It’s a good idea to pull soil samples from the field every two years, Farm Journal associate field agronomist Missy Bauer says in Episode 12 of Corn College TV Season 3.
"That helps us keep pretty consistent on keeping up with the lime needs or the pH levels in the field as well as your overall P and K levels or micronutrients in these fields," Bauer says.

Follow five steps when taking those samples:
- Calibrate your probe to the depth specified by the laboratory that will be processing your soil samples.
- Sample consistently. Labs generally specify a depth between 6 2/3" and 8".
- Pull between 10 and 12 cores from each management zone.
- Store soils in separate bags, one per management zone.
- Use field computers and GPS to know where you’re at in the field.
