Abstract
Decomposition of wood and fine root litter is much less studied than that of foliar litter. This chapter gives a brief overview to a few representative studies, giving some method approaches. For logs, there are decomposition classes given, which allow a description of the process. Accumulated mass loss may be determined by water displacement as decomposition produces more space. Further, wood chips as a model substrate may be placed in litter bags. In contrast to foliar litter, wood-decomposition rate may increase with time and be highest after 2–3 years, after which the rate may decrease. Root litter decomposition may be studied using litter bags, through following remaining root mass in soil cores or by direct observation. Root decomposition in climatic gradients has been related to mean annual temperature (MAT) and at a global level using several species also to calcium (Ca) concentration. Recent studies have allowed estimation of limit values for root litter decomposition.
