During Phase I, on days 4 and 5 for the first and second trial respectively, the composter was opened (first turn) and its content manually mixed with forks, and moistened (to restore humidity lost) with the other half of the nitrogen supplements dissolved in the water. Two more turns were carried out, on days 7 and 9, and at days 11 and 13, for the first and second trial respectively (water was added if needed). Afterwards, the pasteurization and conditioning (Phase II) was initiated. During this phase, the temperature was slowly increased (5 C/h) until 55 Ce58 C was reached. This temperature was maintained for 48 h; then, it was lowered to 45 Ce50 C and kept until an ammonia scent was no longer perceptible. Phase II lasted 16 days in both trials.
