2. NH3, N2O and CH4 emissions during passively aerated composting of straw-rich pig manure.

Straw-rich manure from organic pig farming systems was composted in passively aerated static piles to estimate the effect of monthly turning on organic matter degradation and NH3, N2O and CH4 emissions. Turning enhanced the rate of drying and degradation. The four-month treatment degraded 57±3% of...
