This European Standard specifies a method for the determination of nitrate and ammoniacal nitrogen with
reduction using Devarda alloy (modified for each of the variants a, b and c).
The method is applicable to all nitrogenous fertilizers, including compound fertilizers, in which nitrogen is
found exclusively in nitrate form or in ammoniacal and nitrate form.
