As an experiment I've used a large deep plastic tray/box of compost as a
seed bed.

I sowed four drills of different herbs across the box (and thought I would
remember which was which!) and seedlings are now emerging.

However there isn't a nice stright line across the box, but clumps of
germination and spaces.

It is possible/likely that I didn't spread the seeds evenly.

However it is also possible that I sowed fine seeds a bit too deep.
If that is the case, would gently stirring up the fallow bits perhaps
stimulate a second burst of germination?
I am assuming that someone has had a similar problem and tried various
methods to solve it.

Yes, but not typically in seed trays. If you discover a cause, please
let me know - I am still defeated after 40 years' of trying to find out!
