Thank you for sharing that. Nice to see Mr Naka in action.
Does anybody know what he used the nails for?
Naka (and Stanley Chinn) used bits of ferrous metal in their soil to add iron. In this case, the nails were it, as Chansen stated.They're likely there to add iron and help prevent chlorosis. I prefer adding chelated iron as needed.
