Table 1.

The concentrations of REEs, Ca, Mg, Fe, and al in the soil solution with Ce and Y treatments in the high clay and low clay soils at plant harvest. Values represent the mean ± standard deviation (n = 4). Columns followed by different letters are significantly different at 5% level according to the least significant difference post hoc test.
