Can you elaborate a bit on that? What does organic nitrogen mean? AFAIK, the organic form is not accessible to plants as it is a too complex compound, just like organic carbon. It needs to be broken down to more simpler, inorganic, forms like NH3/NH4 before the plant can use that. The fertilizer nitrogen is indeed inorganic. Although plants prefer NH3 and NH4 before NO3.
