Abstract [en]

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

collected from.

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.
