How do I recognize finished compost?

Anyone who composts knows the key question: When is the compost really ready? Because only when it has reached the right stage of maturity does it reach its full potential as a natural fertilizer and soil conditioner. Many people are unsure how to clearly tell when compost is mature and when it can be safely used in the garden. But there are clear signs and stages of maturity that reliably show you how far along your compost is—and what it’s best used for.
