Does anyone know of a company that will take your soil samples to test for Round-Up?

[Baitball Blogger]

Near the house, a large swatch of weed grass was killed off by what looked like a very aggressive spraying. I understand there are two types of Round-up. One that is "safe" to plant after a day. And another that takes a year. I just want to see which one I'm dealing with.

I think it's pretty safe that I won't get a straight answer from the owner if I ask.

1. Try your state's extension office for advice. Sometimes local colleges will help test soil samples.

No promises. But you never know until you try.

4. Yes. That is good advise

The semester we taught soils at college, all students had to get the sample box and mail in multiple soil samples from within test plots.
Back then the office would mail you the sample box with all instructions to comply with sample technique. A complete analysis will be mailed back.

2. Check to se if there's a county cooperative extension service, affiliated with the state agriculture department,

in your area. They may do soil sample analysis, although not sure if they can test at a level that finds chemical residue.

3. Have you tried contacting the Co-operative Extension Service at a local university ?

6. You all have been so incredibly kind!

I will follow the advice and if it turns out to be the bad one year round-up, I'll do a follow-up.

Thanks again!

7. For The Consumer/Lawn Care Market...

...Bayer quit using glyphosate in Roundup.
A glyphosate containing formula is still made for industrial/agricultural use, but comes in much larger volumes than a homeowner would use.
Glyphosates, no matter the starting concentration, take at least 4 months to go away, either by weeds metabolizing them (and dying) or washed out of the soil where some species of nitrogen fixing bacteria can biodegrade them (slowly!).
There is no glyphosate containing product that leaves the soil usable in 24 hours.
So, if you find a site to test your soil, they should be looking for the presence of glyphosate. Any of the replacement active ingredients would be gone by now.
I worked with Bayer on an ideal surfactant system to create a stable emulsion of these water insoluble active ingredients, particularly the water-white & clear products used for lawn care. No glyphosates in those products either.

8. Wow! Thanks ProfessorGAC.

I don't know if I am able to send pictures through PM, but if it's allowed, would you like to see what it looks like? Maybe you can recognize it by the way the burn-looking site looks like? I can't post it on open forum for obvious privacy concerns.
