Full Description

Describes a procedure for determining the acid soluble sulphate content of natural soil which includes all naturally occurring sulphates apart from negligible rarities. The results obtained give the sulphate content at the time of sampling only as the sulphate content is subject to seasonal fluctuations. The method can also be used for the determination of the sulphate content of 1 : 1 soil : water extract, or the sulphate content of groundwater. To be read in conjunction with Part 1.
