Effects of the Manure Type on the Evolution of Its Co-Composting With Plant Residues and on the Agronomic Quality of the Compost Obtained

Urban Farm DB summary

A study on Gran Canaria, Spain co-composted municipal and agricultural plant residues with three manure types — chicken, goat and cow — in an open dynamic windrow system of three trapezoidal piles (1.5 m high, 2.5 m wide, 16 m long), mixed at 37.6% straw, 32.7% manure and 29.7% pruning residue by fresh weight. Temperature, humidity and physico-chemical parameters were tracked through the process. All three piles reached the sanitation threshold required by regulation (≥60°C for at least 7 days) and produced compost suitable for agricultural use.
