    Abstract - (Show below) - (Hide below)

    When samples are taken from a batch of fertilizer, an increment is taken from N units. Each of these increments may be taken either by partial sampling devices, if absence of any particular bias is assured, or by treating complete item with a reduction device (absence of bias). Describes for the latter case, the extent of mass reduction beyond which error in representativity of the increment is not negligible. May be used to determine minimum mass of any intermediate increment during sample processing. Where partial sampling devices are used, this limiting mass can be much more important.
