Availability and Plant Uptake of Biosolid-Borne Metals

Table 4

Metal uptake rates (means where 𝑛=4) by shoots of three wheat cultivars grown on sand media amended with biosolids^†.

†The differences of metal uptake rate among the wheat cultivars were tested by one-way ANOVA. In each column of each growth time for cultivars, values followed by same upper case letter were not significantly different at 𝑃<0.05. The differences of the metal uptake rates among the metals in same cultivars were tested by one-way ANOVA. In each row, time, and cultivar, values followed by different lowercase letter were significantly different at 𝑃<0.05.
