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.
