    • Abstract
  • Enzyme activities in compost containing various proportions of sludge and tea waste were compared.The results showed that the higher compost temperature was reached on the third day,and maintained for 16-18 days for all treatments.The total N in the compost containing 40%-50% of sludge was higher than when 30% sludge was used.The total N of Treatment D was 19.17 gg-1,which was the highest among all treatments.The order of total N content for the treatments was DECBA.The available N of Treatment E was 1171 mgg-1,which was the highest among all treatments.The order of average available N for the treatments was EDCBA.The cellulase activity increased linearly as the temperature rose.On the 8th day,the cellulase activities of the Treatment A,B,C and E reached maximum values of 0.396,0.498,0.499 and 0.498 mg-1-1,respectively.Treatment E attained the highest value of 0.590 mg-1-1 on 12th day.The urease activity decreased with increasing tea waste addition.The order of the average urease activity in the treatments was CADEB.
