Effects of microbial agents on NH3 emission during pig manure composting
|
Abstract:
This paper studied the effects of different mixed microbial agents on the NH3 emission during pig manure-sawdust (9:1, fresh w/w) composting. The results showed that the NH3 emission was mainly occurred at the high temperature (>50 degrees C) period during the early 15 days of composting. The addition of 3 per thousand mixed microbial agents 1, 2 and 3 had a definite inhibitory effect on the NH3 emission, and the effect of 5 per thousand mixed microbial agent 1 was significant (P < 0.05).
