Taking a leaf out of BM's book

[Penellype]

My money would be on the manure, as long as it is manure that is rotted at least a bit first. I've planted out some winter cabbages in soil top dressed with the contents of a year old hotbed (the bed has already grown some huge onions) and the cabbages are romping away.

I woud think BFB would be next, although it would probably depend how much of it you added. Nettle tea 3rd, ditto.

Thumbs down for the woodchip as a short term fertilizer, great for improving soil structure as has already been said.

I await the results with interest

ooh ohh I vote 3! My heavily researched, highly thorough crop rotation plan says manure before brassicas (if I could do a thumbs up I would )

Bed 1, soil mixed with wood chips
Bed 2, soil fed with BFB
Bed 3, soil fed with manure
Bed 4, no soil enhancement but growing plants fed with nettle tea

I'd reckon the best (in descending order) would be:

Bed 4 if fed regularly as nettle tea is a week feed but a good source of nitrogen so will help with leafy growth.
Bed 3 again because manure is a good source of nitrogen but this will decrease with time whereas the nettle feed is ongoing.
Bed 2 because BFB is a good balanced feed
Bed 1 because the woodchip will rob the soil of nitrogen as it breaks down
