Soil Sampling Procedures

SOIL

Sampling areas should be grouped according to some common denominator such as management zones, irrigation zones, soil types, plant types, plant varieties, topography, etc.

01

Sample

The sample should consist of a random composite sample of the sampling area.

If diagnosing a problem, the soil should be taken exclusively from the problem area(s).

02

Sampling instructions

Each sample submitted for testing should consist of soil taken from the root zone of the plants being grown from 5–6 different locations within the area to be tested.

Due to possible contamination, the surface 1–2” should not be included in the sample.

Any areas that are exhibiting problems or have been managed differently should be treated as separate sampling areas.

03

How to Label Samples

Each sample should be labeled on the OUTSIDE of the bag with the identification that will best identify it for your purposes. Please be brief in the labeling. 

04

Sample volume & shipping

Each sample should consist of one quart or one liter of soil.

Samples should be shipped in plastic bags, such as zip-lock type bags, inside a mailing envelope or box.

Considerations in Soil Sampling

  • Schedule sampling for plant selection or construction
  • Random composite samples for pre-planting or monitoring
  • Sample specific areas for diagnosing problems
  • One quart (liter) of soil per sample
  • Label on the outside of a plastic, zip-lock type bag with indelible marker
  • Provide as much information as possible

Water Sampling

  • Water samples should be taken from a location that best represents the use of the water, such as from a hose, sprinkler or drip emitter.
  • Use a clean plastic bottle, preferably one that has been previously used to store water. A drinking water bottle is suitable.
  • Each water sample should consist of one quart or one liter, in a plastic bottle, filled completely.
  • If the sample will be shipped to the laboratory, the bottle should be placed into a plastic bag to avoid leaking into the box. It sometimes helps to use some Teflon tape on the threads of the bottle to reduce the possibility of leakage.
  • Please label the bottle with water-proof ink!! If the sample cannot be submitted within 24 hrs, refrigerate.
