Abstract:
... Promoting humus production by composting is meaningful for decreasing organic wastes pollution, and repairing contaminated environment. However, the interaction of multiple humus formation pathways has limited to understand how to improve humus formation by composting. Here, humus formation has been divided into biotic and abiotic pathways to quantify their synergy to humus formation. Monomolecula ...
