Description
Remains of ground C+1 spruce needles samples collected 2007-11-27 in the soil warming experiment at Flakaliden. Nutrient analysis was performed at Lunds University.
Background information
The soil warming experiment, which started in 1994 and ended in the autumn of 2012, was conducted on two treatments: irrigation with water (I) and irrigation with liquid fertiliser (IL), with two control plots and two heated plots on each treatment, a total of eight plots (size 10x10 m). The ground was heated by heating cables installed between humus and mineral soil. Heated plots were kept 5°C warmer than the control areas during the vegetation period. Soil warming started one month before normal spring thaw. In the autumn, when the control areas froze, the heating was reduced by 1°C per week, which means that the frost-free period was extended around two months per year.
