Table 4 Amounts of C, N, P, S, Ca, K, Mg, Mn and Lignin (% Initial amount), mean ± standard deviation (SD) in log segments of Fagus sylvatica, Picea abies and Pinus sylvestris; mass loss at 8 years: 32%, 24.9% and 24.6%, 18 years: 60.2%, 41.9% and 42.9%, and 36 years: 63.8% and 53.6% for beech, spruce and pine respectively; small values indicate significant difference (p < 0.05) between species as well as between periods of decomposition. n = number of samples

From: Nutrient retention and release in coarse woody debris of three important central European tree species and the use of NIRS to determine deadwood chemical properties
