Seedmeal- Enough Nitrogen?

[ARgardener]

I converted the recommended nitrogen (per soil test) to a seedmeal based fert. using soybean meal and alfalfa meal. I converted and measured so that the amount of N present in the seedmeal is exactly that of what is recommended I applied.

I'm wondering, though, is there some other variable I'm looking over? Will my seedmeals be able to provide sufficient N or does it need to be supplemented with another source?
