organic matter is 2.73 and 0.53% for the two horizons, A and C, respectively, Sandy loam
textured throughout the profile. It is classified (WRB) as Eutric Regosol.
The soil developed on volcanic material in Greece seems to show quite different properties
from the other volcanic soil due to climatic conditions prevailing in these regions.
