WebExtractable Cd in soil of Ri·Cd treatment was significantly lower (P < 0.05) than that of UI·Cd (Fig. 3c). As a consequence, the amount of Cd content accumulated in root of treatment Ri·Cd was the lowest, compared with UI·Cd and Fm·Cd (Fig. 4). The treatment Ri·Cd with lower extractable Cd in soil (Fig. 3c) has lower Cd content in root (Fig WebTree mortality and soil moisture data at CAX and TAP were combined and analysed to examine hypothesis (a). Soil moisture availability was expressed as relative extractable water (REW) over the top 3 m of soil. REW is defined as the fraction of the maximum extractable water content (plant available water, PAW max) for each soil layer.
