Charcoal is a naturally occurring form of carbon. Charcoal is a byproduct of burned ecosystems such as forests and prairies that captures the carbon in plant matter and preserves it in a form that can stay in the soil for between several hundred and 10,000 years. Known as recalcitrant carbon, charcoal captures organic matter in its pores, creating areas of “concentrated labile carbon,” which is the most accessible form of carbon for the microbial community. In addition, charcoal can capture nutrients and water, supplying a broad array of fertility needs for plants. Biochar is what charcoal is called when used for agricultural purposes.
