"Is it possible to put nitrogen in a form that is +?"
Yes, the ammonium ion NH4+ has a +1 charge, it's present in ammonium salts (duh  ), and ammonium nitrate does fall into that category, so the chelating agents that this company sells will retain some of the nitrogen in
case of [[5Ca(NO3)2].NH4NO3.10H2O]].

I think you've got the right idea now about the positive ions being capable of being chelated. With NO3- (nitrate) this nitrogen containing ion
is not shown chelated with the lignosulfonate. But, if the nitrogen is contained in the NH4+ (ammonium) ion then then it is chelateable. All the
chelated ions shown are positive ions. Most are metals but there are some exceptions like NH4+.

Thanks heaps!!!
I feel like my understanding of the way calcium nitrate and chelating agents work. This site is so handy.
I wish you well in your future discussions, and if you need a hand in growing citrus, especially navels - leave a message and I'll try to help.
