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 ¹³C-NMR.
