Horticulture Diagnostic Labs

Gardeners and ornamental horticulture professionals alike may contact our Diagnostic Labs for answers to their questions about plants, gardens, landscapes and lawns. The Labs also offer diagnostic services to help diagnose plant problems and diseases as well as identify insect and tick specimens. You can phone in questions, or drop off samples and specimens for diagnosis or identification.  We have two locations to serve you better.


Soil Testing

Homeowners as well as commercial growers and ornamental horticulture professionals alike may have soil tested for pH and conductivity (soluble salts). Samples are tested for pH utilizing a Beckman-Coulter digital pH meter. Conductivity readings on samples are obtained utilizing a Thermo-Orion digital conductivity meter. Results of soil tests are sent to individuals via regular mail or email if you choose. Each report indicates the soil pH, the conductivity reading as well as a rate of limestone (if needed) to raise the soil pH into the correct range for the plants/crops being grown in the sampled soil.

The Soil Testing Laboratory is located at the Cornell Cooperative Extension - Suffolk County, Extension Education Center in Riverhead, NY. Samples may be dropped off directly at the Extension Education Center in Riverhead or at the Insect & Plant Disease Diagnostic Lab located at the Bayard Cutting Arboretum in Oakdale, NY. Samples dropped off at the Arboretum will be transported once a week to the Lab in Riverhead. Soil samples can also be mailed directly to the Lab in Riverhead as well. Testing is performed once or twice a week depending on the volume of samples submitted to the Lab.

Cornell Soil Health Testing

Soil health describes the capacity of a soil to be used productively without adversely affecting its future productivity, the ecosystem or the environment. Soil health emphasizes the integration of biological with chemical and physical measures of soil quality that affect farmers' profits and the environment.

The Cornell Soil Health Program Work Team has developed soil measurements to help monitor the state of soil health both in space and time. These indicators can measure soil improvement or degradation resulting from different management practices and also the long term changes in soil health under given management practices.

For more information on the Cornell Soil Health Testing program including all costs, sampling instructions, submission forms, etc. visit their web site at ( http://soilhealth.cals.cornell.edu/testing-services/comprehensive-soil-health-assessment/)


Cornell Waste Management Institute - Soil Quality and Testing

The information on the Cornell Waste Management Institute - Soil Quality and Testing website is intended to help people who are interested in learning about soil contamination, soil testing, interpreting test results, and best practices for healthy soils. Among other subjects a list of laboratories certified by the NYS Department of Health Environmental Laboratory Approval Program (ELAP) to conduct lead analyses is available at this web site. Many laboratories on this list also test for other hazardous materials, air emissions, etc.
