Which adjectives can replace prolific in...

[qs]

If I wanna describe a writer who writes lots of works.

I could say he is a prolific writer.

Are there any others adjectives can replace the word prolific here?

fertile? productive?.......THX

'Prolific' is the natural choice. 'Fertile' could mean quality, not quantity; 'productive' smacks mostly of efficiency.
