You will need to gather a soil sample to use in your test!
Label your one quart plastic bag or other container to hold at least 1 cup or 250 ml of soil by:
- Documenting the location using latitude and longitude coordinates. If possible, you will want coordinates to the nearest 1/1000000 of a degree of latitude and longitude, e.g., Latitude 40.703283, Longitude -75.216078.
- Documenting depth from surface. Make sure you sample non-organic soils at the site, i.e., soils below the surface topsoil or other surface organic materials
- Writing your name
- Writing the date
