Productivity of ecosystems depends to a large extent on the quantity of available nutrients. In natural ecosystems, much of the nutrient stock is unavailable because it is bound in live and dead organic matter. Additions to the pool of available nutrients come from several sources, but the largest and most important one is dead organic matter. Therefore, the productivity of ecosystems is often said to be related to the rate of nutrient release from, or the mineralization of, organic litter (Ghilarov 1971, Satchell 1974).
