Most of us appreciate and expect compost to be mature. We assess maturity using a stability test. Our compost may be stable but not mature! Forced air compost systems in particular, allow us to stabilize the compost by drying it, but it may not be mature. Dry immature compost may heat and create odor when its rewetted. It also may contain high fecal coliform that survive the high temperatures early in the process. Immature but stable compost may be fine for some applications, but not for all. It would be good to know!
