Summary Unlike phosphate, an index of sulphate retention of soils has not commonly been defined. However, sulphate sorption by soils is more sensitive than phosphate sorption to the amount of their colloidal components. Sulphate has less sorption aff

It has been showed that Chao’s method [extraction with 0.1 mol L−1 hydroxylamine hydrochloride (NH2OH-HCl) at pH 2.0 for 30 min], which is commonly used to extract manganese (Mn) oxides and occluded heavy metals from soil samples, is not suitable
