이상의 결과를 종합하면, 평가대상 토양을 증류수로 20배 희석하여 200rpm 으로 30분간 진탕한 후 PDA (감자추출배지)와 혼합하여 121℃에서 20분간 살균한 후 Coriolus hirsutus (MKACC 50560) 균을 접종한다. 접종완료 후 25℃에서 5일간 배양한 후 균사 생장을 측정하여 담자균의 균사 생장률 (목적토양에서의 균사생장/PDA 에서의 균사생장×100)을 계산한다. 이 기준에 따라 균사생장률이 60%이상이 되면 대상 토양은 작물 생육에 적합한 토양이라고 추정할 수 있다. 이러한 방법은 토양의 건전성 평가를 위한 신속한 간이검사를 통하여 소량의 시료를 가지고 단기간 내 대량 분석을 가능하게 하여 토양 건정성 평가의 기초 자료로 사용될 수 있다고 사료된다.

Application of sludge wastes into the field may help soil fertility with physical, chemical and biological properties. Efficient use of sludge waste, however, requires an individual assessment of the waste products. A lot of experiment into the organic waste-treated soils has been done for decade. However, studies have not been carried out on the assessment of agricultural soil by Basidiomycota. This study was assessed the influence of sludge application on soil healthy in agricultural upland soils. The organic wastes selected for long-term application experiment in this study were municipal sewage sludge (MSS), industrial sewage sludge (ISS), leather processing sludge (LS), alcohol fermentation processing sludge (FS), and pig manure compost (PMC). To develop the soil healthy assesment method, soil samples were diluted by 20X with distilled water. After shaking at 200rpm for 30 minutes, the shaked sample was mixed on PDA(Potato Dextrose Agar). And sterilized at 121℃ for 20 minutes. Coriolus hirsutus (MKACC 50560) was inoculated on petri-dish including PDA mixed sample. After the media was incubated at 25℃ for five days, the mycelial growth of C. hirsutus was measured. When the mycelial growth on sample media was compared with growth on media contained PDA only, well grown media contained sample soil was assesed as healthy soil. The results suggest that the simple method by Coriolus hirsutus is a handy way to assess the healthy of waste sludge-applied upland soils.
