This European Standard specifies a method for the determination of nitrogen in soil improvers and
growing media. The dry combustion method was developed originally as a manual method by Dumas
[5]. Its application is improved greatly due to the use of modern automated equipment and is
applicable to all forms of nitrogen.
The method is not applicable to liming materials and preformed materials such as mineral wool slabs
and foam slabs.
NOTE The requirements of the standard may differ from the national legal requirements for the declaration of
the products concerned.
