I know I can send soil samples to my local university extension office for testing, but how do I test soil for glyphosate-based herbicides, lead, arsenic, and other contaminates?
As a citizen scientist I’m about to get into composting more on my property and would like to know more.
Awesome! Thank you!!
I am about to start to attempt to collect compost feedstock from various resources and not sure how to tell if chemicals were ever used.
Thanks for the info!
