The main causes of soil acidity include (i) organic matter decay which produces hydrogen ions (H+ ), (ii) crop absorption of lime- like elements such as mono and bivalent cations (K+ , Ca2+ , Mg2+ ), and (iii) the use of ammoniacal fertilizers; all these processes havea strong and direct impact on soil acidity (e.g. pH) (Martens, 2001; Tang and Rengel, 2003)
