Soil scarification means lot to the regeneration of the forest
because a good soil scarification boost the increment of the plants
and it also makes the plants less attractive to dangerous insects.
The surveys purpose was to investigate how different site factors
influence the soil scarifications results. The goal was to see if any
scarification method was better adapted to a certain site then the
other. In order to see a result the survey investigated the bearing
capacity of the stands, the surface structure and the slope of the
The surveys material has been collected during august - October
2013 on SCA: s forest in Ångermanland in Sweden. Totally has
65 harrowed sites and 35 scalped sites been visited and material
The survey result shows that the scarification quality after
scalping was higher than after harrowed sites. The number of 5: s
and 4: s was more frequent after scalping but the number of
mineral 3: s was higher after harrowing. The analysis of the
results shows that scalping was more sensitive to the site slope
and surface structure then harrowed sites, but when used on the
the right ground it will provide a better quality result.
The conclusion of the survey was that harrowing is the better
choice of the scarification methods because it showed a more
stable result then scalping that is more depending on the terrain
conditions. Harrowing should not be used on moist ground due to
the risk of Hylobius abietis attacking the plants. Scalping on the
other hand showed a better result of the scarification quality and
on the right ground it is the optimal choice.
