Extraction of boron from CSSC reference soils by hot water, dilute CaCl2 and mannitol-CaCl2 solutions



Extraction of boron from CSSC reference soils by hot water, dilute CaCl2 and mannitol-CaCl2 solutions



Canadian Journal of Soil Science 66(2): 377-381



CSSC (Canada Soil Survey Committee) reference soils were extracted by hot water, dilute CaCl2, and by mannitol-CaCl2 solutions and boron was determined by either azomethine-H or the curcumin method. Results were strongly method dependent; in particular results by the simplest method, mannitol-CaCl2, were generally lower and not highly correlated (r = 0.64) with those by the recommended procedure.
