Degerfors - Establishment of a new stand managed with precisely added nutrient load

PI: Fredrik Sjödin

Summary This trial aims to monitor effects of a specific and precisely added nutritive load in the establishment of a new generation plantlings. The trial also aims to repeat the same load yearly after establishment to see growth effects. The trial is set up as parcels of pine, spruce and birch both in mixtures and monoculture. Nutrition management, growth and survival of common species in monocultures and in mixed stands. Established 2020-06

7201 Gap trial Kälmyrbränna

PI: Fredrik Sjödin

The aim of this experiment is to study establishment, survival and growth of Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) planted in gaps ofpine dominated forest. Further, the study will also show how the gaps affect the stand increment compared to a stand without gaps. The theory is that the gaps increase incoming light and therefore also the increment.

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.
