Sorry Chris, misread your post but agree seaweed is an excellent soil improver.
I can't get enough to cover the garden but sufficient to use it as a mulch in pots, it dries out and rots down very quickly and doesn't smell when used raw.
I made liquid feed from seaweed this year and found it only smells when used in liquid form, in the bin, when the lid was lifted, the smell was enough to make your eyes water but toms and spuds love it and bottled up it keeps for several weeks.
I rinse the seaweed in water first because of salt content but read somewhere there is so little salt on seaweed it doesn't really matter whether it's rinsed or not.
It's also good as a spray to deter some pests like slugs and snails but you need to start spraying early - March time. It's wildlife friendly to, the birds don't seem to mind the smell neither does the cat, which only lasts for a few hours after spraying .. if you have ever lived by the sea it's not unpleasant but land locked gardeners might not like it.
