Can anyone recommend an organic nitrogen source, please?

Almost anything that comes out of an animal - assuming it has been
reared and fed organically!

Although, I seem to recall that recent EU legislation (agreed by
the
UK goverment) means it is all now controlled, needs licences, etc
....

Perhaps Tone is concentrating it for his hair?

As far as I know, plant foods of animal origin have been controlled
and licensed all my life. I certainly hope so. They've probably
sharpened up the regs since recent disease scares.
