Description
Spruce needle samples taken on three occasions in year 2009 in the soil warming experiment at Flakaliden. The samples consist of C+1-needles, taken on the seventh branch whorl. Occasion T1: 2009-05-13 running sample no. 1-50 Occasion T2: 2009-06-17 running sample no. 50-100 Occasion T3: 2009-10-29 running sample no. 100-150 Occasion T3: The samples are remains of pooled analysed samples consisting needles from five trees per plot. A key list of sample numbers is available for download.
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.
