Treatments | Composition | Mesophilic and thermophilic ratio |
T1 | All nitrogen-rich substrate (40 kg of goat dung and 20 kg of pig dung) applied at the start of composting (mesophilic stage). | 1:0 |
T2 | All nitrogen-rich substrate applied at thermophilic stage (>50˚C) after the start of composting | 0:1 |
T3 | 50 % of nitrogen-rich substrate (20 kg of goat dung and 10 kg of pig dung) applied at the start of composting and the remaining 50% added at thermophilic stage. | 1:1 |
T4 | 20% of nitrogen-rich substrate (8 kg of goat dung and 4 kg of pig dung) applied at the start of composting and the remaining 80% (32 kg of goat dung and 16 kg of pig dung) added at the thermophilic stage. | 0.2:0.8 |
T5 | 80% of nitrogen-rich substrate applied at the start of composting and the remaining 20% added at the thermophilic stage. | 0.8:0.2 |
