Bibliography
This document specifies a method for the determination of the ammoniacal nitrogen content in fertilizers. The method is applicable to all nitrogenous fertilizers, including compound fertilizers, in which nitrogen is found exclusively either in the form of ammonium salts, or ammonium salts together with nitrates.The document is not applicable to fertilizers containing urea, cyanamide or other organic nitrogenous compounds.
