Description
Ground spruce needles from a decomposition study in the soil warming experiment 10510 Flakaliden. Needles were incubated in November 1997 and then collected on five occasions: • 1998-06-04 • 1998-10-05 • 1999-05-29 • 1999-09-28 • 2000-10-10
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.
