You can?t use heavy metal in NPKS then well. If there is heavy metal then
you must follow under mentioned ratio.
Metal Maximum PPM (Never accept more)
Arsenic 50 PPM
Lead 100 PPM
Cadmium 10 PPM
Mercury 5 PPM
Chromium 500 PPM
Nickel 50 PPM

You must follow up mentioned ratio if you can?t withdraw heavy metal. More
ppm must not accept by our govt.
