본 연구는 한약탕제 찌꺼기를 친환경 퇴비자원으로서 재활용하기 위하여 발효과정을 거친 퇴비(MHWC; medicinal herb waste compost)와 계분퇴비(PMC; poultry manure compost) 및 이들을 혼합한 퇴비(MHWC+PMC, 1:1)를 식재 2년생 복분자 포장에 무처리(UC; untreated control, 0), 20, 40 Mg/ha로 각각 처리하였다. 밭 토양의 화학성과 수확한 복분자 과실의 수량 및 당도변화 조사 결과는 다음과 같다. 토양 pH는 UC보다 모두 증가하여 유의적인 pH 변화 조절기능이 인정되었다. EC는 MHWC 처리구가 UC보다 0.56-0.46 배 감소를 보였으며, PMC 처리구와 차이가 있었다. 유기물 함량과 질소함량은 퇴비 종류와 무관하게 증가하였고, 가장 증가된 퇴비는 MHWC이었다. 유효인산함량은 퇴비 종류 및 처리량에 따른 차이가 있었다. 각 퇴비를 처리한 토양의 중금속 함량은 토양오염우려기준보다 낮았다. MHWC 처리구의 수량과 당도는 다른 처리구에 비해 높은 경향을 나타내었다. 이상의 결과로 보아, MHWC 처리는 복분자 경작지의 토양환경개선과 더불어 복분자 과실의 수량 및 당도를 향상시키는 효과적인 퇴비자원인 것으로 사료된다.
In order to reuse remnants of medicinal herb extracts as an environment-friendly manure, fermented compost made from medicinal herb waste (MHWC), poultry manure compost (PMC) and MHWC+PMC (1:1, w/w) were applied on upland soil cultivated with 2 year-old Bokbunja plants. The results of the changes of soil chemical properties on upland soil, the yield and the sugar contents of the fruit harvested were summarized as follows. The pH in soils treated with composts (STCs) was significantly changed (p<0.05) compared with untreated control (UC) group. The electrical conductivity (EC) in MHWC group was decreased 0.46-0.56 times compared with UC, and it was different from PMC groups. The contents of organic matter and total nitrogen were increased in all of the treatments and MHWC group was the highest among the all groups. The content of available phosphorous was different by types and amounts of the composts. The content of heavy metal in all groups did not exceed the standard content for soil contamination. The yield and the sugar contents of the fruit harvested were the highest in the treatments of MHWC. In conclusion, MHWC is an effective compost resource on improvement of soil environment and promoting the fruit qualities.
