I am looking for elaboration for measurement of nitrates and ammonium in soil through SKALAR METHODS, but the SKALAR instrument that we have in our Lab, there I have seen, mentioned only for nitrate+nitrite, ammonia and ortho phosphate, how I can calculate ammonium in this method? because I want to estimate the ammonium and nitrate to find out ammonification and nitrification?
Do your SKALAR equipment did have the cadmiun column? If you don´t passed through the column containing granulated copper‐cadmium you will measured only nitrite. if you pass the sample through the column you will measured nitrate+nitrite.
Amonia you do it in another channel of the equipment.
best regards
In addition to Eluterio's information, the ammonia is measured separately, usually by using an indophenol reaction. The extraction of nitrates and ammonia from soil is a standard procedure and the extractant is usually a KCl solution
Please have a look on the attached PDF. It will helpful for you. Good luck.
