Soil Sampling
Tools:
- Walk a zigzag course around or through the area to be sampled taking 20 to 30 cores, enough to make a quart of soil, stay away from edges of field.
- For furrow or field crops, take soil 12 inches below the surface or to the plowing depth.
- For tree and vine crops, soil samples should be taken at one-foot increments to the depth of rooting. This may require three to five samples from the same area.
- Mix sample well and place in quart-size bag.
- Mark each bag with sample description or location.
