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 1987. T stands for occasion/tillfälle in Swedish. Primarily, the samples consist of needles and branch axles from branch whorl 4, 7, and 10. Ground needles and ground branch axles (T1-T7) = sample no. Fla 748-870. Unground needles and branch axles (T1-T7) = sample no. 1-147. Key lists of samples numbers can be downloaded.

Background information

The sampling includes three treatments: control (C), solid fertilisation (F) and irrigation with liquid fertiliser (IL). Ten trees per treatment were sampled, a total of 30 trees at each occasion. Whole spruce branches were sampled. For carbohydrate analysis fresh needles were taken from each age class on the main axis of the 4th, 7th and 10th whorls. Sample branches were then frozen. The frozen 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: 1987-05-19 T2: 1987-06-02 T3: 1987-06-16 T4: 1987-06-30 T5: 1987-07-14 T6: 1987-08-11 T7: 1987-09-15
