Soil tests are recommended to be taken at a depth of 1-2 feet with a minimum of 10 sub-samples combined to make one lab sample, except for pod testing where there would be one sub-sample per vine/tree or 6 to 8 subsamples per pod.

When sampling sites on berms, placement should be 12-18 inches from vine/tree towards the middle then rotating as needed to stay on the berm and 2-4 inches from shoulder. If drip irrigated, always sample in irrigated areas.
