Plant Litter

The revised and updated 3rd edition of Plant Litter reflects and discusses new findings and re-evaluates earlier ones in light of recent research and current areas of investigation. Covers decomposition dynamics and new analytical technique using 13c-nmr.

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.

Third edition, fully revised and updated with much new material New information emphasizes on three fields: the effects of manganese on decomposition and possibly on carbon sequestration, new results on decomposition dynamics, and the new analytical technique using 13C-NMR In-depth approach to the results of long-term studies Includes supplementary material: sn.pub/extras

Since the publication of the 2nd edition, there have been substantial developments in the field of litter decomposition. This fully revised and updated 3rd 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:

(i) the effects of manganese on decomposition and possibly on carbon sequestration,

(ii) new findings on decomposition dynamics, and

(iii) the new analytical technique using 13C-NMR.
