Quantitative assessment of plant‐available silicon ...
· However, there are numerous methods to estimate plant-available Si and some have limitations when Si has been applied. We evaluated four published extraction methods (1-h CaCl 2, 16-h CaCl 2, CH 3 COOH, and PO 4) and a 4-h CaCl 2 extraction method. We related soil-extractable Si to plant Si in Si-rich rice straw and husk.
