Soil improvers and growing media - Determination of nitrogen - Part 1: Modified Kjeldahl method
Abstract
This European Standard specifies a method for the determination of nitrogen in soil improvers and growing media. The Kjeldahl method determines ammonium-N, nitrate-N, nitrite-N and organic N content of soil improvers and growing media. Nitrogen in N-N-linkages, N-O-linkages and some heterocyclics (especially pyridine) is only partially determined. [7], [8], [9]. NOTE The requirements of the standard may differ from the national legal requirements for the declaration of the products concerned.
