Introduction
Soil improvers and growing media are very difficult to sample because of the variety of materials used
and the inhomogeneous materials involved. When packed, some of them are also by their nature and the
packaging and palletisation process subject to pressure which results in various degrees of compression
which need to be counteracted prior to sampling.
The task is further complicated by the variety of sampling apparatus that can be used, the quantity to be
represented by the sample and the
