PI: Ulla Nylander
Data from 1470 Rödålund (biomass sampling, plants inventory, ash content).
[ID: 108] 1470 Rödålund
PI: Hyungwoo Lim
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.
[ID: 106] Impacts of tree species identity and mixing on ecosystem C and N stocks
PI: Robert Blasko
The original aim of this experiment was to compare the growth of Scots pine vs. Norway spruce, and their mixture at a medium fertility site near Främlingshem suitable for the growth of both species. Our aim was to evaluate the effects of tree species and their mixing on ecosystem C and N stocks, as well as on some of the important C fluxes.

[ID: 103] Interactive effects on forest carbon cycling between nitrogen fertilization and precipitation
PI: Hyungwoo Lim
We are investigating the interactive effect between fertilization and water availability on biomass production, and examining factors constraining efficiencies with which assimilated carbon partitions into wood biomass.

[ID: 102] Long-term nutrient optimization for ecosystem carbon sequestration potential
PI: Hyungwoo Lim
We determine carbon accumulation in response to 35-years tree nutrition optimization. Tree nutrition has been administrated based on annual foliar nutrient detection and corresponding fertilization treatment. Aboveground carbon accumulation is determined by standing biomass and belowground carbon accumulation is determined by both soil carbon stock and root biomass. Based on litterfall production and consecutive measurements on tree dimensions, annual net primary production is estimated.
