What is your definition of the word "nitrate" as printed on the instruction sheets of nitrate test kits?
Multiple choice version: Nitrate is A) NO3 B) NO3-N (nitrate nitrogen)
Essay version: what does NO3-N mean?
It would be useful to add the definitions of NO3 and NO3-N to some FAQs, and explain somewhere that when people commonly talk about nitrates, or refer to it as NO3, they're really talking about NO3-N. It's a very confusing issue.
Hope it helps. -- Chuck Huffine Knoxville, Tennessee
