Our Laboratory

Accurate, precise, and timely results!lab1

Soiltest's quality laboratory has been serving the Northwest since 1976. We provide professional analytical testing for soil, water, plant tissue, feed and nematode samples.

Our lab provides next-day results for feed, soil and plant tissue analysis. Quality results coupled with timely reporting make our services the best in the area.  We focus on delivery options that are also convenient to the customer.  We are able to deliver reports via: e-mail, fax and mail. Note, nematode identification sometimes takes 2-4 days to complete and water analyses can take up to 14 days to complete.

Quality Control

Soiltest's greatest strength is our quality.  Therefore our lab follows a strict QA/QC program to ensure accurate results. All of the procedures are documented and maintained by our standard operating procedures.  A minimum of 12% of the samples analyzed are quality control samples comprised of blanks, references and duplicates. Our laboratory is certified by the Washington State Department of Ecology.  The quality control measures needed to maintain DOE certification are also applied to our agricultural samples.

Proficiency

IMG 0016

Soiltest participates and excels in several proficiency testing programs.  Soiltest is committed to providing accurate and precise results in all our analytical work.  To assure this quality we participate in several sample exchange programs.  Soiltest analyzes soil and plant samples quarterly under the North American Proficiency Testing Program.  Quarterly manure samples are analyzed under the Minnesota Department of Agriculture Manure Testing Laboratory Certification program. DOE certification requires that the Soiltest laboratory pass quarterly water sample submissions.  This means that the test results you receive are always as accurate and precise as humanly possible.

Nematode Analysis

Soiltest offers nematode identification in soil and root samples.  We can conveniently test for fertility and nematodes from the same soil sample bag.  Be careful not to freeze or over-heat samples destined for nematode analysis.
