Soil Sampling Quick Tips

  • Order your Supplies NOW, before you start soil sampling.
  • Turn on “Location” (Android) or “Location Services” (iOS) to enable your GPS. Find this under Settings on your mobile device.
  • Sync your device often. If your connection is minimal, we recommend waiting to SYNC your device until you have a good connection. The better the connection the faster the SYNC process.
  • Use clean equipment. Rusty or galvanized equipment contaminates soil samples.
  • When building a job, play with the grid. Move it around, make it bigger or smaller. REMEMBER: the grid is just a guide.
  • Very Important: Print your shipping sheet and place it in the box with your samples.
  • If it’s dry enough to drive through the Field with an ATV, it’s dry enough to sample.
  • Pull 6 inch cores.
  • Soil sampling wet or dry, doesn’t matter, the lab will dry it for you.
