Climate benefit from the afforestation of available agricultural land

PI: Reimo Lutter

According to the recent estimation for Northern Europe, about 1.8-2.6 M ha of agricultural land is available for afforestation and intensive biomass production (Rytter et al. 2016). However, the long-term effects of different species C sequestration potential are unknown on former agricultural land. For the basis of current project, the growth data was obtained from tree species (hybrid aspen, poplar, birch, spruce, larch and willow) experiments on five former agricultural sites along a latitudinal gradient in Sweden (56° to 64°N). Site index curves were calculated to predict the potential production for each tree species and different long-term scenarios were tested to investigate each species climate benefit potential on former agricultural lands. More detailed information about the experiment: Rytter, L. and Lundmark, T. 2010 Trädslagsförsök med inriktning på biomassaproduktion [Tree species trial with emphasis on biomass production].

Comparison of ecosystem C and N stocks in Norway spruce vs. Scots pine stands throughout Sweden

PI: Robert Blasko

We are evaluating the performance of Norway spruce vs. Scots pine stands at the sites equally suitable for both species in the experiments at Kulbäcksliden 1028-1029, Flakaträsk 2458, Övra 1061, and Björkheden 1062. The aim is to evaluate how the different species productivity affects C and N stocks of he ecosystem and some of the important C fluxes; soil CO2 efflux and litterfall.

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.
