Taikymo sritis

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. Its application is improved greatly due to the use of modern automated equipment and is applicable to all forms of nitrogen. NOTE The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.
