g'day tony,

i would lay a mass of gypsum down and rake it in then give it a good
water, then put some more manure or organic matter then mulch it with
spoilt hay. or it might be simpler to just put an edge around it and
convert it to a raised bed, see my page for building a garden and also
a link to ausgarden blog for my latest project.

I'll second that suggestion.
