Description

Remains of ground and unground spruce needles and shoot axles taken at seven occasions (T1-T7) in the nutrient optimisation experiment 1477 Flakaliden in year 1988. T stands for occasion/tillfälle in Swedish. Primarily, the samples consist of needles and branch axles from branch whorl 4, 7, and 10. A key list of sample number is available for download.

Background information

The sampling includes three treatments: control (C), solid fertilisation (F) and irrigation with liquid fertiliser (IL). A total of 30 trees were sampled, 10 trees per treatment except for sampling T1 when 21 trees were sampled due to 130 cm heavy snow. Whole spruce branches were sampled. Branches were processed at Jädraås Experimental Forest, where they were separated in age classes for both needles and branch axles, dried at 85° in 48 h and weighed separately for each age class. Sampling dates: T1: 1988-05-03 T2: 1988-06-02 T3: 1988-06-14 T4: 1988-07-05 T5: 1988-07-19 T6: 1988-08-16 T7: 1988-09-20
