Commercial growers, gardeners, and homeowners use soil, plant, and water analyses to help them make decisions about the use of soil amendments and other management actions. Home and business owners may also wish to test their soil or drinking water quality.
In June 2017, Oregon State University Extension Service compiled and published a list of analytical laboratories serving Oregon that perform Soil Testing, Water Analysis, Plant Analysis, and Disease Testing/Identification. This list also includes information on nutrient management guides, testing for contaminants, and tips for submitting your sample to a laboratory.
Check out the list below:Analytical+Laboratories+Serving+Oregon.pdf
To compile this list, the authors requested information directly from laboratory managers. Neither Oregon State University, the OSU Extension Service,
nor the Columbia SWCD makes any endorsement by listing a laboratory, nor does omission of a laboratory indicate anything about the quality of its services.
You can find other sources of laboratory services with an internet search or in the yellow pages.
