Sampling and Preparation

One of the most important aspects of analytical work is the proper collection and preparation of representative samples. The following are some general guidelines on sampling techniques for soils, plants and water. Specific sampling information can be obtained from a variety of sources, including literature and Extension Specialists.

Also included are recommendations for preparing samples prior to submitting them to the UC Davis Analytical Lab. The lab routinely dries wet sample material and also provides sample grinding service (at client cost). If you have any questions regarding sampling or sample preparation, please contact the Lab at 530-752-0147.
