Bibliography

Provides guidance on how to store and preserve soil samples for laboratory determinations and how to prepare them for analysis after storage.

This International Standard gives guidance on how to store and preserve soil samples for laboratory determinations and how to prepare them for analysis after storage. Special emphasis is given to maximum storage times as a function of different storage conditions.
