The carbon, nitrogen, and phosphorus budget of the Åheden long-term nitrogen deposition experiment
This project made a comprehensive inventory of element stocks of carbon, nitrogen, and phosphorus in the organic layer, 0-10 and 10-20 cm into the mineral soil in 2017, after 13 years of annual N addition rates at 3, 6, 12, and 50 kg N ha-1 yr-1 (n=&). 10 cores were collected in each plot and subsamples analysed by IRMS and spectrophotometry.
Effects of whole-tree thinnings, nitrogen fertilisation and wood-ash applications on carbon and nitrogen stocks in biomass and soils of a Scots pine stand in northern Sweden
PI: Hyungwoo Lim
During thinning operation, uses of harvest-residues in producing renewable energy can mitigate CO2 emission via substitute effect for fossil fuel. 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.
