Figure 9. Cumulative base cation uptake of Wytana saltbush, Big saltbush, and Maritime barley grown in columns with water table positions at 114, 76, and 38 cm below the sand surface. Columns planted to the same species and identified by the same letter are not significantly different at alpha = 0.05. Differences in base cation uptake were significant among all species at p=0.10.
