pH and preventing drift is, therefore, an important aspect of nutrient management. Plants affect root zone pH primarily through differential uptake of cation and anion nutrients ( Haynes, 1990 ; Lea-Cox et al., 1996 ; Marschner, 2012 ; Rengel, 2003

Bayesian clustering of five individual plants per taxa without a priori assignment of individuals to hierarchical groups was used to determine genetic structure and test for possible admixture between taxa, which might otherwise confound phylogenetic
