Description

Remains of spruce needle samples taken 2013-10-30 in the nutrient optimisation experiment 1477 Flakaliden. The samples are pooled samples consisting of C+1-needles from five trees on each parcel. Needle samples were taken from the upper third of the tree crown, with the intention of sampling the seventh branch whorl. Measurements of isotope ratios and mass fractions of C and N was performed at the Department of Forest Ecology and Management, SLU Umeå. A key list of sample numbers is available for download.

Background information

Starting from 2013, needle samples were only taken from the plots that constituted the basic experiment, i.e., the unthinned plots. The sampling includes four treatments: control (C), solid fertilisation (F), irrigation with liquid fertiliser (IL ) and previously irrigated parcels (I) that started to be irrigated with liquid fertiliser in 2007 (new IL). In total 13 parcels were sampled.
