7. THE INCREMENT BORER
Hollow auger bit (Ø 5 mm)
Measuring bulk density
2 measurements per plank
Dry weight/wet volume
8. THE INCREMENT BORER: Results
The measured wood densities are between 100 and 500 kg/m³
No density gradients
Density of planks and frames versus depth in wood
Jensen et al. (2011), p 12
10. ASH CONTENT: Results
Sulfur (S)Iron (Fe)
Higher percentage in planks (3-18%) than frames (2-6%)Calcium (Ca)
Jensen et al. (2011), p 14
Ash content as a function of depth in the wood
