What are the implications of 'sour soil'?

It will become exhausted of nutrients and because it is an enclosed environment without rain to wash out impurities it could have a build up of salts, like the little crust you get around the top of plantpots. It could also have pests and diseases in it.
I made the mistake of thinking that if I 'beefed' up the bedsoil with loads of farmyard manure this would cure any soil sickness...............it didn't!
The only way is to dig out all the bedsoil to at least one spit deep and replace it, or else you will suffer from diminishing returns each year!
