Dissemination

Back to the forest
Last but not least, we spread the ashes in the forest, in areas planned in cooperation with the Forestry Board. This cooperation ensures that it never spread ashes on sensitive land, or other nature that may be damaged.

The Forestry Board send us digital maps that we have in the machine's GPS. As the ashes spread, we draw it on the map so we can see what areas we have been at. In this way, the landowner easily can see where the ashes have been spread. Normal amount of spread is 3 tonnes of ash per hectare.


In anticipation of the spread of forest, ash need sometimes be stored. Intermediate storage of ashes or finished ash product should be done so that leaching is minimized. The storage location should be dry and remain relatively high in the terrain. Permanent middle layer should have hard-surface and access to water and wave.
The actual spread have to be done in such a way that damage to soils and vegetation is avoided. The ash should be spread out evenly. Ash recycling should (like nitrogen fertilization) not occur in or near sensitive areas.

 

Areas where ash recycling is not allowed
Ashes should not be spread over:

  • Lake and Streams
     

  • Wetlands with high natural and cultural values
     

  • Formally protected land
     

  • Key biotopes (Woodland key- habitat of rare and endangered species)
     

  • Personal property
     

  • Someone elses property  and road

An ash-free zone from these places is 25 meters, in addition to someone elses property and road, in which it shall be 10 meters.

  


 

Explanation
Although the purpose of the ashes is to improve the chemical state, ash which falls directly into the water can harm the environment. This is due primarily to the fact that aquatic organisms can be damaged by the ash initial salt effect. The ash also contains substances that may be harmful to aquatic organisms on the high dose ports directly in the aquatic environment.

In direct proximity to water its often high nature values. Therefore, an ash-free zone should be provided around all lakes and rivers.

An ash-free zone should also be given to wetlands with high nature, key biotopes and land. Ash recycling in connection to formally protected land, should also be  an ash-free zone provided.

Ashless zones shall also be given to someone elses property and roads. If these donīt have any special nature, it is sufficient, however, with a zone of 10 meters. Ash recycling can be done on fresh clearings where there are fields of vegetation which can take up the industry and prevent leaching, or the ash is so well tempered and dissolves so slowly that the extra leaching from hygget become insignificant.

In the nitrogen-rich soils should ash recycling done in such a way that it does not lead to increased nitrogen leaching. Studies shows that ash recycling do not cause an increase in nitrate leaching. But for safety's sake it is best to wait until there is established field vegetation on the final felled area,  which can take up any nitrogen released.
