient soil amendment and plant growth promotion.
