It is known that in areas of the Murray River where drought has occurred, some of the soils have turned so acidic (in some cases PH1.8) thier is thought that alkaline (such as lime) should be added to try and neutralise the soil.
I believe that as it it natures way, no alkaline should be added. If the local nature dies, so be it. Nature will revert eventually and redress the situation. What do BE think?

I think your argument stands or falls on whether the drought has been caused by nature or has it been driven by man's urbanisation of the surrounding areas.
Phew I nearly sounded smart there. I'm getting dizzy, think I need to sit down.
