A Note on The Influence of Soil Parent Material on Northern Red OAK Specific Gravity

Soil parent material was found to affect the specific gravity of northern red oak wood ( Quercus rubra L. ). The unextracted specific gravity of wood grown on limestone soils was 0.597 and that of wood grown on sandstone soils was 0.581. Site quality within a soil type had no significant effect. The relationship was independent of both rate of growth and latewood percentage.
