The albic horizon is poor in organic carbon (2.7 mg [m.sup.-2] [yr.sup.-1] [cm.sup.-1]), because the chelates formed there are translocated into the spodic horizon.
Due to the large proportion of Ca-fulvates, humus is Ca-fulvic in the albic horizon as well as in the yellow area of the spodic horizon.
About a twofold increase in the content of fine sand and a more than 120-fold increase in very fine sand have taken place in the albic horizon, while silt and clay have accumulated in particularly large quantities in the brown area of the spodic horizon.
Although an accumulation of sand was found not only in the albic horizon, but also in the mellowed yellow area of the spodic horizon, an equal balance of the sand fraction has been formed in the entire profile.
Only the albic horizon is almost free from pigments.
Microcline accounts for only some per cent of feldspars, which is a little more preserved in the albic horizon and has disappeared from the spodic horizon.
The largest increase in the heavy mineral suite in the very fine sand of the albic horizon appears to be caused by the peak weathering and acid hydrolysis of the coarser fractions therein.
