An Evaluation of Mogilevkina's Method of Determining Fixed Ammonium in Soils1

Abstract

Abstract

Studies using soils and ammonium-saturated clay minerals showed that Mogilevkina's method of determining fixed ammonium gave much lower values than HF methods and was unsatisfactory. The heat treatment used in this method for removal of organic-N and exchangeable ammonium-N leads to loss of fixed ammonium, and the Kjeldahl procedure used to determine the nitrogen in the residue from this treatment fails to recover this nitrogen quantitatively.
