Relative extractable soil water

WebCrop water use, also known as evapotranspiration (ET), represents soil evaporation and the water used by a crop for growth and cooling purposes. This water is extracted from the soil root zone by the root system, which represents transpiration and is no longer available as stored water in the soil. Consequently, ET is used interchangeably with crop water use.

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.
