Description :
The aim of this paper was to review and organize existing knowledge of the decomposition of Scots pine needle litter into a structure and create a system of factors influencing its decomposition from newly shed litter though to soil organic matter (SOM). The AA. suggest a simple regulating mechanism for its sequestration of carbon. Focus will be on foliar litter of Scots pine and the genus Pinus. A model for litter decomposition based on chemical changes during decomposition is presented. The climatic influences on decomposition in the early and late stages are discussed. The limit value concept is estimated. In conclusion, it appears that factors regulating the size of the stable litter fraction may be used as a tool on a larger geographical scale to predict carbon sequestration rates in pine forests.
