Abstract

A study was started aiming at assessing the pedogenic potential of zeolitized tuffs as possible substrates to soil formation, especially for soil rebuilding in degraded lands. This paper deals with Ca, Al, Mg and Fe distribution in leachates obtained by a sequence of experimental weathering cycles of Campanian Ignimbrite (yellow facies) by water (W) and Na-humate (Na-Hu). The cation amounts were Al>Ca>Mg>Fe in W and Ca>Al>Mg>Fe in Na-Hu extracts, the latter being more efficient. © 2008 Elsevier B.V. All rights reserved.
