T. Raunemaa, A. Hautojärvi, P. Jartti, J. Laurén, V. Lindfors, J. Räisänen. (1979). Trace element analysis of sound and decayed Norway spruce (Picea abies) by XRF and NAA methods. Silva Fennica vol. 13 no. 1 article id 5017. https://doi.org/10.14214/sf.a14871

Ashed tree samples from sound and decayed Norway spruce (Picea abies (L.) H. Karst.) were studied by means of fast neutron activation analysis, and for comparison, also by X-ray fluorescence analysis. In fast neutron activation analysis, the following elements were detected: (Na), Mg, Al, Si, K, Ca, Mn, Rb, Sr and Ba, and according to the results of the X-ray fluorescence method the elements present in the wood samples were: K, Ca, Mn, Rb, Sr and Ba. A general diminishing was revealed by both methods in most elemental concentrations studied, with exception of K and Rb, when going from a sound tree to a decayed one. The use of the ratio of the amounts of potassium to calcium as an indication of the degree of decay is therefore proposed.
