Effects of whole-tree thinnings, nitrogen fertilisation and wood-ash application on carbon and nitrogen stocks and soil chemistry in a Scots pine stand in northern Sweden. During thinning operation, harvesting residues can be utilized for renewable energy feedstocks. However, removals of the residues can also degrade biomass productivity and cause soil acidification. Combination of four treatments (conventional thinning, whole-tree thinning, with a compensatory fertilization, and with repeated fertilization), with split-plot based ash addition, we investigate biomass and soil carbon stocks in response to removals of harvest-residues.
