Kill Roots?:

What is the prescribed dosage of rock salt to control roots in a
drain?

I don't know what a "prescribed" dosage would be, but I myself pour
about 30 gallons of a saturated water salt solution into my leach
field (down line from the septic tank) once a year. *I came up with
this amount from doing research on various sources.

Ok, we're part way there.

How much salt does it take to "saturate" 30 gallons of water?

Can you cite some of those sources so I can do a little reading?
