The soil on my tiny veg patch has become very acid through application
of garden compost over many years.

I'd be surprised if the application of good garden compost would have
that effect.

The top surface has a green sheen
to it when dry which I assume to show an acid condition?


Sounds to me like the soil has been damp and you can see the mould/algae
that grew where the water stood?
