The suitability of different extractants for estimating the plant availability of rare earth elements (REEs) in soils was assessed in a greenhouse study. 0.43 M CH3COOH, 0.01 M CaCl2, 0.1 M HCl, and DTPA were used as extractants and winter wheat (Triticum aestivum L.) as a test crop. Soil samples with diverse chemical and physical properties were collected from 9 different rural regions of China. REEs extracted by different extractants from soils were compared with REEs contents in winter wheat grown on the soils with a statistical analysis. The result of correlation analysis showed that 0.1 M HCl gave the best estimate of plant available REEs in soils, which suggested that 0.1 M HCl could provide valuable information on plant uptake of REEs in soils studied. |
