Like many others, I am concerned about poison in the food I grow. After a week of inaction, I contacted Wy'East and got the necessary forms for soil testing. The process is straight forward: gather samples on a dry day and place them in labeled baggies while documenting the process on a chain of custody form. The lab tests each sample for a moderate price.

Ultimately, this was all a mute point, because the ground in my back yard is inhospitable to plants. It was initially advertised as "backyard RV parking". This amounts to a strip of clay-like dirt, covered in gravel. Digging in this soil was extremely difficult. The shovel I purchased for the job bounces off the gravel bits embedded in the clay. The process of making a hole was more like scraping than digging. I would not classify this ground as dirt.
