I have certainly heard and read that organic nitrogen (ammonium
something-or-other) is capable of burning because of being available too
rapidly, but that mineral nitrogen (nitrate) was much slower to dissolve
and seldom dangerous in any concentrations (in our sandy soil, that is).
Any chance you flip-flopped the two kinds?
