      다국어 초록 (Multilingual Abstract)

      To examine the agricultural availability of paper sludge, this study investigated the degradation rate of sludge, CO₂ generation out of soil treated with sludge and the degration characteristics of sludge in soil
      1. Degradation rate of paper in soil at weeks after treatment was 19.0% at natural temperature and 28.0% at incubation temperature(30℃)
      2. The changes of T-C, T-N and C/N ratio of paper sludge in soil at 12 weeks after treatment were 15.5%, 0.22% and 71, respectively, at natural temperature, and 14.5%, 0.24% and 60, respectively at incubation temperature.
      3. The changes of pH in soil treated with paper were 6.7∼7.4 at natural temperature and 6.1∼8.0 at incubation temperature.
      4. CO₂ generations in soil treated with 1.0%, 3.0% and 5.0% of paper sludge at 12weeks after treatment were 247mg/100g, 334mg/100g and 458mg/100g, respectively, at natural temperature and 385mg/100g, 550mg/100g and 618mg/100g, respectively, at incubation temperature(30℃)
