Need to do some serious weeding and want to use something that will be
neutralised once it hits the soil - need to plant in around three months.

The label on Roundup says it's inactivated on contact with soil and can be
used before planting veg. It says you can replant next day (or after 7
days
if the max strength was used for dense weed cover).

Inactive on contact with soil, are you sure?
I thought it had a 40 day half life in the soil although it only works on
green material. i.e. the chemical stays in the soil for some time before
being degraded.
