Since the publication of the 2 nd edition, there have been substantial developments in the field of litter decomposition. This fully revised and updated 3 rd edition of Plant Litter reflects and discusses new findings and re-evaluates earlier ones in light of recent research and with regard to current areas of investigation.

The availability of several long-term studies allows a more in-depth approach to decomposition patterns and to the later stages of decomposition, as well as to humus formation and accumulation.

The latest information focuses on three fields:

- the effects of manganese on decomposition and possibly on carbon sequestration,

- new findings on decomposition dynamics, and

- the new analytical technique using 13 C-NMR.

Introduction.- Decomposition as a process - some main features.- Decomposer organisms.- Initial litter chemical composition.- Changes in substrate composition during decomposition.- Chemical constituents as rate regulating: initial variation and changes during decomposition. New and traditional analytical techniques.- Climatic environment.- Decomposition of fine root and woody litter.- Models that describe litter decomposition.- Some possible influences on decomposition pattern, regression model, stable fraction and C sequestration.- Does humus accumulate and where? What factors may influence? Estimating carbon sequestration rates on a regional scale.
