DETRITUS CONTENT IN WOODY PLANTS

In the conventional sense, woody detritus contains woody remains, which usually retain some parts of the tree form and consist of snags, logs, stumps, dry branches of living trees, dead roots, as well as remains buried in the soil stratum. This is an ecologically important component of the forest stand, influencing the biodiversity of species in the forest ecosystem. However, there is an exergetic view of the concept of detritus as a kind of reference level in calculating ecosystem exergy. The exergy reflects the degree of development or complexity of the ecosystem centered on the exergy weighting factor. In this case, the energy content of detritus is important. Traditionally, for organic matter, it is assumed to be 18.7 kJ/g. In the presented work, an attempt has made to obtain the energy content of detritus based on the calorific value of wood. Using the example of a pine stand, it has shown that specific exergy can be obtained by the way that is alternative to traditional methods, where the exergy weighting factor is calculated based on the information content of the genome expressed during the life cycle of the organism.
