Slash
Forest residue (linguistically inaccurate and blow room ) referred to in the forestry after harvesting (logging or slash ) on the clubface remaining tree residues and biomass residues which are left or cleared and used in the forest. The residual wood contained in the logging waste is referred to as residual forest wood .
Logging waste and forest residues are often fäschlicherweise equated.
composition
The logging waste consists of Stock timber ( Baumstüpfe ), non-solid wood ( rice wood ) and tops and foliage (leaves, needles), cones , bark residues , X-timber (not usable compact wood and inferior stem parts, stock lazy butt logs and are transmitted felled trees) and impact waste.
The logging waste corresponds to 5–10 % of the total yield for softwood and 12–15% for hardwood .
use
Chemically, wood mainly consists of carbon , oxygen and hydrogen , which, thanks to their high availability, are of little importance as plant nutrients . The main part of the rarer nutrients available in the area, on the other hand, is stored in leaves and needles , which should definitely remain on the area to avoid excessive nutrient discharge from the forest. Therefore, the so-called full and whole tree use , which also uses these remains, is viewed very critically from an ecological point of view.
