How is nitrogen content measured in soil?
(OP)
When a farmer sends in a soil sample, how does the lab determine the nitrogen content? Is it possible to measure it on-site? I know next to nothing in this area, so use small words.:)

In the US most labs follow SW-846. I have attached a link to the nitrate nitrite test for you to see how it is run. I hope this helps:

I was thinking you could try HACH field Equipment to test for nitrogen in field. It may be just an indicator, but maybe enough for you. Here is the link:

If that does not workgo to:
www.hach.com
Type in nitrogen soil and see the results for soil fertility kit.
Hope this will help you in the field.
