Hi Cecilia and James-
The links I sent had links to companies that offer additional soil testing beyond the basics. From the Soil for Water article they shared these 4 labs:
Regen Ag Lab https://regenaglab.com/
Ward Laboratories: https://www.wardlab.com/services/soil-health-analysis/
Woods End Laboratories: https://woodsend.com/
Cornell Soil Health Laboratory https://soilhealthlab.cals.cornell.edu/testing-services/soil-health-analysis-packages/
The link to Dr. Ingham's Soil Food Lab page: https://www.soilfoodweb.com/laboratory-technicians/ has too many for me to list, but they are on there because they specifically test for biological life in the soil.
Also I found this list from Michigan State University that has additional suggestions https://www.canr.msu.edu/news/testing-for-contaminants-in-soil-water-and-plants
Unfortunately, I have never used any of these services personally so I can't give you any first hand experience with any of them, but perhaps if you contact them they can provide an example of what their end analysis/report looks like so you can decide if they can provide you with what you are looking for before you send a sample/pay their fee.

That was what I found out earlier, most places only do testing for nutrient levels which does not help me. I could not find a place that would test for contaminants, pesticides, etc

I've actually had a pretty underwhelming experience with soil testing through a local service recently. The turnaround time was way longer than expected, and the report I got back was super basic - didn't offer much insight beyond pH and a couple nutrient levels.
I was hoping for something more actionable, especially since I'm working with kids and wanted to tie it into a learning activity. It ended up being more confusing than helpful, which was a bit disappointing.
If anyone has recommendations for services that offer more detailed results (and explain them in a way that's easy to understand), I'd really appreciate it. Just didn't feel like I got much value out of this round.

Hi everybody,
I teach at a high school in Miami, FL, where we have been growing a garden for many years. This year our administration decided to revamp our land lab and moved our garden beds to another side of the land lab. Unfortunately they did not move the soil I have been nurturing for all these years, nstead, they brought in soil from a donor that I know nothing about.
I am concerned about growing food in that soil next school year because since the three months the soil is there, no weeds have grown and there is no sign of life besides fire ants. In my previous soil, in a couple of days all sort of plants would grow, a healthy sign in my opinion.
I would like to have that soil tested before the start of the next school year, does anybody know of a place I can send samples to? I would like to know about any pesticide residue and contaminants if possible.
Thanks everyone!
Cecilia
