Process of redeposition of secondary calcium carbonate from other parts of the soil profile which, if sufficiently concentrated, may develop into a calcrete, caliche, kunkar, or calcic horizon (all similar and usually comprising more than 15% by weight of calcium carbonate in more than 150mm soil thickness). Calcification involves limited upward and lateral movement of calcium salts in solution, and downward movement in less-wet periods. When occasionally leaching is deeper, some but not all of it may redissolve.
