The Composting Process Biological decomposition in aerobic environment Decomposition & mineralization by microbes • Bacteria, actinomycetes, fungi, protozoans, nematodes • Food source – Nitrogen (biodegradable organic matter) • Energy source – Carbon (bulking agent) Outputs • Heat • Water Vapor • Carbon Dioxide • Nutrients and minerals (compost) Process occurs naturally, but can be accelerated by controlling essential elements
