which it is the leaching of minerals

  • Leaching (agriculture)

    Leaching: Leaching,, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer. This transport results in a porous and open top layer and a dense,
