N2  - A rapid procedure is proposed for simultaneous determination of NH4-,
NO~-, and NO3-N in field moist samples. The procedure involves extraction,
with Morgan's solution followed by determination of NH4-N by Nessler's
reagent, NO2-N by x-naphthylamine and sulphanilic acid and NOa-N by
phenol-disulphoric acid. The method will suit small laboratories and 50 to 75
samples can be analysed in a day.
