Is it possible to treat crop with chemicals, without poisoning the soil?

Hello-
I'm in pursuit of purchasing land. In inquiring about 2 sites, I asked the agent what type of chemicals has the farm land been exposed to:

PROPERTY 1 (51.33 acres): "recently exposed to Corvus, Atrazine, Roundup. Nothing in ground just on top. The chemicals deplete after one year."

PROPERTY 2 (19.4 acres): "recently exposed to
BICP II
Magnum 1.2
Simizine90- one pound per acre
Atrazine90 – ½ pound per acre
Fertizilier has been put down for next year’s crop"

My thoughts are to keep searching. Do you second that motion?

Yes, I'd keep looking.

As with anything, "it depends"

If you find a place with all the features you want (slope/a creek/outbuildings/woodlot/commynity/whatever) and it's been sprayed but you have time and money to do remediation, go for it.

Yeah. I would keep looking.
However, if you are looking at commercial farm land, I doubt you will find anything 'clean'.

"Deplete in one year" is a very doubtful statement. Certainly less effective, but not depleted.
If tou want to get certified 'organic', there will be a minimum 3 year wait, along with some expensive soil analyses along the way.

But keep asking for the chemicals. It is a really good thing when people ask, until the farmer realizes that his land has less value if he uses chemicals.
