I think so. The charter says something about 'relevant to gardening in
the UK'. Which about covers what you have said ;-)

But is soil improvement not relevant to gardeners anywhere?

Yes, but how it's achieved in different countries/climates varies. Try
rec.gardens for an eyeopener..they call it soil amendment.
