What is Compost
It is defined as "stably decomposed organic matter." In other words, compost is the "brown fluffy stuff" you find in healthy soil that provides plants with essential nutrients. Compost is produced when formerly living things go through the process of aerobic decomposition. This process driven by oxygen-breathing bacteria and fungi.
