The wording in the source

Timing

  • A regular soil testing program should be followed in fields by sampling at least every three years or when the cropping system in a field significantly changes.

    Soil Testing

  • The best time to sample from a logistical standpoint is in the fall. However, when establishing a forage crop, soil samples should be collected at least six months prior to establishment to allow for soil pH adjustments, if necessary.
