Have just read the book called "Livingn Energies" by Callum Coats which is about the genius of Viktor Shauberger. What he didn't understand about the environement isn't worth knowing I don't think! However, the book talks about remineralizing the soil with stonemeal, better known as rock dust or crusher dust, but I have no idea how much one should spread per square metre or whatever. Anyone got any ideas? ???
