Automated methods for ammonium nitrate and nitrite in 2 molar potassium chloride phenylmercuric acetate extracts of soil



Automated methods for ammonium nitrate and nitrite in 2 molar potassium chloride phenylmercuric acetate extracts of soil



Communications in Soil Science & Plant Analysis 16(8): 883-898



Automated methods for determining ammonium, nitrate, and nitrite in a single soil extract containing 2 M KCl and 5 mg/L phenylmercuric acetate are presented. The ammonium method is also suitable for Kjeldahl, soil and plant digests. Amino acid interferences with the ammonium method are reported. Ammonium is determined by a salicylate-isocyanurate method, while nitrite is determined by the colorimetric reaction of N-(1-naphthyl)-ethylenediamine dihydrochloride with sulfanilamide. Nitrate is determined in the same manner as nitrite after the sample has been passed through a Cu2+/Cd reduction column. The difference between the Cu2+/Cd reduced sample and nitrite sample value is nitrate.
