The wording in the source

Timing

  • The soil is easier to sample when its moisture condition is suitable for plowing.

    Sampling Procedure

Method

  • Mix the subsamples of a sampling area together in the container, breaking up large clumps. The goal is to provide a representative sample.

    Sampling Procedure

  • Repeat for any separate areas that you wish to have tested.

    Sampling Procedure

Depth

  • Use a trowel, spade, auger, or soil tube to obtain thin vertical slices or cores of soil from the surface to a depth of 6 – 8".

    Sampling Procedure

Cores

  • Repeat this procedure at 11 – 15 locations within the sampling area, placing the subsamples together in the container.

Plan the points to the rule that applies

Set the area per sample, the cores and the depth your rule asks for. GeoPard places the points on a grid or by zone, routes the walk, prints the labels and takes the plan to the field on a phone.
