ABSTRACT
Exchangeable ammoniacal nitrogen in soil was determined using molecular emission cavity analysis. Various parameters were identified including optimum sample weight and condition , extraction time and concentration of pottasium chloride. The method is simple, sensitive and rapid. NH+4-N can be measured in one minute, and this is important since soil nitrogen changes considerably with time.
