A rapid method for determination of nitrate, nitrite, and ammoniacal nitrogen in soils uri icon


  • 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'sreagent, NO2-N by x-naphthylamine and sulphanilic acid and NOa-N byphenol-disulphoric acid. The method will suit small laboratories and 50 to 75samples can be analysed in a day
