This European Standard specifies a method for the determination of nitric and ammoniacal nitrogen with
reduction according to Arnd (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.
