What is the difference between human-made and natural compost?

Answer 1

Agent and timing are the differences between human-made and natural composts. Human-made composts derive from the consumption and excretion of carbon- and nitrogen-rich recyclables by macro- and micro-organisms, with the support of air, moisture and temperature. Natural composts represent the weathering of rocks and stones by water, wildlife and wind to produce the same dark-colored, fresh-smelling, nutrient-rich organic matter called humus under Mother Nature's guidance (versus compost through human involvement).
