Total Calcium in Forest Soils of Maine and West Virginia.

The areal stocks and pedon distributions of total Ca (TCa) are examined and contrasted for representatives of extensively mapped forest soil series. For very deep series from Maine (ME) and West Virginia (WV), TCa stocks average 45184 kg ha^-1 and 10,848 kg ha^-1, respectively. For moderately deep or shallow series in ME and WV, TCa stocks average 12,634 kg ha^-1 and 2995 kg ha^-1, respectively. Within-pedon distributions of TCa reflect mineral reservoirs increasing with depth in ME, and dramatically declining in most series examined from WV. Variations in TCal stocks are lower among and within ME series than for those in WV, while variation in pedon TCa correlation to depth decreases as overall fertility increases. Relationships and implications to fertility and forest ecology and management are discussed for these series.
