Regrading the depth of a calcic horizon?

Question

How can a calcic horizon be found deeper in a region of lower rainfall than its depth in an area of higher rainfall?

Answer 1

A simple answer is merely erosion.

Under the same ground cover and slope situations, increasing rainfall automatically increase topsoil loss via erosion.  While it would make more sense for the calcic horizon to be directly related to precipitation, the inverse is often true.  I have found topsoil loss to be an important issue in relating calcic horizon depth to rainfall.

Answer 2

There is more than just rain that contributes to differences in soils and depth with regard to any specific. Temperature, climate, slope (as was mentioned), location, and types of vegetation all play parts in how soils develop and to what depth they are or how fast that accumulates. Also, the movement of material by water into the soil will obviously be faster and deeper with greater rains and various soil conditions/ types.

Answer 3

Calcium is water soluable.Less rainfall washs it down(lower water tables.More rainfall floods it up.
