Hi,

On Sunday, I accidentally and unfortunately used a residual weed killer
in an area where I intend to plant a lawn later in the year. The weed
killer was from an Irish manufacturer (Gouldings "CleanUp") and
contains Aminotriazole (40%) and Atrazine (60%). (Atrazine seems to be
banned by the EU, strange).

Does anyone have any advice as to how I might neutralize the weed
killer? There has been little or no rain and a lot of sun since I put
down the weed killer. The ground is very hard (back garden in a new
build). I've already tried with some success to scrape off the top inch
of soil and then dig over to a depth of about 6 inches to expose
untreated soil. Any idea if this will work?
